Answer:
B. Stomata closes, cutting off transpiration.
Explanation:
On a hot, dry day (or after several days with no rain or watering), transpiration causes more water to be lost than is coming in, and the water balance within the plant can get thrown off. The dehydrated collapsing cells in the leaves and stems can no longer remain erect, and the plant begins to wilt.
Answer:
Option- C
The roots begin to rot, causing them to no longer uptake water. As, there is specific amount of molecules and nutrients requirement for any plant to develop and survive through time. While, the oxygen is always been necessary for the survival of all plant and animal life. While, due to some reasons if the roots of the plant are not able to absorb enough of the oxygen and other molecules then they will face the process of wilting or shortage of nutrients in there body causing the damage to there over all structure.

How has the eye accomplished correction for spherical aberrations? Fill in the blanks. The _____ is flatter at its ____ than at its ______, and the ______ is denser in the center and hence refracts more strongly at its core than at its outer layers.
Answer:
Cornea, margin, center, lens
Explanation:
Spherical aberration is defined as a class of aberration which is found in various optical systems which use the elements with various spherical surfaces.
The eye accomplished correction for spherical aberrations through cornea and lens.
The cornea is a transparent front part of eye. In humans, the cornea's refractive power is about 43 dioptres. The cornea is flatter in shape at it margin than at its center.
The lens in the eye focuses light rays which pass through it so that clear images of objects can be created which are positioned at different distances. Eye lens is of ellipsoid and biconvex shape. It is denser at the center.

The molecules that make up food contain energy. How does the human body get energy from the food molecules?
A- by breaking and reforming chemical bonds in the molecules
B- by combining the molecules together
C- by using them to from ionic bonds
D- by adding energy to the molecules
Answer: A: by breaking ans reforming chemical bonds in the molecules
Explanation: There is energy stored in chemical bonds between food molecules (this is referred to as ATP, or Adenosine TriPhosphate, which is the type of energy your body uses). When chemical bonds are created, some energy is stored in those bonds (personally, I like to think that it's because the bonds need energy to stay bonded, but there is no science to prove this). When one of these bonds are broken, the energy that was stored is released, and can then be used by your body. Your body then uses a different type of energy (called ADP, or Adenosine DiPhosphate) to reform the bonds, which then go on to become waste products.
Answer:
It's A. By breaking them down and reforming chemical bonds in the molecules.

What is the role of renin in the secretion of aldosterone?
Answer:
Explanation:
Aldosterone is a hormone which is produced by the adrenal glands which are present above the kidneys. The role of aldosterone is to regulate the blood pressure. It causes the reabsorption of water and salts into the bloodstream during the kidney filteration process. Hence, maintains the blood volume, restors blood pressure and salt level.
Renin is an enzyme. It facilitates chemical reactions which stimulates the synthesis of angiotension II, it directs the synthesis of aldosterone.
Renin, produced by the kidneys in response to low blood pressure or blood volume, triggers a chain reaction leading to the secretion of aldosterone. Aldosterone then promotes sodium and water reabsorption in the kidneys, thereby increasing blood volume and pressure. This process is part of the renin-angiotensin-aldosterone system (RAAS).
The role of renin in the secretion of aldosterone is crucial in the regulation of blood pressure and fluid balance, through the renin-angiotensin-aldosterone system (RAAS). When blood pressure or blood volume is low, specialized cells in the kidneys, known as juxtaglomerular (JG) cells, secrete the enzyme renin. Renin then catalyzes the conversion of angiotensinogen, a blood plasma protein produced by the liver, into angiotensin I. This is further converted into angiotensin II in the lungs by angiotensin-converting enzyme (ACE). Angiotensin II serves multiple roles:
It acts as a potent vasoconstrictor, narrowing blood vessels to increase blood pressure.It stimulates the release of the hormone aldosterone from the adrenal cortex.It increases thirst and the secretion of antidiuretic hormone (ADH), both of which contribute to raising blood pressure.Aldosterone promotes sodium and water reabsorption in the kidneys, which increases blood volume and blood pressure. This process ensures homeostasis in the body by adjusting fluid and electrolyte balance in response to varying conditions.

What are the receptors for static equilibrium?
The receptors for static equilibrium are mechanoreceptors located in the inner ear. They include hair cells with stereocilia which are found in the vestibule of the inner ear. These receptors detect gravity and linear acceleration, contributing to the individual's sense of balance.
Explanation:The receptors for static equilibrium are specific types of mechanoreceptors located in the inner ear. These receptors, known as hair cells with stereocilia, can sense head position, movement, and the body's motion. The hair cells are situated within the vestibule of the inner ear. Specifically, the utricle and saccule sense head position, and the semicircular canals sense head movement. These cells respond to static equilibrium stimuli including gravity and linear acceleration (such as when the head changes orientation or moves in a straight line). All the signals generated are transmitted through the vestibulocochlear nerve to the brain stem and cerebellum, allowing the body to maintain balance.

A(n) _____ force is the overall force on an object after all the forces are added together.
Answer:
Net
Explanation:
A Net force is the overall force on an object after all the forces are added together.
Answer:
The correct answer would be Net force.
Explanation:
A force is the interaction with the object which changes the motion of that particular object when there is no opposed interaction. There are many forces which are present in the atmosphere and have impact on the objects, but such forces cannot be felt until and unless they become severe in nature. There are gravitational force, Wind Force, Frictional Force, etc. All these forces are so small that they can't be felt and the balance of the object is not disturbed. These all forces combine to make the Net Force. So Net Force is the overall force on an object after all the forces are added together.
An atom that undergoes radioactive decay and has a large nucleus most likely contains
Answer:
An atom that undergoes radioactive decay and has a large nucleus most likely contains a high neutron-proton ratio.
here is the full questiojn below.
An atom that undergoes radioactive decay and has a large nucleus most likely contains:
(a) a high neutron-proton ratio.
(b) a low neutron-proton ratio.
(c) more protons than electrons.
(d) more electrons than protons.
Answer:
(a) a high neutron-proton ratio
Explanation:
An atom that undergoes radioactive decay and has a large nucleus most likely contains a high neutron-proton ratio. This stance is true because, the neutron–proton ratio of an atomic nucleus is the ratio of its number of neutrons to its number of protons. Among stable nuclei and naturally occurring nuclei, this ratio generally increases with increasing atomic number. This is because electrical repulsive forces between protons scale with distance differently than strong nuclear force attractions. As such, an atom that requires to undergo radioactivity and has large nucleic will most likely contains a high neutron-proton ratio.
Isotopes are atoms with the same atomic number i.e (the same number of protons) but different mass number (i.e number of neutrons). Isotopes are named according to their mass numbers; example chlorine-35, and chlorine-37. Their atomic numbers remain as 17 but neutron numbers differ (35 and 37).
Which of the following describes the chromosomes in a fertilized egg?
A. Only from the mother
B. Only from the father
C. The diploid number
D. The haploid number
A fertilized egg contains the diploid number of chromosomes, which includes one set from the mother and one from the father, totaling 46 chromosomes in humans.
Explanation:The chromosomes in a fertilized egg are diploid, which means they contain two sets of chromosomes, one set from each parent. In humans, this amounts to a total of 46 chromosomes, with 23 being maternally derived (from the mother's egg) and 23 paternally derived (from the father's sperm). Therefore, the answer to the question would be C. The diploid number. Haploid cells, like the sperm and egg, have only half the number of chromosomes, which combine to form a diploid cell during fertilization. This cellular fusion results in a zygote, the initial cell of a new organism that contains a full set of chromosomes.

Ovules
A
Explanation:
The ovule can be found on a megasporophyll, which itself is located on a scale. On each megasporophyll of the female strobilus two seeds can develop after fertilization. In each megasporangium (the female carrier of spores) a megasporocyte is present which leads to four megaspores after meiosis.
A garden aboard the International Space Station allows space scientists to research the growth of plants in space. This research is important because astronauts will need to grow their own food to survive long space journeys.
What challenges would you expect scientists to face when growing plants in space? What challenges will the astronauts have with meeting their own energy needs?
Scientists are also evaluating plants for gene mutations that would help them grow better in space environments. What traits could a plant have that would help it grow better in space?
Answer:
Some of the challenges that scientists might face in space when growing plants would be the fact that plants must have carbon dioxide to carry out their process, which is why they are grown in special chambers. It is true that the astronauts would put off some carbon dioxide, but perhaps not enough. You would also be trying to grow plants in a zero gravity environment, which they aren't accustomed to.
The astronauts would have to be able to provide an extremely large amount of food in order to meet their nutrition needs. There would have to be enough room to grow an adequate amount of food aboard the ship. The plants would also need to be able to produce more than one crop per growing.
If scientists could genetically modify plants to help them grow better in space, they would need to make them able to thrive in a low gravity setting. They would also need to try and engineer them to need less water to survive. They would need to be strong enough to survive the lift off when going into space. The plants would also need to be able to regenerate and produce vast quantities of food.
Explanation:
The challenges that you could expect scientists to face when growing plants in space are microgravity, limited space, light availability, etc.
Scientists are anticipated to confront many obstacles while cultivating plants in space:
Microgravity: The lack of gravity in space has an impact on plant growth and development. Space and resources are limited inside a spaceship or space station. Because sunlight is restricted in space, artificial lighting systems must be employed for photosynthesis.Temperature and humidity control: It is difficult to maintain appropriate temperature and humidity levels within a spacecraft's controlled environment.Astronauts, on the other hand, may encounter difficulties in satisfying their own energy requirements during extended space journeys:
Food supply is in short supply.
Nutritional necessities.
Energy use.
Plants with the following characteristics may grow better in space:
Dwarfism: Due to restricted vertical growth area and lower gravitational effects, plants with shorter height might be favourable in space.
Compact and efficient root systems: Plants with well-developed root systems that can absorb water and nutrients in tight locations will flourish in space habitats' limited root space.
Thus, scientists are currently researching and performing experiments to find and create plants with these desired features in order to increase the effectiveness of plant growth in space and enable astronauts to generate their own food sustainably during extended space trips.

So, Crocodiles are the closest living relatives of the birds and they sharing the most common ancestor.
How does deforestation affect the water cycle
Answer:
Explanation:
Deforestation is a precursor to desertification. A desert is an extremely arid region with little to no rainfall. How does this happen?
Plants contributes a significant proportion of water to the water cycle. During transpiration, water evaporates from the body parts of a plant and this water goes to the atmosphere. The water cools and condenses to form precipitation
When forests are removed, this significant proportion of the water cycle is lost. The water from plants would no longer be available for precipitation. Such an area will suffer drastic changes in the amount of precipitation it receives.

Use the model to explain how celiac disease interrupts the normal transportation of energy and other nutrients from the digestive system to the circulatory system.
Answer:
According to the model, the "villi" of small intestines is being damaged as an impact of celiac disease. Small intestines are responsible for absorption of nutrients and minerals from food, this occurs through villi, in case of damaged villi absorption is interfered, thus disturbing the digestive system. If the nutrients, minerals or vitamins are not being absorbed well by small intestines then they will be excreted out of the body and will not be transported to the blood and other areas, this would result in deficiency of minerals and vitamins in blood that cause weakness.
Answer: Plato Answer
The fingerlike shape of the villi is very important for nutrient absorption because it increases the surface area of the small intestine. In celiac disease, the villi flatten, decreasing the surface area of the small intestine. As a result, fewer nutrients get absorbed. Also, the model shows that celiac disease damages the epithelial cells of villi. The epithelial cell layer is important for the diffusion of nutrients to the capillaries. Without a healthy epithelial cell later, fewer nutrients may be absorbed, and the body may not have enough energy to perform its functions.

Explanation:
A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Ee, Hh, and Bb, that determine if gremlins are evil (E), have hair (H), and biting teeth (B). In order to determine if the 3 genes were linked, a standard testcross was done, and the 1000 offspring ...
Answer:
The correct gene order is H-e-B
Recombination frequency between genes E and B = 10%
Explanation:
In linkage parental genotype is always in greater number than recombinants, hence:
400 = eeHhBb : Parental
426 = Eehhbb : Parental
Double crossovers have the smallest number hence:
EeHhBb = 4 : Double recombinant
eehhbb = 2 : Double recombinant
Double cross over places middle allele from one sister chromatid to other one. Hence a non parental allele of the middle gene is present with parental alleles of the flanking genes.
Here recombinant type is EHB and parental type is eHB . Only gene order H-e-B would result in double cross over which would give EHB and ehb double recombinants. Hence, the correct gene order is H-e-B.
Single crossover between gene E and B would result in Heb and hEB progeny ( 48 and 46 )
Recombination frequency between E and B = [(Double recombinants + Single E and B recombinants) / Total progeny)*100]
= [ (4 + 2 + 48 + 46)/1000] * 100
= 100/1000
= 0.1 * 100 = 10%
The light reactions of photosynthesis use chemiosmosis to produce ATP that will be used in the Calvin cycle. The electrochemical gradient that drives this chemiosmosis is formed across which structure(s)?
Answer: Thylakoid membrane.
Explanation:
Photosynthesis is a chemical process carried out by plants, algae, and certain microorganisms, whereby solar energy is captured and converted into chemical energy in the form of ATP and organic compounds. During electron transfer, the protons (H +) of the H atoms are sent to the interior of the thylakoids through their membranes, producing an energy gradient. This electrochemical gradient generates enough energy to phosphorylate ADP and produce ATP, similar to the oxidative phosphorylation that occurs in mitochondria. The end products are ATP and NADPH.
A common column material used in size-exclusion chromatography is dextran, a polysaccharide of glucose. Which type of interaction most likely occurs between proteins and the dextran column material?
Answer:
Hydrogen bonding
Explanation:
A hydrogen bond is a form of the electrostatic force of attraction which takes place between the hydrogen atom and a more electronegative atom such as nitrogen, fluorine, and oxygen. Hydrogen bond falls in the category of weak forces. In size-exclusion chromatography, the type of interaction that takes place between the proteins and dextran is hydrogen bonding. The hydrogen bonding is possible because dextran, being a polysaccharide of glucose has several hydroxyl groups and thus, they get involved in the hydrogen bonding.If a nearsighted person has a far point df that is 3.50m from the eye, what is the focal length f1 of the contact lenses that the person would need to see an object at infinity clearly?
Answer:
[tex]-3.50[/tex] meter
Explanation:
A nearsighted person uses concave lens.
Given -
Far point i.e distance of object [tex]= - 3.5[/tex] meter
Distance of image is not given . Hence we will assume that the image can be formed at any distance. We will take "di" [tex]=[/tex] infinity
As we know
[tex]\frac{1}{f} = \frac{1}{di} + \frac{1}{df} \\[/tex]
Substituting the given values in above equation, we get -
[tex]\frac{1}{f} = \frac{1}{infinity} + \frac{1}{-3.50}\\ \frac{1}{f} = 0 + \frac{1}{-3.50}\\ f = -3.50[/tex]
Hence, the focal length of the contact lens is equal to [tex]-3.50[/tex] meter

Which of the following is often provided by anthropologists and biologists as a possible explanation for the development of bipedal hominids?
A. Standing upright allowed for sightlines over tall grasses and savannah shrubbery
B. Standing upright allowed for better tree climbing
C. Standing upright allowed for more efficient movement
D. Standing upright allowed for better foraging of tree fruits
Answer:
The answer is C. Standing upright allowed for sightlines over tall grasses and savanna shrubbery
Hope this helps!!!
Please mark as brainliest:)
Answer:
The correct answer is option A-standing upright allowed for sightlines over tall grasses and savannah shrubbery.
Explanation:
Bipedalism or walking upright on two legs departed the hominids- Neanderthals and Homo erectus from four-legged apes. Many reasons were given to support the bipedalism of hominids like:
1. They needed to stand over tall grass to minimize the body exposure to the sun in savannah.
2. They needed to stand over tall grass to increase the sightlines to gather foods for themselves especially females and young ones which required hands to be free.
Thus, option A is the correct option.
