Answer:
A. Blood vessels in the skin narrow and contract.
Explanation:
If we will step outside without a coat on a snowy day then our blood vessels in the skin will become narrow and contract. It is a mechanism to conserve heat within our body in cold weather. If the blood vessels in the skin will become narrow and contract then less blood will flow in the blood vessels, this phenomenon is known as vasoconstriction. The blood of our body is warm but the exposure to the cold weather will cause the heat of the blood to dissipate into the environment. But constricted blood vessels will have less blood and hence heat loss is minimized which keeps the internal temperature of the body as normal even if outside environment is cold.
Answer:
A. Blood vessels in the skin narrow and contract.

When electrons flow along the electron transport chains of mitochondria
a. the ph of the matrix increases
b. ATP synthase pumps protons by active transport
c. the electrona gain free energy
d. NAD is oxidized
Answer: a. the ph of the matrix increases
Explanation:
NADH and FADH2 molecules resulting from the Krebs cycle (by reducing respectively NAD + and Electron and proton carriers (e- and H +), are oxidized in the final reactions of cellular respiration, and the electrons and protons are captured by oxygen, the final acceptor. The flow of electrons along the respiratory chain causes the active transport of protons along the chain through the inner membrane of the mitochondria. Protons return to the mitochondrial matrix by diffusion - chemiosmosis - and at the same time, ADP undergoes oxidative phosphorylation forming ATP. Because of this movement of protons inside the matrix, the ph of the matrix increases.
In the mitochondrial electron transport chain, ATP synthase uses proton gradient energy for ATP synthesis; electrons' energy decreases; NAD is oxidized; the pH of the matrix does not necessarily increase.
Explanation:The electron transport chain in mitochondria is part of the cellular respiration process during which energy is extracted from molecules such as glucose and transferred to other molecules (such as ATP, the main energy currency of the cell), a process that involves the flow of electrons. Here's what happens:
a. The pH of the matrix does not necessarily increase. The matrix contains a higher concentration of protons when the electron transport chain is active, which would actually decrease pH (meaning it becomes more acidic).b. ATP synthase does not pump protons, but it does utilize the energy from the flow of protons (down their gradient) to synthesize ATP from ADP and Pi (inorganic phosphate). This is known as chemiosmosis.c. Electrons don't gain free energy. The energy of the electrons is actually decreased as they are passed along the electron transport chain, and this energy is used to pump protons into the intermembrane space, creating a proton gradient.d. NAD is indeed oxidized, it loses its electrons to the first complex of the chain, becoming NAD+.Learn more about electron transport chain here:https://brainly.com/question/24368622

The male trees of a plant with vascular tissue and cones have multiflagellated sperm. The female trees produce rotten-smelling fleshy seeds that contain butyric acid. Which of the following is the most logical conclusion about the classification of this plant?
a. It belongs to the phylum Coniferophyta.
b. It belongs to the phylum Cycadophyta.
c. It belongs to the phylum Gingkophyta.
d. It belongs to the phylum Gnetophyta.
Answer: C. Phylum Gingkophyta.
Answer:
c. It belongs to the phylum Gingkophyta.
Explanation:
The tree in question is Ginkgo biloba, a tree belongs to the phylum Gingkophyta. It is a conifer. This species is the last species of this phylum, so often Ginkgo is called as ‘living fossil’. The male plant bears the male cone which produces multiflagellated sperms. Since it is a memebr of gymnospserm, it has well developed vascular tissue. The female trees produce fruits. The fruits emit very bad smell when left on the ground to rot. The rotting fruit releases butyric acid from the fleshy fruit wall sarcotesta.
Purple flowers are dominant to white flowers in pea plants. A gardener mates a purple plant with a white plant and records the offspring as having all purple flowers. The gardener just performed a(n) ________ and determined that the purple plant’s genotype was _________________
Answer:
The gardener performed hybrid crossing and the purple plant's genotype is: PP
Explanation:
Since we know the offspring's phenotype (appearance) is purple, the genotype can either be PP or Pp. We know that the farmer crossed a white plant, we can denote it's genotype as pp and a purple plant with a dominant trait. Because the farmer crossed the white plant with the purple plant, this tells us that the genotype of the purple plant must be PP.
Purple flowers are dominant to white flowers in pea plants. By performing a monohybrid cross and observing all purple offspring, the gardener determined that the purple plant's genotype is PP.
Explanation:The gardener performed a monohybrid cross by mating a purple plant with a white plant. Since all the offspring had purple flowers, we can conclude that purple flowers are dominant. Therefore, the purple plant's genotype must be homozygous dominant for the purple flower color, which is represented as PP. This is because, even when crossed with a plant possessing the recessive white flower color (pp), all the offspring expressed the dominant purple flower color, meaning the purple parent must have had two dominant alleles to pass on.

Can mold grow inside of chocolate
Answer:
It is is almost impossible for chocolate to mold as it doesn't have any moisture, required for mold growth.
There are two types of bloom:
Sugar bloom -- wipe the chocolate with a wet finger, it will dissolve.
Fat bloom -- wipe the chococolate with a dry finger, it will feel waxy or greasy
Either tends to look like a chalky coating, not very thick, definitely not fuzzy (like mold).
Yes, mold can grow inside chocolate if it is exposed to warm, humid or damp conditions. It is important to store chocolate properly to avoid mold growth, as some molds produce harmful mycotoxins.
The answer is yes, mold can potentially grow inside chocolate under certain conditions. Molds are microscopic fungi that can grow on various foods, including fruits, vegetables, meats, and dairy products, and they can appear as a gray or green "fur."
In particular, chocolate that has been exposed to warm, humid, or damp conditions may become a breeding ground for mold. Although chocolate is less likely to mold than many other foods because of its low water activity, if moisture is introduced or the storage conditions are poor, mold growth is possible.
This is why maintaining proper storage conditions for chocolate is important to prevent mold contamination.
Some molds that grow on food can produce dangerous mycotoxins, which are harmful if ingested, leading to allergic reactions, respiratory problems and even toxic effects. It's critical to discard any chocolate that shows visible signs of mold to avoid health risks.

Ordinary cell division produces two daughter cells that are genetically identical. This type of cell division is important for all of the following functions EXCEPTA) growth of a multicellular organism.B) cell replacement.C) production of sperm and eggs.D) asexual reproduction.
Answer:
C) production of sperm and eggs
Explanation:
Sperms and eggs are the male and female gametes respectively. Formation of sperms and egg cells require meiotic cell division. Meiosis in sperm mother cells and egg mother cells reduces the chromosome number of half in the sperms and eggs. Meiosis also adds new gene combinations in these gametes by the process of crossing over.
Mitosis cannot reduce the chromosome number to half in the sperms and eggs. Absence of crossing over in mitosis leads to the formation of genetically identical progeny cells from mitosis.
Hence, mitosis can not form sperms and egg cells. If it does, the sperms and egg cells would not have genetic variations and there would be doubling of chromosome number with each round of sexual reproduction.
Mitosis is necessary for the growth of multicellular organisms, cell replacement, and asexual reproduction. However, it does not play a role in the production of sperm and eggs, which is conducted through Meiosis.
Explanation:Ordinary cell division produces two daughter cells that are genetically identical through a process known as mitosis. This process is fundamental for the growth of a multicellular organism, cell replacement in tissues throughout the body, and asexual reproduction in some organisms. However, when it comes to the production of sperm and eggs, a different kind of cell division occurs known as meiosis. Meiosis produces cells that are not genetically identical, therefore cell division via mitosis does not play a role in the production of sperm and eggs.

b. Adolescence (ages 13-17):
c. Transitional Adulthood (ages 18-29):
d. The Middle Years (ages 30-65):
e. The Older Years (ages 65 and above):
Answer:
During their childhood, kids learn about the world that surrounds them when going through 3 different phases regarding their body parts, and taking contact with their family and school; when puberty strikes, the learning shifts towards the teen's peer group and their chosen role models to create new patterns in behaviour and find themselves (adolescence). Once the individual enters adulthood and establish his/her personality, can form strong and intimate relationships with friends and romantic partners (transitional adulthood). When reaching the middle years, the person needs to contribute to society in some way to feel productive, like raising children or helping his/her community. Finally, during the older years, humans tend to reflect on their lives and accomplishments to develop a sense of either integrity or despair.
This study is replicated in the Appalachian Mountains with similar results. Which of the following is true? The number of days with poor flower availability increased. The number of days with poor flower availability decreased. Flower availability fluctuated wildly. There was no change in the number of days with poor flower availability.
Answer:
There was no change in the number of days with poor flower availability
Explanation:
When replicating a study, the researcher develops the exact same study (experiment/treatment) in different places (experimental unit). In this case, as the researcher replicates the study in the Appalachian Mountains and gets similar results, that means that there was no change in the number of days with poor flower availability.
The impacts of climate change on the timing of flowering in plants can affect their availability to insect pollinators. But without specifics from the related study in the Appalachian Mountains, it's impossible to say whether days with poor flower availability increased, decreased, remained the same or fluctuated.
Explanation:The answer to whether the number of days with poor flower availability increased, decreased, fluctuated, or didn't change based on a study replicated in the Appalachian Mountains isn't provided in your question. However, studies show that temperature and precipitation, which are impacted by climate change, play crucial roles in the geographic distribution and phenology of plants and animals. As seen in Great Britain, climate change can cause plants to flower earlier than in previous years.
This is pertinent because if the insect pollinators don't emerge earlier in sync with the flowers, there could be harmful ecosystem effects as a result of this mismatch of timing. Consequently, there might be days of poor flower availability for these insects. But without specifics pertaining to the study in the Appalachian Mountains, a definitive answer can't be given.

If humans did not breathe in O2, we would not _____. make enough ATP to meet our energy requirements have enough enzymes to catalyze reactions be able to synthesize organic molecules from inorganic molecules be able to perform lactic acid fermentation be affected because we can switch to alcoholic fermentation
Answer: If humans did not breathe in O2, we would not make enough ATP to meet our energy requirements
Explanation:
During the last step of aerobic cellular respiration, the respiratory chain where oxidative phosphorylation occurs, most of the ATP generated in cellular respiration occurs. This step is coupled with the reoxidation of the NADH and FADH2 molecules, which become NAD + and FAD, respectively. In this reoxidation, high energy electrons are released which, after losing their excess energy, reduce the oxygen gas to water molecules. The energy released gradually by the electrons during their transfer to the oxygen gas is used in the production of ATP.
Final answer:
Without oxygen, humans would not be able to produce enough ATP to meet energy requirements efficiently, as they would have to rely on less efficient processes such as lactic acid fermentation instead of aerobic respiration.
Explanation:
If humans did not breathe in O2, we would not make enough ATP to meet our energy requirements. Oxygen is crucial for aerobic cellular respiration, a metabolic process that produces a significant amount of ATP by breaking down glucose in the presence of oxygen. When oxygen is not available, cells resort to fermentation to produce ATP, but this process yields significantly less ATP compared to aerobic respiration.
Fermentation, such as lactic acid fermentation, allows for the continued production of ATP in the absence of oxygen by converting pyruvate into lactate. This process is crucial during situations where oxygen supply is limited, such as during intense exercise. However, it is not as efficient in meeting the body's energy demands as aerobic respiration. With a limited oxygen supply, the human body could not sustain high energy needs over extended periods, impacting many biological functions.
Moreover, aerobic respiration enables the complete breakdown of glucose molecules, yielding up to 36-38 ATP molecules per glucose molecule, as opposed to only 2 ATP molecules per glucose molecule via glycolysis in fermentation. This vast difference underscores the essential role of oxygen in efficiently meeting the body's energy requirements.

Within a particular population, darkly colored rats are more likely to survive than more lightly colored individuals. This situation is likely to result in a. directional selection. b. stabilizing selection. c. disruptive selection. d. balancing selection.
Answer:
a. directional selection
Explanation:
Directional selection is a type of natural selection wherein one extreme trait is favored and the individuals with that extreme trait are at survival and reproductive advantage.
In the given example, dark-colored rats are favored by natural selection over the light-colored rats. This occurs because the rats with dark skin color have better survival rats in the prevailing surrounding. Since one extreme trait (dark skin color) is favored over the other (light skin color), the rat population is undergoing directional selection.

Someone who is HIV positive and takes his/her arvs in time which led him to test when results shows negative. Can he transmit the virus to a partner who is negative?
Answer:
I believe the answer is No.
Explanation:
HIV is a virus which lacks the mechanism to reproduce since it is just an enclosed bunch of genetic material. With that in mind, it requires a mechanism to survive and reproduce and for that it targets the T-lymphocytes since the cells have receptors for the virus. It starts its cycle by attachment, penetration, biosynthesis, maturation and lastly budding. It adds it's genetic material to the DNA chains in the nucleus which the human cells replicate unknowingly. Most of the anti-retrovirals target to prevent this replication through targeting enzymes such as protease inhibitors. Taking of the drugs only reduces the replication of the virus lowering the viral count to less than 200 where we cannot count them anymore because they are widely distributed. Having a viral count <200 does not mean you are free of the virus but only that it is very low to be counted or cause significant health problems but the small number can still be transmitted if protection is not used.

5. Myofibrils
6. Myofilament
7.Thick filament
8. Thin filament
Explanation:
These are all parts of the skeletal muscle and they are all involved in the contraction of your muslces.
The sacrolemma is also known as the myolemma. It is a specialized plasma membrane of the skeletal muscle cell. It is an excitable membrane that shares similarities to the cell membrane of a neuron cell.
The T-tubule extends from the sarcolemma to the sarcoplasmic reticulum (SR). This is the smooth endoplasmic reticulum of the muscle cell. When the sarcolemma gets excited, it triggers the SR to release the calcium ions stored in it. The release of Calcium ions triggers the contraction of myofilaments.
There are two types of myofilaments, the thick myofilament and the thin myofilament. These myofilaments contain contractile proteins, actin and myosin. Thick myofilaments contain myosin where one thick myofilament contains 300 myosin molecules. Thin myofilaments contain contractile and regulatory proteins. These myofilamens make up myofibrils.
