All matter, must contain

Answers

Answer 1
All matter must have mass and take up space
Answer 2

Answer: Mass and Space.

Any object that occupies space and has some weight or mass is called matter. All matter is made up of atoms. Matter can be of different types based on the type of atoms it is composed of. Mass, color, shape and size are some physical properties of solid state matter. The matter can be present in all three states of solid, liquid and gas but in every state it occupies space and has mass. Few things which are not considered to be matter are electricity, light, sound, heat etc.

which part of photosynthesis requires ATP, NADPH, and carbon dioxide to produce glucose

Answers

Final answer:

The Calvin Cycle or light-independent reactions of photosynthesis use ATP, NADPH, and carbon dioxide to produce glucose.

Explanation:

The part of photosynthesis that requires ATP, NADPH, and carbon dioxide to produce glucose is known as the Calvin Cycle, or the light-independent reactions. These reactions do not require light to occur and are responsible for the fixation of carbon dioxide into organic molecules. In the process of carbon fixation, CO₂ is 'fixed' from an inorganic to an organic form and then, using the ATP and NADPH generated from the light-dependent reactions, these fixed carbons are combined to form sugar molecules such as glucose.

C. the breeder performs the cross and finds half of the f1 progeny have black fur and half have white fur. what was the genotype of the mouse with black fur that she started with in the p0 generation?

Answers

The only way this works is if the 2 parents are both heterozygous for fur color. So each parent is Ff (I'm using F for fur color where F is black and f is white).

The two Ff parents would have had to come from two parents that had FF and ff as their genotypes (so a homozygous black mouse and a homozygous white mouse). 

You can check these by Punnet Square starting with the p0 generation and cross FF and ff; you get all Ff.
Then do another Punnet Square crossing Ff with Ff and you get 50% progeny Ff (black) and 50% ff (white).

Compare in general terms the effects of epinephrine glucagon and insulin on glucose metabolism

Answers

Epinephrine and glucagon cause an increase in the blood glucose level. Epinephrine acts when a higher than normal level of glucose is required; glucagon acts when the level is unusually low. Both stimulate gluconeogenesis and glycogen breakdown and decrease glycolysis and glycogen synthesis. Insulin causes a decrease in blood glucose levels; it acts by increasing glycogen synthesis, glycolysis, and glucose uptake by cells as well as by decreasing glycogen breakdown.

Which abnormal skin growth results from a virus?

freckles

moles

warts

jaundice

Answers

Warts are caused because of a virus called HPV
Final answer:

Warts are the abnormal skin growths that result from a virus. While freckles, moles, and jaundice are also skin conditions, they are not typically caused by a virus. Instead, each has different causes such as sun exposure, genetics, and high levels of bilirubin respectively.

Explanation:

The abnormal skin growth that results from a virus is a wart. Warts are rough, usually skin-colored growths that appear on the skin and mucous membranes. They are caused by the human papillomavirus (HPV). The virus infects the top layer of the skin and causes it to grow quickly, leading to a wart. While freckles, moles, and jaundice can also be familiar terms related to skin conditions, these are not typically caused by a virus.

For instance, freckles aren't caused by a virus but are small, brownish spots on the skin that can appear as a result of sun exposure and genetics. Moles, which are small skin marks caused by pigment-producing cells in the skin, are mostly harmless and aren't typically caused by a virus. Meanwhile, jaundice is a result of high levels of bilirubin in the body and causes a yellowing of the skin and eyes, but it is not related to a viral infection.

If the ductus deferens tubes are cut and tied (vasectomy), the semen will not contain select one:
a. fructose.
b. buffers.
c. mucus.
d. sperm.
e. all of these.

Answers

The correct answer is D. sperm

If the ductus deferens tubes are cut and tied, the semen will not contain sperms. This is known as vasectomy. This procedure is performed in males to control population. Thus, the correct option is D.

What is Vasectomy?

Vasectomy is the permanent male sterilization procedure. It is a surgical procedure which involves the cutting or sealing of the ductus deferens tubes which carries a man's sperm to permanently prevent pregnancy. It is usually carried out by giving a local anesthetic to the client, where the man is awake but could not feel the pain, and this procedure complete in about 15 minutes.

Once the tubes are cut, sperms cannot enter into the semen of man or out of the body. However, the testes do produce sperms, but the sperms die and absorbed by the body. A man who have undergone a vasectomy still produces the semen and is also able to ejaculate it. But, the semen contains everything except sperms.

Therefore, the correct option is D.

Which of these is a distinguishing abiotic feature of the Great Barrier Reef

Answers

The Great Barrier Reef in Australia is known as the largest coral reef in the world and the largest living thing on Earth where it houses countless species of sea animals. 

Its distinguishing or distinct abiotic feature is its shallow waters.

Sunlight is one of the most important factors in an ecosystem necessary for the organism's survival. The reef mostly has shallow waters so it is easier for the light to penetrate the water for the organisms to use. Even the reefs are visible from the outer space due to its shallow waters. 

Final answer:

The Great Barrier Reef's warm shallow waters and calcium carbonate skeletons secreted by coral organisms are key abiotic features of the ecosystem.

Explanation:

The Great Barrier Reef is the largest barrier reef in the world and a quintessential example of a marine ecosystem. One distinguishing abiotic feature of the Great Barrier Reef is its water temperature. The Great Barrier Reef exists in warm, shallow waters within the photic zone of the ocean, which is crucial for the coral organisms that form the reef. These organisms, colonies of saltwater polyps, secrete calcium carbonate skeletons which accumulate over time to form the structure of the reef. Therefore, the warm waters and the structure of the calcium-rich skeletons are significant abiotic features that contribute to the formation and maintenance of this underwater wonder.

Explanation:

Four Cell Organelles and Their Functions in Eukaryotic Cells

The eukaryotic cell is highly compartmentalized, with specialized structures called organelles, akin to a factory where each 'machine' or organelle has a distinct function. Here are four key organelles and their roles:

Nucleus: Functions like a safe, housing the genetic material (DNA) necessary for building proteins and governing cellular functions.Mitochondria: Known as the powerhouses of the cell, these organelles produce cellular energy, mainly in the form of ATP (adenosine triphosphate), through the process of cellular respiration.Vesicles: Small membrane-bound sacs that are involved in the transport of materials within the cell and to the cell membrane.Vacuoles: Storage centers within the cell, with plant cells possessing larger vacuoles for storing water and nutrients than animal cells.

These organelles are vital for the cell's functionality and survival, each enabling the cell to perform complex and specialized tasks, largely unparalleled by the more basic prokaryotic cells.

Which condition feeds a tropical storm as it develops into a hurricane? A. heat and moisture B. cool temperatures and rain C. high temperatures and freshwater D. wind and dry air

Answers

A. heat and moisture

Hurricanes form over tropical waters (between 8 and 20 degrees latitude) in areas of high humidity, light winds, and warm sea surface temperatures [typically 26.5 degrees Celsius (80 Fahrenheit) or greater]. These conditions usually prevail in the summer and early fall months of the tropical North Atlantic and North Pacific Oceans, and for this reason, hurricane “season” in the northern hemisphere runs from June through November.


The first sign of hurricane genesis (development) is the appearance of a cluster of thunderstorms over the tropical oceans, called a tropical disturbance. Tropical disturbances generally form in one of three ways, all of which involve the convergence of surface winds. When winds come together (converge), the force of the collision forces air to rise, initiating thunderstorms.

Identify whether each circumstance provided will promote an increase or decrease in blood pressure

Answers

Circumstance that cause an increase in Blood Pressure:

- increasing levels of aldosterone ((influences the reabsorption of sodium and excretion of potassium in the kidneys. This will indirectly influence the blood pressure since the volume of blood will change)

- vasoconstriction ( blood vessels increase their contraction, which equals to more pressure)

-increased release of renin (Converts angiotensinogen, secreted in the liver, into angiotensin I).
- increased activity of Angiotensin-converting enzyme ( this enzyme converts angiotensin I into angiotensin II increasing vasoconstriction).

Circumstances that cause a Decrease in Blood Pressure:

- decreased sodium reabsorption ( by decreasing sodium, the amount of water will also decrease or , in other words,will be excreted. Less water, will decrease volume of blood and that means less blood pressure)

- vasodilation (The smooth muscle in the blood vessels decrease their contraction, which equals to less pressure)

- declining levels of ADH(ADH is produced in the hypothalamus and stimulates vasoconstriction plus it promotes water reabsorption in the kidneys. To reduce blood pressure, is important to have ADH levels reduced)

Answer:

Option C,  is a good insulator

Explanation:

See the attached image of the  underwear

Solution

As it is clear in the image, the fabric of the underwear is poly fabric which acts as a good insulator.  

Being an insulator, it can easily trap the heat of the body during winters and does not allow this heat to escape due to which it is successful in keeping a person warm during the winters.  

If the material of the underwear would have been a conductor, it would have allowed heat of the body to escape.
