Answers

I think it’s D but not 100% sure.

The areas of high rainfall most likely to occur in " Above warm surface waters".

What is rainfall ?

The moist air would be forced to ascend whenever it encounters obstacles like mountains as well as rises as a result. Then condensation happens, and it starts to rain. Orographic rain and relief rain are two names for this sort of precipitation.

There are generally three types of rainfall occur:

reliefconvectional.frontal.

What is affected by natural selection?

Answers

Answer:

variation

Explanation:

Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of laboratory rats a daily diet of precisely 125.6 units of niacin and 5,400 units of retinol. She uses two types of commercial pellet food. Food A contains 0.86 units of niacin and 30 units of retinol per gram. Food B contains 0.66 units of niacin and 40 units of retinol per gram. How many grams of each food does she feed this group of rats each day

Answers

Answer:

- 100 grams of food A (x)

- 60 grams of food B (y)

Explanation:

According to this question, the group of laboratory rats are being fed a daily diet of:

- 125.6 units of niacin and 5,400 units of retinol

Let x represent the number of grams needed for food A.

Let y represent the number of grams needed for food B.

This means that:

Food A: Niacin = 0.86x, Retinol = 30x

Food B: Niacin = 0.66y, Retinol = 40y

Since there are 125.6 units of niacin fed to the rats in total, then;

0.86x (A) + 0.66y (B) = 125.6

Since there are 5400 units of retinol fed to the rats in total, then;

30x (A) + 40y (B) = 5400

Solving these two equations simultaneously using elimination method:

0.86x (A) + 0.66y (B) = 125.6 ........(eqn 1)

30x (A) + 40y (B) = 5400 ............ (eqn 2)

Multiply eqn 1 by 30 and eqn 2 by 0.86

30 × 0.86x + 0.66y = 125.6

0.86 × 30x + 40y = 5400

25.8x + 19.8y = 3768 ............ (eqn 3)

25.8x + 34.4y = 4644 ........... (eqn 4)

Subtract eqn 3 from eqn 4

14.6y = 876

Divide both sides by 14.6

y = 876/14.6

y = 60

Substitute value for y (60) into eqn 2

30x + 40y = 5400

30x + 40(60) = 5400

30x + 2400 = 5400

30x = 5400 - 2400

30x = 3000

x = 3000/30

x = 100

Therefore, she feeds the group of rats 100grams of food A (x) and 60 grams of food B (y).

Answer:

1. Hypothalamus

2. Optic chiasma

3. Corpora quadrigemina

4. Cerebellum

5. Thalamus

6. Medulla oblangata

7. Corpus Collosum

8. Fornix

9. Cerebral aqueduct

10. Midbrain

Explanation:

The hypothalamus is a small central region of the brain that regulates body temperature by responding to both internal and external stimuli and also produces the antidiuretic hormone (ADH) in order to trigger the reabsorption of water in the kidneys. The optic chiasma is a special sensory structure located along the visual pathway, directly in front of the hypothalamus, which is crucial to vision. The corpora quadrigemina, also known as quadruple bodies, are reflex centers located in the mesencephalon (midbrain) that regulate the position of the head and eyes in response to somatic stimuli.  The cerebellum is a part of the brain located behind the top part of the brain stem which is involved in motor movement regulation and balance control. The thalamus (massa intermedia) is a paired gray matter structure found near the center of the brain that plays vital roles associated with sensory and motor functions of the brain. The medulla oblangata (medulla) is a structure located at the base of the brain involved in the regulation of sensory, motor, and mental functions (e.g., breathing, pain modulation, etc). The corpus callosum (the callosal commissure) is a bundle of nerve fibers that connects the two hemispheres of the brain. The fornix (agenesis of the corpus callosum) is a large interhemispheric commissure that connects neurons in the right and left hemispheres. The cerebral aqueduct (aqueduct of Sylvius) is a narrow channel that connects the third and fourth ventricles, thus allowing the cerebrospinal fluid to flow between the ventricles. Finally, the midbrain o 'mesencephalon' is a small region located in between the forebrain and hindbrain, which is involved in auditory and visual processing, eye movement and coordination.

how proteins are made​

Answers

Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.  

After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.

Answer:

proteins are made of large numbers of amino acids joined end to end. The chains fold up to form 3d molecules with complex shapes - you could think of it as origami with very long and thin piece of paper

Explain E.O. Wilson's theory of Island Biogeography as it applies to environments other than islands physically
surrounded by water.

Answers

Answer:

The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.

It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.
