mario62 [17]

Answer:

D. Pool temperature

Explanation:

The dependent variable in an experiment is the variable that is measured or responds to another variable called the independent variable. The outcome of the dependent variable is dependent on the independent variable.

In this computer model, the engineers compare which of several pool designs require the least amount of energy to be heated. The TEMPERATURE at which each pool design is heated is dependent on the type of pool design used. Hence, POOL TEMPERATURE is the dependent variable. It is the variable being measured in response to the type of pool design used.

During the translation of mRNA molecules, the new polypeptides are often directed to specific parts of the cell by the presence
LuckyWell [14K]

Answer:

B. an amino terminal signal peptide

Explanation:

The reactions of the citric acid cycle occur in the matrix of mitochondria. Therefore, all the enzymes required for this pathway are present in the matrix of mitochondria. These enzymes are formed on the ribosomes present in the cytosol and are transported into the mitochondria with the help of cytosolic heat shock proteins. The newly formed mitochondrial proteins have signal sequences present at their N terminal. The proteins to be transported into the matrix have a single signal sequence that at N terminal which is removed by a protease once the enzyme enters into the matrix.

What are 5 major functions of your skeleton?
Goryan [66]
1. it <span>supports muscles and tissue

2.it also </span><span>protects the vital organs

3. </span>The skeleton gives the body its shape, which changes with growth. In addition to determining characteristics such as height and the size of the hands and feet, stable body shape enables essential functions. For example, a stable rib cage and spine enable the lungs to fully inflate when breathing. Conditions such as osteoporosis of the spine and broken ribs can alter the shape of the chest and impair this vital body function.

5.Larger bones contain bone marrow, a spongy tissue inside the bones. There are two main types of marrow, red and yellow. Red marrow is responsible for production of all of the body's red blood cells and many of its white blood cells. Red blood cells are produced at an average rate of approximately 200 million per day. These cells carry life-sustaining oxygen to the body tissues.


In adults, red marrow is found primarily in the breastbone, hips, ribs, skull, spinal bones and at the end of long bones of the arms and legs. Several types of white blood cells, which protect the body from infections, are also produced in red bone marrow. Yellow bone marrow contains primary fat cells but can transform into red marrow if the body needs to increase blood cell production, such as if anemia develops

What kind of organism is a heterotroph?
Harman [31]
<span>These organisms are called autotrophs. Autotrophs are also called 'self-feeders,' and they are able to produce energy from sunlight and carbon dioxide and are therefore known as 'producers.' The only autotrophs that we know of are plants and some types of algae. This makes all other organisms heterotrophs</span>

The gray matter of the two halves of the thalamus is divided by a vertical sheet of white matter called the__________.
Firdavs [7]

The gray matter of the two halves of the thalamus is divided by a vertical sheet of white matter called the internal medullary thalamus.

On cross sections of the thalamus, layers of myelinated fibres are seen as medullary laminae. They are also known as medullary layers of the thalamus or laminae medullares thalami. The thalamus is divided into lateral, medial, and anterior regions by the internal medullary lamina, a thin, vertical strip of white matter that bifurcates in its anterior portion.

The intralaminar nuclei are enclosed by the laminae medullaris medialis (interior medullary lamina), which is located between the dorsomedial and ventral nuclei of the thalamus (centromedian nucleus, paracentral, and central lateral).

Therefore, gray matter of the two halves of the thalamus is divided by a vertical sheet of white matter called the internal medullary thalamus.
