Answer:

Prokaryotic cells have a ring-shaped nucleus, however it is not fully defined, and thanks to this, their DNA is found unlike eukaryotic cells, scattered in the cytoplasm, an example of a prokaryotic cell is a bacterium, which has Oval shaped

Why is it important to have MET at the beginning of mRNA?

astra-53 [7]

The Beginning of mRNA Is Not Translated
Interestingly, not all regions of an mRNA molecule correspond to particular amino acids. In particular, there is an area near the 5' end of the molecule that is known as the untranslated region (UTR) or leader sequence. This portion of mRNA is located between the first nucleotide that is transcribed and the start codon (AUG) of the coding region, and it does not affect the sequence of amino acids in a protein (Figure 3).

So, what is the purpose of the UTR? It turns out that the leader sequence is important because it contains a ribosome-binding site. In bacteria, this site is known as the Shine-Dalgarno box (AGGAGG), after scientists John Shine and Lynn Dalgarno, who first characterized it. A similar site in vertebrates was characterized by Marilyn Kozak and is thus known as the Kozak box. In bacterial mRNA, the 5' UTR is normally short; in human mRNA, the median length of the 5' UTR is about 170 nucleotides. If the leader is long, it may contain regulatory sequences, including binding sites for proteins, that can affect the stability of the mRNA or the efficiency of its translation.

The myocardium receives its blood supply from the coronary arteries. True or False

Cerrena [4.2K]

Answer:

The statement is true.

Explanation:

The myocardium is the muscle tissue of the heart, a muscle responsible for pumping blood through the circulatory system through contraction. It receives a part of the large volume of blood that passes through the atria and ventricles. A system of arteries and veins (coronary circulation) provides the myocardium with oxygen-rich blood and allows the return of venous or oxygen-poor blood to the right atrium. The right coronary artery and the left coronary artery are the branches of the aorta responsible for the blood supply.

An infant is admitted to the nursery after a difficult shoulder dystocia vaginal birth. which condition should the nurse careful

Luda [366]

<span>The nurse should assess the baby for a brachial plexus injury such as brachial plexus paralysis because this is the number one injury caused by a shoulder dystocia vaginal birth. This type of birth produces pressure and traction on the brachial plexus. Sometimes the injury caused during this type of birth are only temporary, but other times they are permanent.</span>

The portion of the tubule system that is relatively impermeable to solutes but contains many aquaporins for water reabsorption

topjm [15]

Descending limb of loop of Henle

It helps to maintain the concentration of urine. It is highly permeable to water thus water is readily reabsorbed from the descending limb by osmosis. It is impermeable to sodium and chloride ions.

<h3>What is a Tubule system ?</h3>

The transverse tubular system is a network of interconnecting rings, each of which surrounds a myofibril

The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion. These apply to numerous substances

The distal convoluted tubule (DCT) and collecting duct (CD) are the final two segments of the kidney nephron. They have an important role in the absorption of many ions, and in water reabsorption.

Science fusion grade 7 lesson 1 review

4) The simplest type of response is a direct one-to-one stimulus-response reaction. A change in the environment is the stimulus; the reaction of the organism to it is the response. In single-celled organisms, the response is the result of a property of the cell fluid called irritability.

5) During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes. Gametes contain half as many chromosomes as the other cells in the organism, and each gamete is genetically unique because the DNA of the parent cell is shuffled before the cell divides.

6)Producers can make their own food by capturing the sun's energy, but consumers and decomposes can't. Consumers need to eat other organisms to obtain energy. Decomposes are like the recycles of nature. They obtain energy for their own needs while returning simple molecules to the environment.

7)The birds are growing up into a larger bird.

8) Cells manage a wide range of functions in their tiny package growing, moving, housekeeping, and so on and most of those functions require energy. But how do cells get this energy in the first place? And how do they use it in the most efficient manner possible?

9)Aside from the fact that fish,and trees can be aged in similar ways (by counting annual growth rings), new research shows that all three also respond to climate change in similar ways.

10)No we will not be able to survive cause there is no food or water and it is only oxygen of course you will be able to breathe but not eat or drink.
