E
The E site or the Exit site, is the third binding site for
t-RNA in the ribosome during protein synthesis. It is accompanied by the second binding site
which is the P site (Peptidyl) and the first binding site which is the A site
(Aminoacyl).
Crossing over occurs during prophase . This is important because it increases genetic variation.
When the heart contracts, called systole, blood pressure increases. When the heart relaxes, called diastole, blood pressure decreases. Systole phase or contraction is started by the electrical cells of the sinoatrial node. The diastole phase is the period when the heart relaxes after contraction.<span> </span>
Answer:
b. 8P+ , 10no , 8e-
Explanation:
An isotope is a form of a chemical element whose atomic nucleus of an element contains a specific number of neutrons and protons. For example, the nucleus of a carbon atom contains 6 neutrons(no) and 6 protons(P+) and similarly in the nucleus of oxygen contains 8 neutrons and 8 protons . The number of neutron can varies in the nucleus of that element. Variation in neutrons form isotopes of the element. In nature, oxygen has three stable isotopes, ¹⁶O, ¹⁷O, and ¹⁸O, but ¹⁶O most abundant. The ¹⁸O isotope of oxygen contains 8 protons(P+), 8 electrons(e-) and 10 neutrons(no) instead of normal 8 neutrons.
A worm that is solid from the gut epithelium to the outermost epithelium would be considered acoelomate.
<h3>What animal is acoelomate?</h3>
Acoelomate Examples
Examples of acoelomates are seen in the kingdom Animalia and the class Platyhelminthes.
Generally known as flatworms, these spineless animals are unsegmented worms with bilateral symmetry.
Thus, A worm that is solid from the gut epithelium to the outermost epithelium would be considered acoelomate.
