a cell in g2 before meiosis begins, compared with one of the four cells produced at the end of meiosis ii, has

Diploid cell. In meiosis I, the cell undergoes cell division process that is more likely has the similar procedures that mitosis undergoes. The cell produced is called the diploid cell which has the complete 48 strands of chromosomes within it. However, after the mitosis II takes place, the cell produced is called a haploid cell which has only 24 chromosomes instead of 48.

g Indicate true (T) and false (F) statements below regarding cytokinesis in animal cells. Choose the correct answer represented

frozen [14]

<h2>Cytokinesis in animal cells</h2>

Explanation:

The force for cytokinesis is generated by kinesin motors on microtubule bundles that form the contractile ring:This statement is false because cytokinesis in animal cells starts with the assembly of contractile ring,contractile band consists of actin and myosin(microfilaments) which catalyse cleavage furrow formation
As the contractile ring constricts, its thickness increases to keep a constant volume:This statement is false because thickness remains constant
The midbody forms from bundles of actin and myosin: This statement is false because contractile ring forms bundles of actin and myosin whereas midbody is formed from microtubules
Local activation of Ran GTPase triggers the assembly and contraction of the contractile ring:This statement is false because local activation of Rho mediates profilin binding to actin and helps in assembly and contraction of contractile ring

The four letter string comes out to be FFFF

Which of the following scenarios would be most likely to cause a weak point in the aorta to rupture, and why? (2 points)

REY [17]

<span>I believe the answer is,

High systolic, because when the heart pumps, the pressure inside the aorta would be greatest, causing the weak spot to rupture outward.

This indicates high blood pressure that causes rupture of the aorta or aorta dissection.</span>

Brut [27]

Answer:

b. the 20 amino acids found in proteins differ in the composition of their R groups, which may be either polar or charged.

Explanation:

Since the proteins are polymers joined by a big number of amino acids, all the joins occur the same way because in all the amino acids there is always one part that is exactly the same in all of them.

The rest of the molecule in the amino acids, the R group, is different in each one, that is the characteristic of each one, and this is the part that can give the name and some other chemical properties.

The ________ is the site where lipids, triglycerides, and steroids are synthesized, as well as where calcium is stored within th

Ulleksa [173]

Answer:

smooth endoplasmic reticulum

Explanation:

Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.

Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.
