D. chemical bonds between reactants.

In a chemical reaction, the reactants break and establish new bonds between atoms by exchanging electrons. The overall atomic mass doesn't change. Element identities only change with a loss or gain of protons, which happen in nuclear reactions. The total number of electrons does not change, just become exchanged or shared between atoms.

Answer:

B

Explanation:

Homeostasis is defined as a regulating process to maintain balance within the body systems. It is to maintain the interior conditions and ensure that nothing goes wrong or out of the ordinary. Choice B matches this.

A is incorrect because homeostasis can occur <em>both</em> at the cellular level <em>and</em> at the system level.

C is incorrect because homeostasis actually occurs in prokaryotes, as well.

Part A: If one follows 70 primary oocytes in an animal through their various stages of oogenesis, how many secondary oocytes wou
olga nikolaevna [1]

Answer:

<u>Part A</u> : 70 secondary oocytes will be formed.

<u>Part B</u> : 70 first polar bodies will be formed.

<u>Part C</u> : 70 ootids will be formed.

Explanation:

During oogenesis growth maturation of a single oogonium produces one primary oogonium.

the primary oogonium then undergoes meiosis -1 and produces  one secondary oocyte and first polar body.

The secondary oocyte then undergoes meiosis - 2 and forms an ootid and second polar body.

The ootid then differentiates into the ovum.

As in the above scenario , 70 primary oocytes are present , they undergo meiosis-1 and produces 70 secondary oocytes and 70 first polar bodies. Hence answers of part A and B is 70.

As 70 secondary oocytes are formed , they undergo meiosis -2 and forms 70 ootids which then differentiate in 70 ovums.
