<em>Answer 1: Stress is defined as a force that can cause a change in an object or a physical body while strain is the change in the form or shape of the object or physical body on which stress is applied.</em>

<em>Answer 2: Stress can occur without strain, but strain cannot occur with the absence of stress.</em>

While stress is a type of pressure given by force acting per unit area. Strain is the ratio of change in length and total length when stress occurs. Ratio of stress and strain gives Young's Modulus. The curve between stress and stress is linear as long as they are proportional to each other.

Condensation often gathers in the bottom of agar slants. why is it important in this exercise to limit condensation on plates bu

vekshin1

<h2>Answer:</h2>

Because condensation on the slant effects the bacterial growth in the test tube.

<h3>Explanation:</h3>

When agar is solidify in the test tube tilted, it takes a shape of slide on one side of the tube which is known as slat.
Slant is used instead of petri dishes because they provide more surface area for growth.
Water in the slat can invade the test tube, making agar unstable and the bacterial growth on the slat will be affected by moisture in bottom of slant.
In petri dishes, it is no big problem of moisture condensation.

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.

tatuchka [14]

Human anatomy deals with the study of the human body, its structures, and how these structures specifically function. Microscopic anatomy on the other hand deals with structures found within the body that cannot be seen by the naked eye but can be viewed with the use of the microscopic. Microscopic anatomy deals with the study of the smallest structures of the cells, tissues, and organs of the body.
