What is the difference between metaphase in mitosis and metaphase I in meiosis? How are they the same?

Vikki [24]

The difference between is metaphase in mitosis has ‘pairs of chromosomes’, while metaphase in meiosis have ‘spindle fibers’. They are the same because metaphase 2 is found in meiosis 2. The metaphase 2 in mitosis, chromosomes are arranged on the metaphase plate and are attached to the completed spindle.

I hope this helps

A student was observing slides of cell division. In one of the slides, he noticed loosely coiled chromatin depicting DNA duplica

soldi70 [24.7K]

Answer:

A. S phase

Explanation:

The cell cycle involves all the series of division events that occurs to an organism. Cell division, which can be meiosis or mitosis, involves two main stages viz: Interphase and M phase.

Interphase describes the resting stage of the cell i.e. when the cell is not dividing. The cell uses this time to prepare itself for the next round of division. Interphase stage further consists of three main phases viz: G1, S and G2 phases.

In the S phase or synthesis phase of Interphase, the cell duplicates its genetic material (DNA). Hence, an onion cell observed by a student to have loosely coiled chromatin depicting DNA duplication is in the S-PHASE.

To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called ho

Reptile [31]

Answer:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

A. Raising air temperature: Increase

B. Lowering air temperature: Decrease

C. Adding clothing: Increase

D. Exercising: Increase

Explanation:

The question is incomplete, it is necessary to look for a software related to this homework.

Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)

The Human Homeostasis Gizmo™ is a software that allows you to explore how the human body stays at a nearly constant temperature in different conditions. To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the final body temperature to the final body temperature while there is no specific movement or change.

Then:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

A. Raising air temperature: Increase

B. Lowering air temperature: Decrease

C. Adding clothing: Increase

D. Exercising: Increase

This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.

The effect of different factors on body temperature according to Gizmo:

A. Raising air temperature: Increase

B. Lowering air temperature: Decrease

C. Click Add to a sweatshirt, hat, pants, and parka. Then, adding clothing:

Maintained

D. Set the Exercise level to 70%, then exercising: Increase

When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.

Cell respiration begins with

irinina [24]

Answer:

Cell respiration begins with Glycolysis .

Explanation:

Glycolysis is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule of glucose(C6H12O6)through glycolysis. The NADH and ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.
