In an experiment to determine whether M phase cells contain a regulatory molecule that initiates mitosis, cytoplasm from M phase

cells and interphase cells was injected separately into interphase cells. Why did researchers inject cytoplasm from interphase cells

Answer:

As a negative guide, to demonstrate that perhaps the injection itself has no impact on the cell cycle.

A successful experiment has handled the same control group as the experimental group with the exception of the variable being examined, in this case the cytoplasm M-phase.

Therefore, Wendy's genotype must be bb and her father's must be Bb. 

The genotype is your total heritable hereditary character; it is your one of a kind genome that would be uncovered by individual genome sequencing. In any case, the word genotype can likewise allude just to a specific quality or set of qualities conveyed by a person. For instance, in the event that you convey a change that is connected to diabetes, you may allude to your genotype just as for this transformation without thought of the various quality variations that you may convey.

Organisms convert chemical energy into other types of energy in order to perform certain functions. Match each function to the t
Rama09 [41]

<u>Answer</u>: Thermal energy---->  a polar bear breaks down stored fat to increase its temperature.

Mechanical energy-------> bat emits and receives sounds to locate prey.

Electrical energy------>eel releases a current to defend itself.

Radiant energy -------->  a firefly produces a green glow from its abdomen to attract mates.

<u>Explanation</u>:

  • <em>Thermal energy</em> is the energy created in the movement of particles that leads to the production of heat and thus, the temperature increases. Since the polar bears break down fat to increase temperature, the energy generated is thermal energy.  
  • The<em> mechanical energy</em> is defined as the sum of energy of motion and   the position of an object  . Thus the energy produced by the bat to locate its prey is mechanical energy.
  • The energy associated with the production of electromagnetic radiation is<em> radiant energy,</em> thus the glow produced by fireflies is a form of radiant energy.
  • The energy produced due to the movement of electrons is electrical energy. Thus, the energy produced by an eel in the form of electric current is <em>electrical energy.</em>

(Q002) Review the vertebral column and individual vertebrae from Exercise 3 (p. 166 of your lab manual). What similarities and d
Alexandra [31]

Answer and Explanation:

1. The biggest similarity between the main types of vertebrae is the location where they are found since they are all established on the body's back, precisely on the midline of the back. The main differences, on the other hand, are related to the size and weight of each of them.

2. The similarities exist because all the vertebrae have to promote the support of the body, the back being the most appropriate place for them to establish themselves.

3. The differences are related to the function and type of support that each vertebrae promotes, the higher the level of systemization, the larger and thicker the vertebrae must be.

4. The caudal vertebrae should be similar to the vertebrae of the coccix, since a tail would be a representation of elongation of the coccix. We can reach this conclusion through the analysis of images that promote the visualization of this area of the body.
