Please explain how treadmilling contributes to actin-based motility in crawling cells. Be specific in why both actin filament growth and shrinkage are necessary.

Answers

Action needs ATP. ATP is the coenzyme, which is used by the cells to transfer energy to the cell when a muscle cell demands energy to contract. ATP is short for Adenosine Triphosphate and is critical for muscles to contract. APT prepares the myosin to bind with actin - it moves the myosin to a high energy state ready to move. The myosin is the protein that converts the chemical energy, ATP, into mechanical energy. This cycle keeps on repeating itself and the muscle expands and contracts. 

A human male with the chromosome constitution of XXXYY would contain how many Barr bodies in his somatic cells?

Answers

Answer:

2 Barr bodies

Explanation:

A Barr body is an inactive X chromosome. The inactive X chromosome is transcriptionally inactive. They derive their name from Murray Barr who discovered them

The Barr bodies are usually visible in humans with more than one X chromosome at interphase during cell division.

For a human male with the chromosome XXXYY, there will be 2 Barr bodies since he has 2 extra X chromosomes.

Anthony is studying how quickly children tire based on the amount of sugar they ingest. He splits a group of 20 children into 2 groups. One group is given sugar and the other is not. Anthony asks the children to start playing at a playground at the same time, and to stop when they tire, measuring the time each child stops playing. He finds that the children who did not ingest sugar played 2 minutes longer than those who did ingest sugar. Anthony rerandomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Anthony conclude the difference is significant?A: Yes Anthony can conclude the difference is significant because a 2-minute difference is not likely to happen by chance
B: No, Anthony cannot conclude the difference is significant because a 2-minute difference is likely to happen by chance.
C: Yes, Anthony can conclude the difference is significant because 0.25 is the difference in means that occurs most often.
D: No, Anthony cannot conclude the difference is significant because 0.25 is the difference in means that occurs most often.

Answers

I think the correct answer from the choices listed above is option C. Based on the data, Anthony can the difference is significant  because 0.25 is the difference in means that occurs most often. Hope this answers the question. Have a nice day.

Answer:

Option C,  Anthony can conclude the difference is significant because 0.25 is the difference in means that occurs most often.

Explanation:

Level of significance measures the unlikeliness in a hypothesis's against the measured reading.

0.05 is a common level of significance which depicts that there are 5% chances of a  type I error thereby rejecting a true null hypothesis in a one way test.

In two way test it depicts that there are 2.5% chances of a  type I error thereby rejecting a true null hypothesis

It is the probability of rejecting a nulll hypothesis with a probability of test suffering  an error of  type I type

Hence, option C is correct

What are the frist 3 stages of the cell cycle called?

Answers

The first three stages of the cell cycle are collectively called the "Interphase". Interphase comprises 3 stages specifically G1, S1 and G2. G1 is called the First Gap Phase, followed by S phase for synthesis and then G2 for the second gap phase. I hope this helps you. 
Interphase proceeds in three stages, G1, S, and G2, preceded by the previous cycle of mitosis and cytokinesis. The cell's nuclear chromosomes are duplicated during S phase.

Research involves quantitative and qualitative research. Qualitative is a type of research that involves observation and collection of data but include a control. Qualitative research involves, case studies, phenomenology, archival studies, naturalistic observation and the related. These are based on experiences, observations and subjective perceptions of the researcher and the subject being studied.
