what is theory of to observe the neucles in cheek cells

Answers

Answer: The theory of cheek cells is used for the identification of cheek cells.

Explanation:

The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.

17 Some Birds with shorter beaks enter into a population of birds with much
longer beaks, resulting in the hatching of birds with in-between sized beaks.
Which No evolutionary mechanism are most likely responsible for this
scenario

A mutation and genetic drift

B natural selection and artificial selection

C gene flow and recombination of genes

D artificial selection and crossing over during melosis

Answers

I think it’s c because the birds have different beak sizes it could be mutation or different genes

The evolutionary mechanism that are most likely responsible for this scenario is:

C gene flow and recombination of genes

According to the given question, some birds are said to have shorter beaks and when they mate with birds that have longer beaks, they produce offspring that have in-between size beaks.

The evolutionary mechanism that is in charge of this phenomenon is simply gene flow and recombination of genes. This is because there is a combination of genes from the parents and given to the offspring.

The shorter beaks and the longer beaks of the parents combined and the offspring got in-between beaks.

Therefore, the correct answer is option C

What materials do motor neurons need to survive and how do they get those materials?

Answers

Answer:

Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

What are the sex chromosomes? Explain how it is shown in male and female; and karyotyping

Answers

Answer:

Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.

Explanation:

Sex chromosomes are chromosomes which are responsible for sex determination. These are the X and Y chromosomes. Females have two X chromosomes and males have one X and one Y chromosome in their sex cells/gametes. Karyotyping is the visualization of chromosomes after blocking the cells in mitosis and staining; this allows us to identify the size, shape, and number of chromosomes present in cells, which is significant because extra, missing, or abnormal chromosomes can cause developmental problems or issues with body functions.
