Answers

Scientists make a person’s genes fluoresces by having to name a variety of chromosomes on what color would variant. What would it do is that it can find it’s whole color scheme in order to locate the chromosomes which is basically a spectral karyotype.
By using multiple probes labeled with a mixture of different fluorescent dyes, scientists are able to label each chromosome in its own unique color.

A. the surroundings
B. the components
C. the flow
D. the boundary

Answers

Answer:

(C) The flow

Explanation:

The processes that transform inputs into outputs are the flow part of the system that is presented in Option C, as the flow determines the efficiency and effectiveness of the system.

What is the significance of the flow in the system?

The flow in the system has many implications, such as how it transforms inputs into outputs and it is a crucial part of a system, and it explains how the inputs are transformed and the output for the respective inputs. The flow affects the system's overall performance and helps manage the outcomes of the system by achieving its desired roles or functions.

Hence, the processes that transform inputs into outputs are the flow part of the system that is presented in Option C, as the flow determines the efficiency and effectiveness of the system.

Which type of cell has free-flowing DNA? O Fungi O Prokaryotic O Eukaryotic O Protist​

Answers

Answer: Prokaryotic cells have free flowing DNA. This DNA is in a circular shape and flows freely in the cytoplasm

Answer:Prokaryotic cells

Explanation:

Prokaryotic cells as well as bacteria have a free-floating chromosome that is normally circular and is not enclosed in a nuclear membrane instead The DNA simply lives in a region of the cell called a nucleoid.Prokaryotic cells only have a small range of organelles, normally  only a plasma membrane and ribosomes

What is a Prokaryotic cell?

Prokaryotic cells comprise bacteria and archaea. They Normally  have a diameter of 0.1–5 μm, and their DNA is not contained within a nucleus. alternatively , their DNA is circular and can be located  in a region called the nucleoid, which floats in the cytoplasm

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.

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
