What does the notation TT mean to geneticists

Answer;

Three ways that scientist can use to avoid bias are;

- Sampling method

- Using blind study

- Repetition

Explanation;

Sampling method involves the studying of a small quantity of a particular aspect in order to form an opinion about the whole population. To avoid bias its important to obtain samples that are appropriate and that would cover the entire participants studied.

-Repetition involves repeating a particular experiment several times in order to ensure that one gets the same results that is ensure accuracy of the results.

-Blind study involves an experiment in which the control and the variable groups are conceal from the participants until after the end of the experiment. It is an important factor to avoid bias in scientific research.

Final answer:

Scientists can minimize bias in scientific investigations through randomization, blind studies, and double-blind studies.

Explanation:

There are three ways that scientists can minimize bias in scientific investigations:

1. Randomization: Scientists can assign participants or samples randomly to different groups or conditions to ensure that each group is similar and reduce bias.
2. Blind studies: Scientists can conduct blind studies where participants or researchers are unaware of the group assignments or the purpose of the study to prevent biased behavior or expectations.
3. Double-blind studies: Scientists can also conduct double-blind studies where both the participants and the researchers are unaware of the group assignments to further avoid bias.

Explanation:

Consumers are usually at thetop of the food chain and eat othere animals. Hope this helps

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.

They would have concluded that the protein coat also entered the bacterial cell and could not deduce that protein is the genetic material.

Explanation:

In their experiment, Hershey and chase found that all the DNA coated with 32 p were missing from the solution as bacteriophage after adsorption on bacterial cell their DNA was transferred to the bacterial cell. The presence of 32 S in the solution shows that the protein coat does not enter the cell during infection.

This way they concluded that DNA is the genetic material and not the protein.

Since phage infecting bacteria inserted their DNA into it and got replicated increasing their number. Also, protein is not involved in their growing numbers.

Answer (True/False):

FALSE

Explanation:

Atomic number defines the number of electrons and protons in an atom. where as synthesizes means to produce something chemically. Keeping both the statements in view, it is not easier to synthesize new elements with a large number of electrons and protons. Though this process can be done for the small atomic numbers.
