what is polygenetics ?​

Answers

Answer 1

Explanation:

is a member of a group of non epics tactic genes that interact additively to influence a phenotypic trait

Answer 2

Answer (three definitions, where two are biology and one is geology):

1) (biology) Of or pertaining to polygenesis; polyphyletic.

2) relating to or determined by polygenes.

If you don’t know what a polygene is: A polygene or multiple gene inheritance is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait.

3) (geology) One which is composite, or consists of two or more monogenetic ranges, each having had its own history of development.

Hope this helps! :)

Explanation:

Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.

identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?​

Answers

Answer:

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

Radiation does not have effect on strength of the mice

Explanation:

In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.

The control group is the group that does not receive treatment which is used to compare the effect of the treatment.

The control variable is another variable that must be held constant when performing the experiment.

Here the

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.

n the northern United States where snow and ice create dangerous road conditions in the winter, the Department of Public Transportation often salt roads, which encourages melting. How could salting the roads have and impact on the plant life that live on the edge of the road?

Plant cells will lose water due to osmosis.


Plant cells will gain water due to osmosis.


Plant cells will use the salt to grow taller.


There would be no impact.

Answers

Answer:

Plant cells will lose water due to osmosis

Explanation:

Osmosis uses a concentration gradient. Water travels from areas of high concentration to low concentration. The salted road has low water concentration while the plants near the edge have a higher water concentration. The water will leave the plants and go to the salted road. Using common sense, if you sprinkle salt on a snail, it dehydrates and dies. Same thing happens here. The salt sucks the water out.

What is the classification of virus​

Answers

Answer:

Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.

Many viruses attach to  host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.

The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.

Explanation:

not sure if this is what you are looking for

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.

What is Virus?

A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.

Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.

Class 1: Double-stranded DNA viruses.

This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.

Class 2: Single-stranded DNA viruses.

Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.

Class 3: Double-stranded RNA viruses.

Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.

Class 4: Single-stranded RNA viruses (positive sense).

Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.

Class 5: Single-stranded RNA viruses (negative sense).

Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.

Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.

Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.

Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.

Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.

Therefore, it is well described above.
