describe two ways to transfer electric charge
.Answer: conduction or polarization
Answer:
conduction, friction
Explanation:
Friciton: When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.
Conduction: During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod.

- Have cells that are simple with no nucleus
- Found in extreme environments like volcanic vents
- Am unicellular
- My cell wall does not contain peptidoglycan
a- Plantae
b- Eubacteria
c- Fungi
d- Archaebacteria
Answer:
The correct answer is - d- Archaebacteria.
Explanation:
Archaebacteria is the organism of the prokaryotic cell organism and lacks double membrane-bound organelles and nucleus and has the chromosomes present in the nucleoid.
These cells are different than eubacteria as they lack peptidoglycan or murein in their cell walls like eubacteria. This group of organisms is found in extreme conditions like halophile, drought, or volcanic heats. Archaea is the third domain other than eukarya and bacteria.

according to the dichotomous key organism 3 is a
A) leech
B) bristle worm
C) water scorpion
D) dragonfly nymph
Answer
The correct answer is A) leech
Explanation:
According to the dichotomous key organism 3 is a leech. Therefore, option (A) is correct.
What is a dichotomous key?A dichotomous key is a tool used by biologists to identify organisms based on their characteristics. It consists of a series of questions with two possible answers for each question. By following the path of the key, the user can narrow down the possible identities of the organism until a final identification is reached.
Dichotomous keys are often used to identify species in fieldwork and can be based on physical characteristics such as color, size, and shape, or other traits such as behavior, habitat, and geographic range. These keys provide an efficient way to identify organisms and are widely used in fields such as ecology, botany, and zoology. However, the accuracy of a dichotomous key depends on the quality and specificity of the questions used and the expertise of the user in interpreting the results.

solid are tightly packed- the particles are close together.
Hope this helps:)
Answer:
Solid: Molecules are tightly together to hold the shape.
Liquid: Molecules float around to fill the space of the container that they are in.
Gas: Molecules have no definite shape and move freely.
describe the product of mitosis
The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes. ... A chromatid, then, is a single chromosomal DNA molecule. In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.

Hello. Your question is incomplete. The complete question asks for the correct answer to be found based on Catalase is an essential enzyme in living beings since all cells need it.
Answer:
B. Cells only function within a specific temperature range because enzymes only function within a specific temperature range.
Explanation:
Catalase needs to be present in all cells of the living organism because it is responsible for the decomposition of hydrogen peroxide that cannot stay inside cells for long periods of time. Following this type of reasoning, we can say that it is necessary to maintain a constant temperature for the enzymes of an organism to function well because all enzymes have a specific temperature range, even catalase.
The specific temperature range determines that the enzymes will only work within that range. Therefore, an environment where the temperature is below or above that specific range, can prevent the enzyme from functioning and even cause irreversible damage to the enzyme.

If the blockage is removed from the blood vessel, what will happen to blood flow after removal?
Answer:
the blood would stop pumping, because the blockage allows the blood to move one way, but when there is not blockage, the blood would enter from both ways making it impossible to regulate
Which is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in the environment, causing individuals to change 3. There must be some genetic differences among the individuals of a species 4. all of the above
Answer:
It's 3!
Explanation:
There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.
And it can't be 4 if 1 and 2 are wrong!
Hope this helped!

Whích statement is best supported by the diagram?
А.
Species T and Species U are related to species X
B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.

A population of mosquitoes is exposed to the pesticide DDT for several generations. At the end of that time, most individuals in the population are resistant to DDT. The most likely reason is that:
A. random mutations in each generation made mosquitoes resistant to DDT.
B. some individuals in the original population had the mutations that led to resistance.
C. DDT caused the mutations that led to resistance.
D. somatic mutations in the original population were passed on to subsequent generations.
E. by chance, new mutations that led to DDT resistance arose after DDT was used.
Answer:
B
Explanation:
A population of mosquitoes is exposed to the pesticide DDT for several generations. At the end of that time, most individuals in the population are resistant to DDT and the most likely reason is that some individuals in the original population had the mutations that led to resistance. Option B is correct.
What is mutation ?Mutation is the change in which there is slight change in the genome sequence of a DNA or RNA along with the gene. The mutation lead to various types to adaptations along with the diseases.
Resistance is the condition when the species on the multiple exposures develop certain kind of adaptations to it and these traits are sometime inherited sometimes not inherited.
Mutations are friendly as well where sometimes a disease causing mutation can be altered with the further mutation in it.
Therefore on the multiple exposure it led to condition of resistance in the species.
