compare blood cells to plant cells, include details about color, general shape, and size.
Blood cells are red, squishy, rounded, and have an indentation in them in the middle. Plant cells are green and firm and have a more square, boxy shape. Plant cells are larger than blood cells.
Plant cell is different in size, colour and shape from blood cell.
Plant cell has cuboid shape whereas blood cell has biconcave discoid shape. The colour of blood cell is red if it has oxygen or brown if it is no oxygen whereas plant cell has green colour. Plant cells have cell walls, ribosomes, endoplasmic reticulum, DNA and lysosomes but blood cells have no ribosomes, no endoplasmic reticulum, no DNA molecule and no lysosomes. The size of blood cell is 6.2–8.2 µm whereas the size of plant cell has 10 to 100 micrometers so we can conclude that there are a lot of differences between plant and blood cells.https://brainly.com/question/21283369

Which part of the dna experiences
the mutations
Answer:
Nucleotide
Explanation:
Which of the following is used to screen for carcinogenic potential of various compounds?
transformation testing
replica plating
Ames test
ELISA test
Answer:
Ames test
Explanation:
This is because Ames test is a test that uses bacteria strain i.e Salmonella typhimurium to check or assess of a chemical has carcinogenic effect of it. It uses mutagenicity of bacteria. It is a biological assay that test whether an a chemical can cause mutations in the dna of the test organisms. When mutagens are added and also liver enzymes, there would be a reverse mutation and this will lead to their growth

In which parent could chromosomal rearrangement have made an X chromosome with 2 fur color alleles?
Answer:
Mother
Explanation:
(see image below)
According to the given situation, the mutation needs 2 X chromosomes and only the mother has 2 X chromosomes whereas a father has X and Y chromosomes.
What are the 23 chromosome pairs?Humans have 23 pairs of chromosomes, 22 pairs of numbered chromosomes, and 1 X and Y chromosome (father) and mother have (XX) chromosomes.
Each parent donates one chromosome to each pair so that offspring get half of their chromosomes from their mother and a half from their father.
Thus, the mother is an answer.

Which of the following is a correct statement about evolution?
A. Evolution is a change in the morphological characteristics of a species
B. Evolution is a change in size characteristics of a species
C. Evolution is a change of allele frequency from one generation to the next
D. Evolution is the change in the physiological characteristics of a species
E. All answers are correct
Answer:
C. Evolution is a change of allele frequency from one generation to the next
Explanation:
Evolution is the gradual change that occurs to living organisms over successive generations. According to Charles Darwin, these changes aid in the adaptation of the species of an organism to their environment. In other words, it makes them better fit.
Charles Darwin further stated that since evolution is dependent on natural selection i.e selection of the best fit by environmental factors, the changes that the organism undergo are genetic. Hence, evolution is a change of allele frequency from one generation to the next.
4. Living things are sometimes called "carbon-based life forms." Do you think this is a good way to describe life? Explain your answer., help me asap
Answer:
Explanation:
Yes, for a couple of reasons.
1. Carbon connects easily with other carbons.
2. Carbon forms chemical that can change and connect with other carbons even in biology or especially in Biology. If you take a brown seen and plant it where it can get water and soil nutrients, to will come up as a green plant. Think about the chemistry that goes into that. Not only that, but there are mechanisms that tell the upper part of the plant that the roots can't supply any more growth. Isn't that something? All made from Carbon.
3. The human body is a mass of Carbon based chemicals and all cells there can have different functions. Amazing isn't it? I'm a fan of the diversity of our planet and its growth.
Why would you consider amphibians to have great biodiversity?
Amphibians are vertebrates in the class Amphibia that includes frogs, toads, salamanders, newts, and caecilians (wormlike amphibians). Amphibian species are considered important biological indicators of the health of an ecosystem because they live in both aquatic and terrestrial environments.

Eric drops a 3.70 kg water balloon that falls a distance of 20.38 m off the top of a building. What is the velocity at the bottom?
Answer:
The velocity of the balloon at the bottom is 19.99 m/s.
Explanation:
Given;
mass of water balloon, m = 3.7 kg
height of fall, h = 20.38 m
The velocity of the balloon at the bottom is calculated from the law of conservation of energy;
[tex]K.E_{bottom} = P.E _{top}[/tex]
[tex]\frac{1}{2}mv^2 = mgh \\\\ v^2 = 2gh\\\\v= \sqrt{2gh} \\\\v = \sqrt{2\times 9.8 \times 20.38} \\\\v = 19.99 \ m/s[/tex]
Therefore, the velocity of the balloon at the bottom is 19.99 m/s.

what factors determine how much the motion of the air molecules will change
The factors that determine how much the motion of the air molecules will change are:
.The rate of diffusion which is affected by the concentration gradient, .membrane permeability.temperature.pressureThe movement of substances from a region of higher concentration to a region of lower concentration is called diffusion of particles. This phenomenon is very important in cellular transport in plants.
The rate of diffusion is affected by 4 factors namely:.concentration gradient: Diffusion takes place when there is a difference between the concentrations of a substance across a barrier. Diffusion stops when the concentrations of the substance on either side of the barrier become equal.
.membrane permeability: Diffusion rate increases as membrane permeability increases.
.temperature and pressure is paramount in the diffusion of gases as gases diffuse from a region of higher partial pressure to a region of lower partial pressure. Same as in terms of temperature.

Describe how plants and animals each contribute to the survival of the other. (This type of cooperative relationship is called interdependence.)
Answer:
Plants produce oxygen which is used by animals in the process of cellular respiration, while animals produce carbon dioxide which is required for plants to make the photosynthesis process
Explanation:
In biology, interdependence can be defined as a mutual dependence relationship among two (or more) taxonomic groups. Animals and plants are cooperatively interdependent because they mutually need each other for different essential aspects of life such as food, respiration, refuge, protection, propagation, etc. For example, plants produce oxygen which is used by animals for cellular respiration (obtaining energy from this process), since most animals are aerobic organisms. Similarly, animals release carbon dioxide (CO2) when they breathe out, and CO2 is used by plants to perform photosynthesis (i.e., to produce energy and carbohydrates from this process).

Since its inception, the theory of evolution has been the subject of frequent debate. Those who oppose evolutionary theory often point to gaps in the
fossil record in an attempt to discredit the theory. Which statement would be the best counterargument as to why the fossil record can be relied upon to
support evolution?
The fossil record provides evidence that extinct species only fossilized during certain geologic eras.
The fossil record provides evidence that extinct species are genetically identical to current species.
The fossil record provides evidence of many different types of organisms, since most species fossilize well.
The fossil record provides evidence of many transitional organisms that show relationships between species
Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)

Answer:
Insects that have complete metamorphosis have four life stagesInsects going through their immature stage are called larvaeInsects then enter an inactive state called pupa, or chrysalis. Whilst inside the pupa, the insect will excrete digestive juices, to destroy much of the larva’s body, leaving a few cells intact.In the final stage of the metamorphosis, the insect finally breaks through the pupa emerging as a full adultExplanation:
