cells with 23 chromosomes each.
B. Meiosis creates body cells with 46 chromosomes each, and Mitosis creates sex
cells with 23 chromosomes each.
C. Mitosis - crossing over occurs, and matching pairs of chromosomes (homologous
pairs) separate
D. Meiosis, two new cells are produced, and they have the total number of
chromosomes (46).
Answer:
mitosis: 1.is cell division
2. daughter cells are identical to the mother cell in terms of the number of chromosomes
3. passes through several phases
meiosis
1. The zygote is the most concrete example of division
2. daughter cells are not the same as the mother cell in terms of the number of chromosomes

Rabbits normally eat some grass as a food source. In a habitat, a new species of grass is introduced that out-competes most of the original species of grass. The new species of grass contains a chemical that is usually toxic and fatal to most rabbits. Assuming that all rabbits in this habitat will eat some of the new species of grass, how will the presence of the new grass most likely decrease the diversity of the rabbit population in this habitat?
Answer:
Well The Diversity will decrease.
Explanation:
If the Grass Is Toxic to the Rabbit than the rabbits will either die from eating the grass, or they will stop eating it and need to find a new food source. this will lead to the to the rabbits that are resistant to the toxic grass being able to reproduce more and therefor becoming more abundant.

Since the elephant’s diet consists of play material only, where would the elephant get the missing element needed to make collagen (or any protein)?
Answer:
The elephant is a herbivores animal and feeds on plant material that consist of cellulose. Collagen is a type of protein that is absent in plant material and only found in skin, tendons, bones and muscles. The elephant also requires collagen to replace or repair their skin cell in every 2 weeks.
As elephants are unable to consume meat that contains collagen, they get collagen or protein from the plant material only with the help of bacteria or enzymes present in its guts. The bacteria having enzymes that helps in the breakdown of cellulose and access the proteins, fat or sugar present in the plant cell.
Elephants get collagen and other proteins from the vegetables they consume.
We can arrive at this answer because:
Collagen is essential for the maintenance of the skin.However, collagen is found in large amounts in meat.Few vegetables have collagen and elephants only feed on vegetables.However, the demand for collagen in the elephants' body is met by feeding on vegetables rich in cellulose and vitamin C.When cellulose is digested and vitamin C is used in the body, collagen production is stimulated.

at 5 cm deep and another seed sitting on the top of the soil. Explain why. (2-3 complete sentences)
WILL GIVE BRAINLIEST TO BEST ONE
Answer:
The seed which is buried deep in the soil won't germinate
because
it won't get sufficient oxygen / airit won't get sufficient sunlight and etc...Answer:
Seed that had been planted 10cm deep won't get enough sunlight and adding water to make it grow just makes the condition even worse.
Seed that had been planted 5cm deep might not get sufficient sunlight because the rays of the sun cannot pass through the soil.
Seed that is on the top of the soil might get carried away by the wind, or dried due to extreme sunlight, or might get carried away by a predator.

Emotive language refers to language designed to target an emotion – positive, negative, sometimes deliberately neutral – and to make the audience respond on an emotional level to the idea or issue being presented.
Emotive language is an extremely important technique in creating audience engagement with a text. Also called 'loaded language', emotive language occurs when authors choose words extremely carefully to evoke specific emotional responses in a reader.

Which statement correctly describes how an organelle contributes to the ability of the cell to perform life functions?
The lysosomes digest food and break down cell parts when they die and the cell membrane prevents all harmful substances from entering the cell. So, the correct options are C and D.
What is Cell?Cell is defined as the smallest unit that can live on its own and that makes up all living organisms and body tissues where the cell has three main parts: cell membrane, nucleus, and cytoplasm. The cell membrane surrounds the cell and controls the movement of substances into and out of the cell.
A single cell is itself an organism. For example, yeast or bacteria. Other cells acquire specialized functions soon after they mature which acquire unique functions when they mature. They cooperate with other cells and become the building blocks of multicellular organisms such as humans and animals.
Therefore, the correct options are C and D.

found in the leftmost column of the periodic table, known as Group 1. Use the interactive
periodic table to explore the properties of the following alkali metals: lithium (Li), sodium
(No), potassium (K), rubidium (Rb), and cesium (Cs). The animations demonstrate a chemical
property common to alkali metals: they react with water. How does the reactivity vary
among this group of elements? Why might patterns like this be useful to scientists?
Answer: This might be helpful because t is a good basis for organizing elements because each element has a unique number of protons and atomic mass is an indirect way of organizing elements by number of protons.

х
O codominance because he fruit color of the offspring is

O codominance because both parents' colors are
expressed in the offspring
O incomplete dominance because both parents' colors
are both visible in the offspring
O incomplete dominance because the fruit color of the
offspring is an intermediate form of the parents' fruit
color
Answer:
incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color
Sry if I'm wrong, have a nice day.
The given image shows incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color. The correct option is D.
What is incomplete dominance?When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance.
This sort of gene interaction frequently produces an intermediate or distinct phenotype. Additionally called partial dominance.
Two other types of genetic inheritance are codominance and incomplete dominance. It basically means that no allele can prevent or stifle the production of the other allele through codominance.
Incomplete dominance, on the other hand, occurs when a dominant gene does not entirely block the effects of a recessive allele.
Fruit produced by two parents and fruit produced by one of their children are shown in the photo.
Because the fruit color of the offspring is an intermediate version of the fruit color of the parents, it is incomplete dominance.
Thus, the correct option is D.

How are the phases of Venus different than the phase of our moon?
Answer:
Venus is an inferior planet. Because Venus is so close to the Earth and lies nearer to the Sun, it shows phases, similar to the way the Moon does. It also is closer to us near inferior conjunction (bigger) than at superior conjunction (smaller), and so its angular size changes as the distance between us varies.

A. an atom
B. a nucleus
C. a proton
O D. an electron
Answer:
The smallest particle is the electron (option D).
Explanation:
The electron is a subatomic particle, which is part of an atom and has a negative electrical charge.
Electron is a small particle, if compared to protons -electrically positive particles- whose size is about 1800 times bigger. In fact, the electron is the smallest particle inside the atom.
According to this, the other options, atom, nucleus and proton are structures larger than an electron.
