Answer:
Meiosis
Explanation:
While mitosis makes two identical cells with the same numbers of chromosomes, meiosis makes four unique daughter cells, from which every cell has half of the number of the chromosomes as the parent cell.
Meiosis is the specified form of cell division, making the reproductive cells, like sperm and egg cells, for example.

A scientist finds that a sample of matter contains three types of atoms. The sample can be any of the following, except:
A. compound
B. molecule
C. element
D. mixture
Answer:
D. mixture
Explanation:
because the mixture is not part of an atom
As per the given scenario, the sample can be any of the following, except element. The correct option is C.
What is an element?A substance that is unable to broken down chemically into smaller molecules.
An element is made up of atoms with the same atomic number, which means that each atom possesses the same count of protons in its nucleus as the other atoms in the element.
A chemical compound is a chemical substance made up of many identical molecules made up of atoms from multiple elements that are held together by chemical bonds.
A molecule made up of only one element's atoms is thus not a compound.
A scientist discovers three types of atoms in a sample of matter. Except for elements, the sample can be any of the compound, molecule or mixture.
Thus, the correct option is C.

Explanation:
Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen. The correct option is C.
What is cellular respiration?Cellular respiration is a sequence of chemical processes that decompose glucose to start producing ATP, which can then be used as energy to power a wide range of processes throughout the body.
Cellular respiration consists of three major steps namely glycolysis, the citric acid cycle, and oxidative phosphorylation.
The use of photoautotrophic procedures to obtain the glucose required for cellular respiration is an illustration of cellular respiration in plants.
This means that plants can use light energy from the sun to produce glucose and oxygen.
On the other hand, the process of photosynthesis utilizes carbon dioxide and release oxygen as a byproduct.
Thus, the correct option is C.

Sickle cell anemia is a genetic condition that occurs because of a single point mutation in the DNA gene for hemoglobin. How is this mutation expressed in humans?
Answer:
Hello. Let me explain.
Explanation:
This type of anemia first of all before the Erytrocyte loses its nucleus ،at chromosome number 11 this mutation happens and valine (s type of amino acid)is replaced with glutamic acid.
Then this abnormal hemoglobins are produced in ribosomes (after transcription and translation).
This hemoglobins make a long strand which makes the RBC have a sickle shape.
This abnormal cells are very fragile.
The normal RBC is alive for about 120 days but this cells are slive for just 15 days.
This sickle shaped cells can also close blood vessels.
Macrophages destroy them so the anemia accurs.
Explain Why is there a net gain of onlý two ATP
molecules in the glycolysis of one six-carbon glucose?
Answer:
While 4 molecules of ATP are produced in total, 2 were used to convert glucose to the reactive fructose-1,6-bisphosphate
Thus, 4 ATP- 2ATP= 2ATP
Explanation:
In the cytoplasm, cellular respiration starts, where glucose is broken down for energy production. in the presence of oxygen, energy is produced through aerobic respiration, while in an oxygen-deprived environment, anaerobic respiration can be carried out.
Glucose is a relatively stable molecule, thus in order for the pyruvate-producing reaction to occur, the molecule undergoes phosphorylation through the addition of high energy phosphate groups to drive the reaction forward.
Pyruvate is generated through glycolysis in the cytoplasm-it is oxidized to form acetyl CoA in aeroboc respration also used in fermentation (anaerobic respiration) as an electron acceptor.

The duck-billed platypus’s name come from its snout, which looks a lot like a duck’s bill. It has another birdlike characteristic; it lays eggs, which is quite unusual for mammals. In fact, there are only five known mammals that lay eggs. The other four are four species of echidna, also called the spiny anteater. The duck-billed platypus is classified as a mammal because it has body hair, it’s warm-blooded, and the females produce milk.

In the box provided explain why living organisms
contain more hydrogen atoms than any other
atoms, yet 65% of a typical organism's mass is
oxygen
І
Answer:
Explanation:
Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.
Answer:
The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

What does the energy from sunlight actually do to the plant cell? *
It heats up the plant cell
It excites electrons
It is unknown
It transforms to kinetic energy
Answer:
It excites electrons
Explanation:
Energy from sunlight excites electrons in plant cells and drives the chemical reaction needed to produce food in plants.
This reaction is called photosynthesis. During photosynthesis, green plants manufacture their food using sunlight in the presence of carbon dioxide and water. The product of the reaction is glucose and oxygen gas. The role of the sunlight is to excite electrons which facilitates the process.
Sperm cells of a specific species of mice have 16 chromosomes. What is the expected number of chromosomes in an adult mouse of this species?
Answer:
32 chromosomes (16 pair)
Explanation:
Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.
That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes
