Answer:
__________
Explanation:
In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent.
Answer:
Each parents gives of half of the genes acquired by the offspring. 46 chromosomes or 23 pairs.
Explanation:
". Each gamete contains half the number of chromosomes, or genetic material, of the organism. So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body. A basic human body cell contains 46 chromosomes, but the egg and sperm only contain half that number, or 23 chromosomes. Why? Well, when an egg and a sperm come together, which is a process called fertilization, they contribute 23 chromosomes each. Add 23 and 23 together, and you get one happy 46-chromosome-containing fertilized egg that can now develop into a new human.
Meiosis
Gametes are produced by a type of cell division known as meiosis. It's meiosis that reduces the number of chromosomes in the cell down to 23. It's also meiosis that makes gametes genetically different from one another. After the cell division takes place, each sperm and each egg has its own unique genetic makeup. In other words, meiosis can be thanked for giving Junior his cute mismatched ears. "

Describe the process of respiration which takes place in human beings whe
oxygen is not available and give an effect.
(T
Answer:
The process in which respiration takes place without oxygen is called as anaerobic respiration.
Aerobic respiration In anaerobic respiration the energy produced is very low as compared to aerobic respiration The organisms which use this type of respiration process are fungi, yeast In this process, (in yeast) glucose broke down into pyruvate and gives ethanol , carbon dioxide and energy In human muscle cells when there is a lack of oxygen this process occurs in which lactic acid and energy are produced.More to know -Pyruvate is three carbon -molecule.
The build up of lactic acid causes cramps in muscles.
When discussing Newton’s laws of motion, which terms do people most likely use when talking about Newton’s third law of motion?
A. “action” and “reaction”
B. “mass” and “inertia”
C. “inertia” and “force”
D. “force” and “acceleration”
Answer:
A. action and reaction
Explanation:
the third law is:-
Every Action has it's opposite and equal Reaction
Answer:
The correct answer is "action" and "reaction".
Explanation:
Newton's Third Law is: "for every action, there is an equal and opposite reaction". This means that every time something is pushed on, the other object pushes back. For example, when a swimmer pushes off the wall of a pool, the wall will push back on the swimmer, giving them the push they need to swim to the other side.

iwe have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012

All proteins found embedded in the cell membrane are transport proteins
Answer:
False!
Explanation:
False: All proteins embedded in the cell membrane are not transport proteins instead they are not just involved in transportation of molecules but also in other functions.
Cell membrane is the outer covering of most of the type of cells except in plants and bacteria where cell wall is the outermost layer.Cell membrane is made up of phospholipid bilayer. The proteins embedded in the cell membrane are not only the transport proteins but proteins that are responsible for cell to cell communication, responsible for maintaining shape of the cell, and those responsible for triggering chemical messengers all are present.Learn more about cell membrane:

what is the building block of nucleic acids
Answer:
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
I found this on google because I am not the best at explaining things but I hope this helps :)
The building blocks of nucleic acids are nucleotides, which consist of a sugar molecule, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
What are nucleotidesNucleotides are the building blocks of nucleic acids, such as DNA and RNA. They consist of a sugar, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
Nucleotides link together through phosphodiester bonds, forming the backbone of nucleic acid chains. The sequence of nitrogenous bases along the chain encodes genetic information. Adenine pairs with thymine or uracil in RNA, while guanine pairs with cytosine, creating complementary base pairs.
Nucleotides play a crucial role in storing and transmitting genetic instructions, serving as the foundation for DNA and RNA molecules.

During the process of photosynthesis, energy from the Sun is converted into A) chemical energy in the bonds of inorganic molecules B) chemical energy in the bonds of organic molecules like glucose C) enzymes used to produce inorganic molecules D) enzymes used to produce organic molecules
Answer:
b
Explanation:
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.
The correct option is:
Option B. chemical energy in the bonds of organic molecules like glucose
The process of photosynthesis involves:
Photosynthesis is carried out by plants. The leaves are the primary site for photosynthesis. The chloroplasts present in the plant cells are primarily involved in photosynthesis. Photosynthesis involves the capturing of light energy and storing it in the form of bonds of organic molecules like glucose and starch. The process involves carbon dioxide, water, sunlight, and green pigment chlorophyll to carry out photosynthesis. The products of the process are oxygen and sugar molecules holding the energy.
Thus, the correct answer is option B.
