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:

Why are there two sets of phases during meiosis, but only one during mitosis? Think about what is different about meiosis and mitosis
Answer:
Mitosis is the cell cycle for somatic cells which are diploid (2n).
Meiosis is the cell cycle for germ cells (gametes) where they are haploid (n) so that is why they have two sets of phases.

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.

Answer:
i wish i could help
Explanation:
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
we 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:

15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002

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.

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.
