"I don't get it. Why do I need to learn about meiosis to understand about variation in a species?" moaned Trina. How would you explain to her what the relationship is between the two?
Answer:
The cell division that halved the no. of chromosomes is the meiosis. The meiosis takes place during formation of gametes (eggs & sperms) in higher organisms. eggs & sperms posses only one chromosomes of each pair of chromosomal set. (2n➡️n).
When these gametes fuse to form the zygite, the chromosomes become n+n➡️2n again.
Cells created by meiosis can be
represented by which of the following?
A.2B
B.B
C.2N
D.N
Answer:
D. N
Explanation:
Meiosis is a kind of cell division which produces daughter cells that are genetically different from the parent cell and have a reduced number of chromosomes (by half).
Meiosis occurs only in reproductive cells to produce gametes. If a diploid (2n) cell undergoes meiosis, a haploid (n) daughter cell will result. This means that the chromosome number has been reduced by half in order to maintain the chromosomal number of the next generation.

Explain what happens to an animal cell when it removed from an organism and placed into distilled water
Answer:
I think it has to do with osmosis
Explanation:
Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.
When a cell is placed into distilled water, hypertonic solution takes place.
A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.

There are 42 gallons in one barrel of oil. How many barrels of oil are equivalent to 2,572.5 gallons of oil?
Answer:
The 62.25 barrels of oil are equivalent to 2562.5 gallons of oil
Explanation:
Given that :-
There are 42 gallons in one barrel of oil.
To find :-
How many barrels of oil are equivalent to 2,572.5 gallons of oil?
Solution :-
If 42 gallons oils in one barrel of oil
so, barrels of oil are equivalent to 2562.5 gallons of oil = 257.5/ no. of gallons in one barrel
= 257.5 / 42
barrels of oil equivalent to 2562.5 gallons of oil = 61.25Hence, 62.25 barrels of oil are equivalent to 2562.5 gallons of oil

A cactus is adapted for life with limited water. The green
part of this cactus is its stem. Its stems are fleshy and
have a thick waxy coating.
What are two ways the structure of this cactus's stem helps the plant survive?
A. It takes in minerals from the soil.
B. It prevents water loss.
C. It carries out photosynthesis.
D. It holds the plant in the ground.
Answer:
i think its B hope it helps
Explanation:
Adaptations are the alteration that allows the survival of the fittest. The adapted structure of the cacti allows it to take the minerals from the soil and prevents water loss. Thus, options A and B are correct.
What are adaptations of cactus?Adaptation is seen as the modified physical and chemical characteristics that allow the organism to survive in stressful conditions. A cactus has adapted spines, roots, waxy skin, and deep-layered stomata.
These adaptation has allowed the cactus to survive the harsh conditions of dessert. The wide fibrous roots allow it to draw nutrients and minerals from the soil.
The thick, expandable stem with deep-layered stomata prevents the loss of water from the surface in high-temperature conditions and keeps the plant hydrated.
Therefore, options A and B. the adapted attributes of cacti prevent water loss.

The outcome of protein synthesis is ______.
A. A glucose molecule
B. An mRNA molecule
C. A protein
Answer:
C. A protein
Explanation:
The outcome of protein synthesis is a protein.
The process of protein synthesis is crucial to cellular function. Protein synthesis is the procedure used by cells to generate proteins. Thus, option C is correct.
What is the role of protein synthesis in the cell?Protein synthesis, sometimes referred to as protein biosynthesis, is an essential biological process that occurs inside of cells to replace lost proteins (due to export or degradation) with new proteins.
Proteins have a wide range of vital biological functions, including those as enzymes, hormones, and structural proteins.
Cells are made of proteins, and the word “synthesis” simply means “to make.” Thus, the process of producing proteins is known as protein synthesis.
Creating a polypeptide, or protein consisting of a chain of amino acids, is the sole goal of protein synthesis. Keratin, a protein, is produced in the cells of the hair follicle.
Therefore, The outcome of protein synthesis is a protein.

Explain how the formation of a submergent coastline differs from the formation of an emergent
coastline.
Answer:
One occurs when sea level rises whereas the other happens when the sea level drops.
Explanation:
The main difference between Submergent coastlines and emergent coastlines because Submergent coastlines formed when sea level rises or in other words, the land sinks down. Examples of submergent coastlines are estuaries, barrier bars, and barrier island systems while on the other hand, emergent coastlines occurs when sea level drops or the land rises. Hudson Bay and Eastern Coastal Plains are the examples of emergent coastlines.

Cellular respiration definition ?
Answer:
cellular Respiration is that cells use oxygen in mitochondria to make ATP and GTP for cells
Answer:
Cellular respiration occurs when cells utilize oxygen in their mitochondria to produce ATP and GTP.
Cellular respiration is a series of reactions that occur under aerobic conditions and result in the production of large amounts of ATP.
Explanation:
Glucose, the basic building block for starch and many sugars are one of the main sources of energy in our diet. Its oxidation can be divided into three phases in the respiration of the cells: glycolysis, the cancer cycle, and the electron transport system.
Aerobic breathing uses eukaryotes to generate energy, including all multicellular organisms and some single-cell organisms. Aerobic breathing uses oxygen – a powerful, in-kind electron acceptor.
Aerobic breathing is an extraordinarily effective process that enables eukaryotes to have complicated life and active lifestyles. It also means however that they need a continuous supply of oxygen or that they cannot get the energy to stay alive.
Other forms of respiration, which are slightly less efficient, can be used by procharian organizations such as bacteria and archaebacteria. They can therefore live in environments in which eukaryotic organisms cannot live because they do not need oxygen.
