"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.

in your own words, write the definition for Phagocytosis.
how is Phagocytosis related to endocytosis?
Answer:
Process by which phagocytes ( a type of cell from the immune system) engulf other particles
Explanation:
Endocystosis is the process of bringing particles/substances into a cell (endo-in). Therefore phagocytosis is a form of endocytosis.

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.
Osmosis, where sea water and fresh water on different sides of a permeable membrane will end up "brackish" with equal content over time is an example of what?
A) Passive transport
B) Active transport
C) Transitive chemistry
D) A lipid bilayer
I know it’s probably between A and B, but I have a hard time telling the difference.
Answer:
A) Passive transport
Explanation:
The answer for the question is A

Amoebas make exact copies of themselves. Therefore, they reproduce
A. asexually buy the process of MEIOSIS
B. sexually by the process of MITOSIS
C. sexually by the process of MEIOSIS
D. asexually by the process of MITOSIS
Answer:
D.
Explanation:
You can rule out B and C because offspring produced sexually are not identical to their parents. The amoebas reproduce by binary fission, which is a form of asexual mitosis.
Answer:
D. asexually by the process of MITOSIS
Explanation:
Mitosis is a form of asexual reproduction in simple living organisms. The outcome of each cell cycle is two identical cells. Mitotic checkpoints happen at certain stages of mitosis to ensure that each cell receives the same amount of DNA.

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.

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.

Read the following selection and answer the question. On a September day in 1999, people began to notice that Lake Jackson in the Panhandle region of northern Florida was shrinking. Within a few days, it was almost gone. A sinkhole had opened beneath the lake and drained it, along with all of its inhabitants including fish and alligators. As aquifers lose water, rock and soil layers can become weaker and less capable of supporting overlying layers of earth and any human structures built upon them. In such cases, the land surface above may subside, or sink. Sometimes subsidence can occur locally and suddenly in the form of sinkholes, which are areas where the ground gives way with little warning. Once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. Recharging a depleted aquifer may therefore become more difficult. Sinkholes occur when?
Answer:
Sinkholes occur when water from the groundwater has been removed in excess.
Explanation:
Sinkholes are empty spaces in the ground that occur due to the landslide of large volumes of land, creating craters of different sizes. This landslide takes with it everything that is on top of it, such as houses, animals, streets and even entire buildings. While these holes can occur due to engineering flaws, the most common reason is the excessive use of groundwater, which creates an empty space in the interior of the soil and causes the earth to sag.

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.
