Why is meiosis important in maintaining genetic diversity?
Question 6 options:
A Meiosis creates diversity by cutting each chromosome exactly in half.
B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.
D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.
Answer:
We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Explanation:
Brainliest please?
Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.
Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
Other options-
A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.
C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.
D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

Identify the control group for the rat experiments described in the Paralytic Shellfish Poisoning Scenario.
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the control group of an experiment is the group in which every other group of the experiment is firstly compared with. This is because control groups are usually not administered with any form of treatment. Thus, the control group of the experiment/scenario referred to in the question will be the group that did not receive any form of treatment and was probably given water or placebo.

Sheela wants to demonstrate the importance of photosynthesis to plants and the other living organisms that eat plants. She models the process of photosynthesis that is specifically involved in the production of sugars.
Which process in the light-independent reactions of photosynthesis is she modeling?
the production of oxygen
the production of glucose
the production of carbon dioxide
the production of water
Answer:
the production of glucose
Explanation:
sugar=glucose
Request:
(Brainliest plzzz)
In this process, the light-independent reactions of photosynthesis are she modelling, and the production of glucose. Thus, option "B" is correct.
What is the chemical reaction of photosynthesis?The chemical reaction of photosynthesis is given as follows;
6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)
Six molecules of gaseous carbon dioxide (CO₂) combine with six molecules of liquid water (H₂O) in the presence of energy from Sunlight to produce one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)
Thus, option "B" is correct.

What is biodiversity and why does it matter?
Answer:
The concept includes every species of bacteria, virus, plant, fungi, and animal, as well as the diversity of genetic material within each species. It also encompasses the diverse ecosystems the species make up and the ongoing evolutionary processes that keep them functioning and adapting.
Explanation:
Answer:
Biodiversity maintains the natural balance of ecosystems and every species has its niche. Species depend on each other in order to thrive from cockroaches to squirrel monkeys to pygmy elephants—and even the many of us who live in cities.

What does it mean to move UP the concentration gradient?
Answer:
Moving against the concentration gradient, or in simpler terms, moving from a low-concentration area to a high-concentration area.
Explanation:
This action uses energy, as according to entropy, the substance will move from a higher concentration to a lower concentration, and cells have to put extra energy to pump the molecules / substance up the concentration gradient.
It is mostly used to trigger chemical responses in cells, like in neuron synapses.

Describe the way convection works and how it might work within the earth? -geology question
Answer:
Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.

Which biomolecule provides the instructions to build enzymes?
A. Carbohydrates
B. Lipids
C. Nucleic acids
D. Proteins
Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.
What are enzymes?Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.
Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

Flagella proteins are found in the extracellular matrix of lung tissue. How do the cells of the lung detect these proteins? a. complement system b. toll-like receptors c. eosinophils d. NOD e. helper T-cells
Answer:
The correct answer is b.
Explanation:
TLRs are transmembrane type proteins 1, they are abundantly expressed in fibroblasts and epithelial cells, as well as in cells of the immune system, including macrophages, dendritic cells, B and T lymphocytes, and their expression is regulated by pathogens, cytokines, microenvironmental factors, and possibly endogenous ligands. Due to their location and the type of ligands that bind them, these receptors have been divided into two large groups: the TLRs of cytoplasmic membranes (TLRs 1, 2, 4, 5, 6 and 10) and the TLRs of endosomal membranes (TLRs 3 , 7, 8 and 9). TLR5 located in the basolateral membrane of epithelial cells recognizes flagellin, a structural protein that makes up flagella.
