Answer:
Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.
Explanation:
The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.
So, we need to plant more trees that act as the natural habitat for the wildlife and preserve and conserve them in parks and sanctuaries which will help reduce the impacts of global warming and climate change. We should not kill any animal.We should decrease the use of plastics.why is it impossible to eradicate malaria

false it produces more ATP than any of the other respiration reactions
Glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.
What is ATP?ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. It is a byproduct of the photophosphorylation, cellular respiration, and fermentation processes and serves as the primary energy currency of the cell.
Glycolysis is defined as a chain of events that convert glucose into two pyruvate molecules, which have three carbons each. Glycolysis is a cytoplasmic process that breaks glucose down into two molecules with three carbons apiece and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.
Thus, glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

Give a reason why lack of roughage in diet often lead to constipation?
Answer:
Roughages increase fecal volume and promote peristalsis
Explanation:
Constipation refers to the condition in which bowel evacuations occur infrequently, leading to health problems. Some of the most common causes of constipation include 1-insufficient intake of dietary fibers or roughages, 2-poor hydration, 3-lack of physical exercise, 4-abuse of laxatives, etc. Dietary fibers are divided into two classes based on their water solubility: soluble and insoluble. These fibers represent the part of plant foods that the body can't digest, which absorbs and retains water (soluble fibers) as foods pass through the bowel and create bulk (insoluble fibers), thereby leading to regular bowel habits.

Why is it essential for SARS-CoV2 RNA be translated on ribosomes before it can be replicated?
The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome. The protein inserts its C-terminal domain into the mRNA channel, where it interferes with mRNA binding. We observe translation inhibition in the presence of Nsp1 in an in vitro translation system and in human cells.

Answer:
the answer is (C) haploid + haploid = diploid
Explanation:
edge 2021
Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).
What is Fertilization?
Fertilization is defined as the process in which two gametes where one male and one female first form a zygote and then lead to the development of an embryo.
These germ cells are cells that give rise to gametes – either egg cells that are female gametes or sperm cells that are male gametes.
These germ cells are the only cells that can undergo both mitosis and meiosis. These are the diploid cells present in the gonads. After meiosis, haploid gametes are produced. In fertilization two haploid gametes fuse (n+n) and form a diploid zygote (2n)
Thu, Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).

Explanation:
Sometimes the most practical way to do an experiment is not to perform it in an animal, but to look at cell responses in culture. Cells from mice, humans, and other mammals have been used to establish cell culture lines that have been very important for research. You are studying a novel water-soluble mouse hormone. You know cell culture can be a practical model to reveal protein function, so you apply the hormone to yeast cells, but nothing happens. What is a likely explanation for why nothing happened in your experiment
Answer:
Yeast cells likely do not have receptors that bind to this specific water-soluble mouse hormone
Explanation:
Receptors are molecules capable of binding specific signaling molecules (i.e., ligands). For example, steroid receptors can only bind to specific steroid hormones (e.g. estrogen, progesterone). Plasma membrane receptors are protein receptors that bind to water-soluble ligands. These receptors are embedded in the cell plasma membrane and usually contain several transmembrane domains. Examples of cell membrane receptors include G protein-coupled receptors (GPCRs), enzyme-linked protein receptors and ion channel receptors.

Aquaporins result in a combination of positive charges intracellularly and negative charges extracellularly
What are Aquaporins?
Aquaporin is a group of membrane proteins found in cell membranes and selectively permit water to pass into and out of the cell. Also known as water channels, aquaporins are integral membrane pore proteins. Aquaporins are found in plants, bacteria and animals. They are observed in the vacuolar membranes and plasma membranes. The basic function of most aquaporin is to transport water across cell membranes in response to osmotic gradients created by active solute transport. Aquaporins enable passive transport which means they allow the movement of molecules across a cell without using energy.

define and describe osmosis
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
Give the functions of the following parts of the respiratory system - Nostril - trachea - bronchiole - alveoli - pharynx - larynx - lungs - ribs - diaphragm
Answer:
Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.
Nostril: To warm air on inhalation and remove moisture on exhalation.
trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.
alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.
pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.
larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
lungs: To help oxygen from the air we breathe enter the red cells in the blood.
ribs: To aid respiration and help protect the lungs.
diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.
