VALUE BASED QUESTION (Write in about 50-100 words)
Consider the following two cases:
(i) A forest that is rich in biodiversity sees a decline in the animal population and clearing of a large part of the forest. The Government declared it as a biodiversity hotspot and the forest regained its species richness in few years.
(ii) A lake that is rich in marine fishes sees a decline in its species population due to over harvesting. The people living in the area made the lake a sacred grove and started worshipping it. The species population of the lake again became normal.
Answer the following questions based on the above information:
(i) Which values are being promoted in the above cases? (ii) Suggest some ways in which you can contribute to this concern. (iii) What would have been the effect if the forest was not declared a biodiversity hotspot?
Answers
In this case, the values promoted are conservation. By creating awareness about biodiversity, we can contribute to the cause. The species of forest would have gone extinct if it was not discovered a biodiversity hotspot.
What is a biodiversity hotspot?Biodiversity is defined as the variety of plants and animals that are found in a particular area and is referred to as the biodiversity of that area. Species evenness and species richness are major components of biodiversity.
Biodiversity hotspots are the regions of high endemic species richness. For an area to be classified as a biodiversity hotspot, there are two criteria. These are -
1500 species of vascular plants.30% or less of the original habitat.Therefore, conservation values are being promoted in this case

Without getting into detail of the works by Sidney Fox and Bernal on polymerization, explain why their work matters to the theory of abiogenesis?
Answers
Live plant matter on Earth is created by the creation of chemicals derived from deceased plants and animals (abiogenic)
Abiogenesis, on the other hand, is the process of some proteins aggregating on early Earth as a result of an external energy source.
In order to support their hypothesis, Haldane and Oparin offered the above proposal based on an experiment conducted by Stanley Miller. The building blocks, including as amino acids, nucleotides, and sugars, were said to originate in a primordial, reduced environment that contained high-voltage sparks, water, methane, h2o, and ammonia.
Then, bigger organic macromolecules are created as a result of polymerizing all the constituent parts.
When amino acids splash over a dry, hot environment while being exposed to cyanide and clays, according to experiments conducted by Sidney Fox and Bernal, polymer of amino acids occurs.
On the basis of the Stanley Miller experiment, Haldane and Operin's suggestions regarding the idea of abiogenesis are also supported by this experiment.

The runner’s body has failed to perform cellular respiration.
The runner’s cells are relying completely on aerobic respiration.
The runner’s muscles have accumulated carbon dioxide.
Answers
Answer:
A
Explanation:
Just did the Unit Test
When the body is subjected to vigorous exercise, lactic acid tends to build up in the muscles, hence, the most probable explanation for the fatigue felt by the runner is the accumulation of lactic acid in the runner's muscle
When the body is subjected to vigorous exercise such as running several miles as performed by the subject in the question, lactic acid accumulates temporarily in the muscles. This temporary build up of lactic acid in the muscles causes feeling of fatigue or weakness as the body tends to become short of oxygen required to breakdown the glucose in the blood.Therefore, the runner most probably has accumulated lactic acid in his muscles.

Which of the following about the action potentials of skeletal, contractile myocardium, and autorhythmic myocardium is TRUE? a) only the autorhythmic myocardium has threshold. Ob) K+ efflux causes the
Answers
K+ efflux causes the repolarization phase of the action potentials in skeletal, contractile myocardium, and autorhythmic myocardium. The repolarization phase of action potentials in both skeletal and myocardial cells, including contractile myocardium and autorhythmic myocardium, is primarily driven by potassium (K+) efflux.
During the depolarization phase of an action potential, there is an influx of sodium ions (Na+) into the cell, leading to the rapid rise in membrane potential. This depolarization phase is followed by the repolarization phase, where the cell returns to its resting membrane potential.
In the repolarization phase, K+ channels open, allowing K+ ions to move out of the cell. This efflux of K+ ions causes the cell to become more negatively charged again, leading to repolarization and restoration of the resting membrane potential. This process prepares the cell for another action potential.
This repolarization mechanism holds true for both skeletal muscle cells and contractile myocardium cells. In skeletal muscle, the repolarization phase allows the muscle fiber to relax and reset for the next contraction. Autorhythmic myocardium, also known as the pacemaker cells of the heart, generate spontaneous action potentials that control the heart's rhythm. These cells also undergo depolarization and repolarization phases, with K+ efflux playing a significant role in the repolarization process.
Therefore, the statement "K+ efflux causes the repolarization phase of the action potentials in skeletal, contractile myocardium, and autorhythmic myocardium" is true.

where is leptin produced and what is it's function? leptin is a protein produced by adipose (fat) cells. it signals adequate fat storage and leads to a reduction in hunger and eating. leptin is produced by the small intestine in response to food and functions to reduce hunger. leptin is a hormone made by the liver. it stimulates hunger and eating in response to reduce nutrient availablity. leptin is produce by the pituitary gland and functions to reduce overeating by promoting satiety.
Answers
One of the hormones with a direct relationship to body fat and obesity is leptin. transmits signals to the hypothalamus in the brain after being released from fat cells in adipose tissues. Not just from one meal to the next, but throughout time as well, the leptin hormone regulates and modifies food intake and energy expenditure.
The hormone leptin, which is primarily produced by adipocytes and enterocytes in the small intestine, aids in the regulation of energy balance by preventing hunger. This reduces adipocytes' capacity to store fat. The LEP gene produces leptin. Leptin mediates feeding through acting on dopaminergic neurons in the ventral tegmental area, cell receptors in the arcuate and ventromedial nuclei, as well as other areas of the hypothalamus.
Leptin is thought to serve a variety of physiological roles, including the regulation of fat deposits, as shown by the fact that it is synthezised in many cell types outside fat cells and that leptin receptors are present in many cell types other than hypothalamic cells.
The full definition of several of these additional responsibilities is still pending.

how does plant makes their own food
Answers
What is it?
Photosynthesis is the process in which plants make food for themselves by a constant growth cycle. Photosynthesis benefits us and the plant. Photosynthesis helps us by providing the release of oxygen into the air, and the plant gets food. Plants are autotrophs, I will explain what those are in a moment.
What are autotrophs?
Autotrophs are organisms able to create their own food for themselves through a process or cycle. Autotrophs are interesting creatures. They can create this food for themselves out of the substances within our environment, such as carbon dioxide.
Process of photosynthesis
Plants absorb CO2 and H2O from the soil and air. The water inside the plant cell is oxidized, which causes it to lose electrons. Since the CO2 is reduced, this water, at the same time, gains electrons. The water transforms into oxygen, which the plant releases during this process, and the CO2 turns into glucose, which is major for the energy needed across the plant cell.

if a sperm nucleus is injected into an oocyte, what steps of gametogenesis and conception are bypassed?
Answers
Sperm head development and activation, oocyte development, and formation of polar bodies
Gametogenesis includes spermatogenesis & oogenesis. It includes three phases - Multiplication Phase - In this phase, the diploid germ cell divides by mitosis to form diploid oogonia in oogenesis & spermatogonia in spermatogenesis.
Growth Phase - This phase involves only growth in size. It is the longest phase. It results in the formation of the primary oocyte in oogenesis and primary spermatocyte in spermatogenesis.
Maturation Phase - This phase involves meiotic division and it is divided into two phases -
Maturation - I - The diploid primary oocyte/ spermatocyte divides by meiosis-I to form two haploid secondary spermatocytes in spermatogenesis and in oogenesis one secondary oocyte & one polar body is formed.
Maturation - II - In spermatogenesis, the two secondary spermatocytes divide by meiosis-II to form four haploid spermatids which finally convert into four haploid sperms. In oogenesis, the secondary oocyte divides by meiosis-II to form one haploid ootid and one haploid polar body-II.
