Answer: D

Explanation:

Explanation:

Once the fusion reactions begin, the stars exert outward pressure. As long as the inward force of gravity and the outward force generated by the fusion reactions are equal, the star remains stable.

In a stable star, the gas pressure pushing out from the centre is equal to the gravity pulling atoms inward to the centre – when these forces are equal, the star is at equilibrium.

When the force of gravity and the force of fusion in a star are equal to each other, then the life of the star increases and mass of the star is maintained.

When the inward force of gravity and the fusion reactions are equal to each other, the star remains in stable condition. There is direct relationship between force of gravity and fusion reaction. When the force of gravity compresses the core of a star, the temperature increases to a higher limit. At last, the temperature is high enough that the star initiates fusion reaction in which fusing hydrogen into helium occur. When the outward pressure that is produced by fusion energy, it balances gravity which results in the formation of a stable star.

So we can conclude that If the force of gravity and the force of fusion within a star are equal to each other, the star’s life increases and mass of the star is maintained.

The following three results are possible if a mutation in the gene that codes for the G subunit causes it to lose its GTPase activity:

3. The signaling pathway could be activated for an extended period, possibly resulting in undesirable cell proliferation.

4. The concentration of cAMP in the cell would be continuously elevated.

6. Gα would be activated for an extended period.

The hydrolase enzymes known as GTPases attach to the nucleotide guanosine triphosphate (GTP) and hydrolyze it to produce guanosine diphosphate (GDP). The highly conserved P-loop "G domain," a protein region shared by numerous GTPases, is where GTP is bound and hydrolyzed.

The components of the Gα subunit include Gs, Gi, Gq/11, and G12/13. Adenylyl cyclase activity is regulated by the Gs and Gi families, whilst the Gq family promotes PLC-, and the G12/13 family can activate small GTPase families. The signaling pathway could be active for a long time, which could lead to unfavorable cell growth. The amount of cAMP in the cell would constantly increase. G would be turned on for a long time.

Fatty acids & amino acids are molecules that can be catabolized such that the resulting carbon can be used to create ketone bodies.

The metabolic process known as ketogenesis results in the production of ketone bodies in the body. Ketone bodies are produced as a substitute for carbs as an energy source. Ketone bodies form in diabetic cells as a result of their inability to use glucose as an energy source.

The main source of ketone molecules is the beta-oxidation of fatty acids, which produces acetyl CoA. Ketone bodies are created by breaking down fatty acids into two-carbon units. Therefore, fatty acids are the main source of ketone bodies in the cell, whereas ketogenic amino acids only cause ketone body production.

Two amino acids that promote ketosis are lysine and leucine. Isoleucine, phenylalanine, and tyrosine are among the amino acids that induce ketosis.

Answer: C. smaller than bacteria

Explanation: Parasites are typically seen with the bare eye (not all, but many) or with a very low magnifying microscope, and dimes are obviously able to be seen without magnification. Protons are extremely small (in the femtometer region), and bacteria are in the micrometer region. Viruses are typically in the nanometer region, so they are larger than protons but smaller than bacteria.

Ribosomes and Endoplasmic Reticulum (ER) work together to synthesize proteins.

Ribosomes are the nucleoproteins That are present ether in the cytoplasm of the cell or attached to the ER. Ribosomes are also referred as protein factory because they play a central role in protein synthesis. Ribosomes can be of two types: 70S and 80S.

ER is of two types: Rough ER and Smooth ER. Rough ER contains ribosomes attached to it. RER also plays major role in protein synthesis. It helps in the modification and transport of the synthesized protein. The proteins formed in the RER are the secretory proteins.

There are several epithelial tissues in the human body. They make up the majority of the tissue in the body. Safeguarding, secretion, ingestion, excretion, purification, transport, and sensory reception are just a few of the many tasks they carry out.

In epithelial tissue, there is relatively little intercellular matrix and the cells are closely packed together. 

Each epithelium has two surfaces: one would be revealed to the outside environment, which may include liquids like those found in the circulatory as well as urinary systems,  also gases such as in the respiratory system, or semisolids like those found in the digestive system.

During photosynthesis, carbon is transferred from an abiotic source to living things.  As a result of cellular respiration, carbon is transferred from living things to an abiotic reserve.

Every trophic level results in an exponential increase in DDT levels. Osprey are at the greatest trophic level in this group because they are the tertiary consumers, and their tissues have the highest DDT contents.

pH values for catalase - Each enzyme has a specific pH range within which it functions best. Catalase only functions in people between a pH of 7 and a pH of 11. The enzyme loses its structure and becomes denaturated if the pH is more than 11 or less than 7, respectively.

Each enzyme has a best operating temperature, as well as every enzyme has a best operating pH. For instance, the digestive system's trypsin and pepsin enzymes sever long protein chains in meals into smaller pieces, such as peptide chains or individual amino acids. The stomach's extremely acidic environment is where pepsin operates. Its ideal pH is at around 1.5.Trypsin, on the other contrary, functions in the intestinal tract, which has certain areas with a pH of about 7.5. The ideal pH for trypsin is around 8. Amino acids with opposite charges will attract within the enzyme molecule. This affects how the enzyme molecule folds, how it is shaped, and how the active site is shaped. The charge on the molecules of the amino acids will change when the pH changes. The volume of oxygen evolved over a five-minute period was plotted versus the relative reaction rate. Every time the experiment was conducted, the control displayed the same enzyme activity. Up until the optimal pH level, which is around 6.3, the relative reaction rate went up with pH; however, as pH climbed, the rate of reaction declined.

A high mass star will not be able to generate enough energy beyond the silicon fusion cycle to stop its collapse because iron fusion doesn't generate excess energy and gas pressure to prevent the core from collapsing. Instead, it requires additional energy.

All stars generate energy by nuclear fusion at the core of the star. Fusion starts form the lightest element, hydrogen. Two hydrogen atoms fuse to form helium atoms, releasing vast amounts of energy in the form of radiation, light and heat. After a while the amounts of hydrogen atoms in a star starts to reduce, while helium becomes predominant.

Helium fusion requires way more heat and pressure to occur than hydrogen fusion. This is because the heavier the element, the greater the temperature and pressure needed to fuse it. Low mass stars are unable to produce such high amounts of energy, so they just become white dwarfs after using up all their hydrogen, but the story is different for high mass stars.

A massive star is able to generate enough heat and pressure to fuse helium. In fact, it is so hot that it is able to fuse the product of helium fusion - carbon into oxygen, oxygen into neon and phosphorus, and finally silicon is formed, which also fuses to form iron. However, beyond the silicon fusion, iron doesn't undergo any nuclear fusion. This is because the energy needed to fuse an element as heavy as iron is just too much for any star to produce no matter the size. Iron fusion also doesn't produce any gas pressure or excess energy to sustain the core; thus, the star eventually runs out of energy and collapses, leading to a supernova.
