Answer:

Enzymes 'reduces the activation energy' of both Exergonic and Endergonic Reaction by acting as a catalyst.

Explanation:

Enzymes lower the activation energy of both exergonic and endergonic reactions.

In biological systems, enzymes play a crucial role in lowering the activation energy of chemical reactions. Activation energy is the energy required to start a reaction. Enzymes facilitate reactions by providing an alternative pathway with a lower activation energy, allowing the reaction to occur more easily and at a faster rate. For exergonic reactions, which release energy, enzymes can help decrease the activation energy. For endergonic reactions, which require energy input, enzymes can still lower the activation energy required for the reaction to proceed.

Protozoans are not the organisms that can convert nitrogen from the air into chemical compounds that plants can use.

Bacteria and archaea are organisms that can convert nitrogen from the air into chemical compounds that plants can use. Organisms which can convert nitrogen to forms that can be used by plants such as ammonia are known as diazotrophs. Examples of such kind of organisms include Rhizobia and azospirillium.

The probability of an offspring being white in the given scenario, assuming heterozygous parents, is 25%, as calculated using a Punnett square.

The probability of an offspring being white in the given plant species, where purple (P) is dominant over white (p), can be determined by creating a Punnett square. If we assume both parents are heterozygous (Bb), the Punnett square would have one quarter (bb) representing white flowers. Therefore, there is a 25% chance that an offspring will have white flowers (rr). The other three quarters would result in purple flowers because of the dominant purple allele (P), showing a 3:1 ratio of purple to white.

Asexual reproduction is most likely to result in a rapid growth in population.

Explanation:

The type of reproduction that is most likely to result in a rapid growth in population is asexual reproduction. Asexual reproduction involves the production of offspring without the need for a mate, and it can occur through various methods such as binary fission, budding, or fragmentation. Since asexual reproduction does not require the time and energy needed to find a mate, it can lead to a rapid increase in population size under favorable conditions. For example, bacteria can reproduce through binary fission, where a single cell divides into two identical cells. Each of these cells can then divide again, resulting in exponential population growth.

The particles of the snow have kinetic energy, but being a solid, it has less kinetic energy than that of liquid water. So they move around in a place about its mean position.

Option C

Igloos are the small homes made up of snow. It used to be homes for the people living in Arctic regions in past. Now some tribes still live in these igloos, or they are made by tourists for amusements.

Snow is basically precipitation of ice from clouds. Being the solid form of water, ice has molecules more compactly arranged in its crystal structure. Thus, the molecules cannot move here and there like in fluid. But having some kinetic energy, they have certain movements i.e vibrations around its mean position.

Answer:

Controlling the proteins in an organism controls the organism's characteristics because proteins are enzymes, and enzymes catalyze and regulate chemical reactions, and therefore can control certain traits such as color, shape, or even gender.

Explanation:

Controlling the proteins in an organism regulates the organism's characteristics because translation regulates the protein expression of cells based on DNA sequences and eventually the characters are expressed.

In general, the cell has genetic contents that are expressed in terms of transcription and translation, and here these are called the fundamental processes of the cell as they are required by the cells for enzyme formation, synthesis of the receptors, membrane protein, and expression of the traits. If the translation is regulated, then the message present in the DNA is also regulated, and the protein expression can be controlled.

As a result, controlling the proteins in an organism regulates the organism's characteristics because translation regulates the protein expression of cells based on DNA sequences and eventually the characters are expressed.

Hi

As we have studied that Mitochondria is an organelle that is considered to be the power house of the cell. It is the main site where production of energy along with its supply to other organelles occur. All eukaryotic organisms contain mitochondria in their cells, however, Monocercomonoides are a newly discovered group of organisms which are eukaryotic but can happily live without the presence of mitochondria because they dont contain it in their cells.

It is believed that in Monocercomonoides, the  iron-sulfur cluster assembly pathway is replaced by cytosolic sulfur mobilization system (SUF)  pathway due to which the organism is able to easily carry out all its life processes. Evolutionary studies have also shown that previously these organisms had mitochondria but lost it during evolutionary processes.

Hope it helps!

Monocercomonoides is a single-celled organism that does not have mitochondria. However, it has adapted to carry out all the basic functions of life, including energy production, through a symbiotic relationship with bacteria.

The microorganism Monocercomonoides, an example of primitive single-celled organism, is unique because it does not possess mitochondria. Despite lacking mitochondria, it still carries out all the basic functions of life. This organism has evolved a system to perform metabolic functions typically associated with mitochondria, such as energy production, through a symbiotic relationship with bacteria. It is proof that life can adapt in the absence of what is generally considered essential cellular components. So, yes, without mitochondria, Monocercomonoides does continue to perform the basic functions of life.

Explanation:

Gregor Mendel, who was referred to as the FATHER OF GENETICS discovered the principles that governs heredity in his several experiments. He observed that, for a particular trait, an organism receives two copies of a gene called ALLELE. This two copies are contributed by each parent in gametes during reproduction. An allele is a contrasting form of a gene, that is responsible for a particular trait of that gene.

For example, the height gene possesses two alleles T and t, which is responsible for a tall and short trait respectively. In an organism, two copies od this height gene will be present either same or different depending on which allele is contributed by each parent. This explains why a diploid organism possesses two alleles for a specific gene.

One of the principles of heredity discovered by Mendel is the LAW OF SEGREGATION, which states that the alleles of a gene will separate into gamete during gamete formation (meiosis). Mendel stated that only one form of a gene (allele) will be found in each gamete. For example, in an organism with Tt genotype, the gametes produced by this organism will either contain T or t allele.

The Law of Segregation states that genetic traits are split during gamete formation, producing offspring with two copies of each gene, one from each parent. This is due to the fact that most organisms are diploid, having two sets of chromosomes from both parents.

The Law of Segregation, also known as Mendel's first law, states that during the formation of reproductive cells (eggs and sperm), pairs of genetic traits are separated or segregated from each other. This means each parent contributes one copy of the gene for each trait, resulting in the offspring having two copies of the gene - one from each parent. These copies then randomly assort into gametes, maintaining genetic variation.

As to why each organism has two copies of a gene, this is attributed to the fact that organisms are diploid. A diploid organism has two sets of chromosomes, one set from the mother and one from the father, and consequently, two copies of each gene. These genes often have slight variations, leading to diversity in traits like eye color, skin color, and so on.

In biology, a 'substrate' is a molecule that binds to an enzyme's active site and is transformed into a product through a chemical reaction. The correct answer is c) a substance that binds to an enzyme to be synthesized or digested. The process involves forming an enzyme-substrate complex where the reaction occurs.

The term substrate refers to a molecule that binds to an enzyme's active site and undergoes a chemical reaction to be converted into a product. This process typically occurs in a sequence as follows: the enzyme (E) combines with the substrate (S), forming an enzyme-substrate complex (ES); the chemical reaction occurs; and then the product (P) is released, with the enzyme itself unchanged and ready to catalyze another reaction. This makes the correct answer to the student's question:

c) a substance that binds to an enzyme to be synthesized or digested.

Enzymes act as catalysts to increase the rate of virtually all the chemical reactions within cells. They provide an active site that is specifically shaped to hold the substrate(s), creating the right conditions for the chemical reaction to occur. This is known as the lock-and-key model, where the enzyme and the substrate fit together perfectly, or the induced fit model, where binding of the substrate induces a change in enzyme shape to snugly accommodate the substrate. The enzyme-substrate complex facilitates the chemical reaction and leads to the formation of product(s), after which the substrate molecule(s) is no longer the same as it was before the reaction.
