Explanation:

The Ras superfamily of small GTPases includes the Ras homologous (Rho) protein family.

In reaction to chemical or mechanical stimuli, small GTPases, which are monomeric proteins, act as molecular switches to "on" or "off" signal transduction pathways.

Rho GTPases play an important role in cellular activities such cell migration, wound healing, cell adhesion, cell polarity, membrane trafficking, and cytokinesis because they are key regulators of actin reorganization.

All eukaryotes that have been investigated so far share a high degree of conservation among the 20 Rho GTPases, with Rho, Rac, and Cdc42 being the most prominent. Rac controls the development of membrane ruffles and lamellipodia in response to growth stimuli.

Therefore, The Ras superfamily of small GTPases includes the Ras homologous (Rho) protein family.

Answer: Before mitosis and meiosis I, DNA is duplicated.

Explanation:

Cells go through a cell cycle from the time they are created until they die. This cycle has different stages or phases, known as G1, S, G2 and M. During G1, the cell prepares to divide, producing the proteins needed. After that, it enters the S phase, which is when the cell duplicates all its DNA. Then follows the G2 phase, it also prepares for cell division. Then follows the M phase, which is the division of the cell nucleus where the two copies of its genetic material that were created during the S phase are distributed, thus forming two genetically identical daughter cells in mitosis, which is the type of cell division that takes place on somatic cells.

Prophase is the first stage of mitosis, so when the cell enters this stage, it will have twice as much genetic material (which doubles during the S phase of the cell cycle). Also, an achromatic spindle is formed, the nuclear membrane disappears and the chromosomes condense. The next stage is metaphase, where the duplicated chromosomes line up in the center of the cell. Then during anaphase, the microtubules of the cell separate the chromosomes in opposite directions, towards the poles of the cell. Finally, during telophase, the nuclear membrane is re-formed and chromosomes are already in each newly formed daughter cell. So, now each daughter cell will have its own copy of genetic material, since it was duplicated during the S-phase.

For the formation of gametes, a similar process called meiosis occurs, consisting of meiosis I (chromosomes are separated) and meiosis II (sister chromatids of the same chromosome are separated). During the S phase, before meiosis I occurs, DNA is also duplicated. The process of meiosis is similar: prophase, metaphase, anaphase, telophase (the only difference is that during prophase, an exchange of genetic material occurs between the two homologous chromosomes). Then, at the end of meiosis I, two daughter cells are formed, each of which received half of the genetic material that was duplicated in the parent cell. This is the same amount of DNA that the daughter cells get during mitosis. During meiosis II, the sister chromatids are separated, forming two more daughter cells but they will have half of the genetic material, since there is no DNA duplication between meiosis I and II. So, this division is different. However, before mitosis and meiosis I, DNA duplication takes place.

Natural selection does not produce the mutations that are in option A, as natural selection is the process by which certain advantageous traits become more common in a population over time because individuals with those traits are more likely to survive and reproduce.

Natural selection does not produce the mutations themselves. Mutations are random changes that occur in an organism's DNA and can happen for various reasons, such as exposure to radiation or mistakes during DNA replication. Natural selection acts on the variation already present in a population, selecting for traits that confer advantages in a given environment and allowing those traits to become more prevalent over time.

Plants make energy storage molecules in the form of carbohydrates, such as starch and sucrose.

Starch is the primary energy storage molecule in plants, and is synthesized in specialized organelles called amyloplasts. Amyloplasts are found in many types of plant cells, including those in roots, stems, leaves, and seeds.

Glucose molecules are then transported to the amyloplasts, where they are polymerized into long chains of glucose molecules through a process called starch synthesis. The resulting starch molecules are then stored within the amyloplasts as insoluble granules.

Starch is an important energy storage molecule for plants, as it provides a source of energy that can be used during periods of low light or other stress. When energy is needed, the starch molecules are broken down into glucose molecules through a process called starch degradation.

In addition to starch, plants also produce other carbohydrate molecules that can serve as energy storage molecules. One example is sucrose, which is synthesized in the leaves of plants and transported to other parts of the plant for storage.

Overall, the ability of plants to synthesize and store energy in the form of carbohydrates is an important adaptation that allows them to survive and thrive in a wide range of environments .

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.

Assuming a diallelic gene,

Allelic frequencies

Genotypic frequencies

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example,

Alleles          Frequencies

The nutrient which provide more energy is C. Lipids

Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.

Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.

Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.

It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.

Plants exhibit various types of tropic responses, which are directional growth movements in response to external stimuli. Here are four types of tropic responses commonly observed in plants:

1. Phototropism: Phototropism is the growth response of plants towards or away from a light source. Typically, plant shoots exhibit positive phototropism, meaning they grow towards the light, while roots exhibit negative phototropism, growing away from the light. The hormone auxin plays a crucial role in mediating phototropic responses by redistributing growth hormones unevenly in plant tissues.

2. Geotropism/Gravitropism: Geotropism, also known as gravitropism, is the response of plants to gravity. Plant roots exhibit positive geotropism, growing towards the pull of gravity, while shoots exhibit negative geotropism, growing against the force of gravity. The differential distribution of auxin in response to gravity influences the growth patterns in roots and shoots.

3. Thigmotropism: Thigmotropism is the response of plants to touch or mechanical stimuli. It involves directional growth in response to contact with solid objects. For example, tendrils of climbing plants exhibit thigmotropic responses by coiling around supports for stability and attachment. Thigmotropism is often mediated by changes in the growth hormone auxin.

4. Hydrotropism: Hydrotropism is the growth response of plants towards or away from water. Roots typically exhibit positive hydrotropism, growing towards moisture, which aids in water absorption. This response allows plants to effectively navigate their roots towards water sources and ensure their survival in water-scarce environments.

These tropic responses are critical for plant survival and adaptation to their environment. They enable plants to orient their growth towards essential resources such as light, gravity, mechanical support, and water, maximizing their chances of obtaining necessary nutrients and ensuring optimal growth and development. The mechanisms underlying these tropic responses involve complex interactions between hormones, growth factors, and environmental cues, allowing plants to respond and adapt to their surroundings.
