Explanation:

Once transcription has been initiated, RNA polymerase adds nucleotides to the 3' end of the growing RNA molecule until it transcribes a termination signal or reaches the end of the gene being transcribed.

Transcription is the process by which RNA is synthesized from a DNA template. RNA polymerase, the enzyme responsible for transcription, moves along the DNA strand and adds complementary RNA nucleotides to the growing RNA molecule. The RNA polymerase adds nucleotides in a 5' to 3' direction, meaning that new nucleotides are added to the 3' end of the growing RNA molecule. During transcription, specific termination signals in the DNA sequence or the end of the gene being transcribed indicate to the RNA polymerase that it should stop adding nucleotides. In summary, RNA polymerase adds nucleotides to the 3' end of the growing RNA molecule until it transcribes a termination signal or reaches the end of the gene being transcribed.

Answer:

Dominance is when only 1 type of dominant allele is expressed. Incomplete dominance is when 2 different types of recessive alleles are received. This means neither trait is expressed, but a mixture of both traits are expressed (e.g. white and black horse have grey offspring) because both are recessive, so one cannot mask the other.

Globular proteins are usually insoluble in water.

In terms of structure, globular proteins are folded in such a way that their tertiary structures are made up of polar amino acids that are ordered on the exterior and the non-polar amino acids that are placed on the inside. Globular proteins are typically spherical in shape.

They are also referred to as sphero-proteins, and they have a mediocre water solubility. Because the non-polar amino acids on the inside of the protein globules, which are not in direct contact with water, make this type of protein soluble. Polar amino acids are present on the globules' exterior, where they interact with water to turn it into a soluble material.

Answer: Here are some examples of how the different parts of natural selection can apply to cactus populations:

1. Overproduction: Cacti are known for producing a large number of seeds. This is because cacti face a variety of challenges in their harsh desert environments, and by producing more seeds, they increase their chances of at least some of their offspring surviving adulthood.

2. Competition: To survive in their desert habitats, cacti must compete for limited resources like water and nutrients. Some cacti have evolved specialized root systems that allow them to tap into water sources that are inaccessible to other plants, giving them a competitive advantage.

3. Variation: Cactus populations exhibit a wide range of variations in their physical characteristics, such as the shape and size of their stems and spines. This variation is the result of genetic mutations and other factors, and it allows different cacti to better adapt to their specific environmental conditions.

4. Selection: In the harsh desert environment, cacti with traits that enable them to survive and reproduce are more likely to pass on their genes to future generations. For example, cacti with thicker stems or longer roots may be better able to withstand drought conditions, while cacti with larger or more brightly colored flowers may be more attractive to pollinators. Over time, these traits become more common in the population as a result of natural selection.

Explanation:

The heterokaryotic phase of a fungal life cycle is a stage in which hyphae contain two genetically different haploid nuclei.

Option C is correct. The heterokaryotic phase refers to a stage in the fungal life cycle where hyphae contain two genetically different haploid nuclei. Heterokaryosis is a characteristic feature of many fungi and plays a crucial role in their reproductive cycle and genetic diversity.

Fungi have a unique mode of sexual reproduction called plasmogamy, where two compatible hyphae fuse. During this process, the cytoplasm of two different mating types (represented by different haploid nuclei) merges, forming a heterokaryon. This heterokaryotic mycelium contains hyphae with genetically distinct haploid nuclei from the two parental strains.

The presence of genetically different haploid nuclei within the hyphae allows for genetic recombination and variation. In the subsequent stages of the fungal life cycle, such as karyogamy (fusion of nuclei) and meiosis, the heterokaryotic phase gives rise to the formation of new spores with different genetic combinations, promoting genetic diversity and adaptation to changing environments.

An ecosystem is a region in which a bubble of life is created by plants, mammals, and other organisms interacting with the weather, environment, and other factors. Abiotic elements, or non - living things components, coexist with biotic components in habitats. Ecosystem functioning is the ability of natural phenomena and elements to either directly or indirectly meet human demands for commodities and services.

Human welfare and survival rely on healthy terrestrial ecosystems because they give us access to critical goods and benefits. More than 90% of our food originates from ecosystem types, which also offer us energy, resources for building and clothing, health-related products, fresh water, and pure air.

Sex-linked traits are genes carried on the sex chromosomes, the X and the Y chromosome. Only males carry the Y chromosome, and therefore all genes on the Y chromosome are passed down to the son. Women carry two X chromosomes; therefore, sex-linked traits can be passed on from both the mother and the father.

Examples of sex-linked traits include red-green colour blindness and haemophilia.

In codominance, both alleles are expressed in the phenotype of heterozygous offspring. The human ABO blood group is an example of codominance.

There are three alleles for the ABO gene: IA, IB, and I (i is recessive to both IA and IB). If an individual is heterozygous for both the IA and IB alleles, they will express both A and B antigens on their red blood cells. If they are homozygous for either IA or IB, they will express only one antigen on their red blood cells.

Incomplete dominance occurs when neither allele is dominant nor recessive, but instead, the phenotype is a blend of both. An example of incomplete dominance is the snapdragon flower, which has a red flower and a white flower. When the red flower is crossed with the white flower, the resulting offspring have pink flowers, which is a blend of red and white. The genotype for pink flowers is Rr, where R represents the red allele, and r represents the white allele.

When two pink flowers are crossed, their offspring will have a ratio of 1:2:1 of red, pink, and white flowers.

Because the surface of a soluble protein will contain a large number of hydrophilic amino acids, the helix will be configured so that the hydrophilic side faces the protein's exterior.

The amphipathic alpha helix is a common secondary structural motif in biologically active peptides and proteins. An amphipathic helix is an alpha helix with opposing polar and nonpolar faces oriented along the helix's long axis. Amphipathic -helices on the outside and hydrophobic helices on the inside of a water-soluble globular protein. Antibacterial peptides and membrane protein domains involved in membrane environment sensing use amphipathic helices as targets. Amphipathic molecules are those that contain both polar and non-polar components. Phospholipids, for example, contain polar phosphate ""heads" and non-polar fatty acid "tails".
