klasskru [66]3 years ago
4 0

Explanation:

The structure of an ecosystem is a group of the organisms and physical features of environment including its own amount and its distribution of nutrients in a particular habitat. It helps to also provide info regarding the range of climatic conditions that try to harm the ecosystem in the area.

prohojiy [21]

Answer:

The statement that best explains the mechanisms of inheritance of gene "The allele for blue is an X-linked dominant allele because there are no blue male offspring in cross 2."

Explanation:

The mechanism for inheritance of gene is the condition, in which the mutation when happens in one allele and cause the effect in the relevant phenotype. Similar inheritance will also be seen when the mutated allele will produce new type of the protein which will have deletorious effect on the normal function of the cell. In case of the single gene, autosomal dominant, autosomal recessive, X-linked dominant, X- linked recessive and mitochondrial are modes of inheritance.

mr_godi [17]

Character displacement differs from resource partitioning because character displacement  is directly linked to the evolution of genotypes that have allowed alternate resource use

<h3>What is genotypes ?</h3>

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype. The number of copies of each chromosome found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene.

In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two alleles for each gene. Homozygous refers to a genotype when both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.

Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.

topjm [15]

Answer:

The description is provided in the explanation section below

Explanation:

ALTERNATION OF GENERATIONS is a unique phenomenon whereby certain organisms switch between a diploid state and a haploid state in their reproductive life cycle. It is a feature of plants (higher and lower).

A plant is a diploid organism (2n) i.e. contains two set of chromosomes. This diploid state of the plant is called the SPOROPHYTE. The diploid sporophyte (2n) of a plant undergoes meiotic division (reduction division) to produce haploid spores. These haploid spores germinates and grows via mitosis (duplication division) to form the haploid GAMETOPHYTE.

The haploid gametophyte (n), via structures called GAMENTAGIA, produces haploid gametes. The male gametophyte produces male gametes (sperm) while the female gametophyte produces female gamete (egg). These haploid gametes eventually fuse in a process called FERTILIZATION to produce a diploid ZYGOTE (2n) i.e. sperm (n) + egg (n) = zygote (2n). The ZYGOTE undergoes series of mitotic divisions (growth) to form the diploid SPOROPHYTE (2n) of the plant. The cycle restarts again in that order, hence it is called ALTERNATION OF GENERATIONS.

N.B: Mitosis maintains the number of chromosomes of the parent cell while meiosis reduces the chromosomal number of the parent cell by half.

4. How can subsidence lead to the formation of sedimentary rock?
S_A_V [24]
When the ground subsides it can become lower than the surrounding terrain, forming a basin.

Since water, which carries sediment, flows downhill, sediment will collects in these basins.

If enough sediment collects, compaction and cementation will turn it into sedimentary rock.
