Answer:

Secondary succession

Explanation:

Ecological succession is the term used to describe any series of change in the composition of an ecosystem over a particular period of time. Ecological succession is made up of two types viz: primary succession and secondary succession.

Primary succession involves the formation of a brand new ecosystem by the colonization of a barren area of land e.g bare rock, where no life existed. Secondary succession, on the other hand, is the recolonization of an area by a new set of organisms because the previously existing organisms have been wiped out by certain disasters e.g fire outbreak, hurricanes etc. In secondary succession, there is soil, which makes it possible for new organisms to sprout quickly after the calamity.

Example of secondary succession is when a fire outbreak burns the organisms in a community, allowing the root of grasses to sprout after.

All mutations will result in a change in phenotype, regardless of whether the DNA sequence, amino acid sequence, or mRNA sequence altered.

An organism's hereditary genes determine its phenotype, or physical characteristics and behaviours. Genes are specific DNA sections that encode for the creation of proteins and specify unique features.

New phenotypes are rarely created. Mutations may be inherited and hence transmitted from one person to another. If a mutation produces a novel phenotype that makes an organism more suited to a certain environment, it can swiftly change the attributes of the individuals in a species.

The pattern of evolution being described here is convergent evolution, where two unrelated species develop similar characteristics due to their adaptation to similar environments or ecological niches.

Evolution is the process of change in the inherited characteristics of biological populations over successive generations. This can occur through natural selection, genetic drift, gene flow, and mutation, and can lead to the emergence of new species over time.

Evolution is driven by various factors, including environmental changes, genetic variation, and reproductive success. It is a fundamental concept in biology and provides the framework for understanding the diversity of life on Earth.

Convergent evolution, is where two unrelated species develop similar characteristics due to their adaptation to similar environments or ecological niches.

Explanation:

To solve this problem, let's represent the heterozygous yellow-seeded plant as "Yy" and the homozygous yellow-seeded plant as "YY."

i. When crossing a heterozygous yellow-seeded plant (Yy) with a homozygous yellow-seeded plant (YY), we can set up a Punnett square to determine the possible offspring genotypes:

    Y     Y

y   Yy  Yy

y   YY  YY

ii. The genotypic ratio is 2:2 or 1:1 for the possible offspring genotypes: Yy and YY.

The phenotypic ratio is also 2:2 or 1:1 for the possible offspring phenotypes: yellow-seeded (YY and Yy).

Question 2:

To determine the probability of specific outcomes, we need additional information about the parental genotypes and their inheritance patterns. Please provide the genotypes of the true breeder from F1 and the non-true breeding yellow-seeded plant for a more accurate calculation.

Deforestation is the purposeful clearing of forested land. The answer is Decreased wildfires.

Explanation:

The clearing of trees and forest land gives it the possibility of less wildfires; If there are no trees, meaning there'd be no wildfires.

Hope this helped :)

An impact of deforestation is that it decreases wild fires.

Forest fires are quite common and often lead to very devastating effects. This is one of the negative effects of forests especially when they become dry and more prone to fire outbreaks.

So, a possible positive impact of deforestation is that it decreases the chances of the occurrence of wild fires which could distort whole ecosystems.

Explanation:

About 0.55 million or 550,000 years ago the earliest South Asian river dolphin evolved.

About 0.5 million years ago the South Asian dolphin evolved due to different environmental conditions. South Asian dolphin have very flexible necks due to no fusion of their neck vertebrae. They are using echolocation to navigate and search for prey.

Research indicates that  South Asian dolphin diverged from a common ancestor around 550,000 years ago that lives in the Indus and Ganges basins so we can conclude that the South Asian dolphin evolved around 0.55 years ago.

As a deep, continuously revolving updraft known as a mesocyclone, a supercell is a type of thunderstorm. These storms are frequently referred to as spinning thunderstorms as a result Supercells, which fall into the four categories of thunderstorms (squall line, multi-cell, and single-cell), are generally the least frequent and have the potential to be the most dangerous.

Cystic fibrosis is an autosomal recessive disorder.

Cystic fibrosis (CF) is an inherited genetic disorder that affects the lungs, pancreas, and other organs. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which is located on chromosome 7. The CFTR gene provides instructions for making a protein that regulates the movement of salt and water in and out of cells in the body. CF is inherited in an autosomal recessive pattern, which means that a person must inherit two copies of the mutated CFTR gene, one from each parent, to develop the condition. If a person inherits only one mutated CFTR gene, they are a carrier of the condition but do not have symptoms. If two carriers have a child, there is a 25% chance that the child will inherit two mutated CFTR genes and develop CF. Autosomal recessive disorders are inherited when both parents carry one copy of a mutated gene, but do not have symptoms of the disorder. In this case, there is a 25% chance that their offspring will inherit two copies of the mutated gene and develop the disorder. Since CF is inherited in an autosomal recessive pattern, it means that a child can only develop the condition if both parents are carriers or have the condition themselves.

Answer:

Explanation:

1. The exocrine function is stimulated by this hormone produced in the anterior pituitary: follicle-stimulating hormone (FSH), and produces ova (eggs) in the female.

2. The endocrine function is stimulated by this hormone in the anterior pituitary: luteinizing hormone (LH), and produces estrogen and progesterone in the female.

3. The exocrine function is stimulated by this hormone produced in the anterior pituitary: luteinizing hormone (LH), and produces sperm in the male.

4. The endocrine function is stimulated by this hormone in the anterior pituitary: follicle-stimulating hormone (FSH), and produces testosterone in the male.

1. The exocrine function of the reproductive system in females is stimulated by the hormone produced in the anterior pituitary called follicle-stimulating hormone (FSH), which promotes the production of ovarian follicles. The exocrine product in females refers to the release of eggs or oocytes from the ovaries during ovulation.

2. The endocrine function of the reproductive system in females is stimulated by the hormone luteinizing hormone (LH) produced in the anterior pituitary. LH triggers the release of estrogen and progesterone from the ovaries, which regulate the menstrual cycle, promote the development of the uterine lining, and prepare the body for pregnancy.

3. The exocrine function of the reproductive system in males is stimulated by the hormone produced in the anterior pituitary called luteinizing hormone (LH), which stimulates the production of testosterone in the testes. Testosterone is the primary male sex hormone and is responsible for the development of male reproductive organs and secondary sexual characteristics.

4. The endocrine function of the reproductive system in males is stimulated by the hormone follicle-stimulating hormone (FSH) produced in the anterior pituitary. FSH promotes the production of sperm cells (spermatogenesis) in the testes.

Overall, the reproductive system has both endocrine and exocrine functions, with the anterior pituitary gland playing a crucial role in regulating these functions through the production of specific hormones.
