A group of environmental activists in West Virginia wants to save a large forest , the act that help them in activity is Eastern Wilderness Areas Act.

Option C is correct.

The Act established 16 brand-new wilderness areas in the Eastern United States, including 207,000 acres (84,000 ha) of wilderness on 13 states' national lands. Despite the fact that it was initially untitled, the bill endorsed by Portage has come to be known as the Eastern Wild Regions Act.

Environmental activists develop strategies to raise awareness or produce solutions that directly address the problem after determining issues that threaten the planet's viability—from local to global issues. The actions of individuals or groups that help or protect the environment are what are meant to be referred to as "environmental activism." The movement's participants identify issues that threaten the planet's survival, from local to global issues, and then devise strategies to raise awareness or come up with solutions that directly address the issue.

True, the thread-like objects in the nucleus are the chromosomes.

One could consider chromosomes as tiny packages safeguarding the blueprints responsible for shaping an organism's physical traits. These soft, slender strands represent a combination of both DNA and protein molecules found throughout every cell within our bodies' nuclei; together they act to store and distribute essential genetic information from one generation to another successfully.

Genes constitute individual pieces within each chromosome- segments containing sequences made up entirely by specific arrangements of nucleotides transferred through reproduction that ultimately determine inherited biological features unique to each organism type. Despite sharing similar functions amongst different living beings, we must note that the number of chromosomes within each cell can vary widely.

Answer:

When a child is formed, they get half of their genes or traits from each parent. These genes are like tiny sets of instructions that determine things like a child's hair color, eye color, and height. Each parent contributes their genes through their sperm or egg. For example, if a parent has brown eyes, they will contribute a gene for brown eyes to their child. If the other parent has blue eyes, they will contribute a gene for blue eyes to the child.

However, not every trait from each parent will appear in the child. Some traits are dominant, which means they will show up even if only one parent contributes that gene. Other traits are recessive, which means they will only show up if both parents contribute that gene. And sometimes, traits can be a combination of both parents' genes.

In terms of human reproduction, we are the result of sexual reproduction. This means that an egg from a female and a sperm from a male combine to form a zygote, which eventually develops into a fetus and then a baby. Each parent contributes half of their genetic material to the child, resulting in a unique combination of traits.

Explanation:

Sana makatulong

A child inherits traits from both parents through a process known as genetic inheritance. Humans have two sets of chromosomes, one set inherited from the mother and one from the father. Each set contains genes that determine various traits such as physical characteristics, eye color, hair type, and many others.

Each parent contributes their traits to the child through the genes on their respective chromosomes. Traits are typically determined by the combination of alleles. For example, if the mother has a gene for brown eyes and the father has a gene for blue eyes, the child may inherit one allele for brown eyes and one allele for blue eyes.

During reproduction, the parents' genetic material combines through the process of fertilization. The father's sperm carries genetic information in the form of chromosomes, while the mother's egg also contains chromosomes. When the sperm fertilizes the egg, their genetic material combines to form a unique set of chromosomes in the resulting zygote.

Due to the fact that a pH of 7.9 is still considered slightly alkaline, the term acidification can be misleading. However, as the graphs in these three locations show, as CO2 levels rise, the pH decreases, moving toward the acidic end of the pH scale.

Ocean acidification occurs in different parts of the world. I disagree with the statement that "ocean acidification" is inaccurate because it occurred as a result of increased carbondioxide gas release in the atmosphere, which is dissolved in the ocean or sea water.

When carbondioxide gas is dissolved in water, it produces carbonic acid, which changes the pH of the ocean water, which tends to be acidic, so ocean acidification occurs in various parts of the world, in my opinion.

Many marine species are expected to suffer as a result of ocean acidification. This could have an impact on marine food chains and human food supply. Acidification may also reduce storm protection from reefs, tourism opportunities, and other intangible benefits.

The pancreas is no longer able to create insulin in people with type 1 diabetes.

When you have type 2 diabetes, your pancreas initially generates insulin, but your body's cells can't effectively utilize it. Insulin resistance is what causes this.

Your pancreas naturally produces the hormone insulin, which regulates how your body consumes and stores blood sugar (glucose). It works like a key to letting glucose into your body's cells.

A crucial component of metabolism is insulin. Your body couldn't function without it.

Your pancreas releases insulin when you eat to assist your body in converting glucose, a form of sugar contained in carbohydrates, into energy. It also facilitates energy storage.

Insulin-dependent diabetes or juvenile diabetes were previous names for type 1 diabetes. Though it typically appears in kids, teens, and young adults, it can occur at any age.

About 5–10% of patients with diabetes have type 1 diabetes, which is less frequent than type 2.

Answer: the way alleles are organized

Explanation:

Genotype is the genetic makeup of an organism that determines what forms of genes exist within it.

The offspring resulting from pollinating a flower of one plant with the scraped-off flower of another plant will be genetically distinct from their parent (option c) .

When a botanist scrapes off a flower from one plant, it collects the pollen from that flower.

The botanist then uses the collected pollen to pollinate the flower of another plant, transferring the genetic material from one plant to another.

Pollination is the process by which pollen grains are transferred from the male reproductive organ (stamen) to the female reproductive organ (pistil) of a flower.

During pollination, the pollen carries the genetic information (DNA) of the plant it came from.

When the pollen reaches the stigma of the second plant's flower, it fertilizes the ovules and initiates the formation of seeds.

The seeds that develop from this cross-pollination will contain a combination of genetic material from both parent plants.

Due to the mixing of genetic material, the offspring will be genetically distinct from either parent.

The specific characteristics of the offspring will depend on the traits inherited from each parent.

Genetic recombination and variation occur during sexual reproduction, resulting in offspring that exhibit a range of genetic traits.

Therefore, based on the process of sexual reproduction and genetic mixing through pollination, it can be concluded that the offspring will be genetically distinct from their parent.
