The addition of buckthorn results into blocking of the light. This is an unintended consequence of adding an organism to an ecosystem. Thus, the correct option is C.

Invasive species is also called as introduced species or alien species which significantly modifies or disrupts the ecosystem in which it colonizes. Such species may arrive in the new areas through various ways such as natural migration, however they are often introduced by the activities of other species such as humans and other higher animals.

Invasive species are capable of causing extinctions of the native plants and animal species, reducing the biodiversity, competing with native organisms for the limited amount of resources, and altering habitats.

Therefore, the correct option is C.

The role of chromosomes in the process of reproduction, Chromosomes' primary purpose is to transport DNA and pass genetic material from parents to children.

Result for an image What function do chromosomes serve in the reproduction process. It is critical for DNA to be intact and be distributed equally among cells during cell division. In the vast majority of cell divisions, DNA is precisely copied and distributed thanks in large part to chromosomes. DNA may be precisely duplicated during these cell divisions thanks to chromosomes. So, once more. Our cells' nuclei include chromosomes, which enable precise DNA duplication during cell division. This guarantees that our internal processes go smoothly and effectively.

Answer:

The plasma membrane is a selectively permeable barrier that separates the cell from its environment. This means that while some substances can pass through the membrane freely, others cannot. The selective permeability of the plasma membrane is due to its structure, which is composed of a lipid bilayer with hydrophilic heads facing outward and hydrophobic tails facing inward.

The hydrophilic heads of the phospholipids are attracted to water, while the hydrophobic tails repel it. This creates a barrier that is impermeable to water-soluble substances, such as ions and polar molecules. Additionally, the phospholipid bilayer is relatively impermeable to larger nonpolar molecules, such as proteins and carbohydrates.

Small nonpolar molecules, such as oxygen and carbon dioxide, can diffuse easily across the plasma membrane due to their ability to dissolve in the hydrophobic interior of the lipid bilayer. However, larger polar molecules, such as glucose and amino acids, cannot pass freely through the membrane.

One reason for this is that the polar molecules are attracted to water, which is repelled by the hydrophobic tails of the phospholipids. This makes it difficult for the polar molecules to cross the lipid bilayer without assistance from specialized transport proteins, such as channels and carriers.

Furthermore, ions have an electrical charge that makes it difficult for them to cross the hydrophobic lipid bilayer. The charged particles are repelled by the hydrophobic tails of the phospholipids, and therefore, cannot pass through the membrane freely.

In summary, the selective permeability of the plasma membrane is due to the chemistry of the phospholipids, which create a hydrophobic barrier that is impermeable to water-soluble substances. Larger polar molecules and ions cannot freely cross the lipid bilayer because they are attracted to water and have an electrical charge that repels them from the hydrophobic interior of the membrane.

Lighting a match.

Explanation:

When the match burns it goes through a chemical change due to the materials such as phosphate, sulfur, etc. The heat then burns the phosphorous on the match's head.

Sorry if it didn't make sense.

Answer:

Lighting a match

Explanation:

Lighting a match and letting is burn is an example of a chemical change because the two reactants (fire and the match) form a new substance. Freezing water, melting ice and crushing a rock are physical changes because they only change in size, shape or form.

This commensalistic relationship demonstrates how organisms can exploit their environment and utilize other organisms to enhance their own survival and growth without causing harm or benefit to the host organism.

The plant and tree have a commensalistic relationship. In a commensalistic relationship, one organism benefits while the other is neither harmed nor benefited. In this case, the plant benefits from growing on the branches of the tall tree in the dense tropical forest because it gains better access to sunlight, which is essential for photosynthesis and growth. By growing on the tree's branches, the plant is able to reach higher above the forest floor where sunlight is often limited due to the dense canopy. This advantageous position allows the plant to thrive and maximize its chances of survival.

On the other hand, the tree is unaffected by the presence of the plant. It does not provide any resources to the plant, nor does it suffer any negative consequences from the plant's presence. The tree is simply used as a physical support structure for the plant, with no direct interaction or exchange of nutrients between them.

Answer: Those lady beetles that can eat mold and fungus will thrive while those that must eat aphids will likely die of hunger. Mold and fungus-eating lady beetles will survive to reproduce, passing along their advantageous traits. Over many generations, the likely outcome would be that the lady beetles in that environment would evolve to eat only mold and fungus.

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.

At the beginning, the frequency of the "W" allele can be calculated as follows:

Let p represent the frequency of the "W" allele. Since 60% of the moths are white (WW, Ww), the frequency of the "W" allele can be expressed as \(p^2\) + 2pq, where q represents the frequency of the "w" allele. Given that 60% of the moths are white, we can set up the equation 0.6 = \(p^2\) + 2pq.

After 3 years, the frequency of the "W" allele is 65%. Using the same equation, we can set up the equation 0.65 = \(p^2\) + 2pq. Solving these equations will give us the frequency of the "W" and "w" alleles at the beginning and after 3 years.

In a population, the frequency of alleles can change over time due to various factors such as natural selection, genetic drift, and migration. In this scenario, we are given the initial frequencies of white and black moths in the population and the frequencies after 3 years.

By using the Hardy-Weinberg equation, which relates allele frequencies to genotype frequencies, we can determine the frequencies of the "W" and "w" alleles.

The equation p^2 + 2pq represents the frequency of individuals with the "W" allele (WW, Ww), and 2pq represents the frequency of individuals with heterozygous genotype (Ww). By solving the equations, we can find the frequencies of the alleles at the beginning and after 3 years.
