Answer:

A

Explanation:

Channel and carrier proteins are both considered facilitated diffusion. We also know that materials do not like to go against the concentration gradient so we can eliminate B.

Answer:

Diploid

Explanation

Among sexually reproducing organisms, the number of chromosomes in the body (somatic) cells is diploid (2n; a pair of each chromosome)

Mitosis produces 2 diploid cells.

Answer:

A competitive firm’s marginal revenue always equals its average revenue and price. This is because the price remains constant over varying levels of output. In a monopoly, because the price changes as the quantity sold changes, marginal revenue diminishes with each additional unit and will always be equal to or less than average revenue. A conclusion is the last paragraph of your essay, or, if you’re writing a really long essay, you might need 2 or 3 paragraphs to conclude. A conclusion typically does one of two things—or, of course, it can do both: Summarizes the argument. Some instructors expect you not to say anything new in your Hydro-power is the energy harnessed from running water-streams, rivers or any other artificial or natural water flow. It is one of the oldest method of energy production. Even in the medieval period, people used to derive energy from water wheels. The contribution of hydel power in the world en­ergy production scenario is immense and ever-increasing.

Hydro-electricity now contributes nearly 7% of global electricity production when only 15.3 percent of the global exploitable hydro-electric potential is being used. Ever increasing awareness of ecology and social costs of hydro-plant construction failed to debar the increas­ing use of hydro-electricity.

Explanation:

this is just what is in my mind

Answer:

Introduction/Hook- Begin with a question based on the article. Give at least with three reasons of you position. Give your thesis.

Body- Explain three reasons of why is good or bad idea to invest in hydroelectric energy.

Provide evidence and explain it in each paragraph.

Conclusion- This the last chance to convince the reader to agree with your statement. Do not rewrite the reasons. You can restate your thesis.

If it is an argumented essay, provide the counterclaim (the other side opinion)and prove them that your statement is better.( this usually is the last paragraph of the body)

Answer:

b.) nondisjunction......

A woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.

Chromosomes may be defined as tiny, threadlike structures inside most cells of every organism, or living thing which carries the genetic information.

The presence of 3 X chromosomes indicates the condition of trisomy which arises as a result of non-disjunction.

When homologous chromosomes fail to separate at meiosis resulting in a germ cell containing 24 chromosomes rather than 23.

Therefore, a woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.

Answer:7 is 5

not sure what 9 is

Explanation:

Answer:

No cells are produced.

Explanation:

If the S phase of cell cycle did not work properly, the cells produced are abnormal or no cells are produced because no extra copy of chromosomes are present for cell division. If there is no extra copy of chromosomes is present in the cell, the cell will not go to the G2 phase and as a result the cell cycle is remain incomplete. So that's why we can say that no cells are produced if S phase did not work properly.

Answer:

Water, carbon dioxide,oxygen and some other substances can pass through the cell membrane because oxygen and carbon dioxide moves across the cell membranes from a simple diffusion a process that does not require any energy input and is driven by differences in concentration on the other side of the cell membrane.

Answer:

maternal mtDNA

Explanation:

While nothing but the haploid nucleus remains of the sperm during fertilisation, the ovum still has its mitochondria and other organelles. Mitochondria are capable of division and will divide according to cell's needs.

So it is the maternal mtDNa that gets passed on. Spontaneous mutations can happen at any point ofcourse and get passed on in the same way.

Explanation:

The symbiotic relationship between orchids and trees is called commensalism, which means the orchid and tree host depend on eachother to survive.. The orchid provides the tree with sunlight, (nutrients created by sun- exposure).

the tree provides a solid base for the orchid to climb up the tree, they are dependent on eachother for survival...

The type of symbiotic relationship between orchids and forest trees is commensalism.

Commensalism is a relationship in which one species benefits while the other is neither helped nor harmed. In this case, orchids benefit from the elevated position and access to sunlight provided by the trees, while the trees are neither helped nor harmed.

The effect of this interaction on orchids is that they are able to thrive in a challenging environment where they would not otherwise survive. The effect on forest trees is neutral, as the orchids do not harm or compete with them for resources. However, the presence of orchids on the tree bark may attract pollinators or other organisms, which could potentially benefit the trees indirectly.
