Explanation:
the cell walls of fungi are made of chitin, not cellulose. Also, fungi absorb nutrients from other organisms, whereas plants make their own food. These are just a few of the reasons fungi are now placed in their own kingdom.
Ecosystems are dynamic; they are always changing, and most changes occur naturally over time. However, natural disasters and human activities may dramatically alter an ecosystem.

How are the light-capturing reactions and the calvin cycle interdependent on each other?.
Answer:
The Calvin cycle requires the ATP and NADPH produced in the light-capturing reactions, while the inputs to the light-capturing reactions are regenerated by the Calvin cycle.
Explanation:
This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
10) A species is considered introduced when its transport into an area outside of its native range is human mediated. Introductions by humans may be either intentional or accidental. In the U.S. many
economically important species have successfully been introduced and managed: they have not become invasive species. Identify the statement that is NOT CORRECT regarding the positive effects
of
introduced species
A) All Livestock species except the American bison and the turkey are introduced species to North America.
B) Thomas Austin, a British landowner had rabbits released on his estate in Victoria, Australia because he missed hunting them.
Eliminate
Species, such as the wolf, are reintroduced because it has become locally endangered or extinct and this is done in the interest of conservation
D) Many plants, such as the Norway maple and the Japanese maple, have been introduced with the intent of aesthetically improving public recreation areas of private
properties
Answer:
The introduction of new species in the new area make the specie invasive if there is no predator is present in that ecosystem because the predator helps in the controlling of the population of that invasive species. The big example of invasive species is rabbit in the Australia where rabbit become invasive when there is no predator is present in that region so they increase in population and destroy all vegetation of that region. So if there is no predator of a newly introduced species, it become invasive in future.

Passage
A group of students is studying the types of plants that grow in a meadow
next to their school. The meadow is mowed regularly, but it does not get any
water other than rainfall. The meadow has several kinds of plants that are
typically found in a grassland ecosystem. The plants include grass and clover.
But there aren't any trees. The meadow has insects, including ants.
Earthworms live in the soil. Garter snakes and mice also live in the meadow.
The ecosystem in the meadow consists of the biotic factors such as grass, Garter snakes, and mice, as well as the abiotic factors such as sunlight and water.
What is an ecosystem?A ecosystem is a self-supporting system consisting of biotic and abiotic factors interacting together to support life.
The biotic factors refers to all living things in that ecosystem such as plants and animals.
The abiotic factors are the non-living components of the ecosystem such as sunlight, water, soil, air, etc.
Therefore, the ecosystem in the meadow consists of the biotic factors and the abiotic factors.

can someone explain how impulses r transmitted at synapses
Impulses are transmitted through the help of neurotransmitters at the synapses.
What are synapses?Synapses are spaces at the neuronal junctions which are located between the muscle and the nerve cell.
Impulses arriving from a nerve cells usually crosses these spaces to the next nerve or muscles.
The generation of action potentials leads to the release of chemical messengers called the neurotransmitters.
These chemicals diffuse across the synapse (the gap between the two neurons).
The chemicals bind with receptor molecules on the membrane of the second neuron.
Therefore, Impulses are transmitted through the help of neurotransmitters at the synapses.

If a cell had 12 chromosomes at the beginning of meiosis ii, how many would each daughter cell have after the completion of meiosis ii? 12 6 18 24
If a cell had 12 chromosomes at the beginning of meiosis II, each daughter cell would possess 12 chromosomes after the completion of meiosis II as well.
What do you mean by Chromosomes?Chromosomes may be defined as thin thread-like structures that contain genetic information associated with organisms.
After the completion of meiosis II, the four daughter cells are formed which are haploid in nature and contain a single copy of each chromosome.
So, if 12 chromosomes are there at the beginning of meiosis II, all the resultant four daughter cells possess a single copy of all the 12 chromosomes.
Therefore, it is well described above.

Why if marathon runners start too quickly are unlikely to finish the race
Answer:
The marathon runners likely will get too winded out!
Explanation:
A marathon is a long-distance dash (roughly 26.2 miles!) If you walked that distance at an average speed it will take roughly you 8 and a half hours. Think about it let's say the runners dashed the first 5-10 miles as fast as they can, just imagine how tired they would be. They might faint or something else that might make the runners have to stop running the marathon. If the runners ran the marathon at more of a jogging pace, it's less likely for them to faint making it more likely for the runners to finish the race!

Answer:
Copernicus

The answer is Copernicus.
Explanation:
Nicolaus Copernicus was a Renaissance polymath, active as a mathematician, astronomer, and Catholic canon, who formulated a model of the universe that placed the Sun rather than Earth at its center. In all likelihood, Copernicus developed his model independently of Aristarchus of Samos, an ancient Greek astronomer who had formulated such a model some eighteen centuries earlier.Which biome would be found furthest north?

A. I only.
B. II only.
C. I and II.
D. II and III.
note: explain why?
A phytohormone Auxin is synthesized in the meristematic tissue of the plant shoot and root.
What do you mean by Meristematic tissues?Meristematic tissues may be defined as cells of plants that are competent for dividing indefinitely and giving rise to similar cells or to cells that differentiate to produce the definitive tissues and organs.
Auxin promotes stem elongation. It is synthesized in the area of shoot and root apical meristem that initiates the development of leaves and roots respectively.
Therefore, a phytohormone Auxin is synthesized in the meristematic tissue of the plant shoot and root.

What evolutionary mechanism most likely has contributed to this decrease in the population’s genetic diversity?
a. Gene flow
b. Mutation
c. Genetic drift
d. Recombination
The evolutionary mechanism that most likely has contributed to this decrease in the population’s genetic diversity is genetic drift.
What is genetic drift?Genetic drift is an overall shift of allele distribution in an isolated population, due to random fluctuations in the frequencies of individual alleles of the genes.
Genetic drift is one of the contributing factors of decrease in genetic variation among a population of organisms.

Mosquitoes can carry and transmit many diseases to humans. In the past, the insecticide DDT was heavily used to reduce mosquito populations in order to reduce instances of disease transmission. However, after some time, mosquito populations developed a resistance to DDT, which made the DDT less effective in reducing mosquito populations.
Based on what you’ve learned about natural selection, in 3–5 sentences, describe how mosquitoes may have come to develop this resistance.
Answer:
After mosquitoes in a population are exposed to doses of insecticides that are too weak to kill them, mosquitoes may develop resistance to the active ingredient(s). This makes the use of surveillance-based targeted mosquito control of the utmost importance.Explanation:
