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!

On land, nitrogen-fixing bacteria convert nitrogen from the atmosphere into ammonia. Other kinds of bacteria then convert the ammonia into nitrates that plants can use. How does this part of the nitrogen cycle on land compare to the process that occurs in the ocean?
A. Plants convert nitrogen into ammonia, which animals convert to nitrates.
B. Plankton, not bacteria, convert nitrogen into ammonia.
C. Plants convert nitrogen directly into nitrates.
D. Plankton, not bacteria, convert ammonia into nitrates.
Answer:During nitrification, ammonia (NH3) is oxidized and converted to nitrite and then to nitrate. This process is carried out by chemosynthetic bacteria (also known as nitrifying bacteria). That is, the energy released during nitrification is used to synthesize organic matter.
2. Denitrification occurs when bacteria in the soil, called denitrifying bacteria, use nitrates and convert them to nitrogen gas. Denitrification ensures that nitrogen is returned to the atmosphere.
3. Atmospheric nitrogen is fixed primarily with the help of bacteria. These bacteria act by forming nodules in the cortical areas of the roots of these plants, where they remove atmospheric nitrogen and convert it to the ammonia (NH3) used by the plants.
Explanation:
Answer: The correct answer is D. Plankton, not bacteria, convert ammonia into nitrates.
Explanation: Confirmed correct.
9) The table shows the minimum pH that some common freshwater organisms can survive in water.
Which organism would be MOST sensitive to acid rain?
A) bass
B) clams
C frogs
D) mayflies
Answer:
Explanation:
The correct answer is option B- Clams
It is very clear how acid rain is affecting our ecosystem. Plants, animals and other living organisms are effected including their habitat.
When acid rain enters soil, it leaches aluminium from soil particles and mixes it with soil. Aluminium level in water intoxicates the water content which is critical for the survival of water animals.
The critical PH level for clams is 6.
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:

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

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.

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.

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.

I NEED THE ANSWER ASAP WILL MARK BRAINLIEST!!!! Hunting and habitat destruction have led to a decline in the cheetah population, and therefore a decrease in genetic variation within the cheetah population. 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.
