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!
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.

Decomposition of the ozone may lead to an increase in mutations because
Mutations increase due to the decmoposition of the ozone because it can allow the penetration of UV radiations such as UVA, UVB, and UVC to reach Earth. These types of radiations can harm us by causing certain diseases in humans such as skin cancer, eye damage, and of course, mutations.
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.
Therefore, the evolutionary mechanism that most likely has contributed to this decrease in the population’s genetic diversity is genetic drift.

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.
