The speed of the cross country runner is equal to 4 km/min.
Given the following data:
Distance = 8 km.Time = 2 minutes.To determine the speed of the cross country runner:
Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).
Mathematically, speed is given by the formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Speed = \frac{8}{2}[/tex]
Speed = 4 km/min.

briefly describe how you can tell when you are repaying the oxygen deficit
You are repaying the oxygen deficit when you have elaborated breath after a long workout.
We can define oxygen deficit as the difference between the oxygen that our body needs during a workout and the one that it gets, which is not enough.
We can tell when our body is repaying the oxygen deficit when our breath is elaborated. What our body is trying to do is to expel carbon dioxide and take as much oxygen as it needs with quick and short breaths.
In conclusion, elaborated breath is a sign that we are repaying the oxygen deficit.

Why is air temperature above land warmer than the air temperature above water in the same location during the summer?
Answer:
Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water
Explanation:
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

explain the effect of germination on pea seed respiration
Answer:
"The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration."

a group of unicellular organisms that live together but have on relationship to one another
The group of unicellular organisms that live together but have no relation to one another is called colonial organisms.
What are colonial organisms?The organization of cells leads to their efficiency. The organization of cells leads to the formation of tissues and organs which leads to the efficient functioning of an organism.
The organization of cells is not only seen in the multicellular level of organization. It starts from the organization of molecules to form structures like proteins and nucleic acid.
Unicellular organisms are able to live and survive independently and perform all life processes necessary for their own survival. But, bacteria are often found to live together in colonies.
A colony is a group of individual organisms that live close to each other. They live together because they are stronger in a colony. A colony of bacteria can protect themselves, acquire their nutrition or attack a host in a better way.
Therefore, a group of organisms who live close to each other and have no relationship is called colonial organisms.

1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. Type your answer here:
Explanation:
The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.
why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?
A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.
Answer:
i think the answer should be b.
the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!
btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

How could the changes made to the amino acid sequence influence phenotype changes?
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Protein structure ordersThe sequence of a protein is determined by the DNA of the gene that encodes that protein (or that encodes a portion of the protein, for multi-subunit proteins).
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Even changing just one amino acid in the protein sequence can affect the protein's overall structure and function. For example, a single amino acid change is associated with sickle cell anemia, an inherited disease that affects red blood cells.
