Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.We breathe oxygen from the air into our lungs, and we breathe out carbon dioxide, which is formed in our body as a waste gas. Breathing is essential to life itself. Oxygen must pass from our lungs into our blood for our tissues and organs to work properly. We require Oxygen to live.

thats easy... like really easy.... like really really easy.
oh well, here it is ✍(◔◡◔)
if there was no plant, all the herbivores would die of hunger,
no herbivores, means no food for carnivores, (AKA) secondary consumers, which would eventually mean they would eat each other causing a mass extinction in almost all secondary consumers

reactants in photosynthesis and the products of cellular respiration?
A
Sugar and water
B
Carbon dioxide and oxygen
с
Sugar and oxygen
D
Carbon dioxide and water
The answer is D) Carbon dioxide and water.
Hope this helps! :)
The pairs of chemicals that are understood to be the chemical reactants in photosynthesis and the products of cellular respiration are Carbon dioxide and water. Thus, the correct option for this question is D.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6CO_2+6H_2O[/tex].With the help of this reaction, it is understood that the reactants of photosynthesis are carbon dioxide and water. While these compounds are the product of cellular respiration along with the derivation of energy in the form of ATP.
Therefore, carbon dioxide and water are the pair of chemicals that are understood to be the chemical reactants in photosynthesis and the products of cellular respiration.

• Commensal
• Competitive
Answer:
1. The clownfish and anemones both benefit
2. The herbivore that feed on producers
3. Ant, grass and snail
4. True
5. Commensal
Explanation:
1. The clownfish and anemones both benefit - the clownfish benefit by gaining protection from predators, the anemones benefit from the prey being attracted
2. The herbivore that feed on producers - biotic factors are living factors. Oxygen, sunlight, and climate are all abiotic (non-living)
3. Ant, grass and snail - biotic factors are living factors. Temperature, pH, and rainfall and humidity are all abiotic (non-living)
4. True - At least one organism benefits. The other organism might also benefit (mutualism), be unaffected (commensalism), or be harmed (parasitism)
5. Commensal - commensalism is when one organism benefits and one organism is not harmed or benefited by the interaction

Where does sugar enter the blood? B. How can you tell where sugar enters the blood? C. Where is sugar removed from the blood? D. How can you tell?
Answer:
Well,
Explanation:
For your first question, the intestines.
B.When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.
C. The capillaries.
D. Glycogen is mainly stored in the liver (where it makes up as much as 10% of liver weight and can be released back into the blood stream) and muscle (where it can be converted back to glucose but only used by the muscle). Therefore, excess glucose is removed from the blood stream and stored. In short terms, when it has the lowest content.
Blood sugar or glucose is the major source of energy found in the body. It is derived from the food and nutrient an organism consumes.
A. The blood sugar enters the intestine, where it gets digested. This absorbed sugar then gets discharged in your blood from where it diffuses in the body as a source of energy.
B. The food in the stomach gets divided into smaller, simple compounds as the carbohydrates split into sugar and starch.
It further gets divided into glucose which is the simplest sugar. The glucose then gets absorbed by the stomach and intestine which later discharges into the blood.
C. The excess glucose gets expelled from the blood capillaries and gets stored in the form of glycogen.
D. The excess glucose in the form of glycogen gets collected in the liver cells and muscles, where they can be transformed back into glucose through the process of glycogenolysis.

Phenotype of offsprings: 1 Red: 2Pink: 1White
Explanation:
This question involves a single gene coding for flower color in four oʼclock plants. The alleles for red flower (R) and white flower (W) exhibit incomplete dominance, hence, results in a third phenotype that is pink (RW).
If two pink flowered four oʼclock plants were crossed i.e. RW × RW, the following gametes will be produced by each parent
RW - R and W
Using these gametes in a punnet square (see attached image), the following genotype and phenotype of offsprings will be produced.

2. Nitrogen, as it is found in the ATMOSPHERE, can be used by plants and
animals.
TRUE OR FALSE?
Answer:
false
Explanation:
Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.
