Answer: The correct answer for the blank is-

B. chloroplasts.

Chloroplast is a specialized membrane bound organelle that is present in photosynthetic organisms such as green plants and algae.

It contains a green colored pigment ( chlorophyll) that absorbs energy from sunlight ( in the presence of carbon dioxide and water) and converts it into chemical energy in the form of ATP and NADPH, which is further utilized in the formation of food ( glucose). This process is called photosynthesis.

Thus, chloroplast is considered as the site for photosynthesis.

Therefore, upper palisade layer of leaves contain more chloroplast to carry out photosynthesis as compared to other  parts of the plant.

Thus, option B) is the right answer.

It is chloroplasts because chloroplasts are the organelles responsible for photosynthesis in plants.

The liver acts to keep blood glucose at a relatively constant level. It takes up glucose from the blood when levels are too high
postnew [5]
Yes, these actions are an example of homeostasis. To fully understand this question you need to know the basic concept of homeostasis. Homeostasis is the body's regulation. What do I mean by that? It's simple, when you have a fever your body's temperature can skyrocket to 100 or more, when you start to sweat or get the chills that's your body's way to cool you down and fight the infection. Another example; when you do any physical activity, you sweat from it depending on the intensity. If you didn't sweat you would probably overheat and that would lead to other complications. Basically when you do exercise you sweat because your body is warm and that's the homeostasis mechanism that helps cool down your body bring it to it's normal temperature. So in end answering your question in more detail by the liver regulating the body by taking glucose in when levels are too high or adding glucose in when levels are too low is an example of homeostasis because the body is regulating itself to come back to it's normal healthy function state.

Answer:

Abiotic factors, such as temperature, water, sunlight amounts, and regional terrain, directly effect biotic factors. Biotic factors are the living components of an ecosystem which include primary producers, consumers, and dexomposers.

Abiotic factors can effect organisms in many ways. Hey can effect primary producers negatively if there is too little sun, water, or nutrients in the soil. However, if there is too much of any one of these, they can still be negatively effected. With primary producers, it’s all about balance.

while consumers do not directly require the above conditions, they do rely on the plants and animals that feed on said plants to survive. If the plants do not have correct nutrients, they will not either. As far as terrain goes, they adapt to better cope with the environment. If they live in an aquatic enviromment for example, they acquire ways to more efficiently move through the water to look for food.

Decomposers rely on the remains of dead plants and animals in order to survive. They feed off of dead matter and the waste gets deposited into the soil. This in turn helps to give the soil its nutrients, and so the cycle continues.

Everything in nature is reliant on each other. This delicate balancing act is both beautiful and so very fragile. If one organism is removed, the entire ecosystem could suffer. This is why it is so critical to protect the environment we share with every other living creature on this earth.

Muscle cells contain , a starch-like carbohydrate that provides energy during intense exercise.
nika2105 [10]

Explanation:

Glycogen is a complex carbohydrate that the body can easily and rapidly convert to energy. Glycogen is stored in the liver and the muscles. Muscles use glycogen for energy during periods of intense exercise. The amount of carbohydrates stored as glycogen can provide almost a day's worth of calories.

Why is the phloem in a leaf important to the roots of a plant?
suter [353]

Answer:

The correct answer is A it transport the food generated by photosynthesis.

Explanation:

Both xylem and phloem are the examples of vascular tissue present in plants.xylem helps in the transport of water from root to different parts of the plants.

    Whereas phloem helps in the transport of photo synthate from mesophyll tissue to sieve element companion cell complex.The transport of photosynthate to different non photo sythetic parts of a plant involves both symplastic and appoplastic pathway.

  Symplastic pathway is a passive process depending on the pressure gradient for the transport of solutes through the plasmodesmata which connect 2 adjacent plant cells.

  Appoplastic pathway is an active transport process occuring against the concentration gradient which does not involve plasmodesmata.
