Answer: Plant Cell

Explanation: Since I cant see in your question about what structure is about I have found that it might be the plant structure and I hope that this would help. I will also post you a picture of it.

A is Vacuole  

B is Chloroplast  

C is Cell membrane

D is Golgi bodies

E is Smooth and rough endoplasmic reticulum  

F is Cell wall

This structure is a plant cell structure and it has a cell wall and plasma membrane.

Also, it has vacuoles in the center that are taking much space since they are huge.

Since it is a plant cell it has a chlorophyll and with it organelles and both of them are called chloroplasts.

Chlorophyll is giving the plant cell a green color. This kind of cell is a basic and the most important for the Plantae kingdom organisms.

At your lab station, you put 30 mL of hydrogen peroxide into three separate beakers and add 2 grams of ground up liver to each o
stepan [7]

Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.

The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.

At room temperature, a moderate number of oxygen bubbles were observed.  The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.

Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.

More on the effects of temperature on catalase activities can be found here: brainly.com/question/18650715

Paul [167]

Answer:

Heart disease is prevalent in the United States because... well, we consume a lot of sodium and fat. If you look at the stats, we are the third country with the most obese residents, with a whopping percentage of 36.20% people in the US tipping the scales. Also, people smoke a lot. Not just adults, but teenagers. Because of this, youngsters tend to also get heart disease too, despite the small age. According to cdc.gov, a family history of heart disease increases the rates, especially if one of your relatives got it under the age of 50. Due to the smoking rates at a young age, those diseases tend to transfer and increase the rates of the future US citizens.

Heart disease can affect a lot of organs, but listing them would be a pain. Here are the highlights: The heart and the lungs are intimately connected. This means that having heart disease may lead to having trouble breathing. You may have chest pains, and particularly in woman, it may affect the digestive system and cause stomach pain when eating.
