The thylakoid membrane contains a protein called ATP synthase. As hydrogen ions pass through the protein, ADP and a phosphate gr

Elden [556K]

The answer is; electromotive force

As the Krebs cycle/ Citric cycle occurs in the mitochondria matrix, hydrogen protons are produced and get accumulated in the inter-membrane space from the matrix of the organelle. It is this electromotive force that is harnessed by the ATP synthase to produce ATP.

rodikova [14]

Cancerous growths are clonal in origin because of cancer cells originate from a single cell that has accumulated genetic changes during cell division.

The human body contains several billion cells. Cells are the teeny, tiny building blocks of our tissues and organs. Every one of us was once a single cell. That cell divided into two new cells after internal replication.

Cells become abnormal when the DNA, which holds the instructions needed for cells to operate, is damaged. The cells they make after that will not be similar to healthy ones. Along with having a variety of appearances, they might also possess different traits. The medical word for this kind of abnormal cell proliferation in body tissue, including skin, is dysplasia. As long as there aren't many abnormal cells and our immune system controls them, we won't get sick from them.

Sometimes these cells can vanish on their own. Only when these cells continue to change and start to divide erratically, leading to lumps or growths, does one of the more than 200 diseases recognized as cancer become apparent. These kinds of growths are tumors.

The complete question is:

Cancerous growths are clonal in origin because of cancer cells __________.

multiple choice questions.

(A). can invade healthy tissues originating from a single cell that has accumulated genetic changes during cell division

(B) can migrate to other areas of the body and form secondary tumors at the new sites

(C) can form a tumor that is localized only at one site

1. releases bile to break down fat lungs 2. helps break down protein small intestine 3. remove carbon dioxide from the body live

Lunna [17]

Answer:

1. Liver

2. Pancreas

3. Lungs

4. Saliva

5. Small intestine

6. Large intestine

Explanation:

1. Liver is a large, infact the largest, organ found in the digestive system. It has variety of functions ranging from detoxification to digestion. The liver functions in digestion by secreting a substance called BILE which helps in the breakdown of fat in the small intestine.

2. Pancreas is another accessory digestive organ which serves as a endocrine organ which secretes enzymes that aid in the digestion of protein and carbohydrate molecules.

3. Lungs are respiratory organs whose function is key to the respiratory system. They are the organs that serve as a medium of the entry of oxygen and removal of carbon dioxide, a process called GAS EXCHANGE.

4. Saliva is a liquid substance secreted by the salivary gland in the mouth. Saliva contains certain enzymes; most notably is the AMYLASE that breaks down starch into sugar.

5. Small intestine is another organ in the digestive system composed of the ileum, jejenum and duodenum. The small intestine is the organ where the absorption of nutrients into the blood from the digested food takes place.

6. Large intestine is the extension of the small intestine whose function is to absorb extra water from undigested food and pass out the remaining as feaces.

What happens during anaphase II of meiosis? The nuclear membrane begins to form around haploid sets of chromosomes. Homologous c

Kazeer [188]

Answer:

The option that says: Sister chromatids separate from each other and migrate to opposite ends of the cell.

Explanation:

This question wants to test us on a very interesting part in genetics that is Cell Cycle, Mitosis and Meiosis.

In mitosis, the cell divide to produce or generate two daughter cells that has the identical genetic infomation just as the one in the parent cell. After mitosis, we have Cytokinesis.

For meiosis, it is divided into two that is meiosis I and meiosis II. Meiosis I is about the separation of homologous chromosomes pairs while meiosis II is about the separation of chromosome into two chromatids.

In anaphase II of meiosis, "Sister chromatids separate from each other and migrate to opposite ends of the cell" after the division of the centromere.
