Match the steps in the cell cycle in the correct order
Tcecarenko [31]

Answer:

1. Chromosomes line up - metaphase

2. Cell growth - G1

3. Final preparations for division - G2

4. Chromosomes get pulled apart - anaphase

5. DNA replication - S

6. Chromosomes condense - prophase

7. Chromosomes uncoil and nucleus reforms - telophase

8. The cytoplasm and organelles divide, and now there are two identical cells - cytokinesis

Explanation:

There are four primary phases, or stages, in the cell cycle, which is a systematic process. Each stage has a goal that has to be achieved before moving on to the next. G1, S, G2, and mitosis are the stages.
There is growth during the G1 phase. A lot of protein is produced and water is pumped in, increasing the volume of the cell. The DNA is also examined at this time to see whether there has been any damage. The G1 phase precedes the S phase, therefore before going into S phase, the cell must make sure it has enough energy reserves.

The cell duplicates its DNA during the synthesis phase, also known as the S phase. DNA content doubles due to the duplication of all chromosomes. The compact state of DNA is created by proteins, which do not exist in and of themselves. Therefore, in order to ensure that the new DNA is properly packed when DNA is replicated, new packaging proteins must be produced. Histones are the proteins that house DNA. The production of new DNA is closely linked to the production of new histones.

A cell multiplies its organelles during the G2 phase. Right before the cells divide into two distinct cells during mitosis, the G2 phase occurs. There must be distinct functioning organelles in each daughter cell. Organelles like the golgi and endoplasmic reticulum are linked networks of sizable membrane pouches that may change size. Other organelles, including mitochondria and chloroplasts, are separate structures that must separate similarly to how cells do.

The process of physically dividing a cell into two daughter cells is called mitosis. Prophase, metaphase, anaphase, and telophase are its four basic stages. The nuclear membrane deteriorates as the chromosomes thicken during prophase. The center of the cell's chromosomes align during metaphase. One chromosome splits in half during anaphase, sending one half to either side. The telophase is characterized by the pinching together of the cell's centre to form two separate cells.

Sensory receptors convert _____ into _____ by signal transduction.
strojnjashka [21]

Sensory receptors convert stimulus into electrical signals by signal transduction.

<h3>What is sensory receptors?.</h3>

Sensory receptors are found in specialized organs such as the eyes, ears, nose, and mouth, as well as internal organs. Each receptor type transmit stimulus or sensory modality which is interpreted to electrical signal and into a single perceptual frame eventually.

Therefore, Sensory receptors convert stimulus into electrical signals by signal transduction.
