Answer:

The correct answer is given below:

Explanation:

1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis.  During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.

2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane

3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.

4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase  

5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase.  During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.

How many dna molecules are present in your diploid cells
Tcecarenko [31]

Answer:

92 molecules

Explanation:

DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.

Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).

Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.

How does photosynthesis contribute to the organism’s energy needs
Molodets [167]

Answer:

Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

What happens during interphase
frutty [35]

Answer:

Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin.
