Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

<h3>General characteristics of plants</h3>

Plants are classified as autotrophic organisms, since the large one is capable of photosynthesis. With the exception of plants, some achlor species being observed, therefore, not achlorizing plants.

<h3>Chloroplast</h3>

Chloroplast, a structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.

<h3>It happened in real life</h3>

The newly discovered plant — named Gastrodia kuroshimensis — occurs in the dark understory of forests, where little light penetrates. So instead of using sunlight or photosynthesis to generate nutrients, the plant parasitizes the fungi in the forest soil for its daily dose of nutrition.

With this information we can say that the correct alternative is B. where it states that there are no chloroplasts in the plant cells.

B. There are no chloroplasts in the plant's cells.

These plants that do not photosynthesize do not have the green pigment, what gives the plants their green color is the chlorophyll that is in the chloroplast.

What is the part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chrom

Damm [24]

Answer:

Mitotic phase

Explanation:

Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:

G1 (gap 1 phase)-the cell grows and becomes larger
S phase- replication of DNA, duplication of centrosomes
G2 (gap 2 phase)-proteins and oranelles are made

Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:

prophase-condensation of chromatin into chromosomes, the nuclear envelope breaks down, mitotic spindle formation
metaphase-the chromosmes line up (metaphase plate)
anaphase-the siste chromatides move toward opposite cell poles
telophase-the nuclear envelope forms again, cell division is almost complete
