Answer:changes in environmental conditions

Explanation: The kingdom protista includes algae with chlorophyll and are autotrophic in nutrition.They may be Unicellular or multicelllular.some are colonial and others are filamentuous.some protista undergoes both sexual and asexual reproduction eg chlamydomonas and ulothrix.

In asexual reproduction,the cell divides by mitosis;first in the nucleus and chloroplast and later in the cytoplasm.

sexual reproduction occurs when conditions are quite unfavourable.This is essential because recombination of genes occurs during sexual reproduction ,thus leading to genetic variation.the zygote formed may remain in a dormant state until conditions becomes favourable

Describe what happens by the end of anaphase.
Vsevolod [243]

Answer:

d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.

Explanation:

The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.
