Some nonliving components of an ecosystem which is some rocks snow rain hail erosion weathering also temperature,and humidity
Density of the animal population Animal population is the only biotic or living factor. Grazing by herbivores, like sea turtles, will affect seagrass populations. Too many herbivores, not enough segrass.
Answer: The tail gives the sperm cell development. It whips and undulates with the goal that the cell can venture out to the egg. Following sperm statement in the female regenerative plot, initiation of tail development is stifled until the sperm is conveyed to inside a moderately short separation of the egg.
Explanation:
Platinum: Mostly mined around that area.
Answer:
The things that happen during meiosis I are:
- <em>Sister chromatids are condensed.</em>
- <em>Homologs come together.</em>
- <em>Homologs separates from each other.</em>
Explanation:
Meiosis is a process of cell division whose objective is to obtain gametes -cells related to reproduction- that possess half of the chromosome charge (haploids). Meiosis consists of two phases, named I and II.
A summary of the events that occur during meiosis I would be
- Prophase I
Homologous chromosomes pair up and form synapses - which can only happen in this process - forming bivalents, structures made up of two chromosomes and four chromatids. The formation of chiasms -the synaptonemic complex- allows the crossing over or recombination between sister chromatids.
- Metaphase I
Alignment of bivalents on the equatorial plate, with highly condensed chromosomes.
- Anaphase I
Each chromosome, formed by two chromatids, separates and moves to each pole of the cell, a process that implies the disappearance of the chiasms.
- Telophase I
There are two haploid daughter cells, not identical due to recombination, with chromosomes formed by two chromatids.
