<h2>Regulate of Environmental</h2>

Explanation:

The motivator based administrative methodology progresses in the direction of forestalling ecological issues by giving promptings to urge contaminating substances to diminish contamination.
An advantage of the motivator based methodology is that it energizes the production of imaginative and financially savvy techniques for contamination control.
Administrative methodologies require government offices to limit or direct the exercises of controlled gatherings utilizing terms and conditions inside statutory and administrative instruments, working grants, licenses, endorsements or codes of training.
Command and control causes administrators to benefit as much as possible from whatever hardware they have - individuals, data, material, and, regularly generally significant of all, time.
Particles have assisted with securing nature, they have three weaknesses.

They give no motivating force to going past the cutoff points they set.
They offer restricted adaptability on where and how to lessen contamination.
They regularly have politically-spurred escape clauses.

Meiosis Foldable Activity 515.2

Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

homologs pair off into bivalents
At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I forming bivalents; tetrads are formed.
Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

Why must each chromosome make a copy of itself before the m phase begins

klio [65]

The each chromosome makes the copy of itself before the M Phase in mitosis because the resultant daughter cell the chromosomes is genetically identical.

Explanation:

The parent cell in the chromosomes make the copy before mitosis. The copy is occurred during the S phase of inter phase. During the mitotic M phase, the cell divides the copied DNA and cytoplasm to make two new cells.

M phase involves two distinct related processes which is mitosis and cytokineses ;the cell growth steps into the new stage and cellular energy is developed on the division in the phase .
