Answer:

A coelom is a hollow, fluid-filled cavity found in many living things, where it acts as a protective cushion for their internal organs. In some animals, such as worms, the coelom acts as a skeleton. The coelom also allows the internal organs to move and grow independently of the outer layer of the body wall.

Answer: Coelom is a fluid filled body cavity found in most living organisms.

Coelom is is found between the intestinal canal and body wall, it is lined with mesoderm epithelium.

The function of Coelom is that it function as a protective cushion for living organisms internal organs and it allow the organs to grow and move freely.

Explanation:

Coelom is a fluid filled body cavity present in the body of living organisms. It is surrond the digestive tracts. It is found between intestinal tracts and body wall. Coelom acts as protective cushion for internal organs and allow their flexibility.

There are three types of Coelom and they are;

Aceolomate(Animals with no Coelom).

Pseudoceolomates( Animals with false Coelom).

Eucoelomates( Animals with true Coelom).

The plant cells contains- cell wall, central vacuole
the animal cell have- cilia cetrosomes
Both plant cells and animal cells contains - cytoplasm and mitochondrion
The main structural differences between plant and animal cells are the additional structures found in pants. The structures include, the cell wall, the chloroplasts and also the vacuoles. The similarity between them is that they both contain plasma membrane, a nucleus, a nucleolus, mitochondria, ribosomes, endoplasmic reticulum, golgi apparatus, peroxisomes and the microtubules.

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

Maurinko [17]

Answer;

As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? A).The density of ice would be greater than the density of liquid water, and ice would not float. B). Ice would form in layers, and liquid water would get trapped in between the layers. Liquid water would have a higher specific heat, making it less likely to undergo vaporization. C).The freezing point of water would decrease, making ice more difficult to form.
