Answer:

d. Genetic material replicates and is joined at the centromere ----- INTERPHASE

b. Chromosomes line up at the equator and chromatids are attached to spindle fibers---- METAPHASE

e. Centromeres divide and single-stranded chromosomes move to the poles ---- ANAPHASE

c. Nuclear membrane and nucleolus reappear ---- TELOPHASE

a. A cleavage furrow or cell plate forms, separating the nuclei ---- CYTOKINESIS

Explanation:

This question depicts the events that occur in the cell cycle. The cell cycle begins with the preparatory phase called INTERPHASE and stops at the cytoplasm division called CYTOKINESIS. The correct order of the options in this question are:

1. D - The genetic material (DNA) replicates at the Interphase stage, specifically the Synthesis phase. The DNA replication is one of the steps the cell takes during the Interphase to prepare itself for division. The replication of DNA forms a structure called SISTER CHROMATIDS, which are replicated chromosomes held at the Centromere.

2. B - After the Interphase stage, comes the actual division (Mitosis). This option shows what occurs in the Metaphase stage of Mitosis. The spindle microtubules attaches to the kinetochore of each chromosome (sister chromatids) and they become aligned at the equator/middle of the cell.

3. E -- This option shows the occurrences in the Anaphase stage of Mitosis. The aligned chromosomes are separated and pulled apart towards opposite poles of the cell by the spindle fibres. Each pole contains a single strand chromatid of a pair. This is actually the essence of the replication process in Interphase stage.

4. C -- After the division of the nuclear material (chromosomes), a process called KARYOKINESIS, the important structures begin to reform in each pole of the cell during the Telophase stage. Prior to separation of chromosomes at the Anaphase stage, the membrane that bounds the nucleus called NUCLEAR MEMBRANE alongside the nucleolus is degraded in order for the spindle microtubules to assess the chromosomes. These structures form at each pole during Telophase stage.

5. A -- After karyokinesis (division of nuclear material), the cytoplasmic content of the cell needs to separate into two in a process called Cytokinesis. Cytokinesis occurs differently in plant and animal cells. Plant cells forms a cell plate due to their cell wall while Animal cells form a cleavage furrow at the equator of the cell.

Biome1: ________Tropical Savannah____________
IceJOKER [234]
EcosystemTropical Savanna is found between sections of tropical rain forest and deserts.  They have 2 seasons; wet (constant humidity) and dry (long periods of dry spells and drought that may cause fires).

Both savanna buffalo and forest buffalo live close to water. The buffalo are found throughout the northern and southern savanna as well as the lowland rain forest.
<span>How might this population suddenly increase? How might this affect the ecosystem?  If there was an increase in population; grasslands during the wet season will be gone, more predators will flock for an abundance of buffalo.
</span>
<span>What might happen to the ecosystem if this population was removed?  If you remove the buffalo from the savanna ecosystem, it can cause a ripple effect such as populations of small mammal (mouse) will double, which will attract more snakes (venomous), it can cause the flea and tick population to increase, and the increase in tick/fleas can cause the risk of transmission of flea/tick borne pathogens.</span>

Do prokaryotic cells have any of the extra credit organelles? thanks so much!!
konstantin123 [22]
Prokaryotic cells DO NOT have centrioles, cytoskeleton, cilia or vesicles but they DO contain a prokaryotic flagella.

hope this helps!

Do you believe that we need to find alternate, environmentally friendly energy sources?
expeople1 [14]

Answer:yes of course if we don’t the environment will die and undiscovered animals will become extinct and we can’t discover them till it’s too late and those polar bears are on thin ice and it’s not fair to them that they have to suffer for our choices
