The correct answer is C and D.

C. A cell has half the number of chromosomes in metaphase 2

D. There are twice the number of cells in metaphase 2

The difference between metaphase 1 and metaphase 2 is that in metaphase 2 the chromosomes are arranged on a metaphase plate while in metaphase 1 the pairs of chromosomes are arranged in metaphase plate.

Two centromeres where each homologous chromosome are attached to in metaphase 1. In metaphase the microtubules get attached to spindle whereby on the metaphase plate is where the chromosomes are lined up.

tekilochka [14]

Answer:

can ,synthesize specific proteins

Explanation:

Hormones are chemical signals secreted by animals and plant that are capable of regulating body activities and maintain homeostasis.

They are transported in the circulatory system of the body

The action of hormones can be seen after the hormone has bound to its specific receptor found inside the cell.

For instance, steroid hormone and the thyroid hormones can pass through the plasma membrane to their receptors inside the cells.

When they bind with their receptors, the target cells will synthesize specific proteins that produce the characteristic effect of the hormone.

How are Earth’s organisms and crust interdependent?
sattari [20]
The Lithosphere contains all of the cold, hard, solid rock of the planet's crust, the hot semi-solid rock below the crust, the hot liquid rock near the center of the planet, and the solid iron core. The biosphere is the sphere that contains all of the Earth's living organisms. The organisms and crust interact through events between spheres, such as natural events like floods, shifts in the Earth's crust. Some event as such could create soil erosion resulting in decreased vegetation and increase death of organisms. <span>

An organism is discovered that thrives in both the presence and absence of oxygen. Interestingly, as oxygen is removed from the
melisa1 [442]

Answer:

It is a facultative anaerobic organism.

Explanation:

This organism makes ATP (energy provider molecule) by aerobic respiration in presence of oxygen, but when oxygen is removed it is capable of switching to fermentation (sugar consumption increases and growth rate decreases).

This happens because fermentation is much less effective at producing ATP and therefore there is not enough energy for growth.

This organisms are called facultative anaerobic.

Organisms with this type of metabolism include bacteria like Escherichia coli and Salmonella or yeast like Saccharomyces cerevisiae.
