What are the ways in which captive breeding helps protect biodiversity? Check all that apply
IgorLugansk [536]

Answer:

Following are the ways captive breeding helps conserve biodiversity:

  1. Captive breeding can increase population numbers
  2. Captive breeding can help remove species from the Endangered Species List
  3. Captive breeding can result in the eventual release of offspring into the wild.

Explanation:

Captive Breeding:

Captive breeding is an ex-situ conservation technique (taking the animal out of its natural habitat to increase population numbers in zoos or sanctuaries). Captive breeding involves selective breeding of endangered species to help produce a sizable population that can later be introduced back into the wild when their habitat improves.

Captive breeding programs include zoos, sanctuaries located away from the animal's original habitat. For example, the Toronto Zoo has operated a captive breeding program for the Blanding's turtle since 2012. The turtles are kept their for 2 years after birth and then released back into the wild.

What would happen if glycosis stopped happening in a cell
Aneli [31]

Answer:

cells lose their ability to maintain their sodium-potassium pumps, and eventually, they die.

Explanation:

If glycolysis is interrupted, these cells lose their ability to maintain their sodium-potassium pumps, and eventually, they die. The last step in glycolysis will not occur if pyruvate kinase, the enzyme that catalyzes the formation of pyruvate, is not available in sufficient quantities

What characteristics of DNA results in cell differentiation in developing embryos?
Elina [12.6K]

Hi!


The correct option is B. Which genes are active.


Embryonic differentiation is a developmental process by which embryonic cells give rise to specialized cells and a diverse range of tissue structures. All of this unique cells essentially rise from a type of cells that are known as pluripotent cells.

But how do these pluripotent embryonic stem cells know which cells to differentiate into? This is where genes come into play. The cell has an inherent signalling ability that determines which gene is to be active and expressed. These specifically activated genes then translate into proteins for which it is specific, giving each cell, tissue and organ its particular identity.


Hope this helps!

During which phase of mitosis do the chromosomes become distinctly visible in the microscope?
mylen [45]

Prophase of mitosis do the chromosomes become distinctly visible in the microscope.

During metaphase, the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell. At this stage, the chromosomes are distinguishable when viewed through a microscope. The first stage of mitosis and of meiosis I and II.

During prophase the chromosomes become visible as distinct structures, the nuclear envelope breaks down, and a spindle forms (Meiotic prophase I is more complex, and includes synapsis of homologous chromosomes and crossing over). During Prophase chromosomes become Clearly visible, nuclear envelope disappears, kinetochores and spindle fibers form.
