White blood cells (WBCs) are more resistant to lysis than red blood cells (RBCs). When looking at a sample of blood for WBCs, what could you do to reduce interference from RBCs? Group of answer choices Mix the blood in a hypotonic solution, which will cause the RBCs to lyse. Mix the blood in a hypertonic solution, which will cause the RBCs to lyse. Mix the blood in a salty solution to cause the RBCs to lyse. Mix the blood in an isotonic solution and allow the WBCs to float to the top.

Answers

Answer:

The correct option is this: MIX THE BLOOD IN A HYPOTONIC SOLUTION WHICH WILL CAUSE THE RED BLOOD CELL TO LYSE.

In order to reduce interference from red blood cell, mix the blood sample with a hypotonic solution. Because the red blood cells has more solute concentration, water from the hypotonic solution will enter into its cells and with time the cells will burst since they do not have much resistance against lysis. The bursting of the cells will eliminate the red blood cells and leave you with white blood cell to work with.

How does reproductive isolation cause speciation?
A. It flows interbreeding.
B. It stops adaptive radiation.
C. It reduces gene flow.
D. It prevents divergence.

Answers

Answer:

C. It’s reduces gene flow.

Explanation:

Reproductive isolation cause speciation as it reduces gene flow. Therefore, the correct option is C.

Mechanisms that prevent or restrict the exchange of genetic material (gene flow) between populations are called reproductive isolation. When reproductive isolation occurs, populations become genetically isolated from each other, resulting in different evolutionary paths. This may eventually lead to the speciation or evolution of new species. Reproductive isolation limits the exchange of genetic variation between populations by limiting gene flow. This means that genetic changes, such as mutations or genetic drift, that occur in one population do not affect other populations in the same way.

Therefore, the correct option is C.

that must mean 1 family ruled all of europe

The family pedigree of  Queen Victoria shows a number of hemophilic descendants. Because hemophilia is recessive disorder and Queen Victoria was a carrier. X-linked recessive disease most often occurs in males because Males have only one X chromosome.

XY XX^H

XX^H XX^H XY XX^H XX^H

XY XY XY XY XX^H

Which chromosome will cause the disease?

A single recessive gene on that X chromosome will cause the disease. Females have two X chromosomes so they can act as carriers for the disease.

observe the given relation and fill in the blanks cucumber: tendril citrus: meiosis: reduction division mitosis:​

Answers

Answer:

citrus: thorns

mitosis: equational division

Explanation:

From the relationship:

Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.

Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.

How are meiosis and mitosis similar?

Answers

Answer:

both processes of cell division in which cells reproduce

they share similar steps (prophase, metaphase, anaphase, telephase, cytokinesis) (meiosis has a second division but still follows the same steps)

Answer:

Meiosis II is very similar to mitosis; chromatids are separated into separate nuclei. As in mitosis, it is spindle fibers that “pull” the chromosomes and chromatids apart. The end result of meiosis is four cells, each with one complete set of chromosomes instead of two sets of chromosomes.
