Answer:

See the explanation below.

Explanation:

Mitosis has to do with the division of somatic or vegetative cells. Diploid parent cells divide to give rise to two diploid daughter cells that are genetically identical to the parent cells. Mitotic process is important for for wound healing, growth and development of living organisms.

On the other hand, meiosis is concerned with the division of sex cells. Diploid parent cells divide t give rise to four haploid daughter cells that are genetically different from the parent cells as a result of crossing over and recombination. Meiotic process is important in sexually reproducing organisms. It ensures that the ploidy level of organisms are kept constant from one generation to the other.

In mitosis, the first stage is prophase. The nucleolus disappears and the two centrosomes begin to form the mitotic spindle. The spindle xtends between two opposite poles f the cell. Next is the metaphase. The centromeres of the chromatid pairs align at the center of the miotic spindle. Then anaphase, the centromeres will split that separates the chromatid pair. They are now called chromosomes. The last phase is the telophase. The chromosomes will then form a thread-like chromatin and for ache envelope, a nucleoli appears. The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.

The motion permitted at a joint ranges from ____________ , such as where some skull bones interlock at a suture, to ____________

Elenna [48]

The correct answers are no movement; extensive movement.
You cannot move the joints near your skull - at least now willingly - only a doctor can remove parts of your skull if you are undergoing a brain surgery. Otherwise, there is no movement at all there. However, when it comes to your shoulders, for example, you can move them at will in whichever way you want to.

A bacterial cell that contains an outer membrane and periplasmic space stains pink to red on Gram stain. Which one of the follow

anastassius [24]

Answer:

a. No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition.

Explanation:

Gram stain is the staining method used to differentiate bacterial species into two groups, gram-positive and gram-negative bacteria. Factors that will differentiate gram-positive from gram-negative include the coloration of bacteria, the composition and chemical and physical properties of cell walls. In these tests, bacteria that have an outer membrane and a periplasmic space are considered gram negative and pink in color (sometimes similar to red) due to their cellular composition. For this reason we can state that there is no discrepancy present in the bacteria exposed in the question; Because this bacterium has an outer membrane and a periplasmic space, then it is normal for the bacteria to turn pink due to its cell wall composition.
