Answer:

Explanation:

All vombatid species have 2n = 14 chromosomes; the koala has 2n = 16, which G-banding studies suggest is derivable from a wombat-like karyotype by means of a simple centric fission in the equivalent of the submetacentric wombat second autosomal element

changes in blood pressure, heart rate, and blood profile in mares during the last 3 months of gestation and the peripartum perio
Scrat [10]

Warmblood mares that were pregnant (n = 10) had their peripartum alterations in blood pressure, heart rate, complete blood count, plasma electrolyte concentrations, and heart rate variability (HRV) assessed.

<h3>What is Gestation ?</h3>

The time during which an embryo, and eventually a fetus, develops inside viviparous animals is known as the gestational period. Although certain non-mammals also experience it, it is usual for mammals. When mammals are pregnant, they may have one or more gestations concurrently, as in the case of multiple births.

<h3>What is peripartum period ?</h3>

The time just prior to, during, and soon following childbirth.

Everyone agrees that the postpartum period starts when the baby is born. Although the end is less well defined, it is sometimes thought to occur six to eight weeks after delivery because by then the effects of pregnancy on many systems have essentially gone back to their pre-pregnancy states.

The following are the steps for B-cell activation. The steps are in an incorrect order.
Nataly_w [17]

Answer:

4. B cells become activated by interacting with helper T cells.  

1. B cells display antigens in MHC class II receptors on the cell surface.  

2. Antibodies released by plasma cells bind to the antigen so they will be destroyed by other cells of the immune system.

3.B cells rearrange their DNA to create a unique B-cell receptor.  

5. B cells undergo clonal expansion.

6. B cells digest antigens that bind to the antibodies on their surface.

Explanation:

B-cells get activated by interacting with helper T cells when they bind to the antigen to receptors i.e (MHC class II receptors on the cell surface) on the surface of the cell. Series of activities such as release by plasma cells which cause rearrangement of B cells causes the cell to divide and proliferate. The process through which daughter cells arise from a parent cell called clonal expansion.

What is one way that the surrounding ecosystem can affect the glacier mouse ecosystem?
pshichka [43]

Answer:

Hope this helps!!

Explanation:

Glaciers act as reservoirs of water that persist through summer. Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures.
