In sheep, white wool is dominant over spotted wool. If 10 purebred white wool sheep (TT) are crossed
with 10 spotted wool sheep (tt), how many offspring will have spotted wool?
05
O 10
ОО
04

Answers

Answer 1

Answer:

0

Explanation:

This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.

In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.

Match the biochemical action with the appropriate hormone: 1) increase in glucose uptake A) glucagon 2) increase in gluconeogenesis B) insulin 3) increase in cAMP levels (muscle) C) epinephrine 4) decrease in lipolysis 5) decrease in glycolysis 6) increase in ketogenesis

Answers

Answer:

1) B) insulin  

2) A) glucagon  

3) C) epinephrine  

4) B) insulin  

5) A) glucagon  

6) A) glucagon  

Explanation:

High levels of glucose in the blood promote the release of insulin hormone which functions to stimulate uptake and utilization of glucose by cells. Insulin may also act to inhibit lipolysis in adipocytes and stimulates triglyceride storage. Glucagon hormone controls blood sugar (glucose) by stimulating glycogenolysis (conversion of glycogen to glucose), promoting gluconeogenesis (glucose synthesis), and inhibiting glycolysis (glucose breakdown). Moreover, glucagon also can increase ketogenesis (i.e., the production of ketone bodies by breakdown of fatty acids and ketogenic amino acids) when insulin is inhibited. Finally, epinephrine hormone binds to receptors localized on the surface of muscle cells, which stimulate the production of cyclic-AMP (cAMP), a second messenger (i.e., a signaling molecule).

3. Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?

Answers

Answer:brainiest Explanation:

Answer:

See below

Explanation:

Active transport is the movement of materials across a membrane that requires an input of energy from a cell. This is because ions move into and out of cells and because cells contain proteins that do not move across the membrane and are mostly negatively charged, there is also an electrical gradient, a difference of charge, across the plasma membrane. the interior of living cells is electrically negative with respect to the extracellular fluid in which they are bathed.

At the same time, cells have higher concentrations of potassium (K+) and lower concentrations of sodium (Na+) than does the extracellular fluid. In a living cell, the concentration gradient of Na+ tends to drive it into the cell, and the electrical gradient of Na+ (a positive ion) also tends to drive it inward to the negatively-charged interior. The situation is more complex, however, for other elements such as potassium.

To move substances against a concentration or electrochemical gradient, the cell must use energy. This energy is harvested from adenosine triphosphate (ATP) generated through the cell’s metabolism. Active transport mechanisms, collectively called pumps, work against electrochemical gradients. Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements.

A transformer in a neon sign contains 20 truns in the primary coil and 80 truns in the secondary coil. Which is greater- the output voltage or the input voltage?​

Answers

Answer:

The output voltage is greater.

Explanation:

The turns ratio is directly proportional.  Vs=  Vp X (ns/np)

In this neon sign xformer example it is 80/20  or 4

So secondary voltage for 120 volt primary/line voltage = 480 volt secondary volts.

This is practical in a neon sign as it takes more voltage to start the neon gas excitation.

The output voltage is greater.

Calculation of output voltage:

Since A transformer in a neon sign contains 20 turns in the primary coil and 80 turns in the secondary coil.

So here turns ratio should be directly proportional.  Vs=  Vp X (ns/np)

So, In this neon sign former example it is 80/20  or 4

Thus,  secondary voltage for 120 volt primary/line voltage = 480 volt secondary volts.
