Answer:(1)The urinary system's function is to filter blood and create urine as a waste by-product.

(2) two kidneys we have.

(3)The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances.

(4)Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.

(5)A hollow, muscular, balloon-shaped organ that expands as it fills with urine.

(6)The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum.

(7)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.

2. Which is most likely a result of Earth's rotation?
jeyben [28]

Answer:

C. All parts of Earth experience periods of daylight and darkness.

Explanation:

Not all parts of earth experience the same temperatures. For example, Alaska vs. Florida. Alaska is always freezing cold and Florida is generally always warm.

Not all parts of Earth experience extreme temperature changes either. For example, Florida doesn't experience extreme colds and Alaska doesn't experience extreme warmth.

Not all parts of Earth Experience the same amount of day and night. There are month long periods where Alaska doesn't see the sun, and it is pitch black, and dark. Florida experiences a decent amount of daylight. etc.

I used the same states for example throughout my answer to try to not confuse people. I hope my answer helped!

Answer:

18. E. 0%

19. D. 25%

Explanation:

Question 18:

Let's use "B" to represent the dominant allele of "light blue skin", and

"b" for recessive "light green skin".

Squidward => BB - light blue skin

Squidward's bride => bb - light green skin

When they cross, they will have the following offsprings:

(BB) × (bb) - Parent

(Bb) (Bb) (Bb) (Bb) - Offspring

All the offspring would be light green skin. The dominant allele of light green skin will express itself over the recessive allele.

Therefore, the chances of Squidward and his bride having light green skin is 0%

Question 19:

Squidward's son => Bb - light blue skin

Squidward's son's bride => Bb - light blue skin

(Bb) × (Bb) - parent

(BB) (Bb) (Bb) (bb) - offspring

They will have the following offspring:

BB and Bb - light blue - 75%

bb - light green - 25%

Chance of having offspring with light green skin is 25%
