Answer:
Bull = Pp
Cow A = pp
Cow B = pp
Cow C = Pp
Explanation:
In cows polled (P) is dominant over horned (p) trait.
The bull is polled so it can be PP or Pp. Cow B is horned so it must be pp. Resultant offspring from bull X Cow B is also a horned calf (pp). This calf must have received one p from the bull. So the bull's genotype is Pp.
Cow A is also a horned cow so it must be pp. When bull X Cow A, a polled calf is produced. Since the bull's genotype is Pp and Cow A's genotype is pp, this polled calf will be Pp like the bull.
Cow C is polled like the bull so it can be PP or Pp. However on crossing with the bull (Pp) a horned calf is produced (pp). This calf got one p allele from the bull and p allele from the Cow C. So Cow C's genotype must be Pp.
Hence,
Bull = Pp
Cow A = pp
Cow B = pp
Cow C = Pp
The answers that are meant for the blanks spaces are listed below according to their numbers:
1. Nitrogenous
Nitrogenous wastes refers to metabolic wastes that contain nitrogen; two examples of these are urea and uric acid.
2.Water
3. Acid base
Kidney is an osmoregulatory organ, it participates in homeostasis by regulating the amount of water, electrolytes and the concentration of acid base balance in the body. It does this by means of various mechanisms which ensure that the internal environment of the body is kept constant.
4. Kidney
There are two kidneys in the body, they are responsible for urine production. They do this by filtering the blood and removing wastes, the wastes are then processed into urine and remove from the body.
5. Ureters
6. Peristalsis
7. Urinary bladder
Urine production involves the ureters, urinary bladder and urethra, these three form the urinary tract which act as a plumbing system that drain urine away from the kidneys.
8. Exterior
Urethra is the conducting pipe which leads the urine to the outside of the body for excretion.
9. 20 centimeter
10. Semen
The urethra is a tube like structure, which is approximately 8 inches long in male, this is equivalent to 20 centimeters. It is used for the transportation of urine and semen.
11. 4 centimeter
In female, the urethra is between one to two inches long, which is equivalent to 4 centimeter.
12. Urination or micturition.
The process of passing the urine out of the body through the urethra is called urination.
13. The external urethral sphincter
The urethral sphincter is associated with two muscles which are the internal urethra sphincter which is a smooth muscles that is under involuntary control while the external urethra sphincter is a striated muscle that is under voluntary control.
14. Incontinence.
Incontinence refers to poor bladder control, there are many types of incontinence caused by various factors.
Answer:
The culture of a civilization can be changed by the biological situations that surround a society.
Explanation:
Foe example, in eating habits, if there is a society that leave in a place where there is going to grow plenty of fruits and vegetables like in the Caribbean places, people will be used to eat bananas. At the same time fashion or design behaviors or tendencies will be full of color because is the environment that surrounds the artist. At the same time, some language expressions will be formed by comparing animals of fruits of the environment with comparison in the society for example: "cuando suena el rio es porque lleva piedras" (when the river sounds is because it has some rocks) of course this idea means that when is a rumor, is because there is an explanation for it. But of course the relationship is because people can observe how is the normal behavior of a river.
