Answer:
Humans would lose a large part of their diet. Insects would would increase a lot. We would lose all products produced from bird parts.
Explanation:
Because the lung has two bronchi, it can still function if one bronchus is blocked by a foreign object. No gas exchange will happen to the affected side, and the other lung will compensate for the loss of air. The blocked portion though can become inflamed and can lead to infection and damage.
(a) The alleles of white feathers and that of single-head combs are dominant while that of the dark feathers and small combs are recessive.
(b) 1/16 or 6.25%
<h3>Dihybrid crossing</h3>
Since all the offspring resemble their mother, it means the alleles that make up the traits of the mother are dominant over that of the father.
Assuming that:
Feathers color = F/f
Comb type = C/c
Genotype of mother = FFCC
Genotype of father = ffcc
FFCC x ffcc
FfCc
Crossing: FfCc x FfCc
Progeny
F_C_ = 9/16
ffC_ = 3/16
F_cc = 3/16
ffcc = 1/16

Fault-block mountains are formed in areas of rifting. Rifting is where the crust spreads. Where rifting occurs, you will have a fault line, on one side of the fault, the crust will sink and other the other side, it will rise.
The sinking side is called a graben and the rising side is called a horst. Horsts usually form the mountain ranges called fault-block ranges
examples include the Grand Tetons
Mount Holyoke Range of Massachusetts
many of the ranges in the basin and range region in the American Southwest
Endometrium layer of the uterus undergoes cyclic changes and is shed during the menstrual cycle.
<h3>What is endometrium?</h3>
- The lining of the uterus is called endometrium.
- Throughout a person's fertile years, it is one of the few organs in the human body that changes in size on a monthly basis.
- The body gets ready for the endometrium to house an embryo each month as part of the menstrual cycle.
- The most frequent cause of endometrial hyperplasia is an excess of estrogen without progesterone.
- Progesterone is not produced and the lining is not removed if ovulation does not take place.
- In reaction to estrogen, the endometrium might continue to expand.
- It's possible for the lining's cells to group together and develop abnormalities.
