Answer:

The correct answer is - warms, moist air rises.

Explanation:

When moist warm air rises and meets with the surface of cool air the more dense air that is cold air end up below the warm moist air in the troposphere it condenses as it rises.

The condensation of the warm, moist water leads to the formation of cloud formation. This cloud gets bigger and bigger until it precipitates and rain fall occurs.

Summarize how the functions of organelles in animal cells and plant cells are the same and different.
Alex_Xolod [135]
<span>Plant and animal cells have different structures. One structural difference of plant cells and animal cells is the presence of the plant cell’s </span>cell wall,<span> specialized plastids and a large central vacuole which are not found within animal cells.

Another difference is the garbage disposal of each cell. Centrosomes and lysosomes are found in animal cells but both do not exist within plant cells. The animal cell’s garbage disposal takes place in the lysosome while garbage disposal of plant cells takes place in the vacuole.</span>

Starting from the mouth, describe the pathway that takes through the digestive system
bonufazy [111]
Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.

Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.

Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.

Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.

Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.

Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.

Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.

A gene has 2 alleles, R &amp; B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls loo
irakobra [83]

Answer:

5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)

6.) Frequency of R: 0.5

7.)Frequency of R: 0.5

8.)Frequency of R: 0.375

Explanation:

5.) If R and B code for the different forms of the same protein then they are only a few possible out comes

6.) First calculate the total alleles in population

allele R= 40

Allele B=40

total allele = R+B= 40+40

=80

Now to find allele R frequency is:

(Total R alleles) / (Total allele in pop)

40/80=

0.5

7.)Calculate the total alleles

Alleles from for R

RR= 10

R=10x 2= 20

Multiply the value by 2 because there are 2 R alleles present in

RB=20

R=20

Number doesn't change there is only 1 R allele

Total R=20+20

=40

Alleles For B

BB=10

B=10×2

=20

Same thing here, two B alleles together so multiple by 2

RB=20

B=20

Total B= 20+20

=40

Total alleles in pop add

40+40

=80

Frequency of R

Total of R/Total Alleles

=40/80

=0.5

8.)Repeat the same thing in 7 but use different numbers

RR=10

R=10x2

=20

RB=10

R=10

Total R= 20+10

=30
