Ln certain species of plant, one purebred variety has hairy leaves and another pure-
bred variety has smooth leaves. A cross of
the two varieties produces offspring that all
have smooth leaves. Predict the ratio of
phenotypes in the F, generation.

Make a punnett square!

Explanation:

Make one and look at the ratio. That's your answer! It shouldn't be hard as there are only 2 phenotypes. idk what the recessive ones are as you didn't mention it, but you should be able to figure it out with a punnett square really easily. Hope I helped!

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
