Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion
Explanation:
Transport proteins generally perform two types of transport: “facilitated diffusion,” where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and “active transport,” where the cell expends energy in order to move a substance against its concentration gradient
Water, sunlight, and carbon dioxide
Answer:
It is expected to obtain 576 individuals with normal wings and body with normal hair, 192 with normal wings and hairy body, 192 with vestigial wings and body with normal hair, and 64 with vestigial wings and hairy body.
Explanation:
Since only the wild-type of the offspring cross each other and since the parents have antagonistic phenotypic characters for each gene, all the progeny produced in the F1 is heterozygous with VgvgHh genotype, where
Vg: Normal wings.
eg: Vestigial wings.
H: Body with normal hair.
h: Hairy body.
Once F1 reproduces with each other, the Mendelian proportions 9/16, 3/16, 3/16, 1/16 expected in the F2 generation are produced.
Since in total there were 1024 individuals in the offspring, this amount is multiplied by the expected proportions, giving rise to the mentioned result.
hey buddy here is your answer
b -that the first occurs in the mitochondria and the second occurs in the chloroplasts
explanation:
Oxidative phosphorylation occurs on the inner mitochondrial membrane and the high energy electrons originate from reduced coenzymes NADH and FADH2 (from the Krebs Cycle, Link Reaction and Glycolysis), whereas non-cyclic photophosphorylation occurs on the thylakoid membrane in the chloroplasts, and the electrons
