Answer:
Enterokinase is produced by the duodenal mucosa. It activates trypsin, a pancreatic proteolytic enzyme, which in turn activates the remainder of the enzymes facilitating protein digestion. The pancreas releases other proteolytic enzymes into the intestine that continue the digestive process.
Explanation:
Answer:
Can result in a new variety of gene combinations in the species
Explanation:
The third option is blatantly untrue- gene mutations are sometimes harmful, usually mundane and do nothing, and sometimes extremely helpful.
The fourth option is also untrue- genetic mutation is completely random.
This leaves us with the first two-
The first option is true, but it's not why genetic mutations are important, it's simply how they are passed on.
The second option is the awnser because gene diversity is extremely important in populations, and 'variety of gene combinations' is just another way to say gene diversity.
Answer:
a. In chlorophyll photosystems, the photons excite electrons that are transferred from donor to acceptor molecules in a process that involves oxidation-reduction reactions
b. As negative controls could be produced targeted mutations in genes encoding for enzymes that are not involved in the growth and in the photosynthetic activity
c. The plants that have many classes of photosynthetic pigments absorb light in different ranges of the visible spectrum, thereby it may confer an adaptive advantage to these plants
Answer:
it's a piece of cake
Explanation:
C. haploid + haploid = diploid
62 -- The roots absorb water for the plant, and also provide it with stability, ie to keep it from falling over.64 -- Structure B is a leaf, and a leaf's main function is to take in sunlight and perform photosynthesis, which makes food for the plant.
