Answer:

Please see below.

Explanation:

Some alleles have multiple effects in the phenotype. The allele that causes beaks to be deeper likely also causes the beaks to be wider, so both traits are associated and will vary together. Therefore the population will always show a deeper and wider beak or a shorter and narrower beak depending on the environmental cues available that select for either state.

Answer:

There are two ways plants can achieve this. First, they can minimize the resistance to diffusion of CO2 through the stomata (i.e., have lots of large, open stomata). Second, they can maximize the biochemical rate of fixation (i.e., have high concentrations of photosynthetic enzymes).

Which of the following pathways are upregulated by AMPK?
Angelina_Jolie [31]

Answer:

d. Glycolysis

Explanation:

AMPK or AMP kinases are enzymes that play role in regulation of cellular energy needs and is found actively in regions which require constant energy like brain , liver . It is activated when there is an energy crisis in the cell.

It serves to conserve energy. It enhance uptake of glucose and fatty acids for energy , it reduces pathways that require energy.

AMPK is a threonine serine kinase and not tyrosine kinase.

Hence ,

AMPK stimulates glucolysis by activating phosphorylation of 6-phospho-fructo-2-kinase and activating phosphorylation of glycogen phosphorylase .
