Answer:
She has two different alleles for eye shape, one from each parent
Explanation:
You always receive 1 allele from each parent, and you're heterozygous, those alleles are different.
Answer:
Ecosystem
Explanation:
An ecosystem is a level of organization referring to the group of living organisms including plants, animals, microbes interacting with one another, and also with the non-living parts of their environment e.g temperature, water.
Based on this explanation, a level of organization that encompasses all th living and non living factors interacting in the pond environment represent an ECOSYSTEM.
Answer:
True.
Explanation:
The lac repressor is a molecule that is part of the regulation of genes to metabolize lactose to some bacteria, including Escherichia coli. Bacteria need to metabolize lactose to provide energy to your body, in which case the lac repressor acts as a lactose detector, preventing the genes responsible for lactose metabolism proteins from being activated unnecessarily, thereby preventing lactose digestion. The lac repressor has the opposite function to the lac operon, which stimulates lactose digestion.
However, for some time, it was unclear whether lac repressor inhibits lac operon transcription by inhibiting RNA polymerase binding to its promoter or allowing transcription to begin, but blocking elongation after the bound repressor site.
It is now recognized that lac repressor paralyzes enzyme production in the absence of lactose, and catabolic activator protein (CAP), which aids in the production of glucose in the medium.
Answer:
The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.
Explanation:
The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.
Hydrogen ions are released in the cells on the shaded side of the stem. As a result, the pH of the cells decreases that in turn activates expansins (an enzyme). This enzyme causes the opposite side of the plant to grow toward the window.
