Answer:
Gravitropism is the movement or growth of a plant in response to gravity. ... Plant shoots demonstrate negative gravitropism since they grow in the opposite direction of gravity. Gravity is sensed by specialized cells called statocytes, which have statoliths that sink inside the cell.
Explanation:
Answer:
Shape of active site changes that's why
Enzymes are affected by temperature. So, as temperature increases, enzymes activities also increases, till optimum temperature is reached. If it goes above the optimum temp, the enzymes becomes denatured or can't function anymore due to change in its active site.
The feature hair type is coded by a diallelic gene and expresses incomplete dominance. The cross of two wavy haired individuals will produce 25% curly-haired children, 50% wavy-haired and 25% straight-haired children.
<h3>
What is a Punnett square?</h3>
The Punnett square is a cross representation that shows all possible combinations between the parental gametes.
It shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
Let us say that we are analyzing the feature hair type.
Hair type is coded by a diallelic gene that expresses incomplete dominance.
- The dominant allele C codes for curly
- The recessive allele c codes for straight hair
- The combination of both alleles in heter0zyg0us state codes for wavy hair.
Let us say that both parents have wavy hair.
Cross:
Parentals) Cc x Cc
Gametes) C c C c
Punnett square) C c

F1)
<u>Genotype</u>:
1/4 = 25% of the progeny will be h0mzyg0us dominant, CC.
2/4 = 1/2 = 50% of the progeny will be heter0zyg0us, Cc.
1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive, cc.
<u>Phenotype</u>
1/4 = 25% of the progeny will have curly hair (CC).
2/4 = 1/2 = 50% of the progeny will have wavy hair (Cc).
1/4 = 25% of the progeny is expected to have straight hair (cc).
