Answer:
Mosquitoes have thin, long bodies and three pairs of extremely long legs. They have scales along the veins of their wings and long beak-like, sharp sucking mouth parts called a proboscis. These two features distinguish mosquitoes from other flies. Mosquitoes also have feathery or hairy antennae.
The question is incomplete as it does not have the options-
A) Gamma-aminobutyric acid (GABA)
B) Acetylcholine
C) Dopamine
D) Serotonin
Answer:
The correct answer will be option- Dopamine
Explanation:
Parkinson's disease is one of the movement disorders which gets worse with time. The disease is caused due to the degeneration of the neurons in the brain which are responsible for the body movement.
Although many brain areas are affected the most common result is due to the loss of neurons in the substantia nigra in which the neurons produce a neurotransmitter called dopamine which is responsible for the body movements.
Thus, Dopamine is the correct answer.
Answer:
3/16
Explanation:
<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.
Assuming the eye color is represented by E and the wing shape is represented by W. At F2
EeWw x EeWw
E_W_ - 9/16 (dominant for both eye color and wing shape)
E_ww - 3/16 (dominant for eye color and recessive for wing shape)
eeW_ - 3/16 (recessive for eye color and dominant for wing shape)
eeww - 1/16 (recessive for both eye color and wing shape)
<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>
I believe studying the hydrosphere would be most important because we haven't explored a good majority of it yet so we need to explore our waters before we explore space
