Answer:
<h2>D</h2>
Explanation:
Photosynthesis occurs in plants and in some other autotrophs, in which they synthesize their food own-self in the presence of sunlight.
They take CO₂ from environment, water from roots and light form sun. Then they produce carbohydrate and O₂.
Chlorophyll capture sunlight and convert this into chemical energy, through which sugars are produced.
Plants produce O₂ which animals use in their respiration.
In aerobic respiration, the final electron acceptor in the electron transport chain is oxygen. It accepts two electrons and a molecule of water is formed as a by product.
In anaerobic respiration, the final electron acceptor in the electron transport chain is pyruvate. Anaerobic respiration commonly occurs in the muscle tissue of animals as a result of intense activity or exertion. Pyruvate is used as makeshift electron acceptor in place of oxygen and is reduced or converted to lactic acid.
The answer is C) evidence of exoskeletons and endoskeletons
<span>Arthropods and Tetrapod </span> have an endoskeleton and exoskeleton. Endoskeleton is <span>a skeleton found within the interior of the body </span>while exoskeleton is the external skeleton that supports and protects an animal's body like the outer shell that protects them from predators.
Answer:
100%
Explanation:
A pea plant homozygous for the trait of smooth seeds;
let that be = ss
A pea plant that is homozygous for the trait of wrinkled seeds;
let that be = ww
if ss crosses with ww; the F1 produces seeds that are all smooth
i.e ss × ww = (sw, sw, sw, sw)
From the question, we are to find the percentage of the second generation that will produce smooth seeds after self fertilization occurs.
i.e sw, sw, sw, sw × sw, sw, sw, sw
= the result will yield ssww for all F2 progeny
∴ the percentage of plants that will have smooth seeds when the F1 generation is self-fertiized is 100%
