Answer:
<em>Heterozygous purple-flowered parents</em>
Explanation:
<em>A cross involving two heterozygous parents for a dominant trait always segregates in 3:1 phenotypic ratio according to Mendel's law of segregation.</em>
In this case, if purple flower colour is dominant over white flower colour and the trait is represent by P, the heterozygous purple-flowered pea plants will be Pp. If two heterozygous individuals are crossed,
Pp x Pp = PP, Pp, Pp, pp
Since P is a dominant allele, the phenotypic ratio will be 3 purple to 1 white.
<em>Hence, the results are consistent with heterozygous purple-flowered parents.</em>
Answer:
The correct answer is A and D
Explanation:
According to Russell's conception that lies in natural proton gradients. He states that Four billion years ago, alkaline fluids bubbled to produce mildly acidic oceans (As CO2 levels were about a thousand times higher, and it reacts with H2O to form carbonic acid, rendering the oceans mildly acidic). Acidity is just a measure of proton concentration, higher in the oceans than in vent fluids. This difference has given rise to a natural proton gradient across the vent membranes that had the same polarity (outside positive) which is similar to the electrochemical potential as modern cells have. This might be the reason that last universal common ancestors of all the three domains have evolved proton pumps.
The axons of the olfactory sensory neurons project to the olfactory bulb in the brain. This part is found in the forbrain and is responsible for the sense of smell. Inside this bulb are spheres of tissue that are called glomeruli. They are from the ends of branching axons.

Honeybees both directly and indirectly benefit humans. We directly use the honey they produce, and we also depend on them to pollinate crops. Bees also pollinate other plants that provide several indirect benefits to humans. These benefits include reducing carbon dioxide in the atmosphere and providing food for the herbivores on which we depend.
Answer:
B
Explanation:
The folds contain ribosomes attached to the membrane. The more the folds the more the surface area to which more ribosomes can attach. The ribosomes are organelles responsible for the manufacture of protein in cells. Thereafter, the proteins are properly folded by the mediation of chaperones in the lumen of the RER.
