When Mendel crossed a plant homozygous for round seeds to another plant homozygous for wrinkled seeds, he found that all the pro
deff fn [24]

Answer:

a. The allele for round seeds is dominant to the allele for wrinkled seeds.

Explanation:

Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.

A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".

In plants, chloroplasts are necessary for A. respiration. B. photosynthesis. C. secretion. D. both respiration AND secretion. E.
Ksivusya [100]

Answer:

B- Photosynthesis

Explanation:

Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.

Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located  in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.

Photosynthesis occurs in two stages:

  1. The light reaction stage
  2. The dark reaction stage

The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.

In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.

Which of the following most likely represents a prototype for the concept indicated in parentheses?
garri49 [273]

Answer:

A golden retriever.

Explanation:

Prototype may be defined as the member among the group that is characterized as more central than the other member of the group. Prototype can be used in the taxonomy as well as in the evolutionary history as well.

The prototype is the main representative member of the group. The golden retriever dog is the most common member among all the members listed in the question. Hence, the golden retriever (dog) is considered as the prototype.

Thus, the correct answer is option (e).
