Answer:
Anthocyanin is not produced in the plant cells
Explanation:
Anthocyanin is not produced in plant cells with the genotype mm.
As you can see from the question above, anthocyanin is responsible for the purple color of the flowers. Anthocyanin is encoded by the M gene, which is a dominant gene. Because it is a dominant gene, we know that it will be expressed in plants with the Mm and MM genotype, but will not be encoded by plants with the mm genotype. With this we can conclude that plants that have the mm genotype do not have purple color, because anthocyanin is not produced in the plant cells of these plants, since they do not have the M gene.
Yes they can to create new tissues
Answer:
The correct answer is - they both have highly folded membranes.
Explanation:
Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.
As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
Answer:
Carbohydrates
Explanation:
The result of photosynthesis is the production of sugar molecules knowns as. carbohydrates. carbohydrates are. energy rich molecules which organisms use to carry out daily activities. as organisms consume food and use energy from carbohydrates, the energy travels from. one organism to another.
Lets understand the given passage.
An ecologist <u>observes that the diet of a bird species consists primarily of large grass seeds</u> (as opposed to smaller grass seeds or the seeds of other herbaceous plants found in the area).
<u>He hypothesizes that the birds are choosing the larger seeds because they have a higher concentrations of nitrogen than do other types of seeds at the site</u><u>.</u>
<u>To test the hypothesis, the ecologist compares the large grass seeds with the other types of seeds, and the results clearly show that the large grass seeds do indeed have a much higher concentration of nitrogen.</u>
No, he cannot conclude that the birds select the larger grass seeds because of their higher concentrations of nitrogen. The hypothesis testing done by the ecologist is incomplete as he failed to set up a control in the experiment. The control would have been the birds feeding on large seeds that lack or are low on nitrogen content. This will establish a relation between the bird's diet and the size of the seeds and the nitrogen content of the seeds. It could be true that birds do not care about the nitrogen content but simply prefer larger seed sizes.
Another problem associated with his field experiment is the failure in noting the beak sizes of the birds. The beak size and shape enable a bird to break and eat seeds. Larger beaks fail at breaking open smaller seeds. This observation would add bird beak size as another variable of the experiment.
