Go to the Prenatal Testing page for more details. If one parent has sickle cell trait (HbAS) and the other has sickle cell anaemia (HbSS) there is a one in two(50%) chance that any given child will get sickle cell trait and a one in two chance that any given child will get sickle cell anaemia.
Answer:
Option 1.
Explanation:
r-selected species may be defined as the species that has higher growth rate, shows less parental care and the rate of survival of the off spring is low as compared with k selected species.
Black widow spiders have the ability to produce 1000 offspring. Their chances of survival are extremely low and only few species of black widow spiders survive. Hence, black widow spider is r-selected species.
Thus, the correct answer is option (1).
Answer:
I think you forgot to include a photo but.
The plant will absorb water and sun as the strabbaries slowly develop, once they are finished they will soon be eaten by predadores.
The question is incomplete as it does not have the options which are:
- there was no sulfur compound added to the medium, that could be used as an electron donor.
- no oxygen was added to the medium so the organism died.
- there is some inhibitory chemical that is preventing the growth of the bacterium.
- you were using the wrong type of sunlight as the energy source for the bacterium.
Answer:
There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
In the given question, the bacteria which are found in the pond uses light energy to use carbon dioxide and form the glucose molecule. These bacteria are known as phototrophic bacteria.
The process of photosynthesis requires an electron donor and an electron acceptor to use molecule.
The organism when provided the light and carbon dioxide artificially in a culture, the bacteria were not able to grow. The reason for this could be accounted as that there was no electron donor found in the media like sulfur which could donate the electron during the chain reaction.
Thus, the selected option is correct.
Answer:
bibliography is a list of the books and other sources that are referred to in a scholarly work-such as an essay, term paper, dissertation, or a book. The bibliography comes at the end of the work.
