Answer:
Diploid Genotype - Genotype of Gametes
RR - R
rr - r
Rr - R, r
Explanation:
According to Gregor Mendel in his law of Segregation, he stated that the alleles of a gene gets separated into gametes during gamete formation (meiosis). This occurs in such a way that only one allele of the two possible alleles that make up the genotype of a diploid organism is found in the gamete.
Meiosis is a cell division that reduces the chromosomal number of the daughter cells. Hence, a diploid organism (2n) will undergo meiosis to produce haploid (n) daughter cells (gametes). An organism with a diploid genotype RR will produce gametes which have only genotype R. The same applies to organism with genotype rr. Only gametes with genotype, r, will be produced.
However, in a heterozygous genotype like Rr, the different alleles will separate into gametes in an equal proportion i.e. gametes with genotypes R and r will be produced in a ratio 1:1.
Answer:
Urban explosion would be a concern in regard to environmental science because of two major things.
Explanation:
There is the amount of space the growing cities will take up that takes away from the environment, and the pollutants the cities produce.

<span>Allergies are caused by D. reactions to antigens. Antigens are some kinds of toxins that can cause a reaction in your body, and that reaction is usually in the form of an allergy. The other options do not really have much to do with allergies, but rather other forms of diseases and illnesses. </span>
Specialized cells that filter out food particles, such as bacteria; characteristic of sponges. Animal that obtains organic matter for nutrition by filtering particles out of water. Opening through which water flows out of a sponge; excurrent pore.
Answer:
The correct answer will be option-true.
Explanation:
Photosynthesis reaction proceeds in two phases: light-dependent and light-independent reaction.
During light-dependent reaction which takes place in thylakoid membrane intermediates like ATP and NADPH are produced through electron transport chain.
These intermediates are directly utilized in the light-independent reaction which performs cyclic reactions known as the Calvin cycle. Calvin cycle produces glucose molecules using ATP and NADPH in the reactions.
Thus, option-true is the correct answer.
