The answer would be C, chemical messenger. This signals to other cats that that particular spot belongs to them; it serves as a warning. Hope this helps!

In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fr
juin [17]

Correct option(s):

(b) This muskmelon plant's genotype for the fruit taste gene is ff.

(c) This muskmelon plant is homozygous for the fruit taste gene.

A dominant allele is one that is capable of expressing itself even in the heterozygous condition and overshadows the effect of the recessive allele. It is usually denoted by a capital letter. Recessive allele on the contrary cannot express in presence of a dominant allele and is denoted by a small letter.

In the given case the fruit with a sour taste (phenotype) can have two possible genotypes (FF and Ff). The genotype of sweet taste is ff which is a homozygous condition.  

Note: Your question is incomplete, probably your complete question is “In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fruit taste trait has two alleles. the allele F is for sour fruit, and the allele f is for sweet fruit. a certain muskmelon plant from this group has sweet fruit. this plant has two alleles for sweet fruit. Choose the correct option:

(a)  this muskmelon plant's genotype for the fruit taste trait is sweet fruit.

(b) this muskmelon plant's genotype for the fruit taste gene is ff.

(c) this muskmelon plant is homozygous for the fruit taste gene.”

user100 [1]

Answer;

D. The birds have different mating seasons.

Explanation;

-Different species of birds have different mating or breeding seasons. Evolution has played a role in adjusting the timing of avian(birds) breeding seasons to maximize the number of young produced. The breeding season depends on a number of factors, for example In the temperate, subarctic, and arctic zones, the overriding factor is the availability of food. This varies across all different species of birds, irrespective of other similarities they may have.
