decaying organisms, which died due to the__________.

The bacteria use the oxygen for__________.

Sergeu [11.5K]

Answer:

C. Damaged vascular tissue could cause the fruit to not completely develop or even develop at all.

Explanation:

If the vascular tissues such as xylem and phloem are damaged, the fruit does not completely develop because the food that is produced in the leaves does not reach to the seed. The xylem helps in the transportation of water from the soil that is necessary for making of food during the process of photosynthesis so damaged xylem will not produced food and no food will be transported from leaves to seeds and if some food is produced by the leaves the phloem does not transport it to the seeds.

In mice, the allele for black fur is dominant to the allele for brown fur. a male homozygous black mouse is crossed with a femal
Darina [25.2K]
B- black allele;
b- brown allele;

The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb

The F1 generation will be all black heterozygote: Bb
The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb
In this cross it would result in:
 1/4 of the plants being black homozygote-BB 25%
2/4 of the plants being black heterozygote- Bb- 50%
1/4 of the plants being  brown homozygote- bb- 25%
answer: 25%+25%=50%  are homozygotes
