The answer to this one is true
Answer:

Likelihood of their child having short eye lashes - 50% or 1/2
Explanation:
Let the allele for eye lashes be represented by E. Homozygous genotype will be EE (for long eye lashes) or ee (for short eye lashes) while heterozygous genotype will be Ee. Assuming long eye lashes allele E is dominant over shor short eye lashes e:
Heterozygous man marries a short eye lashes woman: Ee x ee
Ee x ee = Ee (long lashes), Ee (long lashes), ee (short lashes) and ee (short lashes.
<em>That is, 50% or 1/2 of the offspring will have long eye lashes while the remaining 50% or 1/2 will have short eye lashes.</em>
Answer: The correct option for the fill in the blank is B) Transcript, ribosome.
mRNA is formed by a template of DNA in the nucleus of eukaryotic cells. The genetic information from DNA is transferred to mRNA in process called Transcription. mRNA is transported outside nucleus and helps in protein synthesis at the site called ribosomes.
mRNA thus carries a transcript of DNA instruction out of the nucleus. It helps in the formation of synthesis at ribososme ( present in the cytoplasm of the cell).
Thus, option B) is the right answer.
The answer is <span>The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
Mentioned organisms are diploid (2n) and they have 2 sets of chromosomes in their somatic cells. However, their gametes (egg cells and sperms) are haploid (n) and have only 1 set of chromosomes.
After fertilization, a haploid egg cell from a mother and a haploid sperm from a father fuse and form diploid zygote:
n + n = 2n
Nevermind if n is odd or even number, 2n will always be even.</span>
<span>This is the phosphorus and carbon cycle. By breaking down dead carbon-containing objects and returning them to the soil, these bacteria are able to allow the nutrients to be re-used by future generations of plants and animals, continuing the cycle.</span>
