The type of specialized cell whose main function is to communicate between neurons is a interneuron.
Answer:
e. Red segregated from brown in meiosis I, and straight segregated from curled in meiosis I.
Explanation:
A cross between two flies heterozygous for both genes produced an offspring with the phenotypic ratio of 9:3:3:1. This ratio is expected according to Mendel's law of independent assortment, which states that alleles of the same gene assort independently during gamete formation.
Before meiosis starts in flies, a single diploid cell duplicates its DNA, so each chromosome has 2 sister chromatids that contain the same information.
- During meiosis I, <u>the homologous chromosomes separate</u> into two daughter cells. The chromosome number is reduced by half, but each chromosome has two sister chromatids.
- During meiosis II, <u>the sister chromatids separate</u> and each daughter cell from meiosis I divides into two new daughter cells (to get the total of 4 haploid cells).
In a heterozygous fly, each homologous chromosome contains a different allele, and the sister chromatids are copies that carry the same allele. For that reason, both traits were segregated during meiosis I.
<span>The answer is A.
Invasive species are species that thrive unregulated
in an introduced environment/ habitat and
affect the biodiversity of the environment.
They boom unchecked mostly due to lack of a natural predator. Therefore, introducing
a predator will limit their growth. </span>
Answer:
Children born to mothers with dark skin, living far from the equator.
Explanation:
I would say this is the answer but I'm not sure. This is just what I think. I asked my mom about it and she said the same thing I did. I hope this helps.
