Answer:
A. Cell wall and chloroplast
B. Nucleus (the dark grey circle)
Explanation:
The correct genotypes of the parents are ggrr for yellow pods with wrinkled seeds and GgRr for <span>heterozygous for green pods with round seeds.
If the heterozygous individuals for both traits express have green pods and round seeds that tells us that these traits are dominant.
In the gross presented below, you can see that the offspring will have 4 different genotypes, all present in an equal percentage:
</span><span>gGrR 25%
</span><span>gGrr </span>25%
<span>ggrR 25%
</span><span>ggrr 25%</span>
Cellular respiration produces carbon and it’s a long process involved with the mitochondria, pretty much cellular respiration puts carbon into the air from plants.
When photosynthesis is how plants grow, by taking the sun as a energy source instead of consuming other things for energy

Answer:
Sinkholes can occur when<u> excessive water use lowers a water table and weakens the substrate.</u>
Explanation:
There are various causes for sinkholes, but all are related to water and how this can affect the soil. One of the causes of sinkholes is the excessive use of water. Excessive use lowers the volume of water in aquifers. As a consequence, the substrates that are above the aquifer change. They can not support large amounts of weight, leading to a sinkhole and soil with low permeability.
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.
