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.
Answer: After several days, a large bubble of gas collected in the upside-down beaker contains OXYGEN.
Explanation:
Plants are known to be be autotrophic (producers) through the use of inorganic substance such as water, carbondioxide and light energy from sunlight in a process known as photosynthesis.
An experiment was carried out by Latecia for investigation of the gas production of a water plant. It's therefore expected that OXYGEN gas which is the by-product given off during photosynthesis in green plants would be collected from the upside down beaker as gas bubbles.
Answer:
a.Most bacteria and fungi are harmless and may be beneficial to other living things.
Explanation:
Bacteria and Fungi are two distinct organisms that belong to different class of organisms. Fungi are eukaryotic while bacteria are prokaryotic. Although they both exist in different life forms such as being parasitic, saprophytic etc. most bacteria and fungi species are harmless and may even be beneficial to other living things.
Bacteria and Fungi are beneficial to other organisms in the sense that they form mutualistic relationships with other living organisms. For example, certain species of bacteria helps to fix nitrogen in the root nodules of leguminous plants, while fungi forms a mutualistic relationship with algae called LICHEN where they benefit one another in a way or the other.
The answer would be osmosis
