<span>Risks of emphysema, asthma and cancer are associated with the tars and hydrocarbons in inhaled smoke. The tar acts to coat the bronchial sacs, in effect causing the bronchial sacs to be damaged beyond repair and suffocating the smoker over time. The hydrocarbons contain cancer causing chemicals that enter the blood stream and are carried throughout the body.</span>

How do biotic factors rely on abiotic and other biotic factors? PLEASE HELP!!
creativ13 [48]
Biotic Factors depend/rely on abiotic factors because living things (biotic) need nonliving things (abiotic) to survive. Biotic rely on other Biotic factors because they need the food and resources from other living things.

For example, we (biotic factors) need energy from the sun and oxygen/air ,which is abiotic factors, to live and grow. Just like plants (biotic) need the sun's energy (abiotic) to help it grow.
I hope u understand me. Sorry If u don't

You are studying two traits in fruit flies:eye color where there are two colors, brown and redwing shape where there are straigh
Irina18 [472]

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.
