Rose pollen is large and sticky in comparison to grass pollen as it has to stick to insects to cross pollenate! Grass pollen is produced in larger quantitys and is smaller and lighter than rose pollen because grass pollen is dispersed by wind!
Answer:
Chromosomes will not align at the equator of the cell, and subsequently will not separate to opposite poles.
Explanation:
Mitosis is a cellular division that results in daughter cells with identical copies of the genetic material as the parent cell. Mitosis is characterized by different stages viz: Prophase, Metaphase, Anaphase, and Telophase. The centromere is a very important part of the cell during division as it produces microtubules that grows out and bind to the kinetochore of each chromosome, hence, aligning them at the CELL PLATE (cell equator) and subsequently pulls them apart to opposite poles. This alignment and pulling apart occurs during METAPHASE and ANAPHASE respectively.
Mutation is any change that occurs in the nuceleotide sequence of the genetic material (DNA). If a change/mutation occurs leading to a defective or non-functional centromere, the centromere will no longer be able to produce microtubules that will bind to the kinetochores of each chromosome. Therefore, the chromosomes will be unable to align at the equator/middle of the cell and most importantly, inability to separate to opposite poles, which is the main point of Mitosis.
The correct option is D.
Catabolic metabolism is the process by which large particles of substances are broken down in the body to form smaller particles. Cellular respiration is an example of catabolic process. The process breaks down food particles into smaller particles which are easily absorb by the body and in the process energy is also released. The first stage of the process take place in the cytoplasm while the second stage occur in the mitochondria.
<span>Essentially, karyotypes are the number and visual appearance of the chromosomes found in an organism. Pedigrees are t</span>he genetic makeup of a person's ancestors; usually, a chart which follows a single trait as it is passed from generation to generation.
In pedigrees, we can observe carriers for a particular disease through symbols and shades throughout generations. In pedigrees, we can observe the succession of the diseases throughout generations. We can also deduce the genotype and phenotype of the offspring based on pedigrees with family histories of the disease. T<span>his can only be observed in karyotypes because we are able to visualize the chromosomes per person.</span>
