Answer:
Meiosis is the process of development of gamates in sexually reproducing organisms. Both males and females use meiosis to produce their gametes. In females the process of meiosis is called oogenesis as it produces oocytes which further develops into ova (eggs) and in males spermatogenesis takes place to produce sperms. Meiosis takes place in the germ cells of the organism. Meiosis is also known as reduction division as a diploid cell reduce to develop 4 haploid daughter cells. Prophase I is the initial phase of meiosis. This phase has six substages, therefore it requires more time to complete especially in oogenesis. During prophase I homologous chromosomes pair exchange their DNA this process results in chromosomal crossover. The new combination of DNA in the cross over chromosomes will be a source for genetic variations with production of new combination of allele. In metaphase I homologous pair of chromosome move together along a metaphase plate , microtubules emerge from the spindle and attach at the kinetochores near the centromere of each chromosomes. Microtubule from one side of the spindle attach to one of the chromosome in the homologous pair and that of other side attaches with other chromosome of each pair. Because of microtubules chromosome pair align at the metaphase plate (equator of the cell). The random alignment of chromosome pair at the equator plate will result in different proportion of transfer of genes from maternal and paternal chromosomes. This is the law of independent assortment, hence this will result in genetic diversity in the daughter cells.
Answer:
A. They could contaminate surface and ground water sources.
Explanation:
- Landfills are biodegradable waste sites that contain harmful gases and thus are kept at the periphery of the city. They include greenhouse gases and contribute to global warming.
- These landfills are hazardous places as they contain pollutants that pollute the environment and water, land, and soil.
Answer: The two species were Rhesus monkey and Human <span>
Hemoglobin protein is the iron containing protein found in
the red blood cells which function by transporting oxygen through the blood
stream from from the lungs to the tissues and it is important for survival. However,
the two species that
have similar amino acids in the hemoglobin protein were Rhesus monkey and Human
because they were not far from others.</span>
Answer:
The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient . Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
