The correct answer is: the mother cell is diploid, but the products of the first division are haploid.
Meiosis is cell division with the purpose to produce the gametes: sperm and eggs. Meiosis is a two-step division process:
• meiosis I- Homologues pairs (chromosome pairs an organism receives from parents, one from mother, one from father) separate during this phase
• meiosis II – Separation of sister chromatids.
Answer:
The correct option is A. Cooler, more dense material sink while warmer, less dense material rises.
Explanation:
Convection can simply be described as the transfer of heat energy among molecules or substances. Convection will occur if molecules of liquid or gas are given rough supply of heat. Hot liquids or gases would have the following properties:
- Their density would be less.
- They would have the ability to rise.
Whereas the cooler molecules will have the following properties:
- Their density would be more than the hot molecules.
- They would have the ability to sink.
As Brandon climbs the mountain, he is getting into thinner and thinner air (air pressure is decreasing). All other things held constant, decreasing air pressure means decreasing temperature. As the air pressure decreases, particles get further apart and lose energy as they move about and collide into one another less and less frequently.
Answer:
Involves two intermediate hosts which are :
Explanation:
The life cycle of Trypanosoma cruzi involves two intermediate hosts: the invertebrate vector (triatomine insects) and the vertebrate host (humans) and has three developmental stages namely, trypomastigotes, amastigotes and epimastigotes
