One of the challenges that scientists face when classifying a new fossil is that any tiny detail is all that separates one species from another. Further exploration is required to identify another set of characteristics that may help in deciding which organism belongs or create a new class.
Answer: Hello :)
Explanation: Speciation and the three selections (directional, disruptive, and stabilizing) all affect biodiversity. ... The affects of this are the evolution of a new species, genetic variation, and an increase in biodiversity. Stabilizing selection is a process by which average individuals in a population are favored.
1. False. They are similar, though.
meiosis- A kind of cell division involving having the chromosome number. It is responsible for genetic recombination.
Gametogenesis- It's the process when gametes or germ cells are produced in an organism. They undergo meiosis to form gametes.
2. Spermatogenesis- happens in the testes of males. 4 gametes are produced. Spermatogenesis involves a metamorphosis stage called spermiogenesis. Spermatogenesis produces small, motile spermatozoa
Oogenesis- takes place in the ovary in a female. 1 gamete produced. in oogenesis there is no metamorphosis stage. In oogenesis the ovum is spherical, and isn't motile and is bigger with more food reserves and cytoplasm.
3. Because The one egg cell that results from meiosis contains most of the cytoplasm, nutrients, and organelles.
A T cell, or T lymphocyte, is a type of lymphocyte a type of white blood cell that plays a central role in cell-mediated immunity.
