Answer:
In my experience, the ways to optimize a laboratory are as follow:
1-Have optimized the space for the laboratory equipment
2-The Laminar Flow Hood need to be close to the outdoor
3-Need to have drawers under the lab counter
4-Need to have many labeled places to put minor equipment
5-It is necessary to train new researchers before they use the reactives and the lab equipment
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
Explanation:
Meiosis consist of two successive divisions while mitosis has one cell division. Mitosis occurs in the general body cells resulting in growth while meiosis is the process that occurs during the formation of sex cells. Mitosis results in diploid two daughter cells that are identical to one another and to the parent. Meiosis results in haploid daughter cells each containing half the number of chromosomes as compared to the parent cell.
Answer:
a I guess??? not too sure
Answer:
Although elephants and hyraxes at first don't seem to have many similarities, a closer look has led many scientists to believe that these animals are evolutionarily closely related.
Elephants and Hyraxes share many reproductive characteristics that indicate a common ancestor: The location of the testicules in these animals diverges from most mammalian species, remaining inside the retroperitoneal abdomen. Females have similar placental origins and long gestation periods and the location of the mammary glands in both orders (above the front legs) is a unique feature among non-primate mammals. Hyraxes' tusks develop from incisor teeth, similar to elephants, and in both cases nails develop into flattened, hoof-like structures.
Molecular evidence has also been used to confirm the hypothesis of evolutionary relatedness between the two orders, as similarities in some gene sequences in mitochondrial DNA and other molecular components. Both animals have some physiological similarities and cognitive characteristics (such as the presence of a powerful long-term memory) that support the possibility of evolutionary proximity.
The fossil record indicates that in the Eocene period hyraxes were dominant herbivores in Africa, with several species, reaching much larger sizes than today and occupying different ecological niches, indicating that elephants and hyraxes may have been very similar millions of years ago.
