Algae die quickly, so aerobic decomposers come in to decompose dead algae. In this process, decomposed use all the oxygen in an area, thus making that area oxygen deficient, meaning no organisms can live there
The bald eagle and the black bear are tetrapods, which means that they both have four limbs along with the digits. This shows that they both are the descendants of the four-limbed ancestors. However, the limbs of the bear and the bald eagle have different functions. The forelimbs of both these organisms serves different purpose. Hence, their limbs are homologous organs. The homologous organs are those which have the same ancestry but the functions are different.
Answer:
A reversible reaction is a chemical reaction where the reactants form products and products react together with reactants to give the reactants back. When they yield the same amount, Reversible reactions will reach a chemical equilibrium in which the concentrations of reactants and products will no longer change.
Explanation:
Answer:
Explanation:
A cell as the functional and structural unit of life exhibits numerous concepts of life which include:
1. Growth; A cell is a subject to this as the growth of a cell translates to the growth of the tissue is composed of, the cell is responsible for all biochemical actions in living organisms, this growth is achieved via mitosis.
2. Reproduction: Cells also experience reproduction via meiosis, where a diploid cell divides to produce 2haploid cells an example of this is the spermatozoa.
3. Death: Cells are also subject to death, which can either be programmed (Apoptosis), or due to sickness(Necrosis). This is also found when humans die and become stiff due to rigor mortis which occurs as a result of cell death
Answer:
F-: StrR, his+ and met+
Explanation:
the strain Hfr is a high-frequency strain of recombination that includes the F plasmid (fertility factor). Therefore, the whole genome sequence is able to be passed via Hfr to its receiver, but it needs a long duration of physical contact with the recipient because the recipient gets a gene (long time physical contact is seldom attained) and retains the F strain. Also, genomes from the F-cells are not passed backwards to the HF cells. Therefore, only F strain with tolerance to Streptomycin and capable of synthesizing its amino acids on limited media can thrive in this situation. Which is F-: StrR, his+ and met+ recombining.
