Explain how environmental agents such as chemicals and radiation cause cancer.

Biology

Paul [167]3 years ago
4 0

Chemical (mutagens) usually either mimic the structure of nucleotides and are inserted in DNA or either cause chemical changes  (such as alkylation) in nucleotides hence causing mismatching during replication. Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an increased likelihood of mutations during the repair of the DNA by cell mechanisms.

Do you think monogamy and polygamy are reproductive strategies? In terms of species survival, what are the advantages and disadv
sdas [7]

Answer:

Indeed, both monogamy and polygamy are reproductive strategies adopted by the different species of the animal world.

Explanation:

Polygamy implies the adoption of a unique and stable partner by an individual, with which in principle it will reproduce. Different species, including humans or penguins, in addition to maintaining the same pair for reproductive purposes, generate bonds of coexistence.

Other species (in fact, most animal species) are not guided by this type of relationship, but fulfill their reproductive functions in a random way, that is, with several individuals of the same species in a random way, which is called polygamy. In this case, there is a constant change in the reproductive couple, which responds to multiple factors such as for example a gender disproportion within the species (for example, many females and few males would make those few males have to comply reproductive functions with several females during the mating period), or due to the non-sedentary nature of life of these species.

A biology teacher wants students to remember the various components of a cell (nucleus, cytoplasm, cell membrane). Considering w
Ann [662]

Answer:

Considering what research tells us about encoding and retrieval, the teacher would be well advised to help students encode information about the cell <em>in both visual and verbal forms.</em>

Explanation:

Psychological studies have shown that images are able to generate better memories in a person. Anything which is learned through images will be remembered  by the human brain for a longer period of time.Also, anything which is learned from a language which the brain interprets is known to generate memories. Hence, both visual and verbal forms of learning would help the students to learn components of a cell.
