Answer:
The correct answers are: B) Catalase works best at human body temperature, C) Normal human body temperature is 98.6°F, which equals 37°C.
Explanation:
Catalase is an enzyme found in our bodies that has the important task of <u>breaking down hydrogen peroxide</u>, a molecule that is very toxic. For catalase to work at its optimus speed, it need the body to have a temperature of 37° celsius -98.6°F-, which is what we normally call <em>human body temperature</em>. If the temperature rises or falls below body temperature, catalase will still work but at a much slower rate, until it stops working completely.
Not all enzymes work best at human body temperature, some enzymes reach their optimus state at higher or lower temperatures; but it is important to remember that enzymes are proteins, and proteins denaturalize when the temperature becomes to high, making them lose their shape and function.
Answer:
negative, inhibition
Explanation:
The experiment in the illustration shows that early succession plants have a <u>negative </u>effect on the late succession plants, and the observation is most consistent with the <u>inhibition</u> model of succession.
<em>That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.</em>
There are 3 different models of succession. These include;
- Facilitation model in which colonists modify the environment to favor the growth of later successional species.
- Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.
- Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.
Answer:
A. 1' ... 5'
Explanation:
The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.
Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.
B) Endocrine disruptors mimic hormones that regulate critical biological processes
The answer is alleles detached from one another during
anaphase of meiosis I, when the homologous pairs of chromosomes separate. During
anaphase I, homologous pairs are drawn apart, and
they go in the direction of the opposites of the cell. Meiosis I finishes
with the manufacture of two haploid daughter cells for the reason that
the homologous pairs of chromosomes have been separated.
