choli [55]3 years ago
6 0

Answer:

A

Explanation:

A. The optimum pH of the enzyme is 6.6.  - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)

B. The optimum pH of the enzyme is 5.8.  - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80

C. The enzyme's activity is greater around pH 8.0 than around  pH 5.0  - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.

D . The enzyme's activity continually increases as pH increases  from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

Which phrase describes radiation? transfer of heat by the actual movement of warmed matter transfer of heat between two objects
Andrews [41]

Answer:

The answer is: the process in which energy is emitted by one object, transmitted through space, and absorbed by another.

Explanation:

Heat energy- <em>this is the movement of tiny particles in the different phases of matter. </em>It can be transferred through different processes such as <u>convection, conduction and radiation.</u>

Let's focus on radiation. In this process, a body emits energy, then this energy is transmitted through space and is absorbed by another body. The heat, in here, is carried by electromagnetic waves. Examples of electromagnetic waves are <u><em>visible light, X-rays, radio waves, etc.</em></u>

For example, when you light a candle, it emits a visible light which is transmitted through space. Heat will only be transferred to a body if the body moves closer to the candle. So, if I put my finger closer to the candle, it will absorbed the heat. This process is called radiation.

the interaction generated by human intervention to protect the gray wolf population in the northwestern united states can be def
lina2011 [118]
Commensalism is defined as a relationship between two species where one has certain benefits from the relation and the other is unaffected. So, in this case, it is hard to determine what kind of relationship the gray wolf  and human populations have because when people intervene to help protect a species they are officially unaffected, they do not lose or gain anything, but the gray wolf is one of the key species in their ecosystem, so protecting them is beneficial for the ecosystem, therefore can have numerous positive effects on human-environment too.

This is failure of chromosomes pairs to separate properly during meiosis is ?
vova2212 [387]
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.[1][2][3] Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
