5 0

1. The answer is; B

Transcription is part of the central dogma. It is conducted by the RNA polymerase enzyme that adds complementary bases too, the DNA is transcribed, on growing RNA strand. The RNA is processed (such as splicing) and the mRNA is then used to produced proteins in the process of translation conducted by ribosomes.

2. The answer is; C

Pollution is made up of individuals of the same species, while the community is made of an amalgamation of different species that interact. An ecosystem is composed of a community and its interaction with the biotic and abiotic factors in the environment and habitat.

3. The answer is; B

Helicases are important enzymes in DNA replication because they unzip the DNA strand and allow for the DNA polymerase to access the single strands and replicate the DNA. They use the energy from ATP to break the hydrogen bonds between the two strands.

4. The answer is; B

The climate in the temperate forest is ideal for most life because they receive rainfall throughout the year while the temperatures also remain at a small optimum range throughout the year. This is capable of supporting  a wide variety  of vegetation and hence also support a large variety of animals.

5. The answer is; C

Many food chains interconnected together make up a food web. A food chain begins with primary producers which are mainly photosynthetic plants. These plant harness the energy of the sun into biomass. The transfer of this energy and biomass occur mainly through interactions such as predation. Primary producers are consumed by primary consumers that are consumed by secondary consumers that are consumed by tertiary consumers.

In the term trace element, the adjective trace means that
Margarita [4]

Answer:

The elemental is required in very small amount. (Ans. A)

Explanation:

Trace element is also known as micro-nutrient. It is also defined as any chemical element required by living organisms in a minute or small amounts which is usually part of the vital enzyme (cells produced by catalytic protein).

Exact needs of trace elements vary among species, like commonly required plant trace elements are cooper, zinc, manganese, boron, and molybdenum. Animals commonly required iodine, manganese, and cobalt.

Absence of necessary plant trace elements required by plants in the soil causes deficiency disease, lack of animal trace elements used by animals in the soil may not harm plants, but, animals feeding on those plants develop their deficiency disease.

So, the adjective trace means that the elemental is required in a very small amount.

During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. ... During interphase, the cell grows and the nuclear DNA is duplicated.

Advantages of constant body temperaure
Leya [2.2K]
Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life. 

Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm. 

The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size. 

The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.
