Answers

Answer 1

Answer:

zooplankton population will increase

Explanation:

fish eat zooplankton so without fish the zooplankton lose their predators and the population will increase. seals have other things they can eat (penguins and sea gulls), and phytoplankton will decrease because there will be more zooplankton to eat them

What is a herbivore?


A. an animal that gets energy from eating other animals

B. an organism that gets energy from eating only plants

C. an animal that gets energy by eating both plants and other animals

D. an animal that eats only herbs

Answers

D.

definition: A herbivore is an animal that gets its energy from eating plants, and only plants.

An herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.

What is the role of the herbivore?

The herbivore is the animal that directly eats the plants of the ecosystem, which are later eaten up by the carnivore, and the herbivore gets more energy than the carnivore as they get energy directly from the plant source. The herbivore only eats plants, and the different ecosystems have different herbivores, such as the land ecosystem, which has the goat, elephant, cow, etc.

Hence, an herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.

.Specific processes must take place within the cell for protein synthesis to occur. The processes that take place within a cell for protein synthesis to occur. Which occurs during translation but not during transcription? A DNA template is used to create an mRNA strand. A tRNA template is used to create a DNA strand. A tRNA template is used to create an mRNA strand. An mRNA template is used to create an amino acid chain.

Answers

Answer:

An mRNA template is used to create an amino acid chain.

Explanation:

Transcription is the first step in the protein synthesis process. Translation is the second.

Overall, the central dogma of biology is DNA->RNA->protein.

Transcription is that first step, DNA to RNA, and translation is RNA to protein: think of it like nucleic acids can just be transcribed, but nucleic acid to protein is like a whole different language, so it has to be translated. So the correct answer here is that mRNA is used to make amino acid chain (aka protein), which happens only in translation.

Which of these is a form of nonrenewable energy?
O A. Fossil fuel energy
O B. Solar energy
C. Wind energy
O D. Hydroelectric energy​

Answers

Answer:

Fossil fuel energy

Explanation:

This is because oil from fossils take a millions of years to form and people won't be able to wait millions of years

Fossil fuel energy is a form of non-renewable form of energy. Thus, the correct option will be A.

What is Non-renewable energy?

A non-renewable energy resource is a natural resource which cannot be readily replaced by the natural means at a particular pace which is quick enough to keep up with the consumption of the energy resource. An example of the non-renewable energy resource is a carbon-based fossil fuel. The original organic matter with the aid of heat energy and pressure generally becomes a fuel such as the oil or natural gas.

There are four major types of the nonrenewable resources which include oil, natural gas, coal, and the nuclear energy. Oil, natural gas, and coal are collectively known as the fossil fuels. Fossil fuels were formed within the Earth from the dead plants and animals over a period of millions of years and hence are named as the fossil fuels.

Therefore, the correct option will be A.

a. ecosystems
b. habitat
c. abiotic factors
d. biotic factors

Answers

Abiotic factors. They are not living yet control the plant’s well being.

Abiotic factors are non-living components of an ecosystem that influence their surroundings. Examples may be light, water, and temperature in a terrestrial habitat, hence option C is correct.

What are abiotic factors?

Abiotic variables are non-living elements that have an impact on the survival, development, and existence of living things, including plants.

We may concentrate on the water as one of these abiotic elements even though there are many others that are equally significant and have a part to play.

Water is one of, if not the most, critical abiotic factors since it is essential for plant existence. Depending on how severe the absence of water is, it will be a limiting factor for a plant's growth or even life.

Therefore, abiotic factors are non-living components of an ecosystem that influence their surroundings, hence option C is correct.
