Answer:
According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).
Explanation:
Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.
When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.
A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.
The other options are not correct because:
<em> 1.Carbohydrate is a biomolecule that is not involved in the genetic process.
</em>
<em> 3. Ribosome is where protein synthesis occurs.
</em>
<em> 4. Chromosome is the complete DNA molecule.</em>
Answer:
Explanation:
A habitat (which is Latin for "it inhabits") is an ecological or environmental area that is inhabited by a particular species of animal, plant or other type of organism. ... Human habitat is the environment in which human beings exist and interact. For example, a house is a human habitat, where human beings sleep and eat.
Answer:
Density is nearly 3 cabs per hectare
Explanation:
Given -
There are three three intertidal regions.
Area of each intertidal region is 
hectares.
Number of crab in the intertidal regions are as follows -
Intertidal region I - 7
Intertidal region I - 2
Intertidal region I - 6
Sum of crabs in all three regions is equal to
Total area of all three intertidal regions is equal to
hectares
Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions
Density 
Density is nearly 3 cabs per hectare
Answer: Yes
Environmental problems like pollution has a solution. To curb this, measures must be put in place in making sure waste management agencies are establish. The work of these agencies will be handling wastes and disposing them at the best strategic places apportioned for this very purpose which will be in the outskirt of residential areas to avoid inhaling of toxins that emanates from these rubbish.
There are three types of energy involved in a muscle's contraction. There is metabolism, catabolism, and anabolism. Metabolism is the events that are carried out in the human body to create energy and other things needed for activity. Catabolism is the process during the organic matter is broken down and the energy is released, it takes place during increased movement. Anabolism is the energy-consuming process that substances are created, it takes place when there is little movement. All three of these work to gather in muscle contraction.
