proteins
lipids
nucleic acids
Answer:
Proteins.
Explanation:
Protein is one of the major biomolecule of living organisms and acts as a main building block of the body. Proteins are the polymers of amino acids.
Most of the enzymes present in living organism are made upof proteins. Antibodies made up of heavy and light chains are the constituent of proteins. Hormones like insulin, glucagon and epinephrine are proteinaceous in nature. Muscle contains protein like actin, myosin and nebulin. Hence, protein can act as antibody, enzyme, muscle and hormone.
Thus, the correct answer is option 2.
What does the model represent?
A. How plants transform light into stored chemical energy
B. How energy is released from sugar molecules
C. How the sun delivers thermal energy to earth
D. How bacteria transform nitrogen into a usable from
Answer: The correct answer is-
A. How plants transform light into stored chemical energy.
The given equation in the model of the represents word equation for photosynthesis.
Photosynthesis is a process of formation of food ( that is a carboydrate) in green plants and algae using CO2 (carbon dioxide) and H2O (water) in the presence of sunlight.
During this process, a green pigment in the chloroplast called chlorophyll, absorbs solar energy and converts it into chemical energy in the form of ATP and NADPH.
In the next phase, which is a light independent phase ,the chemical energy is utilized in the formation of glucose, which is a food molecule for green plants and algae.
Thus, option A) is the right answer.
Competition between two species may force one of them to migrate to survive.
Disease may lead to a decline in the reproductive rate of the species’ main predator.
Lack of water during a drought may cause many of the individuals in a population to die.
Answer:
The most appropriate answer would be Competition between two species may force one of them to migrate to survive.
Competition is a type of biological interaction in which organisms of same or different species compete for similar resources essential for their survival in an ecosystem.
Organisms can compete for limiting sources (such as air, water, food), territory, and mating rights.
In inter-species competition, species with the slightest advantage will grow and result in the migration or extinction of other species in that ecosystem.
Thus, the population of other species would decrease or extinct in that ecosystem.
For example, lion and cheetah may compete for their common prey that is, deer.
Answer:
B): Competition between two species may force one of them to migrate to survive.
Explanation:
Genetics is the scientific study of genes - the instructions that govern a person's growth, development, and health. These are passed down from from parents to children via sexual production.
_____ eat producer and consumers
Answer:
1)Consumers
2)Omnivores
Explanation:
Primary consumers are animals that eat primary producers; they are also called herbivores (plant-eaters). Secondary consumers eat primary consumers. They are carnivores (meat-eaters) and omnivores (animals that eat both animals and plants).
Omnivores eat both producers and consumers. Most people are omnivores, since they eat fruits, vegetables, and grains from plants, and also meat and dairy products from animals. Dogs, bears, and raccoons are also omnivores
Answer:
A) The main functions of mitosis are growth and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have.
