Answer: Mechanical Isolation
Explanation:
Mechanical isolation is a type of barrier that prevents the species that are closely related from mating with each other.
It is used in case of plants and animals(here beetles) in which the without compatible sex organs individual of different species will not be able to mate and produce offspring.
Thus, the correct answer is option C
A food chain can usually sustain no more than six energy transfers before all the energy is used up. And so less energy is transferred at each level of the food chain so the biomass gets smaller.
Answer:
02.5 N
Explanation:
02.5 N is a derived unit of measurement.
A derived unit is one that is obtained by combining two or more fundamental units.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
Combining the two; kg x m/s² = kgms²
1N = 1 kgms²
kg, m, k and N are fundamental particles
Answer:
Carbohydrates, proteins, lipids and nucleic acids.
Explanation:
Biomolecules are organic and are carbon containing and are of four types which are carbohydrates, proteins, lipids and nucleic acids.
Carbohydrates are part of our major diets and are found in grains, fruits and vegetables and so on.
Carbohydrates are energy producing food through glucose.
Lipids contain both fat and oil and they are hydrocarbon and non polar molecules that don't dissolve in water. They provide energy, insulation in the environment and are major constituent of plasma.
Proteins are organic molecules found in meat, milk, beans, cheese e.t.c.
They are body building food or serve as building blocks.
They are enzymes and hormones which are involved in body mechanisms.
Nucleic acids are composed of deoxyribonucleic acid(DNA) and ribonucleic acids. They are the genetic constituent of living organisms and they carry the genetic information.
