The correct answer is B. unicellular.
Dinoflagellates are unicellular or multicellular, producers, and autotrophs, and apple trees are multicellular, producers, and autotrophs. All plants have numerous cells in them, so they can never be unicellular. The remaining characteristics they share with less complex organisms such as dinoflagellates.
Answer: Option C) blocks oxygen transport in human blood
Explanation:
Carbon monoxide (CO) is one of the oxides of carbon formed when fuel is incompletely burned. It can be generated from exhaust pipe of vehicles, electric generators.
When inhaled CO attaches to the hemoglobin portion of the red blood cells, forming a bound complex called CARBOXY-HEMOGLOBIN, that is unable to transport oxygen to the body tissues.
Thus, by this mechanism Carbon monoxide blocks oxygen transport in human blood
Answer:
Elastin
Explanation:
The elastin is defined as an extracellular matrix protein which lends to the elasticity and also resilience to the tissues such as the lungs, skin, arteries, tendons, and the ligaments.
Elastin synthesized from precursor molecule named tropoelastin.
Elastin is the fibrous protein which gives the skin its flexibility and also helps the skin regain its shape.
<u>Answer:</u>
All the individuals of a species that live together in one place at the same time is called as population.
<u>Explanation:</u>
- When organisms of same group or species live in a particular area they are defined as population.
- Along with living in a particular area the species should also have the 'capability of interbreeding' in order to be called as population.
- Demography is a social science that deals with the 'statistical study of population'.
- A term 'sex population' is often visualized in 'population genetics', it refers to a organisms group in which a 'pair of members' can breed together.
Answer:
The correct answer is option B.
Explanation:
The light-dependent reactions in the process of photosynthesis utilize Sun's light energy to dissociate water, known as photolysis. Water after getting dissociated produces hydrogen, oxygen, and electrons. The electrons move through the compositions in the chloroplasts and by the process of chemiosmosis, produce ATP.
The hydrogen gets transformed into NADPH, which is further utilized in the light-independent reactions. While oxygen diffuses out of the plant as a waste component of photosynthesis into the atmosphere. All this takes place in the grana thylakoids of the chloroplasts.
