Answer:
Its Photosynthesis (C)
Explanation:
it takes the energy of sunlight and combines water and carbon dioxide to produce sugar and oxygen as a waste product. The reactions of respiration take sugar and consume oxygen to break it down into carbon dioxide and water, releasing energy.
Have a great day :)
Answer:
The correct option is D. Chemoautotroph uses CO2 for carbon and H2 for energy.
Explanation:
Autotrophs can be described as organisms that are capable of making their own food. There are two types of autotrophs: photoautotrophs which use energy from the sunlight to produce food and chemoautotrophs have the ability to make biological compounds from inorganic matter.
The chemoautotrophs are capable of taking carbon from inorganic sources and converting them into useful organic compounds. They are also capable of taking hydrogen atoms and use them for deriving energy. Hence, D is the correct answer.
Answer:
Starfish preys on animals that have no other natural prey. The starfish consume those species so they are removed from the environment.
Answer:
A. The man's genotype is Bb. Phenotypes of the offsprings:- heterozygous brown-eyed- homozygous blue eyedGenotypes of the offsprings:- Bb- bbb. The blue is recessive, so the woman's genotype is bb. It is impossible for her to have B because it is dominant over b.c. The woman can only produce bb or blue-eyed.d. The man's genotype is Bb. It is impossible for him to produce an offspring with blue-eyes if his genotype is BB.e. The man can produce Bb or brown-eyed and bb or blue-eyed.
