The right answer is D) photosynthesis in plants
Cellular respiration does not produce oxygen, it consumes it rather. The same for the respiration of animals and the human being.
The degradation of organic matter does not produce oxygen.
Photosynthesis is the only one of these proposals that produces oxygen, and this process belongs to the plants.
<span>The answer is Letter D. plasma membrane. The plasma membrane can be seen in the outer most layer of the cell and in plant cell it is present just beneath the cell wall. Plasma membrane is describe as a biological membrane or an outer membrane of a cell, which is composed of two layers of phospholipids and embedded with proteins.</span>
The answer is e. Myoglobin has a single
polypeptide chain so it has 10, 20, 30 and 40
structure.
Myoglobin is an iron and an oxygen binding
protein. It has a single polypeptide chain.
Proteins with the single polypeptide chain
cannot have quaternary (40) structure. 40
structure of proteins includes an arrangement of
multiple folded polypeptide chains (subunits) in
a multi-subunit complex. Therefore myoglobin
cannot have 40 structure as the single chain
polypeptide. All other choices are correct.

Hydrophilic means "water-loving," which means that hydrophilic molecules readily associate with polar molecules such as water.
Answer:
I) Sexual reproduction
II) Mutation
Explanation:
Variations refer to the difference observed within organisms of the same species. Variation are introduced into a population by:
- new genetic combinations that occur during sexual reproduction (i.e during meiosis)
- mutations, spontaneous changes that occur in genes and chromosomes.
