Answer;
The two processes used by producers to obtain energy are photosynthesis and chemosynthesis.
Explanation;
Producers are those organisms that can make their own energy in an ecosystem using biochemical processes. These biochemical processes are photosynthesis and chemosynthesis.
Photosynthesis involves use of energy from the sunlight together with water and oxygen to make simple sugars. The process converts solar energy to chemical energy (simple sugars).
Chemosynthesis involves use of chemicals as the energy source, rather than sunlight , to make simple sugars such as glucose.
Glucose from both processes is then used for respiration to generate energy or stored in form of starch.
Answer:
allopolyploidy
Explanation:
Polyploidy is the condition by which a cell might have more than two chromosome sets that form homologous pairs. It might occur due to a failure or abnormality in cell division.
Autopolyploidy
Refer to a type of polyploidy in which an organism has more than two copies of homologous chromosomes. It results from the duplication of a group of chromosomes of the same species. Autopolyploid individuals have <u>at least three groups of homologous chromosomes</u>. Autopolyploidy is produced by the<u> gamete fusion of the same progenitor - same species</u>-, duplicating the number of chromosomes of diploid species. The autopolyploid cell has groups of homologous chromosomes. Autopolyploidy is produced mainly due to non-disjunction during meiosis.
Allopolyploidy
Refer to another type of polyploidy in which species have more than three sets of chromosomes in their cells. Allopolyploidy <u>occurs when two different species mate</u>, leading to the fusion of gametes that belong to different species and produce a new hybrid. The chromosomic complement has more than two copies of chromosomes. The hybrid is infertile with the parental species. The allopolyploid cells have chromosome groups that are not homologous.
In the exposed example two different species mate and produce a hybrid species.
Answer: silence point
A silent point mutation may be an effect of a base-pair substitution (substitution of one base pair with another in DNA). However, silent point mutations are a special case where no amino acids are affected. As a result, since the monomers of proteins are amino acids, there is no change to the sequence of a protein.
Given Question:
Can prokaryotes exchange genes with each other?
Answer: <u>True</u>
Explanation:
By the process of conjugation, their DNA is <u>transferred</u> from one prokaryote to another by means of a pilus, which brings the organisms into contact with one another. The DNA transferred can be in the form of a plasmid or as a hybrid, containing both plasmid and chromosomal DNA.
