The characteristic it shows is Growth
The two substance that will be produced if lactaid works properly is
Galactose and glucose
<u><em>Explanation</em></u>
- <u><em> </em></u>Lactaid is a natural enzyme that help to break down lactose
- Lactose are sugar found in dairy food like milk,ice cream or cheese into which are breakdown into simple sugar, that is galactose and glucose that are easily digested.
Gregor Mendel started experiments on inheritance in the 19. century. The basis of inheritance patterns is the fact that diploid cells contain two copies of the genome and that a gene has different variants, called alleles.Alleles can be dominant (for example, marked A) and recessive (for example, marked a). In a gene locus (position of a gene) there are only two alleles, one from the mother and the other from the father.If individuals have two copies of the same allele they are homozygous (AA (dominant homozygous) or aa (recessive homozygous)). If individuals have two different alleles they are heterozygous (Aa).In autosomal dominant traits, the phenotype is present if both copies of the dominant allele (A) are present (homozygous individuals AA) or only one copy of the dominant allele is present (heterozygous individuals Aa).In autosomal recessive traits, the phenotype is present if both copies of the recessive allele (a) are present (homozygous individuals aa).This is complicated in sex-linked trait, because there are two X cromosomes in females and one X chromosome and one Y chromosomes in males, so terms dominant and recessive are not reliable.It should also be taken into consideration that many traits are complex and caused by many genes interaction and/or environment conditions.
Answer:
A <u> theory </u> may be formed from many related hypotheses that have been tested and support the evidence.
Explanation:
<u>A THEORY -:</u> A theory is a well-established, tested explanation that gives some part of the natural world a unified description. A hypothesis is focused on substantiated knowledge, repeated testing, and a large community of scientists / researchers agree on it.
The aim of a theory is to try to understand phenomena that many researchers have examined extensively and carefully over time. A hypothesis does not prove that the "unified description is correct." However, because the theory is the result of scientifically based research, the theory (as opposed to a single hypothesis) is more likely to be correct. Any hypothesis can (and should) be tested, but many trained scientists must scientifically perform and study the experiments.
Answer: The answer is B
Explanation: The ratio decreases from 1.6 to 1.2 because fewer stomata are needed at higher CO, concentrations
