bcuz i said so and this
Answer:
<u>Folding and faulting-</u> The process in which the layers of the Earth are displaced or moved into a different position due to some forces acted upon them, as there are different reasons due to which the folding and faulting occurs.
- The forces are so power full that they can bring the sediments of ocean to level or elevation above the sea level and can have a destructive effects for the living being. As there are various causes for folding and faulting of these layers,some of these forces are given below;
Explanation:
<u>Geological events causing the folding and faulting-</u>
<u>Tectonic Plates movement-</u> The parts of the Earth layer are always sliding over each other, and when they do they produce huge seismic waves. Which then causes the earthquakes, the folding and faulting of these layers.
<u>Volcanic eruptions : </u>It happens rarely as the number of gases and lava from inside the Earth, down from the crust move upward and erupts, producing dust in the atmosphere.
The other two geological causes are;
- <u>Intrusive igneous activity,</u>
- <u>subduction.</u>
- <u></u>
Answer:
A. I, II, III, and V only
Explanation:
In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,
- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.
- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.
- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.
Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).
Chemicals produced by bacteria that limit the growth of other bacteria are called antibiotics.
Answer:
Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
Explanation:
Similarity
Both the aldehyde and ketone have C=O group
Difference
In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO
while in ketone the function group is C=O only that is bonded to two carbon atoms.
Example
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
