The two parts of sedimentary rock formation that include the breakdown and carrying away of existing rock are erosion and weathering. Thus, the correct option for this question is D.
Weathering may be defined as a type of process through which a large rock is gradually broken down into smaller fragments by the action of water, wind, roots of plants, etc. Weathering is of two types:
When the process of weathering may be terminated, the activity of erosion may have occurred. This activity is also carried out by factors like water air, overgrazing of cattle, human activities like deforestation, etc. The main effect of soil erosion is to remove the topsoil which is extremely fertile in nature.
Therefore, erosion and weathering are the two parts of sedimentary rock formation that include the breakdown and carrying away of existing rock. Thus, the correct option for this question is D.

Answer:
Explanation:
A) to determine amino acid sequence of the protein produced by that gene. We will use cDNA library, we will hybridize given part of DNA sequence ( as this part only contains exon part). Than we will isolate the hybridize part and translate this sequence using generic coding table.
B) for determine presence or absence of introns in gene used isolated cDNA in first question. Now we will add this cDNA to DNA library. Here cDNA due to complementary mature binds with DNA. If cDNA binds completely with gene with out looping part of gene it shows that gene is having only exons .
And if along with hybridization part some looped part present in between-- it shows both exons and intron are present.
C) for determining alternative splicing we will use cDNA library.
d) to determine length of mature mRNA which includes both the UTR and poly A sequence we will go for cDNA cloning and look for particular cDNA complementary to DNA segments. And later we isolate that cDNA and examine its whole length
E) to determine which cells in the tribble body express this particular mRNA . We use fluorescent tagged small DNA part provided. Then we will add this DNA probe to supplied tribes. The cells which are expressing , will have cDNA will bind to probe and florescent can be detected. Cells which are not expressing that gene, here probe will not bind and no fluorescence.
F) to determine that whose blood strain is this. We will do VBTR profiling . Which VNTR profiling similar to belief stain help to determine which blood stain is this.
Decomposers
Producers
Heterotrophs
Answer:
The correct answer is - Mitochondria.
Explanation:
Mitochondria is the location that stores the energy in food until it is released. It is the cellular organelle that is the place where the cellular respiration process takes place.
In this organelle, the stored food is converted into a usable energy form, ATP. Mitochondria is also known as the powerhouse of the cell as it converts and releases the energy from the stored sugar or food.
Thus, the correct answer is - mitochondria.
B. the integration of the bacteria's genome with the viral genome outside of the bacteria's cell wall.
C. the integration of the viral genome into the ribosomes present in the bacteria to direct protein synthesis for the capsid formation.
D. the integration and stabilizing of a virus into its capsid, which provides protection until conditions are better for reproduction.
Answer:
The correct answer is A. the integration and stabilizing of the lambda 1 phase into a host cell's genome.
Explanation:
Viruses have two reproductive cycle i.e, lytic and lysogenic cycle. During the lysogenic cycle, the viral genetic material gets incorporated into the bacterial DNA and gets replicated with the bacterial genome using bacterial molecular machinery.
During the lytic cycle, the viral protein is expressed which forms the progeny phages which release from the cell through cell lysis. Then the new phages infect other cells. Therefore during the lysogenic cycle, integration and stabilization of the viral genome in the host cell's genome occurs. Therefore the right answer is A.
Answer:
boron, silicon, germanium, arsenic, antimony, and tellurium.
The correct answer is option A, It will decrease in number
Reason -
Since the red-cockaded woodpecker, depends for its fooding on insects which are found in the trees. As the trees are removed, the insects get simultaneously removed. Now the woodpecker will not get food for feeding itself so the first and foremost affects that will take place is the depletion of woodpeckers due to non-availability of foods. However, after certain period of time the woodpecker population may shift to a new location with appropriate food for survival.
