Answer:
The correct answer is - They secrete acid that breaks away rocks
Explanation:
Lichen causes chemical weathering to break the rocks quickly which is the excretion of various acids like oxalic acid and many more organic acids that can cause a significant impact on the rock by dissolving minerals.
By breaking the rocks it forms the ground for the plant that will come later in place of the bare rocks by this chemical weathering process. An example of chemical weather is a change of the granite to clay with the help of hydrolysis.

Explain how signaling pathways are deactivated for transduction parts of a signaling pathway.
Explanation:
cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response. cAMP signaling is turned off by enzymes called phosphodiesterases, which break the ring of cAMP and turn it into adenosine monophosphate (AMP).

1.Which type of rock may result when sedimentary rock is exposed to extreme heat and pressure?
a. clastic
b. extrusive
c. igneous
d. metamorphic
2. In the rock cycle, how does rock become sediment?
a. Through weathering and erosion
b. through crystallization and solidification
c. through heat and pressure
d. through compaction and cementation
3. A Sedimentary rock containing a fern fossil was found. what does this tell about the area at the time the rock was formed?
a. The area was hot
b. The area was covered by and ocean
c. The area was cold
d. The area was on a land
Answer:
1:(D), 2:(D), 3:(D)
Explanation:
1) When a rock is exposed to heat and pressure, it becomes a metamorphic rock. This is correct, because this is the process that forms a metamorphic rock.
2) A rock becomes sediment through weathering and erosion. In this question, they are not asking you to explain the process of sedimentary rock formation, they are asking you how a rock becomes sediment. The process of weathering and erosion breaks down a rock, and turns that rock into smaller peices, which therefore, through the process of compaction and cementation forms a sedimentary rock.
3) A fern is a land plant. It is not found in the sea and there is not enough information given to tell whether or not the area was hot or cold. This leaves us with D. We can tell that this fossil is a land fossil because ferns do not grow in the ocean.

Coding of a Polypeptide by Duplex DNA The template strand of a segment of double-helical DNA contains the sequence (59)CTTAACACCCCTGACTTCGCGCCGTCG(39) (a) What is the base sequence of the mRNA that can be transcribed from this strand
Answer:
GAAUUGUGGGGACUGAAGCGCGGCAGC
Explanation:
The process whereby a mRNA molecule is formed from a DNA template is called TRANSCRIPTION. The mRNA formation follows the complementary base pairing rule which says that Adenine is bonded to Thymine (Uracil in RNA) i.e A-T(U) while Guanine is bonded to Cytosine i.e. G-C.
Based on this, a DNA molecule with base sequence: CTTAACACCCCTGACTTCGCGCCGTCG will be transcribed into a mRNA strand with base sequence: GAAUUGUGGGGACUGAAGCGCGGCAGC

in a punnett square the alleles of all the male gametes are entered in the
a. top of the chart
b. right column
c. left column
d. bottom left box
Answer:
In a Punnett's square the alleles of all the male gametes are entered in the top of the chart (option a).
Explanation:
Punnett square was designed to plot the allele crosses of the parental generation and observe the probable combinations of the alleles in the offspring, for a given characteristic.
Conventionally, in a Punnett square or chart, the father's alleles are placed at the top, the mother's alleles are placed in the left column and the results in the offspring are shown in the boxes, resulting from the intersection of the data.

In the ionic compound KF, what is the charge on K?
positive
partial positive
negative
ООО
partial negative
no charge
Answer:
Charge on K is +1.
Explanation:
This gives potassium eight valence electrons in its third energy level, and flourine eight valence electrons in its second energy level. This also produces a potassium cation K+ with +1 charge and a flouride anion F- with -1 charge.

In the analysis of quantitative traits, positions on chromosomes called quantitative trait loci (QTLs) are often discussed. In the same context, restriction fragment length polymorphisms (RFLPs) are also discussed. What is the relationship between QTLs and RFLPs
Answer:
RFLP technique can be used to develop useful polymorphic molecular markers for mapping QTLs.
Explanation:
A quantitative trait locus (QTL) is a fragment of DNA whose variation is associated with phenotypic traits controlled by numerous genes (i.e., quantitative traits) such as, for example, height, weight, etc. Restriction fragment length polymorphism (RFLP) is a technique useful to detect DNA polymorphisms (i.e., genetic variation) among samples. In RFLP, the genome is digested using restriction enzymes and these restriction fragments are subsequently separated by electrophoresis depending on their size, thereby producing differential gel bands among samples. These polymorphisms can be used to map QTLs and develop linkage maps, which is known as RFLP mapping.
What is true about the two daughter cells formed after the binary fission of a bacterium cell?
1.They have variations in the primary DNA but have the same set of plasmids.
2.They have variations in the primary DNA but may have a different set of plasmids.
3.They have the same primary DNA and the same set of plasmids.
4.They have the same primary DNA but may have different plasmids.
Answer:
They have the same primary DNA but may have different plasmids.
Explanation:
i took a test and got the question right
The option that's true about the two daughter cells formed after the binary fission of a bacterium cell is D. They have the same primary DNA but may have different plasmids.
Binary fission simply means asexual reproduction when a body is separated into two different bodies.
It should be noted that during binary fission, the genetic material of an organism is duplicated and this enables the two new organisms formed to be able to have their separate copy of DNA.
In a bacterium cell, when the two daughter cells are formed after the binary fission, they have the same primary DNA but may have different plasmids.
