c- the must use anzymes ecoded by theviras itself.
d- they invariably kilang cell they infect,
Answers
Answer:
b. They cannot reproduce outside of a host cell.
Explanation:
Viruses are parasitic organisms that need a host in order to thrive and reproduce. This means that they cannot replicate outside of a host cell, but can only do this by parasitizing it. They have to find a host cell in order to continue their life-cycle or else they won't thrive. The word "obligate" means being restricted to a specific mode or function in life. This shows that the virus has a restriction when it comes to reproduction. It cannot reproduce without finding a host cell.

AP Biology (a) Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produce a SIRT3 protein of correct sequence, but if an mRNA were transcribed from the nontemplate strand of the SIRT3 gene in these cells, it would not produce a SIRT3 protein of correct sequence.
Answers
Answer:
The nontemplate strand of the SIRT3 gene would encode an mRNA with a sequence complementary to the SIRT3 transcript
Explanation:
Within the cell nucleus, the RNA Polymerase II (RNAPII) binds to the non-coding DNA strand in order to transcribe a precursor messenger RNA (pre-mRNA) sequence that is directly complementary to the target DNA region (with the exception of Uracil instead of Thymine). This pre-mRNA is then processed to form mature mRNA. The coding DNA strand is the DNA strand whose base sequence is identical to the mRNA synthesized, thereby the nontemplate strand is referred to as the coding strand. Subsequently, mRNA leaves the cell nucleus and travels to the ribosome in the cytoplasm, which uses this information to be translated into the corresponding protein.
An mRNA transcribed from the template strand of the SIRT3 gene produce a correct sequence of SIRT3 protein because of complementary rule.
DNA Complementary rule:
It is the phenomenon where specific Nitrogenous bases bond with certain bases only.
So, this produce two type of strands, Non- template strand and Template strand.
Template strand form mRNA sequence which is similar to the non-template strand because of the complementary of DNA.
Therefore, an mRNA transcribed from the template strand of the SIRT3 gene produce a correct sequence of SIRT3 protein.

Which of the following outcomes will most likely result from the irreversible binding of GDP to the G protein?
Answers
Answer:
The correct answer is - The intracellular concentration of glycogen will increase.
Explanation:
The intracellular concentration of glycogen will increase as the result of the irreversible binding of GDP to the G protein due to the not respond to the binding of norepinephrine to the beta-adrenergic receptor which prevents the separation of the G protein alpha subunit.
This leads to the activation of adenylyl cyclase. PKA will be lesser and glucose 1 phosphate as the dissociation of G protein will not take place and ultimately to glycogen accumulation.
The most likely result from the irreversible binding of GDP to the G protein results in an increase in intracellular concentration of glycogen.
G proteins are a group of proteins that operate as signaling molecules inside cells, conveying signals from various external stimuli to the cell's core. They govern their signaling cycle with the help of GDP.
In an irreversible binding of GDP to the G protein, the G protein is rendered inactive.The GDP is swapped by GTP to initiate the protein, and the G protein then sends out its signal.This results in an increase in the intracellular concentration of glycogen because of the non-response to norepinephrine binding and to the beta-adrenergic receptor, which inhibits the G protein alpha subunit from being separated.

if the number of birth in a population is the same number of deaths in a population what will happen to the growth of population?
A. It will increase
B. It will decrease
C. It will stay the same
D. It will fluctuate
Answers
Answer:
C. It will stay the same
Explanation:
Let's say the population is 7
Then let's say 4 more are born, and since the number of births and deaths are the same then the number of deaths must be 4.
Since the number of births is positive and the number of deaths are negative then they cancel out and the population number stays the same.
Therefore C is correct.
If the number of birth in a population is the same number of deaths in a population, the growth of the population will stay the same. Thus, the correct option for this question is C.
What is Population?A Population may be defined as a group of individuals belonging to the same species living in the same area at a particular time.
The characteristics of the population like size, birth rate, death rate, population dispersion, age distribution, etc. cannot be applied on the individual level. But these factors can be significantly represented on the graph and hence, they are known as demographic factors.
The growth rate of the population can be measured by two factors such as birth rate and death rate. When the birth rate is greater than the death rate, the growth of the population will increase. But when the birth rate is lower than the death rate, the growth of the population will decrease.
Therefore, if the number of birth in a population is the same number of deaths in a population, the growth of the population will stay the same. Thus, the correct option for this question is C.

Some aquatic organisms that live in cold environments similar to that of crabs have multiple forms of certain enzymes that catalyze reactions at various temperatures. Explain how having multiple forms of enzymes would contribute to the fitness of these organisms.
Answers
Answer: The multiple forms of enzymes help in maintaining the homeostasis in cold environment.
Explanation:
The homeostasis is the process or the ability of the body to maintain the internal environment constant with respect to the changes occurring in the external environment. Some aquatic organisms which survive in cold water environments are required to maintain the homeostasis to survive. Multiple enzymes help them to maintain the homeostasis. Such enzymes allow the catalytic break down of fats and other biomolecule to generate internal body heat so that the aquatic organisms like crabs can maintain their body temperature constant with respect to the cold environment, this is a kind of adaptation.

The change in limestone into marble is a type of regional metamorphism. Almost all types of sedimentary rocks can undergo metamorphosis to form metamorphic rocks.
What is Regional Metamorphism?
All types of rock can undergo metamorphosis, to produce different types of metamorphic rocks. Limestone if one of those sedimentary rocks which can be changed into marble, shale and the mudstones into slate, and igneous rocks like granite which can later on turn into the gneiss.
Regionally metamorphosed rocks usually have a squashed, or a foliated appearance on their surface, which is an example that includes slate, schist and gneiss, formed by the metamorphism of mudstones, and also from the marbles which are formed by metamorphism of limestone.

Which factor can increase the chances of a species evolving by natural selection?
A. high reproductive rate
B. no related species
C. stable environmental conditions
D. small gene pool
Answers
Answer:
A.
Explanation:
A high reproductive rate means a larger gene pool, and traits which benefit stand above the rest better, and are kept in the population. No related species would allow for only the small gene pool to continue in a slow evolutionary pace. Stable ecosystem does not generally require an organism to adapt.
The factor that can increase the chances of a species evolving by natural selection is genetic variation. Therefore, option "A" is correct.
What is genetic variation?The difference in the gene sequence can be between interspecies and interindividual. The primary force behind the process of natural selection is genetic variation. Gene variation is the result of different forms of alleles.
The variants which result in genetic alternation are single nucleotide polymorphisms or variation, copy number variation, structural variation, translocation, insertion, deletion, and inversion. These result in the formation of different alleles resulting in genetic variation.
Therefore, genetic variation results in different skin colors, and hair colors.
