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.
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.

has occurred? Explain how you know.
Finish the sentence
Limestone changing into marble is a type of
(contact/regional) metamorphism since
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.
Therefore, limestone undergoes regional metamorphism to develop into marbles.

Why are there less secondary consumers in an ecosystem than producers? (1 point)
There isn't enough energy available to support more secondary consumers.
Around 90% of energy from one trophic level to the next is available.
More tertiary consumers will eat secondary consumers over producers.
There is less land to use for habitat after the producers grow.
Answer: There isn’t enough energy available to support more secondary consumers.
Explanation:
There isn’t enough energy available to support more secondary consumers.
What are secondary consumers?Organisms that consume primary consumers for energy are known as secondary consumers. Herbivores, or species that only consume autotrophic plants, are always the main consumers.
Secondary consumers, however, might either be omnivores or carnivores. Omnivores consume both plant and animal stuff, while carnivores solely consume other creatures.
Secondary consumers can be found in almost every environment on earth and occur in a wide variety of sizes and shapes. The severe habitats that secondary consumers reside in include icy tundras, parched savannahs, and arctic lakes.
Therefore, There isn’t enough energy available to support more secondary consumers.

Muscle twitching can be explained by the temporal summation action of synapse. Thus, the correct option is B.
What is Muscle twitching?Muscle twitching is also called as muscle fasciculation. Muscle twitching involves a small muscle contraction in the body muscles. Muscle twitches are caused by the muscles tightening up or contracting involuntarily. In other words, it occurs when we are not actually controlling their actions. Muscle twitches can happen for a lot of reasons, such as stress, too much caffeine, a poor diet, exercise, or as a side effect of medicines.
Temporal summation is a physiological effect when the second muscle twitch becomes much higher than the first twitch, forming a tension in the muscle fiber. This happens because, after the first twitch of the muscle, the second stimulation is applied before the muscle even relaxes however both the stimuli are of equal strength.
Therefore, the correct option is B.

principles of international code of botanic nomeclature
Answer:
International Code of Botanical Nomenclature Principles:
1- Independence
2- Classification based on the type
3- Priority
4- Uniqueness
5- Latin use
6- Retroactivity
Explanation:
The six principles of the International Code of Botanical Nomenclature (ICBN) are as follow:
1- Independence principle: botanical nomenclature is independent of other nomenclatures. This means that all plants must be classified in accordance with the ICBN rules, without exception.
2- Classification based on the type: classification is based on nomenclatural types (selected types are referred to as syntypes).
3- Priority principle: the priority for the nomenclature of a particular taxonomic group is determined by its publication.
4- Uniqueness principle: there exists only one specific name for each taxonomic group.
5- Latin use: scientific names must be Latinized or treated as if they were in Latin.
6- Retroactive rule: it is imperative to consider the consequences of proposed changes in names already published.

Explain what will happen to the red blood cell if it is placed in a solution that is 90% water and 10% salt. Is the cell hypotonic or hypertonic to the solution?
Answer:
Hypertonic, and the cell will burst.
Explanation:
Assuming that the red blood cell has equal concentrations of water and salt at the start, the cell has a greater percentage of solute concentration than the solution that it's placed in, which makes the cell hypertonic to the solution. Because of this, water from the solution will diffuse into the cell, going from an area of low solute concentration to high solute concentration. As the water rushes into the cell, the red blood cell will burst.
When the red blood cell is placed in a solution that is 90% water and 10% salt, this will lead to a hypertonic solution and the cell will burst.
Red blood cells refer to the form of blood cell that is found in the blood and made in the bone marrow. A protein that's referred to as haemoglobin can be found in red blood cells. This is important to the human body as it helps in carrying oxygen from the lungs to other parts of the human body.A hypertonic solution refers to a solution that is made up of more dissolved particles like salt than what is contained in a normal cell.In this case, if there is an equal concentration of salt and water, then the addition of water and salt will make the concentration hypertonic since there's a higher concentration of salt.In conclusion, there is an increase in water which will lead to the water diffusing into the cell and will eventually burst the red cells due to the rush of the water.

After disrupting the CCR5 gene in the two macrophages cell lines 4 and 7 (now called edit 4 and edit 7), what will be your next experimental step to verify that these cell lines are now HIV-resistant macrophages?
Answer:
cell lines should be resistant to HIV infection, thereby preventing its integration into the host genome. In consequence, verification can be done by measuring intracellular HIV DNA declines (for example, by real-time quantitative PCR).
Explanation:
HIV (human immunodeficiency virus) is an RNA retrovirus that infects components of the human immune system including, among others, macrophage cells. After infection, the HIV genome is reverse transcribed into DNA and integrated into the genome of the host cells, thereby enabling virus to replicate its genetic material and synthesize protein viral components. Monocyte-like cell lines are able to differentiate into macrophages. When immune cell lines (both monocyte and macrophage cell lines) become resistant to this virus, HIV genome integration is inhibited, affecting the replication cycle of HIV. Thus, it is possible to verify that viral integration did not occur by measuring intracellular HIV DNA declines.

Breaking down of ATP or ___________of the ATP returns the myosin molecule to the high energy conformation.
Answer:
Hydrolysis
Explanation:
Actin is a protein that forms thin filaments which are part of the contractile apparatus in muscle cells. In these cells contraction is triggered by the interaction between actin filaments and myosin filaments that produces their movement relative to one another, a process that requires adenosine triphosphate (ATP). In the first place, myosin-ATP binding causes myosin heads to release actin. Subsequently, ATP hydrolysis induces a conformational change in the myosin filament, thereby myosin 'walks on the actin filament' as the muscle is contracted. After ATP hydrolysis, myosin filaments return to its high-energy configuration.
Earthquake damage depends on many factors including the location of the epicenter where would an earthquakes epicenter be in this diagram
Answer:
A. On Earth's surface, directly above where the fault slippage begins.
Explanation:
The subsurface location where an earthquake begins is known as the hypocenter or focus. The epicenter is the point straight above the focus on the Earth's surface. The correct option is A.
What is earthquake epicenter?The epicenter is the point on Earth's surface that is vertically above the hypocenter (or focus), which is the point in the crust where a seismic rupture commences.
The seismic waves that cause the ground to shake are caused by this abrupt energy release.
The plates or blocks of rock begin to move during and after the earthquake, and they continue to move until they become stuck again. The focus, or hypocenter, of an earthquake, is the location underground where the rock first breaks.
The hypocenter or focus is the subsurface location where an earthquake begins. On the Earth's surface, the epicenter is the point directly above the focus.
Thus, A is the correct answer.

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.
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.
In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are expected from a cross between two heterozygous shorthaired rabbits? I need you to fill out this chart I got the answer to the ratios
Answer:
Answer:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair 3/4
ss 1/4 Long hair 1/4
Explanation:
Both are heterozygous for the trait so we can expect that the cross would be:
Ss x Ss
S s
S SS Ss
s Ss ss
So the resulting off-spring would have the following genotype and phenotype:
1 out of 4 will have a genotype of SS.
2 out of 4 or half will have a genotype of Ss.
1 out of 4 will have a genotype of ss.
But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:
Short hair: 1/4 + 2/4 = 3/4
Long hair: 1/4
So in summary:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair
ss 1/4 Long hair 1/4
Explanation:
