Polycistronic mRNA allows for coordinated expression of genes involved in the same pathway and an example is with the lac operon in E. coli.

Polycistronic mRNA refers to a type of messenger RNA molecule that contains multiple protein-coding regions called cistrons or open reading frames.

In other words, it carries the genetic information for the synthesis of multiple proteins within a single RNA molecule.

Each protein-coding region within the polycistronic mRNA is usually preceded by a specific ribosome binding site (RBS) and is typically followed by a termination codon to mark the end of that coding sequence.

One classic example of a polycistronic mRNA is the lac operon in Escherichia coli (E. coli) bacteria.

Homeostasis control in living things is exerted over all of the following except response to stimuli. The correct answer is C.

Homeostasis is the ability of a living organism or cell to maintain a stable internal environment despite changes in external conditions. It involves the regulation of various physiological parameters, such as temperature, pH, fluid balance, moisture level, acidity level, and glucose levels, through feedback mechanisms that help to maintain a balanced and stable state.

This allows the organism or cell to function optimally and respond effectively to environmental challenges or changes. Homeostasis is essential for survival and is maintained by complex physiological and biochemical processes that work in harmony to keep the internal environment within a narrow range of acceptable levels.

However, the response to stimuli, such as sensory input from the environment, is not directly controlled by homeostatic mechanisms but by other physiological processes such as reflexes, sensory perception, and decision making in the brain.

Answer:

amount of copper

Explanation:

The independent variable would be the amount of copper fed into the experimental rats.

An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.

The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.

Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.

Answer:

B

Explanation:

The chart is going up and up which means the car goes up and up in speed and velocity and is very consistant

The statement that is accurate regarding the car trip is that it travels at a constant velocity. The correct option is B.

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

The rate of change of displacement is known as velocity. The rate at which velocity changes is called acceleration.

Due to the fact that it includes both magnitude and direction, velocity is a vector quantity. As the rate at which velocity changes, acceleration is likewise a vector quantity.

An object must move at a consistent speed and direction in order to have a constant velocity.

The object can only move in a straight line if the direction is constant. So, motion in a straight line at a constant speed is defined as having a constant velocity.

Thus, the correct option is B.

Explanation:

Terresterial comes from the greek work "terra", which means Earth. So when you hear the word "terresterial " think that it means "like Earth". More specifically, it means that a planet is SOLID, like the Earth is. So, to figure out the answer to your question, let's list the planets starting with the ones closest to the sun and work out way out toward deep space. We can also describe each planet a bit as we list them.

Mercury - Closest to the Sun and, because of that, its very hot here. A lot of the ground on this planet is lava made of molten metal which is a liquid BUT there is also solid ground so it is terresterial. ✓

Venus - 2nd closest to the Sun. There is ground here, so it's terresterial. ✓

Earth - 3rd closest to the sun. There is solid ground here too so... Terresterial ✓

Mars - Also Solid. Terresterial ✓

Jupiter - Jupiter is made of Gas. If you went there, there would be nothing solid to walk on, but instead simply pass through it like it was a cloud. Therefore it is NOT terresterial

Saturn - Also a "Gas Giant" plant. (They are called gas giants because these planets are huge! You could fit 764 planet Earths inside of Saturn and over 1300 Earths could fit inside Jupiter!) Gas = NOT terresterial

Uranus - Another Gas Giant. Not terresterial

Neptune - The last of the gas giant planets and the furthest from the Sun. Again, its made of gas so its... not terresterial!

If you have trouble remembering the order, try memorizing this:

Answer:

In genetics, dominant and recessive refer to the two different versions, or alleles, of a gene. A dominant allele is one that is always expressed, or "seen," in an organism's physical traits. A recessive allele is one that is only expressed when two copies of the allele are present in an organism. This means that if an organism has one dominant and one recessive allele for a particular trait, the dominant allele will mask the expression of the recessive allele.

Explanation:

Answer:

dominant is the gene that is likely to be present for exmaple brown eyes and blue eyes, brown eyes would be the dominant gene because it's more common while blue eyes would be receive gene because it less likely to get it

All of the characteristics listed are true for viruses except for b) metabolism.

A virus is a non-living infectious agent that can only replicate inside the host cell. They are extremely small and can only be seen under an electron microscope. Viruses are composed of genetic material (DNA or RNA) enclosed in a protective protein coat called the capsid. They do not have the ability to replicate or survive on their own and rely on host cells to provide the necessary metabolic machinery to replicate

Viruses are ultramicroscopic in size and do not have a definite shape. Viruses also infect host cells and utilize the host's metabolic machinery for replication. Viruses lack a metabolism of their own, and are thus not considered living organisms.

In case of given scenario, 9:1:6 is the ratio of magenta- to pink-to white-flowered petunias expected in the F2 progeny. The correct answer is option c.

To determine the ratio of magenta-to pink-to white-flowered petunias in the F2 progeny, we can use the Punnett square method. First, we need to determine the genotypes of the F1 progeny. The F1 progeny will all be heterozygous at both loci (AaBb). Next, we can set up a Punnett square with the F1 progeny as the parents:

|  | AB | Ab | aB | ab |
|---|----|----|----|----|
| AB | AABB | AABb | AaBB | AaBb |
| Ab | AABb | AAbb | AaBb | Aabb |
| aB | AaBB | AaBb | aaBB | aaBb |
| ab | AaBb | Aabb | aaBb | aabb |

From the Punnett square, we can see that the F2 progeny will have the following genotypes:

- 9 AABB, AABb, AaBB, AaBb (magenta)
- 1 AAbb (pink)
- 6 Aabb, aaBb, AaBb (pink)
- 4 aabb (white)

Therefore, the ratio of magenta-to pink-to white-flowered petunias in the F2 progeny is 9:1:6. The correct answer is c.
