RNA molecule acts as an adapter between mRNA and amino acids is tRNA  which is option D.

Transfer RNA (abbreviated tRNA) is a small RNA molecule that performs a key function in protein synthesis. Transfer RNA serves as a link (or adaptor) among the messenger RNA (mRNA) molecule and the developing chain of amino acids that make up a protein. t-RNA binds to the ribosomal m-RNA complicated through initiation and elongation factors, making it less complicated for the proper amino acid to be delivered to the polypeptide chain through its particular anticodon to the m-RNA codon. As a result, t-RNA is called an 'adapter.

Thus, the correct option is D is tRNA.

For places that receive a bit more rain each year and can grow short grasses, grazing herds are a suitable option.

Although many marginal, semi-arid steppe areas have been planted with crops, they are not economically viable; most of the cereals produced in these areas are fed to livestock; however, grain yields in these areas are very low and produce no more livestock products than would be produced in natural grassland, despite being much more expensive.

A wide variety of specialized crops can be supported by well-drained, loamy soils. Stone fruit and root crops cannot be grown in clay soils with a finer texture and poor drainage without significant modification. When cultivated, excessively sloped land is vulnerable to erosion and is best suited for perennial plants.

Respiration and activity are closely related in the sense that respiration is the process by which our bodies generate energy to fuel physical activity.

During respiration, our bodies break down glucose and other molecules using oxygen to produce ATP, which is the primary energy currency of the body. This ATP is then used by the muscles to perform physical activity such as walking, running, lifting weights, or any other form of movement.

The rate of respiration increases as the body's demand for energy increases during physical activity. This increased respiration rate helps to supply more oxygen to the muscles, which allows them to continue functioning and producing ATP to support the activity.

The eccentricity of the moon's orbit is approximately 0.487.

Eccentricity is a value that describes the shape of an orbit. It is a dimensionless number that ranges from 0 to 1. A value of 0 represents a circular orbit, where the distance from the center of the orbit to the object in orbit is constant. A value of 1 represents a parabolic orbit, where the object in orbit is moving at the escape velocity and will never return to the center of the orbit. Values between 0 and 1 represent elliptical orbits, where the distance from the center of the orbit to the object in orbit varies. The closer the eccentricity value is to 1, the more elongated the elliptical orbit is. Eccentricity is used to describe the orbits of planets, moons, asteroids, comets, and other celestial bodies.

The eccentricity of an orbit is a measure of how "elliptical" an orbit is, with a value of 0 representing a perfect circle and a value of 1 representing a perfect ellipse.

The formula to calculate the eccentricity of an orbit is:

e = c/a

Where:

c = distance between two foci (3.7)

a = length of the major axis (7.6)

e = 3.7 / 7.6 = 0.487

Therefore, the eccentricity of the moon's orbit is approximately 0.487.

Most radiant heat is lost through the head and upper body. Radiant heat is heat that is transmitted through radiation, rather than conduction or convection.

Radiant heat is often produced by sources such as the sun, fire, or hot surfaces, and it can be easily felt by the body when it is in close proximity to the source. The head and upper body are more susceptible to radiant heat because they are relatively exposed and have fewer layers of insulation than other parts of the body.

To reduce the loss of radiant heat, people can use protective clothing such as hats, gloves, and long-sleeved shirts. They can also try to avoid spending prolonged periods of time in direct sunlight or near heat sources, and they can use shade or ventilation to reduce the temperature in the area.

Overall, it is important to be aware of the potential for radiant heat loss and to take steps to protect yourself from it, especially in situations where you are exposed to strong sources of heat.

The evolutionary relationship between species can be determined through genetic and morphological analysis, as well as the fossil record.

In biology, a species is a basic unit of classification and a fundamental concept in the study of biodiversity. A species is defined as a group of organisms that can interbreed to produce fertile offspring. Members of a species share a common gene pool, and they are reproductively isolated from other groups. The concept of a species can be applied to both sexually reproducing and asexually reproducing organisms. In sexually reproducing organisms, interbreeding is necessary for the production of fertile offspring. In asexually reproducing organisms, a species is defined by the genetic and morphological characteristics of a group of organisms that have descended from a single common ancestor.

The strength lens needed to bring his near point to 25cm is 2.18 diopters.

The strength of a lens is determined by lens material and angle of the curve that is ground into the lens. Lens strength is expressed in diopters (D), which indicates how much the light is bent.

For a farsighted person with near point (v) = 55 cm rather than normal object distance of u = 25 cm.

Using Lens formula:

1/f= 1/u +1/v

Here, f = focal length ; v = image distance and u = object distance

As the image must be on same side of the lens, then the image distance must be negative.

Hence, 1/f= 1/25 + 1/-55

1/f= 0.0218 cm

f = 45.8 cm

So, f = 0.458m

Dioptic power is inverse of the focal length strength; D= 1/f

=1/0.458

D = 2.18 diopters.

Answer:

See the answer below

Explanation:

If a cell containing 15% salt is placed in a 55% salt solution and osmosis takes place, water molecules would move from the cytosol of the cell to the surrounding salt solution until an equilibrium concentration is established between the two solutions. The cell would lose water to the 55% salt solution and become flaccid because it has a higher water potential than the surrounding solution.

Local hormones are swiftly activated and deactivated. They are released as a result of physical activity and exercise. They primarily influence the dilation of smooth and vascular muscles. The amount of ligand and the number of receptors on the target cell determine the strength of the response ( the specific local hormone). Hormones are substances that transmit information from your blood to your organs, skin, muscles, and other tissues, allowing them to coordinate various tasks in your body. These signals instruct your body on what to do and when.

Answer:

Yes

Explanation:

This can be explained with the concept of induced resistance. it is the ability of a plant to respond the certain chemical released from the damaged body parts,The diffusion of the chemical stimulates all other plants parts and other plants to be less tasty and therefore not pleasant to eat. Thus the more the extent of damage to the plant,the higher the volume of chemicals released and therefore the less tasty the plants and lower the damages-negative feedback mechanisms. Since this restored the plants to relatively constant internal environments,this is homeostasis.

Hornworm caterpillar damages tomatoes plants leaves,leaving holes.When a tomato plant is eaten,it releases chemical substance called methyl jasmonate. The latter would be received by adjacent plants parts or other tomato plants. The receptive tomatoes plants therefore becomes less tasty. Hence the caterpillar after destroying  the initial part of the tomato plants would not be able to continue with the feeding and therefore feed on one another leading to their death,turning them to cannibal caterpillars.

Since in an attempt to maintain the relatively constant internal environment plant releases methyl jasmonate to prevent futher damage and therefore ensures stability of the plant.
