The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).

In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.

This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

I hope this helps.

Supernova is the series of words given below, which of the following words is not categorized with the others.

A star that has reached the end of its life and bursts in a bright flash of light is what is known as a supernova.

Supernovae have the ability to briefly outshine entire galaxies and emit more energy in a single second than the sun does in its entire lifetime. Additionally, they are the universe's main supplier of heavy materials. Supernovae are "the greatest explosion that occurs in space," according to NASA.

Supernovae were noted by numerous cultures before the telescope was created in the 17th century. According to NASA's records, this "guest star" was visible in the sky for eight months.

Therefore, Supernova is the series of words given below, which of the following words is not categorized with the others.

In September the earth will be experiencing  an equinox

Equinoxes occur between March and September. When the Sun's rays strike the equator at midday and at a 90° angle, it is considered an equinox.  It stands for the idea that day and night have equivalent lengths. The sunset and dawn are separated by 12 hours everywhere on Earth. One may observe how quickly the sunset and dawn hours shift throughout the day the farther one goes from the equator.

Whereas, solstices occur in June and December. The contrary is visible close to the solstices. For a few days, both the sunset and sunrise appear to be constant. Over the course of the year, the time of day when the sun is directly overhead where one lives also gradually changes.

The natural selection is the process that organisms in the same environment pass to adapt and survive, being the individuals in a population naturally variable, with some having better adaptive traits to survive in the environment than others. The population of mice that arrived on the island with abundant resources will also go through natural selection, being the correct alternative is the one that says: " yes, because natural selection always acts on populations", since it is a natural process that occurs with all the living organisms, regardless of the circumstances.

Explanation:

The fact that the soil did not change significantly after five years, while the tree gained 74 kg, suggests that the tree's mass did not come from the soil alone. If the tree had gained all its mass from the soil, the soil would have lost an equivalent amount of mass, which did not occur. Therefore, this evidence suggests that the mass of a tree does not come solely from the soil.

While sunlight is necessary for photosynthesis, which allows the tree to produce glucose, the mass of a tree does not come directly from sunlight. Rather, the tree uses the glucose produced during photosynthesis to build its own tissues, such as leaves, branches, and roots. Therefore, while sunlight is necessary for the tree to grow, it is not the source of the tree's mass.

The tree's increase in mass is primarily due to the process of photosynthesis. During photosynthesis, the tree uses energy from sunlight to convert carbon dioxide and water into glucose, which it then uses to build new tissues. Additionally, the tree may have also taken up nutrients, such as nitrogen and phosphorus, from the soil, which it incorporated into its tissues. However, it's important to note that the majority of the tree's mass comes from the carbon that it takes up during photosynthesis, rather than the nutrients in the soil.

The advantage asexually-reproducing organisms have over sexually-

reproducing organisms is consistency of DNA to successive generations

that are identical to the parent organism.

Sexually-reproducing organisms involve the use of the sex cells from the

parent cells. Sex cells include sperm and egg cells which are donated by

both parents for reproduction and to ensure unique daughter cells are

produced.

The asexually-reproducing organisms involve only one parent which

produces an identical copy of itself thereby generating a consistent DNA to

generations which are identical to the parent organism.

Answer:

1- Presence of phenotypic variation

2- some phenotypic variation due to genetic variation

3- the given trait has an impact on fitness  

Explanation:

The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.

The correct pathway of blood through the body, including the lungs, is heart----> aorta----> body----> vena cava----> heart----> pulmonary arteries----> lungs----> pulmonary veins----> heart.

It is the circulation of blood throughout the body.

The two types are:

Pulmonary circulation starts with deoxygenated blood from the right ventricle where, through pulmonary arteries, it reaches the lungs (oxygenation of blood occurs), then through pulmonary veins, blood enters the heart in the left atrium.

Systemic circulation starts with oxygenated blood from the left ventricle, from where, through the aorta, it is pumped to the body, then to the superior or inferior vena cava, and then blood reenters the heart in the right atrium.

Hence, the correct answer is option b): heart--> aorta--> body--> vena cava--> heart--> pulmonary arteries--> lungs--> pulmonary veins--> heart.

Option b is Correct. The fact that filaments serve as tracks for molecular motors is what the next sentence refers to as a characteristic of intermediate filaments, microtubules, and F-actin.

Similar to actin filaments, microtubules are dynamic structures that can quickly expand and contract by the addition or subtraction of tubulin proteins. Microtubules exhibit directionality, which means they have two structurally distinct ends, making them similar to actin filaments in this regard.

For mobility and stability, this structure serves as a skeleton and muscle at the same time. The cytoskeleton's long fibers are polymers of subunits. The cytoskeleton is made up primarily of intermediate filaments, microfilaments, and microtubules. Actin filaments and microtubules are constructed of compact and globular actin subunits, whereas intermediate filaments are composed of smaller, elongated, and fibrous subunits.
