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.

Answer:

Enzymes and substrates fit together like a lock and key since, in one enzymatic reaction, only the correct substrate (i.e., the key) binds to its corresponding enzyme (i.e. the lock).  

Explanation:

An enzyme (or catalyst) is one protein that has catalytic functions, being therefore capable of accelerating chemical reactions. The enzymes are known to control the rate of these chemical reactions (i.e., catalysis) without suffering alterations during these processes. Thus, the enzymes are proteins that catalyze chemical reactions that are not favored under normal conditions. Moreover, one enzyme may catalyze more than one chemical transformation, as well as the same reaction may be catalyzed by two or more enzymes.

B.F Skinner was most famous for his invention, books and psychologies. He used to believe that behaviour is based on the environment. While he did not especially study epigenetic effects but his theories point out that the epigenetic effect is based on behaviour.

He introduced the "skinner box experiment". In this experiment pigeons or rats are put in cages and a lever or button provides food or water to them. And as time passed the animal learned to touch the button to get food and water. Skinner argued that this type of learning is the primary mechanism by which behaviour is shaped. But in the research, it can be concluded that genes are involved in learning and memory.

Skinner's research also showed that a specific schedule can influence the strength and persistence of learned behaviour. In some cases, where the reward is not delivered every time the behaviour is exhibited) can lead to more persistent behaviour than continuous reinforcement.

Therefore, skinner did not study the epigenetic effect of his involvement in the study of human behaviour suggesting that epigenetic mechanisms can be involved in this process.

Answer:

For every gene, there may be several possible versions. Different genes carry instructions for making different proteins. If the gene copies are heterozygous, two types of protein are produced, if the gene copies are h0m0zyg0us, one type of protein is produced.

Explanation:

Every gene has several variants. Genes encode proteins. If the gene copies are heterozygous, two types of protein are produced; if they are homozygous, one type of protein is produced.

DNA, or in the case of certain viruses, RNA, is the medium in which an organism's genome is written. A gene is a section of the genome that contains the genetic instructions for making a particular protein or RNA. Codons are units of three nucleotides in a gene that each code for a specific amino acid. Genes that code for proteins are made up of these codons.

There might be multiple variants of each gene, depending on the circumstances. Instructions for the production of a variety of proteins are contained within each gene. If the gene copies are homozygous, then only one type of protein will be produced; however, if the gene copies are heterozygous, then two different types of protein will be produced.

It is expected that the algal bloom in the Loch Raven Reservoir would change by decreasing the amount of available biomass.

The direct consequence of an algal bloom is an increase in the amount of available oxygen in the aquatic system and a drastic reduction in the light that enters into this ecosystem, which reduces the amount of biomass because plants are unable to produce photosynthesis.

Therefore, we can conclude that the consequence of an algal bloom is a decrease in the biomass that supports the trophic chain in this aquatic ecosystem.

Answer:

Advantage of cell walls

It protect and support the cell .

To give difinite shape for the cell.

Having cell walls surrounding cell membranes provides several advantages to plants, including structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture.

The cell wall is a rigid structure located outside the cell membrane in plant cells. It is composed primarily of cellulose, a complex carbohydrate. Here are the advantages of having cell walls:

Structural Support: Cell walls provide mechanical support to plant cells and help maintain the overall shape and structure of the plant. They allow plants to stand upright and withstand environmental forces such as wind or gravity. The cell walls of adjacent plant cells are interconnected, forming a strong network that provides stability to the plant as a whole.

Pathogen Protection: The cell wall acts as a physical barrier against pathogens such as bacteria and fungi. It prevents the entry of pathogens into the plant cells, reducing the risk of infection. Additionally, the cell wall can contain antimicrobial compounds and other defense molecules that provide further protection against pathogens.

Water Regulation: The cell wall plays a crucial role in regulating water balance within plant cells. It helps maintain turgor pressure, which is essential for cell expansion and overall plant growth. The cell wall allows water to enter and exit the cell in a controlled manner, preventing excessive water uptake or loss.

Cell Rupture Prevention: The rigid cell wall helps prevent cell rupture or bursting when the internal pressure within the cell increases. It provides strength and stability to the cell, allowing it to withstand internal pressure changes without bursting.

Overall, the presence of cell walls in plant cells offers significant advantages in terms of structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture. These advantages contribute to the overall health, growth, and survival of plants in diverse environmental conditions.

The changes in chromosomes are as follows:

Intercalary deletions are those that arise from inside the chromosome. Deletion mutations can arise because to losses from translocation, chromosomal crossings inside a chromosomal inversion, uneven crossing over, and breaking without rejoining. Intercalary or terminal deletions are both possible.

Terminal deletions are deletions that occur at the end of a chromosome but do not include the centromere. Intercalary deletions are caused by the loss of intercalary or interstitial regions, which necessitates two chromosome breaks and reconnection of the adjacent chromosome pieces.

Gene duplication (also known as chromosomal duplication or gene amplification) is a significant method for the generation of additional genetic material throughout molecular evolution. It is defined as any duplication of a gene-containing region of DNA.

Gene duplications can occur as a result of a variety of faults in the DNA replication and repair machinery, as well as through chance capture by selfish genetic components. Ectopic recombination, retrotransposition events, aneuploidy, polyploidy, and replication slippage are all common causes of gene duplications.

Cats have evolved certain behaviors that are influenced by their natural instincts and experiences.

When a cat sees milk, it may be attracted to it because it contains nutrients that are important for its survival, and the cat may associate the presence of milk with positive experiences. This can include nursing from its mother as a kitten or catching and consuming prey that contains milk or milk products.

On the other hand, when a cat sees a stick, it may perceive it as a threat or danger, and may associate it with negative experiences, such as being hit or attacked by a predator. This can trigger the cat's natural instinct to flee or hide from potential danger, as a survival mechanism.

Overall, a cat's behavior is influenced by its instincts, past experiences, and environmental cues. It may approach things that it perceives as positive or beneficial, and avoid or flee from things that it perceives as dangerous or threatening.
