RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.

All of Earth's biomes considered together represent:
A. population
B. community
C. biosphere
D. ecosystem
All of Earth's biomes considered together represent biosphere.
What is a biome?A biome is an amalgamation of plants and animals with similar traits for their habitat. Biomes can be found in many different locations. They are biological communities that have developed as a result of the area's common physical climate.
What is a biosphere?The biosphere is a small area of the earth's surface where soil, water, and air work together to support life. Only in this region is life possible.
What is a population?A population is a collection of people who can interbreed, share resources, or compete with one another for those resources.
What is a community?A community is defined as a collection of individuals belonging to various species who reside in the same region.
What is an ecosystem?An ecosystem is a biotic and abiotic component-based functioning unit of nature. Air, water, and soil are examples of abiotic components. The biotic components are producers, consumers, and decomposers.

Answer:
it sghwbdhfbwahdfk
Explanation:
Answer:
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Match each graph with its correlation coefficient.
+1.0
+0.85
+0.15
-0.50
-1.0
Answer:
-0.50
Explanation:
For the graph displayed, the most probable value of the correlation Coefficient is - 0.50 ; the line of best fit has a negative skoe and hence will have a negative relationship as the correlation Coefficient is a statistical value which measures the degree of relationship between two variables. Also, the distribution of data in the plot does not give a perfect fit, hence a correlation Coefficient of - 1.0 isn't possible for the distribution shown.
Answer:
fist graph: -0.50
second graph: +0.85
third graph: +0.15

Which of the following mechanisms is the correct sequence of events that takes place during the plant responses to internal and external signals?
A) transduction, reception, and response
B) reception and transduction
C) reception, transduction, and response
D) reception and response
Answer:
C) reception, transduction, and response

Plant signaling means that information is conveyed from receptor systems to effectors within and between plant cells.
Signals can be of chemical form or electrical form.
Plant responses to internal and external signals take place in the following sequence:
Reception
Transduction
Response

Alice wanted to see if a new premium gasoline would give her more kilometres per litre. She filled her car with the new gasoline and went on a long trip. When she calculated her mileage, she discovered that she has gone 40 kilometres further on this tank of gas than she went on a tank of regular gas when she was driving around town as usual. She decided to buy the premium gas from then on to get better mileage. What are the errors in this experiment?
Answer:
She didn't cover the same distance for the new premium gasoline and regular gas

The pH of a solution is a measure of how acidic or basic it is. The greater the pH, the more basic the solution is. Corals and other marine invertebrates require less energy to make their exoskeletons and shells when ocean water is slightly basic. As carbon dioxide concentrations in Earth’s atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. This process is called ocean acidification. How do you think ocean acidification will affect the coral reef?
Explanation:
Because coral reefs have limestone (calcium carbonate), the coral reefs will be greatly affected. The increase in hydrogen ions in the ocean will corrode the coral reef, making it inhabitable for species. This will affect the crabs that get their food and the community that lives within in it. Making countless of species to loose their lives and their way if living.

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?
Answer:
The genotype of the father: Ff
The genotype of the mother: ff
The genotype of the two children without freckles: ff
The genotype of the two children with freckles: Ff
Explanation:
Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles. Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype. In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.
A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
What is the significance of the freckle trait?There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).
Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
