Answer:
Dicer
RNA-dependent RNA polymerase amplifies siRNAs by binding to them and making more dsRNA, which is recognized and cleaved by Dicer into secondary siRNAs. The result is the silencing of genes by amplifying the RNAi effect. In certain cases RNAi also silences genes by the formation of heterochromatin.

Regarding cell walls, which of
these is the MOST accurate?
im
A. Cell walls and cell membranes are the very
same thing
B. Cell walls burst any time the cell takes in too
much water.
C. Cell walls keep a plant, bacteria or fungus cell
from bursting when too much water is absorbed
Answer:
C
Explanation:
cell wall
When water moves into a plant cell, the vacuole gets bigger, pushing the cell membrane against the cell wall. The force of this increases the turgor pressure within the cell making it firm or turgid . The pressure created by the cell wall stops too much water entering and prevents cell lysis.
Why is the metric system more scientific than the English system?

B. The English system is only used in English-speaking countries.
C. The English system was based on human traits, while the metric system was founded on physical constants.
D. The English system must be converted to the metric system using conversion factors.
Answer:
Unlike the British Imperial System, the metric system, or SI (from the French Système International), is based on a natural constant.
Explanation:
The metric system is more scientific than the English system because the English system was based on human traits, while the metric system was founded on physical constants.
What do you mean by the Metric system?The metric system may be defined as the scientific way of measuring weights, and distance in kilograms and meters respectively with the help of a decimal system.
The metric system may also be known as the SI system. SI system is not based on the human traits rather then it depends on the natural constant. It is more precise, standard, and easy to understand.

Draw the structure of ATP molecule and explain how it is formed
ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.
ATP molecule is formed in the process of respiration i.e. aerobic and anaerobic. During aerobic cellular respiration, glucose reacts with oxygen in the mitochondria of the cell, forming ATP that can be used by the cell in different cellular activities. When glucose reacts with oxygen, three molecules are formed i.e. ATP, Carbon dioxide and water. ATP is used by the cell whereas the Water and carbon dioxide molecules are waste materials which are removed from the cell so we can say ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.Learn more about ATP here: https://brainly.com/question/893601

PLEASE HELP WITH THIS ONE QUESTION
Answer:
Fourth option
Explanation:
ATP - Adenosine Triphosphate (3Ps), ADP - Adenosine Diphosphate (2Ps). ATP breaks down into ADP because it loses a Phosphate Anion in whatever process that the ATP is becoming ADP.
In the image provided, fourth image shows how ATP breaks down into ADP. Option D is the correct answer.
ATP (adenosine triphosphate) is a molecule that stores and provides energy for cellular processes. When ATP is used, it undergoes a process called hydrolysis, where a water molecule is used to break a high-energy phosphate bond in ATP. Option D is the correct answer.
During this hydrolysis process, one of the phosphate groups in ATP is cleaved off, resulting in the formation of ADP (adenosine diphosphate) and an inorganic phosphate (Pi). The energy stored in the phosphate bond is released, making it available for cellular functions. The breakdown of ATP into ADP allows the released energy to be utilized by cells for various activities, such as muscle contraction, active transport, and synthesis of molecules.

Answer:: De-termination could offer experiences into development and normal assets that are at present inaccessible to us.
2: Compromised or harmed biological systems could be reestablished with the assistance of specific now-wiped out species.
3 In the event that people drove plant and creatures species into termination, maybe we owe it to these species to attempt to bring them back.
4 De-elimination could be a major advance forward for hereditary designing.
There are loads of valid justifications to bring back wiped out creatures. All creatures perform significant jobs in the environments they live in, so when lost species are returned, so too are the 'positions' they once performed. Wooly mammoths, for instance, were nursery workers. ... It very well may be something similar for other de-wiped out creatures, as well.
Zeroing in on de-elimination could think twice about by redirecting assets from protecting environments and forestalling more current eradications. It could likewise diminish the ethical load of annihilation and backing for imperiled species, sending the mixed signal that resuscitating a wiped out creature or plant is trifling

How animals can be classified on the basis of the ability to thermoregulation?
a. Viruses reproduce using a ______ _____.
b. What are the differences between proviruses and viral DNA?
c. Why is the common cold virus so difficult to cure?
Answer:
Viruses reproduce using a host cell
The differentce between proviruses and viral DNA is A provirus is a virus genome that is integrated into the DNA of a host cell. In the case of bacterial viruses (bacteriophages), proviruses are often referred to as prophages. However, it is important to note that proviruses are distinctly different from prophages and these terms should not be used interchangeably.
Common cold virus is difficult to cure because Unfortunately, antibiotics — medications that treat bacterial infections — cannot treat or cure a common cold. That's because colds aren't caused by bacteria. Some people report that they've had a cold, took antibiotics, and felt better after a few days of the medication.

The amount of D N A doubles as the D N A is replicated.
The amount of D N A slightly increases as a result of new organelle synthesis.
The amount of D N A does not change while the cell grows.
The amount of DNA is halved as the cell divides into two daughter cells.
Answer:
The amount of DNA doubles as the DNA is replicated
Explanation:
on the graph it shows that the DNA is x2 by the time it reaches G2
The amount of DNA is halved as the cell divides into two daughter cells. Therefore, option (D) is correct.
What is M phase?M phase, also known as mitosis, is the phase of the cell cycle in which a cell divides into two daughter cells. M phase is divided into several stages, including prophase, prometaphase, metaphase, anaphase, and telophase. During prophase, the cell's nucleolus disappears and the chromatids (replicated chromosomes) become visible. In prometaphase, the nuclear envelope breaks down and the mitotic spindle begins to form.
During metaphase, the chromosomes line up at the equatorial plane of the cell. In anaphase, the sister chromatids are separated and move to opposite poles of the cell. Finally, in telophase, two new nuclei form and a new cell wall begins to grow between the two daughter cells. Overall, M phase is a crucial step in the cell cycle that ensures the accurate segregation of genetic material to the daughter cells.

Answer:
In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin, whereas in the tissues, where low pO2, high pCO2, high H+ concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin. This clearly indicates that oxygen gets bound to haemoglobin in the lung surface and gets dissociated at the tissues

Complete the sentence. Carbon flows between ____________, environmental storage centers that absorb and store carbon for long periods of time.
plants and animals
humans and air
rocks and soil
carbon sinks
Carbon is transfered by plants and animals.
Carbon flows between plants and animals, environmental storage centers that absorb and store carbon for long periods of time. Thus, the correct option is A.
What is Carbon cycle?Carbon cycle is one of the main biogeochemical cycles which has four main steps. In this first, carbon enters into the atmosphere as CO₂. CO₂ is absorbed by the autotrophs such as green plants for photosynthesis. Then, the animals consume plants as food, thereby, incorporating the carbon into their system. Afterwards, animals and plants die, their bodies decompose and the carbon is reabsorbed back into the atmosphere.
In this, plants use carbon dioxide for photosynthesis. Through this, they remove the inorganic carbon from the atmosphere and incorporate it into the plant's tissues in the form of sugars such as glucose, sucrose and starch. Animals get carbon by eating the plants or by hunting other animals.
Therefore, the correct option is A.
