Cell differentiation is the process by which cells specialize to achieve their required functions. In order for a cell to differentiate, it will express specific genes. ... Importantly, mitosis produces cells that are identical to each other (clones).

Among the newly-discovered small noncoding RNAs, one type reestablishes methylation patterns during gamete formation and blocks expression of some transposons. What are these types of RNA called
Answer:
piwi-interacting RNAs (piwi-RNAs)
Explanation:
The piwi-interacting RNAs (piRNAs) are small non-coding RNAs (from 21 to 31 nucleotides) that are abundantly expressed in the animal germline in order to control the expression of target sequences. The piRNAs associate with PIWI proteins from the Argonaute family (AGO) to form an effector complex that binds to complementary target DNA/RNA sequences. These small ncRNAs target Transposable Element (TE) transcripts to suppress TE expression and thus maintain genome integrity. The piRNAs can also guide epigenetic remodeling complexes that suppress gene expression by methylation of target DNA sequences in the nucleus.
Which process is true about natural selection?

Explanation:
All cells contain two proteins called actin and myosin? True or false
Answer: i think its true
Explanation:
True that all eukaryotic cell i.e. muscle cells. contains actin and myosin protein .
What are actin and myosin protein?Actin filaments are responsible for a variety of cell motions, generally in conjunction with myosin. Myosin is a molecular motor prototype—a protein that transfers chemical energy in the form of ATP into mechanical energy, allowing it to generate force and movement. Muscle contraction is the most noticeable type of such movement, and it has served as a model for studying actin-myosin interactions and myosin motor activity. Actin and myosin interactions, on the other hand, are essential for not just muscle contraction but also a range of non muscle cell motions, including cell division, making them important in cell biology.Actin is a protein found in all eukaryotic cells. Actin filaments move along filaments of another protein called myosin to cause cells to contract. It was initially found in skeletal muscle. Actin filaments are less structured in non muscle cells, and myosin is considerably less prominent.Hence, the given statement is true.

Which statement correctly defines wind? MARKING BRAINLIEST!
Answer:
C
Explanation:
A cannot be correct because particles will move from areas with higher pressures to lower pressures.
D also accnot be right becuase air does not simply bounce of off earth surface.
B also does not make sense because air partices will not want to move to a "cooler" area.
C Air particles do move from areas of high pressure to areas of low pressure. So, c is the correct answer.

In general, how do sensory systems function?
Answer:
Sensory nervous system detects and encodes stimuli and then sends signals from receptors. (evidence below for a clearer answer)
Explanation:
"As a whole, the sensory nervous system detects and encodes stimuli and then sends signals from receptors, that is, sense organs or simple sensory nerve endings, to the central nervous system, that is, it transduces environmental signals into electrical signals that are propagated along nerve fibers."

During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this
Answer:
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Explanation:
We know that water expands anomalously. It expands between 4- 0°C.
Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Some tools contain permanent magnets. What two types of materials could these tools pick up?
A. Materials that contain a magnetic material, such as iron
B. Materials that contain glue or other adhesives
C. Materials that contain other magnets
D. Materials that contain a ceramic, such as glass
Permanent magnets are the objects producing the invisible magnetic field. The tools containing the permanent magnets will pick the magnets and iron. Thus, options A and C are correct.
What are permanent magnets?Permanent magnets are the magnetic field-producing materials that pull or repel the ferromagnetic materials towards or away from themselves. The magnetic field is produced from the internal magnetic material.
They are formed when the ferromagnetic objects are heated at high temperatures and have those properties for a very long time. These magnets can attract objects that have magnetic fields around them like iron and other magnets.
Therefore, a permanent magnet will attract magnets and magnetic materials like iron.

Explain how the farms upriver were adding to the high nitrate levels. gizmo
Answer:
Farmers were adding high nitrate levels from many large corn farms along the river. The farmers spray fertilizers that have ammonia and nitrate onto their crops. During the drought, the farmers used extra fertilizer. As rained, the ammonia and nitrate from the fertilizer were washed into the river.
In the pigs produced 10 pounds of feces that contained ammonia and nitrate. The pit is too small to obtain such large amount. When it rained the waste overflowed in to the river.
Explanation:
The drought from the week before and the large rain fall played a large part in the outcome of the annomia and nitrate exposure to water.
The farms upriver were adding to the high nitrate levels. It was because of the excessive use of fertilizers and inadequate waste disposal techniques.
What are agrochemicals?There are chemicals that are used in agriculture. It includes fertilizers, pesticides, nematicides, insecticides, etc.
How does farm upriver add nitrate?The farms upriver used to apply agrochemicals, especially the ones rich in nitrate and urea. During fewer water conditions they used to apply more. That used to remain in the soil and washed down to the river along with the rain.
The farms did not use adequate waste disposal measures and hence the wastes rich in nitrogen were washed down to the river.
Hence, these practices increase nitrate levels in the river.

O low temperature
O high concentration of enzyme
Answer:
Low temperature
Explanation:
because.
Have a great day!!!
The factor that can decrease the rate of a chemical reaction is a low temperature.
What is chemical reaction?A chemical reaction is the chemical transformation of one set of chemical substances into another.
A low temperature is one factor that can slow down a chemical reaction. A chemical reaction is defined as a process that transforms one set of chemical substances into another.
The rate of a chemical reaction is a measure of how quickly the reaction takes place.
A low temperature can slow down a chemical reaction by lowering the kinetic energy of the reacting molecules.
This means the molecules move slower and are less likely to collide with enough energy to break bonds and form new ones. As a result, the reaction rate slows down.
Thus, the answer is low temperature.
