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.

Saponification Select one: a. is a hydrolysis reaction. b. results in the production of triglycerides. c. is used to store energy for later use. d. is a reaction found in plant metabolism.
Answer:
A) hydrolysis reaction
Explanation:
hydrolysis can be explained as a chemical process whereby molecules of water is been added to a substance, and in most reaction the substance and the water molecules split to two part as a result of the addition, and there would be gaining bof hydrogen ion by fragment of the parent molecule. An example of this is saponification.
Saponification can be defined as process of converting oil fat as well as lipid to soap and alcohol through heating using aqueous alkali. Common aqueous alkali that can be used is NaOH. Soap are regarded as salt of fatty acid. Reaction between Ethanoic acid and alcohols is an example of a saponification
Here is soap chemical formula
CH3(CH2)14COO− Na+
Answer: The correct option is A ( is a hydrolysis reaction).
Explanation:
Saponification is the alkaline hydrolysis ( using sodium hydroxide or potassium hydroxide) of fats and oil. It is commonly used for making of soaps which are used for washing and cleaning.
The process is a hydrolysis reaction because there is splitting of ester linkage bonds of triglycerides and addition of hydroxyl group from a hydroxide. This process leads to the production of alkaline salts of long chain fatty acids(soaps). This can be summarised below
Triglycerides (fats&oil) + base( NaOH)
-------> Soap + Alcohol

which term names part of the peripheral nerves system A spinal cord B brain C sensors
Answer:
[tex]\boxed {\boxed {\sf C. \ Sensors}}[/tex]
Explanation:
There are two divisions of the nervous system: the central and peripheral.
The central nervous system (CNS) is made up of the brain and spinal cord. This section processes information gathered from the sensory organs.
The peripheral nervous system (PNS) is divided into the autonomic and somatic, with different functions. Regardless of the subdivision, the PNS is made up of all the nerves and sensory receptors. The nerves are connected to the brain and spinal cord, which allows them to pass information from the PNS (where it is gathered ) to the CNS (where it is processed).
So, the spinal cord (choice A) and brain (choice B) are parts of the central nervous system, not peripheral. The correct answer must be C. sensors
Answer:
C) Sensors

Write your question here (Keep it simple and clear to get the best answer) what name iz give to the female part of the flower?
Answer:
The female part of the flower is called gynoecium or pistil
Explanation:
The female part of a flower is called the gynoecium or pistil. The pistil is located in the center of the flower and consists of three parts: the stigma, style, and ovary.
The stigma is a sticky knob-like structure located at the top of the pistil. It is covered with a sticky substance so pollen grains will stick to it. It is attached to the long, tubelike structure called the style.
The style is a long long tubelike structure which connects the stigma to the ovary. The style provides the pathway through which the pollen grains will travel to the ovary in order to fertilize the eggs or ovule
The ovary is the enlarged portion of the pistil found at the base of the pistil. It contains the eggs or ovules. After fertilization, the ovary develops into the fruit and the ovules become seeds. Based on where the ovary of a plant is located, a plant can be classified as having a superior ovary, an inferior ovary or a half-inferior ovary.
What's the answer to this?

What kind of things dissolve well in water and mean "love water"?
The condition of ketoacidosis is Select one: a. a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH. b. due to a lowered production of ketone bodies than is normal. c. the increase in pH of the cells due to ketone body production. d. only found when anaerobic catabolism of fat occurs.
Answer:
The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)
Explanation:
Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.
Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease common with ketoacidosis is Diabetes.
Morphological distinction is one of the steps necessary for speciation to occur.
What are the other two?
Answer:
Genetic Separation / Geographic isolation
Explanation:
Morphological distinction (or phenotypic differentiation) can be defined as the diversification of a set of observable physical characteristics in a population, capable of differentiating certain species.
The genetic separation occurs when the division of a group of genes into two or more pools of genes separated over time and depending on several other situational factors.
Geographic isolation occurs due to the physical separation of subpopulations of a given species. The barriers that isolate these subpopulations can be, for example, a river that cuts through a plain, a valley that divides plateaus or a portion of the sea that separates islands and continents.

What would be a probable explanation for why there are many endemic plants and birds in New Zealand, but no native mammals?
Answer:
Due to isolated before mammals evolve.
Explanation:
There are many endemic plants and birds in New Zealand, but no native mammals because New Zealand is an island which isolated from Gondwana which is a supercontinent about 85 million years ago. Before mammals evolved, the New Zealand splits and go away from the Gondwana. So due to water only those mammals that can swim or fly colonized in New Zealand but not the land living mammals.
