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.

Senescence __________. Question 5 options: a) begins at the moment of conception and accelerates after age 40 b) occurs across all parts of the body at the same time and speed c) begins once body structures reach maximum capacity and efficiency d) occurs because the physical body wears out from use
Answer: c. Senescence begins once body structures reach maximum capacity and efficiency
Explanation: Senescence is simply ‘growing old’. Aging sets in at the time when physical development is complete - when a person reaches their ‘prime’. After that a person is ‘past their prime’ which is the subjective recognition of the on set of gradual deterioration. The biological rationale is that the purpose of life is to survive to reproductive age and to reproduce, and in some species to assist progeny to survive to reproductive age. Beyond that, survival has limited value.
An analogy is the length of an elephant’s trunk. It is as long as it needs to be, determined by natural selection, but no longer than it needs to be for optimum efficiency, again determined by natural selection.

The Calvin cycle is the light-dependent stage of photosynthesis and occurs in the stroma. The Calvin cycle is the light-dependent stage of photosynthesis and occurs in the thylakoid membrane. The Calvin cycle is the light-independent stage of photosynthesis and occurs in the stroma.
The true statement about calvin cycle is "The Calvin cycle is the light-independent stage of photosynthesis and it occurs in the stroma"
Photosynthesis is generally the process whereby cells of autotrophic organisms obtain their food in form of sugars in the presence of sunlight. The photosynthetic process occurs in two stages namely: light dependent and light independent stage. The light dependent stage is the first stage, which occurs in the thylakoid membrane of the chloroplast. In this stage, ATP and NADPH is produced for the second stage.LIGHT INDEPENDENT STAGE is also known as CALVIN CYCLE. It is so called because it does not need light to occur. This stage occurs in the STROMA, where the glucose is synthesized.Therefore, the true statement about calvin cycle is "The Calvin cycle is the light-independent stage of photosynthesis and it occurs in the stroma"Learn more at: https://brainly.com/question/17600594?referrer=searchResults

Answer:
D (but b on the map)
Explanation:
A. The sun heats the air at the equator, followed by hot air rising and moisture condensing
B. Air moves towards the poles as it cools
C. The dry air moves back to the equator, picking up a lot of moisture on the way
D. The air sinks around 30° latitude and is very dry.
Answer:
B. Air moves towards the poles as it cools
Explanation:
The image represent convection cell or Hadley cell is a natural phenomenon in the atmosphere that occur due to difference in the density within a body of liquid or gas. These differences in density causes rise and fall in currents.
The process in step A refers to when hot air moves up and in the step B, the hot air encounters a cold surface, it direct exchange the heat with cold surface and the air cools down and move towards the poles.
Hence, the correct answer is "B. Air moves towards the poles as it cools".

Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth. The ocean's tidal energy causes water to cycle on the earth. The water from the oceans evaporate and form precipitation. The precipitation then condenses back on the surface of the earth. The earth's magnetic energy causes water to evaporate. The water condenses into water vapor once it becomes precipitation. The condensation then falls back to the surface of the earth. The sun's thermal energy causes water vapor to condense. This condensation then forms precipitation. This precipitation returns to the atmosphere for the cycle to continue.
Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth.
Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.
The ocean's tidal energy does not cause water to cycle on earth.
