Answer:

(A) True

Explanation:

The sun is producting the electromagnetic radiation which is the primary energy source on Earth and the driver of the entire climate system.

In general the sun is the source of energy that drives all life on Earth. This energy governs the weather, ocean currents and the hydrological cycles.

Without the continuous influx of sunlight and heat, life on Earth would cease to exist. The sun sets off the hydrological cycle, causing it to constantly evaporate into the atmosphere, from which it falls back to Earth.

Which phase of mitosis is shown in the diagram
Lorico [155]

If there's this picture in the question, the right answer is metaphase.

A metaphase qualifies a phase of meiosis or mitosis (following prophase and preceding anaphase) during which chromosomes, or at least kinetochores, align with the equatorial plate of the spindle. At this stage, chromosomes are at their maximum condensation and karyotypes are usually established. In the first division of meiosis, the metaphase represents the phase during which meiotic analysis is usually accomplished.

The crispr system involves the cas9 enzyme, which identifies specific nucleotides to be cut using a(n) ________ molecule as a gu
bonufazy [111]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally <u>bacteria and many other prokaryotes</u> have <u>CRISPR system in their genome</u> which they use as a<u> self defense against a pathogen</u> which is invading them. It consists of<u> inter spaced, short palindromic nucleotide repeats </u>which <u>encode a guide RNA (gRNA)</u>. This guide RNA (gRNA) recognizes the<u> target sequence</u> on the pathogen. The <u>gRNA is followed by Cas9 enzyme</u> which along with the gRNA plays a very important <u>role in breaking genome</u> of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by<u> non homologous end joining. </u>

But nowadays, scientists are using this system for <u>genome editing</u> and <u>incorporating desired gene</u> between the two ends which are cut down by <u>CRISPR Cas9 system.</u>

Which is an SI derived unit measurement?<br><br>0.56 kg<br>01.10 m<br>2730K<br>02.5 N​
balandron [24]

Answer:

02.5 N​

Explanation:

02.5 N​ is a derived unit of measurement.

A derived unit is one that is obtained by combining two or more fundamental units.

                    Force = mass x acceleration

                The unit of mass = kg

                                   acceleration = m/s²

Combining the two;          kg x m/s²  = kgms²

          1N = 1  kgms²

kg, m, k and N are fundamental particles
