(in orbit by the Sun's.
fa. Gravity
16 Spring force
I. Friction
d. Tension
Answer:
Gravity
Explanation:
Gravity keeps the planets, comets and meteors in orbit around the sun. The sun is bigger and heavier than other planets etc, this causes the planets to be pulled and kept in orbit around the sun.

Plants use chlorophyll during photosynthesis to absorb ------------
choices
A. sugar
B. light
C. water
Answer:
B. Light
Explanation:
In addition to giving plants their green color, chlorophyll is vital for photosynthesis as it helps to channel the energy of sunlight into chemical energy. With photosynthesis, chlorophyll absorbs energy and then transforms water and carbon dioxide into oxygen and carbohydrates.

How many categories are there on the Modified Mercalli Scale?
Answer:
i hope this helps!!?
Explanation:
Giuseppe Mercalli (1850-1914) originally developed the scale, with ten levels. In 1902, Adolfo Cancani extended the scale to include twelve levels. August Heinrich Sieberg completely rewrote the scale. For this reason, the scale is sometimes named Mercalli-Cancani-Sieberg scale, or MCS scale.

How does cytokinesis in animal cells differ from cytokinesis in plant cells?
Answer:
Cytokinesis occurs differently in animal and plant cells. In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. In plant cells, a cell plate forms along the equator of the parent cell.

What happens to the size of plants during sucession?
they get bigger
they get smaller
there is no change in siz
how dose wind cause surface currents
Answer:
Suface currents are mostly caused by the wind because it creates friction as it moves over the water. This friction then forces the water to move in a spiral pattern, creating gyres. In the northern hemisphere, gyres move clockwise; while in the southern hemisphere, they spin counterclockwise.

do boys lose the ability to scream after puberty ? not shout scream
Answer:
weird question but I don't think so-
Answer:
No, They do not.
Explanation
As you get older, your larynx grows and your vocal cords lengthen and thicken, resulting in a deeper voice. Your voice can "crack" or "break" as your body adjusts to the new equipment. However, this procedure only takes a few months, it does not affect a boys ability to scream.

Answer: B
Explanation:
Do you believe your house would be prepared in the event of a tsunami? Why or why not?
Answer:
Yes because we don’t live by an ocean
Explanation:
Answer:
Just say no. If there is a tsunami, the average modern day house would be flooded and sustain significant structural damage. It would not be able to withstand the crushing forces of the water unless it is specially built. Assuming that you don't live in an area where tsunamis are likely, your house was not built that way.
Explanation:
Definition: This is is a medical procedure used in prenatal diagnosis of chromosomal abnormalities in
which a small amount of amniotic fluid is extracted amniotic sac surrounding a developing fetus and the
fetal DNA is examined.
Answer:
Amniocentesis
Explanation:
It involves inserting a long needle to extract fetal cells from the fetus's surrounding fluid for these diagnostic purposes. It is a risky procedure that has since been widely replaced by cell-free DNA testing.

Explanation:
(b) Describe the characteristics of the interior of the aquaporin channel protein that allow water to flow through AND exclude glucose.
If isolated keratinocytes are placed in a hypotonic solution for 24 hours, explain the net direction of water movement AND why the
rate of water movement slows down over time.
Answer:
Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices.
Explanation:
Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices. These aquaporin protein have different size of water channels that allow water through to pass through it but it does not allow glucose to move through it due to its large size. The direction of water movement is toward the cell because there is low water inside the cell as compared to outside environment so the water moves inside the cell and rate of water movement slows down over time due to filling of empty spaces with water.
Helppp it’s really important
Answer:
option (a) because....,
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). ... Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA)
option (b) not because,
Within that centrosome there are two centrioles. And centrioles are physical objects made up of things called microtubules.
option (c) not because....,
Centromere repeats in humans are made up of alpha-satellite DNA, a ∼171 bp sequence or monomer that is iteratively repeated. Alpha-satellite monomers are arranged head-to-tail and organized into repeated arrays called higher order repeats (HORs) that range from 0.2 to 5 megabases (Mb) and are chromosome specific.

3'-GTGCACCTGACT-5'
Which sequence of mRNA is the correct transcription of this DNA?
Answer:
The correct answer is - 5' CACGUGGACUGA 3'
Explanation:
Transcription is one of the important processes in protein synthesis that involves encoding the genetic information of DNA into an mRNA molecule that takes it to the ribosome and translates it to amino acids.
The transcription from DNA to mRNA occurs in a complementary manner for the nitrogenous base which means adenine converts to uracil and thymine converts to adenine similarly guanine and cytosine convert in each other.
Thus, 3'-GTGCACCTGACT-5' will be translated as:
5' CACGUGGACUGA 3'

where does the pollen go
Answer:
To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

your name is Usain or Cathy Freeman of sunny vale college,suncity your school had interhouse competition for one day at BNZ stadium
Answer:
12th February, 2021 10:30 p.m.
Friday
Dear Diary,
Today I'm very happy as I had won many events in the interhouse competition which was held today in BNZ Stadium.
So, in which I was also selected and our school named Sunny Vale College, Suncity held this interhouse competition in the BNZ Stadium. There were many events such as disc throw, javelin throw, 100 meters sprint, and many more. I had participated in many of the events. I also got the 1st position in 100 meters sprint, shot foot , disc throw and high jump. At last when the event was going to end there was also a wonderful event that was relay race. I had been selected for this group relay and at last our group won the relay race.
It was a very lucky day for me, on this wonderful day of the events held by our school.
Usain .
