What is the relationship between greenhouse and effect and sunlight ?
Answers
Answer:
In the daytime, sunlight shines into the greenhouse and warms the plants and air inside.
Explanation:
At nighttime, it's colder outside, but the greenhouse stays pretty warm inside. That's because the glass walls of the greenhouse trap the Sun's heat. The greenhouse effect works much the same way on Earth.

It'd help if you could answer, because I don't speak Google.
Answers
Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Hello!
✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
❖ A always goes with T (Adenine - Thymine)
G always goes with C (Guanine - Cytosine)
If the pairs aren't the way they're supposed to be, this can result in genetic disorders
~ ʜᴏᴘᴇ ᴛʜɪꜱ ʜᴇʟᴘꜱ! :) ♡
Answer:
The base pairing rules for DNA are governed by the complementary base pairs: adenine (A) with thymine (T) in an A-T pairing and cytosine (C) with guanine (G) in a C-G pairing. Thymine only binds with adenine in a T-A pairing and guanine only binds with cytosine in a G-C pairing.

The slight attractions that develop between oppositely charged regions of nearby molecules are called ______
Answers
Explanation:
They are called, " vanderwals," forces. not as strong as covalent bonds or ionic bonds, but still exist...
The slight attractions that develop between oppositely charged regions of nearby molecules are called Van der Walls force.
When they are at a moderate distance, the molecules attract each other, but when their electron clouds begin to overlap, the molecules repel each other strongly.
Van der Walls force are forces of attraction or repulsion between molecular entities different from those that are due to the electrostatic interaction of ionic groups with each other or with neutral molecules.
That is, they are slight attractive forces that are established between electrically neutral molecules (both polar and nonpolar), but they are very numerous and play a fundamental role in many biological processes.
These form a non-covalent chemical bond in which two types of forces or interactions participate, dispersion forces (which are attractive forces) and repulsion forces.
Therefore, we can conclude that the slight attractions that develop between oppositely charged regions of nearby molecules are called Van der Walls force.

In peas, axial (A) flower position is dominant to terminal (a), and tall (L) is dominant to short (l). If a plant that is heterozygous for both traits is allowed to self-fertilize, how many of the offspring would also be heterozygous for both traits?
Answers
Answer:
The correct answer is - 1/4 or 25%.
Explanation:
The parents have a heterozygous condition for both trait flower position and height of the pea plant. The representation of allele would be AaLl for both parents and each parent produce the same gametes that would be AL, Al, aL, and al.
Then the Punnett square will be :
AL Al aL al
AL AALL AALl AaLL AaLl
Al AALl AAll AaLl Aall
aL AaLL AaLl aaLL aaLl
al AaLl Aall aaLl aall
Out of 16 offspring 4 have heterozygous which means:
The heterozygous condition will be = 4/16 = 1/4
Thus, the correct answer is - 1/4

Which of the following is possible due to the high surface tension of water? *
A) Lakes don't freeze solid in winter, despite low temperatures.
B) A water strider can walk across the surface of a small pond.
C) Organisms resist temperature changes, although they give off heat.
D) Water can act as a solvent.
E) The pH of water remains exactly neutral.
Answers
Answer:
B) A water strider can walk across the surface of a small pond.
Explanation:
Water striders can walk on top of the water by using the high surface tension of the water and their long, thin legs to distribute their weight over the water. Their legs also have hydrophobic hairs which help them move over the surface.
A water strider can walk across the surface of a small pond, is possible due to the high surface tension of water.
What are Water Striders?Gerridae are one of the family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, or water skimmers.
Consistent with the classification of the Gerridae as true bugs, gerrids have mouthparts evolved for piercing and sucking, and distinguish themselves by having the unusual ability to walk on water, making them pleuston (surface-living) animals.
They are built to transfer their weight to be able to run on top of the water's surface. As a result, one could likely find water striders present in any pond, river, or lake.
More than 1,700 species of gerrids have been described, 10% of them being marine.
What is Surface Tension?Surface tension in water might be good at performing tricks, such as being able to float a paper clip on its surface.
Surface tension performs many more duties that are vitally important to the environment and people.
Hence, option B is correct.

:) The Big Bang Theory, describing the creation of the universe, is most directly supported by the
O redshift of light from distant galaxies
O presence of volcanoes on Earth
O apparent shape of star constellations
O presence of craters on Earth's Moon
Answers
Answer:
A
Explanation:
Redshift is when waves on the shift to the redder side of the visible light spectrum, meaning that they are becoming stretched out. This supports the theory that galaxies are moving farther away due to the momentum of the Big Bang, supporting the theory.
Hope this helps! Good luck :)
Big Bang Theory is an explanation that determines how the universe began and expanded. The universe is still stretching and it was started all at a single point.
The correct answer is:
Option A. redshift of light from distant galaxies
The redshift can be explained as:
1. The Doppler effect or red-shift of light from faraway galaxies gives the idea that the universe is expanding and stretching.
2. This accounts for the big bang theory in which space began from a single point and all the matter is moving away from the origin.
The correct answer is Option A.
