The slight attractions that develop between oppositely charged regions of nearby molecules are called ______
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.

Why is the global change model important ? What does it tell us?
Answer: Climate models are important tools for improving our understanding and predictability of climate behavior on seasonal, annual, decadal, and centennial time scales. Models investigate the degree to which observed climate changes may be due to natural variability, human activity, or a combination of both.

:) 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
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.

Which part of our immune system takes
longer to respond but acts quicker the next
time the same pathogen attacks us?
Innate immune response
Acquire immune response
Answer:
The adaptive immune response is a slower-acting, longer-lasting, and more specific response than the innate response. However, the adaptive response requires information from the innate immune system to function. APCs display antigens via MHC molecules to complementary naïve T cells.

If the Earth's axis is tilted towards the Sun, what are those places on Earth experiencing?
It'd help if you could answer, because I don't speak Google.
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.

Butter is a fat that is a solid at room temperature. What type of fatty acids does butter contain? If you studied its molecular structure what would you se tht is different from fats that are liquid at room temperature
Answer:
saturated fatty acids
Explanation:
Butter is a fat that is solid at room temperature because it is a saturated fatty acid and contains 70 percent of It. Butter comes from a cow, which is an animal source.
Fats that are liquid at room temperature are unsaturated fatty acids. The molecular structure of saturated fatty acid and unsaturated fatty acid are different as saturated fatty acids lack double bonds while unsaturated fatty acids consist of at least one double bond. saturated fatty acids are linear and unbranched while unsaturated fatty acids are branched.
Hence, butter contains saturated fatty acids.

Describe the process of asexual reproduction in the following I)Amoeba 2) Rhizopus 3)yeast 4)spirogyra
Answer:
1)Amoeba reproduces by the common asexual reproduction method called binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal sized daughter cells. ... In this process, the nucleus of the Amoeba first divides to form two daughter nuclei by the process of Karyokinesis.
2)Rhizopus is the species of a fungus. They reproduce asexually by the formation of the spores. ... The sporangium is a swollen structure at the tip of the filaments bearing the spores. The spores are tough and resistant structures which are dispersed by the breaking of the sporangium.
3)Budding in Yeast .Most yeasts reproduce asexually by an asymmetric division process called budding. First it produces a small protuberance on the parent cell that grows to a full size and forms a bud. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell.
4)Spirogyra species can reproduce both sexually and asexually. Asexual, or vegetative, reproduction occurs by simple fragmentation of the filaments. Sexual reproduction occurs by a process known as conjugation, in which cells of two filaments lying side by side are joined by outgrowths called conjugation tubes.

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?
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.
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.
