Explanation:
So the negatively charged part of a atom is the electron cloud so A is wrong because it would be in the wrong spot. Plus the nucleus is positively charged because it contaims only protons ans neutrons. Neutrons are neutral and protons are positive so the protons over power the nuetrons. Therefore the nucleus is not made of neutrons and electrons so C is wrong. And B is also wromg because the nucleus does indeed have mass. So the correct answer is D, it is the most massibe part of a atom.

If you are looking at an object that measures 0.5 mm and the image you see is 10 mm long. Your friend is looking at an object that is 0.1 mm long using the same magnification. What is the size of image does your friend see?
The size of the image seen by a friend has been 2 mm.
What is magnification?Magnification can be given as the process of enlarging the image to a degree unlike the physical and the apparent size. The use of magnification glass has been forming the enlargement of the images or objects.
The magnification can be given as:
m = v/u
Where, m = magnification, v = object height, and u = image height
The size of the object (v) = 0.5 mm
The size of the image seen (u) = 10 mm
The magnification (m) of the image seen by a person has been:
m = 0.5 mm / 10 mm
m = 0.05
The image seen by a friend of the object (u) of 0.1 mm with a magnification (m) of 0.05 is:
0.05 = 0.1 mm/ u
u = 0.1 mm/0.05
u = 2 mm
Thus, the size of the image seen by a friend with the magnification same as the person has been 2 mm.

Explanation:
isolation occurs when two species occupy different habitats within the same geographical range.
Question:
_____ isolation occurs when two species occupy different habitats within the same geographical range.
Answer:
Habitat
Explanation:
Habitat isolation occurs when individuals in two populations are separated geographically. For example by a river or a mountain range. These organisms are much less likely to interact with each other and attempt to reproduce.
Habitat isolation is a barrier to gene flow (mixing of genes in two populations) and is a mechanism of speciation.

E. What happens to the distance between the particles of a gas when it is cooled?
(Temperature is the average speed of the particles of the gas)
F. What happens to the speed of the particles when a gas is cooled?
Plzzz help it's due today ik I'm dumb but please help me
Answer:
a. As a container of confined gas is heated, its molecules increase in kinetic energy and push the movable piston outward, resulting in an increase in volume.
B. When you heat them,you essentially give them kinetic energy which increases their speed and hence the distance between molecules increases implying that interatomic forces decreases,leading to change in state from solid to liquid
C. When the gas is heated the particles gain kinetic energy which makes them move faster. This means they collide with the walls more frequently and with greater force and so the pressure increases.
D. Both the increase in pressure and the decrease in temperature cause the volume of the gas sample to decrease. Since both changes are relatively small, the volume does not decrease dramatically.
E. When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
F. Cooling slows the velocities of the He atoms, causing them to behave as though they were heavier. 6. Both the temperature and the volume are doubled for this gas (n constant), so P remains constant. (a) The number of collisions per unit area of the container wall is constant.

Describe the differences and similarities between mitosis and binary fission.
Answer:
Binary fission is a method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning. Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.

Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.
What is mitosis?Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
The chromosomes are separated by a structure called the mitotic spindle. A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones.
These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation. Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
Therefore, Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.

First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce ATP to be used in the Calvin cycle. ATP as an energy source for the roots of the plant. sugars for the green leaf’s cellular respiration at night. sugars as an energy source for the roots of the plant. sugars to fuel the growth of the plant.
Answer:ATP as an energy source for the roots of the plant.
Explanation:
Photosynthesis is the process by which plants manufacture their own food. It involves the combination of water and carbon dioxide in the presence of sunlight. Sugars are produced in the process.
The ATP molecules produced during photosynthesis are not transported to plant root cells. Rather, metabolic activities within the plant root cells produces the energy molecules required by the plant roots.
what are the importance of planting and propagating trees and fruit bearing trees?
Answer:
Planting and propagating trees and fruit bearing trees are important because without these we won't have fruits to eat, our land will suffer from soil erosion, there will be landslide and flooding and we won't have fresh air to breathe.
Planting and propagating trees and fruit-bearing trees is important in a variety of ways:
Many fruits from trees serve as food for other organisms, including man. Fruits are rich in important nutrients that are essential for the health and survival of man.Trees are sources of timber for various construction works for man. Trees serve as habitats for other living organisms like insects, birds, etc. These organisms serve important ecological functions in the ecosystem.Trees are important for tackling water erosion. The roots of trees hold the soil structures together while their leaves reduce the force with which raindrops hit the ground.Trees help with carbon fixation. Thus, they help rid the environment of pollution and purify the air.Branches of trees also act as breakages during wind, thus, protecting the environment.More on the functions of trees in the environment can be found here: https://brainly.com/question/23108922

Why do you think catalase has to work so quickly?
Answer:
Hydrogen peroxide is toxic.
Explanation:
Hydrogen peroxide is a natural product of the reactions in the cell. However, it is toxic to cells and has to be broken down.
Catalase catalyses the breakdown of hydrogen peroxide into water and oxygen. It is found in all living cells and is very important to prevent the build up of hydrogen peroxide. If catalase didn't work quickly, hydrogen peroxide would accumulate in the cell and poison it, causing the cell to die.

Which of the following is an example of federalism?
In most cases, mutations in the core of a protein that replace a smaller nonpolar side chain in the wild-type (e.g., Ala, Val) with a larger nonpolar side chain (e.g., Leu, Ile, Phe, Trp) in the mutant, result in significant destabilization and misfolding of the mutant. What feature of the protein core explains this observation? Why would such a mutation prevent a protein from folding properly? Match the items in the left column to the appropriate blanks in the sentences on the right.
Explanation:
we are required to fill in the blank spaces in the attachment.
protein side chains are non polar. so the first answer is non polar. These side chains are hydrophobic in nature. so the second blank is hydrophobic. Non polar substances are known to have large number of van der waal forces. the third answer is large and the fourth is vanderwaals contact. the protein core destabilizes only when there is a weakening of vanderwaals contact which brings about mutation.
dear user your answer should look like this:
Interactions of non polar side chains in protein sequence lead to the formation of a tightly packed hydrophobic core. This core is stabilized by a large number of vanderwaals contact. When a mutation occurs, it destabilizes the protein core and weakens vanderwaals contact leading to misfolding
