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.
Explanation:
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.

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.

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.

4. What material passes through a hole of a strainer when sieving
is used to separate mixtures?
Answer:
Explanation:
A strainer is a device that is used to remove foreign/specific "dirt" from a liquid (usually when flowing). Strainers usually have holes just like a sieve except that this time, it separates dirt (tiny solids) from the liquid unlike a sieve that separates solid particles of different sizes.
It should however be noted that sometimes the strainer is designed to remove a valuable "dirt" from the flowing liquid.
Very small particles such as fine flour particles can pass through the hole of the strainer.
Those particles which are smaller in size of the hole of the strainer can pass through it while on the other hand, large particles can pass through it. Sieving allows the fine flour particles to pass through the holes of the sieve but prevent or stops the bigger particles from entering the sieve so we can conclude that very small particles can pass through the hole of the strainer but the large particles can't.

Explanation:
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

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.

Organisms can form several types of symbiotic relationships. From the descriptions, determine if each of the symbiotic relationships is an example of commensalism, mutualism, or parasitism. 1. Hermit crabs protect themselves from predators by living in shells discarded by snails. 2. Ticks attach to humans in order to eat human blood. Ticks can also infect humans with Rocky Mountain spotted fever and Lyme's disease. 3. The coralroot orchid is a reddish color and is unable to photosynthesize. These orchids take carbohydrates from pine trees through connections formed between their roots and the roots of the pine trees. 4. The bullhorn acacia grows special tissues in which ants live. The ants find a safe place to live and attack any animals that attempt to graze on the acacia. 5. The Leucochloridium worm infects snails and is able to control the snail's behavior, creating a zombie-like snail. The worm forces the snail to attract predators to itself so that the worm is eaten and passed to its next host. 6. On the Galapagos Islands, there are finches that remove parasitic insects from tortoises. The finches gain a meal and the tortoises are ridded of parasites. 7. Cattle egrets follow cattle and other large grazing animals and eat the insects stirred up by cattle's hooves.
Answer:
From the questions, here are the answers.
1 is commensalism
2. Parasitism
3. Parasitism
4. Mutualism
5. Parasitism
6. Mutualism.
7.Commensalism
Explanation:
Hermit crabs protect themselves from predators by living in shells discarded by snails and Cattle egrets follow cattle and other large grazing animals and eat the insects stirred up by cattle's hooves relationship is commensalism because commensalism is a symbiotic relationship that take place between two organisms in which one benefits and the other is neither harmed or does not benefit. Hermit crabs benefit by receiving protection from snail shells and snail does not benefit and not harmed. Cattles eagret feed on insects on cattle hoolves, cattle is not harmed or does not benefit
Parasitism
2. Ticks attach to humans in order to eat human blood. Ticks can also infect humans with Rocky Mountain spotted fever and Lyme's disease. 3. The coralroot orchid is a reddish color and is unable to photosynthesize. These orchids take carbohydrates from pine trees through connections formed between their roots and the roots of the pine trees and The Leucochloridium worm infects snails and is able to control the snail's behavior, creating a zombie-like snail. The worm forces the snail to attract predators to itself so that the worm is eaten and passed to its next host are parasitism relationship because parasitism is a relationship that exists between two organisms in which the other called the predator infect , harm or cause damage to the host organism. The above are parasitism relationship because they cause damage to their host.
Mutualism
The bullhorn acacia grows special tissues in which ants live. The ants find a safe place to live and attack any animals that attempt to graze on the acacia and On the Galapagos Islands, there are finches that remove parasitic insects from tortoises. The finches gain a meal and the tortoises are ridded of parasites exhibit mutualism relationship because mutualism is a symbiotic relationship that exists between two organisms in which both benefits from the relationship. The Acasia and the ants receive protection from the relationship. The finches and tortoise benefited from their relationship.

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.
