Explanation:

The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.

This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.  

Answer:

A. RNA

Explanation:

DNA has the chemical base of thymine, while RNA does not.

Instead, RNA has the base of uracil, to replace thymine.

Since the analogy relates thymine to DNA, uracil must be related to RNA.

So, A is the correct answer.

Thymine is to DNA as Uracil is to RNA.

Among the given options, immigration is considered as the limiting factor to a population. Thus, the correct option is D.

A Population may be defined as the number of individuals of the same species living in a particular area at a definite time. It also represents the number of males and females in any population with respect to their characteristics.

Competition, predation, and human disturbances are responsible for the reduction of any population. This is because these factors generally involve the ultimate death of individual and health damage.

While immigration is typically a process through which an individual has come in order to live in that place. This place is not native to the individual. This increases the population of any specific region.

Therefore, among the given options, immigration is considered as the limiting factor to a population. Thus, the correct option is D.

Answer: Andrew Jackson was a strong president. He used the office to forcefully pursue his agenda. This cartoon is quite famous, coming out around 1833, because of the 1833 removal order. In the cartoon, the president can be seen holding a veto in his hand, and standing on top of the Constitution. He is dressed up as a king, holding - perhaps - too much power. I believe that the intended audience was the people. The people saw him as a king, abusing his powers as a president. The author’s purpose was to show how people truly viewed him. The president’s order to remove federal deposits from the Bank of the United States led to an increase in state debt. The President was strongly criticized because he acted without congressional approval, as a king would.

President Andrew Jackson was an enigmatic and strong personality during his tenure as President of the United States of America.

As a result of this, there was a cartoon which was created to help further his agenda. In it, he is depicted holding a veto power on top of the Constitution, while dressed in royal attire.

He wanted to show that he was a man of the people but it was viewed as a person who was wielding too much power than was suitable for a president as he occasionally acted without congressional approval.

Answer:

When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.

The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.

There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.

Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water

Answer:

DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.

DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.

DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

Explanation:

DNA ligase seals the fragment, DNA polymerase adds a new nucleotide, DNA gyrase unwinds the DNA, and helicase makes a dent in double helix.

DNA replication is the physiological method that generates two identical replicas of DNA from a single original DNA molecule in molecular biology.

DNA replication takes place in all living organisms and is the most important component of biological inheritance.

Helicase, primase, DNA polymerase, and ligase are the four main enzymes that aid in DNA replication.

Many proteins and enzymes play a role in DNA replication, including: Topoisomerase: This enzyme relaxes the super-coiled nature of DNA. Helicase: Helicase is a protein that separates the two strands of DNA at the replication fork.

The fragment is sealed by DNA ligase, a new nucleotide is added by DNA polymerase, the DNA is unwound by DNA gyrase, and a dent in the double helix is made by helicase.

Thus, this can be the match for the given scenario.

Answer:

La estructura formada por adición de vesículas procedentes del aparato de golgi que permiten la aceptación durante la citocinesis en las células vegetales se denomina Fragmoplasto o Tabique.

Explanation:

El fragmoplasto o tabique es una estructura que no se encontrará en las células animales, sino vegetales. Viene a ser una especie de "puente" entre la pared celular que luego se dividirá, dando lugar a dos células.

Durante la anafase y telofase los distintos filamentos y microfilamentos del fragmoplasto se acumulan de manera opuesta para dar paso a la nueva pared celular.

A diferencia de la citocinesis en las células animales que se da por un mecanismo de estrangulación, en las células vegetales se logra por tabicación.

What is a lipid that makes up cell membranes and is used to create hormones?

cholesterol**

Cholesterol makes up cell membranes and is used to create hormones.

Cholesterol is a necessary lipid for the body as it contributes to the formation of cell membranes and hormones. However, high amounts of cholesterol in the blood have harmful consequences for health.

Cholesterol has different functions in the body such as:

- Formation of structures: It is one of the main components of the plasma membranes of animal cells.

- Contributes to the formation of hormones: sex hormones (progesterone, estrogens, and testosterone), corticosteroid hormones (cortisol and aldosterone).

- Contributes to the metabolization of calcium to obtain vitamin D.

Additionally, the options hydrocarbon (natural chemical compound obtained from the earth to be used as fuel), starch (natural macromolecule that contributes to the human digestion process) and glucose (the most abundant chemical compound in nature that serves as a source of energy for organisms) are not correct options, because these substances do not have the function of forming cell membranes and creating hormones.

The concentration difference and surface area lead to decrease but the diffusion distance increases due to application of chlorine.

The difference in the concentration of a substance between two regions is known as the concentration gradient.

Surface area is the total area that the surface of the object occupies.

Diffusion rate is defined as the change in the quantity of diffusing molecules inside the cell in a specific period of time.

The chlorine gas greatly affected the concentration difference because it lowers the value. The gas increases the diffusion distance but decreases the surface area of the patient's lungs. The decrease in the concentration difference leads to slower the diffusion rate.

It is because there is less difference in the concentration of both regions i.e. lungs and the surrounding atmosphere and when there is equal amount on both sides the diffusion of gas molecules stopped so we can say that decrease occur in the concentration difference and surface area but increase occur in the diffusion distance

There is an important relationship among  homeostasis, defective mitochondria, and the  symptoms caused by LHON.

Explanation:

There is a great relationship among  homeostasis, defective mitochondria and the  symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.

The relationship among homeostasis, defective mitochondria and the symptoms caused by LHON is the following:

The power center of the cell, the mitochondria are also involved in homeostasis, the maintenance of a stable internal environment even in the face of variations in the external environment.

Mitochondrial diseases can be caused by inherited mutations in mitochondrial DNA or defects in the proteins responsible for regulating mitochondrial division, affecting the body's homeostasis.

Therefore, we can conclude that LHON is a disease associated with a mutation in the mitochondrial genome affecting the body's homeostasis.

Answer:

The chemical compound that breaks down the insects is most likely enzymes.

Explanation:

Venus flytraps and sundews are carnivorous- they consume insects to absorb nutrients via digestion. During absorption,  their cells take up molecules synthesized via the breakdown of macromolecules like carbohydrates and proteins. When regions of the plant come into contact with insects, these plants recognize specific macromolecules like chitin, they increase the production of digestive enzymes.

Forming digestive liquid enzymes are specialized proteins that function as biological catalysts to speed up reactions. They act on substrates, which can bind to specific regions of the enzyme, called the active site. Once bound in the presence of highly specific temperature and pH, enzymes increase the rate of a reaction over time.

Common enzymes found in their digestive secretions include chitinases, phosphatases, amylases, and proteinases.

Answer:

decrease the base of support and centralize her line of gravity

Explanation:

A wider base of support leads to an unsteady gait. The base of support is the contact between the feet of the soccer player and the surface (the field) supporting him. The root cause of the player's inability to react quickly to the movements of the opposing player is a lack of balance.

Balance is the ability of an individual to sustain the line of gravity which runs the center of gravity. For the player to regain his balance, she needs to decrease the base of support and centralize her line of gravity, so as to maintain balance.
