What causes a tornado to form? Water vapor condenses, giving off energy. Wind over ocean water forces water vapor upward. A warm, moist air mass collides with a cold, dry air mass. Air pressure changes suddenly, causing rapid air movement.
Answer:
A change in wind direction cause the air to spiral. Then, warm humid air rises up in the inside of the tornado while cold dry air goes down. These things cause the spinning air currents inside the tornado.
hope this helps!
Suddenly, air pressure changes that significantly cause rapid air movement which ultimately leads a tornado to form. Thus, the correct option is D.
What is meant by a tornado?A Tornado may be characterized as a type of natural phenomenon that significantly involves vehemently rotating columns of air touching the ground, usually attached to the base of a thunderstorm.
Tornadoes are generally considered nature's most violent storms. They are generated by powerful thunderstorms and have the ability to cause fatalities and devastate a neighborhood in seconds.
Winds of a tornado may reach 300 miles per hour. Apart from this, a tornado may evolve within a cyclone and form due to the influence of low pressure in the eye of a cyclone.
Therefore, suddenly, air pressure changes that significantly cause rapid air movement which ultimately leads a tornado to form. Thus, the correct option is D.

What response would likely occur in an animal if the environmental temperature increased?
O blinking
O grouping
o shedding
CAN
shivering
Answer:
shedding
Explanation:
they would lose hair/fur allowing more waste heat to be lost into the environment so that the body could be cooler.
If the environmental temperature increases, the animal is most likely to shed, which is present in the third option because shedding the fur that is present on the skin is helpful for the relief of the heat.
What is the significance of the heat in the animal body?Heat regulates the internal temperature, organ activity, blood pH, and a variety of other functions in the animal body. Animals living in colder climates have more hair and fat than those living in warmer climates, which is due to their need to protect their internal body temperatures. In the case of colder weather, the skin or the fur acts as an insulator and protects the animal by conserving the heat, while in a hot climate, the animals shed these in order to release the heat.
Hence, as the environmental temperature increases, the animal is most likely to shed, which is present in the third option.

Enzymes that catalyze consecutive steps in a metabolic pathway often cluster together in a cell.
Which of the following statements describes a likely result of this clustering?
Choose 1 answer:
А
Pathway intermediates are prevented from entering alternative metabolic pathways.
В
Enzyme crowding decreases the efficiency of each enzyme in the pathway
The cell can be affected by toxic intermediates.
D
The enzymes in a pathway do not have enough reaction substrate to function efficiently
Answer: pathway intermediates are prevented from entering alternative metabolic pathways
Explanation: the clustering of enzymes in a metabolic pathway ensures that the product of one enzyme is efficiently transferred to the next enzyme in the pathway. So, the clustering prevents pathway intermediates from being diverted into alternative metabolic pathways.
The statement that best describes the most likely result of this clustering of enzymes is as follows:
Pathway intermediates are prevented from entering alternative metabolic pathways.Thus, the correct option for this question is A.
What are Enzymes?Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being altered in the complete process. It is thought that all cellular reactions or processes are mediated by enzymes.
According to the context of this question, the process of assembling or clustering enzymes in any metabolic pathway makes sure that the outcome of one enzyme is operating as the reactant of the next enzyme in the same metabolic pathway.
So, the process of clustering effectively restricts the formation of intermediates and the regulation of alternative metabolic pathways.
Therefore, the correct option for this question is A.

In dragons, green scales are dominant to brown scales. A mating between a dragon with green scales and a dragon with brown scales produces offspring with a speckled pattern of green and brown scales. What are the genotypes of the two parents and the offspring?
Answer:
The correct answer would be -
parent 1: GG
parent 2: gg
offspring: Gg
Explanation:
Let assume the dominant allele of the dragon scale is represent by G and the recessive allele that expressed in brown is represented by g. As it is given that offspring by mating is expressing this trait as a speckled pattern of both alleles brown and green which means it shows codominance where both alleles expressed together in offspring if present in heterozygous condition.
So, the cross between GG and gg will result in a heterozygous combination to produce offspring with a speckled pattern of brown and green scales.
The correct answer would be -
parent 1: GG
parent 2: gg
offspring: Gg

Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon
between two Earth systems.
Answer:
Photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere by using carbon dioxide present in the atmosphere to produce sugars found in plants.
Note: The model is found in the attachment below
Explanation:
The atmosphere is the layer of gases forming an envelop around the earth. The earth's atmosphere is composed of mainly nitrogen and oxygen as well as other gases such as carbon dioxide and water vapor.
The biosphere refers to the regions of the earth's surface on which living organisms can be found. It includes the land, air and water.
Carbon dioxide is cycled between the atmosphere and the biosphere by the process of photosynthesis which is the process by which green plants manufacture their food with the aid of energy from sunlight.
From the model, in the first stage, energy of sunlight is trapped by light-dependent reactions and is used it to make ATP and NADPH. During the second stage, the light-independent reactions use ATP and NADPH reduce carbon dioxide from the atmosphere to sugars and ADP and NADP⁺.
Thus, photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere.

Explanation:
Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier.
Answer:
Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier.
Explanation:
"Acceleration due to gravity" typically refers to the increase in speed of a falling object due to the gravitational pull of the Earth. If jump out of a plane, your speed increases towards the Earth (or the center of the Earth really) due to the acceleration of gravity. If you throw a ball up in the air, it slows down and falls due to the acceleration of gravity. I guess it's specified because the force of gravity is causing the acceleration in these instances; as opposed to some other outside force.

Which of the following is an example of homeostasis?
Humans shiver when it is very cold.
We cover ourselves with a blanket when it is cold.
We take a shower to keep the body temperature low.
An air conditioner keeps the body at a normal temperature.
i think its A, B, or C
Answer:
Humans shiver when it is very cold.
Explanation:
"Homeostasis" is the ability of the body to regulate itself in order to maintain a steady state. This includes mechanisms that allow automatic adjustment when the need for it arises. Covering ourselves with a blanket, taking a shower and turning on the air-conditioner are "not self-regulated" activities because they are done "intentionally" by the person. It is only "shivering" that shows the body's regulation of heat.
When the environment is cold, the skeletal muscles of the body respond by rapidly contracting and relaxing. This is what you call as "shivering." It produces heat through "respiration." Thus, it helps increase the body temperature.

Susan and Michael travel on separate trains. Susan's train moves westward at a constant speed of 5 meters per second. Michael's train
moves eastward at a constant speed of 7 meters per second. How fast is Susan's train moving relative to Michael's train?
Answer:
[tex]V =2m/s[/tex]
Explanation:
Given:
Represent
- Susan's velocity with [tex]V_s[/tex]
- Michael's velocity with [tex]V_m[/tex]
[tex]V_m = 7m/s[/tex] eastwards
[tex]V_s = 5m/s[/tex] westwards
Required
Determine how fast is [tex]V_s[/tex] relative to [tex]V_m[/tex]
From the question, one train moves eastwards while the other moves westwards.
This means that travel in opposite travel and the relative speed (V) is calculated as:
[tex]V = V_m - V_s[/tex]
Substitute values for [tex]V_s[/tex] and [tex]V_m[/tex]
[tex]V =7m/s - 5m/s[/tex]
[tex]V =2m/s[/tex]
Hence, the Susan's train is moving 2m/s in relative to Michael's train

What does the Teacher's Pet Video: Mitosis and Meiosis give as the main reason for the production of haploid cells during meiosis?
O because the two haploid cells will fuse together to make a new genetically different diploid cell that will form the offspring
O because the sperm brings all of the father's genes to the egg allowing for the baby to have a different number of chromosomes
c. because the egg and the sperm will then be able to each form a new diploid offspring through the process of mciosis
d. because both the parents' and offspring's diploid cells will then be genetically identical to one
Answer:
The main reason for the production of haploid cells during meiosis is because the two haploid cells will fuse together to make a new genetically different diploid cell that will form the offspring.
Explanation:
In the context of sexual reproduction, meiosis is the process of cell division by which gametogenesis occurs. In this process, diploid cells are used to obtain haploid cells, called gametes.
The reduction of the chromosomal charge that occurs in meiosis is aimed at producing haploid cells —with half of the crosmosomes of a species— so that when the parents' gametes join, they form a diploide cell called zygote.
Zygote is the starting point for the development of a new individual, part of the offspring.
