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.

What factors will effect how much gravity
accelerates a falling object?
Answer:
Mass and distance
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.

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.

c) Carrier females have the genotype XFXf.
d) There are four possible genotypes, XFXf, XfXf, XFY, XfY
Explanation:
The mutation for hemophilia is on the X chromosome. Females have two X chromosomes and males have one.
Let's say that the mutated allele is f and the normal allele is F.
A carrier female has the genotype XFXf. A hemophilic man has one X chromosome. and since he is affected, must have the mutated allele. He must have the genotype XfY.
The punnett square below shows the cross
XF Xf
Xf XFXf XfXf
Y XFY XfY
a) As we saw, carrier females have the genotype XFXf. In the cross, there 1:4 chance that phenotype will occur.
b) A normal male has the genotype XFY. In the cross, there 1:4 chance that phenotype will occur.
c) Carrier females have the genotype XFXf.
d) There are four possible genotypes, XFXf, XfXf, XFY, XfY
A solution that has 0% salt is____to a cell with 40% salt concentration
Answer:
The solution is hypotonic
Explanation:
Molecules in a solution move from highly concentrated regions to regions of low concentration in an effort to reach a state of equilibrium- where the molecules are equally distributed. This always occurs with the molecules moving down the concentration gradient.
Solutions can be:
hypertonic, or more concentrated; hypotonic- less concentratedisotonic- same concentrationAt 40% salt concentration, solution A is hypertonic while the less concentrated solution at 0% salt concentration is hypotonic.

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.

Answer: Oxygen, Lactic acid, liver, mitochondria
Explanation: Lactic acid fermentation occurs in muscle cells when OXYGEN levels are low. When LACTIC ACID builds up in muscles it causes pain and muscle fatigue. Usually, the lactic acid diffuses into the bloodstream over time and is filtered out by the LIVER and converted into glycogen and then to glucose. However, with proper training, lactic acid can transfer to the MITOCHONDRIA of muscle cells, where it is broken apart for its energy.
Lactic acid is produced as the byproduct of the anaerobic respiration. The correct answers are oxygen, lactic acid, liver, and mitochondria.
Lactic Acid Fermentation:
During the intense exercise, body become unable to fulfill the need of oxygen. Hence, body start producing energy anaerobic respiration and produce a by-product, lactic acid. This results in build up of the lactic acid in muscle which cause muscle fatigue.
Lactic acid fermentation occurs in muscle cells when Oxygen levels are low.When lactic acid builds up in muscles it causes pain and muscle fatigue. The lactic acid diffuses into the bloodstream over time and is filtered out by the Liver and converted into glycogen and then to glucose.
