Timothy does not get a promotion at work because he has cancer is an example of genetic discrimination.
Explanation:
Genetic discrimination is termed so when an employer or an insurance company treats indifferently an individual with gene mutation or heritable diseases.
The act of not giving promotion and using the genetic information for the reason by the employer is indifferent and termed genetic discrimination as in case of cancer where life expectancy and large insurance claim is the reason.
Insurance companies do not give benefits or insurance to potential people having or prone for having the mutation and heredity disease.
To help overcome this discrimination federal level laws have been implemented as Genetic information non discrimination act. It strictly prohibits the indifferent behaviour of the employers and insurance companies.

the galapagos tortoise are biodiverse. tortoises in a more barren area have a flat shell and long neck to help grasp the sparse vegetation. tortoises that live in a more vegetated island, have more round shell and shorter necks. this is an example of
Final answer:
The diverse shell shapes and neck lengths of Galápagos tortoises represent examples of adaptive evolution and natural selection, with differences suited to their specific island environments.
Explanation:
The differences in shell shape and neck length of the Galápagos tortoises are excellent examples of adaptive evolution. Tortoises with saddle-shaped shells and longer necks are adapted to islands with sparse vegetation, where they need to reach higher to grasp food. Conversely, tortoises with dome-shaped shells and shorter necks are adapted to islands with more abundant ground vegetation, where there's less need to reach high. These variations in physical traits are consistent with Charles Darwin's observations and underscore the concept of natural selection, where environmental pressures influence which traits become more common in a population over time.

What is the purpose of meiosis? How does the cell do the following: reduce the chromosome number in half and create genetically different cells?
Answer:
2 cells meet and the number of chromosomes becomes equivalent to the somatic cell.
Explanation:
In meiosis crossing over occurs and the number of chromosomes divided or remain half as compared to a somatic cell which is called Haploid (n). When two haploid cell meets than diploid (2n) cell formed which further transforms into a zygote. So, the purpose of meiosis is the cross over which creates genetic variation among individuals and reduced the number of chromosomes into the half. Because if the number of chromosomes remains the same as (2n) and (2n) meets and becomes 4n. Which is the wrong pattern so nature keeps this balance in a unique manner that (n) and (n) meets and form (2n).

Explanation:
Answer:
When muscles contract and relax, the muscles move the attached to them. This results in the movement of bones.
Explanation:
Skeletal muscles are the part of the muscular system, which are attached to the bones via tendons. The contractions or relaxation of muscles is primarily caused due to skeletal muscles. These muscles cause the mechanical movement of the body parts. These tendons are present at many joints of the body allowing muscle movement, which eventually causes bone movement.
Thus, all the vertebrates move by the action of bones. Tendons play a crucial role in the attachment of bone to the muscles. These muscles when contract or relax, cause the movement of the bones. These muscles work in antagonism, such that when one muscle flexes, the other one relaxes.

What are the two factors that
affect an object's kinetic energy?
An object's kinetic energy is influenced by its mass and velocity. The kinetic energy of an object is determined by the equation KE = 1/2 mv^2, implying that larger objects moving at faster speeds have more kinetic energy.
Explanation:The two factors that affect an object's kinetic energy are its mass and its velocity. Kinetic energy is defined as the energy of an object in motion. The equation to calculate kinetic energy is KE = 1/2 mv^2 where m is the mass of the object and v is its velocity. Based on this equation, it's clear that an object with a larger mass or a higher velocity will have more kinetic energy. For instance, a heavy truck moving at a high speed has more kinetic energy than a small car moving at a slow speed.

How is it possible that over 20 million living organisms on the planet are made up of only 5 types of nucleotide based arranged in long chains?
Answer/Explanation:
The DNA in all living organisms is made up of 4 bases, adenine, thymine, guanine, cytosine. The RNA replaces thymine with uracil, making 5 types of nucleotide. The number of nucleotide pairs in a genome can range from half a million up to 100,000 million - meaning there are an exponential number of combinations of these 4 bases.
Imagine an organism exists that has only 2 nucleotides (this is over 200,000x smaller than even the smallest bacterial genome). If we allow any nucleotide at each of the 2 positions, then we have 4x4 (4²) or 16 possible combinations of sequences. For a nucleotide length of 4, the total number of possible combinations are 4⁴ or 256.
Since we are dealing with many millions of nucleotides, there are essentially infinite combinations of nucleotides, giving rise to the variation that produces over 20 million organisms on the planet.
Which of the following is an example of water transferring from the atmosphere to the cryosphere?
A.
Rain falls on the Earth's surface and seeps into the ground, forming a groundwater reservoir.
B.
An iceberg floats into warm waters and melts.
C.
A riverbed dries up during a severe heat wave and drought.
D.
Snow falls on a glacier and is gradually compacted into ice over many years.
Just did it its D
Answer:
Snow falls on a glacier and is gradually compacted into ice over many years.
Explanation:
Option D is correct because it directly related to the phenomenon of transferring water from the atmosphere to the cryosphere. The cryosphere is the frozen part of Earth that mainly represent Antarctica and the Arctic. Therefore, snow falling on the glacier and continuous compacting over the years represent the transferring of water from the atmosphere to the cryosphere.
One the other hand, A, B, and C are incorrect options. A describes a phenomenon in which atmospheric water restore groundwater storage via seepage. B represents a situation where frozen water (cryosphere) melts and form surface water (oceanic water.) C is a condition where evaporation causes drying of a river resulting in drought.
Answer:
Snow falls on a glacier and is gradually compacted into ice over many years.
Explanation:
The cryosphere describes all of the solid water on Earth's surface, including glaciers, icebergs, snowpack, and ice. The atmosphere is the layer of gases that surrounds the Earth. Water very often transfers between the atmosphere and cryosphere. When snow falls on a glacier and is gradually compacted into ice over many years water from the atmosphere is becoming a part of the cryosphere.
If 48 g of magnesium reacts with oxygen gas, how many grams of magnesium oxide will be
formed according to the following equation?
2 Mg + O2 → 2 Mgo
79.391 grams of MgO is formed when 48 gms of magnesium reacts with oxygen gas.
Explanation:
Balanced equation to show the production of MgO from Mg and oxygen.
2 Mg + O2 → 2 Mgo
From the equation it can be concluded that 2 moles of Mg is required for the formation of 2 moles of MgO.
now, the given weight of Mg is 48 grams
atomic weight of Mg= 24.3 gram/mole
We can calculate the number of moles in 48 grams of Mg by applying the following formula:
number of moles= mass of the substance or element given÷ mass of the one mole of the element.
Putting the values in the above equation
n= 48÷24.3
= 1.97 moles of Mg
Applying the stoichiometry it can be found that
2 moles of Mg gave 2 moles of MgO
1.97 moles of Mg gave x moles of MgO.
Solving for x
2÷2=1.97÷x
x= 1.97
Thus 1.97 moles of MgO is formed, to know the weight in grams we can use the formula used above as
mass = n × atomic mass
= 1.97 × 40.30 grams/mole
= 79.391 grams of MgO is formed.
Using stoichiometry, 48 grams of magnesium will react with oxygen to form 79.602 grams of magnesium oxide.
Explanation:To determine how many grams of magnesium oxide (MgO) will be formed when 48 grams of magnesium (Mg) reacts with oxygen (O2), we will use the stoichiometry of the balanced chemical equation:
2 Mg + O2 → 2 MgO
First, we need to calculate the molar mass of magnesium and magnesium oxide:
Molar mass of Mg = 24.305 g/molMolar mass of MgO = 24.305 (Mg) + 16.00 (O) = 40.305 g/molNow, using the stoichiometry of the reaction:
Determine how many moles of Mg are in 48 grams: moles of Mg = 48 g / 24.305 g/mol = 1.975 mol.According to the balanced equation, 2 moles of Mg produce 2 moles of MgO, so 1.975 mol of Mg will produce 1.975 mol of MgO.Finally, convert moles of MgO to grams: mass of MgO = 1.975 mol * 40.305 g/mol = 79.602 g of MgO.Therefore, 48 grams of magnesium will produce 79.602 grams of magnesium oxide.

Which phrase describes the relative age of a rock?
1.uses the law of superposition to determine which rock is older or younger
2.can determine the age based on location of a rock within the same layer
3.requires only one rock to determine the age
4.can provide the exact age of a rock
Answer:
1, if you know that a rock was deposited after the one you are attempting age then you know that the "deeper" one is older.
Explanation:
The relative age of a rock is described by using the law of superposition, which helps determine the older or younger status of rock layers without providing an exact age.
Explanation:The phrase that describes the relative age of a rock is: uses the law of superposition to determine which rock is older or younger. This method of relative dating is essential in determining the chronological sequence of rock layers. By observing rock strata, geologists apply the law of superposition which stipulates that in undisturbed layers of sedimentary rocks, the oldest layer is at the bottom, with successively younger layers stacked above it. Thus, the relative ages of rocks and fossils can be discerned based on their positions within these layers.

They have cooler temperatures than places at lower altitudes.
They have warmer temperatures than places at lower altitudes.
They have the same temperatures as places at lower altitudes.
They have less predictable temperatures than places at lower altitudes.
Answer:
A
Explanation:
In general, places at higher altitudes are cooler than those at lower altitudes due to the thinner atmosphere and less heat absorption from the sun.
Explanation:In general, places at higher altitudes have cooler temperatures than places at lower altitudes. This is because the atmosphere becomes thinner with increasing altitude, causing less heat to be absorbed from the sun. Thus, high-altitude locations like mountain tops are colder compared to low-lying areas such as sea level regions. One familiar example is Mount Everest, the highest peak in the world, which is perpetually covered in snow due to the extremely cold temperatures at its high altitude.
