Explanation:
Logistic regression is also vulnerable to overfitting. It cannot be applied to a non-linear problem. It will perform poorly with independent variables which are not correlated to the target and are correlated to each other.

Which of the following describes the most likely location of cholesterol in
an animal cell?
*
Embedded in the plasma membrane
Dissolved in the cytosol
Suspended in the stroma of the chloroplast
Bound to free ribosomes
Based on the diagram, what is the site of modification and packaging of
proteins and lipids prior to export from the cell?
Answer:
1. Embedded in the plasma membrane
2. There is no diagram attached but the question can be answered based on general knowledge. The answer is Golgi apparatus/body.
Explanation:
1. Cholesterol is fat molecule produced in the Smooth Endoplasmic reticulum of animal cells. It is then transported to the plasma membrane, where it plays a vital role in the functionality of the plasma membrane. Hence, embedded in the plasma membrane of an animal cell is CHOLESTEROL, in addition to phospholipids.
2. The Golgi apparatus is an organelle in eukaryotic cells that functions in the modification and packaging of protein and lipid molecules produced by the RER and SER respectively.
The most likely location of cholesterol in an animal cell is A. Embedded in the plasma membrane.
Based on the diagram, the site of modification and packaging of proteins and lipids prior to export from the cell is the Golgi apparatus.
Cholesterol simply means a fat molecule that is formed in the smooth endoplasmic reticulum of animal cells.
It should be noted that the cholesterol is then sent It is then to the plasma membrane,
The Golgi apparatus is an organelle that can be found in eukaryotic cells. The function of the Golgi apparatus is the modification and the packaging of the lipid molecules and the protein molecules that are produced.

Students constructed a diagram to represent two related cellular processes.
F. Photosynthesis
G. Cellular respiration
H. DNA replication
J. Protein synthesis
Answer:
F. Photosynthesis
Explanation:
The organelle pictured (a chloroplast) seems to be absorbing energy from the sunlight and that is included in the process of photosynthesis.
The carbohydrates (glucose) are formed by the process of photosynthesis in the chloroplast of the cell which then sent to the mitochondria for the production of ATP through glycolysis. Thus, the correct option is F.
What is Photosynthesis?
Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (glucose). This process takes place in the chloroplast of plant cell where chlorophyll is present, this pigment (chlorophyll) is responsible for trapping the sunlight which is responsible for conduction of photosynthesis.
The products of photosynthesis (glucose) is sent to the mitochondria of cell for the production of ATP by the process of glycolysis. This ATP is then utilized by the cell in other cellular mechanisms.
Therefore, the correct option is F.

Another students says that the earth’s magnetic poles have flipped many times in the past. How would you evaluate their statement?
Question 18 options:
This is a true statement.
This false because the magnetic field is fixed and cannot change.
This is false because a compass always points at the true North Pole.
This is false because the magnetic field has only flipped once.
Answer:
True
Explanation:
As a matter of geological record, the Earth's magnetic field has undergone numerous reversals of polarity. We can see this in the magnetic patterns found in volcanic rocks, especially those recovered from the ocean floors. In the last 10 million years, there have been, on average, 4 or 5 reversals per million years.

Explanation:
A species is a group of organisms capable of mating and producing offspring, and speciation is the process of forming a new species.
One way a new species may form is by geographic isolation. This occurs when members of a population are physically separated, for example, by a river, or a desert.
After the separation the two populations, responding to different conditions, will adapt differently, and so their evolutionary paths will...

During cell respiration, the reactants of glucose and oxygen are transformed into the products of carbon dioxide, water, and ATP. Which of the following cell transport processes would be relatively unaffected if a cell no longer had access to glucose? Choose 1 answer: Choose 1 answer: (Choice A) A The transport of calcium into a muscle cell via facilitated diffusion. (Choice B) B The transport of an amino acid into an intestinal cell from an area of low concentration to an area of high concentration gradient. (Choice C) C The transport of sodium against its concentration gradient in a brain cell. (Choice D) D The passive transport of a charged potassium ion (K^+ + start superscript, plus, end superscript) through a cell membrane.
The process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.
What is Cellular respiration?Cellular respiration may be defined as the chemical process through which the breaking down of food occurs with the liberation of energy. This process takes place in the excess of oxygen and constructs energy from carbohydrates (sugars).
The excess glucose delivers the required energy for the cell to perform its metabolic activities. But when the amount of glucose is not significantly present in the cell, the process of transport of calcium into a muscle cell via facilitated diffusion remains unaffected.
This is because the transport of calcium occurs due to paracellular passive transport without the utilization of energy. While the rest of the process requires energy for the transport.
And due to a lack of glucose, cells do not have the ability to derive energy in form of ATP.
Therefore, the process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

Which element is more difficult to take electrons away from tin or Gallium and why ?
Cesium (Cs) in particular can surrender its valence electron quite conveniently than lithium (Li). In fact, the ease with which the alkali metals give up an electron varies as follows: > Cs > Rb > K > Na Li is the most likely to lose an electron, followed by Cs and Li.
What is reactivity?In chemistry, reactivity is the impulse that causes a chemical substance to undergo a chemical reaction, either on its own or in conjunction with other materials, resulting in the release of energy.
The reactivity of an element is a measure of how easily it will combine with other elements to form substances.
The number of electrons in an atom's outermost shell determines its reactivity. Noble gases have low reactivity so even though their electron shells are complete.
Cesium (Cs) in particular can more easily surrender its valence electron than lithium (Li).
In fact, the alkali metals' ability to give up an electron varies as follows: > Cs > Rb > K > Na Li has the highest probability of losing an electron, followed by Cs and Li.
Thus, these are some elements that is more difficult to take electrons away from tin or Gallium.

Why would a plant cell not burst while an animal cell would undergo cytolysis in a hypotonic solution?
The plant cell has a large central vacuole and creates a stronger exterior.
The plant cell has a rigid cell wall and the pressure from the central vacuoles causes the stiffness of the plant and animal cells do not have a cell wall therefore the boundary of the cell is weaker.
The plant cell is stronger because it has the chloroplast and causes a strong boundary that support the cell due to the glucose that is made from the process of photosynthesis.
