Answer:
the forces between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them
Answer:
The force becomes 4 times as much when the distance is halved.
Explanation:
F1 = k*q1 * q2/r^2 = kq^2/r^2
F2 = kq^2/1 / (r/2)^2
Set up a proportion using F1/F2 as you reference.
Notice that you don't know any number that can be used in this equation. However k q^2 does not change as you move the two charges closer together. That being so, you can still show what happens to F1 and F2.
F1/F2 = 1/r^2 // 1/(r^2/4)
Take the denominator, invert the fraction and multiply. That creates another cancellation.
F1/F2 = 1/r^2 * r^2 /4 1
F1/F2 = r^2 // r^2/4 which allows you to cancel r^2
F1/F2 = 1/4 Now you need to interpret F1 and F2. Cross Multiply
4F1 = F2
How are protons and neutrons conserved as a star ages?
Answer:
Students identify that atoms are not conserved in nuclear fusion, but the total number of protons plus neutrons is conserved. ... Helium and a small amount of other light nuclei (i.e., up to lithium) were formed from high-energy collisions starting from protons and neutrons in the early universe before any stars existed.

If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, what mutation must have occurred?
A. A nondisjunction mutation in the gamete of one of the parents
B. A nondisjunction in both gametes of the parents
C. A nondisjunction in one of the first gamete cells of the individual
D. A nondisjunction mutation in body cells of both parents
Answer:
if An individual has an extra chromosome in every one of its cells, the mutation that must have occurred is A non-disjunction mutation in the gamete of one of the parents
If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, the mutation that must have occurred is A. A nondisjunction mutation in the gamete of one of the parents.
Down syndrome simply means a genetic disorder that is caused when there's an abnormal cell division that then leads to extra genetic material.
The effect of Down syndrome is the fact that it leads to an intellectual disability, developmental delays, and a distinct facial appearance.
The mutation that has occurred with someone that has a Down syndrome is the nondisjunction mutation in the gamete of one of the parents.

Answer:
Connective tissue is a group of tissues in the body that keep the body and its organs in shape while also providing cohesion and internal support.
All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.
What is connective tissue?
Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.
Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.
Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.

Climate change is expected to alter the ocean’s temperature, salinity, acidity, and currents. What would you want to investigate to find out how these changes would affect the way oceanic bacteria will process dissolved organic carbon in the future?
Answer:
Even though an individual phytoplankton is tiny, there are many of them in the ocean. Their combined effect on atmospheric CO2 is comparable to that of every plant on land. ... Then they exude altered dissolved organic carbon into the water (the bacterial equivalent of pee and poop) and respire carbon dioxide into the air.
Explanation:
Annette has her thyroid gland removed because of a malignant tumor. She takes synthetic thyroid hormone to replace the thyroxine that her thyroid gland would have produced, but she is worried about her blood calcium level since she has lost her source of calcitonin. Does she need to worry about this problem
Answer:
She doesn't need to worry if her parathyroid glands are working.
Explanation:
Although Annette has to worry about the impacts of thyroid gland removal and synthetic thyroid hormone intake, the calcium levels in her body need not be a concern as long as her parathyroid glands are functioning normally.
This is because the parathyroid glands are responsible for regulating calcium levels in the blood, through the production of parathyroid hormones or parathormone.

Using a simple aproxamation above,calculate the volume of the right circular cylinder with a radius of 2 meters and a height of 9 m
Answer:
Volume = 113.112 m³
Explanation:
Given the following data;
Radius = 2 meters
Height = 9 meters
To find the volume of a right circular cylinder;
The volume of a right circular cylinder is calculated by multiplying the area of its circular base with the height of the cylinder.
Mathematically, the volume of a right circular cylinder is given by the formula;
Volume= πr²h
Where;
r is the radius of the circular base.
h is the height of the cylinder.
Substituting the values into the formula, we have;
Volume = 3.142 * (2)² * 9
Volume = 3.142 * 4 * 9
Volume = 113.112 m³

Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

¿Cuál se considera la “barrera simbólica” del nivel de CO2 en la atmosfera? ¿Cuál es el nivel de CO2 en la actualidad? ¿Qué significa esto? Menciona tres consecuencias de esta situación.
Answer:
413,55 ppm
Explicación:
413,55 ppm es el nivel de dióxido de carbono actual en comparación con el nivel de dióxido de carbono que es de aproximadamente 280 ppm antes de la revolución industrial. Esto significa que la revolución industrial aumenta la concentración de gas dióxido de carbono en la atmósfera, que es la principal causa del derretimiento de los glaciares, el cambio climático y el calentamiento global. Hay una gran cantidad de dióxido de carbono que se libera de las industrias, lo que es responsable del aumento de la concentración de dióxido de carbono en la atmósfera.

In an experiment, researchers find that certain neurons in the visual cortex preferentially fire in response to a bar of light that is oriented at a specific angle, and that different neurons similarly respond to bars of light oriented at different angles. This finding provides the strongest evidence for:
Answer:
Feature detection
Explanation:
Feature detection involves different neurons that are activated in response to specific stimuli. For example, feature detectors are activated in the cerebral cortex through visual stimuli of specific shapes or patterns. These neurons become more and more complex as the stimuli also become progressively more complex and specific. Featured detector neurons have been identified in the toad vision, where they have been involved in the toad's behavior in response to worm-like moving stimuli (e.g., orienting), and the bat auditory cortex, where they have been involved in the measurement of the distance between the bat and its prey.
