electrons
B.
neutrons
Oc.
nucleus
OD.
protons
Reset
Answer:
C NUCLEUS
Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons.
Why is it difficult to bond three phosphate groups to Adenosine?
They have the same charge and repel each other.
They form a strong attraction to each other.
They are like opposite poles of a magnet.
The energy is evenly dispersed across all three bonds.

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.

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.
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

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.

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

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.
