what needs to occur for a fluorescent mineral to give off light?

Answers

Answer 1

Fluorescent minerals contain particles in their structure known as activators, which respond to ultraviolet light by giving off a visible glow. Ultraviolet light is a form of electromagnetic radiation invisible to the human eye. There are two classified ultraviolet wavelengths: longwave and shortwave.

The process X is cellular respiration. It involves the use of oxygen to break down a monosaccharide to produce ATP and ADP.

The metabolic processes taking place in a plant cell are shown in the image in the question. We are supposed to identify;

The process Y and the organelle where it occursThe molecule Z The process X

Firstly, let us recall that the process X involves the combination of carbon dioxide and water to produce a monosaccharide. This is the process of photosynthesis and it occurs in the chloroplasts.

When there is a high level of glucose in the body, the molecule acetyl co-A(molecule Z) could be converted into triglycerides. The process X involves the use of oxygen to break down a monosaccharide to produce ATP and ADP. The process involved is cellular respiration.

Which statement describes the way the paramecium reproduces asexually
A,it happens by cell division that include mitosis.
B,it happens by the formation of gametes.
C,it happens by cell division that include meiosis.
D.it happens by fertilization of an egg by sperm.

Answers

The statement that describes the way the paramecium reproduces asexually is as follows: it happens by cell division that include mitosis (option A).

What is asexual reproduction?

Asexual reproduction is one of the two types of reproduction that involves neither meiosis nor fusion of gametes.

This means that in asexual reproduction, new offsprings are produced by a single parent. The new individuals produced are genetically and physically identical to each other i.e., they are the clones of their parents.

This is possible because the single parent cell divides mitotically to produce identical daughter cells.

Therefore, option A is correct regarding the way paramecium reproduces asexually.

the genes stc1 and stc2, which share a common ancestor, are found in both zebrafish and humans. all four stc genes display similar patterns of exon and intron sequences. based on these facts, what is the most likely explanation for the origin of stc genes?

Answers

Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.

We can arrive at this answer because:

Despite having exons, prokaryotes do not have introns in their genomes.This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.

This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.

Which researcher theorized that hypnosis comes about as a form of roleplay between hypnotist and subject? A. Ernest Hilgard B. Theodore Sarbin C. Theodore Barber D. Milton Erickson Please select the best answer from the choices provided A B C D

Answers

Answer:

Hey, your answer should be D

Explanation:

Good luck friends

The researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D. Milton Erickson was a famous American psychiatrist and psychotherapist.

What is Milton Erickson?

He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.

Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.

A running back is running down the field and two people on the opposing team run towards him. One person is running east with a force of 250 N. The other person is running west with 250 N of force . They all collide at the same time. Show the forces affecting the running back.

Are the forces balanced or unbalanced?

Net force = ?

Answers

Given our understanding of the laws of physics, we can confirm that the Net force affecting the running back (ignoring gravity and its complementary force) is that of 500N and balanced.

In physics, we can say that the net forces being applied to an object are balanced when the forces are

Equal in sizeApplied in opposite directionsApplied at the same time.

The question states that the running back collides with two members of the opposing team at the same time. This, coupled with the fact that the opposing team members are described to arrive on exactly opposite sides, we can say that the forces being applied to the running back are indeed balanced.

Furthermore, since the forces are 250N in size each, we can confirm that the net force applied to the running back is 500N. To this, we would normally add the force of gravity, however, in order to do this, we would need the weight of the running back, that is, data that is not provided.

The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.

Answers

Answer:

Explanation:

The  primary purpose of the  systemic  circuit is for blood to release carbon dioxide and pick up oxygen

The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.

What is pulmonary system?

It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.

Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.

The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.

The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.

The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.

This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.

Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.
