essay on atoms molecules and matter

Answers

Answer 1

Answer:

Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.

H20 is a molecule, N2 is a molecule even O3 is a molecule.

Matter is basically anything that takes up space and that has mass. All physical objects have matter. The original stated of matter are solid, Liquid, And gas.

What is DNA fingerprinting?

The technique of identifying a person's DNA traits is called DNA profiling. DNA barcoding is a type of DNA analysis used to identify species rather than specific individuals. The nucleotide sequences of specific areas of human DNA that are particular to each person are utilized in the laboratory procedure known as DNA fingerprinting to ascertain a person's likely identification.

DNA fingerprinting is a method for detecting and analysing individual DNA variations. It is based on polymorphism and variability in DNA sequences. Applications of it include: It is utilized in forensic science to pinpoint potential criminal offenders. to establish family relationships and establish paternity.

why do translocation sometimes reduces the total number of chromosomes

Answers

Answer:

When two nonhomologous chromosomes mutate by exchanging parts, the resulting chromosomal rearrangements are translocations. Here we consider reciprocal translocations, the most common type. A segment from one chromosome is exchanged with a segment from another nonhomologous one, so two translocation chromosomes are generated simultaneously.

How do moon jellies obtain energy?

Answers

Answer:

Like all true jellies, the moon jelly's tentacles are covered with specialized stinging cells, called cnidocytes. ... They have very little nutritional value, however, so the predators that specialize on them must eat hundreds and hundreds of these jellies in order to maintain their required energy levels. Moon jellies stay close to shore, and they pulse their bell to keep themselves near the surface, with their tentacles pointed down. This ensures they can gather as much food as possible. They gather food when it gets stuck in the mucus along the bottom of the bell.

Hope this helps <3 PMB (plz mark brainliest)

Answer:

While it might be nice to grow the missing part back, doing so takes a lot of energy that simply may not be available. For the moon jelly, it takes less energy to simply rearrange the parts in its gelatinous body into a new symmetrical and hydrodynamically efficient configuration and keep moving along on its journey.

As you walk down the hall on the way to class, several students sneeze. You unknowingly inhale some of the droplets
that were expelled when they sneezed, allowing the flu virus to enter your body. Explain the nonspecific immune
defenses that the virus must bypass in order to infect a body cell. (5 points)

Answers

Answer:

The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body. The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs. 

The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera. Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.

The antiviral defense is composed of changes in cells that prevent viral replication and increase susceptibility to death by lymphocytes.

What innate defense mechanism against viruses?

Viral replication interferes with protein synthesis and cell function and leads to injury and death of the infected cell. The main mechanisms of innate immunity against viruses are inhibition of type I interferon infection and NK cell-mediated destruction of infected cells.

With this information, we can conclude that the antiviral defense is composed of alterations in the cells that prevent viral replication and increase the susceptibility to death by lymphocytes, thus eliminating the reservoirs of viral infection.

Lloyd’s lab partner is looking down into a test tube while he heats the contents by using a flame. Which action should Lloyd recommend to his partner if heating must continue?
Wear safety goggles while looking into the opening of the test tube.
Cover the opening of the test tube so that no materials can boil out of it.
Move the test tube so that the opening is pointing away from all students.
Put the test tube in a hot water bath so that no water can enter its opening.

Answers

The correct action that Lloyd should recommend to his partner who was looking down into the test tube if heating must continue would be to move the test tube so that the opening is pointing away from all students.

Wearing safety goggles (and looking directly down at the test tube) might not be enough to protect Lloyd's partner nor other students in case the content of the test tube splashes out.Covering the test tube might hinder any generated gas as a result of heating from escaping safely into the air and this might cause an explosion.Putting the test tube in a hot water bath so that water can enter its opening will definitely affect the reaction and prevent them from getting accurate results/observations.

Hence, the most correct action would be for Lloyd's partner to move the test tube so that the opening is pointing away from all students.

How is the Nucleus like a brain?

Answers

Answer:

The nucleus contains the DNA of the cell which can be thought of as the brain of the cell.

The nucleus responds to stimuli via receptors which can be primary or secondary. Basically, an external ligand (hormone, protein, nutrient, etc) binds to the surface receptor of a cell, this, in turn, causes the receptor to release a messenger (most of the time circular AMP (cAMP)) which binds to a secondary receptor which is either directly inside the nucleus or on the nuclear envelope. Finally. the portion of the DNA which is responsible for the protein to respond to the ligand is activated and begins transcription.

The activated DNA section (gene) produces mRNA which in turn produces a protein in response to the ligand.

On top of this, the entire cell cycle of rest, growth, and division is controlled by the nucleus.

a essay explaining why i choose a certain university​

Answers

Answer:

Because the facilities here for my subject are second to none” – this shows that your subject has been at the forefront of your mind when making a sensible choice of university, again demonstrating your level of commitment to it. You can mention specific facilities to show that you’ve read into it thoroughly.

“Because I liked the approach this university takes to my course” – even within the same subject, every university takes a slightly different approach to the way it’s taught and structured. The university question is another good opportunity to show that you’ve really thought about the course and gone to the effort of finding a university whose approach to the subject you agree with. You can even name specific modules that set this university’s course apart from the others offering the same subject.

Along similar lines, you could also mention the university’s great reputation for your subject, or the presence of certain lecturers you feel inspired by (though don’t let this last point dominate your answer; lecturers often move about or go on sabbatical, so even if there’s a particular academic you admire, they may not end up teaching you).
