List and describe three points of evidence for the Big Bang theory

Biology
1 answer:
Serjik [45]3 years ago
3 0

Answer:

1. Microwave Background  - Very early in its history, the whole Universe was very hot. As it expanded, this heat left behind a "glow" that fills the entire Universe. The Big Bang theory not only predicts that this glow should exist, but that it should be visible as microwaves - part of the Electromagnetic Spectrum.  This is the Cosmic Microwave Background which has been accurately measured by orbiting detectors, and is very good evidence that the Big Bang theory is correct.

2. Redshift of Galaxies  - The redshift of distant galaxies means that the Universe is probably expanding. If we then go back far enough in time, everything must have been squashed together into a tiny dot. The rapid eruption from this tiny dot was the Big Bang.

3. Mixture of Elements  - As the Universe expanded and cooled down, some of the elements that we see today were created. The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right.

Sunny_sXe [5.5K]

Answer:

B) Viruses are killing some of his B cells and becoming incorporated into the genomes of others.

Explanation:

Epstein-Barr virus causes infectious mononucleosis by following mechanism.

1) Epstein-Barr virus attaches to and infects epithelium of the throat where it replicates and causes pharyngitis.

2) Virions enter the lymphoid vessels and are carried to the lymph nodes. Some virions escape the lymphnode trap and are carried to the bloodstream.

3) Virions attach specifically to B lymphocytes and infect them, producing either latent infection or productive infection.

4)The infected B lymphocytes actively replicate and differentiate into cells producing random immunoglobulins.

5)T cells respond to infection and destroy the lymphocytes replicating EBV vitus.

6) Latently infected B lymphocytes become immortal. They are not attacked by T cells.

The bottleneck effect is used to describe an event where a population decreases. One example involves the northern elephant seal
Svet_ta [14]
I think the best phrase to describe this would be Founder effects. Founder effects occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have; a non-random sample of genes in the original population. Reduced variation from the original population.. According to Bottlenecks and founder effects, genetic drift can cause big losses of genetic variation for small populations.

aev [14]

Answer:

Answer:

B. only chemoreceptors,

mechanoreceptors, thermoreceptors, and

nociceptors

Explanation:

Receptors are chemical structures, that

receive and transduce signals that may

be integrated into biological systems.

Receptors that can be found in the

mouth include: chemoreceptors,

mechanoreceptors, thermoreceptors, and

nociceptors.

Chemoreceptors

These are receptors that detects

chemical stimuli, either molecules or ions

dissolved in liquids. An example would

be our taste buds in the mouth, because

they respond to specific molecules or

ions in our ingested food.

Thermoreceptors responds to changes

in temperature. These receptors are

present in the oral cavity, skin and

hypothalamus.

Mechanoreceptors are receptors that

respond to distortion of the plasma

membrane that occurs due to touch,

pressure, vibration, stretch, stress or

strain

. They can be found in the mucosae of

hypothalamus.

Mechanoreceptors are receptors that

respond to distortion of the plasma

membrane that occurs due to touch,

pressure, vibration, stretch, stress or

strain

. They can be found in the mucosae of

ginviva (gum), cheek, tongue and soft and

hard palate.

Nociceptors are receptor responds

to painful stimuli. The purpose of

nociceptors is to inform the body of

injury, damage or threat of damage to

body tissues so that a response may be

made. They can be found in the tooth

pulp and within dentine cavity.
