All of the following are sources of air pollution, EXCEPTA) chlorofluorocarbons (CFCs).
B) heavy metals such as mercury.
C) nitrogen oxides from automotive exhaust.
D) small particles of smoke and dust in smog.

Answers

The correct answer is B) Heavy metals such as mercury.

Explanation:

Heavy metals such as mercury or lead are denser than regular metals, this causes it is common for these metals to be found in the surface of Earth rather than in the air or atmosphere. Indeed, mercury and other similar metals are extracted from the Earth's crust and then used for different purposes. As a result of this, mercury ends up in the surface of Earth or in water sources which causes soil or water pollution. This means mercury is not a common source of air pollution; on the opposite other such as CFCs, nitrogen oxides and smog remain in the air and therefore are sources of air pollution.
B is the correct answer.

As an infant, Maya had to have part of her brain removed due to a life-threatening medical problem. Eighteen years later she graduated from high school as the valedictorian of her class, was awarded a college scholarship, and showed no deficits as a result of the brain surgery. The fact that her brain was able to adapt and rewire itself following the operation is called ___________________.a) Synaptic Potentiation
b) Trans-Cerebral Restructuring
c) Post-Traumatic Cerebral Malleation
d) Neuroplasticity

Answers

Answer:

D

Explanation:

Brain can create new connection between neurons.

Final answer:

The ability of the brain to adapt and compensate for damage by forming new connections among remaining neurons is called Neuroplasticity. Despite having part of her brain removed as an infant, Maya exhibited this through her high school graduation, scholarship award, and absence of deficits from the surgery.

Explanation:

The ability of Maya's brain to adapt and rewire itself after a part of it was removed is known as Neuroplasticity. The term neuroplasticity refers to the brain's incredible capacity to reorganize itself, developing new connections among remaining neurons when part of it gets damaged or removed, thus minimizing the deficits of such loss.

In Maya's case, she demonstrated impressive neuroplasticity because, despite having part of her brain removed as an infant due to a life-threatening medical problem, she graduated from high school as the valedictorian of her class, was awarded a college scholarship, and showed no deficits as a result of the brain surgery. Hence, it's worthwhile to emphasize the power of neuroplasticity in our amazing brain.

How has the concept of a "planet" changed since the 16th century? Do you think this shows scientific accuracy or disproves future facts, as one assumes that they will be discredited in time too?

Answers

Science keeps "improving", so the scientific theories and ideas from the past are either expanded on or proved to be false. The concept of planets has definitely seen changes, with Pluto peven being considered not a planet. In the 20 century we believed there were 9 planets but now there is considered to be 8. Science exists as it is but as humans we are constantly discovering more of it because of improvement in the times and technology. Science that proves to be accurate will never be discredited though it will be improved upon .

Answer:

\/

Explanation:

In the 16th century everyone thought everything revolved around the Earth. It wasn’t till the 17th century that everyone got it right that everything revolved around the Sun. I think both as we get better at understanding things our world becomes bigger and everything could change. One day we could find something different and the next day it will be totally different.

Specialized cells are formed when cells differentiate.
a. True
b. False?

Answers

Specialized cells are formed when cells differentiate - this is true. When you have stem cells, you're talking about undiferentiated cells with no specific roles in the body. When these cells start differentiating and assuming different roles, they are also becoming specialized.

Which of these is a segment of DNA that contains the information necessary to produce a protein?

Answers

Answer;

Gene

Explanation;

  • A gene is a functional unit of a DNA molecule, it is a segment of DNA that contains the information that is used to generate proteins. Each gene codes for a particular protein or in other words is used to produce a specific protein via the processes of transcription and translation.
  • By coding for a given protein, gene determines the traits or characteristics of an individual. During the process of transcription, a process catalyzed by enzyme RNA polymerase, a gene is use to generate a messenger RNA, which then undergoes the process of translation in the cytoplasm to form proteins.

The answer is C) gene.
