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

Answer 1

Answer: 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.

How is the DNA code itself a homology?

Answers

Answer:

Explanation:

These fundamental similarities are most easily explained by evolutionary theory: life shares a common ancestor. ... In fact, the DNA code itself is a homology that links all life on Earth to a common ancestor. DNA and RNA possess a simple four-base code that provides the recipe for all living things.

A test cross with an organism with a homozygous recessive genotyperesults in 50% of the offspring exhibiting the recessive trait.
What is the genotype of the test-cross
parent?
I. Homozygous recessive
II. Homozygous dominant
III. Heterozygous
A. I only
B. II only
C. III only
D. I or III
E. II or III

Answers

The answer is heterozygous.

If it was crossed with homozygous dominant, then 100% of the offspring would show the dominiant trait. If it was homozygous recessive 100% of the offspring would have the recessive trait

I say C. III ONLY, because if you put this all out on a punnet chart that is the only one that comes out with a correct outcome, 50%, so I say it is heterozygous only, answer choice C!

Hope this helps, if not, comment below please!!!!

Which explanation is most likely the reason for the evolution of a larger brain in humans?The size of the human brain increases the more it is used.
A larger brain allows humans to solve complex problems.
The size of the human brain has changed randomly over time due to mutations.
A large brain increases humans’ ability to fight and survive disease.

Answers

The most likely reason for the evolution of a larger brain in humans is that the size of the human brain increases the more it is used. The correct option is A. Evolution findings show that as the activities of man increase and as he advance in using his brain to develop new things that are needed for his convenience, the brain size also continues to increase.

Answer:

A large brain allows humans to solve complex problems.

Explanation:

The large brain in humans has enabled them to solve a complex problem in of the real world and also enabled them to survive more as compared to humans with the smaller brains.

In seven million years the size of the human brain is tripled. That allows them to store and process a huge amount of information and also help to interact with the people in the surrounding better.

Hence, the correct answer would be option B.

Which of the following best describes half-life?a. Half the time it takes for all of the nuclei in a sample of a radioactive isotope to decay.
b. The time it takes for the nucleus of one atom of a radioactive isotope to split in half.
c. The time it takes for half of the nuclei in a sample of a radioactive isotope to decay.
d. The time it takes for the nucleus of one atom of a radioactive isotope to decay.

Answers

The time it takes for the nucleus of one atom of a radioactive isotope to split in half is half life.

The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.

What is radioactive isotope?

An unstable form of a chemical element that releases radiation as it breaks down and becomes more stable.
Radioisotopes may occur in nature or be made in a laboratory. In medicine, they are used in imaging tests and in treatment.
These are also called radionuclide.
