1. How did scientists discover that all living things are made of cells?

2. How did Pasteur’s experiment with the flasks help disprove the idea that living things could just appear or come from nonliving things like water and air?


3. Why are nutrients needed for living things? Describe the difference between living and nonliving things.

Answers

Answer 1

Answer:

1-Modern replica of van Leeuwenhoek's microscope. As microscopes improved, scientists made more discoveries. In 1839, two German scientists, Matthais Schleiden and Theodore Schwann, viewed plant and animal tissues under a microscope. They concluded that all plants and animals were made up of cells

2-Pasteur's experiment with the flasks helps disprove the idea that living things could just appear or come from nonliving things like water and air because the flask without a lid grew microorganisms that cam from a living thing not air or water

3-Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. ... Autotrophs are organisms that can make their own food.

the change in electrical potential that occurs when an impulse passes through a nerve cell

Answers

Answer:

The answer to this definition is: ACTION POTENTIAL

Explanation:

Action potential is a phenomenon in nervous system used to describe a change in electrical current that occurs when an impulse passes through a neuron or nerve cell. Action potential is induced when sodium (Na+) ions move from the extracellular environment into the intracellular environment.

Impulse travels across the axon of a neuron and thereby causes a difference in the electric potential i.e. - mv to + mv. This process, according to this question, whereby a change in electrical potential occurs due to the passage of an impulse through a nerve cell is termed ACTION POTENTIAL.

Calcium-41 has a half-life of 80,000 years. At the end of 240,000 years,
how much Calcium-41 would remain in a sample initially containing 60
micrograms? *
A 7.5 micrograms
B 60 micrograms
C 15 micrograms
D 30 micrograms

Answers

If the half-life is 80,000 years, then 240,000 years would be equivalent to three half-lives. In other words, the initial amount of the radioactive calcium-41 would have been reduced in half three times over. Mathematically, this can expressed as

calcium-41 remaining = initial mass of calcium-41 × (0.5)³.

Since we are given the initial mass of calcium-41, the amount of calcium-41 remaining after 240,000 years would be:

60 μg × (0.5)³ = 7.5 μg, or 7.5 micrograms.

7.5 is the answer I think hope this helps

Which type of mutation often has the least effect on organisms' traits (and may have no effect at all)? Nondisjunction Substitution Insertion Deletion

Answers

Answer:

The correct answer is - substitution.

Explanation:

Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the  DNA or RNA of an organism's genome.

In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.

If your immune system can’t actually stop you from getting ill, then why is it beneficial? Why do you think it evolved to work this way, instead of simply stopping every infection in its tracks?

Answers

Answer:

Your immune system fights off infection and disease. It has a number of ways to detect and destroy anything it recognizes as foreign to your body, including bacteria, viruses, fungi, parasites or unhealthy cells such as cancer cells. In some people, the immune system goes into overdrive, causing the body to see its own cells as foreign and attack them. This leads to what we call autoimmune diseases, such as Crohn’s disease, rheumatoid arthritis and lupus.
