(Q005) Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today

Answers

Answer:

Lactose tolerance conferred an evolutionary advantage, thereby this beneficial mutation increased its frequency in the population

Explanation:

Originally, adults were unable to digest lactose. But approximately 8,000-10,000 years ago something remarkable happened: a mutation near the gene that produces the lactase enzyme appeared in a raising cattle population from Europe-Middle East, making adults able to digest lactose. Nowadays, many adults from different societies are tolerant to digest lactose because this mutation increased its frequency and extended to different populations. It is a classical example of how a beneficial mutation may eventually become the most common gene variant by increasing its frequency in the population, and, subsequently extending to other populations. It is possible to hypothesize that new mutations associated with human activities may appear in current human societies, thereby conferring an evolutionary advantage in the same way that lactose tolerance in cattle-raising people. For example, nowadays, mutations in human behavior-associated genes might confer beneficial social skills (thereby increasing the frequencies across time or across populations).

How do bacteria help plants grow?

They break down carbon dioxide into carbon and oxygen.
They protect plants from pollution from acid rain and hydrocarbons.
They change ammonia into nitrogen gas for plants to use to make proteins.
They change nitrogen into nitrates plants use to make proteins.

Answers

Answer:

They change nitrogen gas  into nitrates for plants to make proteins.

Explanation:

Nitrifying bacteria and Nitrogen-fixing bacteria work together to convert nitrogen gas into nitrates which plants use to make DNA, RNA, and amino acids (which are used to make other proteins).

Bacteria help to plant growth by changing nitrogen (N element) into nitrates plants use to make proteins.

How do bacteria help plant growth?

Bacteria help to plant growth by helping nitrogen assimilation during different metabolic processes.

This nitrogen is fundamental to synthesizing proteins, which are mainly composed of this element.

In conclusion, bacteria help to plant growth by changing nitrogen (N element) into nitrates plants use to make proteins.

Describe how dawin's theroy of evolution by natural selection can explain the spread of antibiotic-resistant microorganisms which caused the return of Latasha's strep throat

Answers

EXPLANATION:-

Since there was already an anti resistant microorganisms that actuallly have been able to survive through the antibiotics, natural selection states that if one survives and is well adapted to a certain environment, then offspring from that survivor will be created and beneficial traits for the offspring will be received having them a chance for survival. So, the microorganisms spread and spread offspring with that anti resistance in which is the Survival of the Fittest. Until there are no microorganisms that aren’t resistant the lastahas strep throat then returns.

Answer:

C. There is not enough oxygen in the

atmosphere to support excessive numbers of

aquatic plants.

Explanation:

n excess amounts, both nutrients can cause an increase in aquatic plant growth and algae blooms, called eutrophication. These algae blooms live at the water surface, in order to easily access oxygen and sunlight. As a result, eutrophication prevents lower water levels from access to sunlight and oxygen in the air.

1. Mitochondria, because they rely on the ER as an energy source
2.Ribosomes, because they receive proteins made by the ER
3.Golgi apparatus, because n packages proteins received from the ER
4.Cytoplasm, because it relies on the ER for structural support​

Answers

Answer:

3.Golgi apparatus, because n packages proteins received from the ER

Explanation:

1. Mitochondria, because they rely on the ER as an energy source  - this is false. The mitochondria are the energy-producing organelles in the cell. They do not rely on the ER for energy

2.Ribosomes, because they receive proteins made by the ER  - this is false, the ribosomes are the protein synthesis factories of the cell. Some of them are even attached to the ER

3.Golgi apparatus, because n packages proteins received from the ER  - this is true. The ER is involved in folding and modifying proteins, which are passed to the Golgi for further modification and transport.

4.Cytoplasm, because it relies on the ER for structural support​  - this is false, structural support is provided by the cytoskeleton

Which best describes the nucleus of an atom?
a. It is thee negatively charged part of the atom
b. It contains no mass.
c. it is made of neutrons and electrons.
d. It is the most massive part of the atom

Answers

Answer:

The answer is D.

I used the process of elimination to find your answer if you want to understand further look in my explanation. I hope I can help! Have a great day!

Explanation:

So the negatively charged part of a atom is the electron cloud so A is wrong because it would be in the wrong spot. Plus the nucleus is positively charged because it contaims only protons ans neutrons. Neutrons are neutral and protons are positive so the protons over power the nuetrons. Therefore the nucleus is not made of neutrons and electrons so C is wrong. And B is also wromg because the nucleus does indeed have mass. So the correct answer is D, it is the most massibe part of a atom.

what chemical reaction takes place between an egg shell and vinegar ?

Answers

Answer:

The reaction of the eggshell in vinegar is an acid-base reaction. When you submerge an egg in vinegar, the shell dissolves, leaving the inner semi-permeable membrane intact. Vinegar (acid) breaks apart the solid calcium carbonate crystals (base) in the eggshell into their calcium and carbonate parts.
