What are the four features of minerals? (use complete sentences and your own words.)
(NO LINKS PLEASE)
Answer:
1)All minerals are naturally occuring.
2)They have to have a crystalline structure and a definite chemical composition.
3)They are inorganic.
4)They are a solid.
Explanation:
1-You have to find a mineral in the nature. It cannot be created in a lab.
2-Crystallline structure is the ordered arrangement of ions, molecules, or atoms in an object.
3-Inorganic means that the object has not bonded with carbon.
4-Solid means that it is not fluid and is hard and stable.

Which cells are eukaryotic?
a. Bacterial cells
b. Animal and plant cells
( it’s b )
Answer:
B . Animal and plant cells
Animal and plant cells are eukaryotic cells.
What are Eukaryotic cells?The region One of the three realms of life is eukaryote; the other two are bacteria and archaea.Organelles that are membrane-bound and found in eukaryotic cells include the nucleus, mitochondria, and endoplasmic reticulum. Protozoa, fungi, plants, and animals are examples of eukaryotic cell-based organisms. The biological domain Eukaryote is where these species are categorized.Animals, fungi, protists, and plants are eukaryotic cells examples. They have chromosomes, which organize their genetic material.Since prokaryotic cells lack a membrane-bound nucleus, eukaryotic cells are the main difference between these two types of creatures.

which of the following best explains why top predators can have up to 60 times as much of persistent organic pollutants as their prey and up to 600 times as much of the pollutants as producers ?
This is because persistent organic pollutants accumulate in the body fat of living organisms and increase in concentration as they move up the food chain.
What is Persistent organic pollutants?These are organic compounds that are stable and do not degrade easily. They are usually harmful and accumulate in the body fat of organisms.
They are also known to increase in concentration as they move up the food chain which is why predators have more of them.

Environmental resistance includes
biotic/abiotic factors that are
to life.
Answer:
The environmental resistance factors are all the factors or things that keep a population of the organisms from endlessly increasing i.e. keep a check on it. . They reduce the chances for reproduction, affect the health of organisms/individuals, and raise the death rate in the population.
The environmental resistance factors include the factors that are biotic and abiotic.
• The biotic factors are things like a predation, a parasitism, lack of food, competition with other organisms and disease.
• Abiotic factors include factors like drought, fire, temperature, and even the wrong amount of sunlight could affect it.

Brown hair is dominant and blonde hair is recessive.
The parents have the following alleles.
Bb
Bb
What color hair do the parents have?
A. One has blonde and the other has brown
B. Brown
C. Blonde
d. unable to determine
Given what we know, we can confirm that the parents have brown hair.
This has to do with how dominant alleles work. When an allele is dominant, it is because, in the presence of mixed alleles, this trait will always be the one reflected in the phenotype of the individual. Since the parents possess an allele for brown hair and one for blonde, but brown hair is dominant, both parents will have brown hair.
Therefore, we can confirm that both parents will have brown hair due to the dominant nature of the brown hair allele.

One person consumes the equivalent of five cows per year. Five cows consume a total of 39 million Calories of vegetation per year. One person only needs one million Calories a year to survive. Which statement best describes the efficiency of energy transfer in this scenario?
It is very efficient because the person can eat less.
It is inefficient because less energy is needed at the top.
It is very efficient because most energy is made by producers
Only a portion of energy from vegetation makes it to a person.
Answer:
It is very efficient because the person can eat less.
Explanation:
the common knowledge answer
Only a portion of energy from vegetation makes it to a person. The correct option is D.
What is energy efficiency?The definition of energy efficiency is the use of less energy to carry out a task or achieve a goal.
Ecological efficiencies at each trophic link determine the food chain efficiency (FCE), which is calculated as the percentage of energy fixed by primary producers that is transmitted to the top trophic level.
The energy supply accessible to trophic level N+1 divided by the energy used by trophic level N is the definition of ecological efficiency.
Only a percentage of the energy from vegetation makes it to a person, which best sums up the efficiency of energy transmission in this situation.
Thus, the correct option is D.
