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.

Bat echolocation calls vary in their dominant frequency approximately between 11 kHz (e.g. Euderma maculatum; Fullard & Dawson 1997) and 212 kHz (Cloeotis percivali; Fenton & Bell 1981). Most insectivorous bats call with dominant frequencies between 20 kHz and 60 kH

The only word among the available words that do not fit the pattern would be temperature.

Ash, dissolved gases, and silica content are similar in the way that all of them are made up of matter.

Matter refers to any substance with weight and is able to occupy space. Ash is made from solid particles. dissolved gases are gases, and silica contents are also from solids.

Temperature, on the other hand, is a scalar quantity. It is not something that can be held or seen. It has no weight and neither does it occupy space.

All members of a species that dwell in the same region are referred to as a population. You are a member of your hometown's human population. A freshwater pond is home to a variety of species, including mallard ducks and cattail plants growing on the pond's border. Basically, a population is a collection of individuals of the same species that live in the same geographic region and interbreed. Many animals have several populations that are spread across a wide range of geographic locations.

The information provided is NOT sufficient to indicate if the TACGTGGACTGAGGACTCCTC sequence is a 'sense' strand or 'antisense' strand.

DNA is a double helix molecule composed of two long chains of nucleotides linked by hydrogen bonds.

During transcription, the sense DNA strand is actively used as template to produce a complementary RNA molecule.

In consequence, it is required to know the sequence of the resulting RNA to determine if the sequence above belongs to a 'sense' strand or 'antisense' strand.

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.

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.

Answer:

Many see RNA editing as an important alternative to DNA editing using techniques such as CRISPR.

Explanation:

It is beneficial for scientists to understand how other organisms are able to edit their RNA because it gives an idea for scientists in order to identify particular causes and symptoms of genetic and environmental disorders among individuals.

RNA stands for ribonucleic acid. It may be characterized as a type of nucleic acid that is significantly present in all living cells. It expresses some structural and functional similarities to DNA. There are major three types of RNAs found. It includes mRNA, tRNA, and rRNA.

There are various techniques that help scientists to observe numerous RNA and its editing in organisms. It is an important alternative to DNA editing. This methodology of RNA editing and functionality is determined by using techniques such as CRISPR.

Therefore, it is beneficial for scientists to understand how other organisms are able to edit their RNA because it gives an idea for scientists in order to identify particular causes and symptoms of genetic and environmental disorders among individuals.

We can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.

Darwin noticed that each of these species were very similar, but possessed slightly different traits. These traits seem to perfectly fit the needs of each species for their specific island, leading to his creating the theory of evolution through natural selection.

Therefore, we can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.

Answer:

Why is angiogenesis important in cancer? Angiogenesis plays a critical role in the growth of cancer because solid tumors need a blood supply if they are to grow beyond a few millimeters in size. Tumors can actually cause this blood supply to form by giving off chemical signals that stimulate angiogenesis.

The selenium particles when coated on paper towels were extremely effective and continuously inhibited (about a 90% reduction) the growth of gram-positive bacteria including S. aureus and S. epidermidis after 24, 48, or 72 hours.

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.

Explanation:

There are essentially two ways of solving nuclear half-life problems. One way is by applying the half-life formula, which is

A

=

⋅

(

)

t

t

- the quantity that remains and has not yet decayed after a time t;

A

- the initial quantity of the substance that will decay;

t

- the half-life of the decaying quantity;

In this case, the rock contains

1/4th

of the orignal amount of potassium-40, which means

Therefore,

A quicker way to solve this problem is by recognizing that the initial amount of the substance you have is halved with the passing of each half-life, or
