what describes a natural gas
Answer:
Explanation:
Natural Gas. Mixture of hydrocarbon gases that occurs with petroleum deposits, principally methane together with carying quantities of ethane, propane, butane, and other gases. Used as fuel in the manufacture of organic compounds. Where is natural gas found? Found in reservoirs underneath the earth's surface.
How are gene and protein sequences used to classify organisms?
Answer:
"Genes code for proteins and each organism has different genes."
Explanation:
"Sequences of genes are used to identify differences and similarities between organisms. So it can be used to identify related organisms, because they show differences between species.
DNA acts as set of instructions for building an organism, because it contains the genetic instructions to make for proteins. Genes are made of DNA and each one codes for a different protein. In that way, different types of organisms can all be differentiated through their genes.
This is because the translation of proteins from DNA is guided by a universal code. It means, the same codons codes for the same amino acid across all species."
What is the role of complementary base pairing in the replication of DNA?
A It reduces the number of errors in the process of DNA replication.
B It introduces more hydrogen bonds between the nucleotides.
C It ensures that the replicated DNA is an exact copy of the parent DNA.
D It allows the replicated DNA to have a different nucleotide arrangement
Answer:
c. it ensures that the replicated DNA is an exact copy of the parent DNA
Explanation:
This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
This is the original strand of DNA: ATG AAG TTT GGC TAA
Which option would represent a frame shift mutation due to deletion during replication?
Answer:
ATG AAG TTG GCT AA
Explanation:
I took the test
A genetic modification in which there is an acquisition and omission of nucleotide base in the series is called frame-shift mutation.
It modifies the reading frame of the series that can vary the amino acid sequences and the protein that it forms.
The correct answer is:
ATG AAG TTG GCT AA
This can be explained as:
In the sequence given in the question ATG AAG TTT GGC TAA there is a deletion mutation in the Thymine (T) nucleotide.The deletion of thymine (T) causes the reading frame of the three-nucleotide to change and the reading pattern gets altered.The frame now changes and the reading will start with altered three base pairs.So, the sequence ATG AAG TTT GGC TAA will be mutated to ATG AAG TTG GCT AA.

What are the 3 types of plate boundaries? Describe each.
Explanation:
Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Convergent boundaries -- where crust is destroyed as one plate dives under another.
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

In which situation would artificial insemination most likely be used over other forms of treatment?
Artificial insemination can be used when there is a case of infertility.
This process lets the sperm skip the cervical mucus entirely . doctors often use this process when the reason for the couple’s infertility is unclear.
In case of endometriosis, this process is helpful in mild or moderate cases of endometriosis.
During cellular respiration, organisms convert different kinds of food into glucose. Cells then break down the glucose to provide energy for life activities. Which of these substances is also produced during cellular respiration?
A. Carbon dioxide
B. Fat
C. Oxygen
D. Protein
Fat, of these substances is also produced during cellular respiration. Thus, option (b) is correct.
What is respiration?Respiration is the transmission of oxygen from the outside world to cells within tissue, as well as the elimination of carbon dioxide in the reverse direction. It is a physiological reaction that occurs within living creatures' cells. We can breathe because of our lungs and respiratory system.
Glycerol is converted into one of the intermediates of glycolysis and hence enters the aerobic respiration pathway. Fats are a fuel for cellular respiration. It provides the most energy among lipids, carbs, and proteins. Fat is a triglycerides molecule.
As a result, the fat, of these substances is also produced during cellular respiration. Therefore, option (b) is correct.

Hello. Your question is incomplete. The complete question asks for the correct answer to be found based on Catalase is an essential enzyme in living beings since all cells need it.
Answer:
B. Cells only function within a specific temperature range because enzymes only function within a specific temperature range.
Explanation:
Catalase needs to be present in all cells of the living organism because it is responsible for the decomposition of hydrogen peroxide that cannot stay inside cells for long periods of time. Following this type of reasoning, we can say that it is necessary to maintain a constant temperature for the enzymes of an organism to function well because all enzymes have a specific temperature range, even catalase.
The specific temperature range determines that the enzymes will only work within that range. Therefore, an environment where the temperature is below or above that specific range, can prevent the enzyme from functioning and even cause irreversible damage to the enzyme.

In what ways are organisms influenced by the resources in their ecosystem?
Explanation:
Ecologists have found that interactions among organisms come in several different forms. In antagonistic relationships, organisms compete for resources, spread disease to their neighbors, or consume each other. In other cases, species with large structures become habitats for smaller organisms.

Pls help due today, would be greatly appreciated
Answer:
20. Genotypes is all bb, phenotype is all blue.
21. 50% TT 50% Tt genotypes, 100% tall phenotypes
Explanation:
To find the genotypes and phenotypes, we do our punnett sqaure by drawing a square, dividing it into 4 squares, putting our cross in and determining the genotypes of our offspring. Since blue eyes are recessive, they'll be represented by bb. Since tall plants are dominant, they're represented by Tt or TT. Capital letters are dominant while lowercase signifies recessive.

The formation of a new community on land that has never had organisms grow on it before is known as
Secondary succession
Rebuilding
Biomagnification
Primary succession
Answer: Primary succession
Explanation:
The formation of a new community on land that has never had organisms grow on it before is referred to as the primary succession.
Primary succession takes place when there is no ecosystem that has existed before. It should be noted that the primary ecosystem is a slow process due to the fact that it starts on bare rock. This then provides a habitat which can be colonized. An example of primary succession is when there is eruption of volcanoes.

5. How is density affected when the depth increases?
Answer:
As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.
How do final cells compare to the original cell?
Answer:
Similar in shape and chromosome number but different in size.
Explanation:
The final cells are identical in shape and chromosome number as compared to the original cell from which the new cells are formed because the original cell divided into two final cells which are identical to the original cell. The mitosis type of cell division occur in the original cell that leads to identical daughter cells which are small in size as compared to the original mature cell. The chromosome number in the new and original cells are the same i.e. diploid number of chromosome.
