Answer:
All living things share a common code-DNA
Explanation:
Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.
According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

Answer is B
Explanation : Plant cells are enclosed by a rigid cell wall. When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. ... This liquid or hydrostatic pressure called the turgor pressure prevents further net intake of water .

Where could the instructions be held to create a protein?
Answer:
The correct answer is - in DNA molecules.
Explanation:
The instructions or the information for the creation of the protein is held in the DNA molecule inside the nucleus in eukaryotic organisms while present in the cytoplasm in prokaryotes.
The DNA molecule has coded all the information for the particular protein by the two processes transcription and translation. Transcription is the first step which makes a copy of the DNA is complementary in the form of mRNA, The second step involves the decoding mRNA into an amino acid chain with the help of ribosomes.

What are some ways another kind of natural disaster could change an environment and change the selective pressures felt by a species?
Answer:
Strong volcanic eruptions and fires can temporarily change regional weather, cooling or heating the air, changing winds, or causing rain. Volcanoes, storms, and floods can kill marine animals directly, or cause long-term problems by depositing debris and affecting the temperature and salinity of water.
Explanation:
Some ways through which natural disasters could change an environment and change the selective pressure felt by a species are volcanic eruptions, wildfires, floods, droughts, storms, acid rain, etc.
What is Species?Species may be defined as the collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. It is the basic unit of classification and a taxonomic rank of an organism.
According to the context of this question, effective and long-lasting volcanic eruptions and fires can significantly change regional weather. Apart from this, actions like cooling or heating the air, and alterations in wind patterns and directions that typically cause rain also change an environment and change the selective pressure felt by a species.
Therefore, some ways through which natural disasters could change an environment and change the selective pressure felt by a species are volcanic eruptions, wildfires, floods, droughts, storms, acid rain, etc.

What methods of dating do scientist use to study Earth's history? (Two part answer)
Short answer: To lower the price of oil and reduce dependence on foreign imports, a federal government is debating whether to open large stretches of its coastline to domestic drilling. Evaluate this plan in terms of two ecosystem services that the country might gain and two services the country might lose if the coastline is opened for drilling. In your answer, be sure to explain how a perceived negative externality might become an internal cost.
Answer:
This drilling enhances economy of the country but at the same time disturbs aquatic animals.
Explanation:
Due to drilling at coastline, oil should be extracted from the sea which fulfills the oil requirement of the country and valuable money can earned by exporting this oil. Due to this drilling, the habitat of aquatic animals are destroyed and no trade should be done from this coastline with other countries because the area is now only for drilling. So this plans has both positive effect on the country's economy but has negative impacts on the environment and ecosystem.

Describe the role of fermentation in maintaining ATP and NAD+ levels
Answer:
Please find the description of the role of fermentation in the production of ATP and NAD+ levels below.
Explanation:
Fermentation is a form of anaerobic respiration in which glucose is broken down in the absence of oxygen to produce carbon dioxide and alcohol or lactic acid depending on which type of fermentation it is.
Fermentation process makes use of the electron carrier, NADH, mad oxidizes it back to NAD+. This electron acceptor molecule is strictly required in the glycolysis process. Hence, fermentation helps convert NADH to NAD+ needed by glycolysis for the production of few ATP molecules. In summary, fermentation may not directly synthesize ATP but it helps produce the molecule (NAD+) needed to synthesize it.
What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.
Answer: Fearful and worried posture
Explanation:
Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.
When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).
All these tell that a dog is scared and worried or feeling tense.
Answer:
Defensive Threat Posture
Explanation:
Whale eye (whites of eyes showing)
Tail down or fully tucked
Piloerection
Ears back or flatten against head
Pupils dilated
Corners of mouth pulled back
Body lowered
Body leaning backward
A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

93 million miles.
A unit of distance equal to the size of the Milky Way Galaxy or 100,000
light years across
D)
A unit of time that is equal to the amount of time it takes light to travel
from the Sun to Earth,
Answer:
B
Explanation:
The correct option should be B.
The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.
Mathematically, in astronomy,
1 astronomical unit = 150,000,000 km
But then, 1 km = 0.621371 mile
Hence,
150,000,000 km = 150,000,000 x 0.621371 miles
≈93,000,000 miles
Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.
The correct option is B
