Answers

Answer:

A mutation that changes the first letter to 'C' is called Frameshift mutation.

Explanation:

 FRAMESHIFT MUTATION -: A frameshift mutation is a genetic mutation of a number of nucleotides caused by indels (insertions or deletions) in a DNA sequence that is not divisible by three.  A frameshift mutation (also called a framing error or a reading frame shift) The addition or deletion may alter the reading frame (the grouping of codons) due to the triplet nature of gene expression by codons resulting in a completely different translation from the root. A frameshift mutation, instead of being added or removed, is not the same as a single-nucleotide polymorphism in which a nucleotide is substituted. In general, a frameshift mutation will cause the reading of the codons to code for various amino acids after the mutation. The first stop codon ("UAA", "UGA" or "UAG") encountered in the series would also change the frameshift mutation. The polypeptide that is formed will be abnormally short or abnormally long, and most likely will not be functional.Hence, the answer is Frameshift Mutation.

Orchids are a recently evolved plant that have a novel feature known as aerial roots. What is the most likely function of an orchid's specialized roots? Aerial roots are the site of energy synthesis. Aerial roots allow the orchid to attach itself to trees. Aerial roots produce food for the orchid through photosynthesis. Aerial roots anchor the orchid to the ground.

Answers

Answer:

Aerial roots allow the orchid to attach itself to trees

Explanation:

Orchids are a group of plants that are mostly epiphytic in nature i.e. depends on other plants for physical supports. According to this question, orchids have evolved to develop a novel feature called AERIAL ROOTS.

This specialized kind of roots serves different functions in the orchid plants but however, the most likely is for PHYSICAL SUPPORT. The orchids use their developed aerial roots to climb and attach itself to their tree host in order for them to reach sunlight.

Answer:

the answer is B- Aerial roots allow the orchid to attach itself to trees.

Explanation:

Repeat the demonstration on a paved surface such as a driveway or sidewalk and document the differences. With no soil to absorb this water, what would happen in a heavy rainstorm? How would an engineer in charge of a city's flood control system prepare for the runoff generated on paved parking lots and roads in a heavy rainstorm?

Answers

Answer:

Explanation:

Without soil to absorb the excess water, a heavy rainstorm will cause massive flooding. The water will accumulate over the pavement and keep rising until it finds soil or a runoff since water always levels itself out. To prevent situations such as this one an engineer should implement drainage tunnels between the road and the sidewalks. This would allow the water to be drained and flow to the nearby body of water. This would easily prevent flooding during a heavy rainstorm.

Answer:The rate of absorption into the soil was very slow, which meant that some of the water flowed over it and was either absorbed in a different area, or ran onto the driveway and down into the street. It was a warm sunny day, so after a while the wet patch of water on the sidewalk had dried up (evaporation). Once the soil got wet from absorbing the water, the rate of absorption got even slower – like the soil was “full” – and more water ran over onto the driveway. The water on the driveway moved very quickly, since the concrete didn’t absorb it. Our street has never flooded before, but I have seen heavy rainstorms where the water was moving down the street like a big stream, carrying fallen leaves and trash down into the storm drains.

for the enzymes responsible for respiration?


Answers

Answer:

30C

Explanation:

One sign that a chemical reaction has taken place is the production of a gas. The more gas bubbles produced, the more reactions that the enzyme is catalyzing.

The highest number of gas bubbles are produced at 30C. The enzymes have the greatest activity in catalyzing chemical reactions at this temperature.

Therefore, this is the optimum temperature for the enzymes in this experiment.

C) Explain the difference in how the plant and the woman get glucose molecules to use for energy

Answers

Answer:

Ok:

Explanation:

The woman eats and digests food to get glucose while the plant can undergo photosynthesis which forms glucose.

The plant and the woman utilize different mechanisms for accumulating glucose in their body to use for energy.

What is Glucose?

Glucose may be defined as the main type of sugar in the blood which provides immediate energy to the body's tissues to perform metabolic activities.

Plants utilize the process of photosynthesis to construct their food
(glucose) with the help of carbon dioxide and water in the presence of sunlight, while the woman eats food products which are then digested into the stomach, and glucose is synthesized which is then transported into the bloodstream.

Therefore, it is well described above.

Two criteria to build the building are:

The physical geometry of the building is very important while making it. The building design should have square, hexagonal or even octagonal floor plans along with multiple slopes. The design gives strength to the building to stand in the strong winds.Use of shutters and louvers, that will restrict the entry of heat inside the building and building will remain cool.

Two constraints to build the building:

Answers

Answer:

The first box would be the pH will decrease, and the acidity will increase, and for the second box, the pH will increase, and the acidity will go down.

Explanation:

As the hydronium concentration increases, the pH decreases, and therefore if the hydromnium concentration decreases, the pH will increase. pH is sort of backwards, as the level increases, the acidity will go down, and as it decreases, the acidity will go up.

when the concentration of hydronium ions increase, the pH level decreases. because the pH is decreasing, the acidity is increasing (as anything below a 7 on the pH scale is acidic)

when the concentration decreases, the pH level increases, therefore causing it to become more basic/alkaline (acidity decreases)
