Why are Wind Turbines being moved offshore?
Answer:
Wind turbines are being moved offshore because the wind comes at the right time: Offshore winds are usually higher throughout the day, allowing for more reliable and productive electricity output when market demand is highest. The majority of land-based wind resources are more efficient at night when demand for electricity is smaller.
After using a chemical mutagen to generate mutations in a dna sequence, scientists noted a mutation from c to t at the 10th position within the coding region of a gene. this mutation led to a change of proline into serine at the fourth position in the resulting peptide. using this information and the sequences listed below, select all the types of mutations that occurred.
Answer:
substitution, missense mutation, and transition
Explanation:
A mutation is any change in the genetic information of an organism. A substitution is a point mutation by which a single nucleotide base pair is replaced by a different nucleotide. Moreover, a missense mutation is a point mutation that results in the incorporation of a different amino acid in the polypeptide chain since this mutation generates a new codon which codes for a different amino acid. Finally, a transition is a point mutation where a purine (either Adenine or Guanine) is changed to another purine, or a pyrimidine (either Thymine or Cytosine) is changed to another pyrimidine (in this case, Cytosine is changed to Thymine).

Explanation:
Hope u like it
Answer:
c:ponds
Explanation:
The pons, while involved in the regulation of functions carried out by the cranial nerves it houses, works together with the medulla oblongata to serve an especially critical role in generating the respiratory rhythm of breathing. Active functioning of the pons may also be fundamental to rapid eye movement .

Which sequence shows a correct pathway for the
flow of energy in a food chain?
A) bacteria → grass → fox → owl
B) grass grasshopper → frog - snake
C) fungi - beetle → algae - mouse
D) algae → snake → duck → deer
The sequence grass → grasshopper → frog → snake shows a correct pathway for the flow of energy in a food chain (Option B).
In a food chain, primary producers (e.g., plants and algae) generate organic compounds and energy that enter into the chain.The primary consumers (e.g., herbivores) are organisms that eat primary producers.Subsequently, secondary consumers (e.g., carnivores) are organisms that eat primary consumers and so successively in all the levels.In conclusion, the sequence grass → grasshopper → frog → snake shows a correct pathway for the flow of energy in a food chain (Option B).

Why do the different genetic types of albinism result in a similar phenotype?
Answer:
Why are there different variations of albinism and why it results in the same basic phenotype?
The phenotypic heterogeneity of albinism is due to the different gene mutations affecting various points along the melanin pathway, resulting in varying degrees of decreased melanin production. Additionally, associated developmental changes occur in the optic system as a result from this hypopigmentation.

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.
how to calculate the mass of sodium atom?
Answer:
22.989769
The relative atomic mass of sodium is calculated by dividing the atomic mass of sodium by the unified atomic mass unit, which is 1.66*10-27 kg. The number of 23 amu means that a normal, or stable, sodium atom weighs 23 unified atomic mass units.

In your own words, describe how the time required for digestion can be used to determine the time of death.
Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.
Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.
Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.
However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.

Algae possess chlorophyll in their cells. They use carbon dioxide in a manner that is analogous to how we use food. Thus, option B is correct.
What is a characteristic feature of algae?By converting light energy to chemical energy through the process of photosynthesis, carbon dioxide and water are transformed into organic molecules.
Nearly all algae engage in the process, and in fact, much of what is currently known about photosynthesis was first uncovered through research on the green alga Chlorella.
Like other plants, algae benefit from sunlight, therefore denying them of it will limit or even completely stop their growth. For several days, completely shading the tank or aquarium from light is essential.
Therefore, algae require sunshine because algae can photosynthesize, or use sunlight to change carbon dioxide into biological material.

How is the ocean affected by the releasing of excess carbon?
Answer:
Explanation:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
