Vascular tunic regulates the amount of light entering the eye.
The choroid, ciliary body, and iris form the middle layer of tissue surrounding the eye, also known as the vascular tunic or "uvea," from behind forward. The choroid occupies the bulb's posterior five-sixths and is mostly made up of blood vessels.
The vascular tunic is derived from mesoderm and is located between the outer fibrous tunic and the inner nervous tunic. The uvea is another name for the vascular tunic.
The uvea is the eye's middle layer. It is located beneath the white portion of the eye (the sclera). It is composed of the iris, the ciliary body, and the choroid. These structures regulate many eye functions, such as adjusting to different levels of light or object distances.

How do changes to genes affect the traits of an organism
Changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.
What is the significance of the genes or the traits?Changes in the genes can affect humans in several ways, such as through genetic mutations that result in changes to the regulation of gene expression and result in the addition or loss of entire genes from the organism. Not all of the genetic mutations lead to expressiable changes, but they may change the protein sequence by changing the polypeptide sequence.
Hence, changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

Tidal power
Ocean thermal energy conservation
Hydrogen fuel
Fuel cell
Energy Efficiency: give an example
Hybrids: give an example
Cogeneration
Energy conservation: give an example
Answer:
tidal power
Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Although not yet widely used, tidal energy has the potential for future electricity generation. Tides are more predictable than the wind and the sun.
Ocean thermal energy conservation
Ocean Thermal Energy Conversion (OTEC) is a marine renewable energy technology that harnesses the solar energy absorbed by the oceans to generate electric power. ... OTEC uses the ocean's warm surface water with a temperature of around 25°C (77°F) to vaporize a working fluid, which has a low-boiling point, such as ammonia.
hydrogen fuel
Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell similar to that of a battery to produce electricity, water, and small amounts of heat. Many different types of fuel cells are available for a wide range of applications
fuel cell
Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte.
Energy Efficiency
Energy efficiency simply means using less energy to perform the same task – that is, eliminating energy waste. Energy efficiency brings a variety of benefits: reducing greenhouse gas emissions, reducing demand for energy imports, and lowering our costs on a household and economy-wide level.
Hybrids
a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction.
Bovid Hybrids. Zubron - hybrid of domestic cattle and european bison
cogeneration
Cogeneration—also known as combined heat and power, distributed generation, or recycled energy—is the simultaneous production of two or more forms of energy from a single fuel source. Cogeneration power plants often operate at 50 to 70 percent higher efficiency rates than single-generation facilities

Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?
Answer:
XX
Explanation:
ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.
ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres. XX of the ACTN3 genotype will be advantageous for marathon athletes.
What is ACTN3 genotype and XX?ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance. This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.
The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.
Therefore, XX of the ACTN3 genotype is advantageous for athletes.

How does diversity in traits arise over generations? How can we determine the probability that an organism's expressed version of a trait will be passed on to its offspring?
Answer:
Diversity in traits arise over generations through mutation which cause evolution and speciation. We can determine the probability that an organism's expressed version of a trait will be passed onto its offspring through Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium helps us understand and know genotype and allele frequencies.
Through mutation, which leads to evolution and speciation, diversity in features develops over generations.
What is diversity?The variety of human distinctions that make up diversity includes, but is not limited to, racial or ethnic origin, gender, gender orientation, age, socioeconomic class, physical ability or traits, and political ideas.
Over generations, diversity in traits emerges through mutation, which causes evolution and speciation.
We can calculate the probability that an organism's expressed version of a trait will be passed on to its offspring using the Hardy-Weinberg equilibrium.
The Hardy-Weinberg equilibrium is used to explain genotype and allele frequencies.
Thus, this way, we can determine the probability that an organism's expressed version of a trait will be passed on to its offspring.

A certain mutation in the gene for hemoglobin results in the red blood cells becoming sticky,
rigid, and irregularly shaped. These irregularly shaped red blood cells block the flow of blood
throughout the body. A single base mutation is responsible for these irregularly shaped blood cells.
Which of these mutations most likely results in the mutated hemoglobin gene?
F. Insertion
G. Deletion
H. Duplication
J. Substitution
Answer:J
Explanation:Substitution
Mutation in genes can result in different types of abnormalities. In gene related to hemoglobin makes RBCs sticky, irregular shaped, this is because of substitution.
What is substitution?Mutation is a type of replication error during formation of new DNA.
In substitution mutation, incorrect nucleotide is placed at incorrect position during DNA replication, a point mutation occur in which a single nucleotide is substituted.
It actually does not add or remove any nucleotide from the sequence, just it substitute it.
In gene related to hemoglobin, the amino acid glutamic acid gets replaced with the valine amino acid at position 6 in beta-globin, which results in sticky, irregularly shaped red blood cells.
Thus the correct option is J.

Your lungs take in air through the mouth and nose. Explain how the lungs function in the human body.
A) They coordinate the movement of the heart.
B) They pass oxygen from the air into the blood.
C) They pump the blood throughout the body.
D) They remove carbon dioxide from the air.
Answer:
Your answer would be "B) They pass oxygen from the air into the blood."
Explanation:
They certainly don't coordinate the movement of the heart, so A isn't an option.
The lungs also don't pump blood through the body, that's the hearts job.
And the lungs do not filter carbon out of the air, which eliminates D.
Therefore your answer is B.
The lungs function in the human body by passing oxygen from the air into the blood.
Gaseous exchange in the lungGaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.
A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.
In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.
