The part of the eye responsible for fine-tuning the refraction of incoming light is the _____. lens retina optic nerve cornea

Answers

Answer 1

Answer: The answer is the lens.

The eyeball is filled with a water-like fluid. In front of the eyeball, there is the cornea. It is a transparent structure that refracts light. A portion of light passes through the pupil which allows light to enter the eye. The amount of light that will pass through the pupil depends on dilatation of iris. Once the light enters the eye, it enters the lens. Lens of the eye is able to change its size and that way is responsible for fine-tuning the refraction of the light. The light later reaches the retina.

In humans tongue rolling is dominant to the inability to tongue roll. If a heterozygous tongue roller and a non-tongue roller have a child, what are the chances the child will be a non-tongue roller? A. 0 B. 0.25 C. 0.5 D. 0.75

Answers

Answer:

The chances of a child being non - tongue roller is $0.5\n$

Explanation:

Let the allele for dominant "tongue rolling trait" be represented by "T"

The allele for recessive "non-tongue rolling trait" be represented by "t"

The genotype of a heterozygous tongue rolling parent will be "Tt"

The genotype of a homozygous non- tongue rolling parent will be "tt"

If a cross is carried out between these two individuals , the offspring produced are as shown in the punnet square below-

T t

t Tt tt

So the number of offsrpings which are non- tongue roller are two in numbers represented by "tt"

So the chances that a child will be a non-tongue roller are

$(2)/(4) \n= 0.5\n$

Where , "4" represents the total number of offsprings produced

In humans, tongue rolling is dominant to the inability to tongue roll. The chances a child will be a non-tongue roller is C. 0.5.

White blood cells can leave the blood circulatory system.

TrueFalse

Answers

The statement "white blood cells can leave the blood circulatory system" is definitely true.

What is the circulatory system?

The circulatory system may be defined as a type of body system that significantly contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products.

White blood cells can also be known as the soldiers of the body. They can leave the bloodstream and migrates into tissues in the body. White blood cells play an important role in the immune system.

Here the different blood cells have different functions: Some fight intruders such as bacteria, viruses, parasites, or fungi themselves and render them harmless.

Various studies and reports suggested that the white blood cells -- actively open large gaps in the internal lining of the blood vessels, so they can exit through the vessel walls and rapidly get to areas of infection.

Therefore, the statement "white blood cells can leave the blood circulatory system" is definitely true.

Which of the following is part of the axial skeleton?arm

pectoral girdle

pelvic girdle

skull

Answers

The bone that is part of the axial skeleton is the skull. Theaxial skeleton refers to the part of the skeleton that consists of the bones ofthe head and the trunk of a vertebrate. In the human body, there are 80 bonesfound in the axial skeleton composed of six parts: the skull bones, theossicles of the middle ear, the hyoid bone, the rib cage, sternum, and thevertebral column.

Final answer:

The axial skeleton includes the skull, vertebral column, sternum, and rib cage. Out of the options, only the skull is a part of it.

Explanation:

The axial skeleton, one of the major parts of the human skeletal system, includes the skull, the vertebral column, the rib cage, and the sternum. Out of the options you've provided, the skull is a part of the axial skeleton. The arm is part of the appendicular skeleton, while the pectoral and pelvic girdle serve as connection points between the axial and appendicular skeletons and thus are not considered part of the axial skeleton.

The correct answer is A. B.

Answer:A

Explanation:

Farah is doing an experiment that involves calculating the speed of a longitudinal wave. What will most likely happen if she increases the temperature in the room?

Answers

The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.

Explanation:

In the given problem, Farah is doing an experiment that involves calculating the speed of a longitudinal wave

For example, Sound wave is a longitudinal wave. It travels faster in solid than liquid and gas as the solid is more denser.

The speed of the sound increases with the temperature. At higher temperature, the molecules have more kinetic energy. They can vibrate faster. The sound wave can travel faster. The speed of the sound in the room temperature is 346 m/s.

If Farah increases the temperature then the sound wave travels faster.

Cyanobacteria have been genetically modified to produce _______.a. oil
b. natural gas
c. isobutanol
d. none of the above

Answers

The correct answer is isobutanol.

Genetic engineering is the branch in which a little manipulation in the DNA of the organism can help in production of the desired product. The cyanobacteria belongs to the phylum of bacteria that performs photosynthesis.

The synthesis of isobutanol cab be done by genetically modified cyanobacteria as these modified cyanobacteria produce biofuels, such as isobutanol with the help of solar energy and carbon dioxide. They grow faster as compared to plants and absorb sunlight more efficiently so they can replenish more isobutanol.
