Let p represent the dominant allele for a trait and q represent the recessive allele for that trait. If the frequency of q is 0.2, then what would be the frequency of the heterozygotes in the population
The frequency of the heterozygotes in the given population is 2pq which is O.32, where p represents the dominant allele for a trait and q represents the recessive allele for that trait.
What do you mean by Heterozygotes?The heterozygotes may be defined as the presence of two different alleles at a particular gene locus.
In the given population, the frequency of the q allele = 0.2.
Then, according to Hardy-Weinberg genetic equilibrium, the frequency of the p allele = 1 - 0.2 = 0.8.
∴ The frequency of heterozygotes, 2pq = 2×0.8×0.2 = 0.32.
Therefore, the frequency of the heterozygotes in the given population is 2pq which is O.32.

25. A nerve fiber that conducts impulses toward muscles and glands is called a __________ fiber. A nerve that conducts impulses toward the brain and spinal cord is called a __________ fiber.
Answer:
A nerve fiber that conducts impulses toward muscles and glands is called a _____motor_____ fiber. A nerve that conducts impulses toward the brain and spinal cord is called a ______afferent____ fiber.
A nerve fiber that conducts impulses toward muscles and glands is called a motor neuron fiber. A nerve that conducts impulses toward the brain and spinal cord is called a sensory nerve fiber. Both are important for the proper functioning of the body.
What are sensory and motor nerve fibers?The sensory nerve fibers send the stimulus in the form of an impulse from the sensory organs to the spinal cord, where the sensory organs can be skin, eyes, etc. An example is when a person sees a dog coming towards them, and the sensory nerve fiber that is associated with the eye sends the signal from the eye to the spinal cord. The spinal cord takes proper action by sending the motor nerve fibers to the effector organ, which is the leg muscle. In this case, the individual will run.
Hence, A nerve fiber that conducts impulses toward muscles and glands is called a motor neuron fiber. A nerve that conducts impulses toward the brain and spinal cord is called a sensory nerve fiber.

How does exhaling remove waste from the body? Explain the systems that make this happen, using complete sentences.
Answer:
THERE IS A SYSTEM OF BODY CALLED THE EXECTORY SYSTEM
Explanation:
The organs of this system get rid of a certain waste. The skin gets rid of sweat. The lungs get rid of carbon dioxide and water vapor. The liver gets rid of bile, which, in addition to breaking down fats, is partially made up of the breakdown of red blood cells. The kidneys get rid of toxins from the blood. The large intestine gets rid of undigested food. in this way the Dermal, Respiratory, Lymphatic, Urinary, and Digestive Systems work together to get rid of wastes.

Why tomatoes are red in colour??
Answer:
The color of a tomato begins to change as it ripens, from green to yellow, and ultimately to red. This is due to the breakdown of chlorophyll, which results in the formation of lycopene, a red carotenoid (a pigment group). When the tomato is fully ripe, the carotenoid becomes the predominate color, which is red.

In 2001, scientists found a fossilized skeleton from about 110 million years ago. The fossil resembled a modern crocodile in virtually every way, except for one: The fossil was 40 feet long, which is almost twice as long as the largest modern crocodile ever found. From this discovery, scientists concluded that
We can confirm that scientists used this discovery to conclude that crocodiles evolved to be smaller over time.
Why would small size help Crocodiles?Over time, many animals on the Earth evolved to smaller sizes. This made large predators unlikely to survive as they would need to hunt much more often than that of smaller predators in order to sustain themselves. This along with an increase in mobility explains some of the reasons why it was beneficial for crocodiles to evolve to be smaller over time.
Therefore, we can confirm that scientists used this discovery to conclude that crocodiles evolved to be smaller over time.

Water is wet because its viscosity is low.
What is viscosity?Viscosity is a metric for a fluid's flow resistance. It speaks of the internal friction of a fluid in motion.
A fluid with high viscosity resists motion due of high internal friction caused by its molecular structure. Low viscosity fluids flow freely because their molecular structure causes little to no friction when they are in motion.
The thickness of a fluid is another name for viscosity. You can picture honey and low-viscosity water (high viscosity). However, when considering fluids with varying densities, this concept can be unclear. The interaction of the various molecules in a fluid results in viscosity at the molecular level.
Therefore, Water is wet because its viscosity is low.

The maximum plasma concentration of a substance that can be carried in the blood without eventually appearing in the urine is called the
Answer: renal threshold
Explanation:
The maximum plasma concentration of a substance that can be carried in the blood without eventually appearing in the urine is called the renal threshold.
The renal threshold refers to the maximum concentration of a substance in the blood plasma that can be filtered by the kidneys without being reabsorbed and eventually appearing in the urine. It is a critical concept in renal physiology and is specific to each substance.
When the plasma concentration of a substance exceeds its renal threshold, it surpasses the kidney's capacity to reabsorb it, resulting in the substance being excreted in the urine. Below the renal threshold, the substance is effectively reabsorbed by the renal tubules and remains in the blood.
The renal threshold varies depending on the substance and can be influenced by factors such as renal function, hormonal regulation, and overall health. Monitoring the renal threshold of certain substances can be clinically relevant in assessing kidney function and diagnosing certain conditions, such as renal tubular disorders or diabetes.
