How does your nose filter the incoming air?
Answer:
Air enters through the nostrils of the nose and is partially filtered by the nose hairs, then flows into the nasal cavity. The nasal cavity is lined with epithelial tissue, containing blood vessels, which help warm the air; and secrete mucous, which further filters the air

please help!!!
Answer:
B.
Explanation:
When you touch something the sensory nerves carry it to the brain while your motor nerves tell you to touch it. So being carried to and from. I also got it right on the quiz.
Sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS. Therefore, the correct statement is option B.
What is central nervous system?The central nervous system (CNS) includes the brain and the spinal cord responsible for processing information received from peripheral nervous system (PNS) to generate appropriate responses. The brain is the most complex organ of the CNS, carries various functions, including sensation, perception, movement, etc.
Sensory nerves transmit information from sensory receptors, such as those in the skin, muscles, etc. to central nervous system (CNS) and sensory nerves are activated by various types of stimuli.
Motor nerves transmit signals from the CNS to muscles, and other effectors throughout the body. These signals are responsible for activation of muscle contractions, produce movements, and other responses.
Therefore, sensory and motor nerves both work together to perform physiological functions where sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS.

What did you include in your response? Check all that apply Longitudinal and transverse waves are mechanical waves, so they both carry energy through particles of matter. Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.
Answer:
Longitudinal waves are waves that transfer energy parallel to the direction of wave motion.
Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.
Explanation:
First of all, transverse waves are not mechanical waves at all. Longitudinal waves are mechanical waves.
Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. A typical example of longitudinal waves is wave on a spiral spring.
Transverse waves are waves that transfer energy perpendicular to the direction of wave motion. A typical example of a transverse wave is light wave and other electromagnetic waves.
Why are silent mutations possible for some of the amino acids?
Answer:
That's possible because proteins are encoded by "triplets" of nucleotides, each responsible for adding a particular amino acid to the protein chain. A change in one nucleotide, however, doesn't always change the triplet's meaning; the mutated triplet may still add the same amino acid.

what system carries auxin to move to the darker side?
Vascular system.
Phototropisms are caused by an unequal distribution of auxin. This makes the plant grow either towards or away from the light, depending on which part of the plant receives the light.
In a stem, the cells on the shaded side contain more auxin and grow longer than the cells on the light side. This causes the stem to grow towards the light. It is vital to note that the plant does NOT bend towards the light.
Phototropisms are a result of an unequal distribution of auxin. This makes the plant develop both in the direction of or far from the mild, relying on which part of the plant gets the mild.
In a stem, the cells at the shaded aspect comprise greater auxin and develop longer than the cells at the mild aspect. This reasons the stem to develop in the direction of the mild. It is crucial to be aware that the plant does NOT bend in the direction of the mild.
What are auxins?Auxins are a category of plant hormones (or plant-boom regulators) with a few morphogen-like characteristics. Auxins play a cardinal position in the coordination of many boom and behavioral procedures in plants cycles and are important for plant frame development.
Thus it is clear that the system that carries auxin to move to the darker side is the vascular system.

Do the plants and animals on a farm make up an ecosystem? Why or why not?
Answer:
Yes they do
Explanation:
Animals and plants make up a ecosystem because the animals feed off the plants and the animals feed off of other animals.

If data for the growth of this bacterial population continued to be recorded, would the data point at 60 hours be above or below 37 million? Support your answer.
Answer:
Above 37 million
Explanation:
Explanation in picture below
Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.
Thus, Bacterial population growth occurs geometrically or exponentially: in each division cycle (generation), one cell produces 2 cells, then 4 cells, then 8 cells, then 16, then 32, etc.
The relationship shows that the average generation time is constant and the growth rate of the bacterial population is proportional to the number of bacteria at any given time.
This relationship is valid only during the period when the population grows exponentially, ie. in the logarithmic phase of growth. Therefore, graphs showing the growth of bacterial cultures are plotted as the logarithm of the number of cells.
Thus, Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

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.

Why does the grass look green under sunlight and black under the moonlight?
Answer: The original colour of grass is green because of photosynthesis. But in terms of reflection, it looks green because the sunlight reflects the green colour off the grass, so we see it as green.
Explanation: Sun appears white, but it is made up of the colors: red, orange, yellow, green, blue, indigo, and violet. When white light hits an object, it absorbs some colors and reflect the others. Grass appears green because it absorbs all the wavelengths except green. Green is reflected off the grass, so we see grass as green. The moon doesn’t have light of its own, the moon lights up because of the sun. So at night, as the light of the sun doesn't reach the grass directly because of the moon, it doesnt reflect any color off the grass, and so our eyes detect grass as black.

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.
Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.
An eye can be defined as a specialized organ of sight with the capability to receive visual images that are subsequently transduced into neural signals and relayed to the brain for processing and interpretation. Some of the components of the human eye matched with their description are;
1. Aqueous humor: a transparent liquid which is located between the cornea and iris.
2. Ciliary muscles: muscles attached to the lens to change its shape.
