The answer is B. the number of cycles per second perceived by the human ear
I got this question right :)
The pitch is the number of cycles per second perceived by the human ear. The correct option is B.
What is pitch?The ability to assess sounds as "higher" and "lower" in the sense associated with musical melodies is known as pitch.
Pitch is a perceptual feature of sounds that allows their ordering on a frequency-related scale.
Pitch in physics refers to a sound wave's specific frequency, which is expressed in Hertz (Hz).
There are two ways in which these frequencies match musical notes. high tone: A high pitch is one that vibrates at a high frequency.
Pitch is a perceptual quantity that depends on the listener, but frequency is a physical quantity that indicates the number of vibrations per second. In truth, our ears perceive pitch rather than frequency.
The pitch is how many cycles per second the human ear can detect.
Thus, the correct option is B.

Morphological distinction is one of the steps necessary for speciation to occur.
What are the other two?
Answer:
Genetic Separation / Geographic isolation
Explanation:
Morphological distinction (or phenotypic differentiation) can be defined as the diversification of a set of observable physical characteristics in a population, capable of differentiating certain species.
The genetic separation occurs when the division of a group of genes into two or more pools of genes separated over time and depending on several other situational factors.
Geographic isolation occurs due to the physical separation of subpopulations of a given species. The barriers that isolate these subpopulations can be, for example, a river that cuts through a plain, a valley that divides plateaus or a portion of the sea that separates islands and continents.

Which parts of DNA provide the code for proteins?
Answer:
The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acid chains in proteins. DNA consists of the four nucleotide bases: adenine (A), guanine (G), cytosine (C) and thymine (T). RNA contains the nucleotides adenine, guanine, cytosine and uracil (U).
A gene is a section of a DNA molecule that contains the information to code for one specific protein.
The DNA code contains instructions needed to make the proteins and molecules essential for growth, development and health.What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Many genes do not code for proteins.What is DNA?

A dominant allele is often covered up or masked by the recessive allele. True or false?
Answer:
Explanation:In a heterozygote, the allele which masks the other is referred to as dominant, while the allele that is masked is referred to as recessive.
Answer:
If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked. In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present

Which of the following BEST explains how scientists are able to determine the
structure of Earth's interior?
1) Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface.
2)Drilling deep within the Earth.
3)By cutting into other terrestrial planets.
4) Our modern knowledge of the Earth's interior is just a guess that many scientists have accepted.
Answer:
I think number 1 is the answer.
Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface. The correct option is 1.
What are seismic waves?Seismic waves are caused by sudden movement of materials within the Earth, such as fault slip during an earthquake.
Seismic waves generated by earthquakes or explosions can travel through the Earth's interior, revealing information about the properties of the rocks and other materials they pass through.
In addition to seismic data, scientists use other indirect methods such as magnetic and gravitational field studies, as well as analyses of rocks and minerals found at or near the surface.
Scientists collect indirect evidence by observing seismic waves (Earthquakes) as well as what is visible on the Earth's surface.
Thus, the correct option is 1.

a. The reactants of photosynthesis are the reactants of cellular respiration.
b. Photosynthesis produces light energy while cellular respiration produces chemical energy.
c. The products of photosynthesis are the reactants of cellular respiration.
d. Photosynthesis and cellular respiration use light energy to convert to chemical energy.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?

what is the full form of tree
Explanation:
A tree or large tree is called a long-standing woody plant. In botany, the tree is one of the most durable plants that maintains its leaves by growing a stem or trunk. In some definitions, the use of the tree is such that it is the only woody plant. It is the only plant from which wood is obtained. It is not possible to determine the exact height of the trees, but overall the adult trees reach at least 6 meters [citation needed]. In the structure of the tree there are usually branches that are attached to a large trunk. Compared to other plant and animal species, trees have a long life. Some species of trees are more than 100 meters tall, and some live for thousands of years. Trees are important elements of natural landscape, gardening and landscaping. [1]

The sperm and the ovum are called haploid (as they have only 23 chromosomes) which is half the number of chromosomes seen in all the other human body cells. What is the significance behind the maintenance of this special chromosomal number in the male and female gametes?
Answer:
During the process of meiosis(The process of cell division through which the germ cells such as the reproductive cells are formed), the sex cells produced are haploids (have only 23 chromosomes). This is significant as during the process of fertilization, the nucleus of the sperm (containing 23 chromosomes) and the nucleus of an egg (containing 23 chromosomes too) fuse, hence, retaining the original number of chromosomes in the zygote formed. i.e 46 chromosomes.

explain how and why an earthquake occurs in thorough detail. You should also be identifying the four labels below within your explanation. A good answer would be longer than a paragraph (but < 3)
Answer:
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!
