From where does soil come? What processes are used to form soil? Answer this in one paragraph.

Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

Which of the following statements best exemplifies the difference between a population and an individual?

Misha Larkins [42]

Answer:

d. All of the above exemplify the difference between a population and an individual.

Explanation:

A population is a group of individuals of the same species that live in a particular geographical area and are able to interbreed. A population is described with respect to several features such as death and birth rates, age structure, density, dispersion, change in the population size due to density-dependent and density-independent factors and the survivorship curve.

These features are not exhibited by a particular individual. Natural selection also works at populations. The evolutionary forces act upon populations to change their allele and genotype frequencies. Therefore, populations are the unit of evolution and change genetically over time, not the individuals. Population ecology studies the size of a populations and the trends and causes of changes in the populations over time.

During the cell cycle, A. DNA is replicated before mitosis begins. B. DNA is replicated once before mitosis and again before cyt

saw5 [17]

Answer:

The correct answer is A DNA is replicated before mitosis begins

Explanation:

DNA replication is one of the most significant event of a cell cycle. .DNA replication occur in the S phase or synthesis phase of the cell cycle.

DNA is replicated once per cycle to maintain to normal chromosome number in daughter cells.

DNA is replicated to form two new DNA molecules which are then equally distributed in each daughter cell during the mitosis phase.

In a certain breed of plants, dark green is determined by the dominant gene 'G' and light green is determined by the recessive g

oksian1 [2.3K]

Answer: If you crossed the parents of GG and gg all plants would be green because if the parent with two dominate genes could only give a dominant G to each child all children would have a dominate G gene therefore all children on this cross would be dark green.

Wave is a periodic (1) __________ that moves away from a source which carries (2) __________ with it. Waves can be typified acco

swat32

The correct answers to fill into the blank spaces are;

Wave is a periodic disturbance that moves away from a source which carries energy with it. Waves can be typified according to the direction of motion of the vibrating particles with respect to the direction in which the waves travel and according to medium .

Longitudinal waves vibrate perpendicularly to the direction in which the waves travel. This wave exhibits up and down motion. Longitudinal waves vibrate perpendicular or back and forth to the direction in which the waves travel.

Electromagnetic waves are combination of transverse and longitudinal waves. These move in a circular pattern as the waves pass by.

Mechanical waves need solid, liquid and gas medium to propagate or travel. Transverse, mechanical and surface waves are examples of mechanical waves.

Electromagnetic waves do not need medium to propagate. Radio waves, ultraviolet, infrared, and gamma rays are examples of electromagnetic waves. The nature of waves can be described through its terms, quantities and propagation.

The crust and trough refer to the highest point and lowest point of a wave pattern, respectively. The magnitude of a transverse wave is the maximum displacement of a particle of the medium on either side of its normal position when the wave passes. The frequency of periodic waves is the number of waves that pass a particular point for every one second while the Amplitude is the distance between adjacent crests or troughs.

The period is the time required for one complete wave to pass a particular point. The speed of the wave refers to the distance the wave travels per unit time. It is related to the frequency of the wave and wavelength through the following equation: wave speed= frequency x wavelength.

Silent or missense mutations are small-scale mutations that occur when

Andrei [34K]

Answer:

c. a single nucleotide is substituted with no effect

on the amino acid sequence.

Explanation:

silent mutations occur when the change of the dna

sequence within protein - coding portion of a gene

does not affect the sequence of amino acids that

make up the protein. this change typically takes

place at the third position of the codon also known

as the wobble position.
