Explain the role of the ozone layer in sustaining life on Earth.
Answer:
The O3 layer, (Ozone Layer) leads a greatly significant role in sustaining life on Earth. It acts as a barrier against the harmful UV rays from the Sun. The Ozone and Oxygen molecules are able to absorb a staggering 95% to 99.9% of the ultraviolet radiation travelling to our planet. When this ultraviolet radiation is absorbed, heat is generated.
Answer:
The ozone layer helps regulate the Earth’s temperature by absorbing a large percentage of the UV radiation entering the atmosphere. This protects living organisms from exposure to large amounts of UV radiation, maintains livable climates, and regulates the amount of harmful ground-level ozone.

Southern Florida has many tropical hardwood hammocks—forest habitats that are warm, wet, and populated with many broad-leaved evergreen trees. Why might a plant native to an ecosystem with a cooler climate do well if introduced to a tropical hardwood hammock? Group of answer choices The trees in the tropical hardwood hammock are better at competing for native resources than the introduced species are. The wet conditions in the tropical hardwood hammock disrupt the life cycle and limit reproduction of the introduced species. Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock. Pollinators and seed carriers that normally increase the population in the cooler climate are lacking in the tropical hardwood hammock.
Answer:
Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock.
Explanation:
The tropical hardwood hammocks are habitats that act as small ecosystems markedly different from the surrounding environment, and they may be seriously threatened by introduced plant species. In Florida, exotic plants have been introduced into the tropical hardwood hammock habitat, reaching to about 50% of the flora in some areas. The mature hammock of these habitats can generate a shade that maintains a temperature of several degrees cooler compared to their neighboring habitats, and thereby promoting invasion by exotic species.

The thermoreceptors of the sensory afferent pathway were activated when they perceived high temperatures, and after that they sent a signal to the CNS for it to execute the "withdrawal" reflex in the face of danger or pain.
The reflex act is an immediate and unconscious action, like walking, and like other movements that are coordinated between the CNS, SNP, NEUROMUSCULAR PLATE AND MUSCLE.

THE ANSWER IS D YOU ARE WELCOME
During a science lab the teacher provided Michael with a triple-beam balance, a ruler, and four cube-shaped metals. Based on Michael's calculations and the table below, the conclusion can be BEST made Substances can be identified by their density
what is density?
Density refers to the mass of a unit volume of a material substance. The formula for density is represented by d = M/V, where d is density, M is mass, and V is volume.
It is commonly shown as units of grams per cubic centimeter, it can also be expressed as kilograms per cubic meter .
Density can used to define how different materials interact when mixed together. For example Wood floats in water because it has a lower density, while an anchor sinks because the metal has a higher density.
Density can be applied in pipe design, shipbuilding, helium balloons, weight distribution in the aero plane, and the fact that ice floats on water.

Please write a 1 page explanation of Mitosis, how it occurs, where it occurs, why it occurs, we will discuss it tomorrow. Make sure you cover all of the phases and describe what occurs in each.
Answer: Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
The great majority of the cell divisions that happen in your body involve mitosis. During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones. For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population.
In all of these cases, the “goal” of mitosis is to make sure that each daughter cell gets a perfect, full set of chromosomes. Cells with too few or too many chromosomes usually don’t function well: they may not survive, or they may even cause cancer. So, when cells undergo mitosis, they don’t just divide their DNA at random and toss it into piles for the two daughter cells. Instead, they split up their duplicated chromosomes in a carefully organized series of steps.

no

Deforestation is the permanent destruction of forests in order to make the land available for other uses. This process leads to fewer plants being available to conduct photosynthesis. Which of these is a possible effect of deforestation on the process of cellular respiration?
Answer:
A lesser amount of oxygen will be available for cellular respiration
Explanation:
Deforestation can be defined as the permanent removal of trees in forest areas for other land uses (for example, agriculture use). It is well known that deforestation has a negative effect on natural ecosystems. An important proportion of the oxygen in the air is generated by plants during photosynthesis, and it has been estimated that about 30% of the land photosynthesis is due to tropical forests. Aerobic cellular respiration is a metabolic pathway by which organisms use oxygen to produce energy in the form of ATP. In consequence, deforestation represents a serious problem to sustain cellular respiration, and ultimately to sustain life.
Answer:
Less oxygen is available for use during cellular respiration.

Why is the following molecule nonpolar and hydrophobic?
The image shows a polymer composed of a chain of 14 carbon atoms. The first carbon atom is bound to three hydrogen atoms. The next 12 carbon atoms are bound to two hydrogen atoms. The final carbon atom is bound to a carboxyl group.
The carbon and hydrogen atoms share electrons equally.
The glycerol molecule in fats contains a carboxyl group.
There are exactly three fatty acid chains present in each fat molecule.
There is an unequal distribution of hydrogen and oxygen atoms.
Answer:
a
Explanation:
The following molecule is nonpolar and hydrophobic because the carbon and hydrogen atoms share electrons equally. The correct option is A.
What are nonpolar and hydrophobic?Non-polar molecules are those which can not be dissolved in water. These molecules have ends that are not dissolved in water. Hydrophobic is a quality of the substance that is not dissolved in water or repels water.
The image shows a polymer made up of three hydrogen atoms are bonded to the initial carbon atom. Two hydrogen atoms are joined to the next 12 carbon atoms. A carboxyl group is attached to the last carbon atom.
Since charges fluctuate, a momentary dipole moment exists in a so-called nonpolar molecule.
Thus, the correct option is A, The carbon and hydrogen atoms share electrons equally.

Glucose is small (6 carbons) and dissolves easily in water because it has a number of polar OH groups attached to its carbons. Now lipids, they are constructed of long chains of carbon and hydrogen called fatty acids. These chains are not polar and lipids do not dissolve or mix well with water for this reason.
