A basic fatty acid has a long chain of carbon atoms (generally even in number) along with a carboxyl group at one terminal. The fatty acid may be saturated or unsaturated depending upon the presence of double bonds.
Fatty acids are the carboxylic acids due to the presence of the carboxyl group. In an organism's body, fatty acids are the source of energy. Besides they are also involved in the formation of phospholipids which are an essential component of cell membrane.
Unsaturated fatty acids are those that contain one or more double bonds. This gives a little kink to their structure which is very essential for the fluidity of cell membranes. They are less stable than the saturated fatty acids and are also more prone to rancidity.

a kind of foliated metamorphic rock
The word form the list that best fits the definition of "a kind of foliated metamorphic rock" is "NonFoliated" (Option D.
What is a non-foliated metamorphic rock?Nonfoliated metamorphic rocks form near igneous incursions when temperatures are high but pressures are modest and equal in all directions. Non-foliated metamorphic rocks have no layered or banded surface, such as hornfels, quartz, quartzite, and novaculite.
Because not all parent rocks feature platy or elongated minerals, the individual mineral grains do not align during metamorphism. Marble, quartzite, and hornfels are examples of non-foliated metamorphic rocks.
Foliated rocks feature minerals that are platy or elongate and are oriented in generally parallel planes or wavy bands or planes. Nonfoliated rocks may have colorful bands that reflect minute impurities in the rock, but there is no obvious alignment of the dominating minerals.

A. they will not develop sickle-cell disease
B. they will show some symptoms of the disease because the allele that causes sickle-cell disease is not really recessive
C. they will be more apt to acquire a serious case of malaria
D. they will have full-blown sickle-cell disease because the allele is dominant
E. none of the listed choices are correct
If an individual is heterozygous for the sickle cell trait, they will show not develop sickle cell disease. Option A.
Sickle Cell DiseaseSickle cell anemia is a disease of the blood that is homozygous and recessive. Consequently, an individual needs to have two copies of the recessive allele in order to be affected by the disease.
Now, if an individual is heterozygous for the sickle cell allele, it means such an individual has only one recessive allele which is not enough for the disease to be expressed.
This is why individuals that are heterozygous for the sickle cell trait don't show symptoms of the sickle cell disease. Instead, they enjoy a hybrid vigor that confers malaria resistance. Hence, they do not have malaria as often as those that are homozygous dominant.
Homozygous recessive traits are different from dominant traits. In the latter, only a copy of the allele is needed to be dominant, at least, in order for the trait to be expressed.

describe the basic functions of animal body system
The basic functions of the animal body system are regulation of the internal environment (homeostasis), nutrient absorption, reproduction, and defense against injury or illness.
Homeostasis:
A biological system's tendency to preserve stability while responding to conditions that are best for survival is known as homeostasis. If homeostasis is achieved, life continues; if it is not, tragedy or death results.
Nutrient absorption:
The upper small intestine's hollow serves as a reservoir for absorbed food molecules, water, and dietary minerals. The majority of the absorbed substances penetrate the mucosa into the blood and are transported there by the bloodstream to other body areas for storage or additional chemical alterations.
Reproduction:
The process of producing off-springs that are biologically or genetically similar to the parent organisms is known as reproduction. Reproduction allows and ensures the continuity of species, it's the main feature of life on earth.

Pressure is force (in newtons, N) divided by the area ( in square meters, m2 ) over which it acts (P = F/A). Volume is the amount of space is taken up by an object or, in our case, a parcel of gas.
The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro's law).
Hence, for a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.

The following lists components of the nature of science. Explain how at least two of these are related to the cell theory:
Scientific knowledge is durable yet subject to change
Science is a social activity
Knowledge is created through the process of science. Both thorough observation of occurrences and the creation of theories to explain those observations are essential to the process. Knowledge will always change since new observations could refute accepted ideas. No matter how well one theory explains a given collection of observations, it is always feasible that another theory will fit the same set of observations just as well, better, or across a larger range.
The majority of scientific knowledge is enduring, despite the fact that scientists reject the idea of discovering perfect truth and accept some doubt as a component of nature. Science typically modifies ideas rather than rejects them completely because strong theories are more likely to endure, advance in accuracy, and gain widespread acceptance. For instance, when developing the theory of relativity, Albert Einstein did not completely reject the Newtonian laws of motion but rather demonstrated that they were only a rough approximation with a more general concept.
This seems like a strange restriction because it is obvious that both modern science and the majority of earlier science is a social activity. For information, samples, techniques, and many other things, scientists depend on one another. Their interactions are occasionally competitive and frequently cooperative.
