Enzymes are made up of amino acids which are linked together via amide (peptide) bonds in a linear chain. This is the primary structure. The resulting amino acid chain is called a polypeptide or protein. The specific order of amino acid in the protein is encoded by the DNA sequence of the corresponding gene
Cushing syndrome is caused by an increase in the synthesis of cortisol in the adrenal gland. Which of the following compounds is directly required as a substrate for the synthesis of this hormone?
A) cholesterol
B) glucose
C) free fatty acids
D) amino acids
Answer:
Cholesterol
Explanation:
Cushing Syndrome occurs as a result of exposure of the body to elevated levels of cortisol hormone (stress hormone) for a long time. The elevated level of cortisol which is a steroid hormone, results from increased synthesis of cortisol in the adrenal glands. Cortisol is synthesized from a substrate called, cholesterol. Cortisol synthesis occurs in the zona fasciculata of the adrenal cortex and controlled or regulated by the hypothalamus-pituitary-adrenal axis or HPA axis.
Cholesterol, which is an important substrate in cortisol synthesis, is a lipid usually found in cells and plays an important function in hormone synthesis, food digestion and synthesis of Vitamin D.

Describe the concept of natural selection, using the Galapagos finches as an example. Imagine you were trying to explain the concept to someone who did not know what it is.
Answer and Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. It is a consequence of the individual differential capability to reproduce and leave offspring. There must be also a genetic base called heritability. Natural selection involves interactions between individuals, the physical environment, and the biological environment.
Natural selection results in adaptation, an increase of the aptitude phenotype. In many cases, adaptations, resulting from natural selection, can be correlated to environmental factors or selective pressures applied by other organisms.
The selective agent is the environmental characteristic that determines the differential survival of the phenotypic classes.
Some intraspecific phenotype variations follow a geographical distribution and can be correlated to changes in environmental conditions, such as temperature or humidity.
Adaptive evolution refers to changes in the organism that lead to the evolution of the species and that are adaptive to certain conditions of the environment. Birds adapt to diverse ecological niches showing specialized beak forms to improve functions such as feeding, mating, defending, competing, and etcetera. These factors play an important role in beak shaping. Natural selection produces adaptive evolution.
During 1977 Daphne Major island went through an important drought, and many plant species produced few or no seeds during and after the event. The medium ground finch population, which is seed-feeder species, was hardly affected by this phenomenon. As seeds´ production dropped and the sizes of the extisting seeds were considerably smaller, the finch population declined drastically from about 1400 individuals to a few hundred in a period of two years, approximately. The fact is that the island weather controls plant species development, and thus, seeds availability as food for the birds. Years later after the drought, the finches population managed to recover but showing differences in the size of their beaks. Before the drought finches had a stubby beak and many years after recovering the average size of the beaks was larger than the beak size of the original population. This difference in phenotype was due to the fact that during the drought, small seeds were very scarce, but large seeds with thick husks were still available. Small birds with small beaks starved because they were not able to open the husk and eat the interior of the seed. But those birds with bigger and stronger beaks were able to do so, and hence, managed to survive. The bird population adapted to the new environmental conditions and resource availability. Natural selection acted on the beak size, changing it.
There are different kinds of natural selection, but in the present example, directional selection is operating.
Directional selection increases the proportion of individuals with an extreme phenotypic trait, in this case, large beaks. This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
Furthermore, beak size is not only related to feeding strategies, but also to reproduction. Female finches only mate with males that have the same beak size.

Answer:
This question is incomplete, the question is asking to match each description with its gland.
1. Pituitary gland (hypophysis): The size and shape of a pea; produces hormones that stimulate other endocrine glands
2. Adrenal medulla: Is part of the sympathetic nervous system
3. Pancreas: Produces hormones that regulate glucose levels in the body
4. Parathyroid glands: Primary regulators of blood calcium levels
5. Thyroid gland: Produces the body's major metabolic hormones.
Explanation:
1. Pituitary gland is the gland known as the "master gland" because it produces hormones that coordinates the activities of other endocrine glands. The pituitary gland is shaped like a pea and functions to maintain the well-being of the body i.e. metabolism, growth etc.
2. Adrenal medulla is the inner part of the Adrenal gland, which is an endocrine gland located above the kidney. The adrenal medulla (a part of adrenal gland) is a part of the sympathetic nervous system which functions in control of blood pressure and heart rate.
3. Pancreas is a digestive organ that acts as a gland by secreting hormones that regulate glucose levels in the body. These hormones are insulin and glucagon
4. Parathyroid glands is an endocrine gland that produced the parathyroid hormone, which helps in the regulation of blood calcium ion levels.
5. Thyroid gland is an endocrine gland located in front of the neck. It produced series of hormones called thyroid hormones that functions in the body's metabolism

Which action is NOT a way to test a hypothesis? a. Analyze results b. Design an experiment c. Make a model d. Gather and evaluate evidence
Answer:
Make a model
Explanation:
A hypothesis is a plausible explanation of a given phenomenon of the natural world. This explanation (hypothesis) must be tested by using the scientific method.
The action 'analyze results' is NOT a way to test a hypothesis (Option a).A hypothesis can be tested (either confirmed or rejected) by experimental and/or observational procedures.The data collected by these experiments and/or observations can be then used as empirical evidence to support (or reject) the working hypothesis.In conclusion, the action 'analyze results' is NOT a way to test a hypothesis (Option a).

how does a plant get water form the ground
Answer:
Plants absorb nutrients and water through their roots, but photosynthesis — the process by which plants create their fuel — occurs in the leaves. Therefore, plants need to get fluids and nutrients from the ground up through their stems to their parts that are above ground level.
Explanation: How does a plant get water form the ground.
Answer:
It uses roots that suck up the water.
Explanation:
The roots are like tiny straws located in the bottom of a plant. They suck up water which goes up the stem. And the plants use that water to make food.

Answer is A:
Explanation:
Glycogen and starch are for ENERGY while cellulose and chitin are for STRUCTURE
Polysaccharides are complex carbohydrate molecules formed from monomeric molecules called monosaccharides. Polysaccharides perform varying functions in living organisms that possess them.The types of polysaccharides that we have are as follows:
Cellulose: Cellulose is the major component of plant's cell wall. It gives the cell additional structural strength. Chitin: Chitin is the major component found in the cell wall of fungi and exoskeletons of arthropods where it provides structural strength.Glycogen: Glycogen is the form of carbohydrate glucose is converted to when in excess in the bloodstream. It is stored in the liver and muscles. Glycogen is changed back to glucose when it is needed for energy production. Starch: Starch is the form by which plant cells store food. It is stored in the root and seed of plants. Starch is broken down into glucose when need arises for energy.Therefore, glycogen and starch are for ENERGY while cellulose and chitin are for STRUCTURE
