Which are the functions of proteins?
A) Genetic information and regulation
B) Enzymes and antibodies
C) Hormones and steroids
D) Insulation and storage
Answer:
B)
Explanation:
because Enzymes & antibodies are the only one with proteins ')
Enzymes and antibodies are the functions of proteins. So the correct option is B.
What are protein structures?
The end products of the decoding process that begins with the Replication of cellular DNA are the proteins. Proteins are called the workhorses of the cell. They form all the motor and structural elements in the cell.
They also help in the catalysis of almost all biochemical reactions that take place in a living organism. These extreme ranges of functions are derived from a simple code structure that defines these diverse sets of structures.
In the cellular DNA, each of the genes codes for a unique structure of the protein. These proteins are assembled with unique sequences of amino acids.
These structures are held with each other by bonds and are folded in different varieties of three-dimensional structures. The linear amino acid sequence of the protein determines the folded shape or conformation.
Therefore the correct option is B.

Malthus' ideas regarding supply and demand influenced Darwin because limited natural resources force individuals to _______ with each other, and not every individual will have the opportunity to reproduce.
Answer:
compete
Explanation:
Limited natural resources force individuals to compete with each other and only strong individuals are able to compete and thereby reproduce effectively.
According to Malthus, population growth has the capacity to outrun the supply of food, and hence, if humans must experience better living conditions, there should a form of population control by controlling the birth rate.
Darwin extrapolated from Malthus' idea and opined that limited natural resources will only make individuals compete with each other and in this capacity, weak individuals might not be able to effectively compete, thus, leading to weakness in reproducing.

Which of the following best describes a scientific theory?
a. It cannot be changed.
b. It explains very few observations.
c. It may change.
d. It is basically speculation.
Answer:D. It is basically a speculation
The best description of a scientific theory is It may change.
Option C is correct.
How do we explain?A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Scientific theories are not facts, but they are based on facts.
Scientific theories can change if new evidence is found that contradicts the theory. For example, the theory of gravity was once thought to be absolute, but new evidence has shown that gravity is not constant, but varies depending on the mass of the objects involved.
Option C is correct.

What causes cystic fibrosis?
Answer:
Cystic fibrosis is caused by a change, or mutation, in a gene called CFTR (cystic fibrosis transmembrane conductance regulator). This gene controls the flow of salt and fluids in and out of your cells. If the CFTR gene doesn't work the way it should, a sticky mucus builds up in your body.

Explain how this experiment disproves the theory of spontaneous generation.
Answer:
The theory of spontaneous generation was suggests that the living organisms can come from inanimate objects, however it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.
He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.

he x-ray film shows a fracture where one side of the cortex is intact and flexed and the other side has signs of interruption (fracture). Which term best describes this type of fracture
Answer:
This is refers to as Greenstick fracture.
Explanation:
This is the type of fracture common in children less than 10 years, in which there is incomplete fracture of the bone,with ,but the cortex remain flexed.It is called green stick because it is analogous to the act of breaking a branch of a tree, which is not completely broken, from the main branch.
It is usually to due to falls,and common in kids because of their soft bones which is not completely formed and therefore will not break off completely like that of adults when fractured, but only from one side only.

Which is a property of water? A: it is a crystalline at room temperature, B: it expands as it melts, C: it dissolves non-polar substances, D: it has a large capacity to hold heat
Answer: D: it has a large capacity to hold heat
Explanation:
The property of water is that it has a large capacity to hold heat. It should be noted that in order to increase the temperature of water to a certain degree, it requires a lot of energy thereby water helps to regulate the temperature.
Other properties of water are that it is an excellent solvent, it is polar, it has adhesive and also cohesive properties.
The possibility that Mongolian ruler Genghis Khan spread an unusual chromosome to nearly 16 million men living today resulted from studies of ________.
A) proteomics
B) plasmids
C) the X chromosome
D) the Y chromosome
Answer:
D. the Y chromosome
Explanation:
Men have an X and a Y chromosome while women have two X chromosomes. Since the unusual chromosome was spread to nearly 16 million men, it was most likely a Y-linked trait as only men inherit a Y chromosome. If it was an X-linked trait, both men and women would be able to get it since both inherit X chromosomes.

Water is a polar molecule because it has an equal number of
Answer:
The correct answer is : proton and electron (opposite charges).
Explanation:
Water is a polar molecule as it has equal number of electron and proton. Electron and protons are present on different end of water molecule, negative charge due to electrons at end of oxygen, while positive charge at end of hydrogen due to protons.
Equal number of electron and proton make it neutral or no net charge molecule however having opposite charge on its end makes is polar.
Thus, the correct answer is: proton and electron.

What name is given to a large network of neurons within the brainstem that is essential for maintaining wakefulness
Answer:
These are the Reticular Activating system
Explanation:
These are network of neurons that occupy lager areas of the brainstem. They are located between the brain stem and the cortex.These neurons projected anteriorly into the hypothalamus, posteriorly into the thalamus to form the ascending RAS and emerged directly into the cortex.
Generally,the RAS is made up of 4 components.These are each made up of group of nuclei .The latter are simultaneously activated by the lateral hypothalamus,which cause the release of neurotransmitters that cause the modulatory effects produced by the entire RAS
Their major function is the control of sleepiness and wakefulness in individuals.It does this with the interactions with a lot of neurotransmitters present in the brain.
Besides the above functions the RAS is also responsible for the control of focus, stability of muscles tone.
