Answer:
Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously.
Explanation:
This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

All of the following statements about what happens during the fasting / post-absorptive state are correct EXCEPT:
A.) Muscle is breaking protein into amino acids.
B.) Fat cells are breaking tryglicerides into fatty acids. C.) Many tissues rely on ketones for energy
D.) Amino acids are broken down to ketones
E.) All of these statements about the post-absorptive state are correct
Answers
The correct answer is E.) All of these statements about the post-absorptive state are correct. The state of the body between meals or while fasting is referred to as the post-absorptive state.
Amino acids are broken down to ketones, which can be used by the body's cells as an alternative source of fuel during the fasting/post-absorptive state. In addition to ketones, the brain may also use glucose generated by the liver from glycogen or other non-carbohydrate sources. However, some tissues, such as skeletal muscle, may break down protein into amino acids and use them for fuel. Fat cells break down triglycerides into fatty acids, which are also used as fuel by various tissues. During the fasting/post-absorptive state, the body makes use of its energy reserves to keep critical organs, such as the brain, functioning correctly. Many tissues, such as the brain, red blood cells, and the renal medulla, rely on ketones for energy. The body also takes steps to preserve its energy reserves during this time, such as reducing its basal metabolic rate. However, the body's energy stores can only last for a limited period, and eventually, it will need to refuel.

which of the following must occur for one species to split into two or more species? select one: a. the species must move into a new habitat. b. dna sequences of genes must accumulate differences. c. morphological changes must be obvious within the population. d. one species must undergo geographic isolation.
Answers
DNA sequences of genes must accumulate differences for one species to split into two or more species.
This process is known as speciation.
An explanation for this is that as DNA sequences accumulate differences over time, individuals within a population may become genetically distinct from one another.
This can lead to reproductive isolation, where individuals from different populations are no longer able to interbreed and produce viable offspring.
Eventually, these genetically distinct populations may evolve into separate species.
A summary of the answer is that genetic differences are essential for speciation to occur.

The two concepts "growth" and "development" that have probably given us the most trouble over our academic careers are these.
Growth is the simple definition of "an increase in size and mass of a specific organism over time," whereas "development" covers a wider range of topics.

You recently identified a novel protein that contains several membrane-spanning domains. You would predict that the amino acids embedded in the membrane would have groups. A. nonpolar B. negatively charged C. polar uncharged D. positively charged
Answers
When a protein contains several membrane-spanning domains, the amino acids embedded in the membrane are predicted to have nonpolar groups.
Membrane-spanning domains are regions of proteins that traverse the lipid bilayer of a cell membrane. These domains are typically composed of amino acids with specific characteristics to interact with the hydrophobic environment of the lipid bilayer.
The lipid bilayer is a hydrophobic region, meaning it repels water. To effectively span the membrane, the amino acids embedded in these regions of the protein need to have nonpolar characteristics. Nonpolar amino acids are hydrophobic, meaning they do not readily interact with water molecules.
Nonpolar amino acids, such as alanine, valine, leucine, and isoleucine, have hydrophobic side chains that lack charged or polar groups. These side chains are compatible with the hydrophobic core of the lipid bilayer and help anchor the protein within the membrane.
In contrast, amino acids with polar or charged side chains (such as negatively charged, positively charged, or polar uncharged) tend to be located on the surface of the protein, where they can interact with water molecules or other polar/charged molecules outside the membrane.
Therefore, based on the presence of multiple membrane-spanning domains, it is predicted that the amino acids embedded in the membrane would have nonpolar groups.

For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).
Explanation:
Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.
The RNA pairing rules is that each nitrogenous base has a complementary base, so:

Compare and contrast evaporation and convention and how the processes move water through the water cycle
Answers
Answer:
Evaporation and convection are both heat transfer processes that transfers heat from hotter to colder regions. Evaporation however involves a change of state of the molecules whereas convection does not, rather occurs due to difference in densities of the molecules.
In the water cycle, both evaporation and convection work to lift liquid water from the earth's surface into the atmosphere where they condense into water vapor and eventually fall as rain.
Explanation:
Evaporation is a process by which a liquid turns into vapor when it absorbs heat.
Convection is the process of heat transfer by the actual movement of the heated molecules from one region to another.
Comparison:
Both processes involves transfer of heat
Both processes involves movement of molecules
Contrast:
Evaporation involves a change of state of the molecules, whereas convection does not.
Evaporation is a surface phenomenon whereas convection occurs throughout the whole fluid in cycles
Evaporation results takes heat away from a body whereas convection transfers heat to a body
In the water cycle, when the heat from the sun heats up the earth's and water surfaces, the water molecules absorb heat and turn to water vapor by the process of evaporation. The water vapor rises into the atmosphere.
During convection in the water cycle, heated air near the earth's surface rises as it becomes less dense than cold air and carries along water vapor with it into the atmosphere. As the hot air water vapor mixture rises, it becomes cold and condenses into water vapor which later falls as rain.

find the rate of change of the volume of a balloon (sphere) with a circumference increasing by at 3picm per minute when the radius is 5cm
Answers
The rate of change of the volume of the balloon (sphere) is 150π cubic cm/min. The formula for the volume of a sphere is given by; V = (4/3)πr³.
Given that the circumference of a balloon (sphere) is increasing at a rate of 3π cm/min and the radius is 5 cm, we have to find the rate of change of the volume of the balloon. We know that the formula for the volume of a sphere is given by; V = (4/3)πr³. Differentiating with respect to time gives; dV/dt = 4πr² × dr/dt
We know that the circumference of a sphere is given by; C = 2πr
Differentiating with respect to time gives; dC/dt = 2π × dr/dt
Now we can find the value of dr/dt from the above expression; dr/dt = dC/dt ÷ 2πPutting the given value in the above expression, we have ;dr/dt = 3π ÷ 2πdr/dt = 3/2 cm/min
Now substituting the value of r and dr/dt in the expression for dV/dt; dV/dt = 4πr² × dr/dt dV/dt = 4π(5)² × (3/2) dV/dt = 150π
Therefore, the rate of change of the volume of the balloon (sphere) is 150π cubic cm/min.

Tree-dwelling primates have prehensile tails for gripping branches. Considering recent ancestors, the prehensile tail trait can be considered as a convergence example that occurred among different groups.

The composition of the DNA can be calculated using the Chargaff's rule. According to the rule, the number of cytosine will be equal to guanine and the number of thymine will be equal to adenine and vice versa. So, C = 15%, G = 15%, T = 35%, A = 35%.
While thymine is often only found in DNA and uracil is only found in RNA, guanine, along with adenine and cytosine, is present in both DNA and RNA. The two tautomeric forms of guanine are the common enol form and the main keto form (see figures).
