Answer:
Because of side chain interactions, the sequence and location of amino acids in a particular protein guides where the bends and folds occur in that protein (Figure 1). The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.

- The genome of P. larselli is over 2x the size of p-richmondi, but they have approximately the same number of genes. What accounts for the difference in genome size
Plethadon is a genus inclusive of the salamander family.
As a genus,it has a high rate of inter species genetic variability, The C value which is a measure of genetic variation in species is very high especially in this genus.
Low rate of mutation, climatic niche and low rate of DNA loss etc are some of the various factors.
p.larselli and p.richamondi has a difference in genome size and this difference can be attributed to the presence of more DNA segments
that are none coding in larselli compares to that of richamondi.
The DNA fragments that does not code for protein are the non coding sequence but they have some other revolutionary and evolutionary functions.
Some of these sites that doesn't code can be small repeating sequence, microsatellites and variable number tandem repeats etc and these shows high chances that richamondi have lost some of these sequence that are non coding from it's chromosome as part of a genetic or epigenetic changes during the course of evolution or there might be also a high rate of mutations among them leading them to loose some DNA fragments.

How does surface tension work with water molecules?
Answer:
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. At the surface, though, the outmost layer of molecules, has fewer molecules to cling to, therefore compensates by establishing stronger bonds with its neighbors, this leading to the formation of the surface tension.
Surface Tension of Water . The surface tension of water is 72 dynes/cm at 25°C . It would take a force of 72 dynes to break a surface film of water 1 cm long. The surface tension of water decreases significantly with temperature as shown in the graph. The surface tension arises from the polar nature of the water molecule.

B. Chemical energy in the form of glucose is needed for both cellular respiration and photosynthesis.
C. Chemical energy in the form of glucose is needed for photosynthesis, and solar energy is needed for cellular respiration.
D. Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.
Answer:
solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration
Explanation:
The statement that accurately describes the energy needs for photosynthesis and cellular respiration is: Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.
PHOTOSYNTHESIS AND CELLULAR RESPIRATION:
Photosynthesis is the process by which green plants obtain their food (glucose) using energy from sunlight. Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells. Photosynthesis makes use of energy from the sun i.e. solar energy as its power source while cellular respiration releases the energy stored in glucose to power the process. Therefore, the statement that accurately describes the energy needs for photosynthesis and cellular respiration is: Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.Learn more about photosynthesis and cellular respiration at: https://brainly.com/question/18728019?referrer=searchResults

Carnivorous plants and legumes (e.g., peas, soybeans) both absorb key nutrients directly from other organisms. How is nutrient acquisition in pitcher plants similar to that in legumes
Answer:
They acquire nitrogen from the insects they eat.
Explanation:
Pitcher plants is a canivorous plants.
Since both legumes and pitcher plants absorb nitrogen from other organisms, pitcher plants have specialised pitfall trap called pitcher found at their leaves which help help to trap, and digest insects that are prey. The obtained about 80% nitrogen from the insects they eat which is captured by their leaves.. They release digestive enzymes which acts on their insects and then decompose by bacteria to release nitrogen . This nitrogen is turn to liquid which is absorb as liquid and use for growth.
When should we clessify something as not living?
Answer:
A non-living thing is anything that was never alive. In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.

Answer:
Explanation:
The fossil was formed when the animal died. Then sand got blown on to the top of it. Then it got more sand blown on top. Then it rained and that turned into mud. And over time the mud got harder and dried and turned back into sand and some of that sand blew off of the fossil then the fossil rose up more out of the ground.

Which best describes the flow of oxygenated blood through the heart?
Question 1 options:
Left pulmonary veins, right atrium, right AV valve, right ventricle, aortic semilunar valve, aorta
Pulmonary veins, left atrium, left AV valve, left ventricle, aortic semilunar valve, aorta
Superior vena cava, left atrium, left AV valve, left ventricle, pulmonary semilunar valve, left pulmonary artery
Superior vena cava, right atrium, right AV valve, right ventricle, pulmonary semilunar valve, left pulmonary artery
Answer:
Explanation:
Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
The correct option that describes the flow of oxygenated blood through the heart is B, Pulmonary veins, left atrium, left AV valve, left ventricle, aortic semilunar valve, and aorta.
The left atrium is where oxygenated blood enters the heart after traveling from the lungs to the heart via the pulmonary veins. The left AV (atrioventricular) valve, also referred to as the mitral valve, allows blood to pass from the left atrium into the left ventricle.
The aortic semilunar valve, the body's primary artery that carries oxygenated blood to all the organs and tissues, is opened as the left ventricle contracts, pumping blood out into the body.

Explain the difference between macrostates (external arrangements of particles) and microstates (internal arrangements of particles).
Macrostates and microstates may be defined on the basis of their properties and characteristics. Both are part of any system.
What do you mean by Macrostates?Macrostate may be defined as defined by the macroscopic properties of the system, such as temperature, pressure, volume, etc.
Microstate may be defined as the arrangement of each molecule in the system at a particular instant. It governs the internal arrangement of particles in a system. While macrostate is the possible outcome that governs the external arrangement of particles in the system in a definite way.
Therefore, Macrostates and microstates may be defined on the basis of their properties and characteristics.
