Which is the MOST accurate statement about the heating curve and energy? Responses

Answers

Answer 1

Moving from A to C the temperature and the kinetic energy increases. As the temperature of a substance increases, the movement or kinetic energy also increases.

What is kinetic energy?

An item possesses kinetic energy when it is in motion. A force must be applied to an item in order to accelerate it. Using force needs us to perform work. After the work is completed, energy is transferred to the item, and the thing moves at a new constant speed.

Alternatively, if work is done on an item by providing a net force, the object accelerates and accumulates kinetic energy.

Answers

The ability to read a DNA template from 3' to 5' is required for DNA replication, transcription, and translation.

According to the Central Dogma of Molecular Biology, DNA creates RNA, which creates proteins. The process of copying DNA to RNA is known as transcription, and the process of using RNA to make proteins is known as translation.

The opening of the double helix and separation of the DNA strands, priming of the template strand, and assembly of the new DNA segment are the three major steps in replication.

DNA replication necessitates the action of three major enzymes, each with a distinct role: Helicase is responsible for unzipping and unwinding the DNA molecule. DNA polymerase adds a new complementary strand of DNA to each of the original helicase-separated halves.

Hypothesize how photosynthesis can affect these changes, explain in 3 to 5 sentences

Answers

The process of the formation of food by trapping the sunlight with the help of chloroplast is called photosynthesis.

These are the following which are used in process photosynthesis:-

-Carbon dioxide

-Water

-Sunlight

Photosynthesis is greatly dependent on the amount of carbon dioxide concentration in the atmosphere because photosynthesis is the process where carbon dioxide gas is used in large amounts.

If the vegetation occurs higher in the season, the decrease will occur in the carbon dioxide concentration of the atmosphere while on the other hand, if less vegetation occurs then there is a higher amount of carbon dioxide concentration in the atmosphere.

Hence, the larger the amount of carbon dioxide more the yield from photosynthesis. In some cases, the high amount of carbon dioxide also acts as a poison.

Genetic variation among humans is relatively small when compared to other species. Where in the human genome does most of the diversity occur?.

Answers

Due to the common ancestry of all humans, only a small number of variants have large frequency differences between the population. Human ancestral lineages are relatively young compared to other species.

sequences coding for tRNA in homeotic genes in mitochondrial DNA in single nucleotide polymorphisms. Human genetic diversity is substantially less than that of many other species, including our closest evolutionary relative, the chimpanzee. Genetic diversity is a function of the age of a population, the amount of time over which mutations accumulate to generate diversity, and its size. Now, evolutionary geneticists have shown that our ancestors lost much of their genetic diversity in two dramatic bottlenecks that slashed the population of modern humans when they left Africa between 60,000 and 50,000 years ago. Small populations tend to lose genetic diversity faster than large populations due to genetic drift from stochastic sampling error. This is because some versions of a gene can be lost due to chance, and this is more likely to happen when populations are small.

calculate the free energy change for translocating a proton out of the mitochondrial matrix, where ph matrix

Answers

Protons are pumped out of the mitochondrial matrix into the intermembrane space.

Where is the mitochondrial matrix found?The inner and outer membranes of mitochondria define three compartments within the organelle, each with its distinct role and corresponding protein components. The innermost compartment, surrounded by the inner membrane, is the mitochondrial matrix.Chemiosmosis can be described as movement of ions across a selectively permeable membrane, down their electrochemical gradient. It occurs during the cellular respiration within mitochondria and it is involved in ATP synthesis (oxidative phosphorylation via ATP synthase).Electrons from electron carriers (NADH and FADH) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.  H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP.pH is usually calculated by the negative log of the H+ ions in a solution. The H+ ions are calculated in mols/Liter; Therefore a solute with a higher concentration of hydrogen ions has a lower pH. The difference between one pH to the next is 10 times fold the number of H+ ions.

how at least 2 different body systems work together to maintain homeostasis in your body if you are out in cold weather.

Answers

Different body systems work together to maintain homeostasis in the human body if you are out in a cold weather.

How does body systems work to maintain homeostasis in your body if you are out in cold weather?

Cardiovascular, urinary, and lymphatic systems help the body control water balance. The cardiovascular and lymphatic systems transport fluids in the body and help sense solute and water levels and regulate pressure. If the water level goes high, then the urinary system produces more dilute urine to help eliminate excess water. If the water level gets low, then more concentrated urine is produced so the water is conserved.

Cardiovascular, integumentary, respiratory, and muscular systems work together to help the body maintain stable internal temperature. If body temperature increases, then blood vessels in the skin dilate, allowing more blood to flow near the surface of the skin. This results in heat dissipation through the skin and in the surrounding air. The skin produces sweat if the body gets too hot and when sweat evaporates, it helps to cool the body.

A population of butterflies has an intrinsic rate of increase of 0.64 but a growth rate of 0.36.
Calculate the carrying capacity of the butterflies when they start with 30 of them.

Answers

Answer:

-2.28

Explanation:

The intrinsic rate of increase is the maximum rate of population growth that can be sustained by a species in the absence of limiting factors, such as competition for resources or predation. The growth rate is the actual rate of population growth that is observed in a population. The carrying capacity is the maximum population size that can be sustained by a given environment.

To calculate the carrying capacity of the butterfly population, we need to use the formula:

K = r / (K - r)

Where K is the carrying capacity, r is the intrinsic rate of increase, and K is the growth rate.

In this case, the intrinsic rate of increase is 0.64 and the growth rate is 0.36. Plugging these values into the formula, we get:

K = 0.64 / (0.36 - 0.64)

K = 0.64 / (-0.28)

K = -2.28
