Fast swimming marine predators such as dolphins, sharks, and tuna, have a ______ body shape that minimizes _______ in the water.

The effect that the opening of voltage-gated potassium channels on the membrane potential is it becomes less positive and more negative. These channels allow the entry of potassium (K+) ions into the cell.

At the resting potential, the cell is more negatively charged than the outside the cell.

This negative charge is caused by the accumulation of more sodium (Na+) ions outside the cell than potassium (K+) inside the cell.

When potassium (K+) channels open, the cell becomes more negative because more positive ions leave the cell (hyperpolarized).

The first urea cycle intermediate that will contain the labeled nitrogen is citrulline.

The urea cycle (also known as the ornithine cycle) is a cycle of biochemical reactions that produces urea (NH2)2CO from ammonia (NH3). Animals that use this cycle, mainly amphibians and mammals, are called ureotelic.The urea cycle converts highly toxic ammonia to urea for excretion.[1] This cycle was the first metabolic cycle to be discovered (Hans Krebs and Kurt Henseleit, 1932), five years before the discovery of the TCA cycle. This cycle was described in more detail later on by Ratner and Cohen. The urea cycle takes place primarily in the liver and, to a lesser extent, in the kidneys.

Net primary productivity (NPP) can be defined as the amount of energy produced by autotrophs that is available for transfer to higher trophic levels.

Autotrophs, such as plants and algae, produce energy through the process of photosynthesis by converting sunlight, water, and carbon dioxide into organic compounds. This energy is then utilized by the autotrophs for their growth, maintenance, and reproduction.

However, not all the energy produced by autotrophs can be transferred to higher trophic levels, as a portion of it is consumed for their own metabolic processes. Net primary productivity is the remaining energy after these processes have taken place, which is then accessible to heterotrophs (such as herbivores) in the ecosystem.

To calculate NPP, we subtract the energy used by autotrophs for autotrophs (R) from the gross primary productivity (GPP), which is the total amount of energy produced by autotrophs. The formula for this is: NPP = GPP - R.

In summary, net primary productivity represents the energy available for transfer to higher trophic levels within an ecosystem, which ultimately determines the energy flow and the overall health of the ecosystem.

The statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false. Sporulation is a process where some bacteria transform into a dormant state called a spore. Only one spore is produced per bacterial cell during sporulation.

Bacterial sporulation is a process where some bacteria convert to a dormant state called a spore. Sporulation can occur in some bacteria species under stress conditions such as a lack of nutrients. Sporulation starts when the bacterial cell divides into two unequal-sized compartments. One compartment is the smaller forespore while the other is the larger mother cell.

The mother cell engulfs the forespore within itself and forms a spore. Only one spore is produced per bacterial cell during sporulation. These spores can survive in harsh environments and then germinate into new bacterial cells when conditions are favorable again. Therefore, the statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false.

Right: Lower pitch, longer wavelength, decreased frequency

Answer:

water

Explanation:

because i said so.

p represents the frequency of the dominant allele, it cannot be negative. Therefore, the answer is A) 0.47, which is the closest option to 0.48.

To solve this problem, we need to use the equation for the Hardy-Weinberg principle: p^2 + 2pq + q^2 = 1. This equation represents the frequency of the three possible genotypes for a given allele in a population, where p represents the frequency of the dominant allele (in this case, blue) and q represents the frequency of the recessive allele (in this case, green).
We know that q^2 = 0.28, because 28 out of 100 organisms are green. Therefore, q = sqrt(0.28) = 0.53.
Substituting this value for q in the equation, we can solve for p:
p^2 + 2pq + 0.53^2 = 1
p^2 + 2(0.53)p + 0.2809 = 1
p^2 + 1.06p - 0.7191 = 0
Using the quadratic formula, we find that:
p = (-1.06 ± sqrt(1.06^2 + 4(1)(0.7191))) / (2(1))
p = (-1.06 ± 1.02) / 2
p = -0.04 / 2 or 0.96 / 2
p = -0.02 or 0.48
Since p represents the frequency of the dominant allele, it cannot be negative. Therefore, the answer is A) 0.47, which is the closest option to 0.48.

The primary functions of whales include feeding, reproduction, communication, and migration.

Whales are primarily filter feeders or predators, depending on the species.

Filter-feeding whales, such as baleen whales, have baleen plates in their mouths that allow them to filter out small prey, such as krill or small fish, from large volumes of water.

Predatory whales, such as toothed whales, hunt and feed on various marine organisms, including fish, squid, and marine mammals.

Reproduction is another important function for whales. Most whale species have a gestation period of several months, with females giving birth to a single calf.

The calves are nursed with milk from their mothers and rely on their care for a period of time until they become independent.

Communication is vital for whales, as they rely on vocalizations to communicate with other members of their pod.

Whales produce a variety of sounds, including songs, clicks, and whistles, which serve purposes such as mating, social interactions, and navigation.

Migration is a common behavior observed in many whale species. Whales undertake long-distance migrations, often covering thousands of kilometers, to reach feeding grounds in nutrient-rich waters or to reproduce in specific breeding areas.

These migrations are driven by seasonal changes in food availability and environmental conditions.

In summary, the primary functions of whales encompass feeding, reproduction, communication, and migration, all of which are essential for their survival and successful adaptation to their marine environments.
