Maiacetus is significant because of how well the skeletons were preserved. Over 90% of the bones from the male were found intact, which is almost unheard of for a specimen this old!

Their skeletons have all been found among fossils of sea-creatures which suggests they lived in the sea.

The fore-snout is starting to elongate. An elongated fore-snout is found in all modern whales and all transitional whales after Maiacetus.

Answer and Explanation:

Metabolismo: El término hace referencia a todos los cambios y las reacciones quimicas y biológicas que ocurren en cada célula del organismo y que resultas escenciales para el funcionamiento adecuado del organismo (una buena nutrición, crecimiento, reparación celular, conversion energética, etc.).

Estas reacciones ocurren a lo largo de toda la vida del organismo. Cada celula toma sustancias que luego modifica químicamente para integrarlas como nuevos componentes celulares. Algunos de estos componentes son utilizados en reacciones como la respiración celular.

El metabolismo puede ser dividido en anabolismo y en catabolismo. Durante el anabolismo suceden reacciones que consumen energía (ATP) para sintetizar moléculas complejas a partir de moléculas simples, y que son necesarias para el funcionamiento del organismo. Mientras que durante el catabolismo suceden reacciones que liberan energía al deegradar o reducir moléculas grandes en otras mas simples, para que el cuerpo pueda asimilarlas y las transforme en energia (ATP). Esta energía luego será utilizada en los procesos anabólicos.

Ejemplos:

- Respiración celular: Degradación de molécula del glucosa para liberar y obtener energía y consecuentemente, moleculas mas simples (CATABOLISMO)

- Ciclo de Krebs: Oxidación de la molécula acetil-CoA y obtención de energía en forma de ATP (CATABOLISMO).

- Digestión: Degradación del alimento para obtener elementos mas asimilables por la célula y energía (CATABOLISMO).

- Degradación de ADN y ARN (CATABOLISMO).

- Fotosíntesis: Transformación de compuestos inorgánicos en orgánicos utilizando energía solar (ANABOLISMO).

- Síntesis proteica: Utiliza aminoácidos y energía para formar proteinas necesarias para el organismo (ANABOLISMO).

- Ciclo de Calvin: Usa moléculas de CO2 para formar glucosa (ANABOLISMO).

- Gluconeogénesis: Síntesis de glucosa a partir de precursores diferentes a los  glúcidos (ANABOLISMO).

No, a change to a G would not result in a change in gene expression as the underlined C is a non-coding nucleotide and does not have any effect on gene expression.

Non-coding DNA corresponds to the portion of an organism's genome that does not code for amino acids, the building blocks of proteins. Some noncoding DNA sequences are known to play functional roles such as regulation of gene expression, whereas other regions of noncoding DNA have no known function. Other regions of non-coding DNA are important for protein assembly. By altering one of these regions, a variant (also known as a mutation) in the noncoding DNA can turn on the gene, causing the protein to be produced in the wrong place or at the wrong time. There are two types of SNPs in the coding region.Synonymous and non-synonymous SNPs. Synonymous SNPs do not affect the protein sequence, whereas non-synonymous SNPs change the amino acid sequence of the protein.

Humans cannot survive in space without a spacesuit or some form of life support system. The space environment is extremely hostile to human life for several reasons:

1. Lack of oxygen: Space is a vacuum, meaning there is no air or atmospheric pressure. Without a spacesuit, there would be no supply of oxygen for breathing, leading to rapid asphyxiation.

2. Extreme temperatures: Space is subject to extreme temperatures. In direct sunlight, temperatures can reach hundreds of degrees Celsius, while in shadowed areas, temperatures can plummet to hundreds of degrees below freezing. Without proper thermal regulation, a person would quickly succumb to either extreme heat or cold.

3. Lack of pressure: Space lacks atmospheric pressure. Exposure to the vacuum of space would cause the fluids in the human body, such as saliva, tears, and even blood, to boil and evaporate. This would lead to severe tissue damage and potentially fatal physiological effects.

4. Radiation exposure: Space is filled with high levels of radiation, including cosmic rays and solar radiation. Without the protection of a spacesuit or shielding, astronauts would be exposed to harmful doses of radiation, which can damage DNA, cause radiation sickness, and increase the risk of cancer.

Due to these factors, humans cannot survive for more than a few moments in the vacuum of space without a spacesuit or suitable life support systems. Spacesuits provide a pressurized environment, oxygen supply, temperature control, and protection from radiation, allowing astronauts to safely venture into the inhospitable conditions of space.

The Frank-Starling Law and atrial systole increase stroke volume in a healthy heart.

To answer this question, let's consider each factor and its effect on stroke volume:

An increase in heart rate: An increase in heart rate alone does not directly increase stroke volume. However, it can indirectly affect stroke volume by altering the time available for ventricular filling.

Atrial systole: Atrial systole refers to the contraction of the atria. This contraction helps to push additional blood into the ventricles, increasing the volume available for ejection during systole and therefore increasing stroke volume.

The Frank-Starling Law: The Frank-Starling Law states that the force of contraction of the ventricles is directly proportional to the initial length of the muscle fibers. When the ventricles are filled with a larger volume of blood during diastole, they stretch, resulting in a more forceful contraction during systole and an increased stroke volume.

The length-tension relationship: The length-tension relationship refers to the optimal length at which the cardiac muscle fibers generate the maximum force of contraction. When the ventricles are filled with an appropriate volume, the cardiac muscle fibers are optimally stretched, leading to a stronger contraction and an increased stroke volume.

Summation in the cardiac muscles: Summation refers to the phenomenon where subsequent contractions occur before the previous contraction has completely relaxed. This leads to a greater force of contraction in each subsequent beat and can increase stroke volume.

Therefore, the factors that act to increase stroke volume in a healthy heart include atrial systole, the Frank-Starling Law, the length-tension relationship, and summation in the cardiac muscles. An increase in heart rate alone does not directly affect stroke volume.

The amount of fluid required to bring the animal back to normal hydration status is called fluid deficit.

Fluid deficit refers to the amount of fluid that needs to be administered to an animal to restore its normal hydration status.

It represents the difference between the actual fluid content in the body and the desired fluid content necessary for optimal hydration.

Fluid deficit can occur in various situations such as dehydration, excessive fluid loss due to vomiting or diarrhea, or insufficient fluid intake.

It is important to assess and calculate the fluid deficit accurately to provide appropriate fluid therapy and restore the animal's hydration balance.

Determining the fluid deficit involves considering factors such as the animal's weight, degree of dehydration, ongoing fluid losses, and underlying medical conditions.

This calculation helps healthcare professionals, such as veterinarians or healthcare providers, determine the appropriate volume and rate of fluid administration to effectively rehydrate the animal.

By addressing the fluid deficit and providing adequate fluid replacement, normal hydration status can be restored, supporting proper physiological function and overall well-being of the animal.

The loss of voles and shrews due to a disease outbreak would likely have far-reaching and potentially cascading impacts on the local food web and ecosystem.

A food web is a diagram that shows how different species of plants and animals in an ecosystem are connected through the flow of energy and nutrients. It illustrates the many different ways in which species depend on each other for survival.

If a disease caused the populations of voles and shrews to die off, it would likely have a significant impact on the local food web. Voles and shrews are important herbivores in many ecosystems, and they are often a food source for larger predators such as owls, foxes, and snakes. If the populations of these small mammals were to decline or disappear, it could lead to a chain reaction in the food web, affecting the populations of the animals that rely on them for food.

It is also worth noting that the disappearance of voles and shrews could have indirect effects on other species in the ecosystem. For example, if these small mammals play a role in seed dispersal or in maintaining the structure of the vegetation in an area, their disappearance could lead to changes in the habitat that could affect other species.
