HELP FAST PLEASE. Vacuoles in different organisms and cell types typically have different compositions and functions. Which of the
following pairs are most similar in composition and function?
•central vacuoles in plant cells and food vacuoles in amoebas that store sugar
•contractile vacuoles in unicellular eukaryotes and central vacuoles in plant cells
•contractile vacuoles in unicellular eukaryotes and small storage vacuoles in plant cells
•food vacuoles in amoebas and lytic vacuoles in plants that contain hydrolyzing enzymes

The rate of function of enzyme A can be increased by decreasing the pH by adding an acid.

As the temperature increases, enzyme activity generally increases due to faster molecular movement and higher collision rates between the enzyme and substrate.

However, beyond the optimal temperature for each enzyme, the activity starts to decline rapidly.

Enzymes have an optimal pH range in which they function most effectively. Going beyond or below this pH range can impact the enzyme's structure and alter its ability to bind to the substrate.

Neurons are electrically excitable cells that transmit information throughout the nervous system. They are the basic building blocks of the nervous system and perform a variety of functions, including receiving and sending signals, processing information, and controlling movement.

The nervous system is responsible for coordinating the body's activities and responding to its environment. without neurons, the nervous system would not be able to function properly. Neurons are essential for survival and play a vital role in our health and well-being.

Answer:

The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

They are termed dominant and Recessive, for the dominant allele typically masks the expression of the other allele when they are both located in the same cell.

Every gene in a species that reproduces sexually, including humans and other animals, has two copies. The two copies, which are referred to as alleles, may differ slightly from one another. The differences can alter protein expression or produce variations in the produced protein: when, where, and in what quantities protein is produced. Proteins influence traits, so varieties in protein movement or articulation can deliver various phenotypes.

The relationship between two gene versions is referred to as dominant. Each parent gives an individual two copies of each gene or allele. One allele will be expressed if a gene has different alleles; It is the most common gene. Masked is the effect of the other allele, which is called recessive.

The stage of cell respiration that is being shown above is oxidative phosphorylation. During this stage, the transport of electrons is coupled to the generation of an electrochemical gradient.

Cellular respiration can be defined as a series of metabolic reactions by which aerobic cells generate energy in the form of ATP.

Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.

During oxidative phosphorylation, the transport of electrons across the mitochondrial membrane is coupled to the generation of an electrochemical gradient, which is then used to generate ATP by an ATP synthase as shown in the figure.

The table Paramecium Contractile Vacuole Contractions which correctly describes the bars on a bar graph representing the data is the bars range from tallest for very high concentration to shortest for very low concentration.

The data in the table records the number of contractions per minute of a paramecium's contractile vacuole in response to different salt concentrations in the surrounding environment.

A bar graph representing this data would have five bars, one for each level of salt concentration.

The bars would vary in height according to the number of contractions per minute, with the tallest bar representing the highest salt concentration and the shortest bar representing the lowest salt concentration.

Therefore, the correct statement describing the bars on the bar graph would be: "The bars range from tallest for very high concentration to shortest for very low concentration."

This statement accurately describes how the height of the bars would vary based on the data in the table.

The other statements do not accurately represent the data or the trends observed in the table.

Explanation:

The correct answer is option A. Whales, bats, and humans share a common ancestor.

This is because all three species have descended from the same type of ancestral mammal, evolving over time to take on different forms and characteristics.

For example, whale ancestors required more food than could be found on land, so they evolved features that could allow them to survive in the water. Similarly, bats evolved their wings to enable them to fly and humans evolved bipedalism, allowing them to walk on two feet.

Mutations are also a major factor in the evolution of species. These happen when the genetic code of an organism changes, resulting in a new version of a particular trait. For example, viruses mutate to acquire the best-adapted hemagglutinins throughout their evolution.

Three areas each with the largest natural increase are as follows: Zhytomyr, Kyivska, and Mykolayivska.

Three areas each with the smallest natural increase are as follows: Vinnytsia, Chernivtsi, and Khmelnytska.

Since most of the areas had a negative natural increase, it indicates that more people were dying than are being born.

When there are more deaths than births in a population over a given period of time, a net fall in population size results, this is known as a negative population increase or population decline.

Emigration, in which people leave a region and reduce the local population, is another factor that can cause this.

The sides of the backbone of DNA are made of the other two molecules, 1. Sugar  

2. Phosphate.

The DNA backbone and the DNA bases are the two basic structural regions of a DNA molecule. Recall that nucleotides are the building blocks of all DNA molecules. A DNA molecule's one nucleotide is made up of a phosphate group, the pentose sugar deoxyribose (which has five carbons), and a nitrogenous base (adenine, thymine, guanine, cytosine). A DNA molecule is made up of a number of these nucleotide monomers that are connected by phosphodiester linkages. The base region of a DNA molecule is made up of nitrogenous bases, but the backbone of a DNA molecule is made up of phosphate groups and deoxyribose sugars; as a result, the backbone of DNA is made up of pentose sugars. The base portion of the molecule includes adenine. There are no hexose (six-carbon) sugars in DNA. Each nucleotide molecule has one nitrogen base, one sugar group, and one phosphate group.
