Answer:

water is essential for life as we know

Explanation:

Water (H2O) is essential for life (i.e. carbon-based life) because this molecule has unique chemical properties. First, water is a universal solvent that helps cells to transport and use essential molecules (e.g., oxygen and nutrients). Second, water molecules help cells to maintain their shape/structure by generating pressure within the cells. Third, the polarity of water helps the formation of phospholipidic membranes because phospholipids have polar heads that interact with water and nonpolar tails that interact with each other. Fourth, water has a high heat capacity, thereby helping to regulate the temperature in the (intracellular) environment. Finally, water molecules also have unique adhesion and cohesion properties that enable the movement of substances against gravity (adhesion) and create a surface tension (cohesion) that helps to the formation of bubbles with water.

Answer:

The base of any age group graph represents a population below the age of fifteen. ... Thus, rapid growing graph has a wider base while a slow growing population has a narrower base. a steady population graph has base approximately equal to the population age group above it.

Answer:

Okay! Had to do some research, but now I'm here.

Explanation:

So, to do this, half-life is a sort of time period where half of the starting material naturally decays into a stable element, such as uranium.

Meaning, after 17.5 days, 50 grams of that radioisotope will be left.

After 35 days (2 half-lives), 25 grams of that radioisotope will be left.

See where I'm getting at?

After 52.5 days, 12.5 grams of the radioisotope will be left.

(It's easier to create a graph, but I'm using a simple progression method to solve this.)

As such, after 70 days, 6.25  grams of that radioisotope will be left.

See? Pretty easy. Just keep adding the amount of the half-life, and divide the starting material by two!

Hope this helps!

Answer:

You can calculate by given steps.

Explanation:

A Use Equation 14.28 to calculate the half-life of the reaction. B Multiply the initial concentration by 1/2 to the power corresponding to the number of half-lives to obtain the remaining concentrations after those half-lives. C Subtract the remaining concentration from the initial concentration.

Answer:

A. Oxygen in the alveoli diffuses into the blood in the capillaries.

Answer:

The correct answer is - the production of a truncated (shortened) protein.

Explanation:

In this question, it is given that there is a transversion type of substitute mutation that causes the change in the coding region of a gene. By this transversion, there is a substitute in the last base of the UAC code of gene that codes for leucine amino acid to a stop codon.

As stop codon comes before the actual stop codon in the gene leads to terminate the translation of mRNA to the amino acid chain that results in shortened or truncated protein.

Answer:

Introduced to a new area, spreads rapidly, and displaces native species.

Explanation:

A species is invasive when they were not present in the area before, and once that they are there, they reproduce at a high peace. The fast reproduction rate, which leads to the spread of the species in the area, causes a disbalance in the ecosystem since it eats other species, which are native because they are from that area or other species' food. As a consequence, native species die or are reduced in number because the new species invaded their habitat.

An invasive species is not endemic because they are not native to that particular area. They are always external to this one.

Answer:

Number of cells killed at the end of the experiment

Explanation:

In research, the dependent variable is one whose value is dependent on another variable - a variable that is supplied by the researcher during the course of the experiment which is also known as the independent variable.

In this case, since the main objective of the research was to determine the most effective antibiotic against the E. coli, the variable that is supplied by the researcher (the independent variable) is, therefore, the different antibiotics while the variable whose value varies based on which of the antibiotics is introduced is the number of dead bacterial cells.

Therefore, the dependent variable is the number of cells killed by each antibiotic.

Answer:

gravity

Explanation:

gravity is the force that pulls substances towards the earth

Gravitational force is responsible for pulling these gaseous molecules closer to Earth’s surface.

An Atmosphere may be defined as a collection of layers that consist of several gases that surround the planet or any celestial body.

Gravitational force involves the attraction of numerous compounds as well as gaseous molecules towards the earth's surface.

Therefore, more than 50% of the gas molecules in Earth’s atmosphere are found in the troposphere layer.

Answer:

A seamount is a large geologic landform that rises from the ocean floor but that does not reach to the water's surface

Explanation:

It is able to support diversity because many deep-sea animals, such as corals and sponges spend most of their lives permanently attached to rocks. As opposed to a flat seafloor, seamounts rise off the ocean bottom and interact with water flowing around them. These water currents can wash off sediment on a seamount, exposing rocks that are ideal habitat for animals that require hard substrate to grow and attach.

Also, because these animals cannot move around to find food, they are dependent on ocean currents to bring their food to them. The strong currents running over a seamount can deliver animals living along its flanks with a constant supply of planktonic food.  Nutrients like nitrates and phosphates, which are critical to the growth of phytoplankton, are lifted from the deep to the sunlit surface waters. These nutrients fuel an explosion of planktonic plant and animal growth and attract larger animals such as whales, sharks, tunas, and seabirds to a veritable feast.

Mass/mass percent concentration means the mass of the solute/mass of the solution times 100. You know both the mass of the solute (0.870 g protein) and the mass of the solution (10.279 g solution). So divide and multiply your result by 100.  (0.870 / 10.279 * 100)

Explanation:

Extinction of the species refers to the death of the total species from the planet. The species with a slow reproduction rate and little hereditable variability habiting changing conditions will extinct first.

Many biological factors affect the survival of the organism as they play the most crucial role in the life and death of the species. The organism's reproduction rate, genetic modification and variability affect the survival of the organism.

The species that have a high rate of reproduction and high genetic variation can survive and continue their lineage when the surrounding habitat or the environment is altered or modified as they have better traits and characters.

The species in a changing environment with slow reproducing capability and very less genetic modification and variation will reduce the survival and adaptation chances of the organism and are more likely to go extinct first compared to the other organisms.

Therefore, option c, slow reproduction and less genetic variation in the species will go extinct first.

Answer:

I believe replication would not be possible, therefore the DNA would cease to help recreate cells which are essential to the human body.

Explanation:

This question by far is highly interesting, in fact it is very controversial too. However, with the sudden beginning of an actual hydrogen bond forming within nitrogenous bases, then replication would not be possible. This is so because replication relies only on nitrogenous bases rather than hydrogenous bonds. Therefore, resulting in a possible defect in the process of replicating to occur. However, if possible, I believe there might be even a chance of a mutation to occur, yet that is highly rare given the stance that the DNA molecule would not be able to pretty much do anything if that were to occur.
