Complete the t-chart by categorizing each environmental factor as something that would most likely increase or decrease genetic variation. some answers will fit in both columns depending on the situation. predator-prey relationships decreases, competition decrease, toxins increase and decrease, new habitat decrease and increases, disasters decrease, increased food source increase.

Genetic variation are basically the alterations in the DNA sequences between the individuals who are a part of a population. Variation basically occurs in the germ cells, that is, sperm as well as the egg, and also occurs in somatic as well as all the other cells.

The number of different sources of genetic variation basically include mutation as well as genetic recombination. Mutations are considered as the ultimate sources of the genetic variation, but mechanisms, such as genetic drift also contribute. Due to it, there is a decrease in the predator-prey relationship as well as in competition and disasters which increases the food sources.

With the aid of carbon dioxide and water, green plants and some other species employ the process of photosynthesis to create food.

Green plants, algae, and some microorganisms use the process of photosynthesis to create food from light, carbon dioxide, and water. It primarily takes place in chloroplasts in plants, where it serves as a means of converting light energy into chemical energy in the form of organic compounds like glucose that can be stored for use later.

The light-dependent reactions and the light-independent reactions (sometimes referred to as the Calvin cycle) are the two primary phases of photosynthesis. Light energy is collected by pigments like chlorophyll in the light-dependent processes and transformed into chemical energy in  form of   NADPH and ATP.

Then, in the light-independent reactions that take place in the stroma of the chloroplasts, these molecules are utilised to create organic compounds.

In general, photosynthesis is crucial for life on earth because it creates the oxygen we breathe and forms the basis of the food chain for all living things.

As it removes carbon dioxide from the atmosphere and transforms it into organic compounds that may be long-term stored, it is also an essential step in the process of reducing the consequences of climate change.

The Solar System consists of the Sun with eight planets orbiting it.  The four inner planets are those closest to the Sun .They are Mercury, Venus, Earth, and Mars. They are smaller and composed of metals and rocks and hence are dense. The four outer planets  are Jupiter, Saturn, Uranus, and Neptune. They are larger and mostly made of gases, so the overall density is low A planet's density is related to its composition.

Mercury is the smallest in size. Earth and Venus are almost the same size, whereas Mars is about half their size.

According to the nebular hypothesis, Uranus and Neptune exist in a region where the density of the solar nebula is reduced and longer orbital times is longer . The two are  thought to have formed in orbits near Jupiter and Saturn, where more material was available, and to have migrated outward to their current positions over hundreds of millions of years.

The standard deviation of the distribution is given as 17.15

Assuming that the distribution of IQ scores approximates a normal curve with a mean of 100, we can use the information given to find the standard deviation (σ) of the distribution.

First, we know that the IQ scores above 115 are considered superior, which means that the area under the normal curve to the right of 115 is approximately 0.15 (since approximately 15% of the population have IQ scores above 115).

Next, we know that approximately 1% of the population have IQ scores above 140. Since the distribution is assumed to be normal, we can use the properties of the normal distribution to find the z-score corresponding to the 99th percentile (since 99% of the population have IQ scores below 140).

Using a standard normal table or calculator, we find that the z-score corresponding to the 99th percentile is approximately 2.33.

We can then use the formula for z-score:

z = (x - μ) / σ

where z is the z-score, x is the IQ score, μ is the mean IQ score, and σ is the standard deviation of the IQ scores.

Plugging in the values we know, we get:

2.33 = (140 - 100) / σ

Solving for σ, we get:

σ = (140 - 100) / 2.33

σ ≈ 17.15

Therefore, the standard deviation of the IQ scores is approximately 17.15.

Explanation:

The two methods that allow fish to maintain water balance in saltwater are pumping out salt through the gills and absorbing water into the body by osmosis.

In saltwater, the concentration of dissolved salts is higher in the surrounding water than in the fish's body cells. To maintain water balance, fish have developed two main methods:

1. Pumping out salt through the gills: Fish possess specialized cells in their gills that actively pump out excess salts from their bodies. This process helps maintain a lower salt concentration within the fish's body, preventing dehydration and maintaining water balance.

2. Absorbing water into the body by osmosis: Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. Fish have a protective layer of skin that allows water to be absorbed into their bodies while preventing the entry of excessive salts.

By absorbing water through their skin, fish replenish the water lost to the surrounding saltwater, helping to maintain their internal water balance.

These two mechanisms work together to enable fish to survive in saltwater environments. By actively pumping out salts and absorbing water, fish can regulate their internal salt concentration and prevent dehydration, ensuring their overall water balance is maintained.

● maintain its integrity.

Answer:

Heterozygous alleles are called silent carriers of a trait because they carry two different alleles for a particular gene, but only one allele is expressed in the phenotype, while the other remains "silent." The expressed allele is usually dominant, while the silent allele is usually recessive. This means that the individual carrying the heterozygous allele will not show the recessive trait, but they can still pass it on to their offspring.

If two heterozygous parents each pass on a recessive allele, their offspring has a 25% chance of inheriting two recessive alleles and showing a recessive phenotype. In this case, the heterozygous parents are carriers of the recessive trait, but do not show it in their phenotype.

Therefore, the correct answer is: If two heterozygous parents each pass on a recessive allele their offspring will show a recessive phenotype.
