Answer:

If they produce an offspring that is fertile

Answer:

A

Explanation:

Producing an offspring can occur between related but different species, often called "hybrids."

Hybrids cannot have offspring, meaning they are infertile, so it's not B. Very simply put, the reproduction system is closed unless (sometimes) hybrids mate with each other

To be the same species, they need to have offspring that is fertile. Fertile just means you can reproduce.

Based on the given data, mean is 0.352, range is 0.86, median is 0.31, interquartile range is 0.28, mode is 0.12 and 0.24, and standard deviation is 0.81.

A data set is a particular number of data given in any order.

The measurements for 13 children are: 0.10, 0.25, 0.50, 0.4, 0.12, 0.12, 0.24, 0.24, 0.31, 0.36, 0.42, 0.55, 0.96.

By rearranging the data set in ascending order we get:

(0.10, 0.12, 0.12, 0.24, 0.24, 0.25, 0.31, 0.36, 0.4, 0.42, 0.50, 0.55, 0.96.)

1. mean

= (0.10 + 0.25 + 0.50 + 0.4 + 0.12 + 0.12 + 0.24 + 0.24 + 0.31 + 0.36 + 0.42 + 0.55 + 0.96)/13

= 4.57/13

= 0.352

2. range

= (0.96 - 0.10)

= 0.86

3. median = 0.31

4. Here, median of the first half of the data set is

= Q₁

= (0.12 + 0.24)/2

= 0.18

Again, median of the second half of the data set is

= Q₃

= (0.42 + 0.50)/2

= 0.46

The interquartile range

= (Q₃ - Q₁)

= (0.46 - 0.18)

= 0.28

5. mode = 0.12, 0.24

6. Standard deviation is

= √[(x₁ - X)² + (x₂ - X)² + (x₃ - X)² + (x₄ - X)² + (x₅ - X)² + (x₆ - X)² + (x₇ - X)² + (x₈ - X)² + (x₉ - X)² + (x₁₀ - X)² + (x₁₁ - X)² + (x₁₂ - X)² + (x₁₃ - X)²]

Here, x₁, x₂,......, x₁₃ are given data set in ascending order.

X = mean of the given data set.

Therefore, standard deviation is

= √[(0.10 - 0.352)² + (0.12 - 0.352)² + (0.12 - 0.352)² + (0.24 - 0.352)² + (0.24 - 0.352)² + (0.25 - 0.352)² + (0.31 - 0.352)² + (0.36 - 0.352)² + (0.40 - 0.352)² + (0.42 - 0.352)² + (0.50 - 0.352)² + (0.55 - 0.352)² + (0.96 - 0.352)²]

= √[.064 + 0.054 + 0.054 + 0.013 + 0.013 + 0.01 + 0.0018 + 0.00006 + 0.0023 + 0.0046 + 0.023 + 0.039 + 0.37]

= √(.6488)

= 0.81

K+ and aOH_ ions are how KOH decomposes. The basicity is influenced by the OH- ions. They have a 1M I concentration, the same as KOH. [OH-]=1 M

A disinfectant used to clean surfaces, hands, and skin is potassium hydroxide. Lye, commonly known as potassium hydroxide, is an inorganic substance with the chemical formula KOH. It is sold in a variety of forms, including pellets, flakes, and powders. Potassium hydroxide, sometimes known as caustic potash, is an inorganic chemical with the formula KOH. KOH is a typical strong basic, along with sodium hydroxide. It has numerous industrial and specialised uses, the majority of which make use of its caustic properties and acid reactivity.

KOH is a typical food ingredient that is utilised in the production of cocoa, chocolate, and soft beverages. It has several qualities, including thickening and stabilising effects in dishes like ice cream. Additionally, KOH makes baked foods like pretzels crispier. It can be used as a preservative in food. Potassium hydroxide is a stabiliser, thickening agent, and pH adjuster in food. Based on the observance of various good manufacturing practise conditions of use, the FDA has determined that this ingredient is generally safe as a direct human food ingredient.

pOH is the negative logarithm of the compound OH; therefore, pOH is -log1, which equals 0. In light of typical settings of 25 degrees Celsius, pH is therefore 14-pOH, or 14. So that is as simple as a solution at 25 degrees can be.

The P site

Explanation:

The P site holds the tRNA with the growing polypeptide chain. The E site serves as a threshold. It holds the tRNA without its amino acid, which is then released by ribosome.

Biomagnification refers to the process by which toxins or other harmful substances become more concentrated as they move up the food chain. It occurs when a substance enters an ecosystem and is taken up by small organisms, which are then consumed by larger organisms. Each time an organism is consumed, the substance is concentrated in the body of the larger organism, leading to higher and higher levels of the substance in the organisms at the top of the food chain.

For example, imagine a fictional substance called "X" is released into a lake. The "X" is taken up by small aquatic plants, which are then consumed by small fish. The small fish are then consumed by larger fish, and so on, up the food chain. By the time the substance reaches the top predator in the ecosystem, such as an eagle, the concentration of "X" is much higher than it was in the small aquatic plants at the bottom of the food chain.

The sentence "We learned that the solution to pollution is not dilution" relates to biomagnification because it highlights the idea that simply diluting a pollutant by spreading it out over a larger area does not necessarily make it less harmful. Instead, it may just lead to the pollutant being taken up by more organisms, leading to higher levels of the pollutant in the food chain, and potentially more harm to the ecosystem and the organisms living in it.

Mycorrhizae is an adaptation that enhances the uptake of water and minerals by roots.

Mycorrhizae are the associations that exist between fungi and roots.

In around 90% of all terrestrial plants, these symbiotic relationships can be discovered.

A root-like structure and a network of mycelium that spreads into the soil outside of the tree roots make up the mycorrhizal fungi.

By taking in nutrients, this mycelium then transfers those nutrients back towards the host plant.

The absorption surface area of the root system grows as a result. The plant can get more moisture and nutrients because its mycorrhizae, or roots, are significantly larger. This is crucial for phosphorus uptake, which is one of the main nutrients that plants need.

Hypertonic cells contain more water than their surroundings. A cell is hypotonic if it contains less water than its surroundings. If the cell has the same amount of water, it will be isotonic.

If the cell has more water than its surroundings, it is hypertonic (think of hyper as having a lot of sugar). The cell will desire to release water. The cell may shrivel or shrink as a result of this. If a cell has less water than its surroundings, it is hypotonic (think hippos). They enjoy eating. The cell will absorb water, which may cause it to enlarge, swell, or even explode. If the cell has the same amount of water/proportion of water to other components, nothing will happen and the cell will be isotonic. (Think solitary, without any interactions with other objects.)
