In September the earth will be experiencing  an equinox

Equinoxes occur between March and September. When the Sun's rays strike the equator at midday and at a 90° angle, it is considered an equinox.  It stands for the idea that day and night have equivalent lengths. The sunset and dawn are separated by 12 hours everywhere on Earth. One may observe how quickly the sunset and dawn hours shift throughout the day the farther one goes from the equator.

Whereas, solstices occur in June and December. The contrary is visible close to the solstices. For a few days, both the sunset and sunrise appear to be constant. Over the course of the year, the time of day when the sun is directly overhead where one lives also gradually changes.

Explanation:

A wavelength, when drawn like this, is between two points in the exact same spot of the wave, but in different positions. Here, C is the middle when the wave is going "down" into the trough. The next point at this position is point E, giving us our answer.

The frequency of the dominant allele (p) is approximately 0.982 and the frequency of the recessive allele (q) is approximately 0.018.

To determine if the population is in Hardy-Weinberg Equilibrium, we need to compare the observed genotype frequencies to the expected genotype frequencies under the assumptions of the Hardy-Weinberg Equilibrium.

Let's define our variables:

Under the assumptions of Hardy-Weinberg Equilibrium, the expected genotype frequencies are:

We can use the following equation to calculate the expected genotype frequencies:

p^2 + 2pq + q^2 = 1

Now let's plug in the numbers we have:

Total number of individuals (N) = 552

Number of individuals with purple petals (n) = 546

The frequency of the dominant allele (p) can be calculated as the square root of the frequency of individuals with purple petals:

p = √(n/N) = √(546/552) ≈ 0.982

The frequency of the recessive allele (q) can be calculated as 1-p:

q = 1 - p ≈ 0.018

Now let's calculate the expected genotype frequencies:

p^2 = (0.982)^2 ≈ 0.964

2pq = 2 x 0.982 x 0.018 ≈ 0.035

q^2 = (0.018)^2 ≈ 0.0003

The expected genotype frequencies are:

PP: 0.964 x 552 ≈ 531

Pp: 0.035 x 552 ≈ 19

pp: 0.0003 x 552 ≈ 0.2

Now let's compare the observed genotype frequencies to the expected genotype frequencies:

Number of individuals with genotype pp: 552 - 546 = 6

We don't have enough information to calculate the observed genotype frequencies for PP and Pp, so we cannot directly compare the observed and expected genotype frequencies.

However, we can check if the conditions of Hardy-Weinberg Equilibrium are met:

If all these conditions are met, then the population is in Hardy-Weinberg Equilibrium. In this case, we can assume that the population is in Hardy-Weinberg Equilibrium since we don't have any reason to believe that the conditions are not met.

Answer:

Boreal forest is among the largest terrestrial biomes on earth in which minerals in the soil most rapidly depleted.

The sentence that best describes the temperatures of a city located along a windward coast is C.Cooler summer temperatures than an inland location at the same latitude.

A city on a windward coast experiences cooler summer temperatures than an area inland at the same latitude.

In comparison to an inland site at the same latitude, a city positioned along a windward coast will experience (b) lower summer temperatures. This area's predominant breeze originates from the lake, which will always have a moderating effect (both warmer in the winter and cooler in the summer). Climate, salt intake, hormone levels, carbohydrate intake, degree of physical activity, and some substances like alcohol and caffeine can all have an affect on total body water content.

Temperature is crucial because it affects the chemistry of water. At greater temperatures, chemical reactions typically proceed more quickly. Higher temperature water, especially groundwater, can dissolve more minerals from the underlying rock and will consequently have a higher mineral content.

Therefore, option C is correct.

Answer:

What is the cell theory? It has three main parts:

1. All living things are made up of cells.

2. Cells are the basic building blocks of life.

3. All cells come from preexisting cells created through the process of cell division.

As science evolved, three more components were added to the theory. Some biology classes don’t require you to know these parts of the cell theory because they weren’t part of the original definition, but it’s still useful to be aware of them:

4. Energy flow occurs within cells.

5. Hereditary information is passed from cell to cell.

6. All cells have the same basic chemical composition.

So what does the cell theory actually mean? Let’s break it down. The first part of the cell theory states that all living things are made up of cells. Anything that’s alive, from bacteria to plants to humans, is composed of cells. And what are cells? The literal definition is a cell is a group of organelles surrounded by a thin membrane.

The cell theory definition states that cells are the building blocks of life. Cells both make up all living things and run the processes needed for life. Your hair, skin, organs, etc. are all made up of cells. In fact, each person is estimated to be made up of nearly 40 trillion cells! Each part of a cell has a different function, and your cells are responsible for taking in nutrients, turning nutrients into energy, removing waste, and more. Basically, everything your body does, it does because cells are directing the action!

Incus is the bone which is not connected to the pelvis directly.

The pelvis is the lower part of the torso, between the abdomen and thighs (sometimes called the pelvic region), with an implanted skeleton.

Incus (inclusive) or anvil is the bone in the middle ear. The small anvil-shaped bone is one of the three ossicles in the middle ear.

The incus receives vibrations from the laterally connected malleus and transmits them to the medial stapes.

Incus Bone has several basic regions. One of its surfaces, called the head, articulates with the knuckle of the malleus. The anvil also has two extensions known as the long crus and the short crus.

Long crus have lenticular projections at the ends. This is the hooked part of the incus that articulates with the head of the stapes.

The short crus is attached to the posterior wall of the middle ear cavity where the ossicles are located. The centre of the incus is also called the body.

The dust bowl refers to a period of drought during the civil war.

The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of both natural factors and manmade factors.

Economic depression coupled with extended drought, unusually high temperatures, poor agricultural practices and the resulting wind erosion all contributed to making the Dust Bowl.

The Dust Bowl, also known as “the Dirty Thirties,” started in 1930 and lasted for about a decade, but its long-term economic impacts on the region lingered much longer.
