Ciliated cells have tiny hairs on them that are called cilia. These cilia are hair-like structures that extend from the surface of the cell and are capable of rhythmic movements. The movement of cilia is important in various biological processes such as the movement of mucus in the respiratory tract, the movement of eggs in the female reproductive system, and the movement of sperm in the male reproductive system.

The next generation of pea plants has 552 plants, 546 have purple petals. Is the
population in Hardy-Weinberg Equilibrium? Solve for p and q.
Answers
The frequency of the dominant allele (p) is approximately 0.982 and the frequency of the recessive allele (q) is approximately 0.018.
What is the population frequency?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:
p: the frequency of the dominant allele (in this case, the allele for purple petals)q: the frequency of the recessive allele (in this case, the allele for white petals)Under the assumptions of Hardy-Weinberg Equilibrium, the expected genotype frequencies are:
p^2 for the frequency of homozygous dominant individuals (PP)2pq for the frequency of heterozygous individuals (Pp)q^2 for the frequency of homozygous recessive individuals (pp)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: unknownNumber of individuals with genotype Pp: unknownNumber 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:
Random mating: We don't have information on this, so we assume that mating is random.No mutation: We assume that there are no new mutations in the population.Large population size: With 552 individuals, the population size is reasonably large.No gene flow: We assume that there is no migration of individuals into or out of the population.No natural selection: We assume that there is no differential survival or reproduction based on the genotype.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.

Does anyone know what the electrons and protons are when the mass changes to 135 on caesium?
Answers
Answer:
Protons are still going to be 55 and electrons will be 55.
Explanation:
The number of electrons and protons is the same unless the atom is an ion, which we can assume it isn't. The only thing that affects the total atomic mass is what's inside the nucleus (protons and neutrons), and if the number of protons stayed the same (or the element did not change), then the only thing that changed was the neutrons, therefore the protons and electrons are still the same as they would be if it were a normal Cesium atom.

Please choose the correct answer from the following choices, and then select the submit answer button.
Answer choices
switching all their compact fluorescent bulbs to incandescent bulbs
buying an Energy Star-rated clothes dryer
installing a tankless water heater
add insulation in the roof space
Answers
Switching all their compact fluorescent bulbs to incandescent bulbs would NOT result in a reduction in energy costs. Option a is correct.
Switching all compact fluorescent bulbs to incandescent bulbs would not result in a reduction in energy costs because incandescent bulbs are not energy-efficient. Compact fluorescent bulbs use 75% less energy than incandescent bulbs and last up to ten times longer, making them a much more cost-effective option. Buying an Energy Star-rated clothes dryer can also help save energy and reduce costs.
Energy Star appliances are designed to use less energy than standard appliances, which translates to lower energy bills over time. Installing a tankless water heater can also help reduce energy costs by only heating water when it is needed. Finally, adding insulation in the roof space can help keep a home warmer in the winter and cooler in the summer, reducing the need for heating and air conditioning, and thus reducing energy costs. Option a is correct.

Part C - Follicles Kate thought it was interesting that, after the release of a mature oocyte from the ovary, the follicle it was released from took on a new role. What happens to the follicle
Answers
Answer: The follicle assumes a new role which is:
--> the secretion of hormone PROGESTERONE and
--> OESTROGEN
Explanation:
The cycle in the female reproductive system of humans which tak s 28dayd to complete is known as menstrual cycle. At the beginning of the menstrual cycle, several primary oocytes begin to develop. Each oocyte is surrounded by actively dividing granular cells from which it receives nutrients. The whole structure is called a FOLLICLE.
A developing follicle secretes OESTROGEN.
Usually, only one of the developing follicles becomes mature to produce an ovum. As the follicle matures, it becomes filled with fluid and the oocyte is pushed to one side. Ovulation occur when there is release of an ovum from a mature follicle.
The ruptured mature follicle develops into a CORPUS LUTEUM which is a solid yellow body that secretes the hormone PROGESTERONE. This is the hormone that helps to maintain the early stages of pregnancy if fertilization and implantation of embryo occurs. In the absence of pregnancy, the corpus luteum shrivels.
In a female, several main oocytes begin to mature at the start of the menstrual cycle. Each of the oocyte is surrounded by granular cells that are actively dividing and provide it with nourishment forming a ball like mass structure. This structure is known as a follicle.
After the release of a mature oocyte from the ovary, the follicle it was released from takes on a new role and becomes the Corpus luteum.
The ruptured mature follicle after releasing the one main oocyte that develops into the egg develops into a Corpus Luteum. This structure functions in the secretion of the hormone known as progesterone.
If fertilization and embryo implantation occur, this hormone helps to maintain the early stages of pregnancy. The corpus luteum shrinks in the absence of pregnancy.

in a flowering pot, tall is dominant to short, and blue flowers is dominant to white flowers. The top with white flowers is crossed with a short plant with blue flowers. What is the chance that the offspring will be short with white flowers?
Answers
Answer:
There is a 0% chance that the offspring will be both short and white flowers.
Explanation:
For this we are going to go in and use the Punnett squares. Let´s identify the dominant and recessive genes.
Tall Flowers are Dominant - T(capital for dominance)
Short Flowers are Recessive - t(lowercase for recessiveness)
Blue Flowers are Dominant - W(Capital for dominance)
White Flowers are Recessive - w(Lowercase for recessiveness)
Let´s set up our chart with the information that we have. Its easy to draw the chart, but we need to understand the genes, and make sure that everything is okay!
There is a picture that I took of the chart on the bottom of the page. You can see the dominance of the Tall gene, and the Dominance of the Blue gene. Because none of the offspring have a chance of being short of white, that makes it impossible to have a percentage any higher than 0%.
UNLESS there is a clear mishap or genetically mutated gene in the flower. We never know! I really hope this helped!

If your immune system can't actually stop you from getting ill, then why is it beneficial? Why is it evolved to work this way, instead of simply stopping every infection in its tracks?
Answers
The inmmune system is continuouly working in the human body. While no aggresive factore attacs the body the person feels no changes, however, when certain substances, germs or other factors enter the body the inmune system is activated. This happens when the body does not recognize those factores, which are called antigens.
When the inmune system is activated a number of proesses occur inside the human body. These processes generally allow the inmune system to identify the germ and learn how to fight it, so the next time the exact germ enters the body the inmune system will have information stored on how to fight it and the response will be faster.
Therefore, the first time a person encounters a certain disease he or she gets ill until the inmune system reacts and fights it. The next time the person encounters the same disease the person probably will not get sick.
The inmune system is beneficial because it allows the body to protect itself and save the information it needs to properly fight the disease in the future.
If the information on how to fight a specific germ is not available in the genetic material of the person then he or she, in orther to gain it, will eventually have to get ill or get vaccinated.

Explain the following statement using evidence from the DNA sequences:
Mutations in the DNA change how proteins are made which leads to new and different forms of phenotypes.
Answers
A missense mutation is a Genetic alteration that causes the protein produced to encode a different amino acid at a specific location. Certain missense mutations change how the resulting protein functions.
Why do some changes in an organism's DNA sequence cause change, while others do not?While mutations always result in a change in the DNA sequence, they do not necessarily have a noticeable impact on the organism or alter the resulting protein. Since most amino acids can be encoded by two or more distinct codons, this is possible.
Can mutations be found using DNA sequencing?The ability to properly identify and characterise the majority of sequence changes makes direct DNA sequencing, in theory, the method for mutation identification with the highest degree of accuracy.

The rate at which it moved
The type of motion is the most important characteristic of a slope failure, and there are three different types of motion:
If the material drops through the air, vertically or nearly vertically, it’s known as a fall.
If the material moves as a mass along a sloping surface (without internal motion within the mass), it’s a slide.
If the material has internal motion, like a fluid, it’s a flow.

Lacy wants to design an experiment that will show ovary part of a tomato flower grows into the tomato fruit.
What is ovary for plant?The female reproductive organ present in flowering plants is the ovary. It is present in the flower's gynoecium. It is a portion of the pistil that holds the ovules and is located near the base of the sepals and petals. A single carpel or numerous carpels joined together can form the pistil.
Ovaries, as we know, are an essential component of the plant's female reproductive system. Well, the ovaries are where pollen is kept before developing into ovules and ultimately seeds. These seeds then germinate, causing the ovaries to grow and convert into fruits.
Even though the blooms are self-fertile, the pollen is nevertheless moved to the female half of the blossom by wind and the buzzing of bees' wings. The young tomato grows after fertilization, when the petals and stamens fall off.
So, Lacy will show ovary part of a tomato flower grows into the tomato fruit.
