The allele frequency of B is 0.54 and the allele frequency of b is 0.46, and total 49.68% of the scorpions in the population are heterozygous.
To determine the allele frequencies, we can use the Hardy-Weinberg equation: p² + 2pq + q² = 1, where p represents the frequency of the dominant allele (B) and q represents the frequency of the recessive allele (b). We can estimate p and q using the proportions of individuals with each phenotype (yellow and brown).
Let's start by calculating the total number of scorpions;
Total scorpions = 96 (yellow) + 702 (brown) = 798
Next, we can calculate the frequency of the dominant allele (B) as follows;
p² + 2pq + q² = 1
where p² represents the frequency of BB individuals (brown-brown), 2pq represents the frequency of Bb individuals (brown-yellow), and q² represents the frequency of bb individuals (yellow-yellow).
Since brown (B) is dominant over yellow (b), we can assume that all brown individuals are either BB or Bb, while all yellow individuals are bb. Therefore, we can simplify the equation as follows;
p² + 2pq = 1
where p² represents the frequency of BB individuals and 2pq represents the frequency of Bb individuals.
We can estimate the frequency of Bb individuals by dividing the number of brown scorpions by the total number of scorpions;
2pq = 702/798 = 0.88
To solve for p, we can use the fact that p + q = 1. Rearranging this equation, we get;
p = 1 - q
We can substitute this into the equation for 2pq to get:
2(1-q)q = 0.88
Expanding and simplifying, we get;
2q - 2q² = 0.88
Rearranging, we get a quadratic equation;
2q² - 2q + 0.88 = 0
Using the quadratic formula, we get;
q = 0.46 or q = 0.76
Since q represents the frequency of the recessive allele (b), we can discard the solution q = 0.76 because it is greater than 0.5 (which would mean that the dominant allele, B, has a frequency of less than 0.5, which is not possible if brown is dominant). Therefore, the frequency of recessive allele (b) is q = 0.46, and the frequency of dominant allele (B) is p = 1 - q = 0.54.
So the allele frequency of B is 0.54 and the allele frequency of b is 0.46.
To calculate the percentage of heterozygous individuals (Bb), we can use the formula;
2pq x 100%
Substituting the values we found earlier, we have;
2pq = 2 x 0.54 x 0.46
= 0.4968
Therefore, the percentage of heterozygous individuals is;
0.4968 x 100% = 49.68%
So, approximately 49.68% of the scorpions in the population are heterozygous.

Answer:
Here, I got u homie!
Explanation:
Photosynthesis is the process through which green plants and other specific living organisms utilize light energy to convert water and carbon dioxide in to simple sugars. Through photosynthesis, green plants are able to manufacture their own food which is essential for their growth.

When organisms
they increase in size.
Answer:
The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.
Explanation:
A cell contains the structure shown below that contains chlorophyll and is the site of photosynthesis. What
other cell structure that is not found in all eukaryotic cells, is likely to be found in this cell?
A. Mitochondria
B. Cell Membrane
C. Cell wall
D. Cytoplasm
The cell wall is found in plant cells but is absent in animal cells. Therefore, option C is correct.
What is a cell wall?Cell walls are a specific type of extracellular matrix that covers every plant cell. Many of the traits that set plant cells apart from animal cells are caused by the cell wall.
Plant cells have a cell wall that surrounds their plasma membrane and offers tensile strength as well as defense against osmotic and mechanical stress. Additionally, it enables the development of turgor pressure or the pressure of the contents of the cell against the cell wall.
The pectin polysaccharide matrix, which is highly cross-linked, contains a matrix of cellulose microfibrils and cross-linking glycans that make up the cell wall. Lignin may accumulate in secondary cell walls. Therefore, option C is correct.

Rearrange the steps of a tsunami formation in the correct order
1. two tectonic plates slide past each other underwater, causing a large movement of water
2. large ocean waves form
3. large ocean waves move in all directions away from the shifting plates
4. large ocean waves slow down and increase in height as they reach the coast
Answer:
two tectonic plates slide past each other underwater, causing a large movement of water large ocean waves form .large ocean waves move in all directions away from the shifting plates .large ocean waves slow down and increase in height as they reach the coastExplanation:
Tsunamis are initiated underwater and usually happen as a result of underwater earthquakes which can be initiated when tectonic plates slide past each other.
This causes a large movement of water such that large waves form and move away in al directions from the source. As these waves approach the shore they slow down speed but this only increases their height such that when they make landfall the effect could be devastating.

How are genetic mutations passed from parent to offspring?
Answer:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.
I hope it's helpful!
Answer:
★ Mutated gametes (sex cells) fuse to create offspring.
Genetic mutations or germline mutations can be defined as a permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other when a mutated sperm or mutated oocyte (gametes) get fertilized with another oocyte or sperm.
A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, a single-celled zygote divides and produces all of the cells in that organism.

D. Euglena and volvox contain both chloroplasts and eyespots.
What are protists?
Protists are single-celled microorganisms that belong to the kingdom Protista. They are unicellular organisms that are not classified as bacteria, fungi, or animals, and are the simplest of the eukaryotes (organisms with a true nucleus and other membrane-bound organelles). Protists are found in a wide variety of habitats, from freshwater to marine environments, and are important for their role in the food chain, as well as for their impact on human health.
Protists come in a wide range of shapes and sizes, from amoeba-like organisms that can change shape, to algae with chloroplasts, to parasites that can cause diseases in humans and other animals. Some protists can move on their own, while others are immobile. Some can reproduce asexually, while others reproduce sexually. Despite their diverse forms and functions, all protists are considered to be part of the same kingdom because of their shared characteristics and evolutionary relationships.

Five eggs hatched, and one egg did not hatch.
One of the chicks disappeared.

Three of the chicks learned to fly, and another one disappeared.
What part of natural selection did Ronald observe?
adaptation
overproduction
selection
variation
Answer:
B. Overproduction
Explanation:
Overproduction is one of the main part of natural selection whereby an organism reproduces more offspring, of which only a few would be able to survive given the environmental condition amd factors that would be against the survival of the offspring to maturity.
From Ronald observation, we can see that the bird produces more eggs than would survive. Only 3 of the chicks survived.

Hydrophobic interactions are the basis for Sudan tests. Explain how hydrocarbons in lipids interact with polar surroundings
Answer and Explanation:
Lipids are non-polar molecules, so they do not interact preferentially with polar molecules but they can interact with each other. In a polar medium, such as water, the hydrocarbons in lipids aggregate each other, in order to minimize contact with surrounding polar molecules. The interaction between non-polar solutes with polar surroundings exclusion is called hydrophobic interaction.
