Answer:
Green/Wide/Long, G-W-L- = 186 individuals Yellow/narrow/ long, gg ww L- = 186 individuals Green/wide/ short, G-W-ll = 186 individuals Yellow/narrow/ short, gg ww ll = 186 individuals Green/narrow/ long, G-wwL- = 14 individuals Yellow/wide/ long, gg W-L- = 14 individuals Green/narrow/short, G-wwll = 14 individuals Yellow/wide/ short, ggW- ll = 14 individualsExplanation:
Available data:
• One gene affecting pod color (green is dominant to yellow)
• One gene affecting pod width (wide is dominant to narrow)
• Both genes are located on chromosome 5 and approximately 7 mu away from each other.
• A third gene, located on chromosome 4, affects pod length (long is dominant to short).
• Cross: A true-breeding wild-type plant (green, wide, long pods) was crossed to a plant with yellow, narrow, short pods.
• The F1offspring were then test-crossed to plants with yellow, narrow, short pods.
• The testcross produced 800 offspring.
Cross 1:
Parental) GGWWLL x ggwwll
F1) GgWwLl
Cross 2:
Parental) GgWwLl x ggwwll
F2) N=800
To calculate the numbers of the F2 generation, we first need to calculate the frequencies of recombination and parental of the linked genes. We know that they are 7MU apart from each other. The map unit is the distance between a pair of genes for which every 100 meiotic products one results in a recombinant one.
MU = 7 means that there is 7% of recombination for genes that express color and width. This is:
MU = 7 = 7% recombination
We have two possibilities of recombination: green/narrow and yellow/wide. Each of these recombinants has half of the possibilities of occurring, so:
7 map units = 7 % of recombination in total
= % Gw + % gW
= 3.5 % + 3.5 %
Gw = 3.5% = 0.035
gW = 7%/2 = 0.035
For the parentals, we can calculate
100% - 7% = 93% of parental in total
= % of GW + % gw
= 46.5% + 46.5%
GW = 46.5% = 0.465
Gw = 46.5% = 0.465
The length gene is located in a different chromosome so it assorts independently. This is, of the gametes will be long, L, and the other 50% will be short, l.
L = 50% = 0.5
L = 50% = 0.5
Now we need to figure out how to relate these frequencies. All we need to do is to multiply the frequencies of occurrence obtained previously for linked and independent genes, for each possible phenotype. This is:
Green/Wide, GW = 0.465 Yellow/narrow, gw = 0.465 Green/Narrow, Gw = 0.035 Yellow/Wide, gW = 0.035 Long, L = 0.5 Short, l = 0.5Phenotypic frequencies:
Green/Wide/Long, G-W-L- = GW x L = 0.465 x 0.5 = 0. 2325 Yellow/narrow/ long, gg ww L- = gw x L = 0.465 x 0.5 = 0. 2325 Green/wide/ short, G-W-ll = 0.465 x 0.5 = 0. 2325 Yellow/narrow/ short, gg ww ll = 0.465 x 0.5 = 0. 2325 Green/narrow/ long, G-wwL- = 0.035 x 0.5 = 0.0175 Yellow/wide/ long, gg W-L- = 0.035 x 0.5 = 0.0175 Green/narrow/short, G-wwll = 0.035 x 0.5 = 0.0175 Yellow/wide/ short, ggW- ll= 0.035 x 0.5 = 0.0175Finally, as we need to obtain the numbers of the individuals with those phenotypes, we need to multiply each frequency by N, which is the total number of individuals in the F2 (N = 800).
Green/Wide/Long, G-W-L- = 0. 2325 x 800 = 186 individuals Yellow/narrow/ long, gg ww L- = 0. 2325 x 800 = 186 individuals Green/wide/ short, G-W-ll = 0. 2325 x 800 = 186 individuals Yellow/narrow/ short, gg ww ll = 0. 2325 x 800 = 186 individuals Green/narrow/ long, G-wwL- = 0.0175 x 800 = 14 individuals Yellow/wide/ long, gg W-L- = 0.0175 x 800 = 14 individuals Green/narrow/short, G-wwll = 0.0175 x 800 = 14 individuals Yellow/wide/ short, ggW- ll = 0.0175 x 800 = 14 individuals

If humans have altered the natural environment, describe the changes made by humans and their impact on the species.
Answer: The changes that humans have made are the changes to the atmosphere. That is the most significant change. The burning of fossil fuels increases the Co2 levels in the atmosphere along with other greenhouse gases such as methane. This causes the temperature to rise because the heat waves are stuck in the layer. The PH levels continue to rise in the oceans due to climate change also.
Explanation:
Why is there an increase in the number of people infected with the disease despite the increase in the number of vaccinated?
Answer:
Some people refuse to take the vaccine. a person who carries or has the virus can infect hundreds of people. Therefore the few people who don't take vaccines give it to others. Also, people with the vaccine can still get corona. Most people have stopped wearing masks once they get the vaccine so they are at high risk too.
Explanation:
Basically, people's ignorance and lack of understanding are causing this.

Which of the following is NOT an example of
a convergent boundary?
A. continental crust to continental crust collision
B. mantle to core collision
C. continental crust to oceanic crust collision
D. oceanic crust to oceanic crust collision
Mantle to core collision is NOT an example of a convergent boundary. Therefore option B is correct.
Convergent boundaries are places where tectonic plates move toward each other. When they collide, various geologic processes occur.
However, option B, "mantle to core collision," is not an example of a convergent boundary. The mantle and core are both parts of the Earth's interior, and there is no boundary between them where tectonic plates interact.
The other options (A, C, and D) involve interactions between different types of tectonic plates at convergent boundaries, such as continental crust colliding with other continental crust (A), continental crust with oceanic crust (C), and oceanic crust with oceanic crust (D).
These interactions often result in significant geological phenomena like mountain formation, subduction zones, and volcanic activity.
Therefore option B mantle to core collision is correct.

9.If you break an atom apart would it still behave like the element that makes it up? (yes/no)
Answer:
Yes.
Explanation:
The energy released in splitting just one atom is miniscule. However, when the nucleus is split under the right conditions, some stray neutrons are also released and these can then go on to split more atoms, releasing more energy and more neutrons, causing a chain reaction.
Suppose that a rabbit breeder notices two individuals in a litter with large, round noses and names this trait the clown trait. He obtains another rabbit that has a long, thin nose and names it the Pinocchio trait. After breeding the rabbits with unusual nose shapes to wildâtype individuals for several generations, he decides to cross rabbits from families with a history of the clown and Pinocchio traits. The first litter from this cross results in individuals of four phenotypes. The phenotypes are clown, Pinocchio, wildâtype, and heartâshaped noses. The pedigree illustrates the inheritance of these traits. Individuals 1 and 4 are siblings and are known to come from a true-breeding wild type line.
1. What is the most likely mode of inheritance for the clown nose?
a. -linked
b. X-linked dominant
c. X-linked recessive
d. Autosomal dominant
e. Autosomal recessive
2. What is the most likely mode of inheritance for the Pinocchio nose?
1. Sex-influence
2. X-linked dominant
3. X-linked recessive
4. Autosomal dominant

Identify the highlighted muscle.
Answer:
Brachialis
Explanation:
The Brachialis is an anterior skeletal arm muscle that extends from the medial arm to the superior area of the forearm. The brachialis fibers originate in the anterior part of the humerus and direct to the inferior part of the elbow, where they insert in the upper region of the ulna and distal radius. This muscle is an elbow flexor being used in every movement needed to approximate the anterior part of the forearm to the arm. It is a very thick and powerful muscle that acts with high speed.
The upper limb or arm is the functional unit of the human body, which is made up of 6 different muscular regions, such as the pectoral, upper arm, hand, posterior forearm, and anterior forearm.
In the given image of the upper extremity, the muscle highlighted is the brachialis.
Brachialis anticus or the Teichmann's muscle is present in the upper extremity, which helps in the flexion of the elbow. The muscle is situated in the deeper biceps brachii and makes up the floor region of the elbow pit.
The muscle originates in the anterior part of the humerus and directs the inferior of the elbow. The brachialis muscle is one of the largest flexors of the elbow, which provides the movement or flexion of the forearm at the elbow.
Therefore, the given image is of the brachialis muscle.

Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.
