If the two characteristics that mendel looked at in his dihybrid cross of smooth yellow peas with wrinkled green peas had been controlled by genes that were located close together on the same chromosome, then the f2 generation __________.
If the two characteristics that Mendel looked at in his dihybrid cross of smooth yellow peas with wrinkled green peas had been controlled by genes that were located close together on the same chromosome, then the F2 generation Would have deviated from the 9:3:3:1 phenotypic ratio. The correct answer is option(d).
The F2 generation's phenotype would have differed from the expected 9:3:3:1 pattern if two genes were linked together on the same chromosome. Two genes are considered to be related if their loci are near to one another on the same chromosome. Genes that are connected recombinant more frequently than unlinked genes.
Two F1 people were crossed to produce the F2 generation (from the F1 generation). A 3:1 ratio was observed as a result of Gregor Mendel's tests across three generations (i.e. for every three purple-flower-bearing plants there would be one white-flower-bearing plant).

there are two pathways that can be activated by the coagulation process. one pathway begins when factor xii is activated. the other pathway begins when there is trauma to a blood vessel. what are these pathways?
There are two pathways that can be activated by the coagulation process. One pathway begins when factor xii is activated. the other pathway begins when there is trauma to a blood vessel. These pathways are called Extrinsic and intrinsic pathways.
Extrinsic and intrinsic pathways are two prominent pathways of apoptosis or blood coagulation.
The extrinsic pathway affects the health of a person in a certain way and also has a significant impact on decision-making.
Extrinsic pathway consists of plasma factors called FVII or FVIIa which are present around blood vessels in adventitial cells and began the process of blood clotting.
On the other hand, several plasma protein factors called IX, XI, and XII are present along with kininogen that initiates the blood coagulation process when a blood vessel gets injured.

The unknow carnivorous plant discovered in the cave is lack of chloroplast at the cellular level to survive by using carnivory.
What is Carnivorous Plant?Carnivorous plants, often known as insectivorous plants, are any plants that have evolved unique pitfalls and traps for the purpose of trapping and digesting insects and other animals. Across multiple families and orders, carnivory in plants has independently evolved roughly six times. The more than 600 species of known carnivorous plants are a tremendously diverse group with, in some cases, only their carnivorous behavior in common.
The most peculiar adaptations of any plant species to low-nutrient settings are those of carnivorous ones. These plants capture and consume numerous invertebrates, and sporadically even small frogs and animals, in order to gain some nutrition. Some people refer to carnivorous plants as being "insectivorous" since one of their most popular prey items is insects.
It is not unexpected that bogs and fens, where nutrient concentrations are low yet water and sunlight are abundant during specific seasons, are the most prevalent habitat for these plants. One bog has had up to thirteen different species of carnivorous plants (Folkerts, 1982). Through their roots, the majority of plants take up nitrogen from the soil. However, plants that feed on animals use leaves that have been particularly adapted to act as traps to capture the nitrogen from their prey.

It is possible that Paul and Emily's daughter has blue eyes because the genotype of their daughter is Bb*Bb.
Brown eyes are caused by the dominant gene B. Therefore, both parents must pass on the recessive allele for the progeny to have blue eyes. This indicates that parents with brown eyes must be heterozygous.
The couple's genotype is Bb x Bb since only this combination can result in kids with a 25% chance of carrying the bb gene, which causes blue eyes.

thoroughbred horses are among the fastest horses in the world and are used in famous racing events such as the kentucky derby. the mass of a thoroughbred is about 500 kg. if a horse with this mass is galloping with a momentum of 8,220 kgm / s what is its speed?
Knowing that momentum is the product of an object's mass by its velocity (M = m*v), and having data about two of the terms, we can calculate any of these values by clearing the equation. In this case, V = 1644m/s (This is the speed).
What is the momentum?When talking about Momentum, we are referring to the motion of an object. We can calculate it in a single object, or in a system.
The momentum (M) of a single object can be defined as the product between the object's mass (m) and its velocity (v). This is, M = m * v.
The moment of a system can be calculated by adding the moments of each of the objects. This is, Mt = M1 + M2 + M3 + M4 + M5....+Mn.
In the exposed example, we have the value of momentum (8,220 kgm / s) and the object's mass (horse's mass = 500kg). So we just need to replace the terms with the provided data and clear the equation to get the speed or velocity, v.
Knowing that,
M = momentumm = massv = velocityM = m*v
8,220 kgm/s = 500 kg * v
(8,220 kg m/s) / (500 kg)= v
16.44 m/s = v
The velocity equals v = 1644m/s.

2. What does your body do in order to help you get more oxygen when you're exercising?
3. What do you think happens to athletes (like the Denver Broncos) that train in areas with "thin" air that has less oxygen? What happens to their lungs, hearts, and red blood cells over time?
Answer:
Explanation:
One
The heart is like a functioning pump. It moves the blood around the body.
The red blood cells carry oxygen which is delivered to the vital organs of the body. Muscles need oxygen to function properly.
The lungs are like a giant sieve. They separate the oxygen and carbon dioxide.
Two
One of the things the body does is increase your heart rate while exercising. That means that the body receives more oxygen from the seive action of the lungs. In other words, your heart rate increases and red cell blood flow consequently increases.
Three
Interesting application. The heart rate will have to increase to get the same amount of oxygen as the heart rate would be at lower altitutes. There is less oxygen in the thin air in Denver Colorado than say Los Angeles California.

Genotype of F1 parent plant 2:
We conclude that the genotype of the parental plants by using the information provided by the image is homozygous dominant (plant 1) and plant 2 is homozygous recessive, it is for that reason that all offspring are heterozygous.
What is a Punnett square?The Punnett square is a diagram used in genetics in order to determine the genotypes of the offspring and also in this case to infer the genotypes of parental lines when information is missing.
The only way in which all progeny of a genetic cross is heterozygous is when the parental genotypes are homozygous recessive and homozygous dominant, thereby all offspring genotypes will be 100 percent Ww because there is one type of gamete by parent.
Therefore, with this information, we can conclude that the Punett square results can be used to determine the genotype of the parental lines, being in this case all heterozygous because parents are homozygous.

According to the theory of natural selection, those organisms which can adapt to changing conditions of the environment are able to survive and pass on their characteristics to their offspring.
If the main seed size changes and larger seeds replace them, then this would mean that larger bill sizes will be needed by the birds to survive in this environment.
