Two parents, both with brown eyes, have four children. One child has brown eyes, like his parents, but the other three all have blue eyes. One of the children has been learning about genetics in science class and knows that brown eyes are dominant to blue eyes in humans. The student developed the following model of a Punnett square to predict the genotypes of his parents and his siblings.
Based on his model, the student claims that only one of the four children should have blue eyes. Which of the following explanations best describes why the Punnett square does not model the traits in the student’s family? (DOK 3)
Answer:
Punnett squares are not exact answers, they are only used to predict traits.
A.
The student is forgetting that a Punnett square is used to predict the outcomes of a genetic cross. The actual results do not always match up to the predicted outcomes.

Explanation:
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
Deep sea mining has never been tried successfully, so we don't know exactly how it can be done so it is difficult to know the impact of deep sea mining.
what is deep sea mining?The process of extracting and often excavating mineral deposits from the deep seafloor is known as deep-sea mining.
The deep bottom spans around two-thirds of the total seafloor and is found at ocean depths greater than 200 meters.
Deep-sea mining has been shown to affect marine biodiversity and ecosystems, but we still lack the knowledge and resources to safeguard them.
There are considerable gaps in our understanding of the deep sea's biodiversity and ecosystems since it is still understudied and poorly understood.
This makes assessing the possible effects of deep-sea mining and putting in place necessary safeguards to protect the marine ecosystem and the three billion people whose livelihoods rely on marine and coastal biodiversity challenging.
Hence , the correct option is A.

are there exits alloted for emergency escape plan? how many?
Answer:
The correct answer is - yes, multiple exits but a minimum of 2 is a must.
Explanation:
An emergency escape plan is a documented map or plan of a building that is created for the safe evacuation in an emergency such as fire, smoke, natural disaster, or any panic situation.
In an emergency escape plan, there must be easy exits for faster and safe evacuation even in low visibility or smoke condition. Multiple exit routes are allowed to any escape plans, however, two is the minimum number of exits is compulsory.
Yes, there are exits alloted for emergency escape plans. It should be multiple in number but a minimum of 2 must be necessary.
What is an emergency escape plan?An emergency escape plan is the urgent immediate egress or escape of people away from an area that contains an imminent threat of destruction, an ongoing threat, or a hazard to lives or property.
An emergency escape plan provides a path for the people of a particular area to move away from the risky or threatened places immediately. So, emergency exits play a significant role when there is any natural disaster, fire, smoke, etc. has occurred.
Therefore, there are exits alloted for emergency escape plans. It should be multiple in number but a minimum of 2 must be mandatory.

For a quantitative trait explained by four loci in an additive fashion, if the four locus genotype AaBbCcDd corresponds to a phenotypic value of 32, and the four locus genotype AABBCCdd corresponds to a phenotypic value of 48, then what is the phenotypic value corresponding to the four locus genotype AABbcCDD?
Answer:
48
Explanation:
In genetics, additive effects represent a mode of quantitative inheritance that occurs when the combined effects of alleles (i.e., the variants of a gene that lead to differential expression of a phenotypic trait) at two or more loci are equal to the sum of their individual effects, contributing thus to the final phenotype. Therefore, the additive variance can be explained by the sum of the individual effects of identified loci/genes that have an additive effect on this quantitative trait. In this case, each gene shows an additive effect (equal to 8 for each dominant allele), thereby the phenotypic value corresponding to the genotype AABbCcDD will be equal to 48 (i.e., 16 + 8 + 8 + 16 = 48).

Why do waves move faster at higher temperatures and in a solid phase?
O There is more energy and the particles are farther apart.
O There is less energy and the particles are closer together.
O There is less energy and the particles are farther apart.
There is more energy and the particles are closer together.
Answer:
B
Explanation:I took the test if u need help follow me
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.
What is meant by intermolecular force ?Intermolecular force is defined as the force of attraction experienced between the neighboring molecules in the same state.
Here,
During higher temperature and when in a solid phase, the waves exhibit movements very faster than in other phases.
This is because, when the temperature of the system is increased, the energy of the molecules in the system will be increased to a higher level. This energy formation is in the form of kinetic energy of the molecules.
Molecules in the solid phase have a greater intermolecular force of attraction with their neighboring molecules. Therefore, the molecules in the system will be more closer to each other.
As the kinetic energy of the molecules in the system increases, the molecules will start vibrating. These vibrating molecules induces the vibration to their neighboring particles, since they are closer together.
As a result, more and more highly energetic molecules are set to vibrate, which causes the wave to move faster in the system.
Hence,
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.

When will an insect that undergoes incomplete metamorphosis develop a set of wings?
a.
after its final molt
b.
when it becomes a pupa
c.
when it breaks out of its chrysalis
d.
only insects that undergo complete metamorphosis have wings
Answer:
The answer is D not sure
Explanation:
Like those of several other insect species, the stages of growth that the nymph cricket undergoes are referred to as "instars." Crickets usually go through eight to 10 instars before reaching adulthood, which takes about two to three months. Crickets start to develop wings at about 1 month of age.
Metamorphic rocks are a bit harder to identify because they can share traits with the other rock types. Again, thinking about the formation process can help. Metamorphic rocks have been heated and squashed. This can lead the minerals in them to line up, creating ribbon-like layers called bands. These rocks are called foliated metamorphic rocks. You can see these bands in gneiss. If a metamorphic rock has fossils, you know it was formed from a sedimentary rock. Because of the heat and pressure, the fossil will be hard to recognize and out of shape.
Which of the following best describes foliated metamorphic rocks?
A
There are easily recognizable fossils.
B
The rock has ribbon-like layers of bands.
C
They have crystals like igneous rocks.
D
Different sized sediments can be see
Answer:
b
Explanation:
the fourth sentence in the passage: "This can lead the minerals in them to line up, creating ribbon-like layers called bands."
Dark and light bands may alternate due to the separation of mafic (dark) and felsic (light) minerals. Having different grain sizes in the same mineral can also result in banding. Thus, option B is correct.
What are the ribbon layer present in the rock?Under the surface of the earth, metamorphic rocks are formed. The extreme heat and pressure cause them to alter. Their layers resemble ribbons. Some of them are covered in bright crystals.
Under the earth's surface, metamorphic rocks are created as a result of the transformation brought on by extreme heat and pressure (squeezing).
These processes produce rocks that frequently have layers that resemble ribbons and may have glittering crystals on their surface that were created by minerals slowly growing over time.
Therefore, This can lead the minerals in them to line up, creating ribbon-like layers called bands
