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)

Two Parents, Both With Brown Eyes, Have Four Children. One Child Has Brown Eyes, Like His Parents, But

Answers

Answer 1

Answer:

Punnett squares are not exact answers, they are only used to predict traits.

Answer 2

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.

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

Answers

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

are there exits alloted for emergency escape plan? how many?​

Answers

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.

D These organelles are both important for the use of cellular genetic information to make proteins.

Answers

Answer:

The correct answer is - с. These organelles are both important for the conversion of energy to a usable form for cells.

Explanation:

Chloroplast and mitochondria are the two organelles that are essential for the biosphere specially autotrophs like plants and heterotrophs as chloroplast is the organelle that converts light energy into chemical energy by forming sugars by the process called photosynthesis by trapping the sunlight.

This chemical energy that is stored in glucose molecule moves to the mitochondria where by the procee of the cellular respiration the chemical energy converted to the ATP, the energy form that is used by the cell for the performing its function.

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.

A. Seals can swim

B.seals are predators

C.seals have fur and blubber

D.seals are warm-blooded animals

Answers

Tbh it’s either c or d because c and d are both correct
The answer is C. My answer is because A and B are irrelevant to the question, so for that it can be eliminated. But between C and D, C makes much sense. Although D, says that seals are warm blooded and is true, however frogs (amphibians) and snakes (reptiles) they are cold blooded. They need sun in order to feel warm or the heat to adjust or accommodate their bodies temperatures, unlike panthers and seals they’re warm blooded they naturally have fur and are able to regulate their bodies temperature. Therefore D is eliminated. The correct answer is C, because seals have fur and blubber it’s much more durable, and are almost as if impenetrable for the freezing water and colder weather to pass through their fur. That is why they are able to live the coast of Antarctica.

The correct answer is C.
