Why is it difficult to know the impacts of deep sea mining?
O It has never been tried successfully, so we don't know exactly how it can be done.
Olt is only done in environmentally sensitive areas, where the organisms are being harmed in many ways already, and it is difficult to know the effects of mining.
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
O Most countries have laws against it, so the impacts have not been tested.

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
These organelles are both important for the uptake of nutrients from the cell's exterior.
B
These organelles are both important in the regulated transport of molecules within cells.
с
These organelles are both important for the conversion of energy to a usable form for cells.
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.

Which statement describes how heat flows from the coffee to the part of the spoon in the coffee?

Heat flows from the coffee to the spoon through radiation.
Heat flows from the coffee to the spoon through convection.
Heat flows from the coffee to the spoon through conduction.
Heat flows from the coffee to the spoon through radiation, convection, and conduction.

Answers

Answer:

C. Heat flows from the coffee to the spoon through conduction.

The heat movement known to move from one area to elsewhere has been called heat transfer. Thermal conduction allows the coffee's heat to reach the spoon. Thus, option C is correct.

What is thermal conduction?

A type of heat transfer called thermal conduction occurs when heat flows from one spot to some other place due to the disparity in temperatures between the bodies.

When a body is subjected to thermal conduction, heat energy is dissipated from the body towards the colder or less heated objects. Because the spoon and coffee are at different temperatures, the heat from the coffee is passed to the spoon through conduction.

Therefore, thermal conduction is the process through which the coffee heats the spoon in the cup.

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?

Answers

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).

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.

A limiting factor is an environmental factor that increases the growth of population-This statement is false.

Limiting factor:

In biology, the term restricting component is characterized as a natural element or variable that has the ability to limit the development, overflow, or appropriation of a populace in an environment. These elements are available in restricted supply. Subsequently, creatures will generally vie for their restricted accessibility in the environment.

Thus, Limiting factor does not increase the growth of the population.

The captain had known the storm was cominghe had watched the weather reports for the past several days of the journeybut he started to question his decision as the waves got more powerful. One wave slapped the vessel and knocked him to the deck; when he stood up on unsteady feet, he grabbed the wheel with both hands. Though he had been a fishing boat captain for years and knew that the sea was the safest place for a vessel in a storm, these moments always terrified him. He had spent most of his life on the sea; he knew the habits and nuances of the water like it was his closest friend. The calmness that he felt when the water was placid wasnt like any stillness that he experienced on land. And though he didnt like the choppy waves when he could barely stay upright, he knew that these moments were necessary too. It was like lifein order to get to the peace, he had to weather the storm. His wife, Marla, didnt understand his obsession with the water, why he spent months of the year navigating a boat full of crab fishermen to isolated spots of the ocean hundreds of miles from shore. She couldnt grasp why he didnt get the same satisfaction from life behind a deskthe stable job in an office downtown that Marla wanted him to have. He had tried things her way, but that had only lasted a couple years; after a while, she could tell that he was miserable, and she gave him her permission to do what he loved. He gave his job two weeks notice and was back on the sea right away. He knew he missed things while he was away on these fishing boats: he listened to his wifes voice over an unreliable cell phone connection. Hed had to watch his daughter Ky speak her first words on a video that chirped into his phone. And though hed been there for her first steps, hed missed her first day of preschool, and there would inevitably be other milestones that he would miss. He stared into the blackness of the storm and knew that the fishermen below deck were relying on him to get them safely back to their familieshe knew this because he was aware of how his own family relied on him. He knew that he had to stay focused, even when he wanted to think about what his wife was doing now. He would see her in a weekand hed be able to take his daughter to school again. Hed be able to go to the grocery store and the park and do all the everyday things that he missed while at sea. He touched the picture of his family that was inside his raincoat as the next wave approached. He imagined their voices telling him that they were proud of him, and it filled him with a strength that he hadnt felt at other times during this journey. In the morning, the storm would die down, and he would enjoy the quiet. In the morning, he would call his daughter and tell her about the big storm and hear the wonder in her voice as he described the size of each wave. But for now, he was a man on a mission; he took a deep breath and held onto the steering wheel with every bit of his strength. Lets go, he thought as the biggest wave of all crashed into the boat.Question 1Part AIn the story "Life on the Sea," how does the captain mostly feel when he is on the sea?proudguiltyconfidentmiserableQuestion 2Part BWhich excerpts from the story best support the answer in Part A?Select the two correct answers."He gave his job two weeks notice and was back on the sea right away.""The calmness that he felt when the water was placid wasnt like any stillness that he experienced on land.""The storm roiled on the horizon as rough waves rocked the helm of the boat.""He had spent most of his life on the sea; he knew the habits and nuances of the water like it was his closest friend."
