Explanation:

The organelles carry genetic material from inside the nucleus to the chloroplasts for reproduction.

The correct option is D.

It's also crucial to remember that eukaryotes, being one of the three main cell divisions, are the only ones to have organelles. Prokaryotes, which include the other two major divisions of bacteria and archaea, lack membrane-bound organelles.

Like an organ in the body, an organelle is a subatomic structure that performs one or more particular functions for the cell. Some of the more important cell organelles are the nucleus, which stores genetic material, the mitochondria, which provide energy stored, and the golgi apparatus, which assemble proteins.

Answer: The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

During sexual reproduction, several alleles from both parent cells converge.

Whoever possesses a more dominant or recessive gene at the time the daughter cell is being formed will have an impact on the genetic material.

Due to the genetic and phenotypic diversity produced by sexual reproduction, people can choose partners based on whom best exhibits these traits.

Due to the options available to sexually reproducing animals, individuals compete with one another and are typically only able to pass on their genes to offspring who exhibit the desirable qualities.  

Therefore, during sexual reproduction, genetic material affected due to alleles transfer between parents.

Answer: plants take in carbon dioxide and release O2.During the day when photosynthesis occurs, the oxygen released from the process is utilized for respiration.

Answer:

grasshoppers would increase in population.

Answer: The most likely decrease in the population of the toad in the ecosystem is an increase in temperature in the ecosystem

Explanation: What is population?

Population refers to total number of Organisms or species of Organisms that is successfully interacting with each other and living together in a particular geographical area at a specific time.

Therefore, The most likely decrease in the population of the toad in the ecosystem is an increase in temperature in the ecosystem.

Answer:

Non-N-fixing plants usually benefit from reduced competition in mixed stands compared to pure stands and attain higher biomass and N content per plant

Answer:

Explanation:In the Atlantic and Northeast Pacific, we use the term "hurricane" to describe severe storms with high-velocity winds that rotate around a central, low-pressure core. The same type of disturbance in the Northwest Pacific is called a “typhoon” and “cyclones” occur in the South Pacific and Indian Ocean.

In order for a hurricane to form, two things must be present: a weather disturbance, such as a thunderstorm, that pulls in warm surface air from all directions and water at the ocean’s surface that is at least 80° Fahrenheit (27° Celsius). Because it is the interaction of warm air and warm seawater that spawns these storms, they form over tropical oceans between about 5 and 20 degrees of latitude. At these latitudes, seawater is hot enough to give the storms strength and the rotation of the Earth makes them spin.

Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. This humid air is then dragged aloft when converging winds collide and turn upwards. At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, causing it to rise as well. As the air far above the sea rushes upward, even more warm moist air spirals in from along the surface to replace it.

As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.

Eventually, hurricanes turn away from the tropics and into mid-latitudes. Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart.

Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms.

Answer:

The surface process that powers the formation of hurricanes is winds, caused by fast rotation of the Earth.The formation of hurricanes requires a combination of different factors, including warm ocean waters, moisture, and atmospheric instability. However, the primary driver of hurricane formation is the Coriolis effect caused by the fast rotation of the Earth.As the Earth spins, it causes the air and water to appear to curve as they move across the surface, which generates areas of high and low pressure. These pressure differences then create winds that move in circular patterns, which are the basis of hurricanes.So, winds, caused by fast rotation of the Earth powers the formation of hurricanes.

Explanation:

Genetically engineered foods are inherently unstable. Each genetic insertion creates the added possibility that formerly nontoxic elements in the food could become toxic.

Genetic engineering can also alter the nutritional value of food.

Another hidden risk of GE foods is that they could make disease-causing bacteria resistant to current antibiotics, resulting in a significant increase in the spread of infections and diseases in the human population. 

Answer:

Many people believe that GMOs are bad for their health – even poisonous – and that they damage the environment.

Explanation:

Moreover, most GM crops are either bred to withstand chemical pesticides or developed to generate insecticides themselves. When herbicides are applied on resistant crops, the weeds acquire resistance over time, necessitating the use of even more chemicals. Crops genetically modified to generate pesticides, on the other hand, create poisons that are toxic not just to pests but also to other insects such as butterflies, moths, and insect pollinators.

The orientation of the North Pole remains relatively fixed throughout the year. It does not change its position or direction.

The North Pole always points in the same direction in the northern sky, which is towards the North Star or Polaris.

However, the tilt of the Earth's axis in relation to its orbit around the Sun causes the amount of sunlight received by different parts of the Earth to vary throughout the year.

Answer:

d

Explanation:

The answer would be d because limitation of models is basically about non realistic part of models that separate them from real life which is what d is saying.

The branch of science which deals with chemicals and bonds is called chemistry.

The correct option is D.

Whenever a scientist gave the theory, he has to prove it experimentally and prove its physical existence to the world.

He can use various ways to prove his theory. One of the several ways of them is model making.

In the model, he tries to convey all the points which he mentioned in his theory but in the actual case the real event and the observation found in the experiment are different and no model can give you the exact 100% result without any error.

Hence, the correct answer is D that is Models usually do not have exactly the same features as the objects or events that they represent.
