What is gene therapy in a short answer?
Answer:
Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
Answer:
Gene therapy is a medical field that focuses on the genetic modification of cells to produce a therapeutic effect or the treatment of disease by repairing or reconstructing defective genetic material.

As sister chromatids separate, cells enter ____ and they finish separating and a nucleus reforms around each set of new chromosomes in ____ . During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.
Answer:
cell; prophase. prometaphasemetaphase. anaphase, telophase.Explanation:
Mitosis is the division of the cell and begins with a stage called prophase. As the nuclear envelope finishes dissolving, the cells enter prometaphase, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is metaphase. As sister chromatids separate, cells enter anaphase and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase. During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.

Organisms that live in similar environments, such as the ocean, often have similar adaptations. This is often due to
A. convergent evolution
B. coevolution Proton
C. gradualism
D. sexual selection
Answer:
A.
Explanation:
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time.
Organisms that live in similar environments, such as the ocean, often have similar adaptations, and this is often due to convergent evolution, which is in Option A, as convergent evolution is a process by which organisms that live in similar environments adapt.
What are coevolution and convergent evolution?Convergent evolution occurs because the same selective pressures are acting on the organisms, leading to the development of similar adaptations, such as streamlined bodies and fins, in many species of fish that live in the ocean and this is due to convergent evolution.
Hence, organisms that live in similar environments, such as the ocean, often have similar adaptations, and this is often due to convergent evolution, which is in Option A, as convergent evolution is a process by which organisms that live in similar environments adapt.

The human body needs minerals to survive. Without
minerals, the body could not function properly. The minerals
that make up rocks are the same minerals that someone
might eat in a bowl of cereal! The body needs about 80
different types of minerals to function properly. Iron enriches
the blood, salt maintains fluid balance, calcium fortifies the
bones, and fluorine strengthens the teeth. Most vital
minerals can be absorbed into the body from eating plants
and lean meats. However, many food manufacturers add
minerals to their products to make them more desirable to
consumers. Eating a balanced diet can ensure that the
proper amount of these essential minerals is ingested.
Question:
The passage tells us that "many food manufacturers add minerals to their products to make them more desirable to consumers." Do you think that this is a good idea? What are the pros and cons?
Answer:
You have to put down what you think and not what other people thing
Explanation:
You can simply answer this question yourself by doing research or just thinking if its a good idea
Eating vegetables and lean meats can help the body absorb the majority of essential nutrients. However, many food producers add minerals to their products to increase customer appeal.
What are nutrients?Chemical elements known as nutrients are present in all living things on Earth. They are essential to the survival of all living things, including humans, animals, and plants.
The breakdown of food by nutrients provides energy for living things. They are utilised in every bodily function of an organism.
The majority of vital nutrients can be more easily absorbed by the body when veggies and lean meats are consumed.
To boost consumer appeal, several food companies do, however, add minerals to their products.
Although processing has many advantages, it can also be harmful and reduce the nutritional value of food.
For instance, blanching causes vitamin and mineral leaching losses. Additionally, during processing, milling and extrusion might result in the physical removal of minerals.
Thus, these are some pros and cons of the given scenario.

The temperature equivalent to 77°F is
°C.
Use the formula to convert the temperature.
Answer:
25 degree celcius
Explanation:
formula
(given degree Fahrenheit - 32)×5÷9
(77 - 32)× 5÷9
= 25°C
Here I will show you how to convert 77 F to C so you know how hot or cold 77 degrees Fahrenheit is in Celsius. The F to C formula is (F − 32) × 5/9 = C. When we enter 77 for F in the formula, we get (77 − 32) × 5/9 = C.
so therefore the answer is 25 degrees celsius

Scientists believe Polar Bears have evolved from a group of Brown Bears that became an isolated population during a time when the Earth's climate began cooling down.What are some adaptations that make Polar Bears different from Brown Bears and what do you think caused the adaptations to occur?
Answer:
One adaptation is white fur. There was probably one white cub born to a brown bear mother, and the fur helped camouflage it for safety and later, hunting. This bear would have been more successful in hunting in the arctic, so it was more likely to reproduce and pass on the white fur genes. A second adaptation is the long claws of brown bears that are used for digging through vegetation would have shortened to be safer on ice. Polar bear paws also have little sticky bumps on their paws for gripping ice.
A third adaptation is that polar bears don't hibernate in winter. In winter, there is a lot more food available to them, so they need to stay awake. A fourth adaptation is their hair is also now water repellent, because most of their food comes from the sea. A fifth adaptation is in their digestive system. Polar bears don’t digest carbohydrates as well as brown bears, because their diet has much more fat than anything else. Polar bears hunt seals and can convert the blubber into fat for their bodies to live off of when food is scarce.
How might a wildfire influence mass wasting? By drying out (removing the water) from the regolith on a slope, wildfires decrease the likelihood of a mass wasting event. A wildfire can dry out the regolith on a slope, making it less cohesive and more likely to travel downward. Wildfires burn only at the bottom of a slope, which oversteepens the slope and induces mass wasting. The ash from the wildfires lands on the slope, adding enough mass to instigate mass wasting. Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Answer:
Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Explanation:
The plants present in a region, protect the soil from being eroded by the impact of rain or wind. This is because the roots of the plants leave the soil more aggregated, block the impact of the wind and allow water to infiltrate. This protection is increased on slopes, where the chances of erosion are greater. However, when a fire occurs and these plants are killed, the roots no longer provide protection to the soil, leaving it drier and looser. This causes the wind to break this soil apart, facilitating erosion. In addition, rainwater has difficulties in infiltrating the soil and ends up draining, taking parts of the soil with it and causing erosion.
