Answer:
The correct answer would be option d.
Resources such as solar energy, wind energy, tidal energy, et cetera are renewable resources. Thus, they are inexhaustible in nature. In addition, they are a clean source of energy, that is, they do not cause pollution or environmental changes.
In contrast, fossil fuels such as petrol, diesel, et cetera are non-renewable resources, that is, they are present in limited amount in nature. They would exhaust in the near future if they are being used on the current pace.
In addition, they also cause pollution and global changes such as global warming, climate changes, et cetera.

A population of hummingbirds is composed of individuals with short or long beaks, which they use to reach nectar inside flowers. A flowering trumpet vine that produces many deep, bell-shaped flowers is introduced to the region, resulting in fewer short-beaked and more long-beaked hummingbirds. Which of the following conditions most likely caused this shift in the hummingbird population?
Hummingbird predators avoided areas where the trumpet vine grew.
Hummingbirds that compete for nectar were more successful with long beaks.
Hummingbirds with short beaks overproduced offspring with longer beaks.
Hummingbirds starved because the trumpet vine limited the food supply.
Answer: Hummingbirds that compete for nectar were more successful with long beaks.
Explanation:
Adaptation is a change that helps an organism to survive in it's environment. These changes may occur in the genetic make up, physiology, morphology and behavior.
The hummingbirds compete for nectar are of two morphological types such as short and long beaks. Both of these hummingbirds compete for the same resources. Therefore, the hummingbirds with long beaks will be able to obtain nectar from bell shaped flowers. Hence, these will be able to produce more number of offsprings and the adaptation of long beak will become prominent in subsequent generations.

Why is there controversy to the opinion that human contribution of carbon dioxide to the atmosphere is causing global warming?
choose the answers that best fit
Because the Earth goes through periodic cycles of cooling and warming.
Because the levels of carbon dioxide being released by humans has not increased since the past.
Because climate is so complex that the two cannot be definitively related.
Because the statistics are not clear about how much additional carbon dioxide input would be required to raise global temperatures.
Answer: Because the statistics are not clear about how much additional carbon dioxide input would be required to raise global temperatures.
Explanation:
Global warming can be define as the increase in temperature worldwide due to increase in abundance of greenhouse gases in the atmosphere. These gases are responsible for trapping the heat energy from sunlight.
Carbon dioxide is also a greenhouse gas which is chiefly responsible for global warming. There is a controversy that human beings are responsible for global warming as release of carbon dioxide into the atmosphere is due to burning of fossil fuels and deforestation on the large scale. But volcanic eruption and other natural factors are also responsible for such increase in abundance. Therefore, a proper statistical account for release of carbon dioxide in the environment has not been framed.

During rem sleep, your skeletal muscles are relaxed because messages from the motor cortex are blocked by the
Answer:
Brainstem
Explanation:
During REM sleep , the electrical activity of our muscles get reduced or paralysed which is primarly due to blocking of messages by the brainstem.
Trigeminal motor neurons found in the brain cell helps in moving the muscles but during REM sleep, the two neurotransmitter receptors namely GABAA and glycine are paralysed by the brain stem and hence no muscle activity could be observed during the REM sleep

Structural protein found in skin and connective tissue:
Skin and connective tissue mainly contain collagen, a structural protein, providing tensile strength. Other proteins like elastin and reticular fibers provide flexibility and support respectively. These proteins are crucial components for all tissues and body functioning.
Explanation:The structural protein found in skin and connective tissue is predominantly collagen. Collagen fibers are flexible, fibrous proteins that give connective tissue tensile strength. These fibers can be organized in various ways, such as irregularly in areas exposed to stress from all directions like the dermis of the skin.
In connective tissue, other types of protein fibers are also present such as elastic and reticular fibers. Elastic fibers, composed of elastin, can stretch and return to their original shape providing flexibility.
Reticular fibers, thin strands of collagen, form a network to support tissue and other attached organs. These proteins are important components of the body's tissues and functional chemicals.

Why did redi carry out another experiment with three jars?
Francesco Redi performed an experiment with three jars to disprove the theory of spontaneous generation by showing that maggots did not randomly appear but were born of flies' eggs.
Explanation:Francesco Redi was a 17th century Italian physician who conducted an experiment with three jars to disprove the then-prevalent theory of spontaneous generation, which claimed that living organisms could arise from non-living matter. Each jar had meat in it. The first jar was left open, the second was covered with gauze, and the third was sealed. Flies were able to lay eggs on the meat in the open jar, resulting to maggots. For the second jar, flies were attracted to the meat but were unable to reach it due to the gauze, hence no maggots were found. And for the sealed jar, there were no flies nor maggots observed. This experiment established that the maggots did not spontaneously appear but were born of the flies' eggs.

the main function of vitamin e in the body is to act as a(n) ____.'
Vitamin E serves as a potent antioxidant in the body, protecting cells from oxidative damage by scavenging free radicals. It helps maintain cellular integrity and has a role in regulating enzyme activities and neurological functions. It's found in vegetable oils, nuts, and spinach.
The main function of vitamin E in the body is to act as a biological antioxidant. Vitamin E, which is a group of compounds including tocopherols and tocotrienols, performs its antioxidant role by scavenging harmful by-products of metabolism, such as free radicals. These highly reactive molecular fragments can cause oxidative damage within the body, and vitamin E protects cells by preventing the oxidation of lipids, which is crucial for maintaining the integrity of cell membranes.
As a chain-breaking antioxidant, vitamin E interacts with free radicals to form a tocopheryl radical, which is then reduced back to its original state by another antioxidant such as vitamin C. This process not only protects the body's cells and tissues from oxidative stress but also prevents the oxidation of fats in foods, keeping them from becoming rancid. The activity of vitamin E extends to inhibiting certain enzyme activities and playing a role in neurological functions.
Sources of vitamin E include vegetable oils, nuts, and spinach. A deficiency of this vitamin can lead to issues like anemia and retinal damage, while excessive intake beyond recommended amounts may lead to toxicity.

The relationship between bacteria and legumes that results in nitrogen is best described as mutualistic.
What do you mean by mutualistic relationship?Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction.
A mutualistic relationship is when two organisms of different species "work together," each benefiting from the relationship.
Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions. While mutualism is highly complex, it can be roughly broken down into two types of relationship.
