Answer:

Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.

Explanation:

An acid is a substance that releases hydrogen ions into an aqueous solution. A base is a substance that releases hydroxide ions.

Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils.

Photosynthesis is part of the carbon cycle.

Plants absorb carbon dioxide & sunlight in the middle of the photosynthesis process and create glucose (a type of sugar).

I hope this helps,

have a wonderful day. :)

Photosynthesis is part of the carbon cycle. Therefore option A is correct.

Photosynthesis is a vital process in the carbon cycle, which is the biogeochemical cycle that describes how carbon is exchanged and recycled between the atmosphere, living organisms, oceans, and the Earth's crust.

During photosynthesis, green plants, algae, and some bacteria convert carbon dioxide (CO2) from the atmosphere into organic compounds, such as glucose, using sunlight as an energy source.

This process removes CO2 from the atmosphere, reducing greenhouse gas levels and helping to regulate the Earth's climate.

It is an essential step in maintaining the balance of carbon in the biosphere and plays a significant role in sustaining life on our planet.

Therefore option A Photosynthesis is correct.

Answer:

Biologists and other scientists use the scientific method to ask questions about the natural world. The scientific method begins with an observation, which leads the scientist to ask a question. She or he then comes up with a hypothesis, a testable explanation that addresses the question.

A hypothesis isn't necessarily right. Instead, it's a "best guess," and the scientist must test it to see if it's actually correct. Scientists test hypotheses by making predictions: if hypothesis \text XXstart text, X, end text is right, then \text YYstart text, Y, end text should be true. Then, they do experiments or make observations to see if the predictions are correct. If they are, the hypothesis is supported. If they aren't, it may be time for a new hypothesis.

How are hypotheses tested?

When possible, scientists test their hypotheses using controlled experiments. A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant. We'll look closely at controlled experiments in the next section.

In some cases, there is no good way to test a hypothesis using a controlled experiment (for practical or ethical reasons). In that case, a scientist may test a hypothesis by making predictions about patterns that should be seen in nature if the hypothesis is correct. Then, she or he can collect data to see if the pattern is actually there.

Controlled experiments

What are the key ingredients of a controlled experiment? To illustrate, let's consider a simple (even silly) example.

Suppose I decide to grow bean sprouts in my kitchen, near the window. I put bean seeds in a pot with soil, set them on the windowsill, and wait for them to sprout. However, after several weeks, I have no sprouts. Why not? Well...it turns out I forgot to water the seeds. So, I hypothesize that they didn't sprout due to lack of water.

To test my hypothesis, I do a controlled experiment. In this experiment, I set up two identical pots. Both contain ten bean seeds planted in the same type of soil, and both are placed in the same window. In fact, there is only one thing that I do differently to the two pots:

One pot of seeds gets watered every afternoon.

The other pot of seeds doesn't get any water at all.

After a week, nine out of ten seeds in the watered pot have sprouted, while none of the seeds in the dry pot have sprouted. It looks like the "seeds need water" hypothesis is probably correct!

Let's see how this simple example illustrates the parts of a controlled experiment.

24 hours and 37 minutes

Explanation:

At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.

Answer:

The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.

Transpiration helps to pull water and dissolved minerals up through the roots and stems of plants and into the leaves, which is present in the third option as the transpiration creates a negative pressure, or tension, in the leaf tissues.

Plants absorb water and minerals from the soil, and these minerals, such as nitrogen, phosphorus, and potassium, are essential for plant growth and development, the roots of plants have tiny, hair-like structures called root hairs, which increase the surface area of the root and help in the absorption of water. Water and minerals are absorbed by the roots to be transported upwards through the plant stem to the leaves, and this transport occurs in specialized vascular tissues called the xylem and the phloem.

Hence, transpiration helps to pull water and dissolved minerals up through the roots and stems of plants and into the leaves, which is present in the third option.

The initial speed is 3 m/s and final speed is 5 m/s. Change in speed is 2 m/s.

The initial speed is 3 m/s and final seed is 5 m/s. The change in speed is final speed minus initial speed.

The rate at which distance changes over time is known as average speed. The pace at which displacement changes over time is known as average velocity.

Change in speed= 5 m/s − 3 m/s

                            = 2 m/s.

Velocity = speed/ time

           = 2/ 4

          = 0.5 m/s

acceleration = velocity/ time

                    = 0.5/ 4

                   = 0.125 m/s2

Therefore, The initial speed is 3 m/s and final speed is 5 m/s. Change in speed is 2 m/s.

Neurological and perceptual speeds are generally higher in individuals with higher intelligence.

Neurological and perceptual speeds are generally found to be higher in individuals with higher intelligence. Thus, the correct option will be C.

Neurological speed can be defined as the speed or how fast the neurons react in the body, how fast a person acquires and processes the information. Neurological speed can be calculated through aptitude tests. These are the tests which are designed to predict a person's future performance and aptitude is the capacity of a person to learn.

Perceptual speed is the speed which indicates the automaticity as well as the efficiency of processing novel visual information and speed of decision-making of a person. Perceptual speed is typically assessed with the speeded tests that require the quick identification of specific targets from a set of stimuli in the body.

Neurological and perceptual speeds are generally higher in the individuals with higher intelligence.

Therefore, the correct option will be C.
