Answer:
I would take the chance of growing pest resistant crops to reduce the use of pesticides. Pesticides can be expensive and are also harmful, not just harmful to the environment but also harmful for humans. If a pesticide were to be consumed, a person would be at much greater risk if they consumed a large amount rather than a little amount. It's best to use pest resistant crops to avoid this.

What is Big Bang Theory?The galactic plane and the planetary orbital plane form a roughly 60° angle as the Solar System travels through the galaxy.
As it circles around the Milky Way, the Sun appears to move up and down and in and out of the galaxy.
The Big Bang, an explosion of space, marked the beginning of our cosmos. Space expanded, the cosmos cooled, and the basic elements emerged from a very high density and temperature starting point.

1. Why is it possible for the surface of a pond to freeze even though the water underneath is fluid?
2. Sugar dissolves in water, but is not an ionic compound. What does this tell you about sugar?
3. Water is used in the cells to help transport in the chemicals necessary to survive. Since cell membranes need to be able to hold in and hold out water without dissolving, what do you suspect cell membranes are made from? Why do you think this?
4. Remember "The Wicked Witch of the West" from The Wizard of Oz? She melted when doused with water. What do you think her cell membranes were made of, and why?
5. Find out why hot water freezes more quickly than cold water, and explain it here.
6. Explain why heavy water is heaver than regular water.
Answer:
Kindly check explanation section.
Explanation:
So, let us dive straight into the solution to this particular Question or problem. We are asked to explain the phenomenon in each case.
(1). Expansion occurs at the surface of a pond water when it freezes at 0°C thus creating higher density for the (liquid) water at below the iced surface.
(2). When sugar is put in water it does not ionized but only dissolved as a molecule, therefore, sugar is a weak electrolyte.
(3). Cell membranes are made of phospholipids and proteins because phospholipids as far will not want to mix with water, also movement of molecules is done by the presence of protein.
(4). The witches cell membranes does not have phospholipids which makes it to have little adhesion force and this was the prime factor in the dissolving of the witch by water. The cell membrane contain nonfatty components.
(5). The statement is true, and this is a phenomenon refer to as the Mpemba effect that is to say when one cools down hot water it looses some of it mass(reduces the quantity of water) and this is due to evaporation. Thus, as the quantity of water reduced, freezing becomes faster.
(6). Heavy water is D2O while normal water is H2O. Where D in D20 means Deuterium which is heavier than Hydrogen atoms in heavy water.

Gestalt psychology emphasizes how perception is organized. It focuses on A. the minutia that make up a human being. B. the whole as opposed to the sum of its parts. C. the detail that goes into cognitions. D. the likelihood that actions will result in behavior.
Answer:
a
Explanation:
the minuta that make up a human being
Gestalt psychology emphasizes the whole as opposed to the sum of its parts. Therefore, the correct answer is B.
The main principle of Gestalt psychology is that perception is not simply the result of combining individual sensory elements but rather involves the organization of these elements into meaningful patterns or wholes.
The focus is on how the mind organizes sensory information and perceives the overall structure or configuration, rather than analyzing the individual components in isolation. It emphasizes the whole as opposed to the sum of its parts

What is Entomology ?Entomology is defined as the investigation of insects and how they interact with people, the environment, and other living things. Entomology is employed extensively in a wide range of fields, including evolutionary biology and medical research, in addition to studying the anatomy and physiology of insects. It aids agricultural entomologists in their research on biodiversity as well as in the protection of priceless resources from insect pests.
Forensic entomology is defined as the study of arthropods, particularly insects, connected to criminal activity and other judicial issues. An essential tool in the examination of homicide, self harm, and other violent crimes is forensic entomology. When properly gathered and examined by skilled forensic investigators, insect evidence found on a victim's corpse can provide important information.

What is the primary reason organisms
undergo cellular respiration?
to get rid of wastes
to convert food to useable energy
to supply plants with carbon dioxide
+
to create energy from the sun
The primary reason organisms undergo cellular respiration is to convert food to usable energy.
Cellular respiration is a metabolic process that occurs in the cells of living organisms and involves the breakdown of organic molecules, such as glucose, to release energy in the form of ATP. This process is essential for cells to carry out their normal functions and for organisms to maintain their life processes.
Cellular respiration involves a series of reactions that break down glucose into smaller molecules, which are then used to generate ATP. During this process, oxygen is consumed and carbon dioxide is produced as a waste product. The process of cellular respiration is an efficient way for cells to convert the energy stored in food molecules into usable energy, which is essential for cell growth, repair, and reproduction.
In contrast, photosynthesis is the process by which plants and some bacteria use energy from sunlight to convert carbon dioxide and water into glucose and oxygen. This process is essential for plants to produce their own food and to release oxygen into the atmosphere.

describe how impulse are transmitted across a synapse
A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.
What are the impulse?Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.
The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

Select a potted plant from the garden and keep it in a room for five days as shown in the diagram. After five days, you can see that most of the leaves of the plant change yellow. What could be a systematic method to ask right questions? Make a hypothesis or educated guess, conducting scientific experiment and activities about the existing facts to figure out a conclusion in accordance with the scientific learning process.
Answer:
Explanation:
To systematically investigate the yellowing of the plant's leaves, you can follow these steps:
1- Observation: Observe and note that after five days in the room, most of the plant's leaves have turned yellow.
2- Question: Ask yourself, "Why did the leaves of the potted plant turn yellow after being kept in the room for five days?"
3- Hypothesis: Make an educated guess about the possible cause of the yellowing. For example, you could hypothesize that the lack of sunlight in the room caused the leaves to turn yellow.
4- Experiment: Design an experiment to test your hypothesis. Place another potted plant in a different room with similar conditions but with sufficient sunlight.
5- Data collection and analysis: Record and compare the condition and color of the leaves in both plants after five days. If the plant with sunlight has green leaves while the one in the room still has yellow leaves, it supports your hypothesis.
6- Conclusion: Based on your observations and the results of the experiment, conclude that the lack of sunlight may be the cause of the yellowing of the plant's leaves.
By following these steps, you can systematically ask the right questions, form a hypothesis, conduct an experiment, and reach a conclusion using the scientific learning process.

Why do the leaves of a potted plant kept away from sunlight turn yellow?The yellowing of leaves in a potted plant kept away from sunlight is primarily due to a process called chlorosis which is the loss or reduction of chlorophyll in plant tissues.
When a potted plant is kept away from sunlight or receives insufficient light, the plant is unable to carry out photosynthesis. Consequently, the chlorophyll content in the leaves decreases, and they start to lose their green color.
