Whiteflies are common pest insects found on cotton, tomato, poinsettia, and many other plants. Nymphs are translucent and mostly sessile, feeding on their host plant's phloem (sap) from the undersides of leaves. They undergo incomplete metamorphosis into winged adults. Because whitefly nymphs cannot escape predation by moving, you hypothesize that their translucent bodies make them hard to spot by predators. How could you directly test this hypothesis?

Answers

Answer 1

Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Explanation:

A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.

The hypothesis can be tested by comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Describe Hydrogen Bonding.


BEST ANSWER GETS BRAINLIEST

Answers

Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water.  This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive.  The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.

Why is it important for cells to be able to
take in nutrients and excrete (remove) waste
products?

Answers

Answer:

so that our body won't contain all the bad waste and allow all the good nutrients to help out our body.

The body of an organism utilizes the nutrient and the energy derived from the food.

The digestive system of an organism is accountable for breaking, digesting, absorbing and assimilating food.

The cells in our body perform biochemical reactions in which some of the substances are harmful or fatal to the body cells if gets stashed.

The method by which the excrement from the body is thrown out is called excretion.

So, for the appropriate functioning and for the cell to sustain discarding of wastes is required.

Individuals, as well as industry—and automobile manufacturers in particular have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere. Agree or disagree

Answers

Agree because we need to look ahead into the future. We may have a normal life with not much negative effects but the future generations to come will. Plants will die causing animals to die with them. Good will become scarce and oxygen in the atmosphere will decrease.

It is right that individuals, as well as industry—and automobile manufacturers, in particular, have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere.

Carbon dioxide is a greenhouse gas, which means that it traps heat in the atmosphere. This can lead to climate change, which is already having a number of negative effects on the planet, such as rising sea levels, more extreme weather events, and changes in plant and animal life.

Individuals can reduce their carbon dioxide emissions by making changes to their lifestyle, such as driving less, using less energy at home, and eating less meat. Industry can reduce their carbon dioxide emissions by investing in new technologies, such as renewable energy and energy efficiency.

Automobile manufacturers have a special responsibility to reduce carbon dioxide emissions, as cars are a major source of greenhouse gases. They can do this by designing more fuel-efficient cars and by using alternative fuels, such as electric and hybrid cars.

It is important for everyone to do their part to reduce carbon dioxide emissions. By working together, we can help to protect the planet for future generations.

What is the role of ATP in transport of materials

Answers

Answer:

Functions of ATP in cells

Explanation:

ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.

Answer:

The role of ATP in the transport of materials :-

To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.

Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas (N2)

Answers

Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.

Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.

The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

How does your body respond to an increase in the waste products of energy production

Answers

Answer:

Energy is delivered to the body through the foods we eat and liquids we drink. Foods contain a lot of stored chemical energy; when you eat, your body breaks down these foods into smaller components and absorbs them to use as fuel. Energy comes from the three main nutrients carbohydrates, protein, and fats, with carbohydrates being the most important energy source. In cases where carbohydrates have been depleted, the body can utilise protein and fats for energy. Your metabolism is the chemical reactions in the body’s cells that change this food into energy.

Most of the energy the body needs is for being at rest, known as the Basal Metabolism. This is the minimum amount of energy the body requires to maintain its vital functions such as breathing, circulation and organ functions. The rate at which energy is utilised for such functions is known as the Basal Metabolic Rate (BMR) and varies based on genetics, sex, age, height and weight. Your BMR drops as you get older because muscle mass decreases.

Optimal energy metabolism requires getting sufficient nutrients from our foods, otherwise our energy metabolism underperforms and we feel tired and sluggish. All foods give you energy and some foods in particular help increase your energy levels, such as bananas (excellent source of carbohydrates, potassium and vitamin B6), fatty fish like salmon or tuna (good source of protein, fatty acids and B vitamins), brown rice (source of fibre, vitamins and minerals), and eggs (source of protein). There are actually many foods that provide an abundant amount of energy, particularly those packed with carbohydrates for available energy, fibre or protein for a slow release of energy and essential vitamins, minerals and antioxidants.

Foods are metabolised at a cellular level to make ATP (Adenosine Triphosphate)

by a process known as cellular respiration. It is this chemical ATP that the cell uses for energy for many cellular processes including muscle contraction and cell division. This process requires oxygen and is called aerobic respiration.

 

            Glucose + Oxygen → Carbon dioxide + Water + Energy (as ATP)

 

Initially, large food macromolecules are broken down by enzymes into simple subunits in the process known as digestion. Proteins are broken down into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol—through the action of specific enzymes. Following this process, the smaller subunit molecules then have to enter the cells of the body. They firstly enter the cytosol (the aqueous part of the cytoplasm of a cell) where the cellular respiration process begins.

Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other

Answers

Answer:

Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.
