what are substrates in biology

Answer:

True

Explanation:

The correct answer is the independent variable is one that you manipulate, control, or vary to investigate its effects and the dependent variable that being tested and measured in an experiment .

The simplest way to determine which variable in your experiment is the Independent Variable (IV) and which is the Dependent Variable (DV) is to put both variables in the sentence below in the correct order. "A change in the DV is caused by the IV." It is impossible for DV to cause any change in IV."

Example: Independent and dependent variables You plan a study to see if changes in room temperature affect math test scores. The temperature of the room is your independent variable. You change the temperature of the room by making it cooler for half of the participants and warmer for the other half.

Social institutions could be used to disseminate a particular ideology depending on the society.

The question of whether social institutions such as schools should be used to disseminate a particular ideology is a complex issue with arguments on both sides.

On one side, schools should promote a specific ideology to instill shared values and beliefs that are essential for a cohesive society.

On another hand, schools should remain neutral, provide students with diverse perspectives, and encourage critical thinking to foster individuality and creativity.

Ultimately, the role of schools in disseminating an ideology depends on the values and goals of society, and the role that schools are expected to play in shaping individuals into responsible citizens.

Natural selection is a process by which certain traits within a population are favored and become more common over time, while others become less common or disappear.

It occurs because individuals with certain advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. This results in adaptation, where the population gradually becomes better suited to its environment through the accumulation of beneficial traits.

The theory of natural selection was proposed by Charles Darwin, a British naturalist, in his 1859 book "On the Origin of Species." Darwin observed that individuals within a population show variation in traits and that some of these traits provide benefits in surviving and reproducing in their environment.

Answer:

Recycling is the process of converting waste materials into new materials and objects.It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions.

When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. When energy demand decreases, fewer fossil fuels are burned and less GHGs are emitted into the atmosphere, which can help lessen the impacts of climate change and decrease air pollution.

Answer:

The process of converting waste materials into reusable material is called recycling.When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. ... This means less need for hazardous waste landfills and incinerators, as well as a decrease in energy used for those systems, which leads to less pollution

4. aldehyde are organic compounds in which a carbon atom shares a double bond with an oxygen atom, a single bond with a hydrogen atom, and a single bond with another atom or group of atoms

aldehydes are named as derivatives of the longest carbon chain containing the aldehyde group. Thus, HCHO is named as a derivative of methane, and CH3CH2CH2CHO is named as a derivative of butane. The name is formed by changing the suffix -e of the parent alkane to -al, so that HCHO is named methanal.

Explanation: true

Answer:

Unisexual and bisexual organisms are differentiated based on the reproductive systems they posses. Unisexual organisms have separate sexes male or female. Male and female reproductive systems are present in different individuals hence unisexual organisms produce male or female gametes but never both. Bisexual organisms have both male and female reproductive systems within the same individual. Hence, they are capable of producing both types of gametes. Some flowers are unisexual, and they possess only pistils or stamens. Some flowers are bisexual, and they possess both stamens and pistils together. This is the difference between unisexual and bisexual organisms.

Another important chemical reaction in daily life is the process of cellular respiration, where glucose (a sugar) reacts with oxygen to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate).

Cellular respiration is the chemical reaction that occurs within cells to convert glucose and oxygen into carbon dioxide, water, and energy in the form of adenosine triphosphate (ATP). This reaction provides the energy necessary for various cellular activities, including growth, repair, and movement.

Cellular respiration consists of several interconnected reactions, including glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain.

These reactions take place in the mitochondria of cells and involve the breakdown of glucose molecules into smaller components, ultimately releasing energy.

Without cellular respiration, organisms would not be able to generate the energy needed to survive and carry out essential functions. This process is fundamental to all living organisms, from microorganisms to complex multicellular organisms like humans.

Understanding cellular respiration and its underlying chemical reactions has significant implications in fields such as medicine, biochemistry, and physiology.

Overall, chemical reactions like cellular respiration play a crucial role in sustaining life by providing the necessary energy and molecules for various biological processes.

The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

Clumped distribution

Explanation:

A group of organisms of one species that interbreed and live in the same place at the same time. Clumped distribution is the most common type of dispersion found in nature. In clumped distribution, the distance between neighboring individuals is minimized.

The population density would be 2 ants/square inch

Population density is defined as the population size of a species of organism per unit area of the habitat occupied.

In this case, the population size of ants in the ant farm is 100 while the dimension of the ant farm is 10 inches by 5 inches.

Area of the ant farm = Length x breadth

                                   = 10 x 5

                                   = 50 square inch

Population density of ant = population size/area

                                           = 100/50

                                           = 2 ants/square inch

Sylvia can use statement A correctly in her report: "Global winds pull surface ocean water into the major ocean currents observed today."

This statement accurately describes one of the primary causes of ocean currents - the force of global winds on the surface of the ocean, which creates areas of high and low pressure and drives the movement of water.

Statement B is incorrect because global winds do not cause surface ocean currents to extend deeper beneath the surface of the water; rather, ocean currents are typically driven by the wind and waves on the surface layer of the ocean.

Statement C is also incorrect because while changes in Earth's climate can have an impact on ocean currents over long periods of time, they are not the primary cause of surface ocean currents.

Statement D is incorrect because ocean currents can exist in all parts of the ocean, not just along coastlines.
