Answer:

D. Weight varies with location, but mass does not vary

Explanation:

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

[tex] Weight = mg [/tex]

Where;

Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.

Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).

Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.

Answer:

A) spontaneous generation

Explanation:

Spontaneous Generation theory stated that living organisms could be spontaneously generated from non-living matter. Francesco Redi conducted an experiment similar to the one Louis Pasteur would do nearly 200 years later. The 17th-century Italian developed a spontaneous generation experiment that showed that maggots do not spontaneously emerge from decaying meat.

MARK THIS ANSWER BRAINLIEST PLEASE ❤️

The theory of spontaneous generation is an experiment that tries to prove the possibilities that living organisms can be produced from non-living origins.

This experiment was first done by Francesco Redi in 1668. However, several scientists such as John Needham, Louis Pasteur, John Tyndall amongst other scientist tried to disprove the theory of spontaneous generation.

The theory was later disproved by Louis Pasteur and John Tyndall in the mid-19th century.

In a starch molecule, the energy is stored in the bonds between atoms, and the building blocks of this molecule are simple sugars.

Starch is a carbohydrate and a polysaccharide, this means this molecule is composed of dozens of glucose molecules that have formed a chain and it is used by organisms, especially plants to store energy.

In other words, starch is the result of glucose molecules forming a chain, and glucose is considered a simple sugar. Therefore, starch is made up of simple sugars.

On the other hand, the energy in starch can be found in the bonds between atoms. This implies once the bonds between atoms break energy is released, and this energy is used by organisms for multiple activities.

Answer:

Due to presence on opposite side of the globe.

Explanation:

My model support the claim that  the Northern and Southern Hemispheres  have different seasons due to present on different location on the globe. The seasons in the Northern Hemisphere are different and opposite of those in the Southern Hemisphere. Seasons occur because Earth is tilted on its axis. This tilting causes summer in one location whereas winter in other location. The Earth's tilt causes the Southern Hemisphere to lean towards the Sun during summer season of Southern Hemisphere while on the other hand, it is winter season in the Northern Hemisphere which leans away from the Sun.

Answer:

Because the earth continuously receives solar energy from the sun, it is considered a renewable resource.

Answer:

Explanation:

1.During glycolysis,four molecules of ATP are formed,and two are expended to cause the initial phosphorylation of glucose to get the process going.This gives a net gain of two molecules of ATP

For every glucose molecule that undergoes cellular respiration, the citric acid cycle is carried out twice; this is because glycolysis (the first stage of aerobic respiration) produces two pyruvate molecules per glucose molecule. During pyruvate oxidation (the second stage of aerobic respiration), each pyruvate molecule is converted into one molecule of acetyl-CoA—the input into the citric acid cycle. Therefore, for every glucose molecule, two acetyl-CoA molecules are produced. Each of the two acetyl-CoA molecules goes once through the citric acid cycle.

The citric acid cycle begins with the fusion of acetyl-CoA and oxaloacetate to form citric acid. For each acetyl-CoA molecule, the products of the citric acid cycle are two carbon dioxide molecules, three NADH molecules, one FADH2 molecule, and one GTP/ATP molecule. Therefore, for every glucose molecule (which generates two acetyl-CoA molecules), the citric acid cycle yields four carbon dioxide molecules, six NADH molecules, two FADH2 molecules, and two GTP/ATP molecules. The citric acid cycle also regenerates oxaloacetate, the molecule that starts the cycle.

While the ATP yield of the citric acid cycle is modest, the generation of coenzymes NADH and FADH2 is critical for ATP production in the final stage of cellular respiration, oxidative phosphorylation. These coenzymes act as electron carriers and donate their electrons to the electron transport chain, ultimately driving the production of most of the ATP produced by cellular respiration.

Answer:

Codons after the mutation are not exactly the same as before mutation, because one base was deleted, changing the sequence of codons.

Codons before mutation:  ATG   TGC   GAA   ACT   TTG   GCT

Only the first one (ATG) might coincide with one of the codons before mutation.

Explanation:

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the DNI or mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are a total of 64 codons. 61 codify amino acids, one of these amino acids is also the start point of protein synthesis, and the left three codons are stopping translation points.

The Sequence before mutation ATGCTGCGAAACTTTGGCTGA

Codons: ATG   CTG   CGA   AAC   TTT   GGC   TGA

The Sequence after mutation ATGTGCGAAACTTTGGCTGA

Answer:

3) passive transport

Explanation:

Passive transport is a type of cellular transport that does not require the use of energy to move substances (i.e., ions and molecules) across biological membranes. Passive transport uses concentration gradients to move substances across cell membranes, thereby transporting them from regions of high concentration to regions of low concentration. Passive transport can be divided into 1-osmosis (i.e., movement of solvents), 2-diffusion (i.e., movement of solutes), and 3-facilitated diffusion (i.e., movement of molecules with help of protein channels or carriers), and 4-filtration (i.e., movement of water by using a pressure gradient).

Answer: moves particles from on area of low concentration to an area of high concentration

Explanation: Active transport differs from passive transport because active transport

can only move particles into the cell.

does not require energy to transport particles.

moves particles from an area of low concentration to an area of high concentration.

depends on the random movements of particles to carry them across the membrane.

C. Secondary Succession

The process of an ecosystem returning to its stable form after a disaster is known as secondary succession.

This happens faster than primary succession because the soil is already formed and nutrients are more available at the beginning of the process.

Hope it helps you! ＼(^ᴥ^)／

Secondary is the type of succession that occurs when all of the usable soil has been destroyed in an ecosystem.

Succession is the process of change and development that occurs in an ecosystem over time. It refers to the gradual replacement of one community of plants and animals with another, as each community modifies the physical and biological environment in which it lives. There are two main types of succession: primary succession and secondary succession.

Primary succession occurs in an ecosystem that has no soil or vegetation, such as on newly formed volcanic islands or in areas where glaciers have retreated. During primary succession, the ecosystem must develop from scratch, with the creation of new soil and the establishment of new plant and animal communities. This process can take a significant amount of time.

Secondary succession occurs when all of the usable soil has been destroyed in an ecosystem. This type of succession can occur after a natural disaster, such as a fire or a flood, or after human activity, such as logging or farming. During secondary succession, the ecosystem must rebuild itself from scratch, with new soil being created and new plant and animal communities establishing themselves. This process can also take a significant amount of time, depending on the severity of the disturbance and the conditions of the ecosystem.
