Answer:

Difference:Bacteria cells are very different from animal, plant or fungal cells. They don't have organelles such as nuclei, mitochondria or chloroplasts. Although they do have ribosomes and a cell wall, these are both different in structure to the ribosomes and cell walls in the cells above.

Similar:Plant cells and bacteria alike have cell walls, strong flexible layers surrounding their cell membranes that help to counteract osmotic pressure so the cell does not burst as water diffuses into it.

As the skateboarder moves, several energy transformations take place within their body. Some of the energy transformations include:

1. Chemical energy to kinetic energy: When the skateboarder pushes off the ground, the energy stored in the chemical bonds of their muscles is converted into kinetic energy, which is responsible for their motion.

2. Kinetic energy to gravitational potential energy: As the skateboarder moves up a ramp, their kinetic energy is converted into gravitational potential energy.

3. Gravitational potential energy to kinetic energy: When the skateboarder moves down the ramp, the gravitational potential energy is converted back into kinetic energy.

4. Kinetic energy to thermal energy: As the skateboarder moves, they also experience frictional forces which convert some of their kinetic energy into thermal energy.

5. Chemical energy to thermal energy: The continuous movement of the skateboarder requires the energy stored in their muscles to be converted into thermal energy, which is released as heat.

I hope that the assistance I provided was helpful.

The motion of the skateboarder is powered by energy transformations that occur within their body. As the skateboarder moves, their body converts stored chemical energy (from food) into kinetic energy, which is the energy of motion. This conversion happens through a series of complex biochemical processes that occur within the skateboarder's muscles.

When the skateboarder pushes off the ground, their leg muscles contract, converting chemical energy stored in the form of ATP (adenosine triphosphate) into kinetic energy as the legs move and the skateboarder accelerates. As the skateboarder continues to move, the muscles in their body work together to maintain balance and control, converting chemical energy into kinetic energy and potential energy as the skateboarder jumps, turns, and performs tricks.

Additionally, the skateboarder's body also experiences other forms of energy transformation during this process. For example, as the skateboarder moves, their body generates heat through metabolic processes, which is a form of thermal energy. The skateboarder also loses energy through friction with the ground and air resistance, which is converted into heat and sound energy.

In summary, the motion of the skateboarder is powered by a series of complex energy transformations that occur within their body. These transformations involve the conversion of stored chemical energy into kinetic and potential energy, as well as the generation of heat and sound energy through friction and air resistance.

Answer:

concentric

Explanation:

Eccentric contractions are lengthening movements of your muscles. During this muscle movement, your muscle fibers are stretched under tension from a force greater than the muscle generates. Unlike a concentric contraction, eccentric movements do not pull a joint in the direction of a muscle contraction.

Answer:

Eccentric contractions have recently shown to be caused greater low- frequency fatigue than concentric. This is because size of fall in the force from eccentric contractions carry out on fresh muscle is signifgantly larger. Explanation:

Carbon dioxide is an example of an inorganic molecule.

The biosphere is the part of the Earth's surface and atmosphere where living organisms exist. It includes all the biotic (living) components, such as plants, animals, and microorganisms, as well as the abiotic (non-living) components, such as water, air, and soil.

Inorganic matter refers to non-living substances that do not contain carbon-hydrogen bonds. Carbon dioxide (CO2) is an example of inorganic matter because it does not contain carbon-hydrogen bonds and is not produced by living organisms.

Instead, it is a naturally occurring gas that is part of the Earth's atmosphere and is released through natural processes such as respiration, volcanic activity, and the burning of fossil fuels.

Proteins, carbohydrates, and sugars are examples of organic matter because they contain carbon-hydrogen bonds and are produced by living organisms through biological processes such as photosynthesis and cellular respiration.

Enzymes are biomolecules in the form of proteins that function as catalysts in an organic chemical reaction. Enzymes function as biocatalysts of a chemical reaction. The energy required by enzymes in chemical reactions is very small so that it functions to lower the activation energy. Enzymes are chemical compounds or biomolecules in the form of proteins that function to speed up metabolic reaction processes in the body, including in the digestive system. Mainly, the body produces digestive enzymes to help the process of breaking down nutrients in food so that they are more easily absorbed by the digestive system. Enzymes play an important role in cell metabolism processes. This enzyme will later act as a biocatalyst in the process of cell metabolism, meaning that it is an organic compound that accelerates chemical reactions. So, it can be said that enzymes can regulate the speed of chemical reactions that take place in cells.

Ecological succession is the development of species after a disaster that destroys an ecosystem. Since ecological succession increases the number of species living in an area, it also increases biodiversity. For example, areas that have been through heavy mining are usually stripped to barren rock..

Option c is Correct. With the exception of single-stranded genomes, cells of this sort would most likely contain all of the following.

When dividing cells of a certain type are examined under a microscope, the student discovers that each daughter cell has half as many chromosomes as the parent cell. Chemicals released into the PCM by intestinal epithelial cells stimulated the transcription of LEE genes. A cell's nucleus is a tiny, compact substance with a sphere shape.

It is frequently referred to as the "control center" since it manages all cellular functions, including cell division and heredity.

Answer: i think it an antigen and antibody reaction or a stimulus and a response

As blood glucose levels increase, hormones are released to return glucose levels to normal. This is an example of an antigen and antibody reaction.

When blood sugar levels drop, glucagon instructs the liver to convert the glycogen back to glucose, causing blood sugar levels to return to normal. Insulin also supports healing after an injury by delivering amino acids to the muscles.

After people eat, blood sugar concentrations increase. The pancreas releases insulin automatically to move glucose from the blood to the cells. As more and more cells receive glucose, blood sugar levels return to normal. The liver and muscles store excess glucose as glycogen.

Answer: Natural resources are an extremely important part of human existence on Earth.

Explanation

Resources such as air, water, and food are vital for the survival of human beings on Earth. Without these resources, humans and other living organisms will not be able to sustain and fulfill their basic needs.

Natural resources serve as the foundation for economic activities. It provides us with minerals and fossils which help us to gather the necessary pieces of equipment for completing our basic needs.

Natural resources particularly forests and oceans play a significant role in regulating the Earth's climate. It eliminates the impact of greenhouse gases to some extent.

One first learns which trait is dominant during the study of genetics, typically in high school biology or a similar course.

Genetics is the study of how traits are passed down from one generation to the next. Inherited traits can be either dominant or recessive. A dominant trait is expressed when a person has only one copy of the gene for that trait, while a recessive trait is only expressed when a person has two copies of the gene.

The concept of dominant and recessive traits is usually introduced in high school biology or a similar course. Students learn about Gregor Mendel, who is considered the father of genetics, and his experiments with pea plants. They also learn about Punnett squares and how to predict the likelihood of certain traits being expressed in offspring. Through this study, students learn about dominant and recessive traits and how they are inherited.
