Answer:

No, bears are consumers

Explanation:

Both decomposers and consumers are heterotrophic organisms, i.e., they cannot produce their own food. There are four different classes of heterotrophic organisms: decomposers, herbivores, carnivores and omnivores. The decomposers are heterotrophic organisms that return nutrients to the soil from the organisms that break down. Moreover, bears are classified as omnivores (consumers) that need to kill to get their food. These animals obtain nutrients and energy from both plant and animal sources.

Bears are consumers

Answer:

disaccharides

Explanation:

they are formed by linking 2 monosaccharides through condensation

monosaccharides are simple sugars or glucose

Disaccharides are those types of carbohydrates that, when hydrolyzed by acids or enzymes, produce two molecules of monosaccharides that may or may not be identical. Thus, option A is correct.

Mono- and disaccharides, sometimes known as sugars, make up a significant portion of the carbohydrates included in food.

Disaccharides function similarly to other carbohydrates as a source of energy for the body.

When we consume foods containing disaccharides, our systems convert them into monosaccharides, or simple sugars, for absorption in the small intestine.

This condensation process is also referred to as a dehydration reaction, since a water molecule is released during this process.

Therefore, disaccharide is formed from monomeric subunits.

Answer:

The nucleus is the "brain" of the cell, the organelle responsible for producing ribosomes, as well as controlling all cell actions.

Explanation:

Answer:

A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.

sorry i am really late just what to help other people:)))

Answer:

Cellular respiration is the process responsible for converting chemical energy, and the reactants/products involved in cellular respiration are oxygen, glucose (sugar), carbon dioxide, and water. While the exact steps involved in cellular respiration may vary from species to species, all living organisms perform some type of cellular respiration. The equation for aerobic respiration shows glucose being combined with oxygen and ADP to produce carbon dioxide, water, and ATP

Answer: OSMOSIS

Explanation:

Osmosis is when solvent molecules move through a selectively permeable membrane into a region of a higher solute concentration, so that it would equalize the solute concentration on both side. (THINK: water always goes to salt, never the other way around)

Explanation:

Arrows have come to represent protection and defence from any evil that can come to you. Sustenance – Arrows were used to fight enemies and to hunt food, two important aspects of sustaining life. As a result, an arrow symbolizes maintaining and protecting life.

REAL NAME - SHRESTH DUBEY

The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.

They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).

The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.

The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

Answer:

The passive transport of a substance by its concentration gradient through a protein channel is called facilitated diffusion.

Explanation:

Facilitated diffusion is a type of passive transport through the membrane, which involves the use of integral proteins called protein channels or transport proteins, and moves substances unable to cross the membrane by simple diffusion.

An example of facilitated diffusion through protein channels is the ion channel. Ions, being electrically charged particles, cannot pass through the plasma membrane. A protein channel -which crosses the whole thickness of the membrane- constitutes a space where ions can move depending on their concentration gradient.

In facilitated diffusion, both protein channels and transport proteins do not require energy, so it is a transmembrane passive transport process.

Answer:

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic

Explanation:

Since the cell possesses a cell wall and genetic information, it has to be an animal cell.

     -this is a plant cell because of the cell wall

Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.

     -prokaryotes don't have DNA contained in a nuclear membrane

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

     - DNA contained in a nuclear membrane --> eukaryototic

     - cell wall --> plant cells, which are eukaryotic

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

      -DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too

Answer:

Statement A - cellular membrane

Statement B - eukaryote

Statement C - spore

Statement D - prokaryote

Explanation:

The cell membrane is a protective layer present around the cell and cell organelle that regulates and allows different molecules to enter and exit to regulate homeostasis.

Eukaryotes are the organism that can be unicellular or multicellular with the cells contain a nucleus in it.

Spores are reproductive cells that has a resistant layer that protects the cell from an unfavorable condition and capable to form an adult.

An organism that is unicellular and lacks the nucleus is known as a prokaryote and bacteria is an example of such organisms.

Answer:The shape of a cell greatly influences its function. Each cell has a shape that best suits its functions. For example, red blood cells are round with a large surface area on top to absorb maximum oxygen. ... Nerve cells are long and have elongated terminal branches to pass messages over long distances in our body.

Answer:

When trying to describe the nature of science, it can be useful to think of science as a culture in just the same way that we think of the cultural worlds of art and music. We need to understand and talk art or music when we enter these worlds. In the same way, we need to be able to understand and talk science.

Cockroach is you answer.

Explanation:

They do this by using a very efficient breathing system that uses air filled tubes, called trachea, to deliver oxygen directly to cells. Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing.

The tentacles provide the fish with shelter from predators.

Answer:

30C

Explanation:

One sign that a chemical reaction has taken place is the production of a gas. The more gas bubbles produced, the more reactions that the enzyme is catalyzing.

The highest number of gas bubbles are produced at 30C. The enzymes have the greatest activity in catalyzing chemical reactions at this temperature.

Therefore, this is the optimum temperature for the enzymes in this experiment.

Answer:

Homeostasis is the ability to keep a stable internal state, despite changes in the environment. All living organisms must regulate their internal environment to process energy and survive. Hope it helps
