Answer:

D all multI-celled heterotrophs

Explanation:

All living with organisms have been classified into kingdoms. One notable kingdom is Kingdom ANIMALIA. Members of kingdom Animalia are characterised by their HETEROTROPHIC nature i.e. they depend on other organisms for energy source.

Animals are all multicellular i.e. more than one cell and eukaryotic (membrane-bound nucleus). They are heterotrophs, which obtain their food either by saprophytism, predation, etc. Hence, according to this question, all members of the taxonomic group Animalia are multI-celled heterotrophs.

Answer:

Explanation:

An autotroph or primary producer is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). Autotrophs do not need a living source of carbon or energy and are the producers in a food chain, such as plants on land or algae in water (in contrast to heterotrophs as consumers of autotrophs or other heterotrophs). Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and as stored chemical fuel. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide. hope this helps :D

Answer:

They frequently flip-flop from one side of the membrane to the other.

According to the fluid mosaic model of cell membranes, phospholipids frequently flip-flop from one side of the membrane to the other.

The fluid mosaic model may be defined as the model of the plasma membrane that consists of two-layer of lipids and proteins molecules are embedded among the lipid bilayer.

Phospholipids have a hydrophobic tail which is found in the interior of the membrane, while a hydrophilic head is found on the outer side of the membrane.

These molecules frequently flip-flop from one side of the membrane to the other with the help of flippase, floppase, and scramblase.

Therefore, it is well described above.

The process of photosynthesis directly involves the cycling of matter as it converts the radiation energy from the sun to stored chemical energy.

Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own in the form of glucose food with the help of carbon dioxide and water in the presence of sunlight.

The complete reaction of photosynthesis is as follows:

Apart from photosynthesis, the mechanism of cellular respiration directly involves the cycling of matter.

This is because the reactants of cellular respiration are the products of photosynthesis and the reactants of photosynthesis are the product of cellular respiration.

The process of cellular respiration involves the derivation of energy from complex food molecules in the presence of oxygen.

Therefore, the process of photosynthesis directly involves the cycling of matter as it converts the radiation energy from the sun to stored chemical energy.

Answer:

Cellular Respiration.

Explanation:

We breathe out carbon dioxide back into the air which contributes to the carbon cycle.

Hope this helps! :)

The human body returns carbon to the atmosphere in the carbon cycle by cellular respiration, which is present in the second option because the carbon dioxide is released from the human body from various processes.

The cellular respiration that is carried out by animals and plants releases the carbon dioxide as a biproduct after consuming the oxygen and glucose, and when the carbon dioxide is released into the atmosphere, it is used by the photosynthetic process of the plants. The producer relies on cellular respiration because they use carbon dioxide for photosynthetic reactions, and the carbon cycle continues.

Hence, the human body returns carbon to the atmosphere in the carbon cycle by cellular respiration, which is present in the second option because the carbon dioxide is released from the human body from various processes.

Answer:

Body sensors rely on identification and quantification of internal or external stimuli like pressure, heat, texture, vibration, and tensile or compressive deformations.

Answer:

Baroreceptors sense blood pressure and then send signals to the heart, the arterioles, the veins, and the kidneys that cause them to make changes that lower or increase blood pressure.

Explanation:

There are sensors in the walls of the arteries and heart that sense blood pressure. These sensors are called baroreceptors.

Answer:

Yes, shrubs are affected.

Explanation:

The development of a pine and then a hardwood forest affected populations of shrubs because pine and hardwood trees are higher in length than shrubs so the shrubs did not gain sunlight and also all the nutrients present in the soil is extracted by the pine and hardwood trees. The shrubs present below the pine and hardwood trees slowly removes from that environment due to unavailability of sunlight and nutrients.

Answer:

The percent error between 1.34 and 1.25 is 6.716%

Solution: Given: Accepted Value = 1.34 , Observed Value = 1.25

Percent Error = | (Observed Value − Accepted Value) / Accepted Value | × 100  

Substitute values into the formula and solve:

Percent Error = | (1.25 − 1.34) / 1.34 | × 100  

= | (-0.09000000000000008) / 1.34 | × 100  

= | -0.067 | × 100  

= 6.716% (three decimal places)

Percent Error = 6.716%

Answer:

yes it's linear

Explanation:

Answer:

Water is a polar molecule and also acts as a polar solvent. When a chemical species is said to be "polar," this means that the positive and negative electrical charges are unevenly distributed. The positive charge comes from the atomic nucleus, while the electrons supply the negative charge. It's the movement of electrons that determines polarity. Here's how it works for water

Explanation:

The cohesive properties of water are given to it due to - b. Water’s polarity makes it attracted to other charged molecules.

Cohesion property is the property that is the attraction of different molecules of the same kind. Water is highly cohesive as Its molecules show strong attraction forces.

Thus, the correct answer is -  b. Water’s polarity makes it attracted to other charged molecules.

Explanation:

Answer: The molecules on the exterior of the cell will move inwards due to the difference in concentration

Explanation:

This happens because of Endosmosis, where the water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. Endosmosis is when the cell swells up due to a higher concentration in the exterior of the cell and a lower concentration in the interior of the cell.

Therefore, the water molecules move inside the cell until the concentrations of the exterior and the interior of the cell is balanced

Going by the diagrammatic illustration, the molecules would move into the cell until an equilibrium is reached.

Diffusion generally involves the movement of molecules from the region of higher concentration of a molecule to the region of lower concentration of the same molecule. The net movement will continue until both sides have equal concentrations of the molecule.

Looking at the diagram, there are more of the molecule outside the cell than inside of it. Thus, the molecules will keep moving inside the cell until both the outside and inside have the same concentration.
