Answers

E.Coli belongs to the eubacteria kingdom. E. Coli also belongs to the bacteria domain, the proteobacteria, and the coli species.

The well-known bacterium Escherichia coli (also known as E. coli) is a member of the phylum Eubacteria. Therefore, the correct option is D.

It is found mostly in the intestines of warm-blooded animals, including humans, and is important for digestion and vitamin synthesis. While most E. coli strains are not harmful, some can result in infections and diseases that are spread through food.

E. coli is a common organism that is also easy to grow in laboratories, making it a valuable model organism for scientific study. Its genome has been studied significantly, advancing genetic engineering, biotechnology, and medical research. Understanding the genetic structure and cellular processes of E. coli has shed light on the larger bacterial community, advancing both scientific knowledge and public health initiatives.

Therefore, the correct option is D.

Answers

Answer:c

Explanation:

Bc

A biome is a major community of plants and animals living in a specific geographic area and adapted to specific climate conditions. There are five major types of biomes: grassland, forest, desert, aquatic and tundra.

These major biomes can be divided into different categories (e.g., temperate grasslands).

The grassland is a biome that has grasses as the dominant vegetation.

The temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

In these regions (temperate grasslands) rainfall is insufficient to support trees.

The temperate grasslands have four well-defined seasons. i.e., spring, summer, fall (autumn), and winter.

Some examples of temperate grasslands include Argentine pampas, Euro Asian steppes and North American prairies.

In conclusion, the temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

The ultimate source of energy received by digesting orange is the light energy that originates from the sun provides the energy to grow the oranges, which contain macromolecules. Thus, the correct option is C.

What is the ultimate source of energy?

The ultimate source of energy of the solar system is the Sun. It is the primary source of energy for the Earth. The sun is called the ultimate source of energy because it is the source of almost all energies of the earth.

With the help of solar energy, all the green plants (producers) produce food by the process of photosynthesis. In turn, animals eat plants and use the chemical energy for all the activities such as cellular activities.

Which of the following statements is true?
A.
Chemical reactions can only absorb thermal energy.
B.
Chemical reactions can neither absorb thermal energy nor release thermal energy.
C.
Chemical reactions can either absorb thermal energy or release thermal energy.
D.
Chemical reactions can only release thermal energy.

Answers

Answer: C. Chemical reaction absorb or release thermal (and sometimes other) energy

Explanation:

Chemical reactions can result in products with more or less chemical energy than the precursors. When products have less chemical energy, the excess is converted to heat (exothermic reaction)

When the products have more chemical energy, heat must be added to make up the difference (Endothermic reaction)

Fireworks are examples of exothermic reactions where the excess is released as thermal, mechanical, and radiant energy. A lit match releases thermal and radiant energy.

Respiration is also an exothermic reaction

C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy

Respiration is the reverse of photosynthesis, an endothermic process. The overall photosynthetic reaction is 6CO2 + 6H2O + energy  —> 6C6H12O6 + 6O2

In this case radiant energy drives the reaction.

The reaction 2H2O —> 2H2 + O2 is an endothermic reaction driven by electrical energy.

Many reactions are reversible and if one is endothermic, the reverse is exothermic e.g. 2H2 + O2 —> 2H2O +energy is the reverse of electrolysis of water, or respiration vs photosynthesis.

Answers

Answer:

The speed of the frog is 1m per second the velocity is he can turn and jump in a different direction in 1 second the distance is 1m and there is no displacement.

( this was not my answer but it’s right. I saw it in the comments)

Explanation:

The speed of the frog is understood to be 1m/sec.and the velocity is that through which a frog can turn and jump in a different direction in 1 sec the distance is 1 m. This returning back to the original position represents no displacement.

What is Displacement?

Displacement may be defined as the rate of change in the position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position.

Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s).

Speed may be defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. It is a scalar quantity as it has only direction and no magnitude.

How many ATP are produced by the ETC?

A) 2
B) 4
C) 12
D) 32

Answers

Answer:

The electron transport chain or ETC for short has 34 ATP (Adenosine Triphosphate or the energy carrying molecule) Which has the molecular formula C10H12N5O13P3. So I would go with D because this is closest.

This is because one molecule of glucose in a Eukaryotic cell generates around 30 to 32 ATP.

Explanation:

The 34 ATP produced by ETC(Electron transport chain) or the electron transport stage produces the most ATP(energy carrying molecule) out of any stage in aerobic respiration/ cellular respiration cycle. While the krebs cycle, and Glycolysis produce 2 ATP each. Making the rest of the stages 30 ATP total.

Explanation:

Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.

Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.
