Explanation:

Answer:

a. 0.03054 b. 0.000032 c. sorry I am not perfect

Explanation:

A. 0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams

B. 3.02 x [tex]10^-^5[/tex] = 0.0000302

C. 3.3 x [tex]10^-^4[/tex] mL= 300

Powers of 10 are used in scientific notation to express extremely large or extremely small quantities. The formula is "[tex]\rm a * 10^b[/tex],"

where "a" is an integer representing a value between 1 and 10 (inclusive), and "b" is an integer representing a power of 10.

To write 0.03054 grams in scientific notation, we move the decimal point three places to the right to make the number between 1 and 10. this results in:

0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams

To write [tex]3.02 * 10^-^5[/tex] in conventional notation, as indicated by the exponent, we move the decimal point five places to the left. this results in:

3.02 x [tex]10^-^5[/tex] = 0.0000302

To evaluate (3.3 x [tex]10^-^4[/tex] mL) / (1.1 x [tex]10^-^6[/tex] mL), we divide the numbers in the numerator and denominator:

[tex](3.3 * 10^-^4 \rm mL) / (1.1 * 10^-^6 \rm mL) \\= (3.3 / 1.1) * (10^-^4 / 10^-^6) \\= 3 * 10^2[/tex]

Therefore, (3.3 x [tex]10^-^4[/tex] mL) is equal to 300.

The statement which represents a scenario that most likely uses the same type of cell transport as the sodium-potassium pump is that a child's badly skinned knee heals rapidly. Thus, the correct option for this question is A.

A sodium-potassium pump may be defined as a type of pump or channel or enzyme that is significantly found in the membrane of all animal cells. It performs several functions in cell physiology. The Na⁺/K⁺-ATPase enzyme is active. It effectively moves sodium and potassium ions against large concentration gradients.

According to the context of this question, the working mechanism of the sodium-potassium pump depends on the movement of two potassium ions into the cell where potassium levels are high and the pump of three sodium ions out of the cell and into the extracellular fluid. It plays an important role in contracting the cardiac muscle, kidney function, and nerve signaling.

Therefore, a child's badly skinned knee heals rapidly is the statement which represents a scenario that most likely uses the same type of cell transport as the sodium-potassium pump. Thus, the correct option for this question is A.

Explanation:

In order to meet the basic needs of increases population, the present society has under taken a series of steps like rapid industrialization, unplanned urbanisation, deforestation, overexploitation of natural sources, etc.

The outcomes of the above human activities have contributed significantly to the degradation of environment around us.

Some important impacts of human activities on environment are outlined below:

1. Deforestation:

In order to provide timber and farm land to increased population, large number of forest trees are cut and forest area is converting to farm lands. The rate of deforestation is so faster that around 1.5 million hectare of forest cover is lost every year is India alone. The process of deforestation results in decreasing rainfall, increasing global temperature, loss of top soil, modification of climatic conditions etc.

2. Industrialization:

Although the industrial activities of man provide basic need of the society, simultaneously the same release a lot of pollutants to the environment. The pollutants in environment cause loss of raw materials, health hazards, increase in death rate, damage to crop, making environment unfit for living organisms etc.

3. Loss of ecological balance:

The excessive use, misuse and mis-management of biosphere resources results in disturbance in ecosystem or ecological imbalance.

4. Air pollution:

The anthropogenic release of various air pollutants to the environment causes a number of dreaded phenomena like green house effect, ozone layer depletion, acid rain and smog formation etc.

5. Water pollution:

Human activities in respect of disposal of sewage wastes, solid wastes, municipal wastes, agricultural and industrial wastes cause the environment unfit for day to day use. Besides, polluted water spreads or leads to different diseases.

6. Increased consumption of natural resources:

Since the starting of industrial era, the natural resources are constantly utilised for the production of one or more products for the day to day use of society.

7. Production of waste:

Rapid industrialization and unplanned urbanization release a lot of toxic waste material either in solid or liquid or gaseous state which induces a number of serious environmental hazards.

8. Extinction of Wildlife:

Since forests are natural habitats of wild life (both plants and animals) deforestation leads to the extinction of valuable wild life and loss of biodiversity.

9. Habitual destruction:

The commercial and industrial activities associated with mining, construction of dams, fishing, agriculture etc. cause habitat destruction which is a pathway to pollution.

10. Noise pollution:

The man-made noise due to mechanized automobile, industries, trains, aero planes, social functions etc. causes noise pollution which has impact on both biotic and a biotic components of environment.

11. Radiation pollution:

The radiations from radioactive substances used in nuclear reactors and nuclear weapons can have significant impact on genetic materials of body (DMA, RHA etc.)

12. Soil erosion:

The anthropogenic processes like deforestation and overgrazing induce soil erosion which causes soil moisture reduction, lowering of productivity, decline in soil fertility etc.

We feel the inside of the elbow as we lift a book. We should feel a strong cord. This cord is known as Oblique cord.

The oblique cord is a ligament which is present between the ulnar and radius bones in the forearm region near the elbow. Oblique cord takes the form of a small, flattened band, which is extending downward and lateralward, from the lateral side of the ulnar bone tuberosity at the base of the coronoid process to the radius of a little below the radial tuberosity. The fibers in this cord runs in the opposite direction to those of the Interosseous membrane of the forearm region of the hand.

The oblique cord may simply be defined as an additional tie which is between the radius and ulna of the hand which is aiding other soft tissue structures such as the annular ligament and interosseous membrane. Additionally, the oblique cord may also prevent the anterior shearing of the proximal radius under the extreme compressive loads.

According to the image,

1. The reactants of photosynthesis is carbon dioxide, water, and solar energy.

2. The products of photosynthesis is glucose and oxygen

3. The photosynthesis reaction is endothermic. For a reaction to be endothermic, energy (in this case, solar energy) must be put into the system in order for the reaction to occur. Whereas, exothermic reactions are spontaneous and don't require an initial input of energy.

4. Photosynthesis is an anabolic pathway. Carbon dioxide and water are utilized to synthesize glucose. Whereas, the process of glycolysis is catabolic because you break down glucose into 2 molecules of pyruvate.

Period is defined as cycles per second. Therefore option (A) is correct.

A period T is the time required for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the period of the wave decreases.

The unit for time period is 'seconds'. Frequency and time period are in a reciprocal relationship that can be expressed mathematically as: T = 1/f or as: f = 1/T. Orbital period is the time for something to go round (orbit) something else.

Frequency and Period are in reciprocal relationships and can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

Answer:

C

Explanation:

The other answers don't seem right, so I think this answer is probably the right one.

Answer:

Without oxygen from photosynthesis animals would not have oxygen for the four type of biomolecules which all require oxygen. Carbon hydrogen and oxygen is carbohydrates and same for lipids. Proteins would not have the oxygen for CHON which is carbon hydrogen oxygen and nitrogen. And nucleic acids which are CHONP carbon hydrogen oxygen nitrogen and phosphorus would not have oxygen. And without oxygen the animals would die and not be able to produce these biomolecules.

Answer: To grow and reproduce, all creatures require energy. Cellular respiration is utilized by many organisms (including all plants) to create ATP, which is needed for cellular energy. As a substrate, carbohydrates such as glucose are used in the respiration reaction. Plants produce their own fuel for respiration through photosynthesis, but humans consume food to do so. Plants would not be able to breathe if photosynthesis did not occur. Furthermore, carbohydrates created during photosynthesis are needed to construct plant cell components such as the cellulose cell wall.

If human red blood cells are placed in solutions of different osmolarity, then the 300 osmoles/L solution will be the isotonic solution.

An isotonic solution to the red blood cell would be a solution that has the same solute concentration as the red blood cell.

Isotonic solutions are different from hypotonic and hypertonic solutions. Hypotonic solutions would have lower solute concentrations than the red blood cell while hypertonic solutions would have higher concentrations than the red blood cells.

The red blood cells of humans have a certain amount of solute in their cell sap which has been approximate to be between 286 and 295 osmoles/L. Thus, the only solution close to being an isotonic solution to these cells would be the 300 osmoles/L solution.

More about osmolarity can be found here: https://brainly.com/question/8144230

Answer: 300 osmoles/ L solution

Explanation:

The 300 osmoles/ L solution is the solution closest to the osmolarity of a normal human red blood cell.

This means that the 300 osmoles/ L solution is the isotonic solution. If added to human red blood cells, the shape and size of the red blood cells with remain as they were, unchanged (unlike if a hypotonic/ hypertonic solution was added.)
