Answer:
B
Explanation:
Fertilization is the process in which male and female gametes fuse and form a fertilized egg. The correct option is B.
What is the process of fertilization?During fertilization, sperm and egg combine to form a zygote in one of the fallopian tubes.
The zygote then travels down the fallopian tube and develops into a morula. The morula develops into a blastocyst once it reaches the uterus.
The blastocyst then burrows into the uterine lining, which is referred to as implantation.
The sperm binds to the secondary oocyte via the corona radiata, a layer of follicle cells on the outside of the oocyte.
Fertilization is divided into three stages: sperm capacitation and acrosome reaction, sperm-egg binding and fusion, and cortical reaction and oocyte activation.
In a nutshell, sperm capacitation takes place in the female genital tract and prepares sperm cells for the acrosome reaction.
Thus, the correct option is B.

What is the respiratory system?
The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system serves a variety of purposes. In addition to assisting with inhalation and exhalation, it:
Enables you to speak and smell.Raises the temperature of the air to that of your body and adds moisture to it to the proper degree of humidity.Provides your body's cells with oxygen.When you exhale, waste gases from your body, including carbon dioxide, are removed.Shields your airways from irritants and dangerous chemicals.

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.
What is the 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.

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.

If human red blood cells are placed in a 0 osmoles/L solution, a 100 osmoles/L solution, a 300 osmoles/L solution, and a 500 osmoles/L solution, then _________________ will be the isotonic solution.
OPTIONS:
0 osmoles/L solution
100 osmole/L solution
300 osmoles/L solution
500 osmoles/L solution
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.)

b. Write the following in ordinary notation: 3.02 x 10-5
c. Evaluate the following: (3.3 x 10-4mL) = (1.1 x 10-6 mL)
Answer:
a. 0.03054 b. 0.000032 c. sorry I am not perfect
Explanation:
a. In the number 0.03054 , you need to move the decimal point two places to the right to get to 3.054 (which is between 1 and 10). Since you moved the decimal point two places to the right, you must indicate it by saying that you multiplied 3.054 by 10−2 . Think about it: 3.054×10−2=0.03054 . b. Answer: 0.0000302 Step-by-step explanation: When 10 is to the power of a negative number, "move" the decimal dot left. 10⁻⁵ means to "move" the decimal 5 times to the left. 1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02). 0000003 . 02 2. Count 5 place values over. 00←0←0←0←0←3 . 02 3. Put the decimal behind the digit. 00 . 0000302 4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal. 0.0000302 <= Final answer c. sorry but I am not perfect at thisA. 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.
