Healthy top soil is needed to grow crops, which in turn some of it becomes food. Erosion is the process in which top soil is carried away by the wind or rain water (depositing it into nearby lakes or streams). Without this top soil, farming becomes more difficult and crop yields likely decrease. In some cases, no crops can be grown at all. An extreme example of soil erosion, specifically wind-driven soil erosion, is the 1930s dust bowl during the Great Depression. This occurred due to over-farming and it led to massive dust storms. In turn, it caused many farmers to leave the area.
How do vaccines help your body fight disease? Choose ALL the correct answers from the options below.
Question 1 options:
Memory B cells remember the pathogen and can produce more antibodies quickly.

vaccines have antigens of particular disease causing pathogen which are injected in our body and our body produces antibodies against them.by antigen antibody reaction they destroy the antigen which are cause of diseases and antigen are stored in memory T cells and macrophages.
You had assignment that is over due but you need extra time what is a good excuse to tell your teacher why you need extra time work on the assignment
i suggest saying you've been ill, or have had personal/family issues going on. if you say the second option, it is a bit invasive for the teacher to ask what so they shouldn't, but have something ready just in case. both of these have gotten me extensions before. :)
Please and thank you!

What are the roles of light, carbon dioxide, and water
molecules in the production of food and oxygen in photosynthesis?
Answer:
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.
The water cycle: 1. Name three important needs for water biomechanical mechanisms, habitat for plants and animals, participate in cycling of all materials used by living things 2. How is water distributed through the biosphere
Answer: 1.) The three important need for water includes:
--> it is important for biochemical mechanisms such as digestion and cellular respiration
--> it serves as a habitat for many species of plants and animals.
--> it participates in cycling of all materials used by living things.
2.) Water is distributed through the biosphere by WATER CYCLE.
Explanation:
Water is necessary for the maintenance of life which is distributed through the biosphere by a cycle known as the WATER CYCLE.
All living organisms contain a high percentage of water. Plants take up water form the soil in large amounts and lose most of it by transpiration. Only a small amount of the absorbed water is used in photosynthesis and other metabolic reactions. Animals take in water constantly from their food and drink. Like in plants, most of the water they take in comes directly from the non- living environment and not through the food chain. They lose most of this water in the air they breathe out, in faeces and urine. All living organisms release water during cellular respiration.
In nature, water circulates mainly within the abiotic ( non living) environment; only a small portion recycles through living organisms.
Water cycle is maintained mainly by the evaporation and condensation of water in the abiotic environment. Water that enters the biotic components of the ecosystem returns to the abiotic environment through respiration, decay, excretion and transpiration.

6.The development of antibiotic-resistant M. leprae is inevitable. Researchers are trying to develop antibiotics that would inhibit the biosynthesis of mycolic acids. Would this type of antibiotic be useful to treat M. leprae infections
Answer:
explanation below
Explanation:
Leprosy, known as Hansen’s disease, is a chronic infection that is caused by Mycobacterium leprae. This disease damages peripheral nerves and effect areas like skin, yes, muscles and noses. Antibiotics are used to treat the infection between 6 – 12 months. When infected people refuse to follow the treatment schedules given to them by the medical experts, there is usually the development of more antibiotic-resistant M. leprae.
M. leprae, just like tuberculosis, cell walls contain fatty molecules known as mycolic acids, which make the bacteria less susceptible to antibiotics.
Researchers have made remarkable progress in developing drugs such as ethionamide, isoxyl, thiolactomycin, and triclosan that are known to inhibit mycolic acid biosynthesis.
The development of these drugs are part of the tuberculosis drug discovery efforts (in the last one decade) which has been successfully applied to therapeutic targets in the unique mycobacterial wall.
Since morphology and cell wall of M. leprae does not differ remarkably from that of M. tuberculosis, antibiotic developed to inhibit the biosynthesis of mycolic acids would help to treat leprosy
Fire is an example of a living thing?
Answer:
Fire Is A Non-Living Thing.
Explanation:
People sometimes think fire is living because it consumes and uses energy, requires oxygen, and moves through the environment. Fire is actually non-living. The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells.

What is the dewpoint temperature when the
relative humidity is 30% and the air
temperature is 20°C?
Answer:
Dew Point Temperature: 1.9°C or 35.4°F
The dewpoint temperature when the relative humidity is 30% and the air temperature is 20°C is determined as 2°C.
What is dew point temperature?The dew point temperature is the temperature at which air must be cooled to become saturated with water vapor.
The dew point temperature is calculated as follows;
[tex]N = \frac{[ln(R_H/100) + [\frac{17.27T}{237.3 + T} ]}{17.27} \\\\N = \frac{[ln(30/100) + [\frac{17.27\times 20}{237.3 + 20} ]}{17.27}\\\\N = 0.00807\\\\D = \frac{237.3N}{1-N} \\\\D = \frac{237.3 \times 0.00807}{1-0.00807} \\\\D = 1.93 ^0C \ \approx 2\ ^0C[/tex]
Thus, the dewpoint temperature when the relative humidity is 30% and the air temperature is 20°C is determined as 2°C.

Which two factors have likely influenced global temperatures the most?
A: solar radiation
B: volcanic activity
C: agricultural activities
D: fossil fuel consumption
Answer:
B: volcanic activity
D: fossil fuel consumption
Explanation:
Fossil fuel consumption and volcanic activity are the two factors that has a great influenced on the global temperatures. Fossil fuel consumption is a human activity and volcanic activity both releases carbondioxide gas while burning. This carbondioxide gas is a greenhouse gas which block the reflected solar radiation and leads to increase in the surface temperature of the earth.

Compression of mortality is the extent to which an organ can preserve essentially normal function despite decreasing cell number or cell activity. Group of answer choices True False
Answer: False
Explanation:
Compression of mortality refers to the reduction over time with regards to the variance of the age of people at death.
The extent to which the organ can help in preserving normal function despite the fact that there's a reduction in the number or cell activity is referred to as compression of morbidity.
When morbidity is compressed, it should be noted that individuals can be expected to live healthier and longer as well.
Therefore, the statement is false
