Question 1
Ugo [173]

Answer:

C Differences among temperature, air pressure, and density

Explanation:

Classification of the atmosphere layer will be different based on the temperature, air pressure, and density.  Generally, air pressure and density will go less at the higher layer, but the temperature varies greatly. Altitude and latitude define a location on earth, not the layer of atmosphere. Most weather just happens at the troposphere layer. The distance from ground level can be used as a rough estimate but not as precise criteria.

Answer:

Nutrient

Explanation:

Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.

Nutrient inputs to the system come from weathering of rocks, from windblown dust, and from precipitation, which can carry material great distances.​ Various amount of nutrients are transported or transfered from terrestrial ecosystems through erosion and then deposited in aquatic ecosystems such as oceans, seas, and associated lowlands.

Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

An infectious disease researcher isolates the pathogen responsible for an emerging disease. The microbe is grown in the lab. Preparation of the laboratory-grown microbe is treated with a lethal dose of ionizing radiation and then tested for its potential as a vaccine and this is  Inactivated type of Vaccine.

<h3>What exactly are pathogens?</h3>

Pathogens include viruses, bacteria, fungi, and parasites that can enter the body and harm the immune system. Among many additional viruses that can lead to serious illnesses are anthrax, HIV, the Epstein-Barr virus, and the Zika virus.

<h3>What is vaccination?</h3>

An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular infections.

<h3>Inactivated vaccine:</h3>

In inactivated immunizations, the disease-causing microorganism is eliminated.

Inactivated vaccines typically don't provide as strong of immunity (protection) as live vaccines. Therefore, it can take several doses (booster injections) throughout time to keep up your resistance to diseases.

Using inactivated vaccinations, you can guard against

  • Flu
  • Hepatitis A
  • Polio
  • Rabies
