Explain why global efforts are being made to mass vaccinate populations and the importance of herd immunity in wiping out disease nationally and globally?

Answers

If you’re referring to the current Coronavirus pandemics, the reasons we want to mass vaccinate the population is to stop the spread by making it harder to find a host that it can use to replicate. The more times the RNA virus replicates, the more mutations are generated, the more likely a strain, that can escape the any immunity developed, can occur. Herd Immunity is what will help reduce the ability of a virus to spread. If the virus can’t find a host to replicate in (because the host is immune to the virus) the harder it is for the virus to spread.

Answer:

Zero Turbidity

Explanation:

High phostphate levels cause excessive algea growth and a decreased level of dissolved oxygen. High levels of nitrates are caused by animal or human waste and the overuse of chemical fertilizers. Low turbidity causes the water to be more clear so zero turbidity is the only right answer. I got it right on my test too

How does aerobic respiration differ from anaerobic respiration ?
I need long answer, and correctly explained.​

Answers

Answer:The difference between aerobic and anaerobic respiration.

Aerobic respiration  Anaerobic respiration

1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. 1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.

2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria. 2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).  

3. The end products are carbon dioxide and water. 3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid

4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules) 4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.

Anaerobic respiration is carried out by yeast and other anaerobic organisms like lactic acid bacteria, E. coli, Staphylococcus, Clostridium etc.

Based on the context in paragraph 4, fossil refers to ____________.

a. how igneous rocks were formed over time
b. a trace or print, or the remains of a plant or animal of a past age preserved in Earth or rock
c. layers of sediment building up over time and pressing down, forming rock


4. Sedimentary rock is the second category. These rocks cover most of Earth’s land. Sedimentary rocks are made of pieces of other rocks and shells. Erosion causes rocks to slowly wear away. Erosion can be caused by rain, wind, freezing, and plant roots. Sometimes small pieces of rock are made because of erosion. The small pieces of rock are called sediment. Rivers take sediment to oceans and lakes. The river drops the sediments as it slows down. The sediments settle to the bottom in layers. More and more layers of sediment are dropped over millions of years. The weight from the top layers turns the bottom layers of sediments into rock. This makes some sedimentary rocks look layered. Fossils are often found in sedimentary rocks.

Answers

Answer:

b. a trace or print, or the remains of a plant or animal of a past age preserved in Earth or rock

Explanation:

Fossils are remains or prints of extinct species that are slowly filled in with sediment over time.

Answers

What is the meaning of pathophysiology

Diabetes can result in inadequate blood flow, nerve damage, and severe foot issues.  One method to help prevent it is by controlling your blood sugar.

What is Diabetes?

A collection of illnesses known as diabetes mellitus alter how the body requires blood sugar. The cells that comprise the tissues and muscles rely heavily on glucose as a source of energy. 

Each form of diabetes has a different primary etiology. Yet, diabetes can result in an excess of blood sugar regardless of the type you have. Serious health issues can result from an excess of sugar in the blood. Diabetes can result in inadequate blood flow, nerve damage, and severe foot issues. Diabetes that is not controlled can result in amputations, mainly of the legs, foot, or toes. One method to help prevent it is by controlling your blood sugar.

Therefore, diabetes can result in inadequate blood flow, nerve damage, and severe foot issues.
