Recovery from the 2008-2009 recession was agonizingly slow. what factors might have constrained faster growth?

Answers

Recovery from the 2008-2009 recession was agonizingly slow due to the following factors:

1. The recession had an impact on most of the industrialized West, not only the United States. As the recession spread to Europe, the United States's biggest market, it had a 360 degree impact on America's exports as well.

2. The US was spending a lot on the Iraq and Afghanistan wars. While this was theoretically supporting millions of jobs in the war industry, for the average person, there was no benefit. Billions that could have been used to help people, were used elsewhere.

3. Rising debt was also a problem. The recession opened up the hidden truth behind America's prosperity, the debt problem. Most people and institutions were spending war more than what they had and when the debt started to mount up, there was very little flexibility left.

4. We also have to admit that the response for the recession was too late. Firstly, the government should not have let a recession happen. However, once it did, they waited for Lehman brothers to completely fail before taking concrete actions.

The evolution of new organs usually builds on preexisting structures that are modified in form and sometimes function. The embryos of fish, amphibians, reptiles, birds, and mammals all have pharyngeal pouches or gill slits. These pouches develop into gills in adult fish and they are used to absorb oxygen from their watery environment. These same pouches become parts of the in_________ humans. a) eyes and lungs
b) ear and throat
c) eyes and nose
d) lungs and heart

Answers

Answer:

lungs and heart

Explanation:

lungs and heart is the answer because human lungs is use for gas exchange during respiration or while you breathe. When humans breathe, the lungs absorb oxygen from the inhaled sir into the blood and carbondioxide leaves the blood when we breathe out. The heart pumps the blood, and oxygenated blood are carried in the blood when air is inhaled and carbondioxide leaves the blood when you exhale. The blood carries nutrients and oxygenated blood. Therefore, lungs and heart work hand in hand in absorbtion of oxygen from it's environment.

Which of the folowing epithelia and/or cell surface modifications are present in large bronchi? (Check all that apply) a. clia
b. goblet cells
c. microvilli
d. pseudostratified ciliated columnar epithelium
e. stratified squamous epithelium

Answers

Answer:

d. pseudostratified ciliated columnar epithelium

Explanation:

Pseudostratified ciliated columnar epithelium

It is a type of epithelium , which is made up of cells of single layer .

The function of Pseudostratified epithelia is secretion or absorption .

Pseudostratified epithelia secretes mucus and cilai helps the movement of mucus .

The nucleus of these cells are present at different levels , thereby creating an illusion of cellular stratification .

Answer:

b. Goblet Cells

Explanation:

There are 3 types of epithelial cells in the large bronchi, namely:

1. Goblet Cells

2. Ciliated Cylindrical Cells

3. Brush Cells

Goblet cells are epithelial cells where the main function is to secrete mucin. These cells have a certain structure namely the rough endoplasmic reticulum, and mitochondria, nuclei, and other cell organelles are found in the basal cell section.

These cells are well distributed in the epithelial lining of the walls of organs such as the trachea, bronchi, small intestine, upper eyelid membrane, large intestine, and others. The ultimate goal is to lubricate these organs for the smooth functioning of them.

The most important function of goblet cells is to secrete mucus which is a thick liquid and consists of a glycosylated protein mucin that is suspended in an electrolyte solution. The main function of mucus which protects against stress and chemical damage, trapping and eliminating microorganisms and particles.
