What to do if you get ulcerations in your throat from doxycycline?

Anon25 [30]

<span>Its called Doxycycline-induced esophageal ulcer. Its not common. I have been taking Doxy for many years for acne without any complication. Then one night I took a single pill, drank half a glass of water, and went to bed. I woke up with mild heartburn. A few days later, I was in immense pain. I felt burning up and down my whole chest. I was bloated, gassy, and couldnt burp. The pain was so severe, it caused me have a migrane. The pill dissolved in my esophagus, and caused an ulcer. It was my fault for not drinking a full glass of water, and going straight to bed. Im in treatment now, and am scheduled for an esophagogastroduodenoscopy. Im feeling a little better already after the first day of treatment, but ulcers take 4-8 weeks to heal.</span>

1. Most familiar life forms live in regions of biomes that humans inhabit. (1 point)

Genrish500 [490]

Answer:

1. The first statement is true. A biome is defined as a large set of naturally occurring plants and animals occupying a major habitat. For e.g. forest, dessert, grasslands etc.

2. The given statement is True. Biodiversity is defined as the variety of plants and animals exists or existed in the world or in any specific habitat. The high level of biodiversity is important and beneficial for the environment.

3. This statement is False. Outside force such as earthquake, zone hole etc can certainly cause changes in the organism. For example, UV rays can cause cancer in an organism, dark colorization of peppered moth during industrial revolution.

4. It is True as species is defined as a group of organisms capable of interbreed and share common characteristics. It is the basic unit of biological classification. For example, <em>sapiens </em>is the species of human being.

5. Yes, the given statement is true. Charles Robert Darwin famous naturalist, biologist, and geologist. He was best known for his work in the field of evolution and gave the theory of natural selection. He is also known as the father of evolution.

6. No, all scientists were not agreed with Charles Darwin, for example, Lamarck, Weismann etc. However, Neo-Darwinism was much more accepted that Darwin original theory. Hence, the given statement is false.

7. Natural selection is one of the process of evolution. It sates that organisms better suited and adapted to their environment have better chances of survival. Organisms acquire new characteristics over the generations in order to adapt in a environment. Hence, the given statement is false.

8. The statement is true. However, recently it has been found that there are some bacteria which can inhabit the extreme conditions. They are known as extremophiles, for example, halophiles, thermophiles etc.

9. Yes the statement is true. These organisms are known as extremophiles, for example, halophiles (which live in high saline conditions), thermophiles (can live in high temperatures) etc.

10. This statement is false as there are many species which have not been discovered yet.

What might happen if some lysosomal enzymes are absent?

murzikaleks [220]

Answer:

Explanation:

The main fuction of lysosomal enzymes like lipases ,proteases, carbohydrases is to hydrolyse/digest various unwanted material in the cell. And sometimes to digest some nutrient in the cell.

These enzymes are capable of digesting carbohydrates,proteins,lipids and nucleic acids. Lysosomal enzymes are produced by a memberane bound cell organel called lysosome.

WHAT IF LYSOSOMAL ENZYMES ARE ABSENT:

==＞ If lysosomal enzymes are absent then build up of various unwanted substances increase to a abnormal level, which may increase toxicity in the cell.

==＞build up of various dead or unwated cells in the body will increase,since lysosome have the capacity to digest its own cell.

==＞ absence of lysosome will will cause the cells to starve,since most of the nutrients in the cells are digested by lysosome enzyme.

==＞ Can cause a high risk of disease,since lysosome digest its own cell if it is infected with some microbial activity.
