Elaborate on the disease Syphilis. Please and thank you

Answers

syphilis is a bacterial infection usually spread by sexual contact. The disease starts as a painless sore typically on your genitals, rectum or mouth. Syphilis spreads from person to person via skin or mucous membrane contact with these sores.

During the months of July, August, and September, when the squirrels are more active we would expect the artic squirrels:


A) To produce more O2 when compared to other months.

B) To have a higher output of CO2.

C) To produce less water.

D) Increase in the output of glucose.

Answers

Answer:

B) To have a higher output of CO2.

Explanation:

We would expect the artic squirrels to produce a higher output of CO₂. As with most heterotrophs, the by-product of their respiratory activities is the formation of carbon dioxide gas.

They use oxygen gas to break down glucose. The process releases energy for their life activities. The waste product is usually carbon dioxide which enters back into the ecosystem as a waste.

READING TOOL Make Connections Fill in the concept map to show the
organization of a chloroplast. Then below, answer the questions to describe how the
different parts are related to each other.
Chloroplast

Answers

Answer:

Chloroplast -----membranes----------internal

                                              ---------external

                   ----- Tylacoids-------------Grana

                   ----- Stroma

You will find the complete concept map in the attached files

Explanation:

The chloroplasts are limited by two membranes, the internal and the external membranes. Both of them are separated by the intermembrane space.

In the interior of the organelle, thylakoids are composing the third system of membranes. In the interior of thylakoids, there is an additional compartment named thylakoid space. This membrane system forms piles, known as grana. Different grana structures connect to each other by a longer thylakoid membrane. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.

Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.

To fill in the diagram you will need to show the composition of the chloroplast. Therefore, you should show the internal and external membranes, the thylakoids, the grana, and the stroma.

We can arrive at this answer as follows:

Chloroplasts are organelles present in plant cells, they are very important in the photosynthetic process.Chloroplasts have two membranes, an internal and an external one, which limits the entry and exit of substances.Inside the chloroplasts are the thylakoids, which are formed by structures called grana, which form numerous piles, which resemble towers.The unoccupied space within the chloroplast is filled with a fluid called the stroma.

In the figure below you can see how this diagram can be filled.

List the four types stem cells, give an example of each type, and explain how much each type can differentiate.

Answers

(Sorry for the long answer lol but hopefully this helps)

Embryonic stem cells

Embryonic stem cells are obtained from the inner cell mass of the blastocyst, a mainly hollow ball of cells that, in the human, forms three to five days after an egg cell is fertilized by a sperm. A human blastocyst is about the size of the dot above this “i.”

In normal development, the cells inside the inner cell mass will give rise to the more specialized cells that give rise to the entire body—all of our tissues and organs. However, when scientists extract the inner cell mass and grow these cells in special laboratory conditions, they retain the properties of embryonic stem cells.

Embryonic stem cells are pluripotent, meaning they can give rise to every cell type in the fully formed body, but not the placenta and umbilical cord. These cells are incredibly valuable because they provide a renewable resource for studying normal development and disease, and for testing drugs and other therapies. Human embryonic stem cells have been derived primarily from blastocysts created by in vitro fertilization (IVF) for assisted reproduction that were no longer needed.
Tissue-specific stem cells

Tissue-specific stem cells (also referred to as somatic or adult stem cells) are more specialized than embryonic stem cells. Typically, these stem cells can generate different cell types for the specific tissue or organ in which they live.

For example, blood-forming (or hematopoietic) stem cells in the bone marrow can give rise to red blood cells, white blood cells and platelets. However, blood-forming stem cells don’t generate liver or lung or brain cells, and stem cells in other tissues and organs don’t generate red or white blood cells or platelets.

Some tissues and organs within your body contain small caches of tissue-specific stem cells whose job it is to replace cells from that tissue that are lost in normal day-to-day living or in injury, such as those in your skin, blood, and the lining of your gut.

Tissue-specific stem cells can be difficult to find in the human body, and they don’t seem to self-renew in culture as easily as embryonic stem cells do. However, study of these cells has increased our general knowledge about normal development, what changes in aging, and what happens with injury and disease.
MESENCHYMAL STEM CELLS:
You may hear the term “mesenchymal stem cell” or MSC to refer to cells isolated from stroma, the connective tissue that surrounds other tissues and organs. Cells by this name are more accurately called “stromal cells” by many scientists. The first MSCs were discovered in the bone marrow and were shown to be capable of making bone, cartilage and fat cells. Since then, they have been grown from other tissues, such as fat and cord blood. Various MSCs are thought to have stem cell, and even immunomodulatory, properties and are being tested as treatments for a great many disorders, but there is little evidence to date that they are beneficial. Scientists do not fully understand whether these cells are actually stem cells or what types of cells they are capable of generating. They do agree that not all MSCs are the same, and that their characteristics depend on where in the body they come from and how they are isolated and grown.
Induced pluripotent stem cells

Induced pluripotent stem (iPS) cells are cells that have been engineered in the lab by converting tissue-specific cells, such as skin cells, into cells that behave like embryonic stem cells. IPS cells are critical tools to help scientists learn more about normal development and disease onset and progression, and they are also useful for developing and testing new drugs and therapies.

While iPS cells share many of the same characteristics of embryonic stem cells, including the ability to give rise to all the cell types in the body, they aren’t exactly the same. Scientists are exploring what these differences are and what they mean. For one thing, the first iPS cells were produced by using viruses to insert extra copies of genes into tissue-specific cells. Researchers are experimenting with many alternative ways to create iPS cells so that they can ultimately be used as a source of cells or tissues for medical treatments.

Four types stem cells are :

Embryonic stem cells.Tissue-specific stem cells.Mesenchymal stem cells.Induced pluripotent stem cells.

After photosynthesis, energy that the coral can use is stored in
molecules of?

Answers:
O2
CO2
H2O
C6H12O6

Answers

Answer:

Energy is stored in glucose molecules C6H12O6

Explanation:

Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of photosynthesis. These molecules, like the monosaccharide glucose, store converted solar energy as stable  chemical energy in covalent bonds.  In covalent bonding, the elements share electrons with each other.

These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.

Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).  

Eg. for aerobic respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

3. Climate change has been a topic repeatedly mentioned in our study of Marine Science.

How does Jackson express the impact that climate change has on corals? Based on how

he uses it, what do you infer the word symbiosis to mean?

Answers

Answer:

Climate change lead to the destruction of corals due a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.

Symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.

Note: The study material was not provided.

Explanation:

Greenhouse gas emissions from human activities have led to an increase in global surface temperature. This has resulted in a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.

The warming of the oceans poses a great threat to life and activities in the ocean. Coral reefs especially are affected by a warming of the ocean in the following ways:

mass coral bleaching- with increase in ocean temperature, corals remove the algae living in association with them that are responsible for their colour, thereby turning corals white. With prolonged bleaching periods, the corals eventually eventually die .Sea level rise: with rise in sea level comes a likelihood of increase in flow of sediments into the sea. This sediments when deposited on corals found near land suffocates and kill the corals.Changes in storm patterns: stronger and more frequent storms can lead to a destruction of coral reefs. Increase in the acidity of oceans results in death of corals.

Corals and algae exist in a symbiotic (mutualistic) relationship in coral reefs. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.

Therefore, symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.
