Explain how bacteria can be both harmful and helpful.

Answers

Answer 1

The species of bacteria that colonize our respiratory and digestive systems help set up checks and balances in the immune system. White blood cells police the body, looking for infections, but they also limit the amount of bacteria that grow there. Likewise, bacteria keep white blood cells from using too much force. Bacteria also help out by doing things cells are ill-equipped to do. For instance, bacteria break down carbohydrates (sugars) and toxins, and they help us absorb the fatty acids which cells need to grow. Bacteria help protect the cells in your intestines from invading pathogens and also promote repair of damaged tissue. Most importantly, by having good bacteria in your body, bad bacteria don’t get a chance to grow and cause disease.

Some species of bacteria in your body can result in diseases, such as cancer, diabetes, cardiovascular disease, and obesity. Usually, these diseases happen only when the normal microbiome is disrupted, but that can occur even from antibiotics. Antibiotics kill bacteria, and some of those will be good bacteria that we need to protect our health. When that happens, the bad bacteria that normally are kept in check have room to grow, creating an environment ripe for disease.

Bad bacteria can exist at low levels in your body without causing harm or can grow too much and wreak havoc. Staphylococcus aureus can cause something as simple as a pimple or as serious as pneumonia or toxic shock syndrome. P. gingivalis can cause gum disease, and was recently linked to pancreatic cancer (read our article find out more). Similarly, when not suppressed by good bacteria, Klebsiella pneumonia can cause colitis, and subsequently lead to colorectal cancer.

In addition to allowing disease-causing bacteria to flourish, the elimination of good bacteria throws  the immune system out of whack. The result can be simple allergies or very debilitating autoimmune diseases. Without the right balance of bacteria, your body might suffer from constant inflammation.

Inflammation is the body’s alarm system, which calls white blood cells to heal a wound or to get rid of infection. Chronic inflammation, however, can make the body more susceptible to autoimmune diseases and cancer, such as causing inflammatory bowel disease which if uncontrolled can cause colon cancer.

If water was removed from a plant's environment what would happen to the plant's glucose production?​

Answers

Answer:

It would cease

Explanation:

If water is removed from a plant's environment, the plant's glucose product will cease. This implies that the plant will stop producing glucose.

Water is an essential ingredient for the production of glucose by plants. During the process of photosynthesis, green plants manufactures their food in the presence of sunlight. The water combines with carbon dioxide to produce glucose oxygen gas using sunlight energy. Without water, this reaction will not be possible to take place. Therefore, the production of glucose stops when there is no water.

How could one determine if two
unidentified organisms share a common
ancestor?

Answers

Answer:

Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.

Explanation:

DNA

They can look at the DNA it's the most common one.

There are 4 pieces of evolution and they are

Fossils , Geography , Embryos / DNA , Anatomy

Fossils: Physical remains of species , Determine age, location,  environment

Deeper layers = older

Geography: Proves species share common  ancestors, depending on where

they live

DNA: BEST evidence because it’s the  MOST ACCURATE

Similarities in the early stages of  development

Similarities in DNA

More similarities = closely related

More differences = not related

Anatomy: Compare body parts of different  species to see how they evolved

3 different structures:

Homologous (same structure,  different function)

Analogous (similar structure,  different organisms)

Vestigial (body parts that no  longer serve a purpose)

All of that are in evolution

Can someone explain the Punnett square ?

Answers

Answer:

so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically  the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB.  next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.

Explanation:

the main points.

in this example, i used B to be the dominant gene and b to be the repressed/ submissive gene. you always put the dominant gene letter before the repressedmake sure you fill the squares in properly. in this one, you should have 3 BB and 1 Bb. this shows that the gene set BB is going to showwhen you fill in the squares, the first top letter and the first side letter fill in the top left square.the first top letter and the second side letter go left bottom.second top letter and first side letter go in right top.second top and second side go in right bottom.always place the dominant gene first in the punnet square.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell?

Answers

The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.

S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.

Which of the following correctly identifies a lymphatic organ and describes how it
can fight cancer? (2 points)
1) Lymph vessel; removes fluid from tissues
2) Lymph trunk; returns lymph to the blood
3) Spleen; replaces damaged red blood cells
4) Thymus; exposes lymphocytes to antigens

Answers

All of the statements correctly identify a lymphatic organ. In vertebrates, the lymphatic organs, also known as the lymphoid system, are an organ system that is a part of the immune system and works in conjunction with the circulatory system.

The Lymphatic OrgansLymphatic vessels, which are found all over your body and transport lymph away from tissues, are a network of capillaries (microvessels) and a huge network of tubes.By emptying into the corresponding subclavian veins, the lymph ducts, which are formed by the lymph trunks, restore lymph to circulation.Red blood cells that are outdated or damaged are eliminated by the spleen, which also removes cellular waste from circulation.Training specific white blood cells known as T-lymphocytes or T-cells is the thymus gland's main job.

Hence, all of the statements correctly identify a lymphatic organ.

How lymphatic system fights Cancer?Regional lymph nodes, which are predictive of distant organ metastases and poor survival, are accessible to tumor cells via lymphatic arteries.As the lymph fluid moves through the lymph nodes, it is filtered. B cells and T cells, two types of white blood cells, assault any viruses or bacteria they discover in the lymph.

The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers. (p + q = 1, p2 + 2pq + q2 = 1)

Answers

Answer:

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392
