Explain how bacteria can be both harmful and helpful.
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.

observations and reasoning. Identify each statement as
an example of an observation or reasoning. If a statement
is false or invalid, identify it as such.
a. Most of the mass of the solar system is in the sun.
b. The sun is composed primarily of hydrogen and
helium.

the universe formed.
d. Most objects in the solar system orbit the sun in the
same direction.

Explanation:
In pea plants, the allele that produces purple flowers (P) is dominant to the allele that produces white flowers (p), and the allele that produces tall plants (T) is dominant to the allele that produces short plants (t). Two pea plants are crossed and produce 521 offspring, and the results of this cross are shown below:
Phenotype Number of offspring
Tall with purple flowers 291
Short with purple flowers 97
Tall with white flowers 101
Short with white flowers 32
Which cross would MOST LIKELY lead to this outcome?
Pptt × ppTt
pptt × PPTT
PpTt × PpTt
ppTT × PpTt
Answer: PpTt x PpTt
Explanation:
The cross PpTt × PpTt leads to the phenotype Number of offspring Tall with purple flowers 291 Short with purple flowers 97 Tall with white flowers 101 Short with white flowers 32, hence option C is correct.
What is a dihybrid cross?Two creatures that are identically hybrid for two characteristics are said to have mated to create a dihybrid cross. When an organism is heterozygous, it signifies that there are two distinct alleles present at a certain genetic location.
An attempt in producing two creatures that are identical hybrids for two qualities is a dihybrid cross.
The people with this sort of character are homozygous for that particular trait.
Therefore, to put it another way, a dihybrid cross is a union of two organisms that are heterozygous for two separate features, hence option C is correct.

Once assembled, what is the key to a protein's unique function?
Answer:
Once assembled, what is the key to a protein's unique function? The manner in which proteins fold is the key to their function
The endoplasmic reticulum is an important region where protein folding occur. Because proteins need to be appropriately folded into distinct structures, this is an essential biological function.
What is importance of protein folding?Proteins that are misfolded or are unfolded improperly impart to the pathophysiology of many illnesses.
Protein folding is a highly delicate process that is regulated by a variety of external stimuli, such as temperature, pH, chemicals, molecule crowding, electric and magnetic fields, and temperature.
These elements affect a protein's capacity to fold into the appropriate functional forms.
Therefore, Protein folding give unique properties to protein functions.

What type of energy has to do with a change in temperature?
Answer: changes in heat energy change temperature
Explanation: heat energy can be thought of as energy in individual atoms or molecules, which vibrate more as energy increases. Temperature is a measure of heat energy. For example, many substances expand as heat energy causes it atoms/molecules to vibrate more and occupy more space. We can use this property to measure energy as temperature by using the expansion of a liquid as in thermonmeters.

What is one way during the G0 phase that a mistake during the cell cycle could result in problens for the G0 phase?
The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.
Which muscle cells are often considered as G0 phase cells?Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle.
Mitosis is the procedure with the aid of which a mobile replicates its chromosomes after which segregates them, producing two identical nuclei in training for mobile division. Mitosis is generally followed by way of same department of the mobile's content material into daughter cells that have identical genomes.
The two phases of cell cycle are interphase in which DNA replication occurs, 3 stages of interphase are: G1 phase, S phase and G2 phase and mitotic in which division occurs phase. Mitosis occurs after the completion of DNA replication and doubling of chromosome number and cell contents and after mitosis, two daughter cells are produced of equal number of chromosomes.
Therefore, The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.

What is the energy source that allows photosynthesis to occur?
Answer:
[tex]\boxed {\boxed {\sf The \ sun }}[/tex]
Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.
