Answer:
D. Division of body cells results in a greater variety of traits
Explanation:
Since sexual reproduction occurs between two organisms their traits are combined to form a new individual who has similarities and differences to both parents.
Answer:
D All of the above
Explanation:
Like our bones, bones in fish can provide general protection and support to their body.
(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)
The bone is also where the muscles will attach to, which allows for movement.
(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)
Bones can also protect the fish's brain.
(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)
Hello,
Please find below a short summary on the subject you have been assigned. This will help you in completing your project and also give you an overview on the current research on this subject.
Food additives are chemical substances added to food in order to either maintain or improve its physical characteristics such as taste, texture, appearance and even freshness.
The long term effects that these substances have on the human body are still largely unstudied. According to the hypothesis called "chemical obesogen", these synthetic compounds are contributing factors to the global obesity epidemic.
Although evidence-based scientific research is still lacking, the support for this hypothesis is growing as many of these additives have been found to disturb the body's endocrine functions.
Furthermore, artificial preservatives used today may increase the risk of inflammatory bowel disease. This has been shown by a study on mice in which the food additives known as emulsifiers (carboxymethylcellulose and polysorbate-80) have been shown to affect the animal's health.
Due to these chemicals, the mice not only became obese but also developed metabolic problems such as glucose intolerance. It seems that these chemicals affect the gut bacteria population in a negative way, as mice lacking gut bacteria did not become ill.
The mice study was followed by another study in which the human simulated through a series of flasks. Under the influence of the emulsifiers arboxymethylcellulose (E566 on EU labels) and polysorbate-80 (E433), the levels of bacterial protein called flagellin increased. This protein is known to cause inflammation at high concentrations. The next step in the study will be the first human trials.
Due to the long road our food takes from the farm to our table more extensive research is required. There are thousands of compounds that change the biochemical properties of the plants and animals that constitute our diet. The effects of the degradation and accumulation of these compounds are still unknown and thus many more studies and approaches are required in order to insure healthy food and stop the current obesity epidemic. Everything that is added to our food should be carefully analyzed.
A symbiosis is an evolved interaction or close living relationship between organisms from different species, usually with benefits to one or both of the individuals involved.
Respiration is the transformation of glucose to ATP, which is energy that the body can use.
Respiration consists of several steps: glycolysis, TCA/Krebs/Citric acid sycle and at last the oxidative phosphorylation.
The molecules needed for this to happen is water, oxygen (O2), NADH, ATP and glucose.
