Answer:

Takes place in the cytoplasm;
Produces a net gain of 2 ATP;
The splitting of a glucose molecule.

Explanation:

Glycolysis is the first step in cellular respiration, and as its name induces, it represents the breakdown of the glucose molecule. It is an <u>anaerobic</u> stage, that is, it does not use oxygen. The glycolysis step occurs in cytosol (cell cytoplasm).

It can be divided into two parts: In the first, there is the energy expenditure (2 molecules of ATP), and in the second, energy production occurs (4 ATP molecules are produced).

Glycolysis is a low energy step since it produces only 4 ATP molecules. However, its process consumes 2 ATP molecules, resulting in a balance of only 2 ATP at this stage.

Give me another real-life example for each type of symbiotic relationship<br>

olga55 [171]

Answer:

Mutualism: both partners benefit. An example of mutualism is the relationship between the Egyptian plover and the crocodile. In the tropical regions of Africa, the crocodile lies with its mouth open. The plover flies into its mouth and feeds on bits of decaying meat stuck in the crocodile’s teeth. The crocodile does not eat the plover. Instead, he appreciates the dental work. The plover eats a meal and the crocodile gets his teeth cleaned. Coincidentally, the Egyptian plover is also known as the crocodile bird.

Commensalism: only one species benefits while the other is neither helped nor harmed. For example, remora fish are very bony and have a dorsal fin (the fin on the back of fish) that acts like a suction cup. Remora fish use this fin to attach themselves to whales, sharks, or rays and eat the scraps their hosts leave behind. The remora fish gets a meal, while its host gets nothing. Selfish, sure, but neither gets hurt.

Parasitism: One organism (the parasite) gains, while the other (the host) suffers. The deer tick is a parasite. It attaches to a warmblooded animal and feeds on its blood. Ticks need blood at every stage of their life cycle. They also carry Lyme disease, an illness that can cause joint damage, heart complications, and kidney problems. The tick benefits from eating the animal's blood. Unfortunately, the animal suffers from the loss of blood and nutrients and may get sick.

Ddt was widely used as a pesticide for 20 years. Its use was banned after studies showed severe side effects were evident in hum

emmasim [6.3K]

Answer:

One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.
