Answer:
Lead is the major pollutants of high-tech gadgets, occupying 40%, while other metals 75%.This is because Pb forms lager components of these gadgets.For example a desktop computer contains about 10 pounds of Pb.
The lead to recycle these material to prevent pollution is important.
Explanation:
Answer:
Heavy metals such as plumb, mercury, arsenic, etcetera.
Explanation:
There are many heavy metals used in high-tech gadgets, such as mercury, cadmium, arsenic, among others.
The pollution produced by industries, technology, agriculture, mining industry, and the indiscriminate use of fertilizers and other chemicals on land is increasing the amounts of heavy metals. These substances are incorporated in rivers, lakes, underground water, vegetables, and animals. These pollutants alter the trophic chain

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be
present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

As a population of a species increases within a territory, which of the following most likely also increases?
A-immigration
B-carrying capacity
C-food supply
D-competition
Answer:
D) competition
Explanation:
They are going to be competing for their survival.
Hope this helps! :)
With the increase in the population of a species, the competition between them also increases.
How competition affect a population?An association between two or more individuals of the same population or two or more populations in which each negatively influences the other in access to a restricted resources like food, shelter, water, mates, nesting, etc is termed competition.
When the size of a population increases, one can witness more intense competition between the individuals of the population. The influence of competition is generally density-dependent, that is, at greater population density, there is an increase in competition. This will negatively affect the size of the population.
Thus, the correct answer is option D, that is, competition.

Given the discussion thus far of commensalism and parasitism, would parasitism be an accurate way to describe the relationship between the strangler fig and the cypress tree?
please help me
The relationship between the strangler fig and the cypress tree closely resembles one of parasitism but is not. It is considered commensalism.
Parasitism is when one organism uses another as a host in order to survive, which generated negative impacts for the host, which will usually end in death. The strangler fig uses the tree as a host in order to sustain itself structurally but does not siphon nutrients from the tree or directly kill it, therefore it is not a form of parasitism.
Commensalism is described as a relationship between two organisms, in which the benefits are gained by only one of the members, but neither of the two is harmed in any way.
The relationship between the strangler fig and the cypress tree is best described as commensalism, given that although the strangler fig does eventually cause the tree to die by encircling its roots and not allowing it to grow, it does not kill the tree directly in order to survive.

Answer:
It's better to answer in points...
Explanation:
Here the answer goes..
Bacteria are good as well bad for human body.For muscle development it is needed as it have some properties of muscle repairing.As, Bacteria is unicellular micro organisms. It have cell wall. The bacteria which are beneficial they defence the unnecessary bacteria and increases our immune which helps to repair muscles.Bacteria break down biological waste and they build up strong immune system. They control our mechanism for muscles.These were some reason.

What role does cellular respiration play in the carbon cycle?
Answer:
Cellular respiration is the process by which organic sugars are broken down to produce energy. It plays a vital role in the carbon cycle because it releases carbon dioxide into the atmosphere. This means that cellular respiration can be thought of as the opposite of carbon fixation in the carbon cycle.

5.explain mastication peristalsis segmentation and the release of hormones and enzymes necessary for digestion
Answer:
Ingestion starts both chemical and mechanical digestion.The digestion process begins with ingestion. The teeth starts the process of digestion by masticating food. Mastication makes easier swallowing and faster chemical breakdown. During mastication, salivary glands secrete saliva to soften the food. Saliva contains the salivary amylase enzyme, which digests carbohydrates, and mucus, which softens food into a bolus.
Peristalsis is a series of wave-like muscle contractions that moves food. Segmentation involves contractions of the circular muscles in the digestive tract, and Mastication breaks down food so that it can go through the oesophagus to the stomach.
Hormones - The hormones released by the pituitary gland are gonadotropins (LH and FSH), growth hormone (GH), thyroid stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), prolactin, antidiuretic hormone and oxytocin.
Enzymes - Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
Pepsin, produced in the stomach. Pepsin helps break down proteins into amino acids.
Trypsin, produced in the pancreas. Trypsin also breaks down proteins.
Pancreatic lipase, produced in the pancreas. It is used to break apart fats.
Explanation:
So we can conclude that,
mastication peristalsis segmentation is
breaking down food in a wave like muscle contractions of the circular muscles in the digestive tract.
Btw I am not really sure about it.
Mark as brainliest!
Answer:
Large food molecules (for example, proteins, lipids, nucleic acids, and starches) must be broken down into sub units that are small enough to be absorbed by the lining of the alimentary canal. This is accomplished by enzymes through hydrolysis. The many enzymes involved in chemical digestion are summarized
