Microbeads are tiny, smooth, plastic spheres found in common household products such as facial soap. These beads, measuring from

0.0004 to 1.24 mm, roughly the size of some fish eggs, are too small to be removed by water treatment systems. Thus, they end up in rivers, lakes, and other bodies of water. The accumulation of these microbeads is an environmental concern for aquatic biologists because microbeads
(1) make the lakes and rivers cloudy and dirty, affecting their appearance
(2) may stick to some household water pipes, preventing drainage problems
(3) could be mistaken for food by some species, working their way up the food chain
(4) could clog fishing nets, affecting the ability of fishermen to catch fish

Answer:

(3) could be mistaken for food by some species, working their way up the food chain

Explanation:

Microbeads, such as other microplastics, can affect wildlife in many ways, but mostly by

  • Ingestion
  • Introduction and transference in the trophic web
  • Interaction with other contaminants
  • Microinvertebrates, bacteria, and viruses colonize these microplastics and can be transported long distances.

Organisms like mollusks, crustaceans, fishes, birds, turtles, among many others, might confuse these elements with food and eat them. Microbeads might float or accumulate in sediments and be ingested by different benthonic species. The ingestion of microbeads by inferior links in the trophic web means a direct entrance in the trophic web where many superior links are affected too while feeding with already contaminated prey.

The ingestion of microbeads can cause a significant impact on the growth, development, and reproduction of freshwater and seawater species.  

Microbeads, like other microplastics, characterize for their durability in time and resistance, which means that the ones that are already in the oceans and rivers will last there for centuries.

explains respiration including the reactants and the products, its purpose and the organelle it occurs in.
ziro4ka [17]
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.

PLEASE HELP ME FOR 100 POINTS AND BRAINLIEST!!!
dmitriy555 [2]

Answer:

When comparing homologous structures, we are comparing the anatomy of one part of an organism to another and finding it to be structurally similar but functionally may be different. Let’s compare a couple of tetrapods, specifically a human arm and a cat arm.

Both the human arm and the cat arm have a single bone in the upper arm, which we call the humerus, followed by two bones in the forearm–the radius on the more medial side and the ulna on the more lateral side. Both arms also have a common wrist structure followed by a grouping of metacarpals and phalanges. All of these structures are similar; however, these structures do not have the same function. Cats are quadrupeds that use their arms for walking and maybe a little climbing and hunting for outdoor cats. Humans, on the other hand, use their arms and hands for gross motor movement like grabbing, hugging, and lifting, as well as fine motor movement like using tools or even communicating.

A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. But the whale’s “arm” is actually a flipper that it uses to swim while the bat uses its wing to fly.
