Answer:
1 COSMETICS WITH MICROBEADS
2 COFFEE CAPSULES
3 WET WIPES
Explanation:
1.Plastic microbeads began to be introduced in cosmetics, toiletries and cleaning products in the 1970s, but it wasn’t until the 1990s that brands began to incorporate them in a massive way. Toothpastes, creams, lotions, shampoos and detergents began to include microbeads as the great innovation of the time for achieving an abrasive effect, replacing the nature-based materials in use until then.
2 Capsule coffee machines have revolutionized the breakfasts of millions of people, offering a convenient and practical option for preparing an espresso or latte with the same quality one finds in a café. Data from 2017 indicate that 29% of US coffee consumers use these machines, a figure that continues to grow.
3They started off being an invaluable aid for fathers and mothers when facing the messy moment of their baby’s diaper change, but soon they began to be reinvented as deodorants, cleansers, disinfectants and hand soap substitutes, and even as toilet paper for adults. Wet wipes have become a common item in many homes, but with a dramatic consequence: they help to create fatbergs, immense accumulations that block the sewerage networks and that are composed of 93% non-degradable wipes, together with fat, condoms and other similar items thrown into the toilet.
Life cycles occur in a variety of forms, all involving the exploitation of one or more hosts. Those that must infect more than one host species to complete their life cycles are said to have complex or indirect life cycles, while those that infect a single species have direct life cycles.
If a parasite has to infect a given host in order to complete its life cycle, then it is said to be an obligate parasite of that host; sometimes, infection is facultative — the parasite can survive and complete its life cycle without infecting that particular host species. Parasites sometimes infect hosts in which they cannot complete their life cycles; these are accidental hosts.
A host in which parasites reproduce sexually is known as the definitive, final or primary host. In intermediate hosts, parasites either do not reproduce or do so asexually, but the parasite always develops to a new stage in this type of host
Answer:
C
Explanation:
Light with energy above a certain point can be used to knock electrons loose, freeing them from a solid metal surface, according to Scientific American.
photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material
The formula written in the 3rd line above the picture is WRONG. Don't use it. Use the formula the way it's printed in the picture.
V = d / t
That means Speed = (distance) / (time)
The question tells us that v = 330 m/s
So you write 330 m/s in the equation in place of 'v', like this:
330 m/s = (distance) / (time)
The question also tells us that the time is 0.4 second
So you write 0.4 sec in place of 'time', like this:
330 m/s = (distance) / (0.4 second)
Finally, you take this, and multiply each side of the equation by (0.4 sec). Then it'll say
distance = (330 m/s) x (0.4 second)
As soon as you do that one single multiplication there with your pencil or your calculator, you'll have the distance.
This is either the 2nd or 3rd time you've posted this same exact question since last weekend. It can be solved THIS time exactly like the answers that were posted those other times.
The DOT in the picture is marked for the wrong choice. Use the formula that's printed in the picture, not copied above it.
