Have a blessed day
The statement which is true for a radioactive isotope is " they break down quicker than stable isotopes because they are unstable and undergo decay.
What is radioactive isotope?A radioactive isotope is an isotope of an element which is under exposure to a radiation undergoes decay and breaks into lighter isotopes.
Radioactive isotopes are generally heavier and are unstable with short life time. They undergo radioactive decay by alpha/beta or gamma radiation to form stable lighter or smaller isotopes.
Therefore, option C that is, they break down quicker than stable isotopes is correct.

Answers
Answer:
Matter is made up of particles that are constantly moving.All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.The temperature of a substance is a measure of the average kinetic energy of the particles.A change in phase may occur when the energy of the particles is changed.There are spaces between particles of matter. The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together. These attractive forces are called intermolecular forces.

The diagram below represents a species of beetle (ladybug) with two different body colors labeled A and B. These beetles live on trees and are eaten by birds. The percentage of each body color in the population of this species is indicated. The habitat of this beetle population is a group of trees with light-colored bark. Based on the information provided, explain why the beetle population in this habitat contains a higher percentage of beetles with body color A.
Answers
Beetles are insects that belong to the superorder Endopterygota's Coleoptera order (/koliptr/). They can be distinguished from most other insects by the fact that their front pair of wings have solidified into wing-cases, or elytra.
What are beetles?Beetles are the most common type of insect. Beetles are everywhere. But beetles can be confused with other kinds of insects, especially some true bugs. Beetles differ from all other winged insects by having the first pair of wings hardened and thickened.
Some real bugs (Order Hemiptera) have wings that resemble beetles in some ways. However, true bug wings are only partially thickened and stiffened. True insect wings are translucent on the outside. The mouth parts of the two groups can also be used to distinguish them.
Because the bugs with body color A are able to blend into the habitat/trees better, which makes it harder for the birds to see.
There is one further difficulty with identifying beetles. Beetles go through a significantly different-looking immature (or larval) stage before emerging as winged adults.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.

C. Thinning ozone levels in the atmosphere always accelerate the rate of photosynthesis in plant life.
D. Thinning ozone levels in the atmosphere may lead to increased exposure to ultraviolet radiation at the Earth's surface.
Answers
Answer:A
Explanation:
Ozone acts as a protective sheet above the earth's atmosphere which trap the hazard UV rays from sun. Therefore, the a depletion in the ozone layer causes increased exposure to UV radiation. Thus option D is correct.
What is ozone?Ozone is O₃, formed by the reaction of nascent oxygen with the atmospheric dioxygen. Chemically it is a toxic gas and highly reactive. An umbrella like layer of ozone gas is present in the stratosphere of the atmosphere.
This ozone layer protect us from ultraviolet radiation from sun. The UV rays are extremely dangerous which causes skin burn, head ache, respiratory and reproductive problems and even cancer.
Ozone is capable of trapping these uv rays without reaching to earth surface. Hence, a depletion in ozone layer increase the exposure to UV-rays.

Answer:
Hey,
So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.

Organism: Jaguar
1. Jaguars live in a range of habitats, including arid scrubland, thick tropical forests, swamps, coastal mangroves, lowland river valleys, grasslands, and mixed-conifer forests. They gravitate toward areas near rivers and streams.
2. Habitat loss, wildlife trafficking, collisions with vehicles, and retaliatory killings by landowners and ranchers who fear that jaguars will kill their livestock have significantly lowered the population numbers of jaguars and threaten them with eventual extinction.
3. If jaguars were to go extinct, the number of these animals would perhaps increase, which might change the current ecosystem, from what it is now, to a new ecosystem that will adjust to the species left.
Biome 2: Desert
Organism: Camel
1. No matter the type, camels are usually found in the desert, prairie or steppe. Though many people think that camels only live in hot climates, they do well in temperature ranges from 20 degrees F (minus 29 degrees.
2. The sudden increase in camel populations could be also related to massive import of live animals. The Arabian Peninsula countries are among the main camel importing countries.
3. A mob of feral camels moves across arid land in the Australian Outback. The animals, introduced to the area in the 1800s, are causing enormous damage to the ecosystem. ... Camels also damage salt lake ecosystems, pollute waterholes, and destabilise desert dunes, which can lead to erosion. Meaning There would be less damage to the ecosystem.

What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
