List and describe the characteristic and position on the periodic table of halogens.
Answer:
Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to high electronegativity and high effective nuclear charge. Halogens can gain an electron by reacting with atoms of other elements. Fluorine is one of the most reactive elements.
Answer:

Your alien friend from planet Xenon is visiting and wants to learn how to breed pea plants. You show your friend a recent batch of pea plants with purple flowers that you grew by crossing plants that had purple flowers with plants that had white flowers. Your Alien friend is confused as to why all your plants have purple flowers. How would u explain in the simplest way possible what happened? Hint: think about parents passing on alleles and dominant vs recessive. ANSWER ASAP FOR BRAINLEIST
Answer:
You have a trait (plant color) and you have two possible outcomes for it (purple and white). You know that some alleles for white were present in one of the parent plants, so you know they must be present in the offspring too. But they're expression is covered up by the purple alleles from the other plant, so you know that purple is dominant to white.

parasitic plant and insecticide plant defination
parasitic plant = A parasitic plant is one that survives at the expense of another, often living and growing on and over the host plant, while siphoning off the other plant’s nutrients and water, and sometimes blocking access to sunlight.
insecticide plant = Insecticide, any toxic substance that is used to kill insects. Such substances are used primarily to control pests that infest cultivated plants or to eliminate disease-carrying insects in specific areas. insecticide application. A farmer sprays insectides in a rice paddy in Japan.
Who benefits from this relationship? Parasitism

the parasite benefits, and the host is harmed; however, the host is not generally killed.
Explanation:
Killing the host would be bad for the parasite, as it would have no place to live.

How are decreasing amounts of sea ice particularly harmful to mother polar bears and their cubs?
Answer:
Every winter, Arctic sea ice grows around the pole, its frozen tendrils threading along northern coasts. Right now sea ice has just passed its peak coverage for the year, and will begin to shrink with the coming of spring. It’s a crucial time for polar bears, whose food supply is inextricably linked to sea ice.
And in recent decades, sea ice has been shrinking faster than ever. According to the National Snow and Ice Data Center, 2019 has the seventh-lowest sea ice cover in the Arctic since they began collecting satellite data 40 years ago.
This year “doesn't break any records, but it's the trend that matters,” says University of Alberta polar bear scientist Andrew Derocher. “The downward trend in Arctic sea ice across all months is the concern,” he says, and “now we wait to see what spring conditions bring.” (Read more about global warming’s link to polar bears.)
A cold spring allows ice to linger, giving polar bears easier access to one of their favorite foods: seals. A warm spring cuts short the availability of their food super-highway....

3.ecosystem
4.habitat
Answer:
4.habitat
Explanation:
Habitat is the place or environment in which organisms normally lives and grows. Habitat may be small for small size organisms and large for large size organisms. In these habitat, the organisms lives because of the suitable environmental conditions that allows growth and survival of organisms in that environment. If the habitat is no longer suitable for the growth of organisms the organisms migrate from that area to another suitable area.
