Answer:
A
Explanation:
Prairies are unique ecosystems dominated by grasses and other non-woody plants called forbes. ... A prairie ecosystem includes all the living components-- plants and animals--and all the nonliving components-- sun, water, fire, soil, and--nutrients.
Bearded iris plants require a lot of sun and a mediocre amount of water. They thrive in neutral pH soil and is quite sensitive to insects/pests. The biggest improvement that can be made in the plant nursery to further their growth is to have the sufficient amount of watering but most importantly, adjust the greenhouse so that there is more sunlight entering the enclosure/ there is more lighting in general (long day setting).
OPTIONS:
a. When there are just two other people at the party.
b. When everyone is wearing a nametag.
c. When there are more than 50 people attending the same party.
d. When the need for help from the person who is having a heart attack is very clear
Answer:
c. When there are more than 50 people attending the same party.
Explanation:
Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.
In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.
The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>
<span>If you examine a rock sample and observe fossils in it, the type of rock the sample represent in C - sedimentary. Igneous rock is a melted and cooled rock and there are no remains of any kind of fossils. Still, can be found some fossils traces in some metamorphic rocks with the lowest grade of metamorphism but those are very very rare.
the answer is C, sedimentary </span>
Where's the evolution?
The physics of light affects not just how blue water looks to us, but how the animals living in the world's oceans, lakes, and rivers are able to find food and each other — and this, in turn, can impact their evolution. Natural selection favors traits that perform well in local environmental conditions. Many fish species, for example, have evolved vision that is specifically tuned to see well in the sort of light available where they live. But even beyond simple adaptation, the physics of light can lead to speciation. In fact, biologists recently demonstrated that the light penetrating to different depths of Africa's Lake Victoria seems to have played a role in promoting a massive evolutionary radiation. More than 500 species of often brightly colored cichlid fish have evolved there in just a few hundred thousand years!
