(1 point) Responses the changes that occur in organisms over time the changes that occur in organisms over time the process of pollen moving from place to place the process of pollen moving from place to place when an animal is attracted to a flower when an animal is attracted to a flower when a sperm cell and egg cell come together
when a sperm cell and egg cell come together
Specialization can be both limiting and beneficial. How would a plant species benefit from a pollinator that only visits the flowers of that plant species?(1 point) Responses the flowers always having a pollinator the flowers always having a pollinator less competition for pollinators with other species less competition for pollinators with other species decreased self-fertilization, allowing for greater genetic variation decreased self-fertilization, allowing for greater genetic variation less competition for pollinators within the species
less competition for pollinators within the species
Sometimes, plants will reward their pollinators with something that benefits them. What is an example of a plant attractant that is also a pollination reward?(1 point) Responses nectar nectar vibrant colors vibrant colors pollen pollen sweet odors sweet odors
nectar
Add: 12(x+4)+14(4x−2) . Answer should be in mixed number form
To simplify the expression 12(x+4) + 14(4x-2), let's distribute:
12(x+4) + 14(4x-2) = 12x + 48 + 56x - 28
Combining like terms, we have:
12x + 56x + 48 - 28 = 68x + 20
To express the answer in mixed number form, we divide the coefficient of x (which is 68) by the constant term (which is 20). The quotient is 3 and the remainder is 8. Thus, the answer in mixed number form is:
3 + 8/20 = 3 + 2/5
Add: (4d−3)+(12d+4)
To simplify the expression (4d-3) + (12d+4), let's combine like terms:
(4d-3) + (12d+4) = 4d + 12d - 3 + 4
Combining like terms, we have:
4d + 12d - 3 + 4 = 16d + 1
Therefore, the simplified expression is 16d + 1.
