Answer:
atural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

Describe how the force of gravity acts upon an object, and give an example. btw this is 5th grade i just copied and paste what my teacher said lol please help
Explanation:
Gravitational force or force of gravity is the weakest force in the universe. It is a non contact force and is always attractive in nature.
Force of gravity always acts in the downward direction.
It is denoted by letter g.
examples of force of gravity are as follows :-
When a ball is thrown from the top of a roof it always goes downwards due force of gravity.When a ball is suspended with an inextensible string the ball's weight act download direction due to the formula of W = mg.The force that causes a car to coast downhill even when you aren't stepping on the gas.The force that causes a glass you drop to fall to the floor.The force that holds the gases in the sun.hope this helps you.

Which example best illustrates flower-pollinator coevolution?
A. Bees carry pollen grains from flower to flower.
B. Hummingbirds use long beaks to collect nectar from tubular flower
C. Butterflies rest on pale-colored flowers.
D. Ants eat flower nectar and occasionally get pollen stuck to their bodies.
Answer:
a or b I think its A tho
Explanation:
The best example iillustrates flower pollinated coevolution is Bees carry pollen grains from flower to flower.
What is coevolution in flower?Coevolution is the term used to describe the mutually reliant evolution of at least two species. Since its initial description in relation to insects and flowering plants, coevolution has been used to explain fundamental evolutionary processes like sexual reproduction, contagious diseases, and ecological communities.
Coevolution works by exerting reciprocal selective pressure on two or more species, similar to an arms race where competitors try to outdo one another. Predator-prey, host-parasite, and other competitive relationships between organisms are classic examples.
Even though coevolution often only involves two species, it can occasionally involve more. Coevolution also produces modifications that are advantageous to both parties.
Therefore, The best example iillustrates flower pollinated coevolution is Bees carry pollen grains from flower to flower.

Flies are scavengers and tend to break down dead organisms. Based on this information, what is a plant characteristic that would best attract flies?(1 point) flowers that are brightly colored flowers that are brightly colored flowers that emit a rotten odor flowers that emit a rotten odor flowers that are light colored flowers that are light colored flowers that emit a sweet odor
Scavengers are the organisms who feeds upon the dead organisms. The flowers which emit rotten odor attract most of the scavengers. Thus, the correct option is B.
What are Scavengers?A scavenger is an organism that mostly consumes the decaying biomass, such as meat or rotting plant material in an ecosystem. Many scavengers are a type of carnivore. A carnivore is an organism that eats meat.
Vultures are the best example of scavengers. Other examples of scavengers include Coyote, Striped Hyena, Jackals, Bottle flies, Ants, Beetles, etc.
Scavengers and decomposers feed on dead materials and break them down into chemical parts. Nitrogen, carbon and other nutrients can then be used again by plants and animals. Without decomposers and scavengers, the world would be covered with dead plants and animals. As the dead organisms cannot be decomposed.
Therefore, the correct option is B.
