Answer:
In many species, females choose the male they will mate with. For their part, males try to be chosen as mates. They show females that they would be a better mate than the other males. To be chosen as a mate, males may perform courtship behaviors. These are special behaviors that help attract a mate. Male courtship behaviors get the attention of females and show off a male’s traits. These behaviors are often observed as direct competition between males. Different species have different courtship behaviors.
Explanation:
B. Decreasing the surface area of solid reactant;
Why? Collision theory suggests that the more opportunities for reactants to come into contact or "collide" with other reactants, the faster the reaction will take place. Hence, decreasing the surface area will decrease the probability of collisions between reactants thereby decreasing reaction rate.
Answer: the dam cause no more fertile soil to enter in to farmers land for growing crops hope this helps :)
Explanation: this dam has caused a big change to the lifes of farmers downstream from the dam. Usually when the river flooded once a year before the dam was built. It deposited fertile soil from upstream on its banks downstream. This washed up soil was extremely furtile, and renewed itself every year at in flood season. But now, since the dam was built the annual flood has been stopped. Causing all the farmers downstream to have to use fertilizers to grow their crops, which makes it more expensive.
Answer:
I'm assuming yellow is dominant since they used Y
YY and Yy are both yellow
yy is blue
So Yellow color would have 75% phenotype probability and Blue would have 25%

Photosynthesis is the process by which the plants make their food with the help of sunlight. This food helps the plant to live and grow. The by-products created by photosynthesis are glucose and oxygen. The glucose is used by the plants for growth and oxygen is released in the air. </span>
