How do genetics play a role in evolution?
A few of these characteristics are favourable and are called as beneficial mutations which provide a better survival benefit to changing surroundings. Evolution of a new class of species altogether occurs when a permanent change takes place in the phenotype of an entity as a result of natural selection and competition when an environment continues to stay for longer durations incorporating better-adapted entities.
Gene mutations cause the evolution we observe. It causes a change either in the organization or amount of genetic material in a cell. Such a mutation if occurred in a gamete can be easily inherited by the emerging gamete. New alleles of genes are produced as a result of mutations and hence the variations between entities. Therefore, genes and genetic mutations play a significant role in the process of evolution.
Why are senses necessary for behavior?
Answer: Senses are necessary for behavior because behavior is a response to an organism's environment. Without senses, the organism would be unable to sense anything in the environment to react to. Senses tell an organism what to avoid and what to interact with; they guide the organism's decisions. Even organisms with very simple senses have some way to detect changes in the environment that need to be reacted to.

Select the correct answer. Plants, through the process of photosynthesis, use solar energy to produce the end product glucose. Since energy is used here, what type of reaction is photosynthesis? A. Endergonic reaction B. Exergonic reaction C. Reversible reaction
Since energy is used, the type of reaction photosynthesis is : ( A ) Endergonic reaction
What is Endergonic reaction ?Endergonic reaction is a type of reaction that requires a free energy to continue, since photosynthetic organisms such as green algae require the use of free energy ( solar photons ) to reduce CO₂ and oxidation of H₂O to oxygen.
Therefore we can conclude that photosynthesis is an example of an endergonic reaction.

Which prediction most likely describes the location of two of the three cities?
Which prediction most likely describes the location of two of the three cities?
a. City 1 is north of city 3.
b. City 2 is north of city 3.
c. City 3 is north of city 1.
d. City 3 is south of city 2.
Answer:
C. City 3 is north of City 1
Explanation:
City 3 shows cooler temperatures than City 1 throughout the year. This is consistent with North American cities found at northern lattitudes compared to those found further south. Compare Milwaukee, WI (north) with Miami, FL (south).
Gas Exchange and Transport Oxygen and carbon dioxide are exchanged across the walls of alveoli and capillaries. Chemical properties of blood and red blood cells allow for efficient transport of gases throughout the body.Carbon dioxide and oxygen are exchanged across capillary and alveolus walls.Hemoglobin binds with and transports oxygen that diffuses from alveoli to capillaries. It also increases the efficiency of gas exchange.Carbon dioxide is transported in the blood in three ways. Most combines with water and forms carbonic acid. Some dissolves in plasma. Some binds to hemoglobin and proteins in plasma.
For Questions 2-7, complete each statement by writing the correct word or words.
3. The gases exchanged in the lungs are carbon dioxide and__________.
The function of the respiratory system is to move two gases: oxygen and carbon dioxide. Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them
If t=talk and t= short what will be the physical appearance of the offspring in the cross
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).

Wind turbines use blades that spin a
generator which generates electricity.
Answer:
Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.
Burning fossil fuels involves releasing carbon dioxide and other greenhouse gases into the atmosphere at a rate that is much faster than the carbon cycle can remove it.
Is the previous statement true or false?
Answer:
true
Explanation:
because the energy that comes from burning fossil fuels is converted into electricity and heat in power plants. When fossils are burned, carbon and hydrogen react with oxygen to produce carbon dioxide (CO2) and water (H2O) during this reaction heat is produced
