Pest infestations is the infiltration of pests on an area which can be prevented by taking some measures such as taking out of the trash, cleaning of the area regularly with disinfectants, storing the food in a closed and secured place, etc.
What is Pest infestation?
The pest infestation can be defined as the situation when a species which is considered as a 'pest' infiltrates a location or an area, either alone or in a group. This can affect the environment nearby, and the environment itself, and results into an increased risk of health-related problems or damage.

Measurements of the blood of a marathon runner during a marathon race do not show a similar rise in lactic acid levels. Explain fully why this is the case.
Blood measurements of a marathon runner during a marathon race do not show a similar rise in lactic acid levels because he undergoes mostly aerobic respiration.
What are aerobic and anaerobic respiration?Aerobic respiration is respiration which occurs in the presence of oxygen.
Anaerobic respiration is a respiration which occurs in the absence of oxygen
During aerobic respiration in humans, the end-product is acetylcoA while in anaerobic respiration, the end product is lactic acid.
A sprinter undergoes mostly anaerobic respiration and produces lactic acid, while a marathon runner undergoes mostly aerobic respiration and produces less lactic acid.
Therefore, blood measurements of a marathon runner during a marathon race do not show a similar rise in lactic acid levels because he undergoes mostly aerobic respiration.

what type of disorder is sickle cell anemia
It's an "Inherited Blood disorder"
Explanation:
what is "Sickle cell anaemia"?
A group of disorders that cause red blood cells to become misshapen and break down.
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape.
Sickle cell disease is caused by inheriting the sickle cell gene.
The sickle cells die early, which causes a constant shortage of red blood cells. Also, when they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious problems such infection, acute chest syndrome and stroke.
Explanation in brief:
Anemia has three main causes:
blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

4.A
Explanation:
Assume that k and m are two unlinked genes that affect hearing. The dominant k allele is necessary for hearing, and the dominant m allele causes deafness regardless of the other genes present. Given this, what fraction of the offspring of parents with the genotypes kkmm and kkmm will most likely be deaf?.
The percentage that the offspring will be deaf is 75%. Two punnet squares are needed each for km and Kkmm individuals. In punnet square 1, half of the genotypes are Km and km while half are Mm and kk in punnet square 2. The two punnet squares are then combined to form a final one where a quarter of the offspring is deaf.
What does genotype mean?In a wide sense, the word"genotype" refers to the genetic makeup of an organism; it defines an organism's complete set of genes. In a more thin sense, the term can be used to guide the alleles, or variant forms of a gene, that are carried by an organism.

Changes in ecosystems can be attributed to natural causes, such as natural disasters, seasonal variations in climate, currents, and tidal activity. Many of these changes can affect the amount of food resources available in an ecosystem. Research one natural change that currently affects or could affect the aquatic ecosystem you chose. Use your food web model to explain how this change can affect the competition of food resources in your aquatic ecosystem.
The reduction of food sources results in the competition of food resources in the aquatic ecosystem.
How natural disaster can leads to the competition?Severe storm occurs in the water which adversely affected the aquatic ecosystem. This change can affect the competition of food resources in your aquatic ecosystem because the food on which the aquatic animals feed is destroyed by the storm. So less food is available for the organisms which leads to competition between organisms.
So we can conclude that the reduction of food sources results in the competition of food resources in the aquatic ecosystem.

Mary and larry each have free earlobes and dark hair. they are both heterozygous. (e = free earlobes, e = attached earlobes, d = dark hair, d = light hair). e is dominant, e is recessive. d is dominant, d is recessive. what genotypes and phenotypes can their offspring have and what is the probability of each genotype and phenotype?
The genotypes and phenotypes their offsprings can have include only free lobes and attached hair.
What is Genotype?This is defined as the genetic constituent of an organism while phenotype represents the physical characteristics.
Dd and Ee when crossed will give DE, De, dE and de which means that the genotype will be 1 homozygous dominant,2 heterozygous and 1 homozygous recessive for free lobes and attached hair.
The probability = number of favorable outcome/ total number of outcome.

How does global climate change impact coral growth? (4 points)
Global climate change does not impact coral growth.
Climate change decreases the overall temperature of the ocean, preventing coral growth due to the lack of acidic waters.
Greenhouse gases trap solar radiation, which decreases the temperature of the ocean, causing algae to bloom and prevent coral growth.
Greenhouse gases trap solar radiation, which raises the temperature of the oceans, preventing algae growth that is needed for coral growth.
Climate change impacts coral growth through a rise in the temperature of the oceans which limits the growth of algae.
Climate change and coralsClimate change is brought about by a rise in the global temperature as a result of an increase in the concentration of greenhouse gases. The gases trap reflected solar radiation and cause an increase in the temperature of the globe.
An increase in the temperature of the globe also causes an increase in the temperature of the various oceans of the world. Thus, the growth of algae which are the major components of coral reefs is impacted negatively.
