Answer:
It transport oxygen from lungs to the cells.
Explanation:
The presence of iron in our body is very important for this process because iron is responsible for the transportation of oxygen. Hemoglobin is made up of iron that takes oxygen from the lungs to each and every cell. Iron is an essential element for the formation of blood in human body. About 70 percent of body's iron is found in the red blood cells of our blood called hemoglobin and in the muscle cells called myoglobin. So we can say that iron is very important for the release of energy in the process of respiration.

Explanation: trust
Birth and immigration rate is greater than death and emigration rate. Therefore, option (C) is correct.
What is exponential growth?Exponential growth is a type of population growth pattern in which a population size increases at an accelerating rate, with each generation or time period adding a larger number of individuals than the one before it. This type of growth results in a population having a higher total number of members than it did in the previous generation.
To put it another way, the rate of population growth picks up steam over the course of time, producing a J-shaped curve when the data is plotted on a graph. This pattern can emerge when there is an abundance of resources available to a population but only a moderate amount of competition for those resources. This results in rapid reproduction and population growth as a result.

How will restoring land to its original state after mining affect the final price of the mined resource?
Answer:
The price of the resource is increases.
Explanation:
The restoring of land to its original state after mining greatly affect the final price of the mined resource because the company who sells the mined resource also add the price of restoring of land which increases the price of the mined resource. The restoring of land also needs money and this money is paid by the company who did mining in that region so the company also add the amount of restoring of land when it sells its product or resource.

In Marker Analysis, how are STRs related to alleles? Be sure to define each term (STR and allele) and explain how the two result in different band patterns when run in gel electrophroresis.
Answer:
The number of STR repeats is unique and therefore it is considered as an allele of that locus
Explanation:
Short Tandem Repeats (STRs), also known as microsatellites or simple sequence repeats (SSRs), are short DNA sequences with a size of 1-6 nucleotide bases which may be many times repeated in tandem. STRs localize in specific regions of the genome (loci) and therefore they are molecular markers. Gel electrophoresis a technique used to separate DNA fragments based on their size. In consequence, the pattern of STR repeats or 'alleles' obtained by electrophoresis can be used to identify individuals. In a gel electrophoresis, STR markers produce different bands that run more slowly or faster on the gel in different lanes according to their size (e.g., more slowly >> higher size of the STR sequence), and thereby STR alleles are unique and serve to identify individuals.

How does actin and myosin work together to help you lift an object?
Answer:
Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another.
Actin and myosin work together to help you lift an object in the following way:
Muscles are tissues of the musculoskeletal system that have the function of generating a force towards the bones with the ultimate goal of performing a movement.In order for this function to be carried out correctly, it needs proteins that are found inside the muscle fiber, these proteins are myosin and actin.The myosin head in the presence of ATP binds with the actin filaments, in order to generate a minimum slip that later becomes a coordinated and precise movement as lift an object.That is, myosin binds to the actin protein to generate the contraction of the muscles, and therefore the movements we make with our extremities.Therefore, we can conclude that actin is a cellular protein in muscles that is involved in muscle contraction when it connects with myosin.
