C. Birth and immigration rate is greater than death and emigration rate.
D. Birth and immigration rate is equal to death and emigration rate.
Answer:
A. Birth and immigration rate is greater than death and emigration rate.
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.

The cod fish population has dropped in New England between 1982 until today. How
many times larger was the cod fish population in 1982 as compared to today?
0 it was 27x higher in 1982
it was 19x larger in 1982
it was 95x higher in 1982
0 it was 5x higher in 1982
Answer:
it was 27x larger in 1982
Explanation:
The cod fish population has dropped in New England between 1982 until today due to higher mortality rate. The population of cod fish in1982 is 80000 metric ton of spawning stock biomass while on the other hand, the population of cod fish in 2011 is 2500 metric ton of spawning stock biomass. This lowering of cod fish population is due to higher mortality rate so we can say that the population of cod fish was 27x larger in 1982.

Use your prior knowledge of natural selection to make a prediction about how resource consumption might affect biodiversity (different plants and animals) on Earth. Keep
IN YOUR OWN WORDS I WILL GIVE BRAINYLIST WHOEVER ANSWERS THIS CORRECTLY!!!
Answer:
The wildlife habitat will be changed and poison the wild animals.
Explanation:
The resource consumption greatly affect biodiversity of different plants and animals on Earth because resources helps the organisms to survive. Organisms used resources such as food, space and water etc for growth and survival. If these resources are used up by humans so the biodiversity is negatively affected and the wildlife habitat is converted into agricultural and urban land. The biodiversity is also affected due to production of waste that cause pollution and poison wildlife.
5. Why are fingerprints stronger individual evidence than nDNA?
Compared to fingerprint evidence alone, DNA was far more likely to lead to suspects and result in arrests. In crime scenes where biological evidence was collected and tested, DNA evidence was five times more likely than fingerprints to yield a suspect and nine times more likely to lead to an arrest.
Choose ALL options that refer to the proteins that work together to make a muscle contract. A) fascicle B)actin C)mysoin D)fiber
brainlest and 100 points
Answer:
The troponins involved in muscular contraction are actually a complex of three proteins known as troponin I, troponin C, and troponin T (Figure 2.125). They associate with each other and with tropomyosin on actin filaments to help regulate the process of muscular contraction.MExplanation:
Answer:
mysoin and actin
Explanation:
muscle contractions results from the reaction of myotin and acting.
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.

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.

The answer is D bc looking is destroying the owls home that answer is not c bc this has nothing to do with the owl
In parts of the northwestern United States, logging is destroying many of the forests that are home to the spotted owl, the following is the primary threat to the spotted owl population: loss of habitat that is in option D.
What is the significance of the loss of habitat?The destruction or degradation of a natural environment in which a specific species of animal or plant lives, as a result of deforestation, urbanization, industrialization, and other factors, is referred to as habitat loss. As a result of the loss of habitat the plants and animals that live there are forced to adapt to the new conditions as a result of habitat loss.
