Outline the effect of the following mutations:
TAG-> TAT
TAC-> TCC
Answer:
TAG-> TAT >> sense mutation
TAC-> TCC >> missense mutation
Explanation:
A sense mutation is a type of mutation that changes a stop codon into a sense codon, thus producing an elongated protein. The TAG codon (UAG in the RNA) is a stop codon, while TAT (UAU) encodes for tyrosine, thereby TAG-> TAT is a sense mutation. On the other hand, a missense mutation is a type of point mutation where a single nucleotide change generates a new codon which encodes a different amino acid. In this case, the TAC codon (UAC) encodes for tyrosine, while TCC (UCC) codon encodes for serine, and therefore TAC-> TCC is a missense mutation (Tyr to Ser mutation).

Explanation:
Natural selection will only lead to evolution if it allows for an organism to ________.
a. possess advantageous traits.
b. compete for resources.
c. produce offspring.
d. all of the above.
Answer:
b
Explanation:
Natural selection will only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.
What is natural selection?Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.
Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.
Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,
Represent a struggle for survival.Exhibit variation.Undergo inheritance.These are the conditions that are said to be both necessary and sufficient for natural selection.
Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.
Thus, the correct option is d.

The genetic researchers at Bay Medical Company are interested in spiders with the trait for medium silk flexibility. They
think this sik can be used for medical purposes such as for making stitches and for creating artificial tendons. Why do
you think offspring B has the medium silk flexibility trait?
Answer:
Due to similar shape.
Explanation:
I think offspring B has the medium silk flexibility trait because this offspring B is identical to the spider that is responsible for medium silk flexibility trait. There are some offspring identical to male parent spider due to the presence of dominant allele whereas very littles number of offspring is similar in appearance with the female spider due to recessive allele. If the male spider has medium silk flexibility trait so more number of offspring has medium silk flexibility trait as compared to others.
The people at the Medical research bay company are researching on spiders. the trait for the medium silk flexibility. The silk can be used for medical purposes and creating other tendons.
The B offspring has the medium flexibility trait it's identical to the spider that is responsible for the medium silk flexibility trait. There are some offspring identical to male parent spider due to the presence of dominant allele spider due to recessive allele.Learn more about the medical Company are interested in spiders.

Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?
Answer:
The correct answer is - as energy lost at every trophic level.
Explanation:
In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.
The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.
As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.
In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.
Thus the response above is right.

The following pieces of evidence does not mid-ocean ridges are formed Mid-ocean ridges are found on the bottom of most oceans.
What is mid-ocean ridges?The central parts of the oceans have mid-ocean ridges. The mid-ocean ridges are volcanic underwater mountain ranges.
There is constant propelling of magma, and as the magma cools off quickly it creates new crust.
This results in the mid-ocean ridges gaining heights of up to 1.5 km above the surrounding area.

Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

Answer:
Climate.
Explanation:
Climate is the factor which is responsible for the decreasing the availability of crops because climate is the factor that allows crops to grow in the region. Suitable climatic conditions allows us to grow more plants in the region while on the other hand, less or no crops can be cultivated in the harsh climatic conditions. The plants in the harsh climatic condition are unable to grow such as desert where the temperature is very high and no rainfall occurs to support growing of crops.

17. Explain how carbon reservoirs can
be accessed without the influence
of humans.
Answer:Without human interference, the carbon in fossil fuels would leak slowly into the atmosphere through volcanic activity over millions of years in the slow carbon cycle. ... About half of these emissions are removed by the fast carbon cycle each year, the rest remain in the atmosphere.
Explanation:Hope this helps you!
In the slow carbon cycle, volcanic activity would release fossil fuel carbon into the atmosphere over millions of years without human intervention. The rapid carbon cycle removes half of these emissions annually, leaving the rest in the atmosphere.
What are 4 carbon reservoirs?
These are the reservoirs or sinks that carbon moves through as it cycles through the environment. Carbon is returned to the atmosphere through a wide number of different processes, including the decomposition of organisms, the eruption of volcanoes and fires, the combustion of fossil fuels, and more.
Carbon reservoirs contain substantial quantities of carbon between processes.
Burning fossil fuels such as natural gas, coal, and oil releases CO2, which is damaging to the environment and to individuals.Therefore, the carbon stocks such as fossil fuels have been used by humanity.
