replicate the following dna strand TAT-TAG-ATT-ACA
The replication of the given DNA strand TAT-TAG-ATT-ACA is ATA-ATC-TAA-TGT.
What is DNA replication?DNA replication may be defined as a type of biological process through which the genomic DNA of an organism gets copied into the cell during the time of cell division. During this process, the two identical replicas of DNA are produced from one original DNA molecule.
According to the context of this question, when it comes to DNA replication, adenine is replaced by thymine and vice-versa while guanine is replaced by cytosine and vice-versa. So, the amount of adenine remains equal to the amount of thymine and the amount of guanine remains equal to cytosine.
Therefore, the replication of the given DNA strand TAT-TAG-ATT-ACA is ATA-ATC-TAA-TGT.

There are different forms of energy and one form of energy can be converted into another. When we light a wax candle, the process is highly exothermic and on burning, the chemical energy of the wax gets converted into heat and light. A good source of energy is to be selected for the choice of work to be done. In ancient times, wood was the most common source of heat energy. We, in our daily lives, use various energy sources for doing the work. Nowadays we use diesel and electricity to run trains. We also use fossil fuels in vehicles which has some serious disadvantages, mainly air pollution. The recent example of air pollution was ‘Smog’ in the National Capital Region of Delhi. This pollution was a result of burning ‘Parali’ in northern states of the country, which affected the eyes and also caused serious respiratory problems.

onsider a scenario where a native plant population is growing at it's carrying capacity in a community. The seed of an invasive species is brought in by a squirrel, which then germinates, grows and reproduces resulting in the establishment a population of this invasive plant species. The invasive species has very similar niche as the native plant species. How do you predict the invasive plant population to be affected by the presence of this native species
The given question is incomplete, the complete question is:
Consider a scenario where a native plant population is growing at it's carrying capacity in a community. The seed of an invasive species is brought in by a squirrel, which then germinates, grows and reproduces resulting in the establishment a population of this invasive plant species. The invasive species has very similar niche as the native plant species. How do you predict the native plant population to be affected by the presence of this invasive species?
The invasive species fitness will be limited by the native plant species
The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
There will be no change to the native plant population
The invasive species will grow unchecked and exponentially
No listed answer is correct
Answer:
The correct statement is the fourth one, that is, the invasive species will grow exponentially and unchecked.
Explanation:
The fitness of the invasive species will not get restricted by the native species. Though the opposite takes place as the original niche of the local species does not possess the natural predator for the invasive species. Therefore, invasive species emerge fitter and reproduce exponentially without population control.
The carrying capacity of the native species will not go down before the arrival of the invasive species, however, will go down post its arrival.
As the invasive species has no natural predators, one can witness a substantial reduction in the population of the local plant population. The invasive species will utilize the niche of the local plant, therefore, resulting in the reduction of the native species population, as they have share habitat, food resources, and other natural resources.
It is correct that the invasive species will grow without any control. An outbreak of invasive species generally takes place due to the absence of its natural predators in the ecosystem at the time of its introduction. Hence, the correct statement is the fourth one.
Invasive species establish in a new area, overgrow, and negatively interact with native species. The correct option is 4). The invasive species will grow unchecked and exponentially
-----------------------------------
Let us firts reviw some framework.
When talking about dispersion, we refer to the change in a species' range or distribution area.
When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their
• reproductive rate,
• population growth, and
• interaction with native species.
The introduction of invasive species has ecological, economic, socio-cultural consequences.
Once an invasive species has been established, it overgrows.
In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.
These factors favor their establishment because they are adapted to surviving under harder conditions.
They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.
They can also become significant predators of native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.
They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.
They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
As they expand, they can also affect human in an economic manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.
According to this information, we can answer the question.
We need to predict how NATIVE species are affected by INVASIVE species.
The options are,
1) The invasive species fitness will be limited by the native plant species
When talking about invasive species, this is not an option. Invasive species always affect the fitness of native species. So this option is not correct.
2) The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
The carrying capacity will still be the same. But resources availability will decrease faster because both species have the same requirements. They compete for the same resources. This option is not correct.
3) There will be no change to the native plant population
The will occur changes for the native population for sure. It will be affected by the presence of invasive species. So this option is not correct.
4) The invasive species will grow unchecked and exponentially
Invasive species population will express an uncontrol exponential growth during its establishment phase.
This plant species find the perfect conditions to reproduce and increase its population size.
It finds available space, no predators, water and nutrients availability, proper light exposure, among others.
They can successfully compete with native species, displacing them and getting more space.
THIS IS THE CORRECT OPTION
5) No listed answer is correct
Not correct

Use the ideas of natural selection to suggest how woolly mammoths may have developed..
Science !!
PICTURE BELOW
Answer:
thats crazyyyy
Explanation:
Woolly mammoths developed thick fur and large ears to survive in cold climates through natural selection.
The cold climate of the Pleistocene epoch favored the survival of animals that were well-adapted to cold weather. Woolly mammoths had thick coats of fur that helped to keep them warm, and they also had large ears that helped to dissipate heat. Woolly mammoths had a long trunk.
The trunk of the woolly mammoth was used for a variety of purposes, including gathering food, drinking water, and communicating with other mammoths. The trunk was also a valuable tool for helping the mammoth to survive in cold weather.
For example, the mammoth could use its trunk to blow snow away from its food or to reach food that was buried under the snow. Woolly mammoths were social animals. Woolly mammoths lived in herds, which helped them to survive in cold weather. The herds provided protection from predators and helped to keep the mammoths warm.

gene flow
natural selection
gene mutation
genetic drift
Answer:
C (Gene Mutation)
Explanation:
Edge. 2020
Genetic mutation is most likely to cause differences in the population. Therefore, option "C" is correct.
What is a genetic mutation?A prominent change in the sequence of the DNA is known as a genetic mutation. Mutation can be useful and nonsense. Mutation can alter the function of the DNA gene. To understand the genetic mutations, the sequence of the DNA should be known.
The types of genetic mutations are frameshift mutation, insertion and deletion mutation, translocation mutation, and substitution mutation. Albinism can be genetically transferred to the offspring. Both parents should carry the gene responsible for the albinism in oculocutaneous albinism.
Therefore, Albinism occurs when both parents contribute homozygous genes to offspring.
