A gene with the sequence ATTCATTCA underwent duplication after a few generations. Which sequence represents this gene after the mutation?
Answer:
The sequence would be ATTCATTCA.
Explanation:
Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.
So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out. Trust me, it's a great video, it's much better than my explanation.
A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type
of limiting factor causes this?
O density dependent
O density independent
O population dependent
O population independent
Answer:
Density independent is the correct answer
The type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.
What are density-independent factors?Density-independent factors are environmental factors that affect populations regardless of their size or density. These factors can include natural disasters such as forest fires, floods, hurricanes, droughts, and other extreme weather events. Other examples of density-independent factors include habitat destruction, pollution, and climate change. In the scenario described, a forest fire destroyed an area, which can lead to the decline of both tree and bird populations. The fire could kill the trees and destroy their habitats, making it difficult for the surviving trees to grow or reproduce.
Hence, the type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.

Which of the following most accurately describes most scientists' current understanding of the evolution of humans?
A: Humans have not evolved.
B: Humans, chimpanzees, and other primates share a common ancestor.
C: Gorillas evolved from humans and chimpanzees.
D. Humans evolved from gorillas and other primates.
Answer:
B: Humans, chimpanzees, and other primates share a common ancestor.
Explanation:
According to the theory of evolution, organisms of a particular species change in their characteristics over several generations because of the process of natural selection. The idea of evolution derives from the fact that all species are related and gradually change over time.
Species which are somewhat related all share a common ancestor. Hence, humans, chimpanzees, and other primates all share a common ancestor.

An astronomer measures the distance to two stars using the parallax method. When comparing the placement of the stars six months apart, the star that is further away: A. Changes position the most B. Changes position the least C. Appears brighter D. Appears dimmer
Answer:
I would say A but im not 100% sure
Explanation:
The parallax method uses the angle to measure the distance of the objects in space. When the method is used 6 months after then, the star further away changes its position the most. Thus, option A is correct.
What is the parallax technique?The parallax method determines the displacement of the object in the space when viewed from the line of sight and is determined by the angle of the inclination of the shift.
It is used to measure the distance of the planet to the nearby stars and is measured again after six months. It is the change of the position of the object or the celestial body with respect to the observer's position.
Therefore, the star located farthest will change its position the most.

Advocates for organic farming claim that their methods result in a number of benefits to farmers, consumers, and the environment. Scientists now plan to study the claims that organic farming advocates make by developing testable hypotheses about the economic and environmental benefits of growing organic foods. The scientists plan to collect data from farmers and other producers. Which hypothesis should the scientists use
Answer:
''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.''
Explanation:
The hypothesis i.e. ''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.'' This hypothesis can be tested by the scientists by taking two fields in different location having same environmental conditions. One field they apply conventional farming whereas other field apply only organic materials and no chemicals. We can see that the cost on expensive fertilizers, pesticides and weedicides can't used in organic farming so it is economically benefitted to the farmers as well as no pollution occurs which happens due to the use of chemicals. Moreover, the price of organic food is 3 times higher due to its non-hazardous nature.
