It is only 10% efficient because the majority of the energy is converted. Some is lost in heat, some is not processed at all. Mostly a lot of energy is used to regenerate ATP.

Explanation:

This rapid population growth has an adverse effect on the natural resources and quality of life.

However, overpopulation has a deleterious effect on the environment due to the current lifestyle.

There would be rampant exploitation of natural resources, excess human waste accumulation, chances of epidemics, etc.

Besides, it would also lead to socio-economic problems like poverty, malnutrition, violence, corruption, etc.

Human overpopulation occurs if the number of people in a group exceeds the carrying capacity of the region occupied by that group.

DNA replication is Group of answer choices conservative. a one-step process. semi-conservative. not carried out by enzymes. not
Alex787 [66]

Answer:

The correct answer is: semi-conservative.

Explanation:

DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.

DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.

DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).

DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.

What are the two factors that define our traits?
coldgirl [10]

There are a few theories as to what defines our traits to create our personality

According to one such theory, Dan P. McAdams claims our personalities develop in <span>three </span>stages:

<span>Our genes cause genetic mutations forming a 'draft' personality.During our early upbringing, our parents, teachers and friends treat us differently based on our looks and draft personality.Once we are older we then form a narrative of our lives based on our experiences growing up, and make decisions consistent with the character we have created.</span>

So our traits started from slight genetic variances, which effected how we were treated, which then shapes our own self-narrative. So really, our personality is one big story that we tell ourselves, and our childhood was the prologue to that story.
