i think im not sure

umm im trying to figure it out tho i think its A

Explanation:

Answer:

AUG GGU UCA

Explanation:

To transcribe the sequence, we first must find the complementary sequence of the DNA sequence. To do this, we must know that "A" pairs with "T", and "G" pairs with "C". What this means is we replace A with T,G with C, and vice versa. We get ATG GGT TCA. Now all we have to do is replace all the "T"'s with U's as Thymine is replaced by Uracil in RNA. Doing this we get AUG GGU UCA, which is the answer.

d. The ways in which universal patterns of behavior and cognitive processes have evolved over time

Answers

Answer:

I believe the answer is D. The ways in which universal patterns or behavior and cognitive processes have evolved over time.

The primary focus of evolutionary psychology is the ways in which universal patterns of behavior and cognitive processes have evolved over time. The correct option is D.

What is evolutionary psychology?

Evolutionary psychology is the study of behavior, thought, and emotion through the evolutionary biology lens.

According to evolutionary psychologists, all human behaviors are influenced by physical and psychological predispositions that helped human ancestors survive and reproduce.

Evolutionary psychologists believe that the human brain evolved in response to specific problems that early humans faced.

One central tenet of evolutionary psychology is that understanding modern human behavior requires considering the environment in which early humans evolved.

The study of how universal patterns of behavior and cognitive processes have evolved over time is the focus of evolutionary psychology.

Variations in cognition and behavior would affect an individual's ability to reproduce and pass on those genes to their offspring.

Thus, the correct option is D.

Which of the following is a correct DIFFERENCE between sexual and asexual reproduction?

A. Sexual Reproduction creates genetically different offspring.

B. Sexual Reproduction creates genetically identical offspring.

C. Asexual Reproduction creates genetically different offspring.

D. Asexual Reproduction creates no offspring.

Answers

Answer:

A. Sexual Reproduction creates genetically different offspring.

Explanation:

Sexual Reproduction is created through 2 different opposite parties, in which the product takes around half of the genes from each individual parties. The traits that are shown are then decided on whether or not they are dominant or recessive or non-existent.

In a Asexual Reproduction, the reproductive capabilities of both parties are found inside one organism. The organism is able to produce both the sperm and egg, and therefore do not need a partner to reproduce. This means that the DNA inside the body is the only source for production, and that there will be very little variation in the DNA.

~

Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique
