The correct answer is D. According to DNA comparisons, humans share a common ancestor with chimpanzees.
Explanation
A scientific statement is a statement made based on scientific evidence, that is, a scientific statement is the result of several tests focused on testing a hypothesis or proposal. These scientific statements can be developed in different areas of knowledge such as science, biology, physics, mathematics, geometry, among others. they are also predominant in the exact sciences because in the human sciences it is complicated to establish scientific statements because human behavior does not obey exact laws. According to this definition, option D. is the correct answer because it refers to DNA tests between humans and chimpanzees and therefore this is based on scientific evidence and tests.
Hi, I hope this helps you!
All diploid adults inherit half of their DNA from each parent. When they are ready to reproduce, diploid reproductive cells undergo meiosis and produce haploid gametes. These gametes then fuse through fertilization and produce a diploid zygote, which immediately enters G1 of the cell cycle.
Also, Organisms with a diploid life cycle spend the majority of their lives as diploid adults. When they are ready to reproduce, they undergo meiosis and produce haploid gametes. Gametes then unite in fertilization and form a diploid zygote, which immediately enters G1 of the cell cycle. Next, the zygote's DNA is replicated.
Answer:
a) The enhancer site is a distal control site many nucleotides upstream from the promoter site, and activates the initiation complex of transcription.
Explanation:
Enhancers are the regulatory DNA sequences that are generally located quite away from the coding regions of a gene. These sequences are mostly present upstream of promoter sequences. Enhancers regulate the gene expression by stimulating the formation of an active transcription initiation complex and thereby, increase the rate of RNA synthesis. Enhancers also serve as the binding site for specific regulatory proteins. These proteins bound to the enhancers then activate transcription by interacting with the proteins bound to the promoters.
"Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid. The matched pairs of chromosomes in a diploid organism are called homologous chromosomes."
Producers (plants) are important to our ecosystem because they are the base of life. If it wasn't for producers, you wouldn't be eating your salad while your reading this answer. That chicken you had yesterday wouldn't be there if it wasn't for corn (a producer).
