Answer:A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. ... The wings force the air downward and that pushes the plane upward.

The sequence of dna from your snork is found in which organelle?

Leto [7]

Explanation:

The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

2. How has genetics, combined with paleontology, added to our understanding of evolution?

motikmotik

Answer:

To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.

Explanation:

Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
By using these techniques, biologist have found that homo sapiens are 99% have their similarities with chimpanzee
Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.
