Hi, thank you for posting your question here at Brainly.
Chromatin contains proteins and DNA. The cellular division processes, mitosis and meiosis, condenses the chromatin to form chromosomes. They divide into two cells (mitosis), then two 4 cells (meiosis). The chromosomes contain the gene.
Answer:
The correct answer is - microevolution.
Explanation:
Microevolution is the very small evolutionary change specially allele frequencies on the level of species that occurs slowly over period of time. These changes occurs on the level of DNA or genetic level.
These evolution can be caused by the natural selection process or genetic drift over the generation of the species or population over period of the time. It is the study of the evolution that occurred on level of separated gene pool.
Thus, the correct answer is- microevolution.
In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy.
This relates to the speed at which an object should travel to "break" free of any gravitational pull.
Venus: 10.46 km/s
Mars: 5.027 km/s
Answer: DD and Dd
Why? Dimples are dominant meaning that if one dimple trait is in allele it will be shown even if there is a recessive trait. So DD and Dd are the answers
Answer:
food molecules become digested once there is a concentration gradient to drive diffusion, the nutrients need a path across the membrane. fats and fat soluble nutrients can move directly across the lipid membrane. water, gasses ane other very small molecules can diffuse through the pores of the cell.
