Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Describe how this process has played out in the maintenance of the sickle-cell trait. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today
Answer:
Adult humans capable of digesting lactose were selected, thereby this phenotypic trait became common in dairy consuming societies
Explanation:
From the first moment after birth, babies can digest lactose in milk because they produce lactase, which is an enzyme capable of hydrolyzing lactose into glucose and galactose. In human societies that non consume milk products, the level of the lactase enzyme abruptly decreases during the first years of life due to the inactivation of the gene encoding this enzyme (i.e., lactase gene). However, in dairy consuming societies, a genetic mutation in the lactase gene that appeared among early cattle-raising people in Europe was selected, nowadays, this mutation is mostly present (i.e., in a higher frequency) in these societies, thereby adult people is generally adapted to consume lactose-based products.

What is trail?Researchers gather information, group volunteers according to broad characteristics, and compare changes over time.
Repeated trials are when researchers do a measurement multiple times - at least three, commonly five, but the more the better. When they measure something once, the chance that the number he get is accurate is much lower. But if researcher measure it several times, then he can take an average of those numbers and get a result that is much closer to the truth.

How do was the carbon cycle most different before 1900s
Answer:
I would probably say that it was most different because of the cars. The first car was released in 1885, but they weren't really popularized in America until the 1920s. So therefore, Earth's atmosphere was much better than it is now.

so e.coli have mitochondria and undergo cellular respiration?
Answer:
No
Explanation:
E. coli are prokaryotes, meaning they do not have membrane-bound organelles like mitochondria.
However, they do perform respiration to produce the energy needed for cellular processes. They can perform both aerobic respiration (in the presence of oxygen) and anaerobic respiration (in the absence of oxygen).
Since they don't have any membrane-bound organelles, these processes take place in the cytoplasm

A biology student looked through a microscope and observed an Elodea cell in a drop of water and illustrated it in diagram A. He added a 10% hypertonic salt solution to the slide. He then observed the cell and illustrated the change in diagram B. What caused the change in the appearance of the cell after the salt solution was added?
More water flowed into the cell than out of the cell.
More salt flowed into the cell than out of the cell.
Lass salt flowed into the cell than out of the cell.
More water flowed out of the cell than into the cell.
Answer:
There are no diagrams in this question, however, it can be answered.
More water flowed out of the cell than into the cell.
Explanation:
According to this question, a biology student added 10% hypertonic salt solution to an Elodea cell in a drop of water. The student illustrated the changes observed in diagrams A and B. Based on the principles of OSMOSIS, which is the movement of water from a region of lower solute concentration to a region of higher solute concentration, water will flow out of the cell.
Since the solution outside the Elodea cell has more solute solute/salt concentration, water will be move down the concentration gradient from the cell into the extracellular solution. Hence, more water flowed out of the cell than into the cell.

What is cell?Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.

Why does a gummy bear soaked with water shrink after being soaked with salt water?
Answer: Because they were placed in a hypertonic solution, there was a natural tendency for water to leave the gummy to create an isotonic solution. The greater amount of salt in the salt water solution would cause more water to leave the gummy. Therefore, the gummy would shrink more in a higher concentration of salt water
Explanation:
The gummy bear shrinks after being soaked with salt water because the gummy bear loses water to the environment.
OSMOSIS:
Osmosis is the process whereby water moves from a region of higher concentration to a region of lower concentration through a semipermeable membrane. The salt water in this question represents a hypertonic solution that contains high salt conc. but low water concentration. This means that if the gummy bear is placed in a salt water, water will move from the cells of the gummy bear (low concentration of salt) to its environment (high salt concentration) based on osmotic principle. Therefore, gummy bear shrinks after being soaked with salt water because the gummy bear loses water to the environment.Learn more at: https://brainly.com/question/19803174?referrer=searchResults
