Answer:
D. taking a cool shower
Explanation:
Taking a cool shower may not be a method through which the human body regulates homeostasis.
Homeostasis refers to the maintenance of relatively constant internal body processes. Homeostasis happens naturally in the body system.
A change in the flow of blood to the skin may happen in response to a breach to the normal body temperature. Increased blood flow happens in response to high body temperature and decreased flow happens in response to low temperature.
Shivering of the body happens in response to a drop in the normal body temperature. The shivering helps generate more heat for the body.
Sweating happens in response to excessive body temperature. The evaporation of the sweat causes cooling, thereby returning the body to its normal temperature.

Answer:complementary
Explanation:
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.

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.
A sudden increase in the amount
of available nutrients can create

ecosystem. How?
A. Large numbers of producers can confuse
herbivores.
B. Increased nutrients can cause producers to
compete aggressively with one another.
C. There is not enough oxygen in the
atmosphere to support excessive numbers of
aquatic plants.
Answer:
C
Explanation:
There would be a high amount of nitrates and phosphates, which reduces the amoubt of oxygeb in the tank, that will lead to the difficulty of supportibg the excessive amount of aquatic plants.
Answer:
C. There is not enough oxygen in the
atmosphere to support excessive numbers of
aquatic plants.
Explanation:
n excess amounts, both nutrients can cause an increase in aquatic plant growth and algae blooms, called eutrophication. These algae blooms live at the water surface, in order to easily access oxygen and sunlight. As a result, eutrophication prevents lower water levels from access to sunlight and oxygen in the air.
A primitive eukaryote was discovered that displayed a unique nucleic acid as its genetic material. Analysis provided the following information: (a) The general X-ray diffraction pattern is similar to that of DNA but with somewhat different dimensions and more irregularity. (b) A major hyperchromic shift is evident upon heating and monitoring UV absorption at 260 nm. (c) Base-composition analysis reveals four bases in the following proportions. Note that xanthine and hypoxanthine are both purines. (d) About 75 percent of the sugars are deoxyribose, while 25 percent are ribose. Part A Based on these findings, which characteristics does this unique nucleic acid have
Answer:
c and d
Explanation:
(C) Even though this option seem incomplete, the information revealed also shows it's unique.
One characteristic this nucleic acid has that is different from other nucleic acid is the purines. The purines in both DNA and RNA are adenine and guanine while this nucleic acid has xanthine and hypoxanthine which are the found in the tissues and fluids of other organisms.
(d) Also, it's nucleotide has a mixture of two types of ribose sugars which is unusual because a DNA molecule has deoxyribose sugar while a RNA molecule has a ribose sugar - none of the two nucleic acids have a mixture of both types of sugar.

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

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
What organelle would you not find in a plant cell? Chloroplasts,centrioles,central vacuole,or cell wall?
Answer:
Centrioles
Explanation:
If we look at ths other options Chloroplast and Cell Wall are both needed for a plant to survive and function. So we automatically know that it's going to be there so those aren't an option. We know that both animal and plant cells have a vacuole but plant cells have larger ones so we know that's not an answer. Leaving us with the only other possible answer left, Centrioles.
Answer:
Hey!
Your answer is CENTRIOLES
Explanation:
We know that Plants have a CELL WALL (shape), a CENTRAL VACUOLE (water storage etc) and CHLOROPLASTS (photosynthesis)
BUT Centrioles don't form parts of the "components" of the plant cell...

Use the internet to research genes and their affects on heredity. How many chromosomes do we inherit from each parent? What are recessive and dominant genes? What are inherited traits? What are acquired traits?
Answer:
23 chromosomes
A dominant gene is a type of gene which dominates in the inheritance pattern and masks the other one, on the other hand, a recessive gene is that which does not show its trait in inheritance pattern and hidden by the dominant one. A dominant gene is stronger gene while the recessive gene is a week gene. Dominant gene is always expressed in the upper case letters like A, F, V whereas recessive gene is always denoted by the lower case letters like a, f and v. dominant gene show in the inheritance when one of the two genes is dominant but in case of recessive gene both the genes of a trait should be recessive.
Traits you get from your parents. Inherited features evolve due to genetic material rearrangement and mutation. The parents transfer those traits (inherited) to their offspring. These aren't dying but passed on to the next generation. Example: earlobe attached or free, and curly hair.
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics. They are not passed on to offspring through reproduction.
