For each scenario below, list the body systems involved and their function during the specific activity.
Regulation / Homeostasis
You get too hot or too cold:
Your diaphragm expands and contracts so you can breathe:
Nutrient Absorption
The reactants needed for cellular respiration are taken in and transported to your cells:
Defense from Illness
A pathogen enters your body through a cut:
Defense from Injury
A bunny is running away from a wolf:
Your hand gets too close to a flame:
Reproduction
A woman’s body prepares for a pregnancy:
A woman’s body prepares for a birth:
Answer:
Regulation / Homeostasis you get too hot or too cold:
If you get either too hot or too cold, sensors in the periphery and the brain tell the temperature regulation center of your brain—in a region called the hypothalamus—that your temperature has strayed from its set point.
Your diaphragm expands and contracts so you can breathe:
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
Nutrient Absorption
The reactants needed for cellular respiration are taken in and transported to your cells:
cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells.
Defense from Illness
A pathogen enters your body through a cut:
The skin and mucous membranes act as a physical barrier preventing penetration by microbes. If the skin is cut then the blood produces a clot which seals the wound and prevents microbes from entering.
Defense from Injury
A bunny is running away from a wolf:
Rabbits have keen senses of smell, sight and hearing, which help them defend themselves from danger. When they sense a nearby predator, they innately freeze in place to camouflage with the landscape.
Your hand gets too close to a flame:
Skin is difficult to ignite, and usually chars in the presence of heat. It takes up to 10 minutes of direct flame for skin to crack open and start leaking out rendered fat. Even if a horse's body started to leak fat, it would be unlikely to go up in flames on its own.
Reproduction
A woman’s body prepares for a pregnancy:
Every month, usually one egg grows within a structure called the egg follicle (a fluid filled sac that nourishes the egg). The follicle produces estrogen, which helps a woman's body prepare for pregnancy by growing a new lining for the uterus.
A woman’s body prepares for a birth:
As your body prepares for birth, your cervix — the muscular ring between your uterus and vagina — begins to soften, dislodging the mucous plug.

Why do you think that some vaccines, such as the flu vaccine, need to be given every year?
Answer:
Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses.
Answer:
Because the virus/sickness would evolve and that vaccine might not protect you.
During a study session about evolution, one of your fellow students remarks "The giraffe stretched its neck while reaching for higher leaves, its offspring inherited longer necks as a result, which statement is most likely to be helpful in correcting this students misconception?
a) characteristics acquired during an organisms life are generally not passed on through genes
b) spontaneous mutations can result in the appearance of new traits
c) only favorable adaptations of survival value
d) disuse of an organ may lead to its eventual disappearance
Answer: Characteristics acquired during an organism's life are generally not passed on through genes.
Explanation:
The most common misconception between students which can be corrected is that the characteristics acquired during an organisms life are generally not passed on through the genes. Thus, the correct option is A.
What are acquired traits?Acquired traits or characteristics are the non-heritable changes in the function or structure of a living organism which is caused after birth and was absent before this. Occurrence of acquired traits could be due to disease, injury, accident, deliberate modification, variation, repeated use, or other environmental influence.
For example, the giraffe stretched its neck while reaching for the higher leaves but her children does not get a long neck by birth however this character has been fixed with time because of the repeated use of the neck for food.
Therefore, the correct option is A.

2. Direct
Explanation:
1. The distance pulled back means you get your answer from the distance pulled back data. Since 50cm is the largest of your given data, that makes the cart go farthest.
2. The farther you pull the band back, the farther the cart will go. Since both increase when you increase the distance you pull the band back, this is a direct relationship.
How can independent assortment help explain genetic diversity in humans? Hint: How many pairs of chromosomes are in a human diploid cell?
Answer:
please give me brainlist and follow
Explanation:
Independent assortment states that all alleles are inherited independently of other alleles. This helps diversity because it helps to further the randomization of traits. If traits were always inherited together, as a "package deal", there would naturally be less diversity than the situation that exists.
How does nondisjunction affect the production of gametes?
Answer:
Nondisjunction Produces Abnormal Gametes. If nondisjunction occurs during anaphase I of meiosis I, this means that at least one pair of homologous chromosomes did not separate. The end result is two cells that have an extra copy of one chromosome and two cells that are missing that chromosome. Click to see full answer.

An eastern screech owl, a carnivore, might compete with which organism most intensely for resources?
A. hawk (secondary consumer)
B. mountain lion (secondary consumer)
C. wren (primary consumer)
D. mouse (primary consumer)
Answer:
The answer is A
Explanation:
Let us take a look at the owl, it is a kind of carnivore, so it must be a secondary consumer(btw, primary consumers are herbivores). So we can eliminate answer C and D. The competition between the same species for this situation is the most intense one, so we can eliminate answer B as well, since hawk and owl are all birds. So the answer is A.

Someone suggested that everything to be sent to the base on the moon must be sterelized so that no bacteria of any kind are present.Do you think this is a good idea
Answer:
Yes.
Explanation:
Yes, it is a good idea by sterilizing everything because this sterilization process kills bacteria or other harmful microbes on the items and no chance of bacterial infection occurs in the base that is present on the moon. This sterilization process is very important in order to make the health of the crew members and scientists that lives in the base on the moon. If the bacteria or other harmful microbes enters in the base so its maintained environment will triggers its growth and infections in the humans so it is a good idea.
