Answer:
What is the function of adrenaline?
Adrenaline triggers the body's fight-or-flight response. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs. The body's ability to feel pain also decreases as a result of adrenaline, which is why you can continue running from or fighting danger even when injured. Adrenaline causes a noticeable increase in strength and performance, as well as heightened awareness, in stressful times. After the stress has subsided, adrenaline’s effect can last for up to an hour.
Explanation:
I think I helped
Answer:
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).
Fossil evidence cannot reveal which of the following important information about animals that have lived in the past? A. Size and weight. B. Diet and behavior. C. Exact year of death. D. Environment
Answer:
i would say B
Explanation:
Fossils can tell us about the size depending on how large the bones are. The year of death could possibly be determined by the way the bones look maybe, same with the environment, showing what type of animal; it could be a type of fish. But I believe there is no way fossils could show the diet and behavior of the animal.

give two functions of pericardium embrane
Understanding the Pericardium (Pericardial Sac) Your heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart
Answer:
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.

Why is a diet of only carbohydrates insufficient for long term survival?
Explanation:
While we can survive without sugar, it would be difficult to eliminate carbohydrates entirely from your diet. Carbohydrates are the body's main source of energy. In their absence, your body will use protein and fat for energy. It may also be hard to get enough fibre, which is important for long-term health
We can survive without sugar, but eliminating carbs is challenging. The body runs on carbohydrates. Protein and fat will fuel you without them. Fibre, essential for long-term health, may be hard to find.
Why is carbohydrate important?A diet heavy in carbs should make up a significant portion of a healthy person's daily intake of food. Carbohydrates are essential to life because they supply the body with glucose, which may then be transformed into the energy needed to carry out bodily functions and engage in physical activity.
Although it is possible to live without sugar, it would be challenging to completely cut carbohydrates out of one's diet. The primary source of fuel for the body is comprised of carbohydrates. In their absence, your body will resort to utilizing protein and fat as its primary sources of fuel. It may also be difficult to consume sufficient amounts of fiber, which is essential for maintaining good health over the long run.

How do humans study and measure caves at the Yucatan Peninsula?
Answer:
when i first read this i thought it said penis
Explanation:
GIVE ME ATTENTION
Answer:
They use different technological devices to measure caves at the Yucatan Peninsula.
Explanation:
Background Reading:
Human presence on the Yucatán Peninsula reaches back to the Late Pleistocene. Osteological evidence comes from submerged caves and sinkholes (cenotes) near Tulum in the Mexican state of Quintana Roo. Here we report on a new skeleton discovered by us in the Chan Hol underwater cave, dating to a minimum age of 9.9±0.1 ky BP based on 230Th/U-dating of flowstone overlying and encrusting human phalanges. This is the third Paleoindian human skeleton with mesocephalic cranial characteristics documented by us in the cave, of which a male individual named Chan Hol 2 described recently is one of the oldest human skeletons found on the American continent. The new discovery emphasizes the importance of the Chan Hol cave and other systems in the Tulum area for understanding the early peopling of the Americas. The new individual, here named Chan Hol 3, is a woman of about 30 years of age with three cranial traumas. There is also evidence for a possible trepanomal bacterial disease that caused severe alteration of the posterior parietal and occipital bones of the cranium. This is the first time that the presence of such disease is reported in a Paleoindian skeleton in the Americas. All ten early skeletons found so far in the submerged caves from the Yucatán Peninsula have mesocephalic cranial morphology, different to the dolicocephalic morphology for Paleoindians from Central Mexico with equivalent dates. This supports the presence of two morphologically different Paleoindian populations for Mexico, coexisting in different geographical areas during the Late Pleistocene-Early Holocene.

Which statement summarizes the law of segregation?
Gametes are passed in pairs, groups, or sets.
Traits that are dominant mask traits that are recessive.
Gametes carry one allele for each trait.
Traits are passed independently of one another.
Answer:
C) Gametes carry one allele for each trait.
Explanation:
The Law of segregation states that alleles separate during gamete formation, resulting in two gametes with a single allele each. The correct answer is C) Gametes carry one allele for each trait.
What states the segregation principle?The segregation principle states that there are alleles (dominant and recessive) coding for traits.
These alleles separate -segregate- during gamete formation, giving rise to two types of cells.
The segregation process is random, and each allele separates independently from the other alleles.
Each of the gametes carries only one allele coding for one trait.
The correct answer is C) Gametes carry one allele for each trait.

Complete the Punnett square below by showing the genetic makeup of the parent plats of the cross shown.Be sure to show both genes for each parent.
Answer:
The correct answer is -
Parent 1: RW, Parent 2: RR
Explanation:
In the given punnet square there are four offspring and it is a monohybrid cross between parent 1 and parent 2. The four offspring produced in this cross have RR, RR, RW, and RW alleles. By the genotype of the offsprings, it is clear that there are 50 percent pure or true-bred and 50 percent are heterozygous.
Each parent contribute two alleles and these alleles are independently assort in the zygote to form offspring so there must be R, R, R and W allele present in the parent
Parent 2 → R R
Parent 1 ↓ R RR RR (one allele (R) come from each parent in zygote)
W RW RW (one allele (R and W) come from each parent)

Answer:
The answer is "Abnormal Behavior"
Explanation:
Abnormal Behavior patterns are delegated "Mental Disorder" Mental messes include either enthusiastic pain (regularly melancholy or nervousness), fundamentally hindered working (trouble meeting duties at work, in the family, or then again in the public eye everywhere), or conduct that spots individuals in danger for individual affliction, torment, inability, or demise (e.g., self destruction endeavors, rehashed utilization of unsafe medications).

In the event that an individual's conduct remains fundamentally impeded throughout an all-inclusive time frame, nonetheless, a determination of a psychological issue might get proper.

Answer:
D. cellulose
Explanation:
:>
An organism having chloroplasts and tissues most likely has cellulose in its cell walls.
The correct answer is D
Simply put, what is cellulose?a complex carbohydrate that is the main component of plant cell walls and is typically obtained as a white stringy substance from plant matter (such as wood or cotton) that is used in the production of various products (such as rayon and paper). Another way to say this is that cellulose comes from plants.
Where does cellulose come from?A carbohydrate called cellulose is present in plant cell walls. A polysaccharide structure makes up the carbohydrate. Several sugar molecules are linked together chemically to form a lengthy chain known as a polysaccharide. Chitin, glycogen, cellulose, and starch are a few examples of polysaccharides.
