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.

Electrons that provide the energy for the production of most of a cell's ATP are carried to the electron transport cham by molecules.
Answer:
The answer was not found :(
Explanation:
Merry Christmas and Happy Holidays!
Answer: The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP. The electron transport chain works as a proton pump: it pumps hydrogen ions (protons) through the membrane, and only allows them back through a protein (ATP synthase) which makes ATP.

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.

walls of an organism with chloroplasts and tissues?
A. peptidoglycan
C. hyphae
B. chitin
D. cellulose
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.

HELP ASAP PLEASE!! DUE IN 10 MINUTES !!! based on these results which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells
A:the red blood cells will absorb water and increase in size
B:the red blood cells will lose water and decrease in size
C:red blood cells will of first absorb water than lose water and maintain their normal size
D:the red blood cells will first lose water then absorb water and finally double in size
Answer:
The correct answer is - option B. the red blood cells will lose water and decrease in size.
Explanation:
The movement of the water takes place always from the high concentration region of solute to the low concentration of solute through a semi-permeable membrane. In this case, the representation is showing that placing the cell inside a solution with low concentration solute than the cell makes the cell increase the size, and placing it in a solution high concentration of solute makes it decrease in size due to the transfer of water from more water to the low water area.
Now placing the RBC in a solution with more salt concentration than the cell makes the solution hypertonic which means the solution has more solute concentration and less water so the water move from cell to the solution and cell will shrink and decrease in size.

Which of the following choices represents the approximate percentage of geologic time that humans have existed on Earth since its origin?
less than 1%
1.8%
11.8%
more than 25%
Answer:
less than 1%
Explanation:
The approximate percentage of the geologic time that humans have existed on the Earth since its origin is less than 1%.
The earth is about 4.6 billion years and much of its history has been without the present of human activities.
Hominis were the first human to appear on the surface of the earth. This was in the Miocene epoch which was about 6 million years ago. Compared to the age of the earth, this time lapse is very small and not up to 1%. Life first appeared on earth about 3.5billion years. Since then evolution has taken its due course to give what we have today.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.

A researcher has used in vitro mutagenesis to mutate a cloned gene and then has reinserted the mutated gene into a cell. To have the mutated sequence disable the function of the gene, what must then occur
Answer:
recombination resulting in replacement of the wild type with the mutated gene
Explanation:
Recombination is a process of the formation of new alleles when the original ones are broken down into bits and then ‘recombined’.
When mutation of a cloned gene occurs and the mutated gene is reinserted into a cell, the mutated sequence gene function will have to be disabled which involves recombination resulting in replacement of the wild type with the mutated gene.
