Explain how gravity causes rocks to fall off a cliff. ❤️
Answer:
Gravity has a strong pull and when rocks aren't in a good position/stable position they start to fall.
Gravitational Erosion
Explanation:
When chunks of stone fall from a mountainside to the ground below, it is because gravity pulled it down. When a glacier moves through a mountain range, slowly flattening or carving the earths surface in that area, it is because the pull of gravity forces the glacier downhill.

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.

what are the possible blood types of a child whose parents are both heterozygous for b blood type
Answer:
I believe the answer is:
If both are BB, the child will be BB. If one is BB and one is BO, the child has a 50% chance of being BB and 50% chance of being BO - both of which result in type B. However, if both parents are BO, there is a 25% chance of BB, a 50% chance of BO, and a 25% chance of OO (which results in type O).

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.

Radish color is controlled by a gene that exhibits incomplete dominance; purebred red radishes (RR) crossed with purebred white radishes (WW) make purple radishes (RW). What are the chances of producing purple offspring when you cross two purple parents?
Answer:
1/2
Explanation:
This question involves a single Gene coding for fruit color in radish plants. The gene exhibits incomplete dominance where the allele for red radish (R) and the allele for white radish (W) forms a hybrid with a purple radish (RW).
If a purebred red radish (RR) is crossed with purebred white radishes (WW), purple radishes (RW) will be formed. However, when the purple radishes are self-crossed i.e. RW × RW, the following gametes will be produced- R and W.
Using these gametes in a punnet square (see attached image), the following offsprings will be produced in the following proportions:
RR - red = 1/4
RW - purple = 2/4 or 1/2
WW - white = 1/4
Hence, the chances of producing purple offspring when you cross two purple parents is 1/2.
Energy can change in two different ways. It can undergo a transfer, or it can undergo a transformation. For each of these examples of how energy is changed, write the correct answer in the blank.
In photosynthesis, solar energy undergoes a _______ when it changes from light energy to chemical energy. When the sun warms Earth’s surface, thermal energy is ___________ to land and water.
Answer:
Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
Explanation:
The products that plants produce in photosynthesis are different from the products that animals and some bacteria produce in cellular respiration. The products of photosynthesis are
Answer: Carbohydrates in the form of glucose and oxygen as byproduct.
Explanation:
Photosynthesis is a process which occurs in green plants and in other autotrophs. In this process the autotrophs can prepare their own food by using reactants like water and carbon dioxide to produce glucose which is a carbohydrate which a major source of energy for plants and oxygen gas is released as a byproduct of this chemical reaction. On the contrary to this the cellular respiration can be defined as the process in which the biochemical oxidation of food occurs and energy is released in the form of ATP and carbon dioxide and water are produced.
Thus in photosynthesis the carbon dioxide and water are the reactants whereas in cellular respiration they are the products.
