Answer:
With regard to bone decalcification secondary to hypocalcemia, what an endocrinologist and an orthopedist have in common is that they both focus on calcium levels.
Explanation:
Endocrinology and traumatology are two different medical specialties, however they can together treat a person with a metabolic disorder affecting the bones.
In the case of a person with thyroid problems, where probably the parathyroid glands are affected, there are low levels of calcium in the blood —hypocalcemia— which affects the bones secondarily by decalcification, both the endocrinologist and the traumatologist will coincide in the treatment of the serum calcium levels:
Endocrinologist will treat the hormonal problem that produces low calcium in the blood. Orthopedist will indicate a calcium replacement treatment to improve the levels of the mineral in the blood, and restore the calcium lost by the bones.The joint treatment of both specialists can guarantee the recovery of a patient with problems in the metabolism of calcium.

Explanation:
Susan, a mother with Type B blood, has a child with Type B blood. She claims that Craig, who has
Type O blood, is the father. He claims that he cannot possibly be the father. The judge aced her
BIO30 class, so she rules that:
a: susan cant be the real mother of the child; there must be an error at the hospital
b: susan is right and craig must pay child support
c: all of the above
d: its’s impossible to reach a decision based on the limited data available
Answer:
A child with type B blood can have a mother with type B blood and a father with type O blood so the judge grants her request and decides due to Susan is right and Craig must pay child support (option b).
Explanation:
Susan is right in this case because her son with type B blood may have a mother with type B blood and a father with type O blood.
Blood types, according to the ABO system, depend on the existence of surface antigens A or B —Types A, B and AB— or their absence in the erythrocyte membrane.
In the inheritance of blood groups A and B are co-dominant, while the absence of antigens —type O— is a recessive trait.
Assuming that Susan has a genotype B/B and that Craig has a genotype O/O:
Alleles O O
B B/O B/O
B B/O B/O
So it is very likely that the child is Craig's son and Susan is right.

Answer:
temperature, weather, the stratosphere,decreases, increases
Explanation:
edge 2020
The layers of the atmosphere are characterized by changes in temperature
Temperature is a physical quantity that expresses hot and cold or a measure of the average kinetic energy of the atoms or molecules in the system
The troposphere experiences large changes in weather
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere
Airplanes fly best in the stratosphere
The stratosphere is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere
The temperature in the troposphere
The troposphere is the lowest layer of the atmosphere, ranging from the Earth's surface to an altitude of about 10–15 km, depending on latitude and time of year. From: Encyclopedia of Atmospheric Sciences (Second Edition), 2015.
as you go higher, and in the stratosphere, it decreases as you go higher
Above the troposphere and below the mesosphere, we have the stratosphere. “Strat” means layer. This layer of our atmosphere has its own set of layers. There are no storms or turbulence here to mix up the air, so cold, heavy air is at the bottom and warm, light air is at the top.Learn more about troposphere and stratosphere

Recognizing the influence of subjective personal experiences and beliefs is the foundation of the __________ that humanistic theorists use to explain personality. A. behavioral perspective B. person-centered approach C. self-perception theory D. phenomenological approach
Answer:
D
Explanation:
Recognizing the influence of subjective personal experiences and beliefs is the foundation of the phenomenological approach that humanistic theorists use to explain personality.
Recognizing the influence of subjective personal experiences and beliefs is the foundation of the phenomenological approach that humanistic theorists use to explain personality.
What is the phenomenological approach?The phenomenological approach is a type of qualitative inquiry that places an emphasis on the lived and experiential components of a given construct, or how the phenomenon is felt at the time it occurs as opposed to what is thought about it or the meaning that is later assigned to it.
Exploring the lived experiences of women undergoing breast biopsy or the lived experiences of family members waiting for a loved one to undergo major surgery are two examples of phenomenology research.
Therefore, the phenomenological method employed by humanistic theorists to describe personality is based on the recognition of the impact of arbitrary, subjective, personal experiences and beliefs.

What would you expect to happen if you moved a marble statue from a hot, wet climate to a cool ,dry climate?
The rate of mechanical weathering would speed up.
The rate of chemical weathering would slow down.
The rates of any type of weathering would be unaffected.
The rate of chemical weathering would speed up.
Answer:
The answer is B
Explanation:
Hot and wet climates can cause rapid weathering in things like statues but moving the marble statue to an area of less humidity and cooler temperatures would greatly decrease the rate at which the statue would weather away.
If a marble statue is moved from a hot, wet climate to a cool, dry climate, the rate of chemical weathering would slow down. Therefore, option (B) is correct.
What is chemical weathering?Chemical weathering is the process of breaking down rocks and minerals through chemical reactions. This type of weathering involves a variety of chemical processes that can alter the composition and properties of rocks and minerals, making them more susceptible to erosion and decay.
Common examples of chemical weathering include the oxidation of minerals, dissolution of limestone, and hydrolysis of silicates. Over time, chemical weathering can have a significant impact on the landscape, shaping it through the breakdown and transformation of rocks and minerals.

5.2x10^-23 grams Nitrogen to atoms
Answer:
2.23 atoms
Explanation:
In this question, we first need to change the mass of Nitrogen to moles by using the formula;
mole = mass ÷ molar mass
Molar mass of Nitrogen = 14g/mol
Mass = 5.2x10^-23 grams
mole = 5.2x10^-23 ÷ 14
mole = 0.371 × 10^-23
mole = 3.71 × 10^-24 mol
Number of atoms in Nitrogen atom = 3.71 × 10^-24 mol × 6.02 × 10^23 atoms (avagadro constant)
= 22.3342 × 10^(-24+23)
= 22.33 × 10-¹
= 2.233 × 10°
= 2.23 atoms
Compare and contrast the light reactions of photosynthesis with the Calvin cycle reactions
Answer:
Just as the name implies, light-dependent reactions require sunlight. ... Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
If this helped you, please mark my answer the brainliest, (by clicking the little crown on my answer), it really helps a lot ! (づ｡◕‿‿◕｡)づ
Light-dependent reactions of photosynthesis occur on the thylakoid membrane. In this type of reactions energy from the sun is absorbed by the pigment chlorophyll of the chloroplast.
The reactant is water, ADP and the product formed is oxygen, ATP and NADPH.This reaction occurs during the daytime.Major protein complexes located in the thylakoid layers are ATP synthase, cytochrome B6f complex, Photosystem I and II.Calvin cycle is a light-independent reaction that happens in the outer membrane of the thylakoid called the stroma.
In this process, plants utilize carbon dioxide from the atmosphere to convert them into food.Calvin cycle completes using four actions: carbon fixation, modification, carbohydrate production and regeneration state.The outputs from the light-dependent reaction act as the reactants in this cycle.The end result of the Calvin cycle is the molecule of PGAL.To learn more about light-dependent and independent reactions follow the given link:

12. Describe how the structure of a frog's tongue is adapted to its diet.
13. Label the structures depicted in the following diagrams using the terms provided.
Answer:
It has a sticky and long tongue.
Explanation:
The structure of a frog's tongue is adapted to its diet because the frog has a sticky and long tongue. This stickiness helps to hold its food tightly while the more length of the tongue helps to catch prey that is far from the frog. Tongue of the frog is attached to the front of the mouth as compared to the back of the mouth. The frog's tongue then snaps back after catching its prey and throws the food down its throat.
Frogs have sticky tongues and their tongues can grab hairy, sticky, and slippery surfaces with ease.
The tongue of frogs is connected at the front of the lower jaw. They're not connected at the back of their throats like most organisms.
It should be noted that the frog projects the tongue out of the mouth through the use of an inertial projection mechanism. In this case, the jaw rapidly opens, the tongue rotates and the inertia of the tissue then leads the tongue to project toward its prey.

Explanation:
The reason is because underneath where it says the "key" is, it says that if you see RR it would be red.
There is no RR in any of the 4 boxes. Which means it would be 0%.
Same for the white, there is no WW in any of the boxes. Therefore 0%.
For the pink, you have all of the 4 boxes filled with the letters RW. That means they would all be pink! 100% would be your answer.

Imagine you were going to build a “green” building. What features would it have? What would it look like? How would it harmonize with the environment around it? Describe your green building using language that appeals to the senses (sight, sound, taste, touch and smell).
Answer:
Green building is a modern concept in architecture by means of which it is aimed at construction developments that are not invasive with the environment, or that affect the ecosystem in which they are built as little as possible, with the aim of leaving future generations an intact environment worth living in.
Thus, for a construction to conform to this concept, it must follow the following parameters:
-The construction must adapt to the natural environment, and not this to the construction.
-It has to be resource-efficient. Furthermore, the materials used must not be exploited indiscriminately or causing damage to the environment.
-The external area of the building must respect the natural patterns of the area where it is built, favoring a harmonic view between the building and the surroundings.
-Use of clean and renewable energy to supply the building.
