Describe some of the challenges paleontologists encounter when studying fossils, and how they are able to use new technologies for overcoming those challenges.
Answer:
Many fossil records are incomplete because some animals were soft bodied or soft tissue which decays quickly. Also, due to movement of tectonic plates, fossils are destroyed so there are many new fossilised organisms which are destroyed and we don't know about them

T / F Nitrogen is present in carbohydrates but not proteins.
Nitrogen is present in proteins. So, the given statement is False.
What are Biomolecules?A biomolecule is defined as a chemical compound found in living organisms that mainly includes chemicals composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. Biomolecules are the building blocks of life and perform important functions in living organisms.
Biomolecules are of four types which are as follows: Carbohydrates, proteins, Nucleic acids and Lipids. Carbohydrates contain only the elements carbon, hydrogen and oxygen while the building blocks of proteins, amino acids which contain at least carbon, hydrogen, oxygen and nitrogen.
Thus, nitrogen is not present in carbohydrates, but it is present in proteins, making the given statement false.

A blue whale swims in the ocean. Which of Earth spheres are represented in this scenario?
O hydrosphere and biosphere
O atmosphere and lithosphere
O lithosphere and hydrosphere
O atmosphere and biosphere
Answer:
I believe the correct option is ''O hydrosphere and biosphere''
Explanation:
''A blue whale swims in the ocean.''
breaking up the sentence, ''A blue whale''. That is apart of the Biosphere as it includes all living orginisms, including said blue whale.
''Swims In the Ocean'', the Ocean is made up of the earths water, which sudgests the Hyrosphere as it is all waters on the earth's surface.

ATP provides energy needed to carry out many cellular functions. Which of the following processes does NOT require ATP? A. active transport of a protein across a membrane B. making more ATP C. passive transport of oxygen across a cell membrane D. muscle contractions
ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.
What is cellular function?Cellular function is defined as protein synthesis, translocation of molecules across the cell membrane, and cell division to create new cells. They provide the body with structure, take in food's nutrients, convert them into energy, and carry out certain functions. Additionally, cells have the ability to replicate themselves and contain the body's genetic material.
In primary active transport, molecules are moved across a membrane against their gradient directly using a chemical energy source (such as ATP). Ion transport, muscular contraction, nerve impulse transmission, substrate phosphorylation, and chemical synthesis are just a few of the processes that use ATP as an energy source. By adding a phosphate group to another molecule, ATP can drive biological operations.
Thus, ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.

La Fase más larga del Ciclo Celular es_____________________ y en ella ocurre____________________________________________________ _______________________________________________________________________________________________________________________________
Answer:
La fase más larga del ciclo celular es la interfase y en ella ocurre una gran producción de proteínas.
Explanation:
La célula pasa el 90% del tiempo del ciclo celular en la interfase, lo que significa que esta es la fase más larga del ciclo celular.
La interfase ocurre entre dos divisiones celulares consecutivas y es el período en el que la célula no se divide, sino que se prepara para ello, produciendo tantas proteínas como sea posible, que serán utilizadas en la división. Esta fase es tan grande que se divide en tres etapas llamadas G1, S y G2.
