1. An atom of which element has 37 protons, 48 neutrons and 1 valence electron? Answer:
Answer: Rubidium
Explanation:
The atom with 37 protons, 48 neutrons, and 1 valence electron is Rubidium (Rb).
Which element has 37 protons, 48 neutrons, and 1 valence electron?Rubidium (Rb) is the element that has 37 protons, 48 neutrons, and 1 valence electron. Protons and neutrons are located in the nucleus of an atom, while valence electrons are found in the outermost energy level or shell.
In the case of Rubidium, it has 37 protons which defines its atomic number and element identity. Also, it has 48 neutrons which contribute to its atomic mass. The valence electron of Rubidium is in the outermost energy level making it readily available for chemical reactions and interactions with other atoms.

5. Macromolecules which are both hydrophobic and hydrophilic and are a major
component of cell membranes are -
Answer:
All phospholipids have hydrophobic tails, consisting of the two hydrocarbon chains, and hydrophilic head groups, consisting of the phosphate group and its polar attachments. Consequently, phospholipids are amphipathic molecules, part water-soluble and part water-insoluble.
The appearance of free oxygen in the earths atmosphere led to the "great oxidation event" where did all of this oxygen come from
Answer:
So there's a simple explanation for the Great Oxidation Event. It was the cyanobacteria, pumping out unwanted oxygen, that transformed Earth's atmosphere. ... That means the cyanobacteria were busy pumping out oxygen for at least half a billion years before oxygen started appearing in the air.
Explanation:
explain whether the following statement is true or false: “All arteries carry blood with oxygen and all veins carry blood with carbon dioxide.”
Answer:
False
Explanation:
Important parts of circulatory system are heart, capillaries, veins, and arteries. The arteries are responsible for carrying red blood from heart and deliver oxygen to capillaries. Then capillaries deliver the waste carrying blood or deoxygenated blood to veins back to the heart.
But not all arteries carry blood with oxygen, the pulmonary arteries carry deoxygenated blood and not all veins carry blood with carbon dioxide, the pulmonary veins carry blood with oxygen.
Hence, the given statement is true.

and other hard tissues of dead animals, leaving stone in the shape of their skeleton.
Answer:
Permineralization.
Explanation:
Fossils is the marks or part of body left of the organisms when they were alive. It is remains of the organisms on the land. Scientists collect these fossils to study about the different creatures that were once present in the earth. The process of collecting and fossilization is called permineralization.

how dose light dependent reactions transform light energy into stored chemical energy
Answer:
The process of photosynthesis converts light energy to stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.
What number of cells is in metaphase
Answer:
1
Explanation:
The cell doesn't split until telophase, so there's still only one during metaphase. Chromosomes are still lining up during this phase.
The cell spends 90 percent of its time performing "everyday" functions, growing and preparing to divide during
Answer:
interphase
Explanation:
Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.
There are three phases in interphase G1, S and G2. During this phase cell undergoes several changes that include cell grows, DNA replicates and prepare itself for mitosis.
Hence, the answer is "interphase".
What is The major function of the cell membrane?

Give and example of functional differences between cells belonging to two different parts of the human body???
Answer:Cells of the digestive system are vastly different in structure and function from cells of the skeletal system. Cells of the body depend on each other to keep the body functioning as a unit.
Cells of the digestive system are different in nature and function from cells of the skeletal system. Cells are depend on each other to keep the body as a unit.
What is cell theory?Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Types of cell:
Prokaryotic Cell
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.
Eukaryotic cell
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organalle level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore, Cells of the digestive system are different in nature and function from cells of the skeletal system. Cells are depend on each other to keep the body as a unit.

Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis
Answer:
Explanation:
Photosynthesis is a light catalyzed chemical reaction that occurs in nature by all plants.
The process involves the reaction between carbon dioxide and water in the presence of sunlight.
This in turn produces glucose and oxygen gas.
The reaction expression is given as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
So, food is produced at the end of the reaction in form of glucose. In terms of energy, light energy is transformed into chemical energy stored in glucose.

Read the following excerpt about stem cells. Then use your knowledge about gene regulation to make a claim as to why stem cells function differently from differentiated cells.
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
Answer:
''Stem cells makes copies of itself whereas differentiated cells can't.''
Explanation:
stem cells function differently from differentiated cells because the stem cells divide and make copies of itself. It has the potential either to remain a stem cell or become another type of cell such as a muscle cell, a red blood cell, or a brain cell if the body needed while on the other hand, differentiated cells are specialized cells which performs specific functions and unable to divide.
Answer:
Stem cells are unspecialized cells that can make copies of themselves without limits when needed whereas differentiated cells can't, instead they become specialized as their body develops.
