Two common metamorphic rocks that typically lack foliation are ________ and ________.
Two common metamorphic rocks that typically lack foliation are Phyllite and schist.
What are metamorphic rocks?
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure of 100 megapascals or more, causing profound physical or chemical changes.
Moreover, metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
Hence, metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock.

Bacteria in the large intestine can produce folic acid.
Select one:
True
False
answer
TRUE!!!
Final answer:
Bacteria in the large intestine can indeed produce folic acid, as part of a complex ecosystem that contributes to various functions essential for health, such as vitamin synthesis, digestion, immunity, and preventing the growth of harmful bacteria.
Explanation:
It is True that bacteria in the large intestine can produce folic acid. The large intestine hosts a complex ecosystem called the gut microbiome, comprising trillions of bacteria. While many people are aware of their role in digestion and immunity, these bacteria also play an essential role in synthesizing certain vitamins. Specifically, gut bacteria are capable of producing various B vitamins, including folic acid (vitamin B9), as well as vitamin K.
These beneficial gut bacteria synthesize nutrients that the body cannot produce on its own, which are then absorbed through the large intestine into the bloodstream. This symbiotic relationship is crucial for maintaining good health. Dietary habits and certain medications can influence the composition of the microbiome and thereby affect the production of these vitamins. Hence, the role of intestinal bacteria extends beyond digestion to include a diverse array of functions that contribute to overall well-being.

Ammonia, which is a byproduct of protein metabolism, is converted to __________ primarily in the __________.
Final answer:
Ammonia, a byproduct of protein metabolism, is converted into urea in the liver to reduce toxicity and then excreted through urine primarily in the liver.
Explanation:
Ammonia, which is a byproduct of protein metabolism, is converted to urea primarily in the liver. During protein metabolism, amino acids are broken down and the amino group is removed in a process known as deamination. Ammonia (NH₃) is produced as a result. Because ammonia is toxic, the liver rapidly converts it into urea, which is a less toxic compound. The urea then travels to the kidneys, where it is excreted from the body through urine. Therefore, urea is the principal waste product in mammals, resulting from the nitrogen in amino acids.

Photosynthesis uses sunlight to convert water and carbon dioxide into what two things
Photosynthesis utilizes sunlight to convert water and carbon dioxide into food (glucose) and oxygen.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and most photosynthetic algae synthesize their own food with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_20[/tex] → [tex]C_6H_1_2O_6+ 6O_2+ 6H_2O[/tex].During the process, the inorganic carbon of carbon dioxide is converted into the organic carbon of carbohydrates.
The process of photosynthesis involves the following:
The absorption of light energy by the green pigment is known as chlorophyll.The conversion of captured light energy into chemical energy along with the splitting of water molecules into hydrogen and oxygen.The reduction of carbon dioxide into carbohydrates (glucose).Therefore, the process of photosynthesis utilizes sunlight to convert water and carbon dioxide into food (glucose) and oxygen.

d.all of the above?
Water is said to have a low vapor pressure. How does this property affect large bodies of liquid water on Earth? It prevents them from freezing. It prevents them from flowing underground. It prevents them from spreading onto land. It prevents them from drying out.
Answer: Option D
Explanation:
The water starts boiling at 100°C and at this stage all the water will be converted into vapor which is not possible as the temperature of water never reaches 100°C.
It has low vapor pressure and low volatility. Example: More petrol will be converted into vapor as compared to water at the same temperature.
hence, this property of water allows it to remain in liquid state and not being dried out during summers.

Thanks in advance
• Active transport and facilitated diffusion both involve cell membrane protein.
• Osmosis involves the movement of water toward the higher concentration
• Mitochondria inner membrane consist of many folds to increase the surface to allow more space for ATP synthesis.
• Prokaryotes do not contain a nucleus
• Semipermeable cell membranes are made of phospholipids that form a bilayer through this cell have greater level of structural support
• Pacific sea horse s body loses water to its environment through osmosis.
Further Explanation:
The cell membrane has an ability to control the flux of ions, amino acid, and gases, through a lipid bilayer.
The lipid bilayer is made up of phospholipids and these membranes have hydrophobic interior, a layer is selectively permeable and allow only small, non-polar molecule. large and polar molecule like glucose cant cross plasma membrane easily they require energy and carrier protein to transport.
Types of transport:
• Passive transport
• Active transport
In passive transport, movement of ions or small molecule according to their concentration gradient from higher concentration to lower concentration.
But large polar molecule or charged molecule example glucose,Na+ require carrier protein to transport charged molecule across the membrane, do not require ATP or energy to transport.
Osmosis is a process by which diffusion of water takes place through cell membrane. To maintain the structure and function of cell it is important to maintain equal concentration of solute across the cell membrane.
These are the type of solutions
• Isotonic solution:The solution in which the concentration of solute is equal to the concentration inside the cell
• Hypertonic soluuution: The solution in which the concentration of solute is higher than the concentration inside the cell
• Hypotonic solution: The solution in which the concentrationnn of solute is lower than the concentration inside the cell
In active transport, they require ATP as well as carrier protein to transport molecule across the plasma membrane, an example of active transport is a sodium-potassium pump.
Mitochondria is present mostly in eukaryotes and not present in single celled organelle like RBC which lack nucleus.
Function of mitochondria
• Power house of cell
• TCA cycle occur in this
• Regulates membrane potential
Mitochondria is made up of two membrane outer layer and inner layer, space between the two membranes called intermembrane space,space enclosed by inner membrane is called matrix, inner membrane consists many folds to expand the surface area for ATP synthesis.
