5. On vacation at a lake, Saira's mom sees an interesting-looking rock formation. Saira just learned
about rocks in geology class and tells her mom that the formation is made of gneiss, a type of
metamorphic rock. How did this metamorphic rock form?
Answer:it was heated and under pressure
Explanation:
Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.
What is a metamorphic rock?Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.
In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering. Then erosion and transportation of these particles take place by the wind, water, or any biological agent.
The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

15. Explain how it would be possible to have a change in a single base of DNA, but have the protein NOT change and be functional.
Answer:
Nonsense mutation. A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.Sep 21, 2020

what are the parts of the digestive system and their functions?
Mouth - break down food mechanically and chemically
Salivary Glands - produce saliva that contains enzymes which chemically break down food
Esophagus - move food from mouth to stomach through a process called peristalsis
Stomach - chemically break down food with stomach acid, mechanically break down food with the contracting of stomach muscles
Liver - creates bile that helps with digestion, stores, distributes and breaks down nutrients
Gallbladder - temporarily stores bile and squeezes it into the small intestine to break down fat droplets
Pancreas - produces pancreatic juice that contains digestive enzymes and bicarbonate
Small Intestine - absorbs nutrients from chyme
Large Intestine - absorbs water and dries out food, turning it into waste
Rectum - stores waste before it leaves the body
Anus - an opening where waste exits the body
Diffusion in membrane cell
Answer:
when small molecules pass through the lipid bilayer of a cell membrane simple passive diffusion occurs
Explanation:
Diffusion is one form of passive transport that doesn't require the expenditure of cellular energy. A molecule can diffuse passively through the cell membrane if it's lipid-soluble, uncharged, and very small, or if a carrier molecule can assist it. ... The assisted process is known as facilitated diffusion.

Why postharvest physiology is important to maintain sustainable food supply on this planet. Please give named examples and discuss various biological factors associated with produce deterioration after harvest
Answer:
Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption
Explanation:
Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).

You now find new cells which contains 200 mM CaCl2 and 15 mM glucose. The cell membrane is permeable to Ca ions, impermeable to Cl- ions, impermeable to Na ions and impermeable to glucose. You transfer these cells into a solution which has 140 mM (NaCl) and 150 mM glucose. What happens to the cells after the solution and cell have come to equilibrium
Answer:
The correct answer would be - ions will move from solution 1 to solution 2 so the cell will shrink.
Explanation:
The concentration of CaCl2- = 200mM
CaCl2 dissociates in the three different ions in a solution and each has the same osmolarity
The concentration of glucose = 15 mM
So, the osmolarity of solution 1 would be:
3 × 200 + 15= 615 mM
Similarly, the osmolarity of the second solution would be
The concentration of NaCl = 140 mM
The concentration of glucose = 150 mM
NaCl dissociates in the two different ions in a solution and each has the same osmolarity
140×2+ 150= 430 mM
The solution has more concentration of ions than solution two so the movement of the calcium ion of the CaCl2- would be possible only and therefore, the cell in solution 1 will shrink.

A. Stem
B. Root system
C. Cell wall
D. Phloem
Answer: The stem, the stem keeps the plant stable. Much like our skeletal system.
The stem cells of the organ of a plant is most similar to a bone in animals. Hence option A is correct.
What is vertebrate?Vertebrate is defined as any terrestrial animal, which is the most prevalent subphylum of the phylum Chordata. Vertebrate animals are those that have a backbone. There are many vertebrates on the planet today, and they are divided into 7 classes according to their physiological and anatomical characteristics.
Stem cells are defined as unique human cells that can differentiate into a wide range of cell types, from brain cells to muscle cells. Stem cells can differentiate in the body into a wide range of various cell types. They act as the body's system for repairs. Adult stem cells and embryonic stem cells are the two primary categories of stem cells.
Thus, the stem cells of the organ of a plant is most similar to a bone in animals. Hence option A is correct.

What are 5 different types of heterotrophs, what do they eat, and give an example of an organism for each category.
Answer:
Five different types of heterotrophs are carnivores, herbivores, omnivores, scavengers, and detritivores.
Carnivores eat the meat of other animals. Example: Bear
Herbivores eat vegetation. Example: Deer
Omnivores eat a combination of both meat and vegetation. Example: Humans
Scavengers eat things left behind by carnivores and herbivores. Example: Raccoon
Detritivores eat small bits of organic matter, such as soil. Example: Worms
Edit: If you'd rather substitute one of those for a decomposer, Decomposers break down dead or decaying organisms. Example: Mushroom, or fungi.
