Which of the following is a process that changes the composition of rocks and from one mineral to another?
Complete Question:
Which of the following is a process that changes the composition of rocks from one material to another?
Group of answer choices.
A. Erosion
B. Deposition
C. Physical weathering
D. Chemical weathering
Answer:
D. Chemical weathering
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering: it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering: it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
This ultimately implies that, chemical weathering refers to a process that changes the composition of rocks from one material to another. Some of the by products of chemical weathering are clay minerals, quartz, feldspar, muscovite, etc.

A student has a bag of Takis. They accidentally rip a hole in the bag and
the takis begin to fall onto the floor. As the takis fall they are losing
potential energy and gaining what type of energy?
Answer:
kinetic energy
Explanation:
Potential energy is the energy of an object while it is not moving, kinetic energy is an energy of an object while it is moving.
When an object is losing potential energy, it slowly starts moving.
when an object loses kinetic energy it slowly starts stopping.
So in a nutshell, the Takis are falling and losing their potential energy, while gaining kinetic energy.
Fully explain in your own words your thoughts on the following questions: Are mutations good or bad for a population?, IN YOUR OWN WORDS
Answer:
mutations can be either beneficial or harmful depending on the environment
Explanation:
Mutations can be defined as genetic changes in the nucleotide sequence of the genome of one organism. Mutations are usually neutral, but they can also be deleterious and/or beneficial depending on the environment. For example, recessive mutations that cause sickle-cell anemia, which is a recessive genetic disease that affects homo-zygous individuals, have shown to be advantageous for heterozygous individuals living in regions where malaria is endemic. Beneficial mutations can be selected by natural selection, thereby increasing their frequency in the population.

what is the main difference between the Eubacteria and Archaebacteria kingdoms and the Protista, Fungi, Plantae, and Animalia kingdoms?
Answer:
Organisms in the Eubacteria and Archaebacteria kingdoms are prokaryotic, where as all of the organisms in the other kingdoms are eukaryotic.
Explanation:
hope this helps <3
The prime difference between the Eubacteria and Archaebacteria kingdoms, and the Protista, Fungi, Plantae, and Animalia kingdoms is their cell wall.
Difference in the composition of cell wall in different kingdoms:A structural layer encircling some kinds of cells, that is, just external to the cell membrane is the cell wall. In all the kingdoms identified, the prime difference is seen in the composition of the cell walls present.
Following are the cell wall compositions of all the kingdoms:
In Eubacteria, cell wall is formed of peptidoglycan with muramic acid In Archaebacteria, cell wall is formed of proteins and polysaccharidesIn fungi, cell wall is formed of chitinIn Plantae, cell wall is formed of celluloseIn Animals, no cell wall is presentIn Protista, that is, the plant like protists, cell wall is formed of celluloseThus, the prime difference between all the kingdoms mentioned is the composition of the cell wall.

Which of the following is an element of custodial management?
Introducing new species into an ecosystem
Being able to control an animal’s environment
Using forest management principles in woodlands
Repairing any part of the environment destroyed by a natural disaster
Answer:
B. Being able to control an animal’s environment.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
Custodial management can be defined as a wildlife management technique that is typically focused on protecting or preventing any harm to the environment of living organisms such as plants and animals.
Basically, the main purpose of a custodial management is to minimize or mitigate any external influence on the living organisms and their natural habitat such as in wildlife. Thus, there are no interference by anyone on the animals in their natural habitats or wildlife.
Hence, an element of custodial management is being able to control an animal’s environment.

What's the similarities between phenotype and genotype? Pleaseeee help meee
Background: Phenotype is how a genetic trait physically looks, while genotype is the trait expressed as two letters.
Example:
-The genotype is BB
-The phenotype is brown hair
-The genotype is bb
-The phenotype is blond hair
-The genotype is Bb
-The phenotype is a mixed light brown hair
Therefore:
Both phenotype and genotype are expressions of genetic traits, but the phenotype is the letter form, and the genotype is the physical appearance/description.

if a red blood cell is placed in pure water what will happen?
Answer: it would swell up and Burst due to gaining osmosis.
Explanation:
Answer:
Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

in human beings urea is formed by.
Answer:
Urea is an organic nitrogen compound which is a waste product from the breakdown of proteins through nitrogen metabolism. It is excreted in dissolved form with the urine. It is used as a highly concentrated nitrogen fertilizer, and for making skin cosmetics.
Urea is found naturally in the urine of all mammals. When the body breaks down amino acids, its nitrogen is converted to the toxic substance ammonia, which in turn is converted to urea in the urea cycle. The amino acids are derived from degraded proteins.
Tissue with stellate cells whose function is communication
Answer:
Stellate cells are resident lipid-storing cells of the pancreas and liver that transdifferentiate to a myofibroblastic state in the context of tissue injury. Beyond having roles in tissue homeostasis, stellate cells are increasingly implicated in pathological fibrogenic and inflammatory programs that contribute to tissue fibrosis and that constitute a growth-permissive tumor microenvironment. Although the capacity of stellate cells for extracellular matrix production and remodeling has long been appreciated, recent research efforts have demonstrated diverse roles for stellate cells in regulation of epithelial cell fate, immune modulation, and tissue health. Our present understanding of stellate cell biology in health and disease is discussed here, as are emerging means to target these multifaceted cells for therapeutic benefit.
The stellate cells plays a crucial role in liver fibrosis.
Hepatic stellate cells is also known as perisinusoidal cells. The stellate cell is a type of cell that is involved in liver fibrosis, which is the formation of scar tissue in response to liver damage. These stellate cells promote the development of liver injury by secreting pro-inflammatory cytokines.
These cells have no function of communication. The stellate cell is also responsible for the secretion of collagen scar tissue, which results in cirrhosis in which the scar tissue takes the place of healthy tissue and the liver is damaged permanently. Stellate cells are responsible for healing of certain type of damages in the liver.

Complete table of digestive enzymes is:
Food type Enzyme acting on the food type Simpler substances produced
Protein Protease Amino acids
Carbohydrates Amylase Glucose
Fats Lipase Fatty acids and glycerol
Explanation:
Digestive enzymes are a group of substances whose function is to degrade food into simple compounds that can be easily absorbed by the body.
The main digestive enzymes are produced in the exocrine pancreas, corresponding to amylase, protease and lipase.
Amylase: is the enzyme responsible for breaking down carbohydrates into glucose, a simple molecule used as the body's main energy substrate. Proteases: act on food proteins to convert them into their monomers, amino acids. Lipases: are enzymes with an affinity for fats, degrading them by breaking their bonds to obtain fatty acids and glycerol.The simple molecules are easily absorbed at intestinal level, to be transported by the blood and distributed throughout the organism.
What happens when the monchondria stops working
Answer:
When monchondria stops you would be able to control your ATP.
Explanation:
Answer:
For our bodies the conversion from food energy to ATP happens in mitochondria. If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.
1) Which of the following activities would employ isometric contractions?
a) Flexing the elbow
b) Chewing food
c) Maintaining an upright posture
d) Running
e) Writing
Answer:
c. Maintaining an upright posture
Explanation:
"Isometric contraction" is all about increasing the tension in the muscles without shortening or lengthening the length of the muscles. There's also no movement.
Among the choices above, it is only "Maintaining an upright posture" that doesn't have movement; therefore, this employs the isometric contraction. This kind of contraction increases a person's strength. Another example of this contraction is holding a weight overhead.
Practice Problems. Kinetic and Potential Energy
1. Which has more kinetic energy a mosquito flying 20 miles per hour or a
biodist at that speed?
Why?
2. Which has more kinetic energy a mosquito flying 5 miles per hour or one flying
3. Thassing which of the following speed or mass - will increase kinetic energy
more? How do you know this?
3. Which has more gravitational potential energy: a cupcake on a bakery's top shelf
ora 9 inch cake next to it? Why?
5. Which has more gravitational potential energy the cupcake on the top shelf or
the cupcake on the middle shell Why?
6. What are some other kinds of potential energy other than gravitational potential
energy? Give 3 examples.
Answer: 1. Biodist(?) 2. If the one flying at 5mph is going faster(slower) than the other, it has more( less) KE 3. increasing speed increases KE more than increasing mass because KE = 0.5*m*v^2 second 3. Cake tin has greater mass and gravitational PE is proportional to mass. 5. The higher cupcake as greater gravitational PE because it is proportional to height. 6. Electrical, chemical and nuclear PE
Explanation:whatever a biodist is, it probably has greater mass than a mosquito so at the same velocity, has more KE
Unfortunately, “thassing” is unintelligible, but
KE = 0.5*m*v^2
Gravitational PE = m*g*h
