Answer:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Explanation:
1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.
Examples of Biotic factors include
A) grass, flowers, and sunlight

Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for the same phenomenon. B. Natural selection is an outdated theory to explain how evolution took place. C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce. D. Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.
Answer:
C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
Thus, the correct answer is option C.

Which of the following are parts of a bacterial cell?
Select all that apply.
mitochondria
flagella
cell wall
pili
Answer:
It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.
Explanation:
Flagella, cell wall, and pili are parts of a bacterial cell.
What is a bacterial cell?Microscopically small, single-celled creatures known as bacteria are found in millions in every habitat, both within and outside of other living things.
Some bacteria are hazardous, but most serve a helpful role. They are employed in industrial and medical procedures and sustain a wide variety of living forms, including both plant and animal life.
Around 4 billion years ago, bacteria are assumed to be the initial lifeforms to emerge on the planet. The earliest fossilized creatures are bacteria-like ones. Most biological and some materials can be used as food by bacteria, and certain strains can withstand harsh environments.
New insights into the functions of the gut microbiome are being provided by this expanding interest in how microorganisms affect human health. Bacteria are prokaryotes that do not contain any membrane-bound organelles.
Therefore, flagella, cell wall, and pili are parts of the bacterial cell.

ANNOTATE Write the inputs and outputs of cellular respiration on this diagram.
Answer:
Inputs---- glucose and oxygen.
Outputs----- ATP, carbondioxide and water.
Explanation:
The inputs of cellular respiration are the glucose and oxygen whereas the outputs of cellular respiration are energy in the form of ATP, carbondioxide gas and water. cellular respiration is a process in which glucose is broken down in the presence of oxygen gas for the production of energy in the form of ATP molecules. Carbondioxide gas and water which are the waste materials also produced in the end of cellular respiration process. Cellular respiration is the reverse of photosynthesis.
Three common methods employed in the cleanup of oil spills are aeration of water, skimmer boats, and genetically engineered bacteria aeration of water, skimmer boats, and genetically engineered bacteria A aeration of water, phytoremediation, and genetically engineered bacteria aeration of water, phytoremediation, and genetically engineered bacteria B skimmer boats, high temperature incineration, and phytoremediation skimmer boats, high temperature incineration, and phytoremediation C large floating booms, high temperature incineration, and phytoremediation large floating booms, high temperature incineration, and phytoremediation D large floating booms, skimmer boats, and genetically engineered bacteria
Answer:
large floating booms, skimmer boats, and genetically engineered bacteria
Explanation:
Skimmers are used in the clean up of oil spills it makes use of containment skims that act like a fence and the surface of water and prevent the oil spill from moving or spreading across the water surface. It contains the oil into a particular place. Floating booms helps in the sucking out of oil in the confined area, its act like a vacuum pump and suck out all the oil spills available in the areas confined by the skimmers.
Bioremediation involves the use of microorganisms to clean up spills this micro organism breaks down this petroleum product into harmless substance through their metabolic activities. Genetically modified Bacterial can be use for this purpose to help break down this hydrocarbons and make them less toxic.

Examples of how humans negatively affect local ecosystems are
A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads
B. Planting trees and other plants to attract native species
C. Creating laws to prohibit fishing from local streams
D. Removing non-native species from the environment.
Answer:
A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads.
Explanation:
Removing non-native species from the environment helps the native ants to thrive without having any changes in the ecosystem effect them (i.e. new invasive animal).
Creating laws to prohibit fishing from local streams helps keep the fish alive and allowing them to continue to use this stream.
Planting trees and other plants to attract native species helps secure and grow the ecosystem of that area.
This leaves A as the answer.

You cross nonpure tall plants (Tt) and produce 200
offspring. Which of the following statements about
the offspring is correct?
A. All of the offspring will definitely be tall.
B. 150 of the offspring will definitely be tall.
C. There is a 75% chance that each offspring
will be tall.
O D. There is a 25% chance that each offspring
will be tall.
Answer:
C is the best answer
Explanation:
the dominate trait is in 3 of the four boxes
There is a 75% chance that each offspring will be tall. Therefore option C is correct.
When you cross non-pure tall plants (Tt), you are dealing with a heterozygous genotype, meaning the plants have one dominant (T) and one recessive (t) allele for the height trait.
The dominant allele (T) is responsible for the tall phenotype, while the recessive allele (t) leads to short plants. In this case, 75% of the offspring will likely receive the dominant allele from at least one parent (Tt or TT) and therefore be tall.
The remaining 25% will inherit the recessive allele from both parents (tt) and be short. This is based on the principles of Mendelian genetics and the Punnett square.
Therefore option C There is a 75% chance that each offspring will be tall is correct.

B. High blood viscosity increases the resistance in the blood vessels and leads to faster blood flow.
C. Low blood pH decreases the rate of diffusion through the blood vessels and leads to slower blood flow.
D. The changing of the shape of red blood cells to a crescent shape decreases resistance and leads to faster blood flow.
Explain why this is the correct answer and why the other ones are wrong:
Answer:
B
viscosity of blood causes an increased resistance in the blood vessels and
leads to slow blood flow
Explanation:
Viscosity refers to the thickness of blood. This thickness is caused by the number of red
blood cells. Thick blood travels through blood vessels at a slower rate than thin blood
