Answer:
mountainside: temperature extremes have more influencebeach: wind and waves have more influenceExplanation:
It depends on what you mean by "factors that control weathering" and where the beach and mountain are located.
If we assume that the rock on the mountain is at a place that has seasonal snow, and the beach is in a temperate climate, then we can make these observations.
The rock on the mountainside will be "weathered" by freezing and thawing, and by plant growth (roots). These will tend to enlarge any cracks in the rock, breaking it apart. While the mountainside may be windy, that wind may not carry particles that would tend to erode the rock surface.
__
The rock on a beach will be most affected by wave and water action, tending to smooth any exposed surface. Freezing and thawing action is less common, due to the moderating influence of the water on the local weather. In some cases, plant growth may also be a factor. Wind may pick up beach sand, further tending to smooth any exposed surfaces.

"Genes are regions of DNA that carry the code for making proteins."
Genes are regions of DNA on chromosomes that carry the code for making proteins, hence option D is correct.
What is DNA?One of the guiding concepts of molecular biology is the information transfer from DNA to RNA to proteins. It is so crucial that it is occasionally referred to as the "core dogma." Information from genes is utilized to generate proteins through the processes of transcription and translation.
The nucleotide sequences of DNA correspond to certain genes. These genes produce particular proteins with a role in phenotypic development. Proteins are the byproducts of genes, while DNA makes up genes. Between a gene and a phenotype, proteins act as an intermediate.
Your human anatomy is constructed and preserved by DNA. Genes are parts of your DNA that give you the physical traits that make you special.
Therefore, DNA on chromosomes that carry the code for making proteins, hence option D is correct.

What is the difference between innate and adaptive immunity
Answer:
One is inherited (innate) from parents and the other is acquired after birth (adaptive)
Explanation:
Immunity refers to the ability of an organism to withstand or defend itself against diseases and infections caused by foreign bodies e.g pathogenic microbes. There are two major types of immunity organisms employ viz: Innate immunity and Adaptive immunity.
Innate immunity, also called natural immunity is the type of immunity transferred from parents to their offsprings i.e. inherited. The innate immunity is the primary form of defense that works generally to prevent entry of these foreign bodies into the system. This immunity is not pathogen-specific. A good experience of innate immunity in almost all plants and animals is the skin.
Adaptive immunity, also called acquired immunity, is the type that is acquired by an organism after birth and triggered when the innate form of immunity fails. Adaptive immunity is pathogen-specific i.e. it is responsive to a particular foreign body. A good example are the B and T cells (lymphocytes).

What effects do keystone specie shave on an ecosystem?
A. They make prey species extinct
B. They reproduce biodiversity
C. They keep populations of species balanced
D. They cause primary disturbances.
Answer:c
Explanation:
Recent research has found that on one island of the Galapagos two finch species interbred. This interbreeding may have resulted in a hybrid species that ultimately led to the extinction of one of the species Darwin discovered. They call this speciation in reverse, or despeciation. Based on what you know about speciation, why are these terms appropriate?
Answer:
Speciation is the method by which unique species evolve from a common ancestor. In this case, two of these species that split from a common ancestor interbred and created a hybrid. This hybrid was apparently stronger and possibly better adapted to the environment, which led to extinction of a species formed by the initial speciation event.

Twenty-five people developed symptoms of nausea, vomiting, and diarrhea three to six hours after attending a church picnic where they ate a ham and green bean casserole with cream sauce. The most likely cause of this case of food intoxication is _________.
a. Cholera toxin.b. Erythrogenic toxin.c. Aflatoxin.d. Botulinum toxin.e. Staphylococcal enterotoxin.
Answer:
e. staphylococcal enterotoxin
Explanation:
Staphylococcal enterotoxin is a toxin that is produced by the bacteria Staphylococcus aureus. It is a toxin found inside the gastrointestinal tracts of the human body which is why it is called an enterotoxin and it results in food poisoning when consumed by humans.
Staphylococcal enterotoxin is proteinous in nature and it can be found on dairy products such as milk or cheeses that have been contaminated by Staphylococcus aureus.
After consumption of the contaminated milk or cheeses, the person begins to experience symptoms of nausea, diarrhea as well as vomiting.
Staphylococcal enterotoxin is a very heat stable toxin which means even though you heat up a food contaminated with this toxin, the bacteria may die by the toxins would still remain in the food.
The best way to avoid food poisoning by Staphylococcal enterotoxin is to avoid eating contaminated foods.
The likely cause of food intoxication with symptoms appearing within three to six hours after eating a ham and green bean casserole with cream sauce at a church picnic is Staphylococcal enterotoxin produced by Staphylococcus aureus.
Explanation:The most likely cause of the described case of food intoxication, where individuals developed symptoms such as nausea, vomiting, and diarrhea within three to six hours after eating at a church picnic, is Staphylococcal enterotoxin. This kind of food poisoning occurs when Staphylococcus aureus contaminates food and produces enterotoxins. These toxins can cause the mentioned symptoms quickly after ingestion and are commonly associated with improperly stored meat and dairy products or due to poor hygiene during food preparation.
Such incidents underline the importance of maintaining proper food safety measures like thorough handwashing, reheating cooked foods to the recommended temperature of at least 60 °C (140 °F), and ensuring raw meats are cooked adequately to prevent bacterial growth. Additionally, when faced with symptoms of gastrointestinal distress, oral rehydration therapy with electrolyte solutions is a key treatment modality, mainly to prevent dehydration and support recovery.
What is an accessory organ of digestion
Answer:
An organ that helps with digestion but is not part of the digestive tract. The accessory digestive organs are the tongue, salivary glands, pancreas, liver, and gallbladder.
Accessory organs of digestion, including the salivary glands, liver, pancreas, and gallbladder, provide critical enzymes and bile that aid in breaking down food into nutrients.
Explanation:An accessory organ of digestion is a vital component of the digestive system that assists in the breakdown of food. These organs are not part of the digestive tract itself through which food passes but contribute essential secretions that aid in digestion.
Accessory digestive organs include the salivary glands, which begin the chemical digestion in the mouth, and the gallbladder, liver, and pancreas, which release bile and enzymes into the small intestine. These secretions are critical for continuing the process of digestion, turning complex food substances into absorbable nutrients. The activity of these organs is regulated by hormones and their function is indispensable for a healthy digestion process.

Brine shrimp live in salt water, but the level of salt in the water where they reside can differ dramatically from day to day or longer time scales. In very high salt concentrations, a brine shrimp _____ salt across its gills and maintains an internal salt concentration that is _____ relative to the water where it lives. In lower salt concentrations, a brine shrimp _____ salt water across its gills and maintains an internal salt concentration that is _____ relative to the water where it lives.
Answer:
The correct answer is "excretes; hypotonic; absorbs, hypertonic".
Explanation:
Cell's homeostasis is only conserved in an isotonic solution, since cells that are in an hypertonic solution (high salt concentration) tend to loss water, and in hypotonic solution (low salt concentration) tend to absorb water. Brine shrimp lives in waters that are both, hypertonic and hypotonic and has adapted to overcome this issue by excreting and absorbing salt across its gills. In very high salt concentrations, a brine shrimp "excretes" salt across its gills and maintains an internal salt concentration that is "hypotonic" relative to the water where it lives. In lower salt concentrations, a brine shrimp "absorbs" salt water across its gills and maintains an internal salt concentration that is "hypertonic" relative to the water where it lives.
Final answer:
Brine shrimp secrete salt in high salt concentrations to maintain a lower internal salt level, and absorb salt water in low salt concentrations to maintain a higher internal salt level.
Explanation:
Brine shrimp live in environments where the salt concentration can vary significantly. They have adapted osmoregulatory mechanisms to maintain internal salt balance through their gills in response to the varying salinity of their surroundings.
In very high salt concentrations, a brine shrimp secretes salt across its gills and maintains an internal salt concentration that is lower relative to the water where it lives. Conversely, in lower salt concentrations, a brine shrimp absorbs salt water across its gills and maintains an internal salt concentration that is higher relative to the water where it lives. This regulation allows them to stay isotonic with their environment, thus surviving whether the water is hypotonic or hypertonic to their cells.
What would be the most obvious outcome of repeated cell cycles consisting of s phase and m phase only?
Answer:
The cells created would continuously shrink overtime, getting smaller and smaller
Explanation:
If repeated cell cycles consisting of the S phase and M phase only it would result in a smaller cell type.
What is the cell cycle?The cell cycle is the cyclic event in which, a cell divide into two cells, this process is necessary for the growth and reproduction of living organisms.
In the cell cycle, there are several, events that occur that begin with the growth of the cell and division, with replication of their DNA content and other organelles.
The phases of the cell cycle are G1, S, G2, M, and cytokinesis, if only the S phase and M phase, after every division cell gets shortened, because the actual growing phase G2 is escaped.
Therefore, smaller cell size is the outcome of repeated cell cycles consisting of the S phase and M phase only, which escape the G2 phase.
