How does air pressure (behave)?
Answer:
Pressure has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular to the surface. ... So the pressure would also push on the bottom of the box and on the sides.

describe why rocks found at the bottom of the river are smooth and flat.Please in your own words,My teacher would get mad
The rocks found at the bottom of a river smooth and flat because those are collides with each other.
Explanation:
At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.
This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.
Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.
What is Abrasion?Abrasion is the process of rubbing or scraping away a material, by rubbing against a rough surface or causing friction. This type of mechanical weathering can be brought about by a variety of things, including wind, water, snow, and human action. Rock, metal, plastic and wood are some of the materials that may be subject to abrasion.
This may result in material loss and modification of the appearance and texture of the surface. Natural features such as the smoothness of river boulders or the roundness of pebbles on a beach can also be the result of friction. Sandblasting, grinding and polishing are some examples of industrial abrasive applications.
Therefore, Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

Describe the rock layers shown in Diagram A and any forces acting on the rock.
The rock in diagram A has three horizons and no force acts on it.
What is a rock?A rock is a geological term that refers to solid materials, made up of crystals or grains of one or more minerals. Rock is the main material in the Earth's crust.
Four diagrams of the Earth's crust are shown in the image. All four have three horizons and different forces influence them except A. These forces are caused by the movements of the Earth's lithosphere and are represented by arrows in the direction of movement.
In the case of diagram A, having no arrow means that no force acts on it. Additionally, you can see the three horizons or layers that make up this sample of land.

What are the two theories that are combined in the synthetic theory of evolution?
The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
Synthetic theory of Evolution The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.

Which of the following statements regarding digestion and absorption of carbohydrates is TRUE? Lactose intolerance results from an insufficiency of the enzyme amylase. Digestible polysaccharides are broken down into the monosaccharides glucose, galactose, and fructose, which can be absorbed. Sucrose is the main form of carbohydrate that can be absorbed by active transport across the intestinal epithelium. Carbohydrate digestion begins in the stomach. Cellulose from plants is a polymer of glucose that can be easily digested and absorbed by the human GI tract.
Answer:
CARBOHYDRATE DIGESTION AND ABSORPTION
For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. In addition to starch, the other major dietary carbohydrates are the disaccharides lactose and sucrose, and the monosaccharide fructose. The monosaccharides produced by complete digestion of these dietary carbohydrates are glucose, galactose, and fructose.
The digestive process begins with salivary amylase, which randomly cleaves the α-1,4 linkages of starch. Although amylase digestion begins in the saliva, pancreatic α-amylase is more important to the complete digestion of starch (Fig. 19-1). Starch is degraded first to dextrins and then to a mixture of glucose, maltose, and isomaltose (containing the α-1,6 linkages that are not digested by amylase).
The major disaccharidases, located in the brush border of the intestinal lumen, are
•
Maltase—hydrolyzes maltose
•
Sucrase-isomaltase—hydrolyzes sucrose and isomaltose
•
Lactase—hydrolyzes lactose
Whenever lactose goes undigested, it is not absorbed and passes into the large intestine. Here lactose is acted on by the intestinal flora that ferment it, producing large quantities of CO2, hydrogen gas, methane, and organic acids; the last irritate the intestines, increasing intestinal motility. All these products have only one way out. Thus, the symptoms that characterize lactose intolerance are bloating and flatulence and, in extreme cases, a frothy diarrhea. Lactose intolerance is least common in Northern Europeans and their descendants and most common in descendants of Asian, African, and South American origin.
HISTOLOGY
Brush Border Dynamics
The unstirred brush border of the intestinal lumen consists of finger-like processes, known as microvilli, of the surface absorptive cells. Many enzymes associated with the process of digestion and absorption are located on the surface of these microvilli. This allows the products of digestion such as free fatty acids, amino acids, and monoglycerides to be absorbed by the cells rather than be swept into the lumen itself.

Which of the following is a correct association?
Answer:
The first one
Explanation:
because it has the most words on their.
The correct association is option a.The cell synthesises proteins and organelles in the G2 phase (also known as the "Gap 2 phase") of the cell cycle in order to prepare for cell division.
The cell enters the G2 phase following DNA replication, which takes place during the S phase. In order to manufacture the elements required for cell division, the cell continues to expand and goes through further protein synthesis during this phase. These proteins play a role in the development of the mitotic spindle, control of cell cycle checkpoints, and cytoskeleton organisation.
The cell also creates organelles like the mitochondria and endoplasmic reticulum to make sure there will be enough energy and cellular building blocks for the impending division in the phase.

If an invasive species emigrated from a continent to a small island near the continent, what would most likely occur on the island
Answer:
Organisms on the island would migrate to a larger island.
Invasive species can cause extinctions, reduce biodiversity, compete for resources, and modify environments.
What is an invasive species?An invasive species is a category of non-native species that has overtaken the habitat to which it was initially introduced.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Preventative measures are the most practical and secure method of managing invasive species. It is far more effective to deal with invasive species early on and quickly than to try and contain an extensive infestation. The invasive species may be the target of control and management measures if eradication is not achievable.

The diagram shows an ocean food web. Which organism is a primary consumer? krill elephant seal Killer whale Elephant seal O squid O penguin Penguin Leopard seal Squid Cod Krill Zooplankton Phytoplankton
Answer:
Krill
Explanation:
If you look at the diagram for this assignment, you can see the main organism that produces its own food is the phytoplankton. The animal that eats that organism is called a primary consumer. So, if you were to follow the arrow from the phytoplankton (or the producer), it would lead you to the zooplankton, krill, and cod. Since there are only one of these primary consumers as the choices, you would pick the only one available for the multiple choice, which would be krill :D
