Shifting biomes could have consequences for the regions in which the shifts occur. Read the two cases below and decide which consequences would apply to one or both cases.Case 1: The biome of a small agricultural community in the western United States changes from grassland to desert. A species of migrating duck, which can carry bird flu, goes locally extinct.Case 2: The biome in northern Russia changes from tundra to taiga. Timber harvesting in the region becomes possible. Arctic foxes go locally extinct and are replaced by red foxes that commonly carry rabies.Sort each consequence based on whether it would apply to Case 1, Case 2, or botha. increased risk of wildfiresb. local economy suffersc. carbon storage decreasesd. agricultural production decreasese. carbon storage increasesf. disease vector range changesg. decreased water availabilityh. local economy thrivesi. species range changesCase 1Case 2Cases 1 and 2
Answers
Answer:
increased risk of wildfires- both
local economy suffers- Case 1
carbon storage decreases - Case 2
agricultural production decreases - Case 1
carbon storage increases - Case 1
disease vector range changes - Case 2
decreased water availability - Case 1
local economy thrives - Case 2
species range changes - Case 2
Explanation:
Fires are common to taiga biomes. Owing to the fact that the biome in case 1 changed from an agricultural community to a grassland and subsequently to a desert, agricultural productivity will decrease, the local economy will suffer, water availability is decreased and local economy suffers as a consequence of desertification.
On the other hand, in case 2, the diseases vector range as well as species range changes due to the change in the species of foxes from Artic foxes to red foxes that carry rabies. Carbon storage decreases as the taiga biome acts as a carbon sink. The local economy thrives due to timber production.
Lastly, species range changes both in case 1 and case 2 since there is a loss of species. Species range is the area where a particular species can be found during its lifetime. Certainly, the range of area where species are found changed in cases 1 and 2.
The consequences from the given cases are sorted as:
case 1: b. the local economy, c. carbon storage decreases, d. agricultural production decreases, f. disease vector range changes, i. species range changes, g. decreased water availability
Case 2: a. increased risk of wildfires, e. carbon storage increases, f. disease vector range changes, i. species range changes, h. the local economy thrives
Case 1 and 2 both: f. disease vector range changes, i. species range changes.
Consequences by shifting biomes?Case 1:
The shifting of biome from the agricultural community in the United States changes from grassland to desert result in consequences like decrease in the carbon storage and local economy suffers because of reduction in the agricultural production.
Also since the biome changes to the desert, it results in decreased water availability. Also since the biome changes, a species of migrating duck that carries flu goes locally extinct which implies that there will be a change in the range of species as well as the disease vector changes.
Case 2:
Since the biome in Russia changes from Tundra to Taiga now harvesting becomes possible and due to which carbon storage increases which in turn results in the flourishing of the local economy.
As an increase in the forests, there will be an increased risk of wildfires. Since the c foxes go locally extinct and are replaced by red foxes which carry rabies which implies that species range changes and the disease vector range changes.

Using the change in elevation from the rim to the river (2,085 m and 734 m, respectively, from the y-axis) and assuming that Hutton’s principle of uniformitarianism applies for erosion of the Grand Canyon, use an average downcutting erosion rate of 0.5 mm/yr to calculate a rough estimate for how long it might have taken to carve the Grand Canyon.
Answers
The time to carve the Grand Canyon based on the elevation will be 2702 years.
How to compute the value?From the information, it was stated that the principle of uniformitarianism applies erosion of the Grand Canyon and we are to use an average downcutting erosion rate of 0.5 mm/yr to calculate a rough estimate for how long it might have taken to carve the Grand Canyon.
This will be:
Change on elevation will simply be the difference between the change in the rim to the river.
= 2085 - 734
= 1351m
Therefore, the change in the elevation is 1351m..
Erosion rate = 0.5mm per year
The time to carve the Grand Canyon will be the change in the elevation divided by the number of years. This will be:
Change in elevation / Number of years
= 1351/0.5
= 2702years
Therefore, the time to carve the Grand Canyon based on the elevation will be 2702 years.

Which specialized cells help support the skeletal fibers in the cell?
Answers
Osteoblasts and osteocytes, specialized cells found in bone tissue, help support the skeletal fibers in the cell.
Osteoblasts and osteocytes are specialized cells that help support the skeletal fibers in the cell.
Osteoblasts: These cells are responsible for the formation of bone. They synthesize and secrete collagen and other proteins that make up the extracellular matrix of bone tissue. Osteoblasts also regulate the mineralization process by depositing calcium and other minerals onto the collagen matrix.Osteocytes: Once osteoblasts become surrounded by the bone matrix they have produced, they mature into osteocytes. Osteocytes are the most abundant cells in mature bone tissue. They are located in small spaces called lacunae and communicate with each other and with osteoblasts through tiny channels called canaliculi.Support for skeletal fibers: Osteoblasts and osteocytes play a crucial role in supporting the skeletal fibers in the cell. Osteoblasts actively produce and deposit the bone matrix, while osteocytes maintain and regulate the mineralization and remodeling of bone tissue. Together, these cells provide the structural support necessary for the integrity and strength of the skeletal fibers.In summary, osteoblasts and osteocytes are specialized cells that work together to support and maintain the skeletal fibers in the cell, contributing to the overall structure and function of the skeletal system.

What makes transmembrane proteins unique to non transmembrane proteins. i.e. what makes them become embedded in the er membrane while others don't?
Answers
Many transmembrane proteins feature as gateways to allow the transport of precise materials throughout the membrane. They frequently undergo large conformational adjustments to transport a substance thru the membrane. they may be commonly exceedingly hydrophobic and combine and precipitate in water.
Transmembrane and peripheral proteins are forms of membrane proteins present inside the cell membrane. Transmembrane proteins form channels and pores to move molecules across the membranes. in the meantime, the peripheral proteins on the extracellular surface are responsible for cellular-cell signaling and interactions.
Transmembrane proteins that amplify via the bilayer w/ part of their mass on either facet are amphipathic. -hydrophobic components (facet chains) interact with hydrophobic tails of lipids. -hydrophilic components are uncovered on both facets of the membrane.

Q: Explain Carbohydrate metabolism in fed state, importance and problems in human body. Support your answer by biochemical pathways.
Answers
Answer:
Explanation:
After having a carbohydrate rich meal concentration of some hormones, especially insulin change in your body. Insulin promotes the uptake of glucose by cells(particularly muscle cells, adipocytes, liver cells). It also increases the rate of glycolysis and glycogenesis and decreases the rate of gluconeogenesis and glycogenolysis.
These important metabolic pathways cause burning up glucose to make ATP that all cells in our body need and also storing it in the form of glycogen in the liver which is a very important food storage. Metabolism of carbohydrates also causes fat to be deposited in adipocytes which is basically why we have stuff like keto diets(no or very little carbohydrates and mainly fats consumed) for losing weight!

Part 1: David’s Case

period of time his behaviour changed markedly. He became very bad tempered and lashed out at family mem-

he got into an argument with her and beat her to death. The prosecution argued that he had lost his temper
and murdered her in a fit of rage. The jury believed the prosecution and he was sentenced to life in prison.
Discussion Questions:
• Based on your review of David’s case, what assumptions did you make about his behaviour?
• Do you think David was responsible for his crime?
• How significant is it that David was reported to be acting “out of character” in the days immediately prior to

Regarding David's responsibility for his crime, it is difficult to say. The prosecution argued that he had lost his temper and murdered the client in a fit of rage, but there may be other factors at play, such as mental illness or diminished capacity.
The fact that David was reported to be acting "out of character" in the days leading up to the murder is significant, as it suggests that there may be underlying issues that contributed to his behavior. However, it is important to note that this alone does not absolve him of responsibility for his actions.
In conclusion, David's case highlights the complex nature of criminal behavior and the many factors that can contribute to it. While it is important to hold individuals accountable for their actions, it is also important to consider the broader context in which those actions occurred.
if you examined a potato cell under a microscope how could you tell that it was a plant cell?
Answers
Answer:
When looking at a plant cell and an animal cell, you will notice one significant difference (though there are many more). A plant cell has one large central vacuole, whereas an animal cell has many.
Explanation:
Have a great day, and spread some positivity!
A plant cell can be identified by the presence of a cell wall, a large central vacuole, and chloroplasts.
The cell wall is a rigid structure that surrounds the cell membrane. It is made up of cellulose, a type of carbohydrate. The cell wall provides support and protection for the cell. Animal cells do not have a cell wall.
The central vacuole is a large space filled with water. It is located in the center of the cell. The central vacuole helps to maintain the cell's shape and turgor pressure. Animal cells do not have a central vacuole.
Chloroplasts are organelles that contain chlorophyll. Chlorophyll is the green pigment that allows plants to photosynthesize. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Animal cells do not have chloroplasts.
If you examined a potato cell under a microscope, you would be able to see these features. The cell wall would appear as a thin, clear layer around the cell. The central vacuole would appear as a large, empty space in the center of the cell. The chloroplasts would appear as green, oval-shaped organelles.

Steroidal hormones enter the cell directly and interact with DNA inside the nucleus. These hormones change gene expression, affecting the RNA that is produced and the proteins that are translated in a cell. Nonsteroid hormones do not enter the cell. Instead, they bind to specific receptors on the outside of the cell membrane. This triggers molecules called secondary messengers, such as cAMP, to begin their work of relaying information in the cell, where other chemicals, messengers, and proteins are involved to create a cellular response.
