certain autoimmune diseases are associated with the presence of specific proteins on a person’s cells. these proteins are called ________ proteins.
Answers
Certain autoimmune diseases are associated with the presence of specific proteins on a person’s cells. these proteins are called HLA or MHC proteins.
An essential component of the immune system is the human leukocyte antigen (HLA) system, which is managed by genes on chromosome 6. It specifies cell surface molecules with the ability to deliver antigenic peptides to T cells' T-cell receptors (TCR). All nucleated cells have transmembrane glycoproteins that are Class I MHC molecules.
An alpha heavy chain is joined to a beta-2 microglobulin molecule to form intact class I molecules. Only professional antigen-presenting cells, the thymic epithelium, and activated T cells typically have class II MHC molecules; interferon (IFN)-gamma can stimulate the expression of class II MHC molecules in the majority of nucleated cells.

Conserving and Recycling Presentation
There are countless environmental, conservation, recycling, and energy resource organizations at city and state
levels (in addition to national and global organizations and agencies). In this assignment, you will research a city
or state organization in your hometown or state. For example, if you live in Colorado, you might research the
Colorado Association for Recycling
From your study of the organization, you will research and design methods for monitoring and minimizing human
impact on the environment. Your designs for monitoring and minimizing will come from the organization's purpose
or goals. For example, if the purpose of the organization is recycling, you could develop a method for how to
monitor the amount of recycled materials in the home and develop a method for minimizing the amount of
recyclables that end up in the trash at home.
You will create a presentation about the organization and your own design. You will describe what the
organization is about and how people can get involved. You will describe the design and details of your plans for
monitoring and minimizing human impact. Your presentation will be eight to ten slides in length and should
include the following information:

Which of the following is not a challenge to
the Maasai way of

A.
the declining lion population
B.
encroachment by farmers
C.
the loss of land to national parks
D.
the elimination of the kraal system
Answers
Answer:
D. the elimination of the kraal system
Explanation:
The Maasai tribe of East Africa is an example of a traditional economy. The Maasai tribe typically found in Kenya and Tanzania use livestock such as goats, sheep and cattle as social utility, it serves as the primary source of income.
Some of the events that posed a challenge to the Maasai way of life includes the following;
I. A decline in the lion population because killing a lion symbolizes a rite of passage with respect to the bravery of a warrior.
II. Encroachment of their lands by farmers.
III. The loss of their lands to national parks for recreational purposes.
However, the elimination of the kraal system is not a challenge to the Maasai way of life.
A kraal system was peculiar to the Zulus and it's usually an enclosure that surrounds a livestock. They're typically used as a place for performing sacrifices, act as a homestead for livestock, used as a defense against attack.
Answer:
D. the elimination of the kraal system
Explanation:
Unlike many other tribes in Kenya, the Maasai are semi-nomadic and pastoral: they live by herding cattle and goats. The Maasai have not fared well in modern Africa. ... In contrast, the Maasai have persisted in their traditional ways, so as Kenya takes more land for growing tribes and agriculture, they suffer.

Calculate how much water is expelled from a shale layer 1 km thick and 10 • 10 km in area, as it is buried from 1 km to 3 km depth, assuming its compaction is in equilibrium. Assume now that this is a source rock with 600 ppm weight percent mature hydrocarbon, of which 15% get expulsed in primary migration. How much oil is generated? What is the average concentration of oil, in ppm, in the water that escapes from the shale?
Answers
During the burial process, the shale layer expels approximately 10 km³ of water, and the average concentration of oil in this water is estimated to be 9 ppm.
Expelling water from a shale layer buried from 1 km to 3 km depth involves calculating the volume of water expelled. Assuming compaction equilibrium, the amount of oil generated can be determined based on the shale's hydrocarbon content and the percentage of oil expelled in primary migration.
The average concentration of oil in the water can be derived by dividing the amount of oil generated by the volume of expelled water.To calculate the volume of water expelled from the shale layer, we multiply its thickness (1 km) by its area (10 • 10 km), resulting in 10 km³. Assuming compaction equilibrium, this volume remains constant during burial.Next, we calculate the amount of oil generated. Considering the shale's hydrocarbon content of 600 ppm (weight percent) and assuming that 15% of the mature hydrocarbons are expelled in primary migration, we multiply 600 ppm by 0.15 to obtain 90 ppm.To determine the average concentration of oil in the expelled water, we divide the amount of oil generated (90 ppm) by the volume of expelled water (10 km³).This gives us an average concentration of 9 ppm (parts per million) of oil in the water escaping from the shale layer.Therefore, during the burial process, the shale layer expels approximately 10 km³ of water, and the average concentration of oil in this water is estimated to be 9 ppm.

Ocean trenches: Group of answer choices Are caused by divergence at divergent boundaries. Are parallel continents and island arc volcanoes. Are created at transform boundaries during earthquakes. Are typically only ~10 meters deep.
Answers
Ocean trenches are formed by convergence at tectonic plate boundaries.
Ocean trenches are long and narrow trenches that form on the seafloor. They represent the deepest parts of the oceanic floor They may be found in all ocean basins, but the deepest ones form part of the Ring of Fire around the Pacific Ocean.
Ocean trenches are formed from the movement of tectonic plates. When two tectonic plates converge, the denser of the plates subducts under the other, creating a trench.
Alongside the trench, there is a small hill which marks the beginning point of the subducting area. Because oceanic crust is more dense than continental crust, oceanic crust always subducts when the two meet.

A star begins to form when a cloud of dust and gas collapses inward as a result of gravitational forces.
true or false
Answers
Answer:
true- As the cloud collapses, the gravitational force pulling the particles together becomes stronger than the forces holding them apart. This causes the cloud to collapse in on itself, which in turn causes the temperature and pressure in the center of the cloud to increase. These conditions are necessary for star formation.

Answers
The correct answer is A, The movement of heat by convection drives ocean currents.
The ocean is a vast body of saltwater covering around 71% of the Earth's surface. It plays a crucial role in sustaining life on our planet. Comprising five major basins—the Atlantic, Pacific, Indian, Southern, and Arctic—the ocean is home to an immense diversity of plant and animal species, supporting complex ecosystems.
The ocean serves multiple functions and has a profound impact on climate regulation. It absorbs and stores a significant amount of heat, helping to stabilize global temperatures. Additionally, it acts as a major carbon sink, absorbing large quantities of carbon dioxide from the atmosphere. The ocean also influences weather patterns, generating winds, currents, and precipitation.

Of the following, which one would most likely be triggered by an earthquake? A) solifluction B) rock avalanche C) slump D) soil creep
Answers
Answer:
"B) Rock avalanche."
Explanation:
Among the options provided, a rock avalanche is the most likely to be triggered by an earthquake. A rock avalanche refers to the rapid and catastrophic movement of large rock masses down a slope. It occurs when the stability of a steep rock face is compromised, often due to seismic activity or other triggers such as heavy rainfall.
During an earthquake, the ground shakes and experiences significant energy release, causing the rocks and geological formations to undergo stress and deformation. This can lead to the weakening of rock layers, fractures, and the dislodging of large rock masses. The intense shaking and ground movement associated with earthquakes can provide the necessary trigger for a rock avalanche to occur.
