The cells that have the general role of interacting with target cells and then inducing changes in them are called T-cells.
What do you mean by Target cells?Target cells may be defined as a cell that is acted on selectively by a specific agent.
T-cells involve helper T cells (TH cells) and cytotoxic T cells (TC cells) which are represented by a cluster of differentiation CD4+ and CD8+ respectively.
Therefore, the cells that have the general role of interacting with target cells and then inducing changes in them are called T-cells.

What are some geological characteristics of glaciers in Glacier National Park?
Answer:
The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.

Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of knowns that were tested. Revise the experimental design by proposing ways to modify the experiment to increase your certainty in the identity of the unknowns
Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is : The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test color, malleability, melting points, and to test how shiny or dull it is. I would propose these to increase the certainty in the identity of the metals. Btw, please mark me brainliest.
Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".
The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.

In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark than cones.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is
needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a social consequence of not using the land
for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community
Preserving the ecosystem may upset residents in a community with a hospital shortage.
O If the wetland is protected, residents have fewer environmental concerns about the area.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.
The social consequence of not using the land is that it will protect the lives of species and prevents a reduction in carbon sequestering by the trees.
A social consequence refers to any unforeseen event which can be positive or negative, experienced by a society and has an effect on them.
A positive social consequence benefits a group of the socially connected group and can also stimulate future purpose.
A negative social consequence has its repercussions and can be attributed to negligence and bad factors.
Conservation of the ecosystem is paramount as well as the survival of the community.
A positive social consequence from the given information is that if the forested wetland is preserved to support a variety of species, It will protect the lives of the species and prevent a reduction in carbon sequestering by the trees.
The community could have emergency ambulances to cater for the movement of patients in case of emergency to the hospitals or educate them on how to take good care of their health and how to minimize hazards at home and offices.

after death, the cornea absorbs fluid and becomes opaque. in a living person, the cornea is translucent due to _______________.
Given what we know about human anatomy, we can confirm that the cornea of a live human is translucent due to the arrangement of its collagen fibers and the lack of vascularity.
One important factor in the translucent nature of the cornea and lens is its lack of vascularity. This area of the eye has few if any vascular components, which contributes to its lack of pigment.
However, the main component that contributes to the translucent nature of the human cornea is its very specific arrangement of collagen fibers.
The bundled nature of these fibers, together with the water content of the cornea, allow it to remain translucent.
