what does a target cell require to respond to an extracellular signal molecule?
Name a plant organ, identify the tissues that make up this organ.
Hello!!
What tissues make up a leaf?
Leaves include two different types of photosynthetic parenchyma cells (palisade and spongy). Like all plant organs, they also contain vascular tissue (not shown). Monocots tend to have parallel veins of vascular tissue in leaves, while dicots tend to have branched or net-like veins of vascular tissue in the leaves.

The enzyme found in stem cells and cancer cells that allows these cells to never enter replicative senescence is:
Answer:
Telomerase is found in high levels in germline cells (egg and sperm) and stem cells. In these cells telomere length is maintained after DNA replication and the cells do not show signs of ageing.
Lichens are not single organisms, but algae and fungi that function together. The algae use photosynthesis to make food for both organisms. The fungi produce digestive chemicals and absorb nutrients for both organisms.
How does the biological activity of lichens cause weathering in rocks?
Answer options with 4 options
A.
Lichens cause friction as they grow, which weathers the rocks.
B.
Lichens produce chemicals, which dissolve and weather the rocks.
C.
Lichens take in water, which freezes in cracks and weathers the rocks.
D.
Lichens absorb heat during photosynthesis, which weathers the rocks.
Answer:

In the diagram of the human digestive system, what organ is labelled 5?
Answer:
The large intestine
Explanation:
The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.
As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.
Hopefully that was helpful! :)

4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!
Answer:
The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.
For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.
Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.
Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.
However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.
