Answer:
I will give a hypothesis. Just like a tree, when you cut a tree by its trunk, you will the rings. The rings around it represents the tree's age. So when you cut rock, the pores in the rock determine whether it is an old rock or a fossil rock.
Explanation:
The reason is, if it is limestone and it is an old rock, the pores will be slightly big and if the limestone is a fossil rock, then the pores will be bigger due to leaching or denaturing of the minerals in the rock through the ages.
Answer:
Radioactive elements all have a specific half-life, which is the time it takes for half of the radioactive elements in the fossil to disappear. In absolute dating, numbers are given to the ages of different fossils and rocks. To give an exact number or age range to a fossil, scientists use radiometric dating. This is where the half-lives of radioactive isotopes within the fossil or in the rock surrounding it are analyzed. Radioactive isotopes decay at a steady rate. By measuring the ratio of the radioactive isotope to the stable isotope it decays into, the number of completed half-lives can be estimated. Since you know the rate of decay, you can estimate dates with this ratio.
Explanation:
This is the process used to help scientists establish how old rocks and fossils are

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.

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.

Membranous sacs containing substances that were produced in the cell, such as neurotransmitters or hormones, are called VESICLES.
Vesicles are membrane sacks that store different chemical messengers such as neurotransmitters and hormones.For example, neurotransmitter vesicles are specific synaptic vesicles that store neurotransmitters in order to release them at the synaptic cleft.The release of neurotransmitters or hormones by membrane vesicles leads to the activation of the target cell.In conclusion, membranous sacs containing substances that were produced in the cell, such as neurotransmitters or hormones, are called VESICLES.
