What are three ways a plant's organ systems work together?
A The shoot system delivers food to the root system.
B. The root system delivers materials from the soil to the shoot
system
The ground tissue of the root system protects the vascular tissue
in roots
D. The ground tissue of the root system stores food for later use by
leaves
Answer: A, B, D
Explanation: credit to the comments on the other. I also did the test
The three ways through which a plant's organ systems work together are as follows:
The shoot system delivers food to the root system.The root system delivers materials from the soil to the shoot system. The ground tissue of the root system stores food for later use by leaves.Thus, the correct options are A, B, and D.
How do plants deliver water and nutrients to other parts?Plants deliver water and other nutrients to other parts with the help of vascular tissues like xylem and phloem.
Xylem transports water, nutrients, and other minerals from the soil to all parts.
Phloem mediates the migration of foods from the leaves to the rest of the plants.
The shoot system delivers food to the root system via the vascular tissue phloem. The root system delivers materials from the soil to the shoot system via the vascular tissue Xylem.
The ground tissue of the vascular plant is responsible for storing the carbohydrates constructed by the plants and utilized by the leaves when required.
Therefore, the correct options are A, B, and D.

Answer:
a. water
Explanation:
hello! all of the following are elements except a. water, because an element is a substance consisting of only one type of atom. water consists of two types of atoms: hydrogen and oxygen.
All of the following are elements except water which is a compound.
What is an element?An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all in solid state at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons which are present in the nucleus are the defining property of an element and are related to the atomic number.All atoms with same atomic number are atoms of same element.Different elements combine to form substances which are called as compounds.

Answer:
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve

A scientist is examining layers of the
earth and tracking information about
animal fossils found in each layer. For
many of the deeper layers there are
consistently large animal skulls but
there is a sudden shift in the skull size in
one layer and they are all much smaller
at that point for the remaining layers
until the earth's surface. What does this
suggest?
This suggests that sudden change that occur to the environment cause a different size animal to become the main species of that area.
Why the fossils of small skull organisms were found?This is because at that particular environment the small skull organisms can survive at that time as compared to big skull animals. The presence of a specific type of fossil in the soil layer shows that the fossil organism live at that time on this area due to the presence of good environmental conditions so we can conclude that environment was good for the small skull organisms at that time.
