Answer:
Once water is in the xylem, it travels upwards - against the force of gravity - towards the rest of the plant. Water is able to move against gravity due to two forces: tension and cohesion. Tension is a 'sucking force' which is created when water evaporates from leaves (transpiration), pulling more water into the leaf.
Explanation:
Movement of Water and Minerals in the Xylem. Most plants obtain the water and minerals they need through their roots. The path taken is: soil -> roots -> stems -> leaves. The minerals (e.g., K+, Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).
Answer:
mineral salts
Explanation:
b) Give an example of an animal with radial symmetry and an example of an animal with bilateral symmetry.
b. Are a prominent structure in prokaryotic cells.
c. Possess their own DNA.
d. Are sites of ATP production.
Answer:
Option (a), (c) and (d).
Explanation:
The prokaryotes lacks the nucleus and the membrane bound organelles. Eukaryotes have well defined nucleus and the endomembrane system is present in eukaryotes.
The main site of the oxidative phosphorylation is the mitochondria in case of eukaryotes. The mitochondria are known as semi autonomous organelle as it contains its genetic material. As the oxidative phosphorylation occurs in mitochondria, this is the main site of ATP production. The mitochondria is a membrane bound organelle and absent in case of prokaryotes.
Thus, the correct answer is option (a), (c) and (d).
Answer:
The correct answer are
a. Are the sites of oxidative phosphorylation.
c. Possess their own DNA and
d. Are sites of ATP production.
Explanation:
Mitochondria are double membranous structures that are found in eukaryotes. These are structure present in almost all the eukaryotes. The process of aerobic respiration takes place in mitochondria.
Mitochondria have their own DNA which is smaller than nuclear DNA and are circular in shape like bacterial DNA.It is called the powerhouse of the cell because ATP synthesis takes place in mitochondria which provide energy to the cell.
The ATP is produced through the process of oxidative phosphorylation which occurs in the matrix and mitochondrial membrane. In oxidative phosphorylation, ATP is produced by energy released from the oxidation of NADH and FADH₂ molecules.
Therefore the correct answer is a,c, and d.
B. They develop a blastula
C. They eat dead or living
organisms
D. They make their own food
Answer:
D
Explanation:
plants make their own food not animals, hope this helped :)
Answer:
For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

I copied and pasted from https://www.americangeosciences.org/education/k5geosource/activities/investigations/fossils/how-fossils-form ,it might help for your work.
Answer:
The correct answer would be skeleton
Explanation:
I had the same question
Answer:
A few ways could be
-toxic waste
-trash and plastic
-sewage
-indirect contamination
-bacteria and parasites
-mining
-burning fossil fuels
-direct marine dumping
-oil leak
-chemical pesticides
Explanation:
These are the 10 I found and came up with but there are many detrimental ways that we directly and indirectly effect the pollution of water.
