Water is the most abundant molecule found in living organisms. Most mammals, in fact, are approximately 70% water by weight. Abo

ut two-thirds of this water is present inside cells. The other one-third is present outside cells (e.g., in blood plasma or other body fluids). Why is water so important to cells?

Answer:

Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn't move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling

Match the type of of evidence for evolution with the correct example. analogous structures vestigial structures homologous struc
gogolik [260]

• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.

Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.

• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.  

Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species.  Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.

• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.

The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.

• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.  

Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.

How are photosynthesis and cellular respiration different?
kari74 [83]

Answer:

The correct answer is B photosynthesis stores energy,while cellular respiration releases energy.

Explanation:

Photosynthesis is an anabolic process that utilizes the atmospheric CO2 along with water molecule as a electron donor to generate glucose sugar and oxygen gas.Photosynthesis helps to store the light energy in form of chemical energy in the bonds of glucose molecules produced during photosynthesis..

 on the other hand cellular respiration is a catabolic process that oxidizes glucose to generate energy in form of ATP along with CO2 and water as a byproduct.

Who would like to help me with this because I am homeschooled and I do not know 20 people to survey. I have maybe 3 people in my
larisa86 [58]
I would just survey whoever is in my house. And I will be honest I have no idea what the survey is about but obviously your school (k12 maybe?) would not expect you to go around the neighborhood asking random people where their knuckle hair is located. All I can say Is try your best. Hope this helped. XD
