I believe you're looking for "chemical digestion".
Chemical digestions is where food that we ate is digested into simpler and soluble molecules that can be absorbed by our body. Enzymes are used as a catalyst to speed up the reaction.
One example is the digestion of lipids. Enzyme named lipase is used to speed up the digestion of lipids into 3 fatty acid molecules and 1 glycerol. This way, our body can absorb these simple molecules, and use them in order to make our body function.
On the other hand, physical digestion does not include enzymes, such as chewing in our mouth, therefore, don't mix them up!
The answer is A) An inner skeleton made of bone or cartilage. Vertebrates have a column of bones that supports the body and protects the spinal cord, while invertebrates are animals that either have a soft body or a hard outer casing covering their body.
Answer:
The correct answer would be 187-188 genes.
The chromosome is defined as a thread-like structure formed by deoxyribonucleic acid (DNA ) and associated proteins.
It carries the genetic information an organism in the form of genes.
Genes refer to the coding sequence of the chromosome which specifically codes for the amino acid sequence of a protein.
The genome of the yeast consists of 32 chromosomes which have 6000 protein-coding genes.
As these chromosomes are equal in size that is, each contains the equal length of the DNA.
Thus, hypothetically we can say that each chromosome consists of 187-188 chromosomes (6000/32 = 187.5)
A. theory because it is an explanation that is supported by extensive observations, experimentation, and reasoning.
Explanation:
Evolution can best be described as a theory because it is an explanation that is widely supported by extensive observations, experimentation and reasoning.
Theories are formulated after careful observation into a particular phenomenon.
- Most theories provides a vivid explanation into an observed event or process.
- The theory of evolution is one of such theories that suggests that an organism changes in order to adapt to its environment.
- Some of the key figures who contributed to the study of evolution are J. B Lamarck, Charles Darwin, Williams Smith e.t.c
