Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.

what is the next step in the scientific method, following forming a hypothesis?
A. Analyzing the data
B. stating the question
C. conducting an experiment
Hi there!
The answer to this question, I believe, would be C, conducting an experiment. When you make your hypothesis, you have already stated your question, analyzed the data, and formed a logical assumption that you need to prove is true. Your hypothesis is your logical assumption; therefore, you ought to experiment and see if your assumption - your hypothesis - is correct.

Explain the structure of the cerebrum:
Answer: The cerebrum, also known as the forebrain, is the largest part of the brain. It is derived embryologically from the telencephalon. The cerebrum consists of two cerebral hemispheres (right and left) separated by a deep longitudinal fissure which contains the corpus callosum. The cerebrum is the largest part of the brain. It consists of the cerebral cortex and other subcortical structures. It is composed of two cerebral hemispheres that are joined together by heavy, dense bands of fibre called the corpus callosum. The largest part of the brain. It is divided into two hemispheres, or halves, called the cerebral hemispheres. Areas within the cerebrum control muscle functions and also control speech, thought, emotions, reading, writing, and learning.
Explanation:
A major disturbance that the ecosystem was able to recover completely from.
Hello. Your question is incomplete. However, I managed to find a question exactly like yours on the internet and managed to realize that you forgot to say that your question asks you to give an example of the statement presented above.
Answer:
A major disturbance from which the ecosystem was able to recover completely was the disease that almost wiped out all of Ireland's potato in 1840.
Explanation:
You may have heard of the Irish Potato Famine, which was a time when the Irish population lived very difficult days, after an illness that almost decimated the country's potato plantations.
The potato was the main source of food for the Irish, but in 1840, a fungus called Phytophthora infestans, managed to infect almost all potato plantations in the country, preventing the potato from being harvested and could be consumed. This created major economic and social problems in Ireland, as people suffered from hunger, poverty and the diseases that arose, which caused many Irish people to immigrate to other countries, or to die.
The fungus plagued the ecosystem for years and only started to decrease in intensity in 1850, once the ecosystem started to recover. Currently, although the pest still exists, the Irish ecosystem is completely recovered and the pest is controlled and is unable to make such an impact.

How is the process of protein synthesis similar to the process of programming a computer? How is it different?
Answer:
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. ... Translation occurs at the ribosome, which consists of rRNA and proteins. In translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome.
Both the synthesis of proteins and computer programming entail a series of instructions that lead to a particular output. While programming a computer and making proteins have some parallels, they are essentially separate activities that take place in different domains and use different tools and procedures.
What are the similarities and differences between proteins and computer programming?Similarities between proteins and computer programming:
Protein synthesis and computer programming both involve a series of instructions that are carried out in a particular order to get the intended result.Both processes need input data to produce output, and both processes require input data.Both methods rely on a language or code that is used to specify the instructions.Differences between proteins and computer programming:
Protein synthesis is a biological process that takes place inside of cells, whereas computer programming is a human-made activity that takes place inside of a machine.DNA and RNA are used in protein synthesis, just as a programming language is used in computer programming.Ribosomes, tRNA, and amino acids are used in protein synthesis to create proteins, whereas compilers, interpreters, and machine code are used to create programme for computers.Therefore, both the synthesis of proteins and computer programming entail a series of instructions that lead to a particular output.

Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because:
A. Phosphorolysis reactions cleave bonds with phosphate instead of water.
B. Phosphorylase is a better enzyme than hexokinase
C. Phosphorylase produces a glucose phosphate without spending an ATP to do it
D. All of these
Answer:
A
Explanation:
The answer is a Because Phosphorolysis reactions cleave bonds with phosphate instead of water (: just trust me
Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because phosphorolysis reactions cleave bonds with phosphate instead of water. The correct option is A.
What is glycolysis?Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons.
The metabolic process that changes glucose into pyruvate is known as glycolysis.
The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.
In contrast to phosphorolysis reactions, which cleave bonds with phosphate rather than water, glycolysis can be thought of as having a larger energy yield because it begins with glycogen rather than glucose.
Not producing adenosine 5′-triphosphate is not the primary goal of glycolysis; rather, it is to produce pyruvate for the trichloroacetic acid (TCA) cycle.
By boosting the ratio of NADH to NAD+, the glycolytic synthesis of pyruvate lowers the cytosol.
Thus, the correct option is A.
