The development of the mouth and anus in the embryo helps establish animal body plans.
What influences an animal's body structure?The development of the mouth and anus in the embryo helps establish animal body designs. Protostomes are animals that grow their mouths first, whereas deuterostomes develop their anus first.A unique phenotypic characteristic that enables future radiation and the success of a taxonomic group is referred to as a "key innovation" in evolutionary biology. This term is also used to refer to an adaptive breakthrough or key adaption.The fundamental arrangement of the organs and bodily tissues is referred to as an animal body plan. Animal body plans often have two main elements in the animal kingdom: symmetry and the arrangement of tissues and bodily compartments.To learn more about Animal body plans refer to:

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.

*lf a strand has 35% adenine, what percent will be cytosine?
Answer:15% cytosine
Explanation:We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.
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.

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.
