<span>Reptiles and birds excrete waste as an insoluble white solid that is called uric acid. This means that these wastes are made of very little amount of water. This helps them to maintain internal homeostasis in hot climates since the presence of water allows them to cool easily.</span>
Repressor slows down transcription.
RNA Polymerase enzyme transcribes mRNA from DNA.
Explanation:
Promoters are the 100 to 900 bps long sequence of DNA, that helps in the initiation of transcription. The transcription gets slow down as repressor bind to the promoter region hampering the attachment of RNA Polymerase enzyme which is responsible for transcription.
The process of transcription is the conversion of DNA into mRNA as told in the central dogma of molecular biology. Enzyme responsible for transcription is RNA polymerase. It is the first phase of gene expression, where DNA strand is copied into mRNA called a primary transcript.
As means of locomotion, bacteria possess flagella.
Since UAG is a stop codon, it would introduce an early termination on the translation of the sequence.
Answer:
The digestive system excretes a solid waste, and the excretory system excretes liquid waste.
Explanation:
The digestive system is the system of the body that breaks down food substances to enhance so that they can absorb them. But it also excretes solid indigestible substances. For excreating, they use the defecation process.
Excretory system, on the other hand, is a system in the body that removes homeostatic wastes from the body by using a process which is called excretion. Excretory includes organs such as liver, sweat glands, lungs. Among this, the liver plays a critical role in the secretion of homeostatic wastes in the form of fluids.
The excretory system collects and then filters excess water which is present in the body and then excretes it as a liquid waste either from the liver, kidneys, or sweat glands on the skin through sweating.
