PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASEIn a fish, blood circulates through __________, whereas in a mammal, it circulates through __________.
Answer:
fish: blood flows unidirectionally from the two-chambered heart through the gills and then the rest of the body.
mammal: Blood is pumped from veins of the systemic circuit into the right atrium of the heart, then into the right ventricle. Blood then enters the pulmonary circuit, and is oxygenated by the lungs. From the pulmonary circuit, blood re-enters the heart through the left atrium.

What is the value of transitional epithelium in the urinary system?.
Answer:
Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine.

Yeast can perform both anaerobic and aerobic respiration. Does the experiment demonstrate this fact? Explain your reasoning.
Answer:
Yeast can carry out both anaerobic respiration (fermentation) and aerobic respiration.
Explanation:
Both produce carbon dioxide, fermentation produces a much lower amount of ATP. Fermentation produces ethanol.
Answer: Yes.
Explanation:
it do demonstrate the fact because it has 2 different ways of testing whether or not oxygen effects the production of foam in the glasses.

Which one below will end up being expressed in the protein?
a) Intron
b) Exon
c) Transcription factor
d) Terminator
e) Promoter
Exons are the DNA fragments that get to be transcripted and translated into proteins. Option b) Exons end up being expressed in the protein.
What are introns and exons?Even though more than 70% of the DNA is related to genes, just a part of the genes is translated to proteins. Most genes have DNA segments that are not transcripted or translated intercalated with segments that are translated.
Introns are non-encoding sequences that produce interruptions in a eukaryotic gene. Exons are the encoding sequences. Exons are the nucleotidic sequences that do codify proteins.Most of the eukaryotic, multicellular genes contain introns in their sequences, intercalated with exons.
Introns are transcripted to mRNA molecules and get excised before translation by a specific mechanism. This occurs before the mRNA leaves the nucleus. The introns are excised and the exons must splice to form a unique molecule. This process is known as splicing.
Exonic sequences are the fragments that are transcripted and translated into proteins.
The correct option is b). Exons end up being expressed in the protein

When a person becomes infected with the influenza virus, cell-mediated immunity is activated. Why would the influenza virus initiate cell-mediated immunity? Describe the process of cell-mediated immunity as it would attack the influenza virus.
Cell-mediated immunity involves the activation of different specialized cells present in the immune system.
What is cell-mediated immunity?Cell-mediated immunity is a type of adaptive immune response that involves the activation of different specialized cells present in the immune system.
These cells include, among others, phagocytes (macrophages), cytotoxic T-lymphocytes, etc.
Cell-mediated immunity also involves the release of chemical messengers such as cytokines that activate immune responses (e.g. inflammation).
These immune responses act in a concerted mode to recognize and attack antigens present in the flu virus.

Why is nuclear fusion currently not feasible as a source of electrical energy?
Answer:
Fusion is generally impossible because the strongly repellent electrostatic forces between the positively charged nuclei prevent them from colliding and fusing. One of the key reasons we haven't been able to realize the promise of fusion is because its energy requirements are outrageously large. High-energy neutrons are produced during fusion reactions, although they are not radioactive in and of themselves. They do, however, have such a strong influence on the reactor's walls.

What happens when two haploid gametes join to form a zygote?
the zygote becomes haploid
the zygote immediately becomes an embryo
the zygote immediately becomes a fetus
the zygote becomes diploid
Answer:
forms a diploid zygote.
Explanation:
Fertilization joins two haploid gametes into a diploid zygote, the first cell of a new organism. The zygote enters G1 of the first cell cycle, and the organism begins to grow and develop through mitosis and cell division.
