54. Amphibians are cold-blooded animals, meaning they do not have a constant body temperature but instead take on the temperature of their environment. They have moist, scaleless skin that absorbs water and oxygen, but that also makes them vulnerable to dehydration (loss of bodily fluids).
55. The first and foremost characteristic of the reptiles is that are cold blooded. They are able to regulate their inner body temperature to the temperature of the environment. They have scaly skins but absence of hair or fur. The scales of the reptiles develop as a surface cells filled with Keratin.
56. Characteristics of Birds. Birds are endothermic and, because they fly, they require large amounts of energy, necessitating a high metabolic rate. As with mammals, which are also endothermic, birds have an insulating covering that keeps heat in the body: feathers.
57. Mammary Glands.
Undercoat and Guard Hair.
Jaw and Ear Bones.
Four-Chambered Heart and Diaphragm.
Complex Brain Functions.
The first stage is TRANSCRIPTION, it is a process that takes place in the nucleus or in the cytosol, the DNA acts as a template to transcript it's information forming a new mARN molecule which contains the codons that codes an specific amino acid.
This mARN molecule will exit the nucleus and will be translated in the ribosomas that can be found in the cytosol or the Endoplasmic Reticulum. during TRANSLATION the mARN will be decoded to produce a polypeptide chain, this happens when the ribosome induces the binding of a tRNA anticodon sequences that are complementary to the mRNA codons, this will tell the ribosome which amino acid is needed to form the polypeptide chain.
It's important to clarify that in Prokaryotic cells, both of these stages take place in the cytosol since it doesn't have organelles binded by membrane unlike the Eukaryotic cells where the Transcription happens in the nucleus and the translation happens in the cytosol or endoplasmic reticulum
<span>The correct answer is D. Micromanipulation allows interaction with precision. This is done under a microscope. With micromanipulation, in-vitro fertilization has come true, and is helping thousands of parents to become parents.</span><span />
Answer:
five kingdoms
Explanation:
members of the domain eukaryotes have member-bound organelles including a nucleus containing genetic material and are represented by five kingdoms.
