The answer is D. A turtle suns itself on a rock during a cool day
The answers are A, B, & C. Steroid hormones have a
longer half-life than peptide hormones because steroid hormones ride on carrier
proteins in the blood. In other words, they
are bound to protein carriers that transport molecules across the membrane. They can also be stored temporarily in the adipose
tissue. And also, steroid hormones are sent to the nucleus where it regulates transcription
while peptides don’t require this process. This is the reason why the effects of
steroid hormones are exerted more slowly than peptides.
The correct answer is: sea stars
All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).
In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.
Humans are also deuterostomes.
Which of the chemical where are the chemical
The correct answer is - temperate rainforests of the Olympic Peninsula.
The Pacific northwest tree octopus is a fictional animal, thus it does not exist in the present, nor there is any proof that such a creature existed in the past, though there's every chance that it can evolve in the future.
According to the description of this fictional octopus species, unlike the octopuses we know, it is actually amphibious. This basically means that this octopus is able to live in the water, but also be terrestrial. It has developed from the octopuses in the East Pacific, and it started mostly to live on land, or rather on trees. It has used its eight tentacles in order to be able to have a perfect tool and easy arboreal life, swinging from one branch to another, being able to cover longer distances very easily, and manage to hunt with relative ease.
