Despite their seemingly simple anatomy and radial symmetry Sea urchins and sea star are a type of deuterostome, closely related to the chordates.
What are the characteristics of deuterostome?
Animals classified as deuterostomes share a common embryonic development.
The first opening during development known as the blastopore changes to the anus in deuterostomes while the mouth changes in protostomes.
They have a coelom, which forms as a result of enterocele (coelom from the digestive tract).
These creatures include the following,
- Chordata,
- Echinodermata,
- Hemichordata.
Hence the correct answer is Deuterostome.

Answer: 5 percent.
Explanation:according to a recent census in the US, only five percent of elderly people (65 years plus) live in homes, nursing houses, retirement places ecetera. Which is a lot less than one would believe.
Answer:
The correct answer will be-
1. Weed- 40%
2. Fruit fly- 60 %
3. Mice- 97.5 %
4. Chimpanzee-98.5 %
Explanation:
Charles Darwin suggested that all organism on earth have descended from a common ancestor. The modern technology-enabled humans to sequence the genome of an organism and compared them with each other.
When the human genome was compared with the genome of other organism found the similar sequences in them like - Weed shared 40% of the genome with humans, fruit fly shared 60% genome, mice showed 97.5% genome similarity and chimpanzees showed 98.5 % with the human genome.
On the basis of this, the chimpanzee was found to be the closest species to humans
The right answer is d. sugar molecules move outside of the membrane.
The simple diffusion is the diffusion through the plasma membrane (in the direction of the strong concentrations towards the weak concentrations, until equilibrium concentrations on both sides of the membrane). In the case that we have, the most concentrated compartment in glucose (that is inside the cell) will let it escape and go to the extracellular compartments until reaching equal concentrations between the two compartments.
Answer:
The member of the Mytai Lisgrogeous population which is most evolutionarily fit is the one which has the successes rate at reproduction.
Evolutionary fitness has been defined by evolutionary biologists as the ability to successfully adapt and reproduce regardless of the environment.
Explanation:
In the case of the Mytai Lisgorgeous, which is a species of bird found in the Amazon Forest, the males come in two variants:
- those that are very bright and colorful with very long tails and
- those with stubby tails and are of a drab brown color
The argument/question is based on observable phenomena which reveal that, while on one hand, the more colourful ones are more prone to predation than the other group with less plumage, on the other, the birds will a drab colour are less successful at reproduction as the female species of the birds prefer the brightly hued males.
So the logic behind the definition of fitness here is this, it holds no biological value if the members of a species have evolved to the point where they are no longer prone to predation if they cannot reproduce.
Cheers!
