One characteristic of domain archaea is their cell walls.
Answer:
B. Cellulose
Explanation:
Polysaccharide are substances that contains many units of monomers called MONOSACCHARIDE. They are carbohydrate molecules consisting of very long chains of monosaccharides like glucose, galactose etc.
An example of molecule that forms from strong chains of polysaccharides is CELLULOSE, which consists of long chains of glucose units linked together by B-1,4-glycosidic bonds. Cellulose is the most abundant polysaccharide on Earth found in plant cell walls.
When B cells encounter a pathogen, they <span>divide and produce large amounts of an antibody. The correct option among all the options that are given in the question is the second option or option "b". I hope that this is the answer you were looking for and it has actually come to your help.</span>
Answer:
Sea stars carry out life functions in diverse -and unique- ways (<em>read below</em>) and are able to respond to environmental changes through adaptations such as temperature regulation.
Explanation:
Sea stars are invertebrate organisms that belong to the Phylum Echinodermata and are adapted to life in the ocean. They carry out life functions in diverse kind of ways. Here are some examples:
- <u>Limb regeneration</u>: they are known for the impressive ability to regenerate their limbs, which they accomplish because almost all of their vital organs are located in the arms.
- <u>Feeding</u>: sea stars are generally carnivorous creatures. They use their suction-cupped feet to open clams, mussels, and oysters. On the other hand, there are some species that prefer to feed on detritus or organic matter.
- <u>Locomotion</u>: these organisms are able to move thanks to their water vascular system, as they do not possess a circulatory system. Water circulates throughout their body into their feet, allowing it to extend and move.
Response to environmental changes:
According to new research evidence, these marine creatures possess unique adaptations that are extremely helpful in regard to environmental changes. They are able to regulate their own temperature during changing tides. During high tides, sea stars absorb cold water that is later used when temperatures are too hot due to warm water and sunlight. This adaptation is crucial to respond to environmental changes such as climate change.
Adenosine TRI phosphate (ATP) while ADP is adenosine DI phosphate. ATP has a third phosphate group stuck on the end of the molecule. Phosphates are big, bulky moieties, and it is hard to add a third group onto an ADP molecule that already has two. Also, they have a strong net negative charge - so that makes it doubly hard to push negative charges together. So the bond between the third phosphate group and the rest of the ATP molecule is very high energy - it takes a lot of energy to form it. A
