The right answer is Cells shrivel as water moves out of them.
Water intoxication (hyperhydration) occurs when too much water consumption causes a decrease in the concentration of electrolytes in the blood, partly because the electrolytes are eliminated in excessive amounts, on the other hand by increasing blood volume without sufficient electrolytes. When the intercellular (extracellular) medium is too diluted relative to the intracellular medium, the osmotic pressure induced by this difference can cause the cells concerned to explode (the cell wall ruptures under pressure), in the first place the nerve cells, which causes disorders brain that can be severe or even fatal.
Answer:
a. All of the answers are correct.
Explanation:
During conjugation a bacteria transfers it's genetic material to another bacteria. The genetic material has genes in a particular order so we can easily know the order of the genes through experimentation. The transfer of genes occurs as per the time allowed. If two genes are nearby then they will be transferred one after the other.
For example in the given question, gene A was transferred to recipient bacteria in 26 minutes, gene M was transferred in 37 minutes while gene T was transferred in 45 minutes, it simply means that the order of genes is A M T. Gene M was transferred to another bacteria after A was transferred because time required to transfer it is 37 minutes which is less than time required to transfer A which is 26 minutes. Gene T took maximum time to get transferred so it will be last to be transferred.
After calculation, we can easily infer that the genetic distance between A and M is 11 minutes (37 minutes - 26 minutes = 11 minutes). Similarly we can get genetic distance between A and T as 19 minutes and between M and T as 8 minutes. So all the given options are correct.
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.
An organ is a collection of different tissues that carries out a particular function (e.g. liver). An organ system is a collection of organs that functions to carry out a specific task in the organism (e.g. digestive system). At each level of organization, the structure helps determine the function.
Many scientist believe the life started after a big bang
