Answer:
law of segregation
Explanation:
i just took the test on edg.
Answer: The correct answer is- This relationship is one of example of mutualism.
Mutualism can be described as a biological interaction between two species that live in close association with each other in a way that both the partners are benefited from each other. It is a type of symbiotic relationship.
Lichen shows mutualistic relationship between algae and fungus, where photosynthetic algae provides food source to the fungi and fungi in return provides protection to algae as well as provides nutrients from the surrounding.
Thus, it is an example of mutualism.
The last universal common ancestor (LUCA) is the most recent organism from which all organisms on Earth descended. While it is challenging to definitively determine the specific characteristics of LUCA, scientists have proposed certain properties that it likely possessed based on evolutionary and genetic evidence. Let's analyze each property mentioned in the question:
1. Simple cellular structure:
- LUCA is believed to have had a simple cellular structure. This means it likely had basic cellular components, such as a cell membrane, cytoplasm, and possibly some form of genetic material.
2. Anaerobic metabolism:
- LUCA is thought to have relied on anaerobic metabolism, which means it obtained energy from sources other than oxygen. This is because molecular oxygen was not abundant in the early Earth's atmosphere when LUCA is believed to have existed.
3. Prokaryotic cell type:
- It is widely accepted that LUCA was a prokaryote, meaning it had cells lacking a nucleus or other membrane-bound organelles. Prokaryotes are considered the most ancient type of cells on Earth.
4. Extremophile characteristics:
- While it is difficult to determine the specific environmental conditions in which LUCA lived, some scientists propose that it could have been an extremophile, capable of surviving in extreme environments like high temperatures, high salinity, or acidic conditions. However, this is still a topic of scientific debate and further research is needed.
5. Heterotrophic nutritional strategy:
- LUCA is believed to have been heterotrophic, meaning it obtained nutrients by consuming organic compounds produced by other organisms. This is in contrast to autotrophs, which can produce their own food through processes like photosynthesis.
In conclusion, based on current scientific understanding, LUCA is likely to have possessed the properties of a simple cellular structure, anaerobic metabolism, prokaryotic cell type, and a heterotrophic nutritional strategy. The presence of extremophile characteristics is still a subject of ongoing research and scientific investigation.
I hope this explanation clarifies the properties that LUCA is believed to have had. Let me know if you have any further questions.
The correct answer is 50.
Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.
Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
Answer: 50
Explanation:-
Proteins are polymers which are very critical for the normal functioning of the human body. They are essential for the structure, function, and regulation of the body’s tissues and organs.
Proteins are made up of number of smaller units called amino acids that are attached to one another by peptide bonds and thus form a long chain of polymer called as protein.
A protein at least 40 amino amino joined together by peptide bond is known as protein.
A) igneous
B) intrusive
C) sedimentary
D) metamorphic
C) sedimentary
Could I have brainliest?
your answer would be c) sedimentary rocks. they are broken bits of rock that sometimes hold organ bits, like seashells and fossils. hope this helped you!! have a great day!!
