For the answer to the question above, I think the answer is simply because <span>four legs characteristic is not special to mammals but the hair that is something more important and special characteristic of the mammals, that's why. I hope this helps

Hoochie [10]

The statement that is correct regarding the troposphere and the stratosphere is The ozone layer is in the stratosphere. The third one is true. The ozone layer acts as a protection layer that prevents UV light.

<h3>What are the layers of the atmosphere?</h3>

The atmosphere is divided into many layers, with the troposphere close to the earth and the thermosphere toward the sun, as shown in the diagram. in between two layers, such as the tropopause, which is present between the troposphere and the stratosphere. In the stratosphere, the ozone layer is present, which prevents the sun's UV rays from falling on the earth, and the troposphere is the region where the clouds are formed.

Hence, the correct answer is the third option, which is "The ozone layer is in the stratosphere."

Lelechka [254]

Answer:

EELG

(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein occurs in the Lumen of the Endopslamic Reticulum

(2) Synthesis of phosphatidylcholine occurs in the Endoplasmic Reticulum

(3) Degradation of misfolded ER protein ossurs in the Lysosome

(4) O-linked glycosylation occurs in the Golgiapparatus

Explanation:

1. The covalent attachment of a carbohydrate to a macromolecule such as proteins or lipids is known as glycosylation.

N-linked glycosylation is a very common form of glycosylation and it occurs in eukaryotes in the lumen of the endoplasmic reticulum.

The addition of the first GlcNAc oligosaccharides to the asparagine residue of a proteinmos an example of N-linked glycosylation.

2. Phosphatidylcholine is synthesized through the CDP-choline pathway which occurs at the cytoplasmic face of the endoplasmic reticulum. Choline entering the cell is immediately phosphorylated by choline kinase, converting choline to phosphocholine.

Phosphocholine is then converted to CDP-choline by the second enzyme in the pathway, CTP:phosphocholine cytidylyltransferase (CT).

The phosphocholine moiety is then added to diacylglycerol in a reaction catalyzed by CDP-choline:1,2-diacylgylcerol cholinephosphotransferase to complete the synthesis of phosphocholine.

3. Lysosomes are the cell organelles which are responsible for the breakdown of proteins as well as other components of the cell. Misfolded proteins are identified and transported to lysosomes through chaperone-mediated autophagy, macroautophagy and endocytosis, where they are then degraded.

4. O-linked glycosylation is a form of glycosylation that occurs in eukaryotes in the Golgi apparatus.

What is the study of fish known as in biology?​
klio [65]

Answer:

The study of fish is called Ichthyology.

Explanation:

Fish specimens are identified in the field by ichthyologists. Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution).

Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution). Large reference collections of preserved specimens are kept in museums as a permanent resource for present-day researchers as well as for future ones.

Debora [2.8K]

Answer:  pathogen–host coevolution

Explanation:

A major driver of evolution is Reciprocal coevolution between host and pathogen. Rather than pathogen, one-sided adaptation to a nonchanging host, high virulence specifically favoured during pathogen–host coevolution. In all of the independent replicate populations under coevolution, the pathogen ( B. thuringiensis ) genotype BT-679 with known nematocidal toxin genes of C. elegans and high virulence specifically swept to fixation but only some of them go under one-sided adaptation,

so relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance is due to the elevated copy numbers of the plasmid containing the nematocidal toxin genes .
