ipn [44]

Answer:

The correct answer is -

1. hyaline cartilage

2.  fibrocartilage

3. hyaline cartilage

Explanation:

1. The hyaline cartilage covers the articular cartilage of the synovial joint that is translucent or clear as glass-like cartilage that has a firm consistency and a high amount of collagen.

2. A symphysis is an amphiarthrotic joint which is a fibrocartilagenous joint that joins with the adjacent bone. This is a very tough or strong tissue.

3. The growth plate of the long bone or epiphyseal plates are examples of synchondrosis,which is a hyaline cartilage composed tissue.

Why roots need to use different methods to absorb water and ions?
Reika [66]

Answer:

Root hair cells

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption

e. coli are grown on a medium containing lactose. once glucose is added to the medium, the bacteria stop fermenting lactose
djyliett [7]

The lac operon is an operon required for the transport and metabolism of lactose in E.coli. When lactose is introduced to the increased medium, the lac genes are expressed due to the fact allolactose binds to the Lac repressor protein and maintains it from binding to the lac operator. Allolactose is an isomer of lactose. Small quantities of allolactose are shaped when lactose enters into E. coli. allolactose binds to the repressor protein and reasons the conformational change. As a result of this, the repressor can no longer bind to the operator area and falls off. RNA polymerase can then bind to the promoter and transcribe the lac genes. After some time, when the level of lactose decreases as it is metabolized using enzymes, it causes the synthesis of the repressor from the regulator gene. This repressor binds to the operator gene and prevents RNA polymerase from transcribing the operon and the transcription is stopped. This type of law is acknowledged as negative regulation.

Allolactose is a disaccharide comparable to lactose. It consists of the monosaccharides D-galactose and D-glucose linked thru a β1-6 glycosidic linkage alternatively of the β1-4 linkage of lactose. It may additionally occur from the occasional transglycosylation of lactose through β-galactosidase.

There is nothing inherent in the nature of a large quadruped well-suited for long-distance running that requires us to call this
zzz [600]

Answer:

There is nothing inherent in the nature of a large quadruped well-suited for long-distance running that requires us to call this creature a "horse." This illustrates the linguistic design feature of <u>arbitrariness</u>

<h2>Explanation:</h2><h3>Arbitrariness : </h3>
  • No resemblance between the language signal and the thing that it represents. It means there is no connection or relationship between the linguistic forms and the meaning e.g when we pronounce the word house, it has nothing to do with the shape of the house.
  • In animal communication, there is often a strong recognizable link between the actual signal and the message an animal wishes to convey.
  • In human language, there is no link whatsoever between the signal and the message.
  • There is no intrinsic connection between, for example the word elephant and the animal it symbolizes.

Cross-cultural studies are important in studying behavioral biology because:
Firlakuza [10]
Cross cultural studies or which can be called ethology is important in studying behavioral biology because ethology is the scientific and objective study of an animal well particularly focuses on its behavioral under natural conditions  and viewing behavior as an evolutionary active trait. in some ways we can adopt the learning in this study to what we have.
