Student A described liquids.
professor190 [17]3 years ago
6 0

Answer: Option (A) is the correct answer.

Explanation:

In solids, particles are attracted towards each other by strong intermolecular forces and they do not have enough gap between them. Therefore, they are orderly arranged.

In liquids, though the particles are close and touch each other but there are gaps between their arrangement. Therefore, they are randomly arranged as the forces of attraction are not strong enough like in solids.

In gases, particles are weakly attracted towards each other and they constantly moves from one place to another.

In plasma, there are charged particles which have similar number of positively charged ions and negatively charged electrons.

Thus, we can conclude that out of the given options, student A described liquids.

b. false

Explanation:

Old world monkey and new world monkey do not have same dental formula . Dental formula is different for old world monkey as compare to new world monkey.

Old world monkey have 2.1.2.3 dental formula but on the other hand new world monkey have 2.1.3.3 dental formula .

Old world monkey have narrow nose but new world money have wide nose.Generally old world monkey are found in Asia and Africa that is why they called old world monkey.

Describe the structural or environmental change of your chosen macromolecule. Then predict the effect this change will have on t
Wewaii [24]

Answer:

Choosing protein as macromolecule.

Explanation:

The given environmental changes can lead to structural changes in protein as well:

pH - Several amino acids contain sidechains with practical gatherings that can promptly pick up or lose a proton. Changes in pH would prompt an adjustment in the charge of the amino acids, prompting charge-charge attraction or repilsion between non-interfacing amino parts.  

Temperature - High temperatures can prompt protein denaturation. Warmth can upset hydrogen bonding and hydrophobic interactions.  

Reduction or oxidation Environment - Some tertiary structure of protein folding is held by disulfide linkages. Reducing agent will lead to unfolding by introducing itself to break disulfide bonds.

Effect of these change: Sequence of amino acid and structure of protein molecule form determines function, any slight change to a protein's structure may result in the protein to become dysfunctional or produce different product.

Angiosperms, dicots

Explanation:

Angiosperms are highly differentiated vascular plants which can produce flowers and bear fruits with seeds in them. These flowering plants undergo reproduction and produces new plants. The reproductive parts like ovules and ovaries, stigma, stamen, pollen are all present in the flowers.

Angiosperms can either be a monocot or dicot. If they contain two embryonic leaves or cotyledons they are referred as dicots. Flowering angiosperms like geranium, magnolias are all dicots.

Geranium is a dicot angiosperms that produces small purple flowers.

Gymnosperms or bryophytes do not bear flowers or fruits. Monocots have only embryonic leaf.
