32. As gradient increases, what happens to the distance between isolines?

Biology
1 answer:
Annette [7]3 years ago
3 0

Answer: Because the interval between isolines is constant, their spacing gives an visual indication of the change that occurs over a given distance, called a gradient. Hope this helps :)

Answer:

B. Smaller fragments travel faster and farther than larger fragments.

Explanation: Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving. [2] Proteins are separated by charge in agarose because the pores of the gel are too large to sieve proteins.

Describe how the structures of proteins differ from the structures of carbohydrates
Masteriza [31]

Answer:

Both are considered macromolecules. I'll explain below

Explanation:

Proteins are like a huge Lego construction. Each individual piece gets pieced together to make a larger "thing" - Death Star, House, etc. Each individual piece is a monomer, and the larger construction is the polymer. The monomers are Amino Acids and they get pieced together to form the polymer that is called a protein. The linkage that they use is an amide bond, and in biology it is usually called a peptide bond.

Carbohydrates can be singular monomers or polymer units. They are made of completely different compounds - usually aldehydes or ketones. And they link together through different chemical linkages (acetal or ketal linkages for polymers,hemiacetal or hemiketal linkages for monomers).

Both can be large, 3D strucutres - proteins are only functional as a large, 3D structure, while carbohydrates can be singular.

Tear glands have vesicles that release their secretion by exocytosis. These are classified as ___________ glands. However, _____
Vilka [71]

Answer:

1. Merocrine

2. Holocrine

Explanation:

Merocrine glands are the exocrine glands that synthesize their secretions on ribosomes attached to rough ER. These secretions are packaged by the Golgi complex into the secretory vesicles and are released from the cell via exocytosis. Tear glands, salivary glands are some examples of merocrine glands.

The cells of holocrine glands do not have vesicles but accumulate a secretory product in their cytosol. The mature secretory cells rupture to release the secretory product. This results in the presence of large amounts of lipids from the plasma membrane and intracellular membranes in secretions of these glands. One example of a holocrine gland is an oil-producing gland of the skin.

Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
alisha [4.7K]

Answer:

Translocation

Explanation:

Translocation is a chromosomal defect in which part of a chromosome breaks off and reattaches backward on the same chromosome.

Translocation can happen due to many reasons like:

A) Some of the changes that arise around the time of conception  or production of sperm or egg.

B) The inheritance of altered chromosome from father or mother.

Translocations can be divided into two forms:

  • Reciprocal translocation
  • Robertsonian translocation.

In reciprocal translocations,  fragments of two chromosomes break off from two different places, break and swap each other's segments. While in  Robertsonian translocation one chromosome attached with other.

Hope it help!
