Lisa [10]3 years ago
3 0

Answer:

<u>Functions of epithelial tissue:</u>

  • i. Epithelial tissue covers the body outside and lines the various cavities inside.
  • ii. Epithelial tissue lines the hollow organs, body cavities, blood vessels and ducts.
  • iii. Cells are rested on thin, doubled layered, non-cellular basement membrane.
  • iv. Epithelial tissue has nerve supply of its own.
  • v. Epithelial tissue is avascular (a = without, vascular = vessel), i.e. it lacks its own blood supply and hence, obtains nutrients which diffuse out of blood vessels.
  • vi. Epithelial tissue has the power of division and regeneration. The old injured dead cells are sloughed off regularly and are replaced by new ones.

What is the complimentary strand to AGG-CTA_AAC
Virty [35]

Answer: The complementary strand is TCC- GAT - TTG

Explanation: During DNA replication, each strand of the DNA serves as a template for the synthesis of a new strand, thereby producing two new DNA molecules, each with one new strand and one old strand. A template is a DNA strand that would allow nucleotide molecules to be lined up in a specific order and be joined to create another DNA with a unique sequence. This results in creation of a double stranded DNA in which each strand is complementary to the other. In nucleotide base pairing, Guanine pairs with Cytosine while Thymine pairs with Adenine.

G = C while T = A.

To measure the population density of monarch butterflies occupying a particular park, 100 butterflies are captured, marked with
Sav [38]

Answer:

Given merely 40 butterflies were marked, assumed that there were multiple captures of both marked and unmarked butterflies, that the butterflies caught in traps were on the loose to be caught again. There are two mathematical solutions for this, both yielding the same answer which is 100. 

• First, to each marked butterfly was taken twice (40 marked X2 = 80 captured) then of the unmarked butterflies the 120 captured must relate to 60 actual butterflies. In which 40 + 60 = 100. 

• Secondly, by means of ratios in which 80/200 = 40/X. In this case X also = 100 that will result to the estimated size of the population of wilson park is 100.
