Which of the following does NOT
Kazeer [188]

Answer:

D. Lots of vegetation

Explanation:

Urban heat islands form when cities replace natural land cover with dense concentrations of heat-absorbing pavement, buildings, and other surfaces. This has the impact of raising energy prices (for example, air conditioning), air pollution levels, and heat-related sickness and mortality.

The highlighted structure separates the oocyte from the externally located ________. zona pellucida primary follicle corona radi
Naya [18.7K]

Answer:

Granulosa cells                          

Explanation:

Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).

The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:

  • Primordial follicle
  • Primary follicle
  • Secondary follicle and
  • De Graaf follicles (This is the one shown in the image)

Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of <u><em>granulous cells</em></u>. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.    

The oocyte at this point gets surrounded by <u>zona pellucida</u> and <u>corona radiata </u>.    

The follicular antro (The highlighted structure) separates the oocyte from the externally located <u>granulosa cells</u> or follicular cells.

Adenine in DNA is complementary to
vesna_86 [32]

Answer:

DNA is also called deoxyribonucleic acid which is made up of two chains which wind around each other to form a double helix model. The 2 DNA strands are also called polynucleotides and they are made up of monomeric units known as nucleotides. These nucleotides are made up of one of four nitrogen-containing nucleobases: cytosine, guanine, adenine and thymine, a phosphate group, and sugar known as deoxyribose.  

Nitrogen bases present on the two separate polynucleotides strands are bound together with the help of base pairing (such as adenine with Thymine) and with hydrogen bonds to form double-stranded DNA.

So, adenine in DNA is complementary to thymine.
