Human chorionic gonadotropin (hCG) is secrete by the embryo early in pregnancy to keep the corpus luteum for dying. This positive feedback will maintain the corpus luteum, which secretes Progesterone and Estrogens throughout pregnancy, in order to keep the endometrium well to nourish the embryo/fetus.

Answer:
A grassland is a biome where dominant vegetation is grasses, a consumer of this biome can be a herbivore (e.g., a rabbit). Coral reefs are home to millions of species of marine animals.
Coral reefs, seaweed and forest biome
Coral reefs are fundamental for protecting wildlife in marine ecosystems.
Seaweed is a common plant in the Euphotic Zone (Sunlight Zone, also called Epipelagic Zone), along with algae and phytoplankton.
Temperate broadleaf forests are represented by areas with marked warm and cool seasons that show moderate annual average temperatures (3 °C to 25 °C).
Examples of producers in a temperate broadleaf forest may be Eucalyptus species, whereas consumers may include, for example, elk

Answer:
c
Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square = 
where O = observed frequency and E = expected frequency
Chamber O E Chi-square
A 18 10 
= 6.4
B 2 10 
= 6.4
<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8
<em>Degree of freedom</em> = 2 - 1 = 1
<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
<em>The correct option is </em><em>c</em><em>.</em>
