The  most  appropriate  lighting  for  a  reptile  enclosure  which  ensure  ultraviolet  -B  exposure.  Reptiles  depend  upon  skin  manufactured  vitamin D3 and  has  no capability to  use  the  vitamin  D3  which  is  available  in  the  food  they  eat.For  these  reason   reptile  must  bask  in   the  sun  or  the  UVB  emitting  bulb  which  help to  maintain  vitamin  D3.

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton
-BARSIC- [3]

Answer:

The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".

Explanation:

0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:

A: 3.21% (m/v) NaCl Solution  = crenation (higher than 0.9% (m/v) NaCl)

B: 1.65% (m/v) glucose Solution  = hemolysis (lower than 5.0% (m/v) glucose)

C: distilled H2O Solution  = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)

D: 6.97% (m/v) glucose Solution  = crenation (higher than 5.0% (m/v) glucose)

E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)

What is the green pigment found in the chloroplasts of both plants and algae?
Svetradugi [14.3K]


The correct answer is A - chlorophyll.

It is a green pigment found in the chloroplasts of green plants. Chloroplasts are mostly found in the leaves of green plants and also in some algae.

Plants use chlorophyll to trap light energy from the sun. Without the light energy, plants cannot be able to carry out the process of photosynthesis, which converts water and carbon dioxide  into starch that plants use for food. 

Photosynthesis also releases oxygen which is vital for animal life.

The anthropocentric viewpoint implies that: a. Engineers have an obligation to weigh the interests of animals as being more impo
bija089 [108]

Answer:

b. Engineers should consider how much pollution their devices create because of how human health is affected.

Explanation:

Anthropocentrism, is a worldview that argues that humans are more important and significant that any other entities or species in the world. This view point argues that humans possess greater intrinsic values compared to other species; this viewpoint sees humans as superiors while other entities are inferior to them and hence can be used by humans for their own benefit.

Therefore the anthropocentric viewpoint as it relates to environmental ethics implies that engineers should consider how much pollution their devices create because of how human health is affected.
