Answer:
Option C.
Ocean acidification is the main ecological problem due to mariculture.
Explanation:
- Mariculture also known as the aquaculture that stands for the fish farming occupation.
- The main ecological problem that mariclture addresses is the environmental degradation especially the water pollution.
- Many studies suggests that the tradition of mariculture has been increasing the acidificaton in ocean water that is directly affecting the marine organisms and plants.
- A build up of organic material beneath fish farms impacts the flora and fauna of an area.
- That makes drastic changes on sediment chemistry.
In an endothermic reaction, energy is absorbed which causes the object to heat up.
The endocrine system is a collection of glands that regulate your metabolism, growth, sleep, mood and other things around your body.
The mechanism is straightforward: in Metaphase one of Meiosis, chromosomes line up in two lines, with homologous across from each other, which allows them to interact by crossing over. In Metaphase of Mitosis, the chromosomes are all lined up single file, so the homologous chromosomes cannot interact.
Answer:
The dominant curled wing allele is also a recessive lethal.
Explanation:
If we look at the F2 ratio we see that :
curled wings: straight wings= 160:80
=2:1
Hence, if curled wings is considered to be a dominant trait then Curled wings * straight wings
Dd x dd
Punnet square will be as follows :
d d
D | Dd | Dd
d | Dd | dd
Hence in order to get F2
Dd x dd
Punnet square will be the same as above if the F1 cross is Dd* Dd
D d
D DD Dd
d Dd dd
if DD is lethal then the ratio is
Dd:dd=2:1
that is curled wings: straight wings=2:1
Hence, The dominant curled wing allele is also a recessive lethal.
