The falciform ligament separates the:_________.
wel

The falciform ligament separates the<u> a. right and left lobes of the liver.</u>

Explanation:

  • The falciform ligament is a ligament that attaches the liver to the front body wall, and separates the liver into the left medial lobe and left lateral lobe.
  • The falciform ligament is a broad and thin peritoneal ligament. It is sickle shaped and a remnant of the ventral mesentery of the fetus.
  • The falciform ligament droops down from the hilum of the liver.
  • It contains between its layers a small but variable amount of fat and its free edge contains the obliterated umbilical vein  and if present, the falciform artery and paraumbilical veins.
  • The falciform ligament divides the left and right subphrenic compartments but may still allow passage of fluid from one to the other.
  • The falciform ligament stretches obliquely from the front to the back of the abdomen, with one surface in contact with the peritoneum behind the right rectus abdominis muscle and the diaphragm, and the other in contact with the left lobe of the liver.

In guinea pigs, smooth coat (S) is dominant over rough coat ( s ) and black coat (B) is dominant over white coat (b). In the cro
hoa [83]

Answer:

9 out of 16 offsprings

Explanation:

This question involves two genes in guinea pig; one coding for coat texture and the other for coat color. The alleles for smooth coat (S) and black coat (B) are dominant over rough coat (s) and white coat (b).

In this question, two heterozygous guinea pigs were crossed i.e. SsBb × SsBb. The gametes produced by each parent is as follows: SB, Sb, sB, sb. Using these gametes in a punnet square (see attached image), the proportion of offsprings will be:

Smooth black coat (S_B_) = 9

Smooth white coat (S_bb) = 3

Rough black coat (ssB_) = 3

Rough white coat (ssbb) = 1

Hence, according to this question, 9 out of 16 offsprings will have a smooth black coat on average.

The negative effects of tilling include _____. A increased soil erosion B reduced soil drainage C reduced need for energy input
Vikentia [17]

Answer:

A

Explanation:

Tilling agitates the topsoil and removes ‘unnecessary’ vegetation so the main crop can grow without competition. Tilling improves soil aeration and drainage for plants to grow well.  Nonetheless, it can lead to other consequences such as soil erosion because it loosens the soil and makes it easy to be carried away by wind and water.
