Membrane lipids in tissue samples obtained from different parts of a reindeer’s leg have different fatty acid compositions. Memb

rane lipids from tissue near the hooves contain a larger proportion of unsaturated fatty acids than those from tissue in the upper leg. What is the significance of this observation?

Answer:

At lower temperature, membranes maintain fluidity by having a higher percentage of unsaturated fatty acids.

Explanation:

The fluidity of the membranes is affected by temperature. At lower temperature conditions, tight packing of saturated fatty acids makes the membranes more rigid. Therefore, membranes incorporate a higher proportion of unsaturated fatty acids to maintain the required fluidity. This is why the membrane lipids from the tissue near the hooves have a higher proportion of unsaturated fatty acids as the temperature of the tissues of a reindeer near extremities is lower than that of the tissues from the upper leg.

The answer to the question is the Marine snow.
In the deep ocean, marine snow is a continuous shower of mostly detritus falling from the upper layers of the water column. It is a significant means of exporting energy from the light-rich photic zone to the aphotic zone below. Marine snow particles are found throughout the world's oceans in all parts of the water column.

The lower rocks in the Muav limestone are 505 million years old. The upper rocks in the Redwall limestone are 340 million years
Alex777 [14]

Unconformity

Explanation:

The gap between the lower and upper limestone layer can be explained by the occurrence of an unconformity.

An unconformity is a break in stratigraphic record usually marked a prolong period of non-deposition or erosion.

A major break of several millions of years is called a hiatus. A minor break is a diastem.

  • During a period of non-deposition, no materials are brought into the basin.
  • This can last for several years until deposition resumes again.
  • Such a prolonged period of non-deposition causes a break in stratigraphic record.
  • At other times, stratigraphic records can be lost to erosion.
  • Erosion entails the washing away of the earth.
  • This will ultimately cause the loss of records between two strata till deposition resumes.
  • In most strata, periods of non-deposition and erosion usually takes place hand in hand.

sammy [17]

Answer:

The correct answer is genes.

Explanation:

The genes are the fundamental units of inheritance. The genes are passed to the offspring from the parents and comprise the information required to specify traits. The genes are aligned one after another on the compositions known as chromosomes. A chromosome comprises a lengthened and single molecule of DNA, of which only a part equivalent to a single gene. In humans, there are about 20000 genes aligned on their chromosomes.
