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.

Two different organisms were studied in a carrying capacity study. One was a paramecium population that grew in a flask in a lab
Gre4nikov [31]

Answer:

Paramecium- 0 days/ 50 paramecium

5 days/400 paramecium

10 days/ 900 paramecium

15 days/ 860 paramecium

Bear- 0 days/ 2 bears

20 years/ 26 bears

40 years/ 230 bears

60 years/ 250 bears

80 years/ 248 bears

100 years/ 252 bears

Explanation:

The population of the paramecium will keep on increasing until an equilibrium is reached. The resources will become limited and hence, the paramecium will start competition for the limited resources. As a result, the population of the paramecium will decline rapidly after equilibrium.

The growth rate of bear is very less as compared to that of paramecium growth rate. Along with the growth rate, there are other factors which will be responsible for its numbers such as resources, hunters etc. Also, it uses sexual method of reproduction hence the growth rate will not be like the paramecium growth rate.

The quintessential (most basic/ most important) moment of fertilization of the egg by the sperm cell occurs when
DedPeter [7]

The answer is pronuclei. A pronuclei is the state of the nucleus of either the sperm or the ovum after the sperm has entered the ovum but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane of the sperm pronuclei dissolves hence leaving no barrier for the two genetic materials to combine.

Explain how replacing asphalt with gravel or other permeable material can improve water quality.
Ira Lisetskai [31]
When coming to building something, some materials are more vulnerable to water and can wear away easier. Some can keep the water in, so depending on the material, the water quality can be better sustained.
