Using the ultrasonication and agitation method of liposome preparation, what concentration of lipid is necessary to prepare liposomes with a diameter of 250 nm?.
The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
What are liposomes?Liposomes are vesicles which are made up of a lipid bilayer membrane.
Liposomes are important as delivery vehicles for substances such as drugs.
Ultrasonication is a method of liposomes preparation.
Solution of liposomes is dependent on the size.
The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.
Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

A heron, a large wading bird, is hunting in a pond that contains three types of prey: fish, frogs, and snakes. All three types of prey are abundant and provide the same amount of energy to the heron. The heron has the highest handling time capturing fish, an intermediate handling time capturing snakes, and the lowest handling time capturing frogs. What prey item would foraging theory predict that the heron should catch most frequently
The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.

Arrange the following events in the order in which they occurred.
Answer:
1→4→5→3→2
∙
Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.
∙
As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.
∙
The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.
∙
Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.
∙
Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.
∙
The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.
∙
Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.

In pea plants, tallness (t) is dominant to shortness (t). what are the predicted percentages of the genotypes of the offspring if a homozygous short plant is crossed with a heterozygous tall plant?
If a homozygous short plant (tt) is crossed with a heterozygous tall plant (Tt), the percentage of tall offsprings is 50% and the percentage of short offspring is 50%.
A heterozygous tall pea plant will have the genotype "Tt" and a homozygous short pea plant will have the genotype "tt" because homozygous means that both alleles are identical.Since 'T' is dominant over 't', any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is.The punett square of the following problem will have 2 squares with Tt genotype and 2 squares with tt genotype.Hence, the genotypic ratio of F1 generation will be
