The plasma membrane is a selectively permeable membrane surrounding all cells, which separates the cell from its environment. It contains proteins and lipids, which regulate the movement of materials into and out of the cell. The plasma membrane is composed of a phospholipid bilayer with proteins embedded throughout it that give it structural integrity and assist with membrane transport.

The hydrophobic tail region of phospholipids repels water, while the hydrophilic head region is attracted to water. Therefore, the phospholipid bilayer forms a barrier between the cell and its surrounding aqueous environment that keeps the cell from dissolving in water. The hydrophobic tails are directed inward toward the membrane's center, shielding them from water molecules.

As a result, the membrane's interior is hydrophobic, making it difficult for water-soluble molecules to pass through. The hydrophilic heads are exposed to the extracellular and intracellular fluids. This is the most important reason why human cells do not dissolve in water because of the plasma membrane's structure. The phospholipid bilayer membrane has a critical role in maintaining homeostasis within the cell by regulating its internal and external environments.

It allows some substances to pass through and not others, which is known as selective permeability. The lipid bilayer acts as a hydrophobic barrier that protects the cell from the surrounding water-based environment, preventing it from dissolving in water. Thus, human cells do not dissolve in water due to the plasma membrane's structure, which has hydrophobic and hydrophilic regions that act as a barrier between the cell and the surrounding aqueous environment.

The hunter will hit the monkey regardless of whether the monkey was light or heavy.

The outcome of the hunter hitting the monkey does not depend on the weight of the monkey. The key factor in this scenario is the timing of the hunter's shot in relation to the monkey releasing its grip on the branch.

If the hunter accurately aimed and fired at the same instant as the monkey let go, the projectile from the blowgun has a high chance of hitting the monkey, irrespective of its weight. The weight of the monkey does not affect the trajectory or speed of the projectile once it is released from the blowgun.

The percentage of the progeny expected to have heart-shaped leaves and few spines (hl, ns) in a standard test cross between a hl ns / hl ns plant and a hl ns / hl ns plant is 8.7%.Explanation:A test cross is a cross between a homozygous recessive organism and a heterozygous organism that is unknown for the trait being examined.

Therefore, the F1 gametes are hl ns, so we can set up a Punnett square:|    |hl ns|hl ns||hl|hl ns|hl ns||ns|hl ns|ns ns|The Punnett square shows the possible offspring that can be produced. From the table above, the expected ratio of the genotype is 1:2:1, which means 25% of the expected offspring are hl ns / hl ns, 50% are hl ns / hl ns, and the remaining 25% are hl ns / hl ns.

Therefore, 25% of the offspring will have heart-shaped leaves and few spines (hl, ns).

The percentage can be calculated as:(25% / 100%) x (100%) = 25% or 0.25Alternatively.The percentage of the progeny expected to have heart-shaped leaves and few spines (hl, ns) is therefore:25% x 87.5% = 21.875% or 8.7% (rounded off to one decimal place).Therefore, the percentage of the progeny expected to have heart-shaped leaves and few spines (hl, ns) is 8.7%.

In the context of conservation biology, genetic diversity refers to the number and relative frequency of alleles in a population, species, or lineage. It is the variability in the genetic makeup of organisms in a particular population.

Genetic diversity is important in conservation biology as it affects the ability of species to adapt to changing environmental conditions and is thus essential for the long-term survival of a population or species. It is also important for maintaining the evolutionary potential of a species, as genetic diversity provides the raw material for natural selection to act upon.

In general, a higher level of genetic diversity within a population or species is considered to be desirable as it increases the likelihood of long-term survival in the face of environmental change or other threats. Thus, conservation biologists often focus on preserving genetic diversity as part of their efforts to protect endangered species and ecosystems.

a) Habital and Obligate Bipedalism are two different types of bipedalism which can be defined as:1. Habitual Bipedalism: It is a form of bipedalism that is not obligatory. Humans are an example of animals that practice habitual bipedalism.

This means that human beings are capable of walking upright or on two legs, but they also have the ability to walk on all four limbs.2. Obligate Bipedalism: It is the type of bipedalism that is mandatory. This is where the organism has to walk on two legs and cannot walk on all fours.

An example of an obligate biped is a bird.b) Here are three anatomical changes associated with obligate bipedalism:1. The Foramen Magnum Shift: The foramen magnum, which is the hole in the skull that the spinal cord passes through, moves to a more central position at the base of the skull, from a posterior location, so that the skull can balance on top of the spine while walking upright.
