Explanation:

A dense concentration of plants exists, resulting in extremely high GPP and NPP. As a result, increased productivity increases biomass.

Tropical rainforests are densely packed with flora and other living species, yet the soil is depleted of nutrients due to the large amount of precipitation.

The majority of the carbon and vital nutrients in the rainforest are locked up in the living flora, dead timber, and decaying leaves. Because organic material decays so quickly, little nutrients reach the soil, leaving it nearly sterile.

Many tropical rainforest soils are extremely depleted and infertile. Millions of years of weathering have swept away the majority of the nutrients out of the soil.

The diaphragm, a dome-shaped sheet of muscle that separates the chest cavity from the abdomen, is the most important muscle used for inhalation.  

A deep breath, called diaphragmatic breathing, requires the diaphragm to contract. As the diaphragm relaxes, air passively leaves the lungs.

Crucial advantage of the daguerreotype method is that it resulted in sharper images than the competition.

Daguerreotypes was an early photographs method on a light-sensitive metal plate coated in crystals. A daguerreotype just needed just twenty minutes exposure. Daguerreotype, produced an opaque original positive that could be duplicated only by copying it with a camera.

There are advantages of the daguerreotype  they produce crystal clear images , It was the first commercially successful photography method in photography history . other disadvantage includes  it has a long exposure time, it is expensive, and the cameras are very large.

Directional selection is the type of selection that is shown in the graph.

Directional selection is a type of natural selection when a single phenotype is favored, resulting in a steady shift in allele frequency in one direction. Populations frequently go through directional selection, which chooses phenotypes at one extreme of the range of existing variation, when the environment changes.

The evolution of the peppered moth in eighteenth- and nineteenth-century England is a prime illustration of this kind of selection. Prior to the Industrial Revolution, the moths' mainly pale color allowed them to blend in with the lichens and light-colored trees in their environment. The trees darkened as soot poured from industries, making it simpler for raptors to identify the light-colored moths.

Disruptive selection (or diversifying selection) is a type of natural selection in which traits with extreme values are preferred over those with moderate values.

Stabilizing selection is a kind of natural selection where genetic diversity declines as the population stabilizes on a specific attribute value.

Explanation:

An inversion is a genetic phenomenon that occurs when a chromosome breaks into two genomic sites, thereby the resulting DNA fragment is reversed and subsequently inserted into the same chromosome location. A pericentric inversion occurs when the chromosome breaks are located on opposite arms or sides of the chromosomal centromere. Moreover, crossing over (or recombination) is the exchange of genetic material between non-sister chromatids during gamete production. An inversion carrier, as in this case the woman who is heterozygous for a pericentric inversion, can produce four types of gametes. If there is no crossing over, half the chromatids will produce normal gametes (without the recombination event) and half the chromatids will produce balanced gametes that will transmit the pericentric inverted chromosome. On the other hand, if there is crossing over, half the chromatids will have one duplication on the first chromosome arm together with a deletion on the second chromosome arm, and the remaining half of the chromatids will have an inverse arrangement.

Plants first go through photosynthesis, using sunlight and carbon dioxide. This creates glucose. It then releases oxygen into the atmosphere as a byproduct. To convert the glucose into usable energy, the plant goes through cellular respiration, which converts oxygen and glucose into ATP.

Bisphosphoglycerate (BPG) is a small molecule that binds to positively charged groups on the beta (b) subunits of hemoglobin. Hemoglobin is a protein found in red blood cells that transports oxygen from .

the lungs to the tissues and organs of the body. The binding of BPG to the b subunits of hemoglobin reduces its affinity for oxygen, which is important in facilitating the release of oxygen in the tissues. This allows for efficient oxygen delivery to the body's tissues, particularly during times of high metabolic demand such as exercise. Overall, BPG plays a critical role in regulating the oxygen-carrying capacity of hemoglobin.

Answer:

The frequency of the non-taster phenotype among people of European descent is 49% or 0.49

Explanation:

Let us assume that the allele for tasting PTC is T, while that for not tasting PTC is t.

According to the Hardy-Weinberg equation : p² + 2pq + q² = 1

Also p + q = 1

Where p² is the frequency of individuals with the TT genotype for tasting PTC,; wow is the frequency of individuals with the heterozygous allele for tasting PTC, while q² is the frequency of the individuals with tt genotype expressed as the non-taster phenotype since the allele for tasting is dominant over that of the non-taster.

From the information provided 51% of people of European descent are tasters. Also, tasting PTC is dominant over non-tasting. This implies that individuals with TT genotype and Tt genotype will be phenotypically expressed as tasters.

Therefore p² + 2pq = 51% or 0.51

q² = 1 - p² + 2pq

q² = 1 - 0.51

q² = 0.49 or 49%

The frequency of the non-taster phenotype among people of European descent is 49% or 0.49

Analyzing ecological footprints reveals that b current demand by industrialized countries for resources is much smaller than the ecological footprint of those countries.

Ecological Footprint | WWF. To put it simply, ecological footprint is the result of human activity and is determined by the amount of biologically productive land and water needed to create the commodities we use and to ingest the garbage we make.

The quantity of resources a person uses and the amount of garbage they generate that must be filtered out by the environment's biogeochemical cycles are examples of ecological footprints. The biocapacity of the planet, for instance, equates to around 1.7 world hectares of fertile land per person.
