Therefore it is a representation of the role of photosynthesis in transferring the carbon from atmosphere to the biosphere.

Natural selection is the most likely determine if a mutation will become an adaptation in a species.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.

Natural selection occurs only if there is both :

Therefore, natural selection it's a way of selecting organisms with certain traits that's driven completely by nature compared to 'artificial selection' such as when humans breed sheep to become more wooly and more tame by deliberately cross breeding and selecting for desirable to humans traits.

Genetically modified foods have both advantages and disadvantages for human health, the environment, and the economy.

Genetically modified (GM) foods are those derived from organisms for whom the genetic material (DNA) has indeed been altered in ways that do not occur naturally, such as the introduction of a gene from another organism. The technology is frequently referred to as "modern biotechnology" or "gene technology," and it is also referred to as "recombinant DNA technology" or "genetic engineering" at times.

Currently available GM foods are mostly derived from plants, but foods derived from GM microorganisms as well as GM animals seem to be likely to come on the market in the future. Most existing genetically modified crops have indeed been developed to increase yield by introducing resistance to plant diseases or increased herbicide tolerance. GM foods can also help to lower food prices by improving yields and reliability.

Kangaroos popularized the trampoline 30 years after its invention. Trampolines have been around for quite some time now. It was created by an American gymnast named George Nissen in the 1930s.

It was only in 1955 that he patented the idea of the trampoline.In the 1950s, Nissen saw kangaroos bouncing around a trampoline at a traveling circus in the USA. It was then that he realized that he could use the trampoline as an entertainment tool. Therefore, he began to promote trampolining as a new sport to introduce gymnastics to the public.The word trampoline was derived from the Spanish word trampolin, which means springboard. With the development of this exciting sport, trampolining was introduced to the Olympics in 2000.

Trampolining is now a popular activity in many parts of the world, particularly in gyms, schools, and amusement parks.To conclude, Kangaroos popularized the trampoline 30 years after its invention.

The genetic distance is calculated as the percentage of differing nucleotides between two species at a specific locus.

Genetic distance is a measure of the evolutionary divergence between two species. It is determined by comparing the nucleotide sequences at a specific genomic locus in both species. The number of nucleotides that differ between the two sequences is counted, and this value is expressed as a percentage of the total number of nucleotides examined.

For example, if two species have a nucleotide difference of 5 out of 100 at a particular locus, the genetic distance would be 5%. This metric provides insights into the genetic variation and evolutionary relationships between species. A higher genetic distance indicates greater genetic divergence and implies a longer period of evolutionary separation between the species.

By quantifying genetic differences, researchers can understand the genetic relationships between species, track evolutionary changes, and study population genetics. Genetic distance calculations are commonly used in various fields such as evolutionary biology, phylogenetics, and conservation genetics to explore genetic diversity and evolutionary patterns among different organisms.

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

When dextran is injected into the blood, anionic dextran is preferentially blocked by the glomerulus. The glomerular capillary wall has a negative charge, which repels negatively charged molecules.

Anionic dextrans carry a negative charge and are repelled by the glomerulus, leading to their preferential excretion through urine. Neutral and cationic dextrans, on the other hand, are not repelled by the glomerulus and can pass through easily.

Therefore, anionic dextrans are commonly used as markers to measure glomerular filtration rate (GFR). By measuring the excretion rate of anionic dextrans, it is possible to determine the GFR, which is an important measure of kidney function.

Answer:

In the past, there were various pieces of evidence that were used to dispute the idea of continental drift, which is the theory that suggests that continents have moved over time. These pieces of evidence were put forward by scientists who did not believe in the concept of continental drift.

Explanation:

Here are a few examples:

Lack of Mechanism: One argument against continental drift was the lack of a known mechanism that could cause the continents to move. Scientists questioned how continents, which are large land masses, could shift and change their positions without any clear explanation.

Fixed Continents: Another argument was that continents seemed to be fixed in their positions. Scientists believed that the continents were immovable and had always been in their current locations. They argued that the shapes of the continents fit together like puzzle pieces simply because they happened to look that way, not because they were once connected.

Gravitational Forces: Some scientists proposed that gravitational forces were responsible for the arrangement of continents. They suggested that the distribution of land masses on Earth was due to variations in gravity, rather than the movement of the continents themselves.

Geological Stability: The stability of the Earth's crust was also used as evidence against continental drift. Scientists believed that the Earth's crust was rigid and could not undergo significant movements or changes in shape.

However, over time, new evidence emerged, such as the discovery of mid-ocean ridges and magnetic anomalies, which supported the theory of continental drift. This led to the development of the theory of plate tectonics, which explains how the Earth's lithosphere (crust and upper mantle) is divided into several large plates that move and interact with each other, causing continental drift and other geological phenomena.

Variation in the number as well as the types of molecules within the cells basically provides the organisms more amount of ability in order to survive as well as reproduce in different environments.

Variation which is present at the molecular level basically provides the said  organisms with different types of abilities to be able to respond to a number of different types of environmental stimuli and it therefore gives them a selective advantage.

Some of the examples are decoupling proteins as well as the heat production in the endotherms, compartmentalization of the cells etc. Another example of selective advantage is evident if we see how much more amount of chemical energy is basically produced in the case of eukaryotes which have a mitochondria with respect to prokaryotes that ferment.

The type of muscular contraction that occurs when there is muscular tension but no change in muscle length is known as an isometric contraction.

Isometric contractions occur when the muscle produces tension without changing its length. These types of contractions are commonly used in isometric exercises like planks, wall sits, and static holds in weightlifting. Isometric contractions do not cause the muscle to move and are commonly used for stability, balance, and control.

During an isometric contraction, the muscle fibers are activated, and the tension within the muscle increases, but there is no change in muscle length. Examples of activities that require isometric contractions include pushing against an immovable object like a wall, holding a yoga pose, or maintaining good posture.

The transcribed strand in DNA is "5' to 3' sense." (Option A)

The transfer of genetic material from DNA to RNA is known as transcription. The DNA double helix separates during transcription, allowing the RNA polymerase enzyme to transcribe a single DNA strand. The resulting RNA molecule is single-stranded, and it has a sequence of nucleotides that are complementary to one of the DNA strands. RNA polymerase recognizes the sequence of nucleotide bases on the DNA molecule that signifies the start of a gene and binds to it.

The transcription occurs in a particular direction, that is, it begins at the promoter and ends at the terminator. In transcription, the enzyme RNA polymerase reads the DNA sequence and synthesizes RNA in the 5' to 3' direction. The RNA synthesized during transcription is referred to as the primary transcript and is then modified and processed to become a functional RNA molecule.

Thus, the correct option is A.

A pea plant has a purple allele (i.e., purple is a dominant trait) while and a white allele (i.e., white is a recessive trait), meaning it has a heterozygous genotype.

This means that the plant carries two different alleles for the same gene. In this case, the alleles are for color: purple and white. A heterozygous genotype will not always produce an intermediate phenotype; instead, it can produce either of its two possible phenotypes: purple or white.

This is because one of the two alleles always dominates over the other when they are present on one chromosome together in a heterozygous genotype. Since purple is dominant over white, it will always be expressed in this particular case.
