A gene is a section of dna that either creates a functional product, often a(n) polypeptide, or functions as a unit of heredity that influences the phenotypic of an organism.

An area of DNA called a gene codes for a useful product (mRNA, tRNA, or rRNA). Most genes code for protein synthesis because the great majority of genes are transcribed into mRNA, which is then translated into polypeptides or proteins.

Genes are pieces of genetic data that organisms pass on to future generations. For the creation of proteins that give cells their ability to operate, genes carry coded information. The whole set of genes in an organism is referred to as its genome. There are between 20,000 and 25,000 genes in the human genome.

Answer:

The purpose of natural selection is not a conscious or intentional one, as it is not driven by a specific goal or purpose. Instead, natural selection is a fundamental process in biology that acts on heritable traits within populations over generations. It is a key mechanism of evolution.

Explanation:

The primary outcome of natural selection is the adaptation of organisms to their environment. Individuals with traits that are advantageous in a particular environment are more likely to survive, reproduce, and pass on those beneficial traits to their offspring. Conversely, individuals with traits that are disadvantageous are less likely to survive and reproduce, leading to a reduction in the frequency of those traits in the population over time.

Natural selection, therefore, acts as a filter that shapes the characteristics of populations, favoring traits that enhance an organism's survival and reproductive success in a given environment. Over many generations, this process can lead to the development of new species or the modification of existing ones, as populations accumulate adaptations that allow them to thrive in different ecological niches.

It's important to note that natural selection does not have an end goal in mind, nor does it necessarily lead to the "best" or most advanced organisms. Instead, it is a consequence of the interactions between organisms and their environment, constantly shaping and refining the traits of living beings based on their ability to survive and reproduce.

Explanation:

The vertebrate forelimb of human, bird, and bat may not appear to have much in common, but a closer examination of the anatomy shows that the same bones were applied to a variety of different jobs in each of these species. Evolution doesn't plan ahead. It can only work with what's available. The color coding shows the way the bony elements were modified in each species. You might think that the two wings would be more similar in design because of the job they do but, in fact, the bird wing and human arm are more similar on the interior. However, the bird "hand" is reduced, whereas the bat and human hand have more in common. See if you can find a similar image of a dolphin or whale flipper for another comparison.

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure \(\PageIndex{3}\) shows the upper appendages of several different mammals. They all have the same basic pattern of bones, although they now have different functions. All of these mammals inherited this basic bone pattern from a common ancestor.

Answer:

Non renewable resources such as coal, oil and natural gas contribute to air pollution, water pollution and global warming.

Explanation:

Non-renewable energy sources are the energy sources that do not naturally replenish themselves. At some points in the nearest future, their sources would be become depleted.

Non-renewable energy sources such as coal, crude oil and natural gas contribute to the pollution of the environment in varying degrees. They require burning and this process leads to the release of gases such as carbon dioxide, carbon monoxide, oxides of sulfur and nitrogen,methane, water vapor, etc.

The released gases often posses different threats to organisms in the environment at certain level, constituting what is known as environmental pollution. Some of them dissolve in rain water to cause acid rain, some are directly poisonous when inhaled by living organisms, while a host of the pollutants absorb radiation from the sun and cause the warming of the planet, a phenomenon known as global warming.

Crude oil spillage or that of the any of its derivatives cause various environmental problems. They are poisonous to aquatic lives and render water useless for humans.

Explanation:

The Frye and Edidin experiment demonstrated that lateral protein movement within the cell is affected by temperature.

The Frye and Edidin experiment, conducted in 1970, utilized fluorescence recovery after photobleaching (FRAP) to demonstrate that lateral protein movement within the cell membrane is influenced by temperature and membrane fluidity.

In this experiment, cell membranes were labeled with fluorescent markers, and a specific region of the membrane was photobleached (rendered non-fluorescent) using a focused laser beam. As time progressed, fluorescent molecules from surrounding areas diffused into the bleached region, leading to the recovery of fluorescence. The rate of fluorescence recovery provided insights into the lateral movement of proteins within the membrane.

The temperature affects membrane fluidity, altering the movement of lipid molecules and proteins within the membrane. Higher temperatures increase the kinetic energy of molecules, resulting in greater membrane fluidity and faster lateral movement of proteins. Conversely, lower temperatures decrease fluidity and slow down lateral movement.

By conducting the experiment at different temperatures, Frye and Edidin demonstrated that lateral protein movement is indeed influenced by membrane fluidity, which, in turn, is affected by temperature. This experiment highlighted the dynamic nature of cell membranes and the role of lipid-protein interactions in regulating membrane properties.

Overall, the Frye and Edidin experiment provided valuable insights into the biophysical properties of cell membranes, contributing to our understanding of how the arrangement and movement of molecules within the membrane influence cellular processes.

Answer:

Vascular plants, also known as tracheophytes, are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant.

1. These lignified tissues are also called vascular tissue and consist of water-conducting xylem tissue and food-conducting phloem tissue.

2. Vascular tissue forms a central column, also called stele, through the plant axis for the transport of different substances.

3. Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues.

4. The root is a true root that enables the plant to anchor onto the soil and gets nutrients from it.

5. The leaves are broad and have stomata that work for gas exchange and support transpiration.

6. The stem of vascular plants is multilayered with vascular tissue that helps in the protection and conduction of food and water.

7. The arrangement of these issues might be different in a different group of plants as it depends on the pattern of division of cells.

8. The xylem is composed of non-living matter, tracheids, and vesicles, hardened by lignin that provides a stiff structure to the tissue. 9. The phloem, on the other hand, contains living sieve elements that are not lignified.

10. Vascular plants are capable of surviving on land due to their ability to transport food, water, and mineral to different parts of the plant by creating pressure through the tissues.

11. Besides, they also have several modifications that facilitate their survival on land.

12. Another essential characteristic of vascular plants is that the principal generation phase in these plants is the sporophytic phase where they produce diploid spores.

13. Vascular plants are tall and large in size compared to the non-vascular plants because of their ability to transport necessary substances to all parts of the body via vascular tissue.

14. It is believed that vascular plants are a more evolved version of non-vascular plants and thus came later in the evolutionary history.

15. Vascular plants are divided into two groups; non-seed plants or lower vascular plants or cryptograms and seed plants or higher vascular plants or phanerogams.

16. The lower vascular plants include plants like ferns that although are adapted to survive on land still have some characteristics of their aquatic ancestry. These plants belong to the group Pteridophyta.

17. The higher vascular plants are numerous and extremely diverse and are further divided into different subgroups.

18.Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses, etc.
