Many male birds will expend A great deal of energy building nests. Females will mate with the males who build the best nest. This is best described as an example of ___.
a) natural selection
b) sexual selection
c) runaway selection
d) an invasive species
e) disruptive selection
Answers
Answer:
B
Explanation:
Female birds mate with the males who build the best nest is the example of option b. sexual selection.
Sexual selection is a mode of natural selection in which one sex members choose the mate with the member of the other sex for mating.
These members of the biological sex prefer opposite sex members for species-specific characteristics in individuals of the other sex such as best building nest in birds. Other male birds compete with members of the same sex to get selected by members of the female birds in this instance.Thus, the correct answer is option b. sexual selection as female birds prefers species-specific traits to select their mating partner by best nest building by males.

When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? Two diverged populations are capable of mating and producing viable and fertile offspring. Hybrid individuals may have reduced fitness and thus be strongly selected against. Hybrid individuals are always allopolyploid and are thus unable to mate with either of the original species. One species has a selective advantage, so as hybridization continues, the other species will go extinct.
Answers
Answer:
Two diverged populations are capable of mating and producing viable and fertile offspring.
Explanation:
Although the biological concept of species says that two different species can not mate and produce viable fertile descendants, the hybrid zones are characterized for being an area where two different genetically groups meet and reproduce. These groups might be the same or different species.
This is a frequent phenomenon in nature, and widely common geographically and among taxonomic groups. It is not rear that different sympatric populations, with a short time of divergence and similar reproductive strategies, can hybridize and even generate new populations that get reproductively isolated from their parentals.
When talking about sympatry we refer to two similar species that coincide in part or their whole distribution area.
These new populations are even morphologically different from the parental forms, which allow them to colonize new habitats and niches, promoting diversification.
Hibridation zones are very important to conserve, just because they are points of genetic diversity generation and diversification areas.
When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals can form. This is possible because hybrid individuals are always allopolyploid and therefore are unable to mate with any of the original species, to understand more we need to know that......
Hybrid animalsHybridization, that is, the process through which different species reproduce, generating an offspring, is not considered a very common phenomenon in nature. This is because, in general, species have a distinct number of chromosomes, the cell structures that contain genes. These differences in the number of chromosomes can make the development of the embryo unfeasible, as the alignment of equivalent chromosomes from the female and the male are necessary for the division of the fertilized cell to occur. When this alignment does not occur, the cell does not reproduce and dies. However, in some cases, even with the lack of chromosome pairs, reproduction between different species is successful, generating the hybrid. However, the birth of the individual does not mean that its survival is guaranteed. Often, the hybrid generated is weaker than its parents and does not survive; in other cases, the hybrid can adapt better to the environment than the species that conceived it.
With this information, we can conclude that hybrid animals are a cross between two different species, but this hybrid can have several complications for its survival.

D. It provides evidence of links between evolutionary species.
E. It provides scientists with a reason to continue their research.
Answers
Answer: D. It provides evidence of links between evolutionary species.
Explanation: The significance to scientists of finding a new, unknown fossil is that it provides evidence of links between evolutionary species.
Organisms arose as a result of these changes, and some of their remains have been preserved as fossils. An organism's type, life history, and preservation method can all be ascertained by studying a fossil. Thus, option D is correct.
What are the features of finding a new, unknown fossil?They can discover when and how various animals existed millions of years ago by studying fossils. Fossils can sometimes show scientists how the Earth has changed over time.
The discovery of a new, undiscovered fossil is significant to scientists because it shows connections between evolutionary species.
Fossils with remarkably similar geometries are thought to be from the same species. It is considered that fossils with somewhat differing geometries come from a separate species. Usually, the fossil species has been researched and given a name.
Therefore, It provides evidence of links between evolutionary species.

At temperatures higher than the maximum growth temperature for an organism:
a. proteins are permanently denatured. membranes become too fluid for proper function.
b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Answers
Answer:
The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Explanation:
The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.
When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.

When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.

Why vertical farming is important?It has been said to be the future of agriculture in the UAE since they huge amount of goods and have to find ways to be self sustaining by boosting local production. Apart from being self sustaining, they also aim to provide safe and nutritious food.
The vertical garden is an agriculture concept for growing plants inside buildings or multi-story skyscrapers, often called farmscrapers, a term derived from the English skyscraper. In these buildings, which would function as large greenhouses, agriculture involves the use of technologies such as hydroponics to aid in plant growth. Some projects include the practice of livestock (especially poultry) on the lower floors.

Answers
Answer:
The given blank can be filled with a venule.
Explanation:
A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.
The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.
