Answer: The function allows dna to copy itself

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer:

It happens because the leaves trap the sunlight energy

Explanation:

When the leaves trap this sunlight energy and combines with the carbon dioxide and water it goes through photosynthesis. This turns the sunlight energy and other resources it collects to energy (sugars) that the plant will use to grow and support itself. It then releases oxygen as a waste which is what humans use. We exhale carbon dioxide that the plants need so while they help us we also help them.

LUSTER

Explanation:

The physical property of the metals that make them shiny is called Luster. Therefore, Aliyah was able to polish the metals like silver, copper, and gold.

Luster is one of the important physical properties of the metals, which refers to the way light is reflected from the surface of the metal. In the context of metal, luster refers to the shininess or brightness of the metal surface.

The luster of a metal ranges from dull to very shiny and can influence the perceived value of the metal as well as its suitability for various applications.

The luster of a metal can be affected by factors such as surface roughness, impurities, and exposure to environmental conditions such as corrosion and oxidation.

A change in temperature for a steel wire causes it to expand or contract, depending on whether the temperature increases or decreases, respectively.

A change in temperature affects the steel wire by altering its physical properties. Steel is known for its high thermal conductivity, which means it can quickly conduct heat energy. When the temperature of the wire increases, the individual steel atoms and their constituent particles gain kinetic energy, causing them to vibrate more vigorously.

This increased motion leads to an expansion of the wire as the atoms move farther apart. Conversely, a decrease in temperature reduces the kinetic energy, causing the atoms to move closer together, resulting in contraction.

The magnitude of the temperature change determines the extent of expansion or contraction in the steel wire. Steel has a coefficient of thermal expansion, which quantifies how much it expands or contracts per degree of temperature change. This coefficient varies depending on the specific type of steel and its alloy composition.

It's crucial to consider the change in temperature when working with steel wires in applications such as construction, engineering, or electrical systems. The expansion or contraction can impact the wire's length, dimensions, and overall structural integrity. Engineers and designers must account for these temperature-induced changes to ensure the steel wire and its surrounding components can withstand the expected temperature variations without compromising functionality or safety.

Two possible consequences of the release of these turtles into Gulf waters, including the effect on native turtle species are

An invasive turtle species poses direct competition with native turtles within Gulf of Mexico, resulting in possible shrinkage in population sizes for the latter group. Resource scarcity driven primarily by competition over access to nests, habitats and food sources can render natives less effective at these activities compared to their new rivals.

Furthermore, identifying underlying consequences triggered by invasive species' potential alteration of ecosystem dynamics (eg: substantial loss or balanced gain) remains crucial for further consideration. The issue of climate change represents an imminent danger that threatens the well-being of our planet. Swift action from all corners of society is required, including private citizens, companies, and governing bodies across national borders.

Answer and Explanation:

In current years the subject of inherited disorders in pedigree dogs has been extensively discussed. This article discussed the consequences related to repeat breeding of pedigree dogs. In the last few years several pedigree breeds have been generated which depend on the selection of particular behavioral and physical features. The development of pedigree dog breeds can be both a curse and a blessing. The desired characteristics are severely taken, while undesired characteristics can be unintentionally secure within the breed. The repeated breeding of purebred dogs lead the loss of genetic diversity.  The loss of genetic diversity can be attributed to two major actions; the first one happening in domestication and the second arising from the development of breed. Where the repeated use of line breeding, popular sires, promotion of breed barrier rule and breeding for particular phenotypic traits contributed to loss of genetic variation. Widespread use of a popular sires leads to overrepresentation of that dog’s genome in breed. Overrepresentation of a popular sires genome increase the risk of monogenetic inherited disorders. According to the other article inbreeding causes severe birth abnormalities and defects such as epilepsy, and heart diseases that could make the lives of animals miserable. These problems start in the 19th century, when dog fanciers activated to set down desired physical characteristics. The scientific evidence shows that ninety percent dogs are said to be healthy. According to the both articles repeated breeding of pedigree dogs cause many genetic disorders.

Answer:

A veterinarian wrote an article stating his disapproval of some of the tactics used to breed pedigree dogs. He stated that pedigree dogs can be healthy, but because of inbreeding, they’re more likely to have health problems than other dogs. The author supported his statement with scientific studies.

A breeder with 20 years of experience wrote an article that was pro-breeding. He talked about his own success and shared his opinions on proper breeding techniques. Because the veterinarian used scientific facts to support his reasoning, his article seemed more scientifically credible to me.

A bacterium that can develop close to the lower part of a cylinder loaded up with fluid media ought to be delegated anaerobic.

Sometimes, liquid media are referred to as "broths," such as nutrient broth. Bacteria grow uniformly in a liquid medium, resulting in general turbidity. It is known that certain aerobic bacteria and those with fimbriae (Vibrio and Bacillus) grow as a thin film called a "surface pellicle" on the surface of broth that has not been disturbed.

liquid medium containing various indicators and nutrients. allows for the growth of a lot of bacteria, and the amount of growth can be measured by how turbid (cloudy) the culture is. Using a loop, bacteria are introduced into the broth.

Nutrient agar, tryptic soy agar, and brain heart infusion agar are all examples of standard general-purpose media that can help a wide range of bacteria grow. A medium might be enhanced, by the expansion of blood or serum.

The most likely explanation here is that mitochondria was once a prokaryotic organism. The correct option is A.

Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).

The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).

Mitochondria are special compartments (organelles) in our cells best known for their role as powerhouses, converting food molecules into ATP, a molecular fuel for the rest of the cell.

Mitochondria and chloroplasts most likely evolved from engulfed prokaryotes that were once self-contained organisms.

At certain point, an aerobic prokaryote was engulfed by a eukaryotic cell, which then formed an endosymbiotic relationship with the host eukaryote, eventually developing into a mitochondrion.
