The question is incomplete, the complete question is;

Researchers investigated the influence of environmental pH on the activity of peroxidase, an enzyme that catalyzes the conversion of hydrogen peroxide to water and oxygen gas. In an experiment, the researchers added a hydrogen peroxide solution containing guaiacol to several identical test tubes and adjusted the solution in each test tube to a different pH. The researchers included the guaiacol because it caused the solutions to change color as the reactions proceeded, which the researchers relied on for measuring reaction rates. Finally, the researchers added the same amount of peroxidase to each test tube and measured the rate of each reaction at 23°C. The results of the experiment are represented in Figure 1.

Figure 1. The effect of pH on peroxidase activity

Which of the following actions will provide a negative control for the investigation?

A

Repeating the experiment at 25°C

B

Repeating the experiment using twice the amount of hydrogen peroxide

C

Repeating the experiment using twice the amount of peroxidase

D

Repeating the experiment using heat-denatured peroxidase

Answer:

D

Repeating the experiment using heat-denatured peroxidase

Explanation:

A Negative control is a situation in which a particular reagent added to an experimental set up just as all the other samples is not expected to effect any change in the responding variable.

In this case the independent variable is the pH of the solution while the responding variable is the activity of peroxidase enzyme.

A denatured enzyme is not expected to have any effect on the responding variable. Hence, this is a negative control.

The action that will give a negative control for the investigation is D. Repeating the experiment using heated-denatured peroxide.

A negative control simply means the situation where a reagent that is added to an experimental set up is not expected to have an impact on the responding variable.

It should be noted that repeating the experiment at 25°C will not lead to a negative control for the investigation. On the other hand, the repetition of the experiment using heated-denatured peroxide will lead to a negative control as the responding variable isn't affected.

Answer:

about the Trilobites is =Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[4][5] meaning "three lobes") are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.[6] . and about the algae is =Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.

Answer:

If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.

There would be no  negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.

Hope it help!

There would be more carbon dioxide, which would eventually burn away the ozone layer, as well as no oxygen, and all animal and plant life would perish.

The biosphere is basically comprised up of the areas of the Earth where life can be found.

The biosphere encompasses all the things from the deepest tree root systems to the dark environment of ocean trenches, including lush rainforests, and high mountaintops. Earth is described by scientists in terms of spheres.

Because it is all of life, the biosphere is as important as life itself. Earth would be a lifeless planet like Mars or Venus without the biosphere. Human insecurity grows as natural resources are depleted.

The biosphere is the zone that contains all living things. The biosphere requires the lithosphere, hydrosphere, and atmosphere to exist. There would be no life on Earth if these three spheres did not exist.

Thus, this way, the atmosphere would be impacted in the absence of the biosphere.

One advantage is that secual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

Explanation:

One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

When sperm from a male parent fertilizes an egg from a female parent during sexual reproduction, the result is an offspring that is genetically distinct from both parents.

The genetic diversity of organisms is a result of sexual reproduction. Meiosis, a process that creates sperm and egg cells, is the first step in sexual reproduction.

Because they have half as many chromosomes as the parent, these cells are known as haploids. A diploid zygote is created during sexual reproduction when a male parent's haploid sperm fertilizes a female parent's haploid egg.

Therefore, One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

Hola, para resolver tu problema debes tener en cuenta tanto a tu gata como a sus crías.

Primero, respecto a la madre, una buena alternativa serian inyecciones de vitaminas y suero, que la ayudarían a reponer energías y a generar más alimento para sus crías. Pero también la ayudaría a sentirse menos decaída, lo cual mejoraría su estado de ánimo.

Por el lado de las crías, si lo que deseas es que se alimenten por otra vía que no sea la de su madre, una alternativa ideal es la leche maternizada artificialmente, que es un alimento específico para gatos recién nacidos, aunque es bastante costoso de adquirir. Otra alternativa, ya casera, es hervir arroz, colar los granos y utilizar el agua en donde se cocinó como alimento para los cachorros. Obviamente, debes dejar enfriar el líquido, pero una vez a temperatura natural tendrá muchos nutrientes que habrá absorbido de los granos de arroz y servirá como sustituto de la leche materna.

Answer:

similar results in multiple tests of the claim

Explanation:

e2020 told me so

Similar results in multiple tests of the claim are a factor found in a scientific claim.

The statements made regarding an issue in the field of science are referred to as a scientific claim. Scientific claims are different from any other form of a claim as they are made after a lot of research and are backed by data.

Science is basically a systemically done study of the world around us. People practising in the field of science are called scientists. They collect data, analyze it and based on this analysis they come to conclusions.

Thus a scientific claim is a statement made after coming to the conclusion after analyzing the data.

Even though, a scientific claim is made after thorough research, not every scientific claim is as reliable. The experimentation and analysis can be subject to various errors which can cause a faulty scientific claim.

Therefore, the factor present in a scientific claim would be similar results in multiple tests of the claim.

Answer:

A. a decreased rate of photosynthesis.

Explanation:

Stomata is a structure in the leaves of higher plants, which they use majorly for the purpose of gas exchange. However, the process whereby plant loses water called transpiration also occurs via the stomata. In a situation whereby the availability of water in a plant's environment is low, the plant responds by closing its stomata in order to conserve water (reduce the amount of water that the plant loses through its leaves due to transpiration).

Closing the stomata by plants means not allowing ample carbon dioxide (CO2), which is needed for the process of photosynthesis to occur, to enter the plant. This will most likely result in a DECREASED RATE OF PHOTOSYNTHESIS.

Answer:

D.The carbon is converted to carbon dioxide and released into the atmosphere

Explanation:

If Earth did not rotate and there was no Coriolis effect, the surface wind direction would primarily be from the poles to the equator.

The Coriolis effect may be defined as making things traveling long distances around the Earth appear to move at a curve as opposed to a straight line.

The Coriolis effect is responsible for the blowing of winds from the east to the west. It makes the wind system twist counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Without its presence, the direction of wind gets opposed.

Therefore, if Earth did not rotate and there was no Coriolis effect, the surface wind direction would primarily be from the poles to the equator.
