Jose and Rema are making sourdough bread. They have been feeding the starter dough for a week now, and it has undergone lactic acid fermentation. They mix the dough and add a portion of the starter, which will give the bread its famous texture and sour flavor. What process will occur next to make the dough rise?
A
Alcoholic fermentation takes place and ethyl alcohol and CO2 gas are formed, creating pockets in the dough.
B
Alcoholic fermentation takes place, and the yeast give off oxygen, creating pockets in the dough.
C
Alcoholic fermentation takes place, and during the Krebs cycle, CO2 is produced, creating pockets in the dough.
D
Alcoholic fermentation takes place, and the H2O byproduct of the electron transport chain vaporizes to create pockets in the dough.
Answer:
A. Alcoholic fermentation takes place and ethyl alcohol and CO2 gas are formed, creating pockets in the dough.
Explanation:
Alcoholic fermentation is a process carried out by certain organisms in the absence of oxygen. In this process, sugars such as glucose etc are broken down without oxygen into ethanol (alcohol) and carbon dioxide (CO2) by an organim called YEAST.
According to this question, Jose and Rema are making sourdough bread. The starter being fed has undergone fermentation (in the absence of oxygen). This means that the organism undergoing the fermentation produces ethyl alcohol and CO2 gas, creating pockets in the dough. Hence, making the dough to rise.

Are eukaryotes more closely related to bacteria or to archaea? Explain.
Hello!
The Answer Is: Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.Thank you for asking this question!

Which of the following actions will provide a negative control for the investigation?
Repeating the experiment at 25°C
Repeating the experiment at 25°C
Repeating the experiment using twice the amount of hydrogen peroxide
Repeating the experiment using twice the amount of hydrogen peroxide
Repeating the experiment using twice the amount of peroxidase
Repeating the experiment using twice the amount of peroxidase
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.

Which statement describes an advantage of sexual reproduction over asexual reproduction?
Answer:
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.
What is sexual reproduction?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.

Carbon is stored in leaves in various forms, such as sugar. When leaves
decay, they lose mass. Which of the following sentences explains what
happens to the carbon that is stored in leaves when they decay? *
The carbon is destroyed as the leaves decompose
The carbon evaporates
The carbon is converted into nitrogen by bacteria in the soil
The carbon is converted into carbon dioxide and released into the atmosphere
Answer:
D.The carbon is converted to carbon dioxide and released into the atmosphere
Explanation:
When the water availability of a plant's environment decreases, the plant can respond by closing its stomata. This reduces the amount of water that the plant loses through its leaves due to transpiration. Closing the stomata also reduces the amount of carbon dioxide that the plant can take in through its leaves, which will most likely result in A. a decreased rate of photosynthesis. B. no change in the cellular processes of the plant. C. an increased rate of photosynthesis. D. an increased rate of cellular respiration.
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.

Three that live in the savanna are lions, giraffes, and elephants. Choose two of these animals. For each one, describe an adaptation that has enabled it to survive in the savanna. Then tell which which animals in the population would be more likely to survive if a dry season was unusually long.
Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.

If Earth did not rotate and there were no Coriolis effect, surface wind
direction would primarily be *
From east to west
From west to east
From the poles to the equator
O From the equator to the poles
If Earth did not rotate and there was no Coriolis effect, the surface wind direction would primarily be from the poles to the equator.
What do you mean by the Coriolis effect?
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.
