which structure of the plants are an opening that exchange gas and water?
A: stromal lamellae
B: grana
C: stomata
D: stroma
Answers
The structure of the plants that are opening that exchange gas and water is stomata. The correct option is C: stomata.
Stomata are tiny pores on the epidermis of a plant leaf that allow gas exchange. They are mostly found on the lower side of the leaf, although some plants, such as succulents, have stomata on their stems. They regulate the flow of gases in and out of the leaf, including oxygen, carbon dioxide, and water vapor. Stomata open to also draw carbon dioxide from the atmosphere in order for the process of photosynthesis to occur. They play an important role in the photosynthesis and transpiration of plants.

In photosynthesis, the carbon in CO2 is initially fixed to what molecule?
O G3P
O NADPH
O RuBP
O ATP
Answers
In photosynthesis, the carbon in \(CO_{2}\) is initially fixed to the molecule RuBP (ribulose-1,5-bisphosphate).
The process of carbon fixation is a crucial step in photosynthesis, where carbon dioxide (\(CO_{2}\)) is converted into organic molecules. This process occurs in the stroma of the chloroplasts in plant cells. The primary molecule involved in carbon fixation is RuBP, which stands for ribulose-1,5-bisphosphate.
RuBP serves as the acceptor molecule \(CO_{2}\) during the initial stages of carbon fixation. The enzyme responsible for this reaction is called rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase). Rubisco catalyzes the reaction between \(CO_{2}\) and RuBP, resulting in the formation of an unstable intermediate compound. This compound then breaks down into two molecules of 3-phosphoglycerate (3-PGA).
3-PGA is subsequently converted into glyceraldehyde 3-phosphate (G3P), which is a key intermediate in the synthesis of glucose and other carbohydrates. G3P can be further utilized in various metabolic pathways to produce sugars, starches, and other organic compounds necessary for plant growth and energy storage.
While NADPH and ATP play critical roles in the overall process of photosynthesis, they are not directly involved in the initial carbon fixation step. They are generated during light-dependent reactions and are used in subsequent steps of photosynthesis, such as the reduction of 3-PGA to G3P.

select all of the following molecules whose functions are pro-apoptotic (function to increase the likelihood that apoptosis will occur). group of answer choices
- IAP
- Bad
- Bcl-2
- Cytochrome c
- Bax
- Fas
- Bak
- SMAC/DIABLO
Answers
The molecules Bad, Bax, Fas, and SMAC/DIABLO are pro-apoptotic, meaning they function to increase the likelihood that apoptosis will occur.
Apoptosis, also known as programmed cell death, is a tightly regulated process that eliminates unwanted or damaged cells in multicellular organisms. Various molecules play a role in either promoting or inhibiting apoptosis. Among the given options, the molecules Bad, Bax, Fas, and SMAC/DIABLO are pro-apoptotic, meaning they promote or enhance the occurrence of apoptosis.
Bad is a pro-apoptotic molecule that inhibits the anti-apoptotic protein Bcl-2 and its family members, thereby promoting apoptosis. Bax is another pro-apoptotic member of the Bcl-2 protein family that triggers the release of cytochrome c from mitochondria, initiating the apoptotic cascade. Fas, also known as CD95, is a cell surface receptor that, when activated by its ligand, triggers a signaling pathway leading to apoptosis. SMAC/DIABLO is a mitochondrial protein released during apoptosis that antagonizes the activity of inhibitors of apoptosis proteins (IAPs), promoting cell death.
On the other hand, Bcl-2 and Cytochrome c are not pro-apoptotic molecules. Bcl-2 is an anti-apoptotic protein that inhibits apoptosis by preventing the release of cytochrome c from mitochondria. Cytochrome c, a component of the electron transport chain in mitochondria, is released into the cytoplasm during apoptosis, but its function is not directly pro-apoptotic.
In summary, the molecules Bad, Bax, Fas, and SMAC/DIABLO are pro-apoptotic, promoting the likelihood of apoptosis occurring, while Bcl-2 and Cytochrome c have functions that are not pro-apoptotic.

A. Phytoplankton have the largest population size because light is an unlimited resource, so there is little competition with mangroves for light.
B. Mangroves have the largest population size because trees are closer to the source of light than are phytoplankton.
C. Prawns have the largest population size because there is no competition for phytoplankton in the community.
D. Herons and pelicans have the largest population size because they are top predators in the community.
Answers
A. Phytoplankton have the largest population size because light is an unlimited resource, so there is little competition with mangroves for light.
In a food web, the primary producers, such as phytoplankton, typically have the largest population size as they are the base of the food chain. They are autotrophs that convert sunlight into energy through photosynthesis. While mangrove trees also photosynthesize, their role in the food web is different, and their population size is usually smaller than that of phytoplankton. As phytoplankton are abundant in the water, they have access to sunlight without directly competing with mangroves for light.

The dose of visions needed to KILL 50% of host organisms is called the ___
Answers
The dose of visions needed to KILL 50% of host organisms is called the LD50.
What is LD50?
The term LD50 is a measure of toxicity of a substance.
LD50 is an acronym for “lethal dose 50%” or “median lethal dose.” It refers to the dose of a substance that is expected to cause death in 50% of the exposed organisms. LD50 is usually calculated in milligrams of substance per kilogram of body weight in animal testing.
The LD50 test is typically conducted by administering increasing doses of a substance to a group of test animals and observing the effects. The dose-response relationship is determined by recording the number of deaths at each dose level. The LD50 value is then calculated as the dose at which 50% of the animals in the test population die.
LD50 values are important in toxicology because they provide a measure of acute toxicity for a substance. They are used to compare the relative toxicities of different substances and help in determining safe levels of exposure for humans and other organisms. It's important to note that LD50 values are typically determined through animal testing and are not directly applicable to humans, as different species may have different sensitivities to various substances.

the counterclockwise rotation of flagella propels a bacterium forward through a solution. What happens if the bacterium reverses the direction of rotation
Answers
If a bacterium reverses the direction of rotation of its flagella, it will change the direction of its movement.
Flagella are whip-like structures that extend from the surface of bacteria and are responsible for their movement. When flagella rotate counterclockwise, they form a bundle that propels the bacterium forward. However, if the direction of rotation is reversed, the flagella become disorganized and the bacterium will change direction. This reversal of direction is caused by a switch in the rotation of the flagellar motor proteins, which control the movement of the flagella. The ability of bacteria to change their direction of movement is important for their survival, as it allows them to navigate towards or away from certain stimuli, such as nutrients or toxins.
