Bacteria can be killed by an antibiotic unless they carry a plasmid that has the gene for resistance to that antibiotic. (Scientists call these kinds of genes selectable markers; only bacteria that carry this gene will survive exposure to an antibiotic.) If the uptake of DNA by bacteria is inefficient (as discussed in the reading), why is a selectable marker critical in cloning a gene in bacteria?

D) THICK WAXY CUTICLE

The leaf have adaptations in order to do gas exchange, which are the follwings:

-Large surface area of mesophyll cells

-Interconnecting air spaces in mesophyll

-Many Stomata

A thick waxy cuticle is NOT an adaptation because the waxy cuticle is not thick, is thin, in order to have a short distance for the carbon dioxide to diffuse into the cells.

The concentration of active vitamins is higher in the 10000 L fermenter.

To compare the amount of active vitamins in a sterilized medium for a 10 L and 10000 L fermenters, both sterilized at 121 C and with a required probability of an unsuccessful fermentation of 0.001, we can calculate the time needed for complete spore inactivation using the formula:

t = (ln (1 - p)) / alpha * exp(Eod / RT)

Where p is the required probability of successful fermentation (0.999), alpha is the pre-Arrhenius constant, Eod is the activation energy for spore inactivation, R is the gas constant, and T is the temperature in Kelvin (394 K for 121 C). We can then use the time to calculate the amount of remaining active vitamin using the formula:

V = V0 * exp(-k * t)

Where V is the remaining concentration of active vitamin, V0 is the initial concentration of vitamin, k is the rate constant for vitamin inactivation, and t is the time.

Using the given values, we can calculate that the time for complete spore inactivation is 18.8 minutes for both the 10 L and 10000 L fermenters. Assuming a rate constant of 0.0014 min⁻¹ for vitamin inactivation, we can calculate that the remaining concentration of active vitamin in the 10 L fermenter is 16.5 mg/L and the remaining concentration in the 10000 L fermenter is 29.9 mg/L.

The movement of water across a plant cell membrane will depend on all of the following factors EXCEPT none of these. The movement of water across a plant cell membrane occurs through the process of osmosis.

Osmosis is defined as the process by which the solvent molecules (in this case, water) move from a region of low solute concentration to an area of high solute concentration via a semipermeable membrane. It's important to note that the movement of water is primarily affected by the concentration of solutes on either side of the plant cell membrane, which is called the solute potential. The movement of water from a region of high water potential to a region of low water potential is known as water potential. The concentration of solutes on either side of the plant cell membrane, the permeability of the membrane to the solutes, and the function of the solute within the cell all play a role in determining the direction of water movement across the plant cell membrane. Therefore, the movement of water across a plant cell membrane will depend on all of the following factors EXCEPT none of these.

Answer:

hello i think it's The resulting proteins made by the human gene are similar to the proteins made by the mouse gene.

Explanation:

I hope this helps

The human gene when placed into the mice functions properly because the resulting proteins made by the human gene are similar to the proteins made by the mouse gene.

The Granulocyte-macrophage stimulating factor or GM-CSF are glycoproteins secreted by immune cells. These are secreted by the GM-CSF gene. These factors function as cytokines in the body

This factor causes the activation of macrophages in small numbers and produces a rapid immune response against a pathogen. GM-CSF also influence mature cells like neutrophils to enhance their migration. Therefore GM-CSF plays a great role in the activation of the immune system against a pathogen and promotes its defence mechanisms.

Thus, even if the human GM-CSF and mouse GM-CSF vary by up to 60 per cent in their DNA sequence, human GM-CSF functions properly in nice because their resulting proteins are similar to each other.

Therefore correct option is B.

The statement is true. The capacity of air to hold water vapor is indeed temperature dependent.

The ability of air to hold water vapor is determined by its temperature. As the temperature increases, the air molecules become more energetic and move faster. This increased molecular motion creates more space between the air molecules, allowing them to accommodate a greater amount of water vapor. In other words, warm air has a higher capacity to hold water vapor compared to cold air.

Conversely, as the temperature decreases, the air molecules slow down, reducing the amount of space available for water vapor. This leads to a decrease in the air's capacity to hold water vapor. When the air reaches its saturation point, where it can no longer hold any more water vapor, it becomes saturated, and any additional moisture condenses into liquid form, resulting in dew, fog, or precipitation.

Understanding the temperature dependence of air's capacity to hold water vapor is crucial in various weather phenomena. For example, when warm and humid air rises and encounters cooler temperatures at higher altitudes, it cools down, causing the water vapor it holds to condense and form clouds. Additionally, the temperature-dependent capacity of air to hold water vapor plays a significant role in the formation of rain, snow, and other forms of precipitation.

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 type of speciation that is driven by character displacement, especially when that characteristic opens up a new food supply and is often referred to as adaptive radiation is called "sympatric speciation".

Sympatric speciation is a process of evolution that leads to the emergence of new species from a single ancestral species, without geographic isolation. This type of speciation occurs when populations of a single species live in the same geographic location but evolve in different ways due to factors such as genetic mutations, chromosomal changes, or differences in ecological niches.

Over time, these differences accumulate and lead to reproductive isolation, creating new species.
