Answer:

Enzymes are proteins that catalyse (speed up) vital chemical reactions inside the body. Enzymes will only function properly under a small range of certain conditions, such as preferred pH and temperature. If any conditions are outside their specific range then the enzymes cannot function. This could cause the organism to die. Homeostasis relies on automatic control systems that include nervous responses (nervous system) or chemical responses (endocrine system). Receptors and effectors are also needed

Explanation:

Paramecia that live in freshwater have contractile vacuoles, while those that live in saltwater do not, because osmosis operates differently in the two solutions.The water potential of the surrounding environment affects the cells of paramecia, which in turn determines whether they have contractile vacuoles or not.

Paramecia are eukaryotic unicellular organisms that are often found in freshwater. They possess contractile vacuoles that aid in the regulation of water content within the cell. These organelles, which are absent in the paramecia that live in saltwater, remove excess water from the cytoplasm by collecting it in a central vacuole. When the vacuole is full, it contracts and expels the water out of the cell through an opening known as the cytoproct. Freshwater is hypotonic to paramecia, which means that the concentration of solutes inside the cell is higher than the concentration of solutes outside the cell. This causes water to move into the cell, which could lead to it bursting if not for the contractile vacuoles. In contrast, saltwater is hypertonic, which means that the concentration of solutes outside the cell is higher than the concentration of solutes inside the cell.

As a result, water moves out of the cell, and the contractile vacuoles are not necessary. The paramecia in saltwater do not need to worry about osmotic lysis, making the contractile vacuole unnecessary.

In conclusion, paramecia that live in freshwater (hypotonic solution) have contractile vacuoles, while those that live in saltwater (hypertonic solutions) do not, because osmosis operates differently in the two solutions.

Answer:

1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.

In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.

2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.

3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.

Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.

4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.

The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.

Answer:

Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant's root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.

The ratio of these two types of DNA molecules would depend on the timing of the transfer to the 15N medium and the length of the bacterial generation time.

In the Meselson and Stahl experiment, they grew E. coli bacteria in a medium containing heavy nitrogen isotope 15N for several generations, allowing the bacteria to incorporate 15N into their DNA. They then transferred the bacteria to a medium containing light nitrogen isotope 14N and let them divide for two generations.

If researchers started their bacterial cultures in 14N instead of 15N and then flooded the media having 15N instead of 14N, we expect the ratios of DNA molecules after two generations in medium containing 15N:

After the first generation, all of the DNA in the bacteria would have a hybrid density, since each DNA molecule would have one strand that was synthesized using 14N and one strand that was synthesized using 15N.

After the second generation, we would expect to see two types of DNA molecules: those that had fully incorporated 15N and those that still had one 14N strand and one 15N strand.

If the transfer occurred early in the first generation and the generation time was short, we would expect to see mostly hybrid DNA molecules and only a small amount of fully 15N-labeled DNA. If the transfer occurred later in the first generation and/or the generation time was longer, we would expect to see a higher proportion of fully 15N-labeled DNA.

The correct option is C; Through the opening and closing of stomata , located on the leaves' surfaces, are involved in regulating gas interchange and water release. Plants regulate water by opening and closing stomata.

Stomata are small pores placed in the leafs' surfaces, whose opening is regulated by two guard cells surrounding them.

These pores are involved in gas interchange -letting CO₂ get into the plant, and O₂ leave it- and the transpiration process -expelling water through transpiration-.

Guard cells can expand or contract according to the plants' needs, causing the stomata to open or close.

Stomata opening and closure depend on water and CO₂ concentration inside the plant.

·        If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.

·        If CO₂ levels are too low, stomata open to gain it.

So, stomata affect photosynthesis by controlling gas interchange -CO₂ and O₂- and water release -transpiration-.

Water balance:

·        Stomata also regulate water vapor flow through transpiration.

·        By limiting its exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.

According to this information, plants regulate water in their bodies by opening and closing stomata.

If water had weak surface tension, insects would not be able to land on or walk on water.

Surface tension is the force acting on the surface of water that makes it to behave like a stretched elastic skin.

Surface tension owes to the intermolecular attraction between water molecules. The molecules at the surface of water are drawn inwards by other molecules causing the molecules at the surface to contract. This surface tension enables insects to land on or walk on water.

So, without surface tension of water, insects would not be able to land on or walk on water.

Given that Stem Bromelain has an enzymatic activity of 0.542 U/mg, and there are 20 billion bacteria in our teeth. We need to calculate how long it takes to degrade all of the biofilm created by the bacteria.Assumptions and explanations used in the calculation: Assumption: The mass of the biofilm is not given. Therefore, it is assumed that the biofilm's mass is 1 mg, as the enzymatic activity of bromelain is provided per mg. If the biofilm's mass is different, the result will be different.

We know the enzymatic activity of bromelain, which is 0.542 U/mg.We are given that the number of bacteria in our teeth is 20 billion. The biofilm is created by these bacteria. Bromelain is supposed to degrade the biofilm. Therefore, we need to calculate the mass of the biofilm. The mass of the biofilm is assumed to be 1 mg, as the enzymatic activity of bromelain is given per mg.Now we can use the given data to calculate the time required for bromelain to degrade all of the biofilms created by the bacteria.First, we need to find the total enzymatic activity required to degrade the biofilm. The mass of the biofilm is assumed to be 1 mg.Enzymatic activity of bromelain = 0.542 U/mgTotal enzymatic activity required to degrade 1 mg biofilm= 0.542 U/mg × 1 mg= 0.542 UThe total enzymatic activity required to degrade the biofilm created by the 20 billion bacteria is:Total enzymatic activity required= Enzymatic activity per bacteria × Total number of bacteria= 0.542 U/mg × 20 billion= 1.084 × 10^10 UTo find out how long it takes for bromelain to degrade all of the biofilm, we need to know the rate of degradation. The rate of degradation depends on various factors, such as temperature, pH, etc., which are not provided in the question. Therefore, it is impossible to calculate the time required for bromelain to degrade all of the biofilms created by the bacteria without knowing the rate of degradation.
