The cell membrane is selectively permeable because substances do not pass through it indiscriminately. This means that only selective molecules pass through it. So the correct answer choice is option (B).

Selective permeability of a cell membrane refers to its ability to distinguish between different types of molecules, allowing only some molecules through while blocking others. A cell membrane is called selectively permeable because it allows only specific molecules to pass through. Only specific molecules, such as water and gas molecules, can pass directly through the cell membrane. It stops the flow of other molecules towards the two sides. Many large molecules like glucose and other sugars cannot do this. Water can pass between lipids. The most common example is the phospholipid bilayer cell membrane that surrounds every cell in our body.

Since plants and photosynthetic protists do not have the machinery for being heterotroph but they can make their own food in the presence of chloroplast, this is the reason why they possess chloroplast. Animals cells on the other hand cannot perform photosynthesis and hence do not possess chloroplast.

Heterotroph is one of the types of mode of nutrition. In this the organism obtains their food from some other organism that can either be plant or another animal. The example of heterotrophs are all the animals and humans.

Photosynthesis is the process of synthesizing food by capturing the sunlight energy and releasing oxygen as the by-product.

An ANN is built from a network of linked units or nodes known as artificial neurons, which are roughly modelled after the neurons in the human brain. Each link, like synapses in a human brain, can send a signal to the other neurons. An artificial neuron receives signals, analyses them, and can signal neurons to which it is linked. Each neuron's output is generated by certain non-linear function of the total of its inputs, and the "signal" at a link is a real number. The connections are referred to as edges. Neurons and edges usually have a weight that changes as learning progresses.

In the presence of the sodium-glucose cotransporter, it is expected that: the internal glucose concentration will also increase.

In the experiment conducted by the researchers, artificial membrane vesicles were created in a laboratory and placed in a series of aqueous solutions to test primary and secondary active transport systems. In particular, they tested an H+/glucose symporter in a variety of conditions and in the presence and absence of an H+ pump.

When the H+/glucose symporter is present, it is expected that glucose concentrations will increase. This is due to the action of the symporter, which utilizes the H+ gradient across the membrane vesicles to transport glucose molecules from an area of low concentration to an area of high concentration.

In the presence of the H+ pump, the H+ gradient is increased, which further enhances the ability of the symporter to transport glucose molecules. As a result, the internal glucose concentration will increase.

In addition to the H+/glucose symporter, secondary active transport systems can also result in increased glucose concentrations. These systems involve the coupling of an energy source, such as ATP, to the transport of molecules across the membrane.

One example of a secondary active transport system is the sodium-glucose cotransporter, which uses the energy from sodium ions to transport glucose molecules. Therefore, in the presence of the sodium-glucose cotransporter, it is expected that the internal glucose concentration will also increase.

The melting temperature (Tm) of a primer is the temperature at which half of the primer molecules are bound to the DNA template and half are unbound. If the Tm of a primer is too low, it will not bind effectively to the region of DNA that we want to amplify because it will anneal to non-specific regions of the template DNA, leading to non-specific amplification.

Similarly, if the Tm of a primer is too high, it may not bind effectively to the template DNA at all, leading to low amplification efficiency. Therefore, it is important to choose primers with Tm values that are appropriate for the target DNA sequence to ensure efficient and specific amplification.

It's possible that the two primers may not bind effectively to the desired DNA region for amplification due to several reasons. These could include mismatched base pairs, secondary structures like hairpins or dimers, or an unsuitable annealing temperature. Ensuring optimal primer design and selecting the appropriate annealing temperature can help improve primer binding and successful DNA amplification.

Production of gametes from diploid cells exists the correct answer. This is not one of the functions of mitosis.

Multicellular creatures depend on mitosis to produce new cells for growth and to replace damaged or worn-out cells, such as skin cells. Asexual reproduction in many single-celled organisms is mostly accomplished through the process of mitosis.

When a cell splits into two, mitosis, a type of cell division, ensures that each new daughter cell has the same genomic makeup.

During mitosis, two cells known as daughter cells are produced. The number of chromosomes must remain constant, and any newly formed daughter cells must have genetic material that is similar to that of the parent cell.

After cell division, it aids in keeping the same number of chromosomes in the daughter cells. It is in charge of the expansion and maturation of multicellular organisms. It aids in the healing of broken tissues. It aids in maintaining the right size of the cell.

1.The per-worker production function in the Basic Solow Growth Model can be written as: Y = K * α * L * (1 - α)

where Y is output per worker, K is capital per worker, L is labor, and α is the elasticity of output with respect to capital. 2.The equation of motion for this model is: dY/dt = s(Y-c) - (δ+1)K. where s is the savings rate, c is consumption per worker, δ is the depreciation rate, and t is time.

3.The steady-state capital per worker (k∗) is given by:

k∗ = δ + 1

4.The steady-state level of output per worker (y∗) is given by:

y∗ = αk∗L

where α is the elasticity of output with respect to capital.

5.The steady-state level of consumption per worker (c∗) is given by:

c∗ = s(y∗-L)

6.A well-labeled figure showing steady state capital per worker, steady state output per worker, and steady-state consumption per worker would include the following:
