A dialysis tube is filled with water and sugar. It is placed in pure water. What will happen?

Answers

Answer 1

Answer:

The dialysis tubing is semi permeable in nature which means that it allows some molecules to pass through it while hinders the movement of other molecules.

Process:

A dialysis tube filled with water and sugar when placed in pure water will act as a setup that can depict the process of Osmosis. Sugar molecules will not be able to pass the membrane while pure water molecules will move from the area of higher concentration to the area of lower concentration (inside the dialysis tube). This is because the pure water is less concentrated while the water in dialysis tube contains more concentrated solution. This will also increase the liquid level in the dialysis tube.

For example: If we have a  dialysis bag that is not permeable to sugar but is permeable to water and it is  was placed in a beaker full of pure water.

Suppose the bag’s initial weight was 15g but after 15 minutes the bag's weight can change upto 17 grams, why it happened is due to process of osmosis of movement of pure water into the dialysis bag.

The “push” needed to start a chemical reaction is the:

enzymatic energy.

endothermic energy.

activation energy.

reactant energy.

Answers

its reactant energy, hope this helps :)






The “push” needed to start a chemical reaction is the activation energy. Option C is correct.

Activation energy is the minimum amount of energy that is required for a chemical reaction to start. It is the energy barrier that the reactants must overcome in order to form products. Without activation energy, the reactants would not have enough energy to break their bonds and form new ones. This is why chemical reactions do not happen spontaneously.

Enzymes are biological molecules that can help to lower the activation energy of a chemical reaction. This means that enzymes can make reactions happen faster by providing the necessary energy boost. Endothermic energy is the energy that is absorbed by a system during a chemical reaction. Reactant energy is the energy that is possessed by the reactants before a chemical reaction takes place. Option C is correct.

What happens within the cell of a eukaryotic organism when an organelle is no longer functioning properly

Answers

What happens within the cell depends on the organelle that was malfunctioning. For example, if there are no ribosomes in a cell, there are no proteins and hence, no DNA repairs which can lead to problems like cancer. If an organelle is not functioning properly, it could lead to a disease in the body.

Final answer:

When an organelle within a eukaryotic cell fails to function correctly, the cell may utilize autophagy to degrade and recycle the component, or it might trigger apoptosis if the damage is substantial, showcasing the cell's self-maintenance capabilities.

Explanation:

When an organelle within a eukaryotic cell is not functioning properly, the cell can employ several mechanisms to deal with the malfunction. One such mechanism is the autophagy process, where the cell degrades and recycles the damaged organelle. Alternatively, if the damage is too extensive, the cell may undergo programmed cell death, also known as apoptosis, to prevent harm to the organism as a whole. This showcases the cell's ability to maintain internal stability and health, ensuring its optimum functioning within the greater context of an organ or organism.

Autophagy serves as a quality control mechanism, allowing cells to remove malfunctioning organelles and recycle their components, thereby supporting cellular function and health. Similarly, apoptosis plays a crucial role in development and disease prevention by eliminating cells that cannot be repaired. This intricate balance of creating, maintaining, and, when necessary, decomposing cellular components underlines the sophistication of eukaryotic cells.

Green and brown algae share many common features. Both have pigments for trapping sunlight and use photosynthesis for energy. Both store their food as sugars. Both have cell walls and plant-like bodies. However, their DNA suggests that they are not even remotely related to one another. Green algae and brown algae show __________________ evolution, since they look similar, but are not close relatives.

Answers

Answer:- Convergent

Explanation :-

Convergent evolution is the process in which the organisms that are not closely related evolve independently in such a way that they acquire similar traits due to similar environment in which they live or the ecological niche that they occupy. Such structures that result from convergent evolution are called as analogous structures, which perform similar function but have different origins. Convergent evolution can be distinguished from parallel evolution in the fact that in parallel evolution similar traits develop in different species which shared a common ancestor and hence, are closely related.

Thus, since the brown and green algae look similar but are not close relatives they show convergent evolution.

The importance of material transport in plants for photosynthesis

Answers

Raw materials should be transported to the leaves. For transport in plants, they need a transport system to move food, water, and minerals around because for them no heart, no blood, and since these plants do not have a circulatory system, transportation makes up for it.

Material transport in plants, specifically through xylem and phloem tissues, is essential for effective photosynthesis. Xylem transports water and minerals to leaves, while phloem distributes photosynthates throughout the plant.

Importance of Material Transport in Plants for Photosynthesis

The process of photosynthesis is vital for the survival of plants and for the production of oxygen, which is essential for most life on Earth. For photosynthesis to occur effectively, plants must have a system to transport materials such as water, nutrients, and photosynthates (sugars) throughout their tissues. The phloem and xylem are specialized transport tissues found in vascular plants that play critical roles in the movement of these essential materials.

Role of Xylem and Phloem in Material Transport

The xylem primarily carries water and dissolved minerals absorbed from the soil up from the roots to the leaves. This water is crucial for photosynthesis, where it is used to split water molecules to release oxygen and electrons needed in the synthesis of glucose. The phloem, on the other hand, transports the soluble organic compounds made during photosynthesis from the leaves to various parts of the plant through a process called translocation. This ensures that photosynthates reach all parts of the plant for growth, energy, and storage.

Water and nutrient uptake often occurs through structures such as dead velamen, rhizoids, and living rhizodermis in plant roots. Moreover, the process of evapotranspiration and stomatal regulation are crucial in managing water transport and preventing water loss, while maintaining the balance necessary for photosynthesis to proceed efficiently.

What type of organic molecule will be created if alanine bonded with many other amino acids such as serine and glycine

Answers

Ans.

The organic molecules that formed by the amino acids are known as proteins.  Each amino acid binds with other amino acid with the help of peptide bond between amino group of one amino acid and carboxylic group of another amino acid.

Thus, 'when alanine binds with other amino acids, such as with glycine or serine, a protein molecule will formed.'

Final answer:

Alanine bonded with amino acids like serine and glycine forms a polypeptide. This molecule is linked by peptide bonds through a dehydration synthesis reaction, and its sequence determines its structure and function.

Explanation:

When alanine is bonded with many other amino acids, such as serine and glycine, the organic molecule created is a polypeptide. A polypeptide is a long chain of amino acid residues linked together by peptide bonds. Each amino acid is attached to the next by a dehydration synthesis reaction, releasing a molecule of water and forming the peptide bond. The sequence in which these amino acids are linked determines the primary structure of the polypeptide. For example, the sequence Gly-Trp-Ala is distinct from Ala-Trp-Gly because the location of the free amine and carboxyl groups would be different. The polypeptide can fold into complex shapes to form proteins which have variable functions, depending on their amino acid sequence and resultant three-dimensional structure.

Which survivorship strategy is used by the type II species?

Answers

Answer:

Type II species include mice, birds and other similar organisms that have constant survivor ship rates as well as mortality rates during the whole period of their expected life/

If we look at survival ship curve of type II species as depicted in attached figure, we can see that it shows a constant slope and contains a straight line. The slope is in such a way that with the passage of time it decreases till reach zero.

The survival ship strategy used by type II species is this that they lie somewhere between  semelparous ( comprised by single reproductive episode before death) and iteroparous (comprised by multiple reproductive cycles throughout the lifetime).

They have a probability of dying at constant level therefore they adopt a strategy in between of having more than one and less than multiple reproductive cycle throughout their life. In this way, they maximize their survival span.

What is the difference between a population showing exponential growth and a population showing logistic growth? (Site 1)

Answers

Population growth refers to the patterns governing how the number of individuals in a given population changes over time. These are determined by two basic factors: the birth rate and death rate.

Answer:

A population can show two types of growth, exponential or logistic. Exponential growth occurs in case of unlimited resources like unlimited food or space. Organisms in the population do not have to compete with each other and the population can grow indefinitely. Such a growth model shows J shaped curve when population size is measured against time.

Logistic growth occurs in case of limited resources and competition. The population has carrying capacity i.e. maximum number of individuals it can hold before the population growth becomes stagnant. This model shows S shaped curve when population size is measured against time.

In real life logistic growth is shown by populations. Exponential growth is not possible since the resources get used up after some time.

Answers

Answer : incomplete dominance

Explanation:

For a given trait, there are basically two types of alleles that are present. One allele is the dominant one and the other is recessive. Generally , the phenotype of an individual corresponds to the one coded by the dominant allele when both the alleles are present for a given trait, that is if a heterozygous condition is there. However, in some cases the dominant allele is not completely dominant over the recessive allele.When the dominant allele is not completely dominant then under heterozygous condition the phenotype expressed is a blend of the phenotypes expressed by both the alleles. For e.g if a red flower is crossed with white flower and we get a pink flower we can say that the allele shows partial dominance over the other. Similarly in the given question, the dominant allele is partially dominant over the recessive allele thus, a blended phenotype appears in the progeny. Such type of inheritance is known as incomplete dominance, partial dominance or semi dominance.
