Answer:
It was concluded that the dialysis tubing doesn't allow all kinds of substances to pass readily through the pores of its membrane. This means that it is selective in its permeability to substances. The dialysis tubing was permeable to glucose and iodine but not to starch.
Explanation:
The dialysis tubing is selectively permeable because substances together with water, glucose, and iodine were able to pass through the tubing but the starch molecule becomes too big to skip. 3. Sucrose is a disaccharide and therefore much large than the glucose, a monosaccharide, that becomes used within the experiment.
How could you tell the dialysis tubing turned permeable to the iodine?This could be regarded from the color alternate within the answers within the beaker and the bag. The tubing became permeable to iodine and so the content of the bag became blue-black in color indicating the presence of starch. Glucose is also readily handed through the pores of the membrane.
Which materials crossed the dialysis membrane?The dialysis membrane is one of the essential components that determine dialysis overall performance. these membranes permit only low-molecular-weight molecules, consisting of sodium, potassium, urea, and creatinine, to skip through even as blocking proteins, along with albumin, and different large molecules.

The Texel sheep is a breed of sheep that has gone through selective breeding for both food and wool production. The wool is of medium thickness without black fibers and commonly used in crafts. The sheep are bred for their large muscle size. The increase in muscle size has led to increased size in offspring.
How has this biotechnology harmed the Texel sheep?
Answer:
loss of genetic diversity
Explanation:
Artificial selection, also known as selective breeding, refers to the identification by humans of desirable phenotypic features (traits) in plants and animals and the subsequent breeding procedures to enhance and perpetuate these traits in offspring. As a consequence of artificial selection, future generations of selectively bred animals/plants will share favorable gene variants (alleles), thereby genetic diversity will decrease in the population. This reduction in the gene pool will affect genetic progress and consequently also breeding programs in the future.

write short notes on the following. (a) Cytoplasm (b) Nucleus of a cell
Answer:
Explanation:
Cytoplasm Structure Cell organelles are various structures existing inside cells. All these structures are distinct and perform specific functions. Cells have three main elements i.e., plasma membrane, and cytoplasm and the nucleus. The plasma membrane or cell membrane is a bi-lipid membranous layer, parting the cell organelles from its outside environment and from the different cells. It is the external covering of a cell where all different parts, including cytoplasm and nucleus, are enclosed. Next, is the nucleus, one of the biggest organelle. They have exclusive control of a cell. Lastly, the cytoplasm is a jelly-like material in which the cell organelles are implanted. The cytoplasm is an essential component of the cell. It is a semi-liquid jelly-like material, which joins the nucleus and the cell membrane. In the cell, the cytoplasm is embedded, while other cell organelles such as endoplasmic reticulum, mitochondria, ribosomes, vacuoles, etc. are all suspended within it. It can easily be examined under a microscope through the staining technique. Functionally, it is the site for several chemical reactions within a cell. Most of the cellular metabolism takes place here. Cytoplasm Function One of the major functions of cytoplasm is to enable cells to maintain their turgidity, which enables the cells to hold their shape. Other functions of cytoplasm are as follows: The jelly-like fluid of the cytoplasm is composed of salt and water and is present within the membrane of the cells and embeds all of the parts of the cells and organelles. The cytoplasm is home to many activities of the cell as it contains molecules, enzymes that are crucial in the break down of the waste. The cytoplasm also assists in metabolic activities. Cytoplasm provides shape to the cell. It fills up the cells thus enabling the organelles to remain in their position. The cells, without cytoplasm, would deflate and substances will not permeate easily from one to the other organelle. A part of the cytoplasm, the cytosol has no organelles. Rather, the cytosol is enclosed by matrix boundaries that fill up the cell section which does not hold the organelles. The whole cellular content of a living cell is called protoplasm. The cytoplasm, nucleus and all other living components of the cell together make up the protoplasm of a cell.NucleusThe nucleus is an important element of the cells. It is a membrane-bound organelle that is typically found in the eukaryotic cells. Eukaryotes usually have a single nucleus, whereas some cell types do not possess a nucleus (RBC-Red Blood Cells).

the Krebs cycle occur(s), breaking down pyruvic acid into carbon dioxide in a series of reactions.
Explanation:
The innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.
What is the Krebs cycle?The primary source of energy for cells and an essential component of aerobic respiration is the tricarboxylic acid (TCA) cycle, sometimes referred to as the Krebs or citric acid cycle. The cycle converts the acetyl coenzyme A (acetyl CoA) chemical energy into the reducing force of nicotinamide adenine dinucleotide (NADH).
The TCA cycle is a component of the broader glucose metabolism, which involves the oxidation of glucose to produce pyruvate, which is then further oxidized and reaches the TCA cycle as acetyl-CoA.
The cycle's half of intermediates also serves as the starting point for pathways that lead to significant molecules such as fatty acids, amino acids, or porphyrins. The integrity of the cycle is compromised and the cycle ceases to operate when any of these intermediates are so diverted. Only if the deflected intermediate or a succeeding intermediate that contributes to oxaloacetate can be replaced by anaplerotic (refilling) processes can vital energy production be restarted.
Therefore, the innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.

Many natural ecosystems have been destroyed by human activity. To better manage our remaining natural ecosystems, we must first understand how the ecosystems are structured. One way to do this is to determine how the organisms in the ecosystem obtain the matter and energy they need to survive. The figure below shows a simplified food web. Use the figure to answer the following questions.
Which of the following correctly shows one pathway for the flow of energy to an owl?
A.
owls → squirrels → foxes
B.
green plants → mice → squirrels
C.
owls → green plants → mice
D.
green plants → squirrels → owls
The correct pathway for the flow of energy to an owl is from green plants to squirrels, and from squirrels to owls. Therefore, the correct statement is option D.
What is the flow of energy in the food web?This pathway starts with green plants, which are producers and can prepare their own food. The energy from the plants then flows to squirrels, which are herbivores and eat the plants. Then, the energy is transferred to owls, which are carnivores and eat the squirrels.
This pathway represents the flow of energy through multiple trophic levels in the food web, starting with producers and ending with a tertiary consumer.
However, the flow of energy in an ecosystem is important for preserving natural ecosystems. The energy that flows through ecosystems originates from the sun and is captured by producers such as green plants which then move towards food chain as organisms consume other organisms.
Therefore, the correct pathway for the flow of energy to an owl is from green plants to squirrels, and from squirrels to owls.
