Explanation:
In an experiment to investigate a factor affecting photosynthesis, a leaf of a potted plant which had been kept in the dark overnight was covered with aluminum foil as shown in the diagram below 1. Aluminium foil The set up was kept in sunlight for three hours after which a food test was carried out on the leaf. (a) Which factor was being investigated in the experiment? b) What food test was carried out? (i) State the results of the food test (ii) Account for the results in c (i) above
Answers
Answer:
Photosynthetic activity.
Explanation:
The photosynthetic activity of the plant was being investigated in the experiment and no photosynthesis will occur because the aluminium foil reflect 95% of sunlight. Starch test is the food test that was carried out in the experiment. Starch from plants is broken down into its constituent sugar molecules by the plant body in order to provide energy to the tissues so if there is no photosynthesis occurs, the plant body uses starch so decrease occur in the concentration of the starch molecules when the starch food test will occur.
Explain how 2 polynucleotides can twist helically around each other to form a double helix of DNA?
Answers
Explanation:
The antiparallel arrangement of the two strands is what causes the twist. Because the strands run in opposite directions, they pull the sides of the molecule in opposite directions, causing the whole thing to twist around itself.

A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answers
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.
Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all three types of solutions (hypertonic, hypotonic, and isotonic).
Answers
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.More about osmosis here: https://brainly.in/question/1213189

Harry is doing a research project on the movement of plants from the ocean to land. He leaned that plants evolved
vascular tissues, which enabled them to pull water from the ground and survive on land. Which is most likely
another adaptation that contributed to the success of land plants?
cell walls?
chloroplasts
waxy cuticle
gametes
Answers
Answer:
Waxy Cuticle
Explanation:
Waxy Cuticle retains water. It's the closest in terms of surviving on land. For instance, the plants living in water do not need waxy Cuticle to retain or maintain water. The plants on land requires waxy Cuticle because the temperature is hotter than in the water and they are at higher risk of loosing water during hot seasons and climate. waxy Cuticle aids in their water retention allowing them to adapt to live on land.

A. what is the name of two different types of scales found on maps?
B. how does each scale work?
Answers
Answer:
Bar and lexical.
Explanation:
Bar and lexical are the name of two different types of scales that are found on maps. Bar scales are used more frequently in the maps because they represent or show the distance ratio visually instead of in words, while on the other hand, lexical scales may be expressed in words, as a ratio, or as a fraction. Examples are 1:10,000 or 1/10,000. Using map scales is very important in the real world if you want to find out the distance you are traveling.

Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then, the remaining liquid is heated to remove the water, leaving a residue of substance B. Which statement about substance A and substance B could be correct?
Substance A is rice, and substance B is sugar.
Substance A is rice, and substance B is sugar.
Substance A is sugar, and substance B is instant coffee.
Substance A is sugar, and substance B is instant coffee.
Substance A is sand, and substance B is alcohol.
Substance A is sand, and substance B is alcohol.
Substance A is alcohol, and substance B is salt.
Answers
The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Which of the following is not true of integrin? Question 4 options: Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix. Integrins undergo extensive conformational changes on binding to molecules on either side of the plasma membrane. Certain intracellular chemical signals can activate integrins from inside the cell, causing them to reach out and grab hold of extracellular structures. When integrin binds to the extracellular matrix, it stretches into an extended, activated state to attach to molecules on the inside of the cell.
Answers
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
The statement i.e. not true is Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.

Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.
Explanation:
The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.
