For some parents, their offspring have larger beak depths; for others it's smaller. How does the concept of variation of traits help to explain this?

Answers

Answer:

beak depth is a complex (quantitative) trait

Explanation:

Additive effects refer to the resulting effects of two or more genes acting together. Beak depth is a quantitative trait whose variation is determined by the additive effects of many genes acting together and the environment. In quantitative traits, variation is continuous and produces a range of phenotypes. In consequence, in this case, some offspring will have a larger average beak depth compared to their parents, whereas others will have a smaller average beak depth compared to their parents. It is due to the combination of alleles or 'additive effects' inherited from different parents, and the interaction between these genes and the environment. Heritability refers to the proportion of quantitative trait variation due to additive genetic factors: a higher heritability is due to the predominance of additive genetic effects and less influenced by environmental effects.

Nitrogen fixation converts nitrogen gas to usable nitrogen for plants?

True
False

Answers

Answer:

True, nitrogen fixation converts atmospheric nitrogen into nitrogen that can be used by plants.

Explanation:

Think about water. There's plenty of water on Earth, but very few is actually drinkable, at least for humans. So we have to fix it by filtering out dangerous bacteria in the water and other dangerous stuff before being able to actually drink it. Same with atmospheric nitrogen. It must be "fixed" before plants can actually use them.

How do temperature and concentration of monounsaturated phospholipids change the rate at which molecules permeate the plasma membrane?

Answers

Answer: At low temperatures the fluidity of the membrane decreases and it favors fluidity. The higher the concentration of unsaturated fatty acids, the less tightly the phospholipids can bind and the more fluid (more permeable).

Explanation:

The plasma membrane is a lipid layer that delimits the entire cell, dividing the extracellular medium from the intracellular (the cytoplasm of a cell). They are composed of phospholipids, which are molecules composed of glycerol, a phosphate group and two lipid chains (such as fatty acids). Glycerol is a three-carbon molecule that functions as the backbone of this membrane. A geometry is formed that allows the phospholipids to line up side by side to form broad sheets. They are insoluble in water, but their unique geometry causes them to aggregate in layers without any energy input, as they possess a hydrophilic phosphate head and a hydrophobic tail consisting of the two fatty acid chains. The hydrophilic heads of the phospholipids in a bilayer membrane face outward and are in contact with the aqueous fluid inside and outside the cell. Because water is a polar molecule, it readily forms electrostatic (charge-based) interactions with the phospholipid heads.

Selective permeability is a property of the plasma membrane and other semipermeable membranes that allow only certain particles to pass through them. In this way, those particles that are needed by the cell can enter the cell and those that are not useful to the cell are prevented from entering. In the same way, the cell can eliminate the particles it has produced as waste. In this way, the entry and exit of substances through the membrane is regulated and the correct functioning of the cell is achieved.

For a particle to be able to cross the plasma membrane it must have a size equal to or smaller than the pores of the membrane, it must have the opposite charge to the charge of the membrane or simply have a neutral charge, and if it is larger than the pores it must be dissolved in a solution, decreasing its size and thus be able to enter the cell through the membrane.  

Plasma membranes are fluid and this fluidity depends on their lipid composition and temperature. Depending on the temperature, membrane lipids can be found in two different states or phases: gel (solid-like, with more rigid hydrocarbon chains) and liquid crystal (more fluid, with more mobile hydrocarbon chains). At low temperatures the fluidity of the membrane decreases and in these conditions the increase of its concentration favors fluidity. The temperature at which the transition from one state to the other occurs is the phase transition temperature (Tc). At values below Tc, the bilayer is in the gel state and at higher values it passes to the liquid crystal. It should be noted that there is an equilibrium between the gel state and the liquid crystal state and that the characteristics of the lipids of the bilayer condition the transition temperature. In the case of bilayers consisting of only one type of lipid, the Tc is well defined. But biological membranes are complex lipid mixtures and the transition from one state to another occurs over a range of temperatures. The presence of short-chain or unsaturated fatty acids reduces the transition temperature, while saturated fatty acids and the increase in the length of the hydrocarbon chains cause this temperature to rise. Then, phospholipids with unsaturated fatty acid tails cannot bind as tightly due to the bent structure of their tails. For this reason, a membrane of unsaturated phospholipids remains fluid at lower temperatures than a membrane of saturated phospholipids.  

The fluidity of a membrane is the ability of a molecule to move through it. In short, the higher the concentration of unsaturated fatty acids, the less tightly the phospholipids can bind and the more fluid (more permeable) the membrane will be even at low temperatures. However, at low temperatures the fluidity of the membrane decreases (lower permeability) but the effect will depend on the composition of the fatty acids. To determine the exact permeability, it is necessary to relate the concentration of unsaturated bonds and the length of the fatty acids in the phospholipids and the temperature.

What type of organisms make up the majority of life on the surface of the pelagic zone?
Answer:
plankton and algae

Hope that help

The types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae. That is the last option, as plankton and algae are the primary producers in the surface layer of the pelagic zone.

What are the zones of water?

The pelagic zone is the open ocean area that comprises the largest ecosystem on Earth. It is divided into different layers depending on the depth and amount of sunlight that penetrates the water. The surface layer of the pelagic zone, also known as the photic zone, is the layer that receives enough sunlight for photosynthesis to occur, and it is where most of the ocean's primary production takes place.

Hence, the types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae, which is the last option.

oil-rich countries in the middle east cover about 4% of earth's total land area but posses about 48% of the world's known oil reserves. what is the main reason for high concentration of reserves in this part of the world?

Answers

The correct answer is A. Geological processes.

Explanation

Oil is a hydrocarbon of fossil origin by geological processes that transforms large amounts of organic matter deposited on anoxic bottoms of seas or lake areas of the geological past, which were later covered by heavy layers of sediment. This causes organic materials to be transformed into oil by the heat and pressure of the upper layers. However, this phenomenon does not occur in all parts of the earth because in some, as in the case of the Middle East, there were large amounts of organic matter that became an oil reserve. So the correct answer is A.
