Answer:
Likewise, logistic growth (that's what the problem is called, the logistic curve is the variable that moves between the Y and X axes) is a refinement of exponential growth.
Explanation:
The exponential function is a valid model for continuous growths or decreases in which the conditions are always equally favorable: increase of the capital entered into a bank, disintegration of radioactive substances ... The populations of living beings begin to grow according to an exponential curve but if there are no catastrophes, they invade their vital space and, due to the limitation of food, etc., their growth is cushioned, not exceeding their limit population. This type of increase, dampened by a saturation level is called logistic growth.
Answer: The correct option is C.
myrmecophytes.
Explanation:
This is because ants and myrmecophytes have mutualistic relationship in which the plants provide food, and accomodation to the ants through the structural adaptations of plants like dormatia, fruiting bodies, nectaries flowers. The ants inturn ahelp the myrmecophyte in pollination, seed dispersal, to defend it against Intruders and also help it to gather nutrients.
The correct answer is: B) The F1 variance is due only to environmental factors.
According to Mendelian genetics: he crossed two purebred parents with differing traits to be sure that there were no other factors contributing to the outcome of the cross. When two purebred parents are crossed, all of the offspring should be genetically the same (heterozygous).
In the example above, we can see that there is phenotypic variance among the offspring, so we can conclude that it must be due only to environmental factors.
Answer:
D
Explanation:
Osmosis is a biological phenomenon whereby the molecules of a solvent moves through a selective permeable membrane from an area of low solute concentration to an area of high solute concentration.
There are three types of osmotic solutions viz;
Isotonic; which has an equal solute concentration
Hypotonic; which has a lower solute concentration
Hypertonic; which has a higher solute concentration
When a living cell is placed in a solution, the solvent molecule (which is usually water) moves in or out of the cell depending on whether the cell has a higher solute concentration (hypertonic) or lower solute concentration (hypotonic) in comparison with the solution it was immersed in.
A good example can be observed in the absorption of water by the root hairs of plants; root hairs, due to the accumulation of minerals, possess a lesser concentration of water molecules than the soil i.e the root hairs are hypertonic. Due to this osmotic gradient, water (solvent) moves from the SOIL, which has a lower concentration of solute, to the ROOT, which has a higher concentration of solute.
It is an example of a theory because, despite the way it is commonly used, a theory is an idea that has been proven over and over again, and there is proof that all life is made of cells.
