Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These characteristics are passed on to their offspring.
According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.
Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

What effect would uncontrolled population growth have on land?*
A) increased soil fertility and decreased erosion
B) increased soil fertility and increased erosion
C) decreased soil fertility and decreased erosion
D) decreased soil fertility and increased erosion
(D) is the right answer ........
Uncontrolled population growth affect the soil fertility and soil erosion i.e. it decreases soil fertility and increases soil erosion.
what is uncontrolled population growth?uncontrolled population growth is the area where the proportion of urban population has increased faster than the nation's average rate of population growth.
what is soil erosion ?soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.
what is soil fertility ?soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth.
The population increases so that the demand for food increases, lack of arable land leads to intensive cultivation, reclamation to expand cultivation land on sloping hills increases soil erosion, causes degradation, infertile soil.
Therefore, use of chemical fertilizers and plant protection chemicals makes land resources, surface water sources of the mainland contaminated.
Reclamation makes area of forestland narrowed, depletion of natural resources, natural environment polluted.

Certain environmental changes such as changes in amount of available carbon dioxide as well as amount of sunlight can affect a plant's photosynthetic processes.
There are several environmental changes that affect the rate of photosynthesis. Photosynthesis is the process by which plants produce their own food in the presence of sunlight by the combination of water and carbon dioxide to yield glucose.
There are two main environmental changes that could affect the rate of photosynthesis and these are;
Changes in amount of sunlightChanges in amount of available carbon dioxideThese changes are capable of increasing or decreasing the rate of photosynthesis.

The nucleotide sequence TCG CCG TAT AAC exhibits an insertion mutation without a frameshift (Option A).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.An insertion mutation is a type of mutation where one or more nucleotide bases are added to the original sequence.A frameshift mutation is a type of mutation that alters the open reading frame of the nucleotide sequence, thereby modifying the linear order of amino acids that will be added from the new nucleotide sequence.An insertion mutation of three consecutive nucleotides does not modify the open reading frame of the sequence because they encode for a new codon.In conclusion, the nucleotide sequence TCG CCG TAT AAC exhibits an insertion mutation without a frameshift (Option A).

OC.
Wastes will build up in cells and will eventually be excreted from

The statement 'wastes will build up in vital organs, and the organism will experience disease' describes the overall consequence of proteins containing mutations. Defective proteins contain mutations.
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.
A non-silent mutation can produce a change in the amino acids encoded by the nucleotide gene sequence, thereby modifying the tridimensional (3D) structure of the resulting protein.
In consequence, mutated proteins may be defective and accumulate as waste in a given organ/cell where they are expressed to perform specific functions.

What is the difference between diffusion and osmosis?
What makes a membrane semipermeable?
What characteristics of a molecule affect whether it can pass through the plasma membrane of a cell?
In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
In the simulation, when protein molecules were more highly concentrated on the inside of the cell than outside of the cell, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
Why is it important that the plasma membrane surrounding cells is semipermeable?
What would happen if it were not semipermeable?
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and from movement of water molecules along the concentration gradient.

Your answers may vary, but these sample answers are a model to follow.
Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
A semipermeable membrane allows some substances to pass through it.
The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
What is the difference between diffusion and osmosis?Diffusion is the movement of particles from an area of higher concentration to one of lower concentration while on the other hand, osmosis is the movement of particles from a semipermeable membrane.
Cell membrane is selectively permeable which only allows some molecules inside the cell because of its structure. So we can conclude that diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
When protein molecules were evenly distributed on both sides of the membrane, the solution will be isotonic because of the same quantity on both sided. There is no movement of water in the body.
When protein molecules were more highly concentrated on the inside of the cell than outside of the cell, the solution will be hypotonic because of the less amount of water in the body.
