Answers:
- Mendelian inheritance states that traits are determined when offspring receive <u>alleles </u>for each trait from <u>Parents</u>.
Explanation:
As per Mendel, all the traits which are present in an offspring are determined by specific genes which exist in alternate forms called alleles. For example: The height of a plant is a trait which is determined by alleles T for tall height and t for small height of same gene. The organisms acquire these alleles from parents (one allele from each parent).
--------------------------------------------------------------------------------
- Traits can be <u>Dominant </u>which means they can be seen and are capable of masking a different trait.
Explanation:
Dominant trait means when only a single dominant allele for the trait in an organism is enough for the organism to depict the trait. For example: In pea plant, purple flower color is a dominant trait over white. So any plant who contains only one dominant allele for purple (allele P) will have purple flowers but all plants that have two pp alleles will have recessive trait i.e White flowers.
-------------------------------------------------------------------------------------
- Traits can also be <u>Recessive </u>which means they can be masked.
As mentioned in above example, white flower color of pea plant is a recessive trait. Recessive means that if a plant has one copy of recessive and one copy of dominant allele, the dominant allele will suppress or mask the effect of dominant allele. Example is the above case of flower color when a plant with genotype Pp will have purple but not white flowers.
-------------------------------------------------------------------------------------------
- Alleles are different versions of the same <u>gene </u>in an organism.
Alleles are just alternate forms of a gene. For example if a plant height is determined by a gene L, it has two forms capital L and small l which are alleles of same gene. But capital L is for tall height and small l is for short height.

Cells differentiate in order to create cells that perform specific functions.
The plants would ultimately die.
Although the plants won't need oxygen to make photosynthesis occur, it would be unable to perform cellular respiration. They will be unable to respire and produce the product of cellular respiration which is CO2 + H2O + Energy. These are necessary reactants for photosynthesis. Eventually, photosynthesis will consume more CO2 than it produces with cellular respiration. They won't have a sufficient food source and eventually die off.
Answer:
The microscope is an instrument used for the visualization of the cell and its other component. Different types of microscope are compound microscope, electron microscope and binocular microscope.
The adjustment of the slide is important to visualize the focused object. A proper source of light is required to focus the image. At high magnification, the fine focus control is used for the adjustment. At 100 X the oil is used to visualize the object.
Are the pythons a new species?
How can the python population be controlled?
How quickly are pythons reproducing in the Everglades?
<span>How are the pythons affecting other animal populations?
Among the choices, the question least likely to be asked is ARE THE PYTHONS A NEW SPECIES?
It may be asked but the other three questions are more important. This is because we need to know the effect of the growing python population has on the existence of other animals in the Florida Everglades.
Pythons are hunters. Uncontrolled population growth will result to the decrease of the population of other animals because they are the prey of the pythons. Therefore, rate of reproduction and observation regarding their immediate effect to their environment are of utmost importance compared to whether pythons are new species or not.
