Grasses and Grains are pollinated by the wind. and a plant is a pollinated seed that grows. there is a difference. most grasses are pollinated by the wind once again monocotyledonous flowering plants. flowers are pollinated by bees flying insects and butterflies. flowering plants must get pollen from one flower to another flower. either within a plant for self pollination or between plants of the same species for cross-pollination to occur however Paul and cannot move on its own thank goodness she had the wind and animals in rare cases water move for plantsg it is called the pollination syndrome
Answer:
Explanation:
Gregor Mendel showed his inheritance character in the garden pea plant. According to him, there are 2 alleles which are inheritable - dominant allele and recessive allele. The dominant allele is always dominant over the recessive one which is known as the complete dominance. When the offsprings have both recessive alleles it will show its character.
There are other characters present besides dominant and recessive. Such characters are known as Mendelian deviation as it does not obey Mendel's law of inheritance. e.g. codominance, incomplete dominance.
In codominance alleles, characters are blended and a new character has seen in the next generation. This new character is neither dominant not recessive, it is an intermediate character between the 2 characters.
e.g When the white and red flowers crossed pink flowers are formed along with red and white.
In the case of codominance, both alleles express their characters. Such phenotypic characters are known as codominance because both alleles are expressed in the offsprings.
e.g. When the red and white flower plants crossed the offspring flowers are red with white spots or the white with red spots.
<span>A. Acquired traits can be passed to offspring
Jean-Baptiste Lamarck first presented his Theory of Inheritance of Acquired Characteristics in 1801. According to his theory, if an organism changes in order to adapt to its environment, the changes are passed on the organism's offspring. Some of his proposed ideas in the theory, however, were dismissed by other scientists by experimenting and studying of genetics.</span>
Answer:
Epidermis layer of the skin will be most affected and blisters indicates that dermis layer of skin has also been affected.
Explanation:
The sunlight contain ultraviolet radiations which can damage the skin. The UV radiations causes serious damages to DNA and other parts of the cells directly and also by the production of free radicals. These radiations damage the DNA and cell tries to rectify them. These damages to DNA causes problems in cell replication through errors in DNA replication. If the damage is too frequent that cell can't repair it the immune response will destroy the cell.
Epidermis is the outermost layer of skin which protect the internal cells from external damages and dermis is present beneath the epidermis and it provides nutrient rich blood to epidermis. If the UV radiations are too intense they can penetrate more deeper and can damage the dermis also.
Skin burn can occur in less than 15 minutes depending upon the intensity of UV radiation. The skin become red and blisters appeared on skin. More chronic skin burn can also cause fever, chills and even death.
