Answer:
According to neuroscientists, everything we perceive is a construction of the brain, thus, human perception is largely a linguistic and cultural process that assigns meaning to the millions of sensations we encounter daily.
Explanation:
Answer:
c.1 pink:1 white
Explanation:
Incomplete dominance is a genetic phenomenon whereby one allele of a gene is not completely dominant over the other allele, hence, it forms an heterozygous with an intermediate phenotype different from both parents. In this case of snapdragon plants, CRCR is the red allele while CWCW is the white allele. They form an intermediate phenotype that has pink flower colour; CRCW.
Hence, in a cross between a pink snapdragon (CRCW) and a white snapdragon (CWCW), four possible offsprings will be produced with two distinct genotypes: CRCW (2) and CWCW (2). Hence, this will give a ratio of 2:2 or 1:1 consisting of 1 pink : 1 white offspring.
Answer:
d They usually have certain special functions
Explanation:
a) They can all turn into the same kind of cell needed - this is false. Cells in a multi cell organism such as humans cannot turn to any type of cell, this functionality is called pluripotency, and only exists in specialised cells called stem cells. These cells are present early in development, and in some tissues where cells are replaced frequently, like the cells of the gut.
b) They are all identical - this is false. Although they all carry the same genetic information, the cells in a multicell organism are usually very different, carrying out different functions. E.g. the cells of the skin are very different from the cells of the blood.
c) They are prokaryotic cells - this is false. All prokaryotic cells are single celled organisms, only eukaryotic cells can form part of multi cell organisms
d) They usually have certain special functions - this is true. Cells in a multicell organism usually perform different functions in order to contribute to the entire organism. For example, the function of the cells in the heart is very different from the function of the cells in the brain.
