Answer: Cell walls give the leave <u>support</u> so the leaf can be in a position to capture as much sunlight as possible.
Answer:
A. The extension of Mendelian genetics comprises the codominance, incomplete dominance, polygenic inheritance, multiple alleles, lethal genes, sex lined genes, gene mapping, and others.
B. The phenomenon of incomplete dominance takes place when of both the recessive and dominant forms, no one gets expressed in the F1 generation, however, an intermediate expression is witnessed. For example, crossing red flower with the white one generates pink flowers.
On the other hand, in codominance, both the alleles get expressed, like in the blood group AB. The association of genes results in epistasis, it changes the normal dihybrid phenotypic ratio, that is, 9: 3: 3: 1 to 12: 3: 1. The genes, which suppress the others are called epistatic, while the ones, which get suppressed are known as hypostatic.
Incomplete question. The options read;
a) routine and widespread usage of thermometers starting in 1860
b) invention of the mercury thermometer by Daniel Fahrenheit in 1714
c) first temperature recording by an orbiting weather satellite in 1979
d) use of ocean-going vessels to measure marine air temperatures in 2000
Answer:
<u>b) invention of the mercury thermometer by Daniel Fahrenheit in 1714</u>
Explanation:
The definition of climate would lack proper understanding if not for the invention by Daniel Fahrenheit in 1714. Historians agree that Daniel's mercury thermometer allowed many other researchers to understand how much temperature existed in a particular environment or climate.
DNA and RNA are the genetic code. They are passed form the ancestor to offspring. They code for a mix of traits from the parents and tell the cells what to do what traits to form, and overall how to function
During meiosis, genetic recombination may occur more than once through the process of cell division, resulting in an increase in genetic variability.
