The FOIL method is used to multiply binomials, or to multiply (x + 3) by (3x -12) for example. Then multiply the OUTSIDE terms together, or x and -12 to get -12x. Then multiply the INSIDE terms together, or 3 and 3x to get 9x. The multiply the LAST terms together, or 3 and -12 to get -36.
<span>The urinary system, also known as renal system, eliminates the majority of nitrogen-containing metabolic waste products. It
</span><span> is a group of organs which filters out excess fluid and other substances from the bloodstream. The organs that compose the urinary system are: </span> kidneys, ureters, bladder, and the urethra. The result is <span>stable balance of salts and other substances in the blood.</span>
The answer is <span>D- thigmotropism
</span>
Tropism is plant growth in a response to a stimulus.
Through the process of elimination:
A - phototropism is plant growth in a response to light.
B - Photoperiodism is an organism reaction to the lengths of days and nights.
C - Gravitropism is plant growth in a response to gravity.
D - Thigmotropism is plant growth in a response to contact
Since <span>a grapevine makes a contact with a fence, this is an example of thigmotropism.</span>
Answer: Base pairs occur when nitrogenous bases make hydrogen bonds with each other.
Explanation: Each base has a specific partner: guanine with cytosine, adenine with thymine (in DNA), The hydrogen bonds are weak allowing it to "unzip"
Random orientation of homologous pairs of chromosomes during meiosis I results in alternative arrangements that contribute to genetic variation in offspring. This is called "independent assortment".
<u>Explanation:</u>
The sets of homologous chromosomes, also recognized as bivalents or tetrads, align along the metaphase plate in a random order in metaphase I of meiosis I. Another way for cells to incorporate genetic variation is by spontaneous orientation. Mendel's independent assortment law stipulates that, independently of one another, the alleles of two or more different genes are sorted into gamets.
In other terms, for one gene, the allele that a gamete receives does not affect the allele that is obtained for another.Genetic recombination (by random segregation) and crossing over during meiosis creates daughter cells each containing different combinations of maternally and paternally coded genes.
