Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting.
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
The answer is 0.43
To calculate p we will use one of two formulas of the <span>Hardy-Weinberg principle:
</span>
p² + 2pq + q² = 1 and <u>p
+ q = 1</u>
where:
p - the frequency of the allele for long legs which is a dominant trait.
q - the frequency of the allele for short legs which is a recessive trait.
p² - the frequency of dominant homozygote (with long legs)
2pq - the frequency of heterozygote (with long legs)
q² - the frequency of recessive homozygote (with short legs)
So, 33 of 100 organisms have short legs. The frequency of recessive homozygote is represented by q²:
<span>q² = 33/100 = 0.33</span>
⇒ q = √0.33 = 0.57<span>
</span>
Using the formula:
p + q = 1
p = 1 - q = 1 - 0.57 = 0.43
Therefore, p = 0.43
The correct answer is :
Some substances but not other can cross the (blank ) membrane of a cell. The blank is to be filled with either cell or plasma. Cell membrane or plasma membrane is the living boundary of a cell which is made of phospholipid. It is a semi-permeable or differentially permeable membrane. It only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it
