Q4: Describe how crossing over can lead to new variations in genes.
Answer:
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

A genetic experiment with peas resulted in one sample of offspring that consisted of green peas and yellow peas.444167a. Construct a %confidence interval to estimate of the percentage of yellow peas.90b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas isnot 25%, do the results contradict expectations
Answer: a.) 0.2438 < p < 0.3028
b.) No
Explanation: Confidence Interval to estimate the percentage of yellow peas is calculated following these steps:
1) Total of the offspring in one sample:
n = 444 + 167
n = 611
2) Proportion of yellow peas, which is the number of yellow peas observed divided by the total of offspring:
p = [tex]\frac{167}{611}[/tex] = 0.2733
3) For a 90% confidence interval:
α = 1 - 0.90
[tex]z_{\alpha/2}=z_{0.05}[/tex]
Checking z-table, z-score will be: z = 1.645.
4) Calculate margin of error:
[tex]E=z.\sqrt{\frac{p(1-p)}{n} }[/tex]
[tex]E=1.645.\sqrt{\frac{0.27(1-0.27)}{611} }[/tex]
E = 0.0295
5) Confidence interval has boundaries:
p - E = 0.2733 - 0.0295 = 0.2438
p + E = 0.2733 + 0.0295 = 0.3028
Then, we are 90% confident that the percentage of yellow peas is between 24.38% and 30.28%.
b.) Since 25% is in the confidence interval, and we are 90% sure the true percentage of yellow peas are inside the interval, the result does not contradict the expectations.

Directions: Drag the nitrogenous bases to the correct locations on the image. Each base can be used more than once, but not all bases must be used. A section of a DNA molecule is shown in the diagram below, but only one strand is complete. Add the correct nitrogenous bases to the molecule to form two complementary DNA strands. C T G U А TG CTC A G A C Reset Next Question
Answer:
DNA strand: TGCTCAGAC
Complementary DNA strand: ACGAGTCTG
Explanation:
Deoxyribonucleic acid (DNA) is a molecule consisting of two strands, where each strand is composed of a linear sequence of nucleotides (polynucleotide chain). Each DNA nucleotide is composed of 1-a deoxyribose sugar, 2-a phosphate group, and 3-a nitrogenous base. In DNA, there are four types of nitrogenous bases: Adenine (A), Guanine (G), Thymine, and Cytosine (C). These nucleotides are held together by hydrogen bonds in order to form the DNA double helix. By base pairing, G always pairs with C, and T always pairs with A, thereby the amount of G is equal to C and the amount of T is equal to A. In the RNA, T bases are replaced by Uracil (U) bases.

In addition to deep sea organisms, there are many species found throughout the ocean. The numbers and relative proportions of Bacteria and Archaea change with depth in response to changing conditions. Viruses that infect the prokaryotic organisms play a variety of important roles in this habitat, including control of their overall numbers and facilitation of horizontal gene transfer. Choose whether each statement best describes bacteria, archaea, or viruses.
a. Most are inactivated by hydrolytic enzymes or sunlight,
b. Turnover in seawater is relatively rapid; the populations are replaced within a few days or weeks.
c. They are the predominant prokaryotes above 1000 m.
d. Most of these living below 1000 m are thought to be ammonia oxidizers.
e. Below 1000 m the most common phylum is Thaumarchaeota.
f. They increase to near 50% of total prokaryotes below 1000 m.

Bacteria:
They are predominant prokaryotes above 1000 m. A common genus is Pelagibacter. Some types found in the photic zone carry out aerobic photosynthesis.So, the statements (c), (h), and (i) are true about bacteria.
Archaea:
Most of these living below 1000 m are thought to be ammonia oxidizers. Below 1000 m the most common phylum is Thaumarchaeota. They increase to near 50% of total prokaryotes below 1000 m.So, statements (d), (e), and (f) is true about Archaea.
Viruses:
Most are inactivated by hydrolytic enzymes or sunlight. Turnover in seawater is relatively rapid; the populations are replaced within a few days or weeks.They are the most numerous biological entities in seawater.So, statements (a), (b), and (g) are true about Viruses.

Answer:
b. synthesis of many extra secreted proteins.
c. mutation of a factor critical for degradation of proteins in the lysosome
d. mutation of a factor important for protein folding in the ER
The conditions that would activate the unfolded protein response are:
Synthesis of many extra secreted proteins.Mutation of a factor critical for degradation of proteins in the lysosome.Mutation of a factor important for protein folding in the ER. What do you mean by unfolded protein response?The unfolded protein response may be defined as a cellular stress response related to the endoplasmic reticulum stress. It is a mechanism through which the accumulation of misfolded protein is induced.
Unfolded protein response gats are activated when there is any mutation or alteration that takes place in the ER, and sometimes lysosomes. Because these are both organelles that mediate the protein trafficking throughout the cell.
Therefore, the conditions that would activate the unfolded protein response are statements (b), (c), and (d).

How does photosynthesis and cellular respiration compare to each other
Answer:
Photosynthesis takes place in the chloroplasts of cells. While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants perform both photosynthesis and respiration, while animals can only perform respiration.

Some caves are created when water dissolves limestone below ground. Which part of the water cycle is most responsible for the formation of caves?
Answer:
Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle. Condensation is the opposite of evaporation.
