Students are asked to pair a plant structure to its physiological function as well as give evidence for why
that structure is important for the process they describe.
• Shantal: The cambium are important for photosynthesis because they allow water into the plant
which is needed as a reactant for photosynthesis.
• Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves
in order to perform cellular respiration.
• Enrique: The guard cells are needed during food production because they regulate how much water
the plant retains or loses during glycolysis.
• Anne: The seeds of the plant are needed for reproductive purposes and they can be dispersed or
spread out over a large area.
Which student correctly described a plant structure, its physiological function, and gave appropriate
evidence?
O Shantal
O Jamil
O Enrique
O Anne
Answer:
Anne
Explanation:
The only student that correctly described a plant structure, its physiological functions, and gave appropriate evidence is Anne.
The seeds of plants are propagules and, depending on the kind of seed, can be dispersed over a large area from their parent plants.
The phloem of a plant is primarily concerned with the conduction of synthesized food around the body of the plant from the source of production. Hence, Jamil's description that the phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves was inaccurate.
The guard cells control the rate of evapotranspiration of water from the plant but have nothing to do with the breakdown of glucose, also known as glycolysis. Thus, Enrique's assertion was also inaccurate.

The sequence of bases on one strand of a DNA molecule is AGT GTA GAC. After replication of the strand of DNA, what is the sequence of nitrogen bases on the complementary (opposite)strand?
Answer:
TCA CAT CTG
Explanation:
If there is an A, then on the complementary strnad there will be a T (and vice versa) since Adenine (A) always bonds with Thymine (T)
If there is an C, then on the complementary strnad there will be a G (and vice versa) since Cytosine (C) always bonds with Guanine (G)
The sequence of nitrogen bases on the complementary (opposite) strand is TCA CAT CTG
What are complementary strands of DNA?Complementary strand is either of the two chains that make up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.
The complementary strand for DNA must follow the base pairing and polarity rules. Pairing means that A=T and G=C. Polarity means that the strands have to run in opposite directions.
The upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA.

All the offspring will show the dominant trait
About 50% of the offspring will show the recessive trait
About 75% of the offspring will show the dominant trait
Answer:
Explanation:
A
Assume that (B) genotype is dominant and (b) genotype is recessive: bb mates with bb. All the offspring will show the recessive trait. thus option A is correct.
What is genotype ?A genotype can be defined as the total set of heritable characters carrying genes transferred from parents to offspring; These genes involve in encoding specific features that can be physically expressed in an organism called as phenotype.
The genotypes of the gene can be represented in three form on the basis of allele arrangement such as homozygous dominant (PP), Heterozygous (Pp) and Homozygous recessive (pp).
genotyping is a method is used to determine the genotype of an individual by using biological assay and the techniques used are, DNA fragment analysis, PCR, allele-specific oligonucleotide (ASO) probes, nucleic acid hybridization, DNA microarrays or beads, and DNA sequencing.

If The RNA strand is AUG, what is the protein it produces.
Answer:
methionine
Explanation:
According to the codon chart (see the attached image), the RNA strand AUG will produce methionine as its translation product during the process of protein sysnthesis.
The table of codons is a chart that shows how genetic codes are translated into their respective amino acids during protein synthesis. The AUG codon also represents a signifier of the beginning of the translation process apart from coding for methionine.

Human p53 is a tumor-suppressor gene located on chromosome 17. The function of this gene is to prevent cells with damaged DNA from undergoing mitosis. What would most likely result if there were a mutation that decreased the function of the p53 gene?
The answer is “Germs cells would undergo only one meiotic division.
Explanation:
I remember learning this in my biology class
Single amino acid changes in p53 caused by TP53 gene mutations make the protein less functional. Without p53, cell proliferation is not efficiently controlled, and DNA damage can build up in cells.
How p53 gene is important?Such cells might continue to divide uncontrollably, which would promote the development of tumors. By stopping the cell cycle to give the repair mechanisms time to restore genomic stability, p53 plays a significant function as a DNA repair facilitator.
Additionally, p53 adopted a variety of roles to directly influence the operation of different DNA-repair mechanisms.
Cancer cells may develop and spread throughout the body as a result of mutations (changes) in the p53 gene.
Therefore, numerous cancer kinds and the genetic disorder Li-Fraumeni syndrome have both been linked to these alterations.

Explain how the geologic time scale is used to organize Earth’s history.
Think about how the geologic time scale was created and how it is divided. Then answer the following questions.
How did scientists from the geologic time scale?
How is this scale organized?
What processes changed the Earth's environment during Precambrian time?
Answer:
The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.
Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.
The first principle you need to understand about geologic time is that the laws of nature are always the same.
What is the Time scale?Water, for instance, freezes at 0°C. This rule has held and will continue to hold forever.
Understanding natural principles facilitate historical thinking because it provides hints about how things were very long ago. It implies that we can interpret the past using current methods.
The rock must have formed close to the sea because this law has never changed.
Therefore, The first principle you need to understand about geologic time is that the laws of nature are always the same.
