Explanation:
in a punnett square the alleles of all the male gametes are entered in the
a. top of the chart
b. right column
c. left column
d. bottom left box
Answer:
In a Punnett's square the alleles of all the male gametes are entered in the top of the chart (option a).
Explanation:
Punnett square was designed to plot the allele crosses of the parental generation and observe the probable combinations of the alleles in the offspring, for a given characteristic.
Conventionally, in a Punnett square or chart, the father's alleles are placed at the top, the mother's alleles are placed in the left column and the results in the offspring are shown in the boxes, resulting from the intersection of the data.

Question 10 of 10
Which process takes place first in the development of a human being?
O A. Fertilization
O B. Embryo formation
C. Differentiation
O D. Blastocyst formation
Answer:
A. Fertilization
Explanation:
The development of a human being begins with fertilization, a process by which two highly specialized cells, the spermatozoon from the male and the oocyte from the female, unite to give rise to a new organism, the zygote.
In humans, albinism is recessive to pigmented skin. Suppose an albino man
marries a normal woman whose father is albino. Perform a Punnett square for the
crossing between the woman and her husband using the letter a (show your work).
What is the:
a) genotypic ratio of their offspring?
b) phenotypic ratio of their offspring?
Answer:
the offspring has equal chances of being albino or normal. The offspring have equal chances of having albino or normal genotype
Explain how signaling pathways are deactivated for transduction parts of a signaling pathway.
Explanation:
cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response. cAMP signaling is turned off by enzymes called phosphodiesterases, which break the ring of cAMP and turn it into adenosine monophosphate (AMP).
What is true about the two daughter cells formed after the binary fission of a bacterium cell?
1.They have variations in the primary DNA but have the same set of plasmids.
2.They have variations in the primary DNA but may have a different set of plasmids.
3.They have the same primary DNA and the same set of plasmids.
4.They have the same primary DNA but may have different plasmids.
Answer:
They have the same primary DNA but may have different plasmids.
Explanation:
i took a test and got the question right
The option that's true about the two daughter cells formed after the binary fission of a bacterium cell is D. They have the same primary DNA but may have different plasmids.
Binary fission simply means asexual reproduction when a body is separated into two different bodies.
It should be noted that during binary fission, the genetic material of an organism is duplicated and this enables the two new organisms formed to be able to have their separate copy of DNA.
In a bacterium cell, when the two daughter cells are formed after the binary fission, they have the same primary DNA but may have different plasmids.

7. How does the plant lichen quicken the weathering process? *
(1 Punto)
They eat the rocks
They create new bacteria that breaks away rocks
They secrete acid that breaks away rocks
They eat the acid in rocks
Answer:
The correct answer is - They secrete acid that breaks away rocks
Explanation:
Lichen causes chemical weathering to break the rocks quickly which is the excretion of various acids like oxalic acid and many more organic acids that can cause a significant impact on the rock by dissolving minerals.
By breaking the rocks it forms the ground for the plant that will come later in place of the bare rocks by this chemical weathering process. An example of chemical weather is a change of the granite to clay with the help of hydrolysis.
Which type of cells contain a cell wall?
Answer:
A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.
Explanation:
In the analysis of quantitative traits, positions on chromosomes called quantitative trait loci (QTLs) are often discussed. In the same context, restriction fragment length polymorphisms (RFLPs) are also discussed. What is the relationship between QTLs and RFLPs
Answer:
RFLP technique can be used to develop useful polymorphic molecular markers for mapping QTLs.
Explanation:
A quantitative trait locus (QTL) is a fragment of DNA whose variation is associated with phenotypic traits controlled by numerous genes (i.e., quantitative traits) such as, for example, height, weight, etc. Restriction fragment length polymorphism (RFLP) is a technique useful to detect DNA polymorphisms (i.e., genetic variation) among samples. In RFLP, the genome is digested using restriction enzymes and these restriction fragments are subsequently separated by electrophoresis depending on their size, thereby producing differential gel bands among samples. These polymorphisms can be used to map QTLs and develop linkage maps, which is known as RFLP mapping.
Rhonda visits her MD because she is feeling constantly tired. After a thorough case
history involving questions about her diet, her MD takes a blood sample. Results
indicate that her hemoglobin level is at 7g/100ml of blood (normal levels are 12-

a) What condition might Rhonda have ?
b) Why would Rhonda's low hemoglobin level cause her to feel tired ?
c) Rhonda's MD asked about iron intake (eg. from meat) in her diet? Explain why.

Answer:
When it splits it divides, therefore, the answer to this problem is B. Cell Division
Explanation:
Good luck on your test!
The part of the cell cycle which is shown in the model is best described as completing cell division.
What is cell division?This is the process which involves parent cells dividing into two or more daughter cells.

Coding of a Polypeptide by Duplex DNA The template strand of a segment of double-helical DNA contains the sequence (59)CTTAACACCCCTGACTTCGCGCCGTCG(39) (a) What is the base sequence of the mRNA that can be transcribed from this strand
Answer:
GAAUUGUGGGGACUGAAGCGCGGCAGC
Explanation:
The process whereby a mRNA molecule is formed from a DNA template is called TRANSCRIPTION. The mRNA formation follows the complementary base pairing rule which says that Adenine is bonded to Thymine (Uracil in RNA) i.e A-T(U) while Guanine is bonded to Cytosine i.e. G-C.
Based on this, a DNA molecule with base sequence: CTTAACACCCCTGACTTCGCGCCGTCG will be transcribed into a mRNA strand with base sequence: GAAUUGUGGGGACUGAAGCGCGGCAGC
