In Mendel’s garden, there were only either tall pea plants or short pea plants. How does this go against the widely accepted blending inheritance hypothesis?
Answer:
Mendel noticed plants in his own garden that weren't a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory.

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.

Question:
Chromosomes are distributed randomly during anaphase I. What are the possible chromosome combinations in the two daughter cells? (Use the following abbreviations for the chromosomes. Dark green -> DG; Light green -> LG; Dark purple-> DP, Light purple -> LP)
How does the random lining up of the homologous chromosome in Metaphase 1 contribute to Genetic Variation?
Answer:
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LPThe random arrangement of tetrads is different in every cell going through the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is different and depends on the chromosomes that form that cell.
Explanation:
1) During meiosis, organisms can produce at least four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations in the two daughter cells of the exposed example are
LG,LP + DG,DP LG,DP + DG,LP2) Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LP
The random arrangement of tetrads is different in every cell browsing the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it.
Anaphase I
Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the amount of variations in each cell is different and depends on the chromosomes that form that cell.
During meiosis, organisms can produce a minimum of four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations within the two daughter cells of the exposed example are-
LG,LP + DG,DP LG,DP + DG,LP
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
Metaphase I
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles.
The random arrangement of tetrads is different in every cell browsing the meiosis process. There is no equal alinement between the two cells.
When tetrads aline within the equatorial plane, there's no predetermined order for every one of the homologous chromosomes of every tetrad to face one among the poles then migrate to it while separating.
Any chromosome of the homologous pair might face any of the poles then migrate thereto. Each of the chromosomes has two possibilities for orientation at the plane.
When the new haploid cells are formed, the amount of variations in each cell is additionally different and depends on the chromosomes that form that cell.
This random order within the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get an equivalent genetic charge.
Therefore,the combinations of two daughter cells LG,LP + DG,DP and LG,DP + DG,LP.

Why might there be a competitive advantage to having a different flight initiation distance
when a bird is incubating eggs
Answer: The birds can perceive any kind of danger which can harm the eggs after laying.
Explanation:
The birds show response towards the other stimulus around them like weather conditions like excessive heat and rain and predators. Also they can sense the danger of damage to eggs by fellow members of the species. The distance at which the birds fly from the danger is the flight initiation distance. It is the separation distance from any kind of danger or disturbance and birds cross this distance before incubating their eggs. This is an competitive advantage with that of other members of the species as the bird will able to give birth to new ones and its population will increase in number, so the chances of reproduction and survival increases in this case.

1. How does base pairing differ in RNA, compared to DNA?
A: A pairs with U
B: T pairs with U
C: U pairs with G
D: U pairs with C
Answer:
A. A pairs with U
Explanation:
In DNA, the nitrogenous bases are A, T, G, and C. In RNA, the nitrogenous bases are A, U, G, and C.
A pairs with U in RNA because it requires less energy to use uracil over thymine.
Hope that helps.
The base pairing in RNA is different from DNA as A pairs with U.
What is DNA?DNA exists abbreviation of deoxyribonucleic acid, an organic chemical of complex molecular structure that exists found in all prokaryotic and eukaryotic cells and numerous viruses. DNA codes genetic information for the information of inherited traits. Each strand of a DNA molecule exists comprised of a long chain of monomer nucleotides. The nucleotides of DNA consist of a deoxyribose sugar molecule to which stands connected a phosphate group and one of four nitrogenous bases.
Hence, The base pairing in RNA is different from DNA as A pairs with U.

What are different types of rocks?The combination of minerals whose properties result from the combination of all the aggregate minerals are called rocks. Rocks are categorized into different types depending on various properties.
Some of them are mineral composition, chemical composition, texture etc. The three categories of rocks are most commonly known.
These are Igneous rocks, Sedimentary rocks and Metamorphic rocks. The Igneous rocks are formed when the lava or magma from the volcanoes are cooled and solidified.
The continuous deposition of materials in water bodies results in the formation of Sedimentary rocks. This process is called sedimentation.
Metamorphic rocks are formed under the surface of earth when materials are deposited and subject to high temperatures and pressure. This process is called metamorphism.
Therefore the correct option is A.

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.
