In this case, we have a double-cross between a dominant homozygous for both traits and a recessive heterozygous. According to the exercise we have red for dominant (R) white for recessive (w), tal dominant (T), and short recessive (t). So the parents are as follows

Red tall homozygous (RRTT)

White tal heterozygous (wwTt)

We obtain gametes for each parent

Now we obtain the punnet square

Now we obtain frequencies

Genotypes:

Red heterozygous tall homozygous RwTT: 8/16= 50%

Red heterozygous tall heterozygous RwTt: 8/16= 50%

Phenotypes:

Red tall 16/16=100%

Now the gardener would never obtain red short flowers because there is none recessive homozygous for height trait.

The biggest barrier to underwater exploration is the rise in pressure with increasing water depth. A person would pass out from increased pressure at such a deep depth of water (lose consciousness).

Drilling-assisted ground water exploration is one of the Central Ground Water Board's (CGWB) main tasks, with the goal of finding aquifers in various hydrogeological settings and establishing hydraulic characteristics.

In order to comprehend the hydrologic cycle, know the quality of the groundwater, and determine the nature, quantity, and type of aquifers, groundwater exploration is the research of subsurface formations.

In this case, we can see that the environment is exerting a selective pressure over a certain phenotype, that is short wings, it does not say if medium wings are thriving in this environment or not, however, we know that those with long wings are having difficulties meanwhile short wings are successful, therefore we can see that this is selection.

The level of organization associated with amino acid order is primary (option B).

The secondary level of organization describes how this amino acid chain is folded, the most common organization srtuctures are alpha helix or betta sheet.

Tertiary level of organization is the result of interaction between secondary structures.

Lastly, quartinary level of organization is about interactions between peptides (other amino acid chain).

Enzymes are said to be specific because an enzyme binds to only one or one group of substrates for its activity.

The enzyme's specificity is a property that indicates how restricted the enzyme is in its substrate selection; There would only be one substrate for a completely unique enzyme. Specificity is the capacity of an enzyme to select a specific substrate from a variety of chemically similar compounds. Specificity is a molecular identification process due to the complementary structural and conformational properties of the enzyme and substrate. Since the specific substrate must fit into the enzyme's active site before catalysis can take place, only well-designed molecules can be enzyme substrates; An enzyme will frequently react with a single naturally occurring molecule or substrate.

Answer:

The mother has a genotype of aa, the father has a genotype of Aa and the child has a genotype of aa.

Explanation: If the couple decides to have more children the children would have a 50% 50% chance of being albino.  Every child they have will be a carrier of the recessive gene gained from their mother. The children would either have a genotype of Aa or aa. Also, the father has a heterozygous genotype. He also is a carrier of the recessive gene since their first child was albino.  You cannot be made albino unless both alleles from your parents are recessive and even though the father is not albino (because he had the dominant allele A), he had an albino child therefore making him a carrier of the allele a.

The cell membrane sticks right up against the cell wall when the turgor pressure is high. In this situation, it is hard to distinguish the two structures because they are so close. However, during plasmolysis, the cell membrane is extremely removed from the cell wall and is easy to distinguish

The moment of a system results from adding the vectorial moments of each object composing the system. According to the law of conservation of momentum, the initial moment is equal to the final moment. D) -31 kg m/s.

First, let us remember that momentum or lineal momentum is a motion quantity. In physics, it is the fundamental quantity that characterizes the motion of any object.

The momentum is a vectorial quantity calculated as the product of the object mass by its lineal velocity ⇒ mv.

The total lineal moment of a system constituted by a group of objects, is the sum of the vectorial moments of each of the objects.

In an isolated system (like crushes, explosions, and collisions), the moment remains constant through time. This is the law of conservation of momentum. The initial moment is equal to the final moment ⇒ Pinitial = Pfinal

In the exposed example,

121 kgm/s + (-80 kgm/s) = P initial

72 kg m/s + X = P final

Pinitial = Pfinal

121 kgm/s + (-80 kgm/s) = 72 kg m/s + X

Now, we just need to clear X to determine the momentum of the quarterback after the collision.

121 kgm/s - 80 kgm/s - 72 kgm/s = X

121 kgm/s - 80 kgm/s - 72 kgm/s = - 31 kgm/s

Option D is correct.

Mucosa-associated lymphoid tissue (MALT) is least associated with (b) Erythropoiesis.

A network of lymphoid cells aggregates, and the tissue known as mucosa-associated lymphoid tissue (MALT) is found in the submucosal layers of the gastrointestinal, vaginal, respiratory, and urinary tracts, as well as the skin, tonsils, eyes, thyroid, breasts, and salivary glands. MALT (mucosa-associated lymphoid tissue) stimulates immunological responses to antigens encountered throughout all mucosal surfaces. Secondary immune tissues called MALT inductive sites serve as locations for antigen collection and the onset of immunological reactions.

Erythropoiesis is the production of red blood cells. It is the development of erythropoietic stem cells into mature RBCs stimulated by a decrease in the oxygen level in circulation detected by the kidneys, which then secretes the erythropoietin hormone. Thus, MALT is least associated with erythropoiesis.

Independent Assortment, Random Fertilization and recombination takes place during  Metaphase I and Prophase I. Therefore, option (D) is correct.

Prophase I is when recombination or crossing across happens. Gene by gene, identical chromosomes—1 from each parent—pair along their lengths. Chromosomes break along their length, reunite, and exchange some of their genes. The chromosomes now contain a distinctive collection of genes. This causes genetic variation.

Random Fertilization and Independent Assortment in Metaphase I

Meselson-Stahl's experiment contributed to our understanding of DNA replication because the use of radioactive nucleotides showed that one DNA strand is synthesized in each round of replication while the other chain remains unchanged, which is known as semiconservative replication.

In genetics, semiconservative replication refers to the process by which DNA is duplicated during the process of DNA replication. In semiconservative replication, one DNA chain is conserved in intact conditions while the other one is synthesized in the final double helix DNA molecule.

Meselson-Stahl's experiment contributed to the discovery of the semiconservative nature of DNA replication by observing that only one radioactive chain was added to each round of replication.

Therefore, with this data, we can see that the semiconservative replication of the double helix DNA molecule is a fundamental process associated with DNA replication which was discovered by Meselson-Stahl's experiments.
