Explanation:
In humans, brown eyes are dominant to blue eyes. If a blue-eyed man has children with a brown-eyed woman whose mother has blue eyes, what percentage of the brown-eyed offspring do you expect will be heterozygous
Answer:
50%
Explanation:
This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.
According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).
Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.
Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.
Which of the following is an example of a
homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals
Answer:
the wings on bees and birds
An example of a homologous trait is the wings of bees and birds. The correct option is A.
What are homologous traits?The Theory of Evolution can be used to explain the homologous features of related species. According to this hypothesis, species develop over time from a common progenitor.
In order to adapt to the new environment, species separated from one another and developed new features. The variety of species observed on Earth today is the result of a process known as speciation.
The homologous features that are shared by related species are proof of their shared ancestry. For instance, despite being different, the wings of a bat and a bird share characteristics.
Therefore, the correct option is A. the wings of bees and birds.

Classify these hypotheses about the ocean as falsifiable or non-falsifiable.
The hypotheses about the ocean as
Falsifiable: 1) Limestone erodes faster than basalt when exposed to ocean salt water 2) Shallower tide pools support more algae growth.
Non-falsifiable is: 1) The rugged Panama coastline offers a wonderful experience for fishing enthusiasts. 2) Warm ocean water is more enjoyable to swim in than cool ocean water.
Limestone erodes faster than basalt when exposed to ocean salt water.
This hypothesis is falsifiable. One could conduct an experiment in which samples of limestone and basalt are exposed to ocean salt water and the rate of erosion is measured and compared between the two samples.
The rugged Panama coastline offers a wonderful experience for fishing enthusiasts.
This hypothesis is non-falsifiable. The statement is subjective and cannot be tested or proven true or false. What one person considers a wonderful fishing experience may not be the same for another person.

A tube with a membrane covering the bottom is placed in a beaker. The membrane allows water to flow through but not salt or glucose. The tube contains an aqueous solution with 4% salt and 20% glucose and the beaker contains an aqueous solution with 12% salt and 6% glucose. How could you describe the solution in the beaker compared to the solution in the tube
Answer:
The solution in the tube is hypertonic to the solution in the beaker.
Explanation:
To compare the solutions, find the total amount of solutes in both the tube and beaker.
The tube has 4% salt and 20% glucose, so it has 24% solute.
The beaker has 12% salt and 6% glucose, so it has 18% solute.
Since 24 is larger than 18, this means the tube has more solute.
Since the tube has more solute and less water compared to the beaker, it is hypertonic to the beaker.
So, the answer is that the solution in the tube is hypertonic to the solution in the beaker.
Solutions are hypertonic or hypotonic to other solutions according to their solute concentration grade. In the exposed example, the beaker aqueous solution is hypotonic to the tube solution, meaning it is less concentrated.
--------------------
Available data:
The membrane allows water to flow through but not salt or glucoseThe tube contains an aqueous solution with 4% salt and 20% glucoseThe beaker contains an aqueous solution with 12% salt and 6% glucoseWe need to describe and compare solutions.
To do it, first, we will review some theoretical framework.
When talking about solutions in compartison with the cell content, we can classify them as follows,
• HYPERTONIC ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself.
• ISOTONIC ⇒ The solute concentration is the same inside the cell and outside.
• HYPOTONIC ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.
When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the tube and the beaker- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
What we need to consider is
• When a cell with semipermeable membrane is placed in a hypotonic solution, water enters the cell.
• When a cell with semipermeable membrane is placed in an isotonic solution, there is no water movement.
• When a cell with semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.
In simple words, in the proposed experiment, glucose and salt -solutes- can not cross the membrane, but water can. The tube represents a cell. So,
The tube has 4% salt and the beaker 12 % saltThe tube has 20% glucose and the beaker 6% glucose.To make the analysis easier, we can add the concentration percentages of glucose and salt at each side of the membrane, and then compare them.
The tube contains an aqueous solution with 24% solute (4% salt + 20% glucose)The beacker contains an aqueous solution with 18% solute (12% salt + 6% glucose)We can see that the concentration of solute is higher in the interior of the tube than in the beaker. This difference suggests that water will move forward to the tube interior.
According to this analysis, we can say that
The tube aqueous solution is hypertonic to the beaker solution → More concentratedThe beaker aqueous solution is hypotonic to the tube solution → Less concentrated---------------------------------------------

why is rna a polymer and a macromolecule
Answer:
RNA is a polymer because it is made up of many monomers called nucleotides. Moreover, RNAs can form macromolecules because many RNAs are large molecules (i.e., polynucleotide chains).
Explanation:
Ribonucleic acid (RNA) can be defined as a single-stranded nucleic acid polymer of the four nucleotides. In RNA, each nucleotide is composed of a 1-ribose sugar, a 2-phosphate group and 3-one of four types of nitrogenous bases: Adenine (A), Cytosine (C), Guanine (G), and Uracil (U), which are covalently bonded to form polynucleotide chains. There are different types of RNAs such as mRNA, tRNA, rRNA, miRNA, circ-RNAs, lncRNAs, etc. Many of these RNAs form large single-stranded (ss) molecules, i.e., polynucleotide chains. For example, an mRNA sequence may have a length of 5,000 nucleotides (5 kb) or even more, and there are RNA viruses that have more than 20000 nucleotides (20 kb) in length.
