17. In Gregor Mendel's first experiment, he created a plant with purple flowers (PP , two dominant traits) with a plant with white flowers (pp , two recessive traits). What were the results of his experiment:

[tex]\left[\begin{array}{ccc}&P&P\\p&Pp&Pp\\p&Pp&Pp\end{array}\right][/tex]

a. 100% purple is your answer. Note that if there is a dominant trait, the dominant trait will show. In this case, purple is the dominant trait P, and is located on all quadrants, therefore 100% purple is your answer.

18. In Mendel's second experiment, he uses two purple flowers (Pp , one dominant, one recessive, each respectively). What were the result of his experiment:

[tex]\left[\begin{array}{ccc}&P&p\\P&PP&Pp\\p&Pp&pp\end{array}\right][/tex]

d. 75% purple, 25% white is your answer. The dominant trait P is found in three quadrants, with only the bottom right quadrant having two recessive trait p. This means that the quadrant with pp is white, and the others are purple.

19. Note that the Bob's dimples (DD) are the dominant trait, while Janet has the recessive traits (dd). Set the Punnett Square:

[tex]\left[\begin{array}{ccc}&D&D\\d&Dd&Dd\\d&Dd&Dd\end{array}\right][/tex]

d. 100%. In this case, the dominant trait shows up in all 4 quadrants, and will therefore mean that their child will have dimples. However, they will carry the recessive trait.

20. Matt and Meredith both have dominant brown eyes, but their daughter has blue eyes. This means that they both are carriers of a recessive blue strand (denoted by b.) This means that both Matt and Meredith are Bb. Set the Punnett Square:

[tex]\left[\begin{array}{ccc}&B&b\\B&BB&Bb\\b&Bb&bb\end{array}\right][/tex]

B) is your answer.

Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms that reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.

This is what I found during my research and I hope this helped somehow. Have a good one!

Explanation:

In this exercise we have to use the knowledge of climate changes that demonstrate the increase in the sea level, in this way we have that:

The submerging of low islands and coastlines or letter B.

The rise in sea level caused by global warming could reach 2 meters in height by the end of the 21st century. This rise in the oceans would leave thousands of kilometers of coastline at the mercy of flooding, jeopardizing the safety of 745 million people worldwide.

The recent rise in sea level is a result of global warming through two main processes: expansion of sea water due to warming of the oceans, triggering its thermal expansion, and the melting of ice masses.

Answer:

The larva gets dark pigment.

Explanation:

If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.

Answer:

1- DNA replication: two identical DNA strands

2- Transcription: mRNA

3-Translation: proteins

4- Mitosis: two identical diploid somatic cells

5- Meiosis: four different haploid gamete cells

Explanation:

1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created

2- Transcription: the process by which DNA becomes mRNA

3-Translation: the process by which mRNA becomes proteins

4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells

5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells

Beaker A= Isotonic

Beaker B = Hypotonic

Beaker C= Hypertonic

Explanation:

ISO means the same on each side.

Hypo means less.

Hyper means more.

Beaker A= Isotonic

Beaker B = Hypotonic

Beaker C= Hypertonic

The main difference between isotonic hypotonic and hypertonic solutions is that isotonic solutions are solutions having equal osmotic pressures while hypotonic solutions are solutions having lower osmotic pressure and hypertonic solutions are solutions with high osmotic pressure.

TGAATGCGGCTA

Explanation:

The complementary DNA codes for A is T and for G its C

Answer:

TGAATGCGGCTA

Explanation:

Remember these are the complementary dna base pairs

adenine with thymine

thymine with adenine

cytosine with guanine

guanine with cytosine

so a would change to t

c to g

t to a

etc

after pairing each letter we would end up with

When A reacts with B, it turns blue-black because the substance A is starch and its molecules are small, which is glucose. The substance B is iodine, which combines with starch to become blue black. If A is present in B, then the A will become blue black.

Starch is a polymer that is made up of glucose monomer and is found in plant-based food products. This starch can react with iodine and produce a blue-black coloration, so when the substance A is placed in the substance B with a selectively permeable membrane, the substance B (iodine) can easily enter the starch and form the blue-black coloration. This is known as the starch-iodine reaction, and it results in a blue-black polysaccharide.

Hence, if a solution of substance A is placed inside a selectively permeable bag and the bag is placed in a solution of substance B, then the substance A (starch) will turn blue-black.

Answer: c. 50%

Explanation:

If you draw a punnett square you see that the phenotypes you get are Cc, Cc, cc, and cc. If C (curly hair) is dominant over c (straight hair) then those with the phenotype Cc would have curly hair and those with the phenotype cc would have straight hair. 2 out of 4 have Cc (curly hair) so that's 50%.

Answer:

1) Structural proteins provide support in our bodies, for example, the proteins in our connective tissues, such as collagen and elastin.

2) Hormone proteins co-ordinate bodily functions, for example, insulin controls our blood sugar concentration by regulating the uptake of glucose into cells.

Answer:

The fundamental concept of a theory is that there is no predetermined conclusion. A main feature of this phase of the experimental process is deriving conclusions from theories regarding the outcomes of possible studies and then conducting certain experiments to see if the predictions are supported.

Explanation:

A hypothesis is crucial in scientific inquiry as it serves as a testable and falsifiable explanation or prediction for a specific phenomenon or observation.

It provides a structured approach to investigating a research question and guides the design of experiments and data collection.

By formulating a hypothesis, researchers set a clear direction for their study and establish a basis for drawing conclusions based on evidence.

If the hypothesis is supported by data, it strengthens the understanding of the subject matter.

Alternatively, if the data refute the hypothesis, it encourages further exploration and refinement of scientific knowledge, promoting the advancement of understanding and discoveries in various fields.
