Substance A's molecules are small. Substance B's molecules, which react with substance A to produce a blue-black color, are larger in comparison. If a solution of substance A is placed inside a selectively permeable bag, and the bag is placed in a solution of substance B, what will happen?
Here's link to the answer:
tinyurl.com/wpazsebu
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.
What is the reaction between the starch and the iodine?
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.

How does reproduction in yeast compare to reproduction in dairy cattle? Check the four (4) correct answers. Read them carefully!
Yeast reproduce sexually.
Cattle offspring will have more genetic variation than yeast offspring,
Cattle reproduce sexually.
Yeast inherit genetic material from one parent.
Yeast reproduce asexually
Yeast offspring will be have more genetic variation than cattle offspring.
Answer:
cattle reproduce sexually
cattle offspring will have more genetic variation than yeast offspring
yeast inherit genetic material from on parent
yeast reproduce sexually
Explanation:
The correct statements are:
Yeast reproduce both sexually and asexually, while cattle reproduce only sexually.
Cattle offspring will have more genetic variation than yeast offspring because cattle undergo meiosis, which shuffles their genetic material, while yeast can reproduce clonally through asexual reproduction or sexually through mating of haploid cells.
Yeast inherit genetic material from both parents during sexual reproduction, while in asexual reproduction they inherit genetic material only from one parent.
Yeast offspring can have more genetic variation than their parents due to recombination during sexual reproduction, while cattle offspring will have a mix of genetic material from their parents due to meiosis.
Describe yeast?Yeast is a type of single-celled microbe that is a member of the fungi kingdom. Because it is a eukaryotic creature, each of its cells contains a real nucleus as well as other organelles.
Therefore, despite the fact that both yeast and cattle are capable of sexual reproduction, the procedures and results are very different. Cattle can only reproduce sexually, although yeast can also multiply asexually.
Due of the variations in their reproductive systems, the genetic variety in progeny is likewise unique. These characteristics are not important when creating renewable energy sources because they are biological variations between species rather than technological or economical factors.

On the Indonesian island of Bali, about 3/4 of the feral (stray) cats have a stumpy tail while only 1/4 of the cats have a regular long tail. When you did some experiments and picked out a bunch of random stumpy-tailed cats and mated them, they had some stumpy-tailed kittens and some regular-tailed kittens. You did the same with the the regular tailed cats, but they always had only regular tailed kittens. What does this tell you about the genotype of the regular tailed cats
Answer:
That stumpy tail is the dominant trait, while the regular long tail is the recessive trait.

Describe the importance of a hypothesis in scientific inquiry.
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.

Which is evidence of climate-forced sea level rise?
A. decreased temperature of oceans
B. submerging of low islands and coastlines
C. temperature changes for surface currents
D. increased carbon dioxide in the atmosphere
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.
What could happen with sea level rise?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.

In a species of Drosophila, developing larva have special proteins in their epithelial cells. These proteins bind to a certain repressor in the larva's cells, which ultimately causes a dark pigment to be produced. What would you expect if scientists purposely injected a developing larva with an excess of these proteins?
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.

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:

B) is your answer.

Curly hair (C) is dominant where straight hair (c) is recessive. If a person who is Cc has children with a person that is cc, what is the probability of their children will have curly hair?
a
0%
b
25%
c
50%
d
75%
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%.
