When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?

Answers

Answer 1

Answer:

The new solution has a higher concentration than the isotonic saline solution

Explanation:

Here, we want to deduce what has happened in the question.

We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.

Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.

What has occurred is the process of Osmosis

Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.

So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

11. An individual who is heterozygous for rob(13;14) is at increased risk for having a child affected by Patau syndrome. Please briefly explain why.

Answers

Answer:

because of Chromosome-13 rearranges with with other chromosome.

Explanation:

To understand and be and be able to solve or tackle this question effectively, there is need to know the meaning of the important terms in this question/problem.

- Robertsonian translocation: The term "Robertsonian translocation" simply refer to some kind of disorder in the chromosome in which a different kind of chromosome attach itself to another kind of chromosome, that is to say we have more than two fusion of chromosome that are different on chromosome 13, 14,15,21 and 22.

- Patau syndrome: The syndrome known as " Patau syndrome" is also refer to as Trisomy 13. The syndrome is a kind of abnormalities on the 13th chromosome known as chromosome 13. Patau syndrome patient will have more than two[usually three] kinds of chromosome.  

"An individual who is heterozygous for rob(13;14) is at increased risk for having a child affected by Patau syndrome. " is TRUE

A defect in  chromosome 13, that is to say the Robertsonian translocation on the 13th chromosome is what causes Patau syndrome. The Robertsonian translocation occurs by addition and subtraction of chromosomes, when there is addition on chromosome 13 or say the rearrangement of chromosome-13  with other chromosome, then, the individual's offspring has the tendency of developing Patau Syndrome.

How do your interactions with nonliving systems affect your environment?​

Answers

Answer:

Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. These living things interact with the nonliving things around them such as sunlight, temperature, water, and soil.

Explanation:

Nonliving factors determine what living things can be supported in an ecosystem. The living creatures in a habitat affect the nonliving elements within the community. For example, plants can affect soil chemistry or certain algae can influence water chemistry.

Carbon is getting stuck in reservoirs (atmosphere and ocean) which is leading to climate
change. Which of the following is not a reason for this issue?
O Decrease in plants means more carbon in the atmosphere
Increase in plants means more carbon in the atmosphere
O Less organisms in the oceans prolongs decomposition trapping carbon in the ocean
O Increased use of factories and burining of fossil fuels increases amount of carbon in the
atmosphere

Answers

Answer:

Increase in plants means more carbon in the atmosphere

Explanation:

The second option is not a reason for the issue. This is because plants remove carbon from the atmosphere for their life processes.

During the process of photosynthesis, green plants manufacture their food in the presence of sunlight using water and carbon dioxide.

Plants do not trap carbon. They ensure the movement of carbon in nature. Other choices shows how carbon get trapped in the atmosphere and ocean.

Answers

Answer:

C

Explanation:

The most obvious sign of cluster distribution in termites is they are social insects. The correct option is c.

What is cluster distribution?

In cluster sampling, a population is divided into clusters, which are smaller groups. They then choose a sample at random from these clusters. Often employed to investigate huge populations, particularly those that are extensively geographically distributed, cluster sampling is a probability sampling technique.

Termite colonies can contain anywhere between 100 and 1,000 individuals, with the larger species typically having a larger colony size. However, some termite colonies, including those with a large population, can reach millions of members.

Therefore, the correct option is c. They are social insects.

Which of the following is not a step in the process of natural selection

B. Members of a population possess heritable variations.

C. People select which individuals breed and which ones do not.

D. Over multiple generations of reproducing, a larger proportion of the population will have those favorable traits and thus adaptation has occurred.

F. The population produces more offspring than the environment can support.

Answers

Answer:

A step that is not part of natural selection is people select which individuals breed and which ones do not.

Explanation:

Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.

As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that people cannot determine which individuals breed.

Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.

The other options do form part of natural selection, since they are based on the three premises of this process:

Inheritable characteristics. Genetic variability. The variability of characteristics influences reproduction and survival.

The term Stabilizing Selection is unlike disruptive selection (diversifying selection) that tends to favor extreme traits when changes occur, stabilizing selection is defined as changes in population genetics in which extreme traits are not favored, rather, traits that are of intermediate variants are most favored and selected for.

In the scenario given, traits of producing fewer starlings or more are extreme traits that are not favored and have reduced fitness. Intermediate variants of producing moderate number of starlings that have high fitness demonstrates the type of selection that is referred by the term called stabilizing selection.

B. Large chunks of matter break off a planet that collides with a smaller body; these chunks gradually clump together to become a new planet. C. A rotating cloud of space dust and gases begins to flatten and condense, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets. D. A rotating cloud of space dust and gases begins to condense, forming a protoplanet; if the protoplanet is massive enough, its gravity will attract nearby matter until the protoplanet becomes large and round enough to be considered a planet.

Answers

Answer: B

Explanation:

Thats what the teacher told me

The scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."

What is the nebular hypothesis?

The nebular hypothesis is the most widely accepted scientific theory for the planetary systems, such that the solar system and, as per this theory, a cloud of gas and dust, called a nebula, collapse due to gravitational forces; the nebula contracts, and it rotates faster, flattening into a disk, which eventually cools and condenses, forming a protoplanetary disk.

Hence, the scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."
