The pink parts of the graph represent the pH range where some common freshwater organisms survive. If the pH of a lake were to s

tart at 3 and become more basic, at what pH would these freshwater organisms begin to die out?

Most organisms can tolerate a very narrow pH range close to neutral, i.e., around pH 7. It is likely that there would not be much life in the lake at pH 3. Once the pH increases to above 5.5 to 6, it is more likely that life would begin to survive. Once the pH rises to above around 9, the solution is starting to become basic, and once again, few organisms will survive.

4.0 As the pH increases, the first type of fish, catfish, would begin to die off at a pH of 4.0. By the time the pH increased to 5.5, all organisms would be removed.

Large bodies of water take ____________ time to change temperature than land.
zaharov [31]

Answer:

Large bodies of water take more time to change temperature than land.

Explanation:

Large bodies of water take more time to change temperature than land because more energy is required by water to in order to make the water evaporate, therefore, water takes more time to change its temperature as compared to the land. Water also has a particular temperature which takes more time in order to be changes. Land is not transparent, therefore, heat or cold has no need to be get penetrated in it, whereas, water is a transparent medium where heat and cold is required to get absorbed till its deep end, so it takes more time for water to change its temperature as compared to land.

A--What do you get if you add the number of maternal chromosomes in a somatic cell to the number of autosomes in a sex cell, the
madam [21]

Answer:

44

Explanation:

A somatic cell is diploid - it has 46 chromosomes. Half of these are from the mother, so there are 23 maternal chromosomes

A sex cell (gamete) is haploid - it has 23 chromosomes. There are (usually) two sex chromosomes in a diploid genome, either XX or XY, so there is one 1 in a haploid cell, giving a total of 22 autosomes

Barr bodies are inactive X chromosomes in a female somatic cell. This occurs to control dosage compensation (otherwise all the genes on the X in females would be expressed twice as much as they are in males). In a healthy female, there is normally one Barr body

A person with Kleinfelter's syndrome has two X chromosomes and one Y (XXY). They are biologically male, but have two X chromosomes. Therefore, one of these becomes a Barr body, as in females.

23 + 22 - 1 = 44

Two insect groups vary genetically by two genes. When put together,they were able to reproduce and produce offspring that could
nikitadnepr [17]
<h3>Your answer is D.</h3>

The insects are the same species.

<h3>Explanation:</h3>

A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.

Methodology of pteridophytes​
jeka57 [31]

Answer:

Plants from this group have well-developed roots, stem and leaves and separate tissues for conduction of food and water .But ,they do not bear flowers and fruits.They reproduce with the help of spores formed along the bach or posterior surface of their leaves.Examples : Nephrolepis,Marsilea,Adiantum, Equisetum, Lycopodium, Selaginella,etc.

These plans reproduce asexually by spore-formation and sexuall by zygote formation.They have a well-developed conducting system.

Explanation:

hope this helps!
