Answer:
Recessive
Explanation:
When there is a skipped generation, the trait must be RECESSIVE. For dominant trait, having 1 dominant allele will give you affected phenotype. It can never give a skipped generation.

In the oceans on either side of the Isthmus of Panama are 30 species of snapping shrimp, 15 species on the Pacific side and 15 different species ch the Atlantic sid. See different water depths. Morphological and genetic data show that Atlantic and Pacific species that live at similar depths are sister species. Geological evidence indicates that the Isthmus of Panama started rising about 10 million years ago and the oceans were completely separated by the stimus about 3 million years ago. If the geological evidence has been misinterpreted and the isthmus had formed very rapidly in less than 1,000 years), which of the following predictions is most likely?
A. greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabt stalow water
B. greater percentage of difference in DNA sequences between sister species that inhabit shallow water than between sister species that inhabit deep water
C. similar percentages of difference in DNA sequences between all pairs of sister species
D. greater percentage of difference in DNA sequences between Atlantic species than between Pacific species
Answer:
The answer is "Choice A".
Explanation:
The Panama isthmus is indeed a patch of land which separates its sea from its Atlantic ocean to The pacific in two halves. The Panama Isthmus allows spreading the seafood applicable state, although due to geographical barrier, the very same turtle species were isolated. Its deep squirrels of liquid are diverged quite early as being against shallow water shrimps which are characterized by the rising of the Jamaica isthmus, first off the island can be crossed until it was closed through shallow water prawns and shallow-water animals. If Panama's black sea was established less than 1000 years, it has a greater effect on deepwater shrimp and very low water lobsters. Consequently, in water depth prawns, a disparity in hereditary degree (DNA) is higher than in shallow species. The deep waters have been affected earlier so the variation in DNA sequences throughout all sister species will not be the same.
Using compaction and cementation explain why sedimentary rocks are not just a loose pile of sand and rocks.
Compaction and Cementation They are compacted, reducing the available pore space and expelling much of the pore-water. Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.
Through compaction and cementation, minerals form a crusts on the sedimentary rocks which are no longer just a loose pile of sand and rocks.
What are sedimentary rocks?Sedimentary rocks are formed from the pre-existing rocks or pieces of or fossils of living organisms. They form from the deposits which accumulate on the surface of Earth. Sedimentary rocks often have distinctive layering or bedding over Earth.
Dissolved minerals present in the ground water precipitates from the water surface present in the pore spaces forming mineral crusts on the sedimentary grains, which gradually undergo cementing the sediments, which thus lead to formation of a rock.

The role of the institutional animal care and use committee (IACUC) of a research institution is to provide research animals with clean and healthy conditions in the laboratory. mediate the acquisition of animals by the institution's researchers. review all proposals for animal research to be sure the procedures to be used are appropriate and humane. review animal research proposals only to ensure that the proposed experiments are scientifically valid.
Answer:
review all proposals for animal research to be sure the procedures to be used are appropriate and humane.
Explanation:
The Institutional Animal Care and Use Committee (IACUC) is a federal committee responsible for approving and/or prohibiting the use of animal (nonhuman vertebrate) subjects for research, testing and teaching purposes, as well as the inspection of animal facilities. IACUC evaluates the institution's animal programs and procedures as described by the Office of Laboratory Animal Welfare (OLAW). This committee has the task to verify animal's well-being by minimizing pain and distress (for example, by ensuring the use of non-invasive methods when possible). Researchers/educators that use animals for research/teaching purposes must previously submit a written request defined by the IACUC's guidelines.

Write the correct type of mutation that occurred in creating the mRNA strand for each of the following
examples. Original DNA: ATCCGCTTACG
a. UUGGCGAAUCG: __________________
b. UATGGCGAAUCG: _________________
c. UGGCGAAUCG:__________________
Answer:
a. the second nucleotide is wrong. It is a U but should be an A. No other nucleotides were effected by this, only the one was effected. This is a Point (Substitution) Mutation.
b. the third nucleotide is wrong. It is a T that was inserted. As you can see, the rest of the nucleotides are right, but since the T was added, it will mess up how the rest of the sequence is read. It will be read UAT GGC GAA... instead of UAG GCG AAU... see how it messed it up? This is an Insertion (Addition) Mutation.
c. the second nucleotide was deleted. This is called a Deletion Mutation. It will mess up the rest of the sequence, similar to how the example above did.

Which activities cause environmental pollution in your locality.Write how you can help to avoid them
Answer:
Activities cause environmental pollution is AIR POLLUTION
Can avoid by:
•Conserve energy at home at work,everywhere.
•Use public transportation or walk whenever possible.
•Keep car, boat and other engines properly tuned.
•Mulch or compost leaves and yard waste.
•Consider using gas logs instead of wood.
The activities that cause environmental pollution in my locality are the excessive usage of vehicles that emits a huge amount of carbon, excessive utilization of polythenes, and no proper method of waste treatment.
What is Environmental pollution?Environmental pollution may be defined as any sort of unwanted contamination or impurities present in the atmosphere that is harmful and toxic to the health of each and every living organism. It is one of the most threatening problems for the whole world that affects the overall diversity of living entities and ecosystems.
You can avoid all the activities listed above by following mechanisms:
Increase the use of electric vehicles rather than petrol or diesel vehicles. Enhance the utilization of poly bags that are easily decomposable and cause less harm to the land and soil. Installations of some authorized and trusted mechanisms for waste treatment.Therefore, it is well described above.

Find the edge length of the cube. (The density of copper is 8.96 g/cm3, and the volume of a cube is equal to the edge length cubed.)
Express your answer with the appropriate units.
Answer:
[tex]x = 2.13\ cm[/tex]
Explanation:
See comment for complete question
Given
[tex]Mass = 87.2g[/tex]
[tex]Density = 8.96gcm^{-3[/tex]
Required
Calculate the edge length of the cube
First, we need to calculate the volume of the cube using:
[tex]Density = \frac{Mass}{Volume}[/tex]
Make Volume the subject:
[tex]Volume= \frac{Mass}{Density }[/tex]
Substitute values for Mass and Density
[tex]Volume= \frac{87.2g}{8.96gcm^{-3}}[/tex]
[tex]Volume= \frac{87.2cm^3}{8.96}[/tex]
[tex]Volume= 9.73cm^3[/tex]
Represent the edge length with x.
So:
[tex]Volume = x^3[/tex]
Substitute x^3 for Volume in [tex]Volume= 9.73cm^3[/tex]
[tex]x^3 = 9.73cm^3[/tex]
Take cube root of both sides
[tex]x = \sqrt[3]{9.73cm^3}[/tex]
[tex]x = 2.13\ cm[/tex] --- approximated
Hence, the edge length is 2.13cm

The number of neurotransmitter molecules located within a specific synaptic gap would most clearly be
reduced by
Answer:
The correct answer is - reuptake.
Explanation:
The process that reabsorbs the neurotransmitters known as reuptake which reduced the number of neurotransmitter molecules. Neurotransmitter transporter found on the outer membrane of the plasma membrane assists the process of reuptake by reabsorbing the neurotransmitter molecules from the specific synaptic gap. Neurotransmitters recycle by this process in order to reuse again after a time for the particular signal to last.
Thus, the correct answer is - reuptake.
