Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction. Increasing the relative activity of MLCP, leading to a decrease in tension. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry. Lower levels of MLCK activity, leading to decreased contraction.
Answer:
1. Inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction.
2. Increasing the relative activity of MLCP, leading to a decrease in tension.
3. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry.
Explanation
In smooth muscle, cyclic AMP (cAMP) mediates relaxation because cAMP inhibits a specific kinase required for myosin light chain protein (MLCP) phosphorylation, thereby triggering contraction in the smooth muscles. It has been shown that cAMP inhibits 1,4,5-trisphosphate (IP3)-dependent calcium ions (Ca 2+) release by activation of the cGMP-dependent protein kinase (PKG). PKG proteins act to modulate Ca2+ oscillations by stimulating sarcoplasmic Ca2+-ATPase membrane proteins, increasing Ca2+ in the sarcoplasmic reticulum stores and Ca2+ efflux from the cells, and activate voltage-gated potassium (K) channels, thereby leading to membrane hyperpolarization and reducing Ca2+ entry through Ca2+ channels.
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.

what are the consequences of overdrawal of water?
Answer:
As the water table goes low, water may not be easily obtained leading to it scarcity. Overdrawal of water can also lead to sinking or lowering of the land surface that can make it prone to flooding. Streams and water bodies may also get disconnected due to over-withdrawal of water.

Which of the following is NOT a function attributed to Glia?
~They prevent toxic substances from reaching the brain.
~They process information going into the neuron
~They eliminate foreign substances inside neurons.
~They provide insulation for axons.
Answer:
~They process information going into the neuron
Explanation:
This is because Glia or neuroglia cells are cells found in the central nervous system that is brain and spinal cord and they did not transmit electrical impulses. Glia cells don't carry information because they don't carry electrical impulses. The cells include epipdymal cells,Schwann cells e.t.c.
They perform four major function and they include; They provide support and supply nutrients and oxygen to the cells,it prevent toxic or foreign substances from entering the neurons,they provide insulation for axons.

Explanation:
Genomic imprinting may involve a single gene, a part of a chromosome, or a whole chromosome. Indicate if the following statements are true or false regarding this phenomenon
1. Genomic imprinting is permanent in the somatic cells of a given individual. _____________
2. Genomic imprinting is permanent and affects future generations. ____________
3. Methylation is the chemical change underlying genomic imprinting. _____________
4. If a gene is imprinted, the offspring can express both the maternal and paternal allele. _________
Answer:
1. True.
2. False.
3. True.
4. False.
Explanation:
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.
1. True: Genomic imprinting is permanent in the somatic cells of a given individual.
2. False: Genomic imprinting is permanent and affects future generations. It does not affect future generations because generally it is expressed in a parent of origin specific form.
3. True: Methylation is the chemical change underlying genomic imprinting.
4. False: If a gene is imprinted, the offspring can express both the maternal and paternal allele. It is independent of Mendelian inheritance.

Answer:
The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.
Explanation:
Europeans was known to discovered Easter Island in 1722 and it's name was given by Captain Admiral Jacob Roggeveen.
The human population growth had a negative effect on the Easter Island.
The ecocide hypothesis is the one explanation to how the human population increased exponentially since its colonization and as such
Human populations did over increased the carrying capacity of the Island to support sustainable crops, and in consequence, the island was severely deforested.
The island's natural cycling of matter and energy also reduced or change and as such the people fought among themselves for scarce resources of the island. They had little food and were starving and they resorted to cannibalism.
The island was also plaque by blackbirding from 1862 to 1863.

Which pattern of inheritance does nose size follow?
complete dominance
codominance
incomplete dominance
sex-linked dominance
Answer:
incomplete dominance
Explanation:
This is because incomplete dorminance is a type of inheritance pattern in which a dorminant allele does not completely masked the effect of recessive allele. The recessive allele is expressed little and the dorminant. Example is the nose size. The allele for big nose and recessive allele for small nose are not completely dorminant.
