Answer:
1. It should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. There are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but I can't think of an example where the fears didn't turn out to be baseless.
2. Yes. First, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. The pros involve better medical treatment. The cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. Looking at DNA markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. And OK, actually I suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency.

3. If muscle contraction were an athletic game, calcium would be the most valuable player. Describe,
using some depth, the roles calcium is serving both inside the muscle fiber and outside at the NMJ.
Answer:
Explanation:
At the NMJ, calcium is responsible for "unlocking" the ligand gated channels, allowing AcH to be released into the synaptic cleft. When AcH binds and the AP moves down the sarcolemma and into the t-tubule, calcium is then released from the sarcoplasmic reticulum into the sarcoplasm. It then binds to the calcium subunit of troponin, causing a confirmational change in tropomyosin, exposing the active sites on actin. This allows the myosin heads to bind, causing muscle contraction.

Answer:
Explanation:

What might happen to the Earth if human increase the amount of greenhouse gasses?
Explain your answer.''
Answer:
Global warming will occur
Explanation:
Greenhouse gases are special gaseous compounds that have this ability to trap HEAT due to their structural composition. They include; carbon dioxide (CO2), chlorofluorocarbons (CFC), methane (CH4) etc.
Anthropogenic activities such as burning of fossil fuels etc. release these gases into the atmosphere where they cause harm to the Earth. Greenhouse gases contribute immensely to the GLOBAL WARMING EFFECT, which is the increase in the temperature of the Earth surface. Therefore, if humans increase the amount of greenhouse gases in the atmosphere via their actions, there will be a GLOBAL WARMING occurrence.

The function of the liver in humans is to maintain the [glucose] circulating in the blood stream at reasonably constant levels. This is so organs like the brain that use primarily glucose as their carbon source to produce energy via ATP have a steady supply of glucose. It also ensures that the levels of glucose in the blood stream do not get too high. Using the plots from problem 6, discuss why it makes sense that glucokinase in liver would behave differently than the hexokinase in other cells.
Answer:
Due to difference in function.
Explanation:
Glucokinase in liver behave differently than the hexokinase in other cells because glucokinase performs different function in the body. Glucokinase is an enzyme that is responsible for sensing the glucose level in the blood and also plays a key role in the storing of glucose as glycogen while on the other hand, this storing ability is absent in hexokinase so that's why the glucokinase in liver behave differently than the hexokinase in other cells.

Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH is his real belts appear in the table below
Answer:
B. Enzymes have particular pH's at which they function best
Explanation:
The table in this question describes the reaction rate of two enzymes (enzyme 1 and 2) measured in mmol/min. According to the question, Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH.
At pH 7-9, the reaction rate of enzyme 1 was more than that of enzyme 2 while from pH 9.5-11, the reverse was the case. This portrays that the reactivity of an enzyme is in response to the pH they are placed in. In other words, different enzymes have particular pH's at which they function best.
Plants can reproduce both sexually and asexually. What are some examples of sexual reproduction in plants? Select ALL that apply. Responses
Sexual reproduction in plants involves the fusion of male and female gametes to produce offspring with genetic diversity.
Mechanisms that facilitate sexual reproduction in plants are examples:
1)Pollination and Fertilization: Many plants rely on pollinators, such as bees, butterflies, or birds, to transfer pollen from the male reproductive structures (anthers) to the female reproductive structures (stigma) of flowers.
This process enables the fusion of sperm cells within the pollen with egg cells in the ovules, leading to fertilization.
Examples include flowering plants like roses, sunflowers, and apple trees.
2)Seed Production: After fertilization, the ovule develops into a seed. Seeds contain an embryo, formed by the fertilized egg, enclosed within a protective seed coat.
The mature seeds can disperse and germinate to give rise to new plants.
Various plant groups, including angiosperms (flowering plants) and gymnosperms (conifers and cycads), reproduce sexually through seed production.
3)Alternation of Generations: In plants with a complex life cycle, such as ferns, mosses, and liverworts, sexual reproduction involves an alternation between two distinct generations: the gametophyte and the sporophyte.
The gametophyte generation produces gametes (sperm and eggs) through specialized structures, while the fusion of gametes gives rise to the sporophyte generation, which produces spores.
4)Self-fertilization: Some plants have the ability to self-fertilize, where the pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant.
This allows for sexual reproduction without the need for external pollinators. Self-fertilization can be seen in plants like tomatoes, peas, and certain grass species.

A red animal (AA dominant) mates with a yellow animal (aa recessive). What would be the genotype and phenotype of a heterozygous offspring? (Assuming
complete dominance)
a.phenotype (yellow): genotype Aa
b.phenotype (red); genotype AA
c.phenotype (yellow); genotype aa
d.phenotype (red): genotype Aa
Answer:
d.phenotype red: genotype Aa
Explanation:
a red animal that is a Donna Mae a would still have dominance over the yellow animal it recessive so if you put it in the chart form AA would be on top and the lowercase a a would be on the left side so it would be phenotype red genotype capital a lowercase a .
In codominance, the genotype of the cross will be Aa and the phenotype will be yellow. Therefore, option "A" is correct.
What is codominance?Codominance is a genetics-related term. The term means a type of inheritance, where two versions (alleles) of the same gene are expressed separately. This lead to the yield of different traits in the offspring. Examples are when in animals such as speckled chickens, having alleles for both types of feathers, black and white.
Roan cattle is also an example of co-dominance, which expresses alleles for both red hair and white hair. Codominance is also present in plants. Examples are rhododendrons which have a simultaneous expression of red and white genes for flower color display flowers with both red and white petals.

What type of conservation will result in the greatest reduction in the burning of fossil fuels?
Answer:
Conservation of air.
Explanation:
Conservation of air will result due to greatest decrease in the burning of fossil fuels because fossil fuels greatly damage the air. The burning of fossil fuels produces carbondioxide gas in large amount that can be released in the atmosphere. This increase in carbondioxide gas in the air causes pollution that leads to global warming as well as health problems in humans. So we can conclude that decrease the use of fossil fuel leads to conservation of air.
