Answer:
1. Acetylcholine:
- Muscarinic
- Nicotinic
- Associated with mushroom poison
- Only receptor found in parasympathetic synapses
- Associated with tobacco
2. Norepinephrine:
- alpha-Adrenergic
- beta-Adrenergic
- Utilizes calcium ions as a second messenger
Explanation:
Acetylcholine (ACh) is a neurotransmitter that acts in both the central and peripheral nervous systems. Cholinergic receptors are receptors that bind to ACh. Muscarinic receptors are G protein-coupled receptors involved in the parasympathetic nervous system, which play roles in a variety of physiological responses (e.g., ACh binds to muscarinic receptors in the pathophysiology of asthma, leading to an increased mucus secretion). Nicotinic receptors bind to nicotine, while muscarinic receptors bind to muscarin (muscarine is a well-known neurotoxic alkaloid found in certain mushrooms). Nicotine receptors are also called cholinergic receptors since they also respond to ACh. On the other hand, norepinephrine (NE) binds to alpha-adrenergic and beta-adrenergic receptors in different tissues. Both alpha-adrenergic and beta-adrenergic receptors are G-protein coupled receptors. Alpha-adrenergic receptors are involved in the regulation of blood pressure and generating a sympathetic 'fight and flight response'; whereas beta-adrenergic receptors modulate sympathetic responses in the cardiovascular, metabolic, and central nervous systems (NE activates the beta1-receptor). NE can induce Ca2+ release, which is a second messenger that controls a wide variety of cellular processes.

Why do scientists study seismographs?
To analyse mineral content from earth's crust
Answer:
To determine the location of an epicenter
Explanation:
A seismogram is a graph output by a seismograph ; a record of the shaking and vibration of the ground. By studying seismograms, scientists learn a lot about Earth's internal structure, like how fast the waves are moving and what type of material the waves are passing through.
Ahmad is using technic cross-pollination for his mango plants in his orchard. He said combines genetic materials from two parent plants of the same species will has many advantages. Justify the statement.
Answer:
Due to some extra features.
Explanation:
Genetic materials from two parent plants of the same species has many advantages because the offspring produced from two parents having characteristics from both parents which make it different from their parents. Due to this non-identical nature of offspring which has many new features which enables the plant to resist many diseases, faster growth and high productivity so that's why sexual reproduction has many benefits to organism.

Which group of bacteria reduces nitrate to nitrogen gas in the nitrogen cycle? Nitrogen fixing bacteria C. denitrifying bacteria Ammonium ion forming bacteria D. photosynthetic bacteria
Answer:
C. denitrifying bacteria
Explanation:
Nitrogen cycle consists of series of processes that add and remove nitrogen from the soil and atmosphere. There are several ways in which nitrogen can be added to the atmosphere including nitrification, ammonification, lightning etc.
Certain bacteria are responsible for the conversion of nitrogen from one compound form to another. In a process called DENITRIFICATION, nitrate (NO3-), which is the usable form of nitrogen by plants, is converted back to atmospheric nitrogen (N2) with the help of a bacteria called DENITRIFYING BACTERIA e.g Pseudomonas etc.
Using sophisticated molecular cloning techniques, you have isolated the genes for two serotonin transporters, called TransA and TransB, which are expressed in these neuronal cells. A preliminary immunofluores- cence localization of fixed and permeabilized cells found very bright staining of TransA at the nerve cell plasma membrane and little staining elsewhere. TransB, in contrast, stained only very faintly at the nerve cell plasma membrane, but there was intense staining within the cytosol.
Required:
In which subcellular membrane or organelle would you expect most of the TransB to be found? Explain your answer.
Answer:
Vesicles
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.
Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.
The neurotransmitter concentration in the vesicle interior is related to the storage system and the transport system. There are specialized transporter proteins in the vesicle membrane that are involved with the introduction of the molecule to the organelle.
In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.

In most unsaturated fatty acids found in animal fats, vegetable oils, and biological membranes, the cis isomer predominates. true false
Answer:
The correct answer is - true.
Explanation:
Most unsaturated fats are oils and normally are biological membranes or plant-based such as vegetables. These fats mostly have cis isomer in them. Unsaturated fats help to lower blood cholesterol levels.
However, few oils show saturated fats but these are few in number, the majority are made up of unsaturated fats that have double bonds.
Should we clone animals that are going or have gone extinct (in other words bring them back
either from the brink of extinction or from extinction)? Explain your answer.
Answer:
I think we should but people are preventing this though
Explanation:
I think we should because it might benefit the world and let scientists to discover this animal. But then I don't think so because animals that are/were extinct could perhaps be from climate change. Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)

What is the biggest problem of over use of pesticides
Answer:
There have been many issues that have been seen to arise due to the over use of pesticide including:
Explanation:
Overuse has been linked to cancer, Alzheimer's Disease, ADHD, and even birth defects. Along with being reporting to have the potential to harm the nervous system, the reproductive system, and the endocrine system.
Answer:
Pollution.
People applying them are exposed to toxic chemicals. People who live nearby can be exposed too with wind blowing them around.
With rain or just watering of plants, the pesticides 'run off' and end up in water supplies, rivers, lakes, and eventually oceans.
Also, organisms can mutate and make pesticides useless.

Genes:
A. in plants exist only in some individuals
B. they determine the structural and functional characteristics of each individual
C. they determine only the functional characteristics of each individual
D. they determine only the characteristics structural of each individual
E. do not exist in prokaryotes
Answer:
B. They determine the structural and functional characteristics of each individual
Explanation:
Genes are present in all plants and in all prokaryotes, so answer choices A and E are incorrect. Genes are present in all living things.
Genes do determine the structural characteristics of each individual, but they also determine the functional characteristics.
Structure, which is controlled by genes, directly affects function. For example, a gene could code for a specific protein's structure, which will in turn give it a specific function.
So, the correct answer is B.
