Which statement best explains the difference between water temperature at
the poles and water temperature at the equator?
O A. The water is denser and saltier near the equator, so it holds more
heat.
B. The sun's rays strike the water at an angle at the poles.
C. Deep sea vents pump steam into the conveyor belt near the
equator.
D. Due to Earth's rotation, gyres near the poles flow clockwise.
Answer:
B. The sun's rays strike the water at an angle at the poles.
Answer:
b
Explanation:
At high latitudes, ocean waters receive less sunlight – the poles receive only 40 percent of the heat that the equator does. These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold -2°C (28°F) near the poles

Refer to Animation: Cell Signaling: Adrenaline Signaling in the Heart Muscle. Adrenaline stimulates an increase in heart rate by binding to: G proteins on the cytosolic face of the plasma membrane. adenylyl cyclase. regulatory regions in genes that code for muscle cell proteins. G protein-coupled receptors on the surface of heart muscle cells. nuclear transport proteins that allow adrenaline to be taken into the nucleus to act as a transcription factor.
Answer:
The correct answer is ''G-protein coupled receptors on the surface of cardiac muscle cells.''
Explanation:
Adrenaline is a catecholamine whose pharmacological effects occur at alpha and beta adrenergic receptors. The mechanism of action of all beta adrenergic receptors is the activation of a G protein that activates adenylyl cyclase and increases cyclic AMP production. Adrenaline by b-adrenergic stimulus increases the contractile force of the myocardium (positive inotropic action) and increases the frequency in which the myocardium contracts (positive chronotropic action), consequently there is an increase in cardiac work, with a greater demand for oxygen due to the myocardium to be able to contract. Therefore, the blood flow to the heart is indirectly increased, bringing with it a greater supply of oxygen.
how does secondary succession differ from primary succession? it begins on bare rock or land, it begins where no plants have grown, lichens and mosses form soil first, soil nutrients are already in place
in georgia or in the crib
Answer:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

Ecotourism can provide an incentive for local people to preserve the environment in order to attract more visitors, but sometimes development is done with little planning for long-term environmental impacts. On a small island in the Caribbean, a local group is considering opening a resort for ecotourism. If they wish to build a sustainable and ecofriendly business, what should be the next steps in their plan?
A. Investigate the ecological impacts and gather evidence on which to base their decisions
B. Hire an agent to locate a suitable property and start developing infrastructure
C. Market the development to investors and explain ecotourism to them to raise money for the resort
D. Determine what types of activities the resort will offer and hire staff
Answer: The next steps in their plan should be to (Investigate the ecological impacts and gather evidence on which to base their decisions). The correct option is A.
Explanation:
ECOTOURISM is defined as the visitation of individuals (tourist) to natural areas that conserve the environment and sustains the well-being of the local people. It has to do with the interaction of the biotic components of the natural environment by tourists. This has the advantage of providing an incentive for the local inhabitants but can cause a long term negative environmental impact of not properly planned.
Conservation of these natural resources improves the quality of lives. It enables the inhabitants to live in a clean and healthy environment (eco-friendly). To set up a tourism center, certain rules and regulations needs to be met in order to avoid endangering both the biotic and abiotic components of the ecosystem. Therefore these local groups should investigate the ecological impacts and gather evidence on which to base their decisions. This would help conclude if a particular selected environment is conducive.

In a haplodiploid mating system, how can the coefficient of relatedness between two sisters be 0.75 (75%)? Females are haploid, and they pass on 100% of their genes, whereas males are diploid and pass on 50% of their genes, meaning that the coefficient of relatedness is 0.75. Females can reproduce asexually, meaning they produce clones, and those clones share on average 75% of the genes of their sisters. If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes. Male and female bees are both diploid. The males contribute 100% of their genes to their offspring, and females contribute 50%. Therefore, each female offspring shares 75% of her genes with her sister siblings on average.
Answer:
If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes
Explanation:
Haplodiploidy is a type of sex-determination system where males are haploid (i.e., they contain only a set of chromosomes 'n') and develop from unfertilized eggs, whereas females are diploid (i.e., they contain two complete sets of chromosomes '2n') and develop from fertilized eggs. The bees show this haplodiploid system of sex determination, which is quite common to many hymenopterans. In bees, workers and queens are diploid (2n) females and contain 32 chromosomes, a set of 16 chromosomes is contributed by the queen's egg, and another set of 16 chromosomes is contributed by the drone sperm (16 + 16 = 32 chromosomes). On the other hand, drones are haploid (n) males and contain only one set of 16 chromosomes, which is exclusively contributed by the queen's egg.

Name at least three neuromitters and state the roles of these neuronmitters in human body ? Except acetylcholine, (GABA)and domanine. Please help as soon .
Answer:
Explanation:
The chemical messengers present in the body are known as neurotransmitters. These are the chemicals that the nervous system uses to send and receive information between neurons and muscles. A neurotransmitter can have one of three effects on a neuron:
Excitatory effect, Inhibitory effect, and/or Modulatory effect.
The list of neurotransmitters and their roles are as follows:
Glutamate: This is present in amino acid compounds which are located in the synapses. It functions as an excitatory neurotransmitter, causing neurons to discharge instructions when stimulated in the central nervous system.
Adrenaline: It helps to respond to body's psychological stress and protection mechanism. They are positioned above the kidney and are created by the adrenal glands. They operate throughout the central nervous system and swiftly increase your heart rate and provide oxygen to your muscles.
Serotonin: Serotonin is a crucial brain neurotransmitter that also has a role in the small intestine. In your digestive tract, serotonin increases feelings of contentment after eating and controls your appetite. When you eat anything that doesn't agree with your stomach, serotonin assists your body in getting rid of it.
