The tundra is characterized by extremely low temperatures as well as little precipitation, a rocky landscape, and permafrost. Because of these physical features, what type of producers would we expect to find in the tundra?

Given tundra's unique environment, we can expect specific type of plants thriving. The dominant types are lichens, which are considered as the primary producers. Next are the mosses, which doesn't have real leaves and roots. The types of plants living in tundra are usually plants with specialized system because of a unique environment. Flowering plants may live but only limited to particular species.

1. How do your skeleton and muscular system work together, 2. What type of muscle tissue would you find in the heart? blood vessels? toes?

The answer to your first question involves a connection between your actions and your brain. Your bones and muscles work together through a series of impulses and signals communicated between the brain and skeletal muscles. In order to move, the nervous system then sends signals a skeletal muscle to contract. When the muscle contracts, this movement causes the attached bone to follow.

And as for your second question, 
The muscle tissue in your heart is cardiac, the muscle tissue in your blood vessels is smooth, and the muscle tissue in your toes is skeletal. 

I hope this helps you, have a nice day!

Sort the phrases into the appropriate bins depending on which type of postsynaptic potential they describe. If a phrase describes both types of potentials, drag it to the "both" bin.

Excitatory postsynaptic possibilities (EPSPs) are excitatory in light of the fact that they make the postsynaptic neuron more prone to produce an activity potential by depolarizing the layer (making the film potential less negative) and conveying the layer potential more like an edge. This is regularly expert by opening ligand-gated Na+ diverts in the postsynaptic layer, which enables Na+ particles to enter the cell. 
Interestingly, inhibitory postsynaptic possibilities (IPSPs) make it more troublesome for the postsynaptic neuron to create an activity potential by hyperpolarizing the layer (making the film potential more negative) and moving the film potential more distant from the limit. This is frequently proficient by opening ligand-gated K+ directs in the postsynaptic layer, which enables K+ particles to leave the cell. 
Despite whether they are excitatory or inhibitory, all postsynaptic possibilities are reviewed, implying that their sizes are variable. (Activity possibilities, then again, are all-or-none occasions.) And on the grounds that a postsynaptic potential is not proliferated like an activity potential, its greatness diminishes with separation from the neurotransmitter along the cell body.

A. decantation and screening B. distillation and screening C. decantation and centrifugation D. distillation and filtration

Based on the given instruction above, I can say that the separation methods that are being used in the recipe are DECANTATION AND SCREENING. The answer would be option A. When we say decantation, this is a process of separating liquids in order to remove the layer of liquid that has precipitates in order to produce a cleaner product. Hope this helps.

In a paragraph address these following questions: • How does an underwater earthquake cause a tsunami? • Why do some earthquakes cause more damage than others? the paragraph needs to also include the following things: • discuss how the different types of waves are formed and describe how the waves travel • explain how scientists use waves to track and analyze earthquakes • cover recent events involving earthquakes and/or tsunamis that illustrate the points made in your explanation

What is an Earthquake

Earthquakes are vibrations in the earth's crust They occur along all plate boundaries but are more destructive usually at destructive plate boundaries

How are they measured

The magnitude or size of an earthquake can be measured by an instrument called a seisometer and are shown on a seismograph. The earthquakes are measured on the Richter scale from a value of 1 to 10. Each level of magnitude is 10 times more powerful than the previous. Therefore a level 7 is 100 time more powerful than a level 5.

Why do some earthquakes cause more damage than others?

Some earthquakes take place in rural areas where few people live and little is damaged

If they occur near large urban areas with many people, transport services, large buildings and services such as gas and electricity - there can be a great amount of deaths and damage

In Poor countries - LEDC's they have poorly built buildings, few emergency facilities, and the equipment to help rescue people - a good term to use is that they have a poor infrastructure.

In rich countries - MEDC's such as the USA they prepare for an earthquake with drills and have a great deal of trained emergency personnel and equipment to go to help the injured. They also try to build to withstand earthquake damage - ie The Transamerica building

The time of day can be important - If the earthquake hits when it is the rush hour or when there is a large number of people located in a certain area - this can cause a great loss of life

Obviously if they occur near to coasts then Tsunamis can cause a great deal of damage and deaths such as the 2004 Boxing Day Tsunami

Plant hormones are signalling molecules, produced b plants that regulate growth, development and other cellular processes of plants. There are five types of plant hormones, which include abscisic acid, auxins, cytokinins, ethylene, and gibberallins.

Given chart represents relationship between different plant hormones and their responses or functions. Auxin promotes plant growth, plays role in tropism, abscisic acid plays role in seed and bud dormancy, cytokinin promotes cell division, ethylene controls plant growth and stimulates flowering, and gibberallins cause stem elongation.

Thus, the correct answer is option (B).

A small child managed to eat a bit of dirt while playing outside. Which of the following would prevent the child from getting sick from the bacteria ingested? A If there were not a pathogenic bacteria in the dirt B If the child had previously taken antibiotics for that type of bacteria C If the child already had the antibodies to fight the bacteria D If the child’s cells had complementary receptor molecules that bind to the bacteria


C If the child already had the antibodies to fight the bacteria


There are a lot of bacteria that we have already storage antibodies for, our immune system is like a database of antibodies that learns with every disease we get, some of them won´t even manifest, because our immune system is strong and produces enough antibodies to counterattack the germs. So from the options given, the most reasonable and possible is that the kid already had the antibodies to fight that bacteria.
