A gallon of water is a good choice - about 4.5 litres (depending on how many people of course).

Hope this helps!

It is required for each person to have at least a gallon of water for an emergency supply kit in a severe weather. This is because the water is not only going to be used for consuming purposes, but also for sanitation uses. This water should last for 3 days, approximately. 

I hope my answer satisfied you. :)

What is the diploid chromosome number for your karyotype
LekaFEV [45]

Answer:

For example, a haploid human nucleus (i.e. sperm or egg) normally has 23 chromosomes (n=23), and a diploid human nucleus has 23 pairs of chromosomes (2n=46). A karyotype is the complete set of chromosomes of an individual.

We think of termites as insects that eat wood. However, termites cannot digest the wood and rely on a variety of eukaryotic and
omeli [17]

Answer:

Obligate mutualism.

Explanation:

Obligate mutualism: It is defined as each organisms are obligated to each other, they rely on one another, means one species cannot survive without the other species. It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.

Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose. The termites do not have this ability to do this, without the help of protozoa. They are not able to use their energy from the food which is wood, cellulose comes from wood it chews.

So, termites are mutualistic related to protozoans and showing obligate mutualism.

Where exactly on the map does the size and concentration of the boxes appear to be the highest?
pav-90 [236]

The concentration and size of boxes the same at all locations is not the same size. The deaths due to cholera vary depending upon the location. The relative sizes represents that died at that certain spot.

Explanation:

The black boxes represent relative numbers of death due to cholera. Cholera is referred to as a disease of poverty because of the lack of social development in the areas in which it occurs. Crowded camps are fertile ground for a cholera outbreak. Other humanitarian crises including flooding and earthquakes, civil unrest or war that causes disruption of water and sanitation systems.

The following are required steps in the sliding filament theory of muscle contraction:
Olenka [21]

Answer:

In muscles contraction the correct order of the steps are: A (Nerve impulse reaches the muscle), B (Action potential travels down T-tubules), C (Calcium binds to troponin), D (Tropomyosin moves).

Explanation:

Skeletal muscle contractions are based on different physiological and biochemical phenomena that happen in every cell. These phenomena are due to stimulation produced by somatic motor neurons, which axons get in contact with muscle fibers through a neuromuscular synapse.  In rest, attraction strengths between myosin and actin filaments are inhibited by the tropomyosin. When an action potential is originated in the central nervous system, it travels to the somatic motor neuron membrane: the muscle fiber, and activates the calcium channels releasing it in the neuron. Calcium makes vesicles to fuse with the membrane and release the neurotransmitter named acetylcholine (Ach) into the synaptic space in the juncture. Then, Ach binds to its receptors on the skeletal muscle fiber. This causes the ion channels to open, and positively charged sodium ions cross the membrane to get into the muscle fiber (sarcoplasm) and potassium get out. The difference in charges caused by the migration of sodium and potassium makes the muscle fiber membrane to become more positively charged (depolarized). The action potential caused by this depolarization enters the t-tubules depolarizing the inner portion of the muscle fiber. This activates calcium channels in the T tubules membrane, that make the calcium be released into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to the troponin C, the troponin T alters the tropomyosin by moving it and then unblocks the binding sites. Myosin binds to the uncovered actin-binding sites, and while doing it ATP is transformed into ADP and inorganic phosphate. Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.
