Why isnt there a solar eclipse during every new moon?

Answers

Answer:

Eclipses do not happen at every new moon, of course. This is because the moon's orbit is tilted just over 5 degrees relative to Earth's orbit around the sun. For this reason, the moon's shadow usually passes either above or below Earth, so a solar eclipse doesn't occur.

how can different amino acids affect secondary structure

Answers

Answer:

Exposure to positively charged amino acids (arginine and lysine) is found to clearly stabilize the secondary structure. Kinetically, each amino acid promotes folding by generating a large increase in the folding rate with little change in the unfolding rate.

how do I write the equation P^2 = kA^3, so that I'm solving for the variable K?

Answers

Answer:

k = (P^2)/(A^3)

Explanation:

Step 1: Flip the equation.

[tex]kA^3 = P^2[/tex]

Step 2: Divide both sides by A^3.

[tex]\frac{kA^3}{A^3} = \frac{P^2}{A^3}[/tex] [tex]k = \frac{P^2}{A^3}[/tex]

Therefore, the answer is [tex]k = \frac{P^2}{A^3}[/tex].

O Monera, Bacteria, and Protista
O Fungi, Monera, and Protista
O Bacteria, Insecta, and Protista

Answers

Answer:

C

Explanation:

Fungi, Monera, and Protista are the three kingdoms he neglected to mention.

What Linnaeus classification?The Linnaean system is based on similarities in apparent physical qualities. This system is a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name. The domain, which was just added and is a larger taxon, is smaller than the kingdom. Seven levels make up Linnaeus' hierarchical classification scheme. They are kingdom, phylum, class, order, family, genus, and species, in order of largest to smallest. Linnaeus created a hierarchy for nature in Systema Naturae. He suggested that the entirety of nature may be divided into three big categories known as kingdoms. Animals, plants, and minerals made up these three kingdoms. He categorizes each of these kingdoms.

Explanation:

what are the functions of the kidney

Answers

Basic Functions
The kidneys are essential for homeostasis (maintaining a constant internal environment) of the body's extracellular fluids. Their basic functions include:
1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.

2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.

3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.

4. Regulation of pH. The kidneys prevent blood plasma from becoming too acidic or basic by regulating ions.

5. Excretion of wastes and toxins. The kidneys filter out a variety of water-soluble waste products and environmental toxins into the urine for excretion.

6. Production of hormones. The kidneys produce erthryopoietin, which stimulates red blood cell synthesis, and renin, which helps control salt and water balance and blood pressure. They are also involved in regulating plasma calcium and glucose levels.

Explanation:

When you heat up water, the water molecules start moving around faster and faster. ... So hot water is less dense than cold water. When you put the two together with the hot water on the bottom, the hot water rises to the top.
