Answers

Answer:

D. By the making of glucose through photosynthesis

Explanation:

Photosynthesis is a chemical reaction that results in glucose. One of the reactants is CO2. So, the plants take in CO2, water, and sunlight. This produces oxygen and glucose. This is part of the carbon cycle and is the way that CO2 becomes usable for consumers.

Does hot water tend to rise or sink? Explain.

Answers

Answer:

When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.

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.

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 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].

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.

One of the most common chromosomal disorders is Down syndrome. Down syndrome happens when abnormal cell division results in extra genetic material from chromosome 21, too few chromosomes, or part of a chromosome may be missing. The difficulties of Down syndrome include hearing and vision weakness, weak auditory memory, fine motor skill impairment, short attention span with distractibility. Having Down syndrome can increase the risk of developing Alzheimer's disease. Having down syndrome can be associated with other health conditions such as ear infections, dental problems, endocrine problems, and seizures.

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.
