Answer: Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum.

Explanation: Photons reflected by pigments in leaves are used by leaves to carry out photosynthesis is not true as the photons are absorbed as a source of energy by the pigments to carry out the process of photosynthesis.

Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum is true as only visible light is visible to human beings.

Photons are units of light that travel from the sun to leaves in the same way that particles travel through space is not true as photons travel from the sun to leaves by radiation in the form of electromagnetic waves and do not require any medium but particles require medium to travel.

The wavelengths that make up the electromagnetic spectrum each have the same amount of energy is not true as the electromagnetic radiations have different wavelengths and thus have different energies.

$E=\frac{hc}{\lambda}$

The ultimate source of energy for starting the food chain is: 1glucose 2starch 3ATP 4in cells solar

balu736 [363]

The ultimate souce of energy for the food chain is solar energy from the sun. It allows plants to convert the solar energy to chemical energy for growth. The growing plants in turn allow heterotropic animals to consume them to obtain energy of their own.

What soil composition would be best for availability of nutrients, water, and root development? A. equal amounts of sand, clay,

Travka [436]

Soil composition would be best for availability of nutrients, water, and root development higher proportion of humus; lower amounts of clay and sand

Compared to the lower soil layers, the topsoil or surface soil often includes more organic matter and air but less clay. The topsoil typically has the highest concentration of plant roots and is more fertile than the other layers.

Nutrient management includes managing the composition of the soil. Minerals, organic material, water, and air are the fundamental elements of soil. Typically, 45% of the soil is made up of minerals. 5% organic material 20–30% water and 20–30% air are used. At best, these percentages are merely generalizations.
Numerous nutrients are found in soil, which are obtained from dead plants and animals. The plants eat these nutrients as nourishment. So soil contributes to the growth of plants by giving them sustenance in the form of nutrients.

Describe what happened when Mendel crossed purebred tall pea plants with short pea plants

Tomtit [17]

He found that the recessive trait such as the short plants disappeared, but only the dominent trait stayed which is tallness. When he allowed them to self pollinate, the recessive gene which is the shortness reappeared.

Dendrite is to axon what ________ is to ________. A) receiving; sending B) sending; receiving C) reuptake; action potential D) a

svlad2 [7]

Answer: Option A) receiving; sending

Explanation:

The neuron is made up of many parts, they include:

- dendrites, which are branched and helps in receiving impulses from the adjacent neuron

- axon, a long and extended portion of the neuron that the transmission of impulses along its length away from the cell body.

- synapse etc

Thus, dendrites of neurons is involved in receiving impulses into the neuron, while axons is involved in sending impulses away from the neurons
