How do LED lights differ from fluorescent lights?LEDs emit light by concentrating wavelengths of light; fluorescent bulbs emit light because of heat.
LEDs emit light because of energized solids; fluorescent bulbs emit light because UV light interacts with a phosphor coating.

Which statement best describes an understanding of genetics that would be missing without the work of Mendel?a. The DNA codes for traits would not be known.
b. The protein codes for traits would not be known.
c. Some alleles are dominant, and some alleles are recessive.
d. Offspring receive two copies of each allele from each parent.

Answers

The answer is c. Some alleles are dominant, and some alleles are recessive.

Gregor Mendel established the principles of heredity. To explain his experiments and discoveries, he invented terms dominant and recessive in reference to traits.

The other statements are not true because the DNA and protein codes were researched and discovered almost a century after Mendel's work. The statement that offspring receive two copies of each allele from each parent cannot be true since offspring receive only one copy of each allele.

Answer:

C. Some alleles are dominant, and some alleles are recessive.

Explanation:

Phylogeny is the type of classification that names and identifies different organisms primarily by their: A. Physical similarities B. Similarity to humans C. Physical differences D. Evolutionary relationships

Answers

Phylogeny is the type of classification that names and identifies different organisms primarily by their evolutionaryrelationship. The correct option is D.

What is phylogeny?

Phylogenetics is the analysis of the evolutionaryhistory and interactions between or within organism groups in biology.

Phylogeneticinference methods that concentrate on observed heritable traits, including such DNAsequences, protein amino acid sequences, or morphology, are used to determine these relationships.

Thus, the correct option is D.

What are stem cells and how are they being used?

Answers

Answer:

Stem cells are special human cells that are used to repair damaged tissues

Answer:

In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and divide indefinitely to produce more of the same stem cell. Stem cells are undifferentiated cells that can turn into specific cells, as the body needs them. Scientists and doctors are interested in stem cells as they help to explain how some functions of the body work, and how they sometimes go wrong.

Which of the following chemical reactions proves the fact that the products of photosynthesis are reactants of respiration?Photosynthesis:
Respiration:

Photosynthesis:
Respiration:

Photosynthesis:
Respiration:

Answers

The answer is:
Photosynthesis: 6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP

Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose (C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and oxygen (O₂).

photosynthesis: C6H12O6 = 6 O2 + 6 CO2 + 6 H2O

breathing: C6H12O6 + 6 O2 6 CO2 6 H2O ATP
