In a population under balancing selection, why can a deleterious recessive allele remain at a stable frequency despite reducing overall fitness?
A deleterious recessive allele can remain at a stable frequency under balancing selection because the fitness advantage it provides in heterozygotes outweighs the disadvantage in homozygous recessive individuals.
what are the building blocks of DNA called?
Nucleotides
Bacteria scientists sort bacteria into 2 groups name them:
scare biosphere taxa (microbes that make up less than 0.1% of a microbial community) and endemic/isolated pathogens.

Explain how photosynthesis works.
Photosynthesis is the process plants, algae, and some bacteria use to convert sunlight into chemical energy stored as glucose (a type of sugar). It also produces oxygen, which is released into the atmosphere.
This enzyme's 3 to 5 exonuclease activity provides a reading during DNA replication, lowering mutation rates by removing incorrectly paired nucleotides before polymerization continues. in bacteria, this activity is associated with DNA polymerase III in eukaryotes, it is performed by DNA polymerases δ and ε. Name this error-correcting activity.
Proofreading exonuclease activity (PEA)
Why does carbon monoxide poisoning reduce oxygen delivery to tissues even when the lungs are functioning normally?
By creating carboxyhemoglobin, altering hemoglobin's shape, and disrupting cellular respiration. Even with healthy lungs, the body cannot effectively transport or use oxygen.

Which cell part is known as the powerhouse of the cell?
Mitochondria
What is the difference between a white blood cell and a red blood cell?
Red blood cells carry air-rich blood around your body while white blood cells fend off viruses or diseases.
What enzyme unwinds DNA during replication?
Helicase
What is the largest organ in the human body?
The skin
what comes after 4?
What is our 2025-2026 team number for art history?
Team #4794
Why can a harmful recessive allele remain in a population for many generations?
because it can hide in heterozygous carriers where it does not affect survival.
What molecule carries amino acids to the ribosome?
tRNA
