The DNA molecule has a ladder-type structural organization. Each rung of this ladder represents a pair of nitrogenous bases #leregentsreview

Certain insects resemble the twigs of trees. Based on modern evolutionary theory, the most probable explanation for this is that natural selections of many variations had occurred #leregentsreview

The hereditary factors proposed by Mendel are now known to be composed of DNA #leregentsreview

Plasma membrane and cytoplasm are found in all living cells #leregentsreview

Oxygen is needed for aerobic cellular respiration to occur #leregentsreview

[jtravis @jtravisflhs]

Heterotrophs use free O2 for respiration but can not make their own food. An example of a heterotroph is a human. #leregentsreview

After a cookie has been digested, molecules enter the bloodstream by the process of diffusion #leregentsreview

Two cuttings taken from the same parent plant may differ in phenotypes when they are grown in separate containers. This difference is most likely due to environmental factors. #leregentsreview #phenotype

Heredity is the passing on of genetic traits #leregentsreview

[jtravis @jtravisflhs]

RNA stands for ribonucleic acid, and they serve as messengers from the DNA to the ribosomes for protein synthesis. #leregentsreview

Due to carbon emissions and other anthropogenic factors, those tree rings have been thin in recent years #carbon #treerings #globalwaeming #climatechangs @FLHS_emorales @FLHS_Brett

How do tree rings teach us about our changing climate? The rings are thinner in years when it’s dry. Thanks to new @NASAEarth data, we now know that human-generated emissions have been affecting global drought since the early 20th century. Stay informed: https://t.co/zamU25aUzR

This year's average concentration of atmospheric carbon dioxide is up about 2 ppm since last March. We need to reduce carbon emissions because it is greatly affecting our climate#carbon #climatechange #globalwarming

[ARCHIVED - NASA Climate @NASAClimate]

Last month's global average concentration of atmospheric carbon dioxide (CO2) was about 410 parts per million (ppm), up about 2 ppm from March 2018. https://t.co/qjYgQZI1Al

Private owners were “angry & disappointed” that South Africa did not table a rhino horn trade proposal for the upcoming '@CITESCoP18 in Sri Lanka. The decision was “unacceptable, illogical & indefensible” https://t.co/wqlk5jAmoz

Requirements for a second habitat for Javan rhinos: must be accessible for long-term management & safe from poaching & habitat destruction (unlikely to be hit by a tsunami, earthquake, volcanic & landslides; & must have diverse vegetation https://t.co/wXRk7j8Xtp

There are only 2 Northern White Rhinos left!!! Buy products without palm oil so this doesn’t happen to any other species! #passonpalmoil

[Save the Rhino International @savetherhino]

Lovely profile of James Mwenda, who works at @OlPejeta in Kenya, & who acts as caretaker for the last two Northern white rhinos https://t.co/ovIp52aj42

[jtravis @jtravisflhs]

Pass on palm oil and help save the rhinos! Their homes are being destroyed for your snacks! #PassOnPalmOil

Cricketing superstar Kevin Pietersen (@KP24) is spending his retirement fighting to save the rhino. KP speaks about his new documentary, how bad the situation is, and he also shares his thoughts on Warner and Smith. #TheProjectTV

Owls and mice have a predator / prey relationship #predator #prey @FLHS_Mberisha @FLHS_Brett @flhsemorales

[jtravis @jtravisflhs]

The relationship between humans and ticks is parasitism, because ticks benefit but humans are harmed #parasitism @FLHS_Mberisha @FLHS_Brett @flhsemorales
