Answer:
You are driving your 1500 kg car at 20 m/s down a hill with a 5.0⁰ slope when a deer suddenly
jumps out onto the roadway. You slam on your brakes, skidding to a stop. How far do you skid before stopping if the kinetic friction force between your tires and the road is 1.2 X 104 N? Solve
this problem using conservation of energy.
Explanation:
Hybridization is categorized as crossing organisms that have different traits to bring together the best of each. However, this can come with some post-zygotic barriers.
Reduced hybrid viability: hybrid offspring does not survive
Reduced hybrid fertility: hybrid offspring cannot reproduce
hybrid breakdown: first generation of hybrids are viable and fertile, however, their offspring (generation 3) are sterile.
Answer:
The correct answer is the letter b. The endosymbiotic event that brought chloroplasts into Eukaryotic cells actually happened after Eukaryotic lineages diverged so many lineages never actually possessed chloroplasts
Explanation:
The plastid is an organelle linked to membarna found in the cells of eukaryotic organisms, which contains pigments used in photosynthesis. Some eukaryotic organisms over time have inherited the ability to photosynthesize from cyanobacteria by secondary endosymbiosis or ingestion, and are able to capture and sequester photosynthetic cells and chloroplasts, this process is known as kleptoplasty.
This change demonstrates that some characteristics can be lost in evolution.
In the case of Chondrichthyes, boneless fish like sharks and rays, the skeleton made out of bones that were present in the common ancestor of them and other vertebrates was slowly changed for <span>cartilage which enabled these fishes to move agiler in the water.</span>
False! Climate change
The Earth used to be way colder than it is today
