<span>ENZYMES ARE PROTEINS. All proteins are made up of amino acid.. Enzymes are used as catalysts in metabolic reactions in living organisms. They help to speed up the rate of chemical reaction but they are not used up in the reaction. Enzymes requires optimum conditions to function optimally. </span>
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.
1. I’m not really sure how to answer it, i think it’s parasitic
2. The tick is the parasite since the human is the host
3. It’s symbiosis bc it’s a long term biological interaction between two different biological organisms (the human and the tick) and in this case it’s parasitic bc one benefits off the host but it’s harmful towards the host so it doesn’t benefit each member.
Hope that helps :)
Answer:
One-half of the daughters of an affected man would have this condition.
Explanation:
Each daughter born to a woman that is positive for a dystrophin mutation on one of her two X chromosomes possess a 50 percent likelihood of possessing the mutation and also becoming a carrier. Carriers at times do not show the disease symptoms but may give birth to a child that has the mutation or the disease condition. DMD carriers do have a higher chance of cardiomyopathy.
A man with DMD cannot transfer the affected gene to his sons since he passes to his son a Y chromosome, not the X chromosome. But he will definately transfer it to his daughters, since each daughter possess her father’s only X chromosome resulting in the daughters being carriers.
Hence, One-half of the daughters of an affected father and a carrier mother could have this condition.
