ANSWER: None of the above options are correct.
Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)
Therefore where HR= 90bpm and SV= 110ml/min,
CO = 90 × 110 = 9900ml/min or 9.9L/min.
EXPLANATION:
CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.
Cardiac output is the product of two variables, stroke volume and heart rate.
STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.
HEART RATE is the count of the number of times the heart beats per minute.
Sensory nerves that are part of the peripheral nervous see your arm. Nerve impulses are brought to the brain by interneurons and the brain processes the information and you decide to lift your arm. Nerve impulses from the brain travel again through internuerons and into motor nerves that control the movement of your arm.
Answer:
During photosynthesis the tree while convert the energy from sunlight into sugar (glucose). The xylem will transport the water to the leaves. The phloem will transport the glucose. The energy from sunlight will also be used to convert water and carbon dioxide into oxygen and glucose. Hence, the energy stored within the glucose/sugar molecules will be used to help the tree grow.
Explanation:
I wrote it in my own words but it will probably say i took it from go ogle since used similar terms apparently.
hope this helps and is right. p.s i really need brainliest :)
Nitrogen released from dead matter goes into soil, helping/feeding the plants, who in turn give us oxygen
The correct sequence of these events (origin of mitochondria, origin of multicellular eukaryotes, origin of chloroplasts, origin of cyanobacteria, origin of fungal-plant symbioses), from earliest to most recent, in the evolution of life on earth is 4, 3, 1, 2, 5.
The transition to eukaryotic cells seems to have taken place in the Proterozoic Era, around 1.2 to 1.5 billion years ago. Nevertheless, the latest genetic studies propose the divergence of eukaryotes from prokaryotes nearer to 2 billion years ago.
Margulis suggested the mechanism of endosymbiosis, to describe the origin of mitochondria as well as chloroplasts from persistent living prokaryotes. In accordance with this idea, a bigger prokaryote engulfed or enveloped a smaller prokaryote around 1.5 billion to 700 million years ago.
