Explanation:
True, because ribosomes are where RNA is transferred into proteins that speed up the process.
Which of the following best describes the connection between cardiovascular disease and age?
O A. As people age, their blood vessels become more elastic leading to less cardiovascular disease.
O B. As people age, the heart becomes more efficient with each pump, increasing cardiac output
O C. As people age, blood pressure decreases leading to more cardiovascular disease.
O D. As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
<h2><u>Answer:</u></h2>
- D. As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
Plaque development can restrict these arteries, reducing blood flow to the heart. Reduced blood flow may eventually result in chest pain and shortness of breath A heart attack might be caused by a total blockage.
How
often an allele occurs in the gene pool is allele frequency.
<span>Allele
frequency defines how common an allele is in a population. It can be calculated
by counting how many times the allele appears in the population and then
dividing by the total number of copies of the gene.</span>
Answer:
Weather is the day-to-day conditions, and climate is the conditions expected over relatively long periods of time.
Explanation:
The difference between weather and climate is how long the period of time they refer to is.
Weather is what conditions of the atmosphere are over a short period of time, or day-to-day conditions. It's what we see on the weather forecast every day - whether it's going to be sunny or rainy today and tomorrow and similar.
Climate is what conditions of the atmosphere are over longer periods of time, usually 30 years. In fact, it's an average pattern of weather for a particular region. A description of a region's climate will include the precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, frost, and hail storms, and similar conditions.
