The phenomenon of populations of organisms changing from generation to generation is known as biological evolution.

<h3>What is biological evolution?</h3>

Biological evolution is a scientific term that deals with the change in inherited traits through successive generations in an organism's population. For example, penguins have typical wings over swim-friendly flippers which were there for many generations. It is also called microevolution. Biological evolution is important because it helps us to understand why an organism is the way they are. Mutation, genetic drift, gene flow, and non-random mating are some of the causes of biological evolution. Heredity and Reproduction are the top conditions for biological evolution.

Two true-breeding pea plants are crossed, one with purple flowers and the other with white. their offspring are

Verdich [7]

Knowing that purple flowers are dominant (have a higher percentage of passing certain information to offspring) and white a recessive (have a much lower chance of passing certain information to offspring) the plants of the $F_{1}$ generation (first generation bread) will be all purple.

When a white-flowered pea reproduces with a purple-flowered pea all of the offspring will be purple.

When 2 offspring (purple-flowered) of the $F_{1}$ generation breed, there is a 15% percent chance of offspring being white-flowered.

Answer:

$\boxed{\bf~The~offspring~will~be~purple-flowered.}$

How is heart rate collected during the ymca 3-minute step test to evaluate the cardiorespiratory fitness level of an individual?

vredina [299]

It is measured over a 60-second count immediately following the test.

After completing the test, the individual sits while the fitness professional palpates the radial pulse (within 5 seconds of test completion) and measures the number of heartbeats over the ensuing 60 seconds.

<h3>What is cardiorespiratory fitness?</h3>

Cardiorespiratory fitness (CRF) refers to the ability of the cardiovascular and respiratory systems to oxygenate the mitochondria of skeletal muscle for the energy production required during physical activity. CKD is an important indicator of adolescents' physical and mental health and academic performance.

Forms of exercise that rely on cardiorespiratory endurance include strenuous distance running, swimming, and cycling. This aspect of fitness also affects your ability to perform low-intensity, sustained, full-body exercises, such as walking, without feeling undue fatigue.

Walking briskly, climbing stairs, doing household chores. High levels of physical activity and cardiorespiratory fitness (referred to simply as “fitness” in this article) are associated with reduced all-cause and cardiovascular mortality. In addition, physical activity can reduce the incidence of chronic diseases such as hypertension, diabetes, stroke and cancer.
