If white wool (W) is dominant over black wool (w), can two sheep with black wool produce an offspring with white wool? Explain y
Black_prince [1.1K]
No because it would look like ww to ww. So if you took a w from each parent the offspring would be ww/ have black wool. Say one parent had white wool that the offspring would be Ww so it is more likely to have white wool. Hope this helps

What causes chronic strains?
cricket20 [7]

Twisting or pulling a muscle or tendon can result in a strain. It can also be caused by a single instance of improper lifting or by over stressing the back muscles. A chronic strain usually results from overuse involving prolonged, repetitive movement of the muscles and tendons. In addition, there are several factors that put a person at greater risk for a back strain or sprain, including excessively curving the lower back, being overweight, having weak back or abdominal muscles, and tight hamstrings (muscles in the back of the thighs). Playing sports that involve pushing and pulling—such as weightlifting and football—also increases the risk of a low-back injury. Chronic strains happen slowly over time from prolonged, repetitive overuse of muscles. Chronic strains develop from using the same muscle groups in the same pattern, causing even small stresses to build on one another. Causes of chronic strain include:

Improper body mechanics or using the wrong muscle groups for a task, such as repeatedly lifting heavy objects using your back instead of your legs

Improper sports mechanics or techniques, such as habitually gripping a tennis racket too tightly or an incorrect golf swing

Participation in the same exercises in the same way, day after day

Poor posture

Use of the wrong equipment, such as running shoes without the proper support for your foot type

If you do strength training regularly you do not need to do cardio exercises to maintain good health
Solnce55 [7]

Answer:

The statement is "False."

Explanation:

Doing cardiovascular exercise is essential as doing strength training. Both have <em>different targets.</em> Strength training targets the <u>muscles of the body.</u> It promotes bone growth and makes you stronger. On the other hand, cardio exercise targets the <u>heart rate</u>. The more the heart pumps, the more oxygen the blood receives in the body.

Strength training gives you an<em> afterburn effect </em>that allows you to keep burning calories even after you workout, while cardio exercise allows you to burn more calories in a shorter span time–especially when you're doing <em>high-intensity exercise</em>.  

Clearly, both strength training and cardio exercise are essential.
