Stop it you kid aaaaaaaaa
Answer:
Skeletal muscle can contract without shortening.
It can shorten (isotonic, concentration), elongate (isotonic,eccentric), or remain the same length (isomertric), depending on the relationship between the load (resistance) and the tension produced by actin-myosin interactions.
Answer:
Explanation:
Hemophilia is a X linked recessive genetic disorder caused by low amount of clotting factors. Hence, it becomes difficult to stop bleeding in case of an an injury and takes more time to clot. Here,
c= recessive allele for hemophilia gene
C= dominant allele for hemophilia gene
Genotype of male: XcY since he carries the recessive allele for hemophilia trait
Genotype of female: XCXc. She does not have hemophilia but her father had hemophilia so she she must have received one X chromosome from him and hence is a carrier for hemophilia.
Their children:
XcY X XCXc = XCXc, XcXc, XCY, XcY
Out of resultant genotypes 2 out of 4 i.e. XcXc and XcY show hemophilia trait hence there is 50% probability that the child will have hemophilia.
Answer:
Call 9-1-1 or the designated emergency number.
Explanation:
There is some evidence that mineral loss may be greater in athletes than in the sedentary population is true.
<h3>What causes mineral loss?</h3>
Simply not obtaining enough necessary minerals from food or supplements is a primary contributor to mineral insufficiency. There are various diets that could lead to this deficit. Possible factors include a poor diet that prioritizes junk food or one that doesn't include enough fruits and vegetables.
In addition to losing zinc and iron through urination, athletes can also lose salt, chloride, and potassium through sweat. The body can either enhance or decrease absorption in order to maintain mineral balance.
The following are some of the physiological functions of minerals that are crucial for athletes: bone health, muscle contraction, normal heart rhythm, nerve impulse conduction, oxygen transport, oxidative phosphorylation, enzyme activation, immunological processes, and blood acid-base balance.
