Active muscles demand huge amounts of oxygen, and the circulatory system works hard to provide it. Blood carries oxygen to the muscles. When the body is at rest, blood carries nutrients to the muscles so that they can repair and rebuild themselves. Blood also carries away the waste products that hard-working muscles produce, back out through the lungs to be filtered.
so they Circulatory system xx muscular system :)
Answer:
. Experimentation is the heart of science. Scientists ask questions, gather evidence, share ideas, and analyze data. In designing an experiment, the specific question (or questions) that the experiment is meant to answer must first be clearly identified.
Explanation:
Answer:
Knee.
Explanation:
Joints may be defined as the articulation by which the bones meet together and constitute the skeletal system. These joints helps in the particular movement of the body.
Tensor fasciae latae muscle is present in the thigh. This muscle is attached with tibia and innervated by the super gluteal nerve that supplies the blood artery. This muscle plays an important role in the stabilization of the knee and the hip joint.
Thus, the correct answer is option (c).
It has meanwhile been shown that the most sensitive cells are those that areundifferentiated, well nourished, dividing quickly and highly active metabolically. Amongst the body cells, the most sensitive are spermatogoniaand erythroblasts, epidermal stem cells, gastrointestinal stem cells.
Hoped this helped!
Answer:
Tt - 1/2
tt - 1/2
Explanation:
<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>
Tt x tt
Offspring = Tt Tt tt tt (50% tall and 50% short)
If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):
Tt x tt
Offspring = Tt Tt tt tt
Genotype ratio = 2Tt:2tt
Hence,
Tt = 1/2
tt = 1/2
