Answer:
Steel
Explanation:
In fact, sound waves travel over 17 times faster through steel than through air. Sound waves travel over four times faster in water than it would in air
The correct answer is B, internal intercostal muscles and abdominal muscles would contract.
Exhalation is the flow of the breath out of the body. During forced exhalation, internal intercostal muscles contracts which lower the rib cage and decrease thoracic volume, while the abdominal muscles push up on the diaphragm which causes the thoracic cavity to contract.
Answer:
<u>Part A</u> : 70 secondary oocytes will be formed.
<u>Part B</u> : 70 first polar bodies will be formed.
<u>Part C</u> : 70 ootids will be formed.
Explanation:
During oogenesis growth maturation of a single oogonium produces one primary oogonium.
the primary oogonium then undergoes meiosis -1 and produces one secondary oocyte and first polar body.
The secondary oocyte then undergoes meiosis - 2 and forms an ootid and second polar body.
The ootid then differentiates into the ovum.
As in the above scenario , 70 primary oocytes are present , they undergo meiosis-1 and produces 70 secondary oocytes and 70 first polar bodies. Hence answers of part A and B is 70.
As 70 secondary oocytes are formed , they undergo meiosis -2 and forms 70 ootids which then differentiate in 70 ovums.
Cooperation is common in non-human animals. Besides cooperation with an immediate benefit for both actors, this behavior appears to occur mostly between relatives.[1] Spending time and resources assisting a related individual may at first seem destructive to the organism’s chances of survival but is actually beneficial over the long-term. Since relatives share part of their genetic make-up, enhancing each other’s chances of survival may actually increase the likelihood that the helper’s genetic traits will be passed on to future generations.[6] The cooperative pulling paradigm is an experimental design used to assess if and under which conditions animals cooperate. It involves two or more animals pulling rewards towards themselves via an apparatus they can not successfully operate alone.[7]
