Explanation: Think about how the sun is positioned in the sky. If it was noon, the sun is above the stick which means little to no shadow at all. If the sun was rising, its hitting one side of the stick, making the shadow longer.
<h2>Material Do Alice and Julio Likely Work - Option B</h2>
Alice and Julio’s company makes protective coverings for off-roading vehicles. Alice’s job involves harvesting a natural polymer from trees. Julio’s job is to take that material and change it chemically to create a synthetic polymer.
Alice and Julio most likely work with natural rubber and vulcanized rubber. Alice works with natural rubber, and Julio works with vulcanized rubber.
The correct answer is: B. In sexual reproduction, individuals transmit half of their nuclear genes to each of their offspring.
The main difference between sexual and asexual reproduction is that in sexual reproduction genetic material from two parents is combined, while in asexual reproduction produced offspring is genetically identical to the one parent. So, advantage of sexual reproduction is that produced unique organisms contribute to genetic diversity (variation is formed). But, comparing to asexual reproduction, sexual reproduction requires more energy and lasts longer.
Asexual reproduction is found in lower organisms and can be in different forms: budding, vegetative reproduction, fragmentation, spore formation.
Answer:
Na+ only
Explanation:
Depolarisation of membrane refers to the change in the resting membrane potential of the membrane of a cell which is usually -70mv to a more positive value.
This value changes when the positive ions move inside the cell which increases the positive charge inside the cell.
In the myocardial cell, the sodium ions move inside the cell which changes the potential towards the more positive side as a result of which the signals for contraction arises.
Thus, Na+ only is correct.
