Answer:
Explanation:Compounds which have carbon and hydrogen atoms in their structure or formula are known as organic compounds. For example, a molecule of is organic because it has carbon and hydrogen atom in its formula. ... Thus, we can conclude that an organic molecule will always contain carbon and hydrogen
A chemical reaction bonding monomers together to make a polymer
Answer: Contractile vacuole of amoeba will shrink/contract when the organism is placed in sea water.
Contractile vacuole is a subcellular structure ( mainly found in protists) that is involved in the regulation of water quantity inside a cell.
As we know that water always flow from a hypotonic ( where solute concentration is less) to a hypertonic ( where solute concentration is more) solution. Sea water is a hypertonic solution as the concentration of salt is very high. Therefore, in this case, water will flow from contractile vacuole to outside of the organism.
Thus, contractile vacuole of amoeba will contract as it will lose water when placed in sea water.
Answer:
Percentage of food eaten by the flock
Why is the percentage of food eaten a good number to use? Explanation:
A percentage compares the number of birds in the flock to the total number of birds in all flocks.
If the percentage is high, the flock is more successful, so the flock should grow.
If the percentage is low, the flock is struggling to eat, so the flock should shrink.
Answer:
- 1/2 Aa Wx wx (colored seeds, normal starch)
- 1/2 aa Wx wx (colorless seed, normal starch).
Explanation:
- A (colored seed) is dominant over a (colorless)
- Wx (normal starch) is dominant over wx (waxy)
Both loci are independent.
A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).
- The homozygous recessive can only produce <em>a wx </em>gametes.
- The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>
<u>The possible offspring resulting from the combination of those gametes is:</u>
- 1/2 Aa Wx wx (colored seeds, normal starch)
- 1/2 aa Wx wx (colorless seed, normal starch).
