Answer: Posterior HoxA and HoxD genes play important roles in patterning along the proximodistal axis of the forelimb (10–13). They also are required for activating and maintaining Shh expression in the developing forelimb (6, 7). mark brainliest
Explanation:
I think you just answered your question. They encourage adolescents to eat calcium-rich foods because it aids in bone formation, like you said.
When you take water from tank A then tank A salinity would not be less or higher so option A and B are out. The answer is depends on the relative salinity of tank A to tank B.
Assuming the tank A salinity is higher than B, then the tank B salinity will also become higher.
Answer: <span>d.the salinity in Tank B would be higher</span>
Ok, so when a horse (with 64 chromosomes) is crossed with a donkey(that has 62 chromosomes), each parent give its child half of its chromosomes. [64/2=32] [62/2=31]. So the mule gets 31 pairs of chromosomes plus 32 pairs of chromosomes. That equals 63 total chromosomes. In order to be a parent, it must give <span>half of its chromosomes to its child. [63/2=31.5] You can't have half a chromosome, so the mule is a sterile organism. Let me know if you have questions.</span>
Answer:
<em> The carrying capacity is determined only by the density-dependent factors.</em>
Explanation:
The maximum number of organisms of a particular species that an environment can hold is known as the carrying capacity of that environment. The carrying capacity depends on density-dependent factors as well as density- independent factors like weather, sunlight etc.
Beyond the carrying capacity, the organisms will begin to fight with each other for limited resources. The environment will become unstable as the resources will be scarce and individuals will be more.
