Answer:
In guinea pigs, the gene for black fur, B, is dominant over the gene for white fur, b. Complete the Punnett square below to show the results of one possible cross between two guinea pigs with black fur.
BB X Bb = BB, Bb, BB, Bb
Explanation:
From the analogy shown, it is obvious that both parents are gene with black fur. During such crossing, the offspring are two homozygous dominant black fur and two heterozygous dominant black fur
Asymmetrical organisms tend to be LESS complex than symmetrical organisms.
Asymmetrical organisms are those organisms that have primitive body plan, example of these are sponges. The symmetrical animals are much more developed in their body plans and layouts.<span />
When blood calcium levels drop, glands embedded in the posterior thyroid secrete parathyroid hormone, which stimulates osteoclastic activity. It is made up of parathyroid glands that lie behind the thyroid glands. The reason why it is important because it controls calcium level in the blood and within the bones. It controlled by the low calcium levels in the blood it restorative parathyroid secretion whereas the high calcium levels in the blood stop the release of parathyroid hormone.
Answer:
Classification of organisms is done while considering many factors such as:
Cell type- whether the organism is prokaryotic or eukaryotic
Cell structure- This includes both the presence and composition of the cell wall
Body type- whether the organism is multicellular or unicellular
Mode of nutrition- the method through which the organism achieves its nutritional requirement, by consuming other organisms (heterotroph) or making its own food (autotroph)
As human travel increases , the number of introduced species likely increases .
<h3>What is species and how human travelling can increase the number of introduced species?</h3>
- As humans will start moving more from one place to another there will be more species number.
- The number of introduced species will increase sharply seeing the increase in the number of human population doing migration and travelling.
- The breakdown of regional distinctiveness leads to increase in the travelling period of the humans .
- And most importantly the introduction of new species will increase and will be impacted by the human who have come from elsewhere for either travelling purposes or migration purposes.
