Pietro has two dogs that are related, and he wants to understand why one of the dogs has tan fur and the other has brown fur.
Which pattern of inheritance would explain the different fur color in the related dogs?
Polygenic inheritance is simply a form of inheritance whereby the trait of the individual or the animal is gotten from the cumulative effects of several genes. In such case, there are many genes which control the expression of the trait. This is quite different from the monogenic inheritance whereby the trait is as a result of the expression of just only one gene.
Since Pietro has two dogs that are related, and one of the dogs has tan fur and the other has brown fur, then this means there's more than one gene which is expressed in this case.
In conclusion, the answer to the question is polygenic inheritance.

Which list identifies the order of events that formed a volcanic crater?
A) CBDA
B) BACD
C) CADB
D) DBAC
Based on the given image, the order of events that formed a volcanic crater is CADB. Thus the correct option is C.
What is a volcanic crater?A nearly circular hole in the ground produced on by volcanic eruptions is known as a volcanic crater. It is a valley that typically stands just above the eruption where volcanic debris is emitted, and it has the shape of a bowl or funnel.
During volcanoes, craters' dimensions and shapes could alter. A volcanic crater, also known as a caldera, is a sizable depression created when a natural disaster occurs and then collapses.
Underneath the surface of the Earth, the molten rock is known as magma. Less dense than normal lava is being pushed upward to the surface by intense pressure. When magma seeps through layers of preexisting rock, it forms another structure.
Therefore, option C is appropriate.

Jorge is testing the effect of lead on child development. Based on his observations, he finds that the longer the children are exposed to lead-based paint, the higher the chance becomes that the children may develop behavioral problems. He has done repeated experiments, and his results are similar to the results of many other scientists.
Why is this scenario considered a theory rather than a hypothesis?
It is a testable scenario.
It is based on prior knowledge.
It is a well-tested explanation.
It is a factual statement.

none of the above
Answer:
electrical impulses
Explanation:
why might scientists be wary of the results of a single experiment testing a particular treatment, even when the results are peer reviewed and statistically significant
Answer:
The results may not be true for humans if the experiment used a model organism.
Explanation:
An animal model is an animal species used in research that mimics diverse human traits/features such as, for example, human response to certain diseases. Thus, animal models may provide useful information related to human developmental biology and human diseases (i.e., prevention, diagnosis, treatment, etc). However, in general, experiments involving animal models cannot be used to predict human outcomes. For example, in genetics, animal models exhibit different features to humans, including but not limited to genomes (i.e., different number and structure of chromosomes), genes, gene regulatory pathways, epigenetics gene regulatory mechanisms, etc. In consequence, animal tests may be unreliable and therefore their results cannot be directly extrapolated to human subjects.
Which action would NOT be controlled by the somatic nervous system?
A Nodding your head
B. Sneezing
C. Petting a dog
D. Jumping over a puddle
Answer:
B. Sneezing
Explanation:
There are two types of nervous systems namely: somatic nervous system and autonomic nervous system. The somatic nervous system is that nervous system that controls the voluntary movement of muscles while the autonomic nervous system controls involuntary actions.
According to this question, nodding ones head, petting a dog and jumping over a puddle are all examples of voluntary movements, hence, are controlled by the somatic nervous system whereas, sneezing is an involuntary action controlled by the autonomic nervous system.

Black bears in the north hibernate mostly due to the scarcity of food during the winter months.
Prior to hibernation bears are foraging for food. They eat fruit, nuts, acorns, insects, and certain leaves and plants. They catch occasional small animals, but lack agility to catch most adult prey. In the months before hibernation black bears can gain up to forty pounds of fat per week.
9. What types of food molecules is the bear consuming (give at least two)?
Answer:
Food having high fat.
Explanation:
The bear eat food products having high fats in order to store it in the body. The food which have large amount of protein and fats are stored in the body and helps in gaining of weight up to forty pounds of fats per week. During hibernation period, bear used this fats for the release of energy used for its survival. Fats produce huge amount of energy when they are broken down so this fats helps in hibernation of bear.
