Blood groups are inherited from both parents. The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles inferred from classical genetics: i, IA, and IB. The I designation stands for isoagglutinogen, another term for antigen.
The steatite seals found in the Indus valley resemble seals found at contemporary sites in Mesopotamia.
The steatite seals are also referred to as the Pashupati seals and are found in major regions of the Indus Valley civilization.
Scientists have managed to find a variety of seals that belongs to the Harappan site of the Indis Valley civilization.
These seals have also been known to be founded in the Mesopotamia region. Scientists are researching and finding evidence that the steatite seals found in the Indus valley and Mesopotamia may belong to the same ancestors and might have migrated over time.

Answer: a. Blood and mucus in the stools.
Explanation:
Diarrhea is a gastrointestinal problem. It is associated with the symptoms of loose stools, cramps, vomiting, fatigue, and stomach pain. The diarrhea usually last for few days to week. It is also associated with the signs of dehydration due to loss of fluid through loose stools like stretchiness in skin, loss of color of skin, and fast heart rate. The diagnostics of diarrhea can be done by examining the blood and mucus in the stool.
Answer:
Group behavior, also known as collective behavior, <u>can increase the chances for a species to survive and reproduce because they can rely on each other to accomplish behaviors that are crucial for their survival, such as hunting, migrating, and breeding.</u>
Explanation:
According to ethologists, social species highly depend on the members of their own group for survival. One perfect example is the case of <u>schooling fish</u>. These small species of fish gather in a whole large group and navigate long distances while looking for food. Researchers from Princeton University <u>discovered that their orientation capabilities increased when more individuals joined the group, making them more responsive to the environment.</u>
<u />
Moreover, there have been numerous sources of evidence that demonstrate that <u>orcas (killer whales)</u><u>,</u> which are extremely social creatures<u>, create large pods of around 20 to 30 individuals and 'plan' strategies to hunt. Also, older females swim along younger individuals to teach them hunting skills that are crucial for their survival.</u>
<u />
In addition, <u>herbivores</u>, like zebras, <u>are usually found in large groups because it lowers the possibilities of being individually targeted by apex predators, such as lions.</u>
<u />
Recently, researchers have also discovered that <u>migrating species</u><u> often rely on each other to improve their migrating capabilities by producing or generating social cues that allow them to improve their orientation or in cases when environmental conditions get tough</u> (Source).
In conclusion, these lines of evidence show that social organisms who travel in groups rely on all members to carry out important behaviors that, without them, would provoke an important decline in their populations because they wouldn't be able to reproduce or feed individually as successfully as they would with the 'help' of the members of the group.
