Human blood groups are governed by three alleles, IA, IB, and i. IA and IB are codominant and i is recessive to both. A man who
Ira Lisetskai [31]

Answer:

They could have all four type phenotype that are A, B, AB, and O

Explanation:

If the man has A blood group and the woman has B blood group then the genotype of man can be IAIA or IAi and the genotype of woman can be IBIB or IBi.

               IA      i

       IB   IAIB   IBi

       i     IAi       ii

So if the genotype of the parents are IAi and IBi then out of four offspring one could have AB blood group, second could have B blood group, third could have A blood group and fourth could have O blood group as shown in the cross above.

Sea urchins tend to have great camouflage because they sometimes carry what two animals on there shells?​
Fudgin [204]

Sea urchins tend to have great camouflage because they sometimes carry algae and rocks on their shells.

<h3>What is camouflage?</h3>

Camouflage is a defense mechanism used by certain organisms to avoid predation or surprisingly attack their prey.

Different animals possess different camouflage mechanisms. For example;

  • Chameleons change their color to that of their immediate environment
  • Certain snakes hide in vegetations that blend with their skin color.

However, sea urchins are aquatic animals that tend to have great camouflage because they sometimes carry algae and rocks on their shells.

there are few calls in the vocal communication system of apes, and any particular call is produced only when the animal finds it
True [87]

They communicate with smells, sounds, visual messages, and touching.

<h3>Vocal Communication in Primates:</h3>

Animals frequently communicate through voice. In order to trace the evolutionary roots of our sophisticated communication system, researchers frequently study vocal communication in nonhuman primates (primates) with the goal of detecting similarities and differences between human language and speech. Listeners appear to comprehend the meaning of the sounds made by primates in response to particular occurrences, such as the discovery of a particular predator. Although this form of communication and human referential words appear to be similar on the surface, the mental processes that underpin them may be extremely different.

There is far more disagreement regarding whether the production of ape vocalizations and language share any similarities, despite the fact that generally speaking, the flexibility displayed by primate receivers may exhibit some similarities with humans. It is generally acknowledged that primates, unlike humans, cannot produce novel vocalizations.
