Answer:
Explanation:
Lets take an example of human primates -they communicate in a diverse way in their life cycle using gesture ,posture ,vocals ,expressions etc . The the humans are in their infant stage they cry when they feel hunger . No one teaches them to do so these are naturally done by then through natural instincts .They expresses their anger by making sounds . As we grow up we use all of our sense organ to communicate with the organisms and the environment . We uses verbal as well as non verbal communication depending upon the need . Human primates uses diverse ways to communicate ,visual expressions and gestures also speak alot .
communication increases fitness within the species as they talk about their need . Through communication only relationships and interactions established among primate. This can be used to communicate information among members of a troop that can increase the fitness of a collective group . As we know that as a community we share responsibilities ,so if the communication is strong life expectancy increases in many primates (such as monkey , tigers and dears ) .
Answer:
The foot
Explanation:
Mollusks have bilateral symmetry and are coelomed protostomes, but the coelom is only represented by small residual spaces around the pericardial cavity, the gonads, some parts of the nephridia, and in some cases part of the intestine. The foot is used primarily as a means of movement. The foot is also a very important structure, although it has adapted differently depending on the classes of mollusks. It is characterized by having a really powerful and complex musculature. The most widespread use of this organ is that of locomotion, as happens with gastropods. However, in bivalves it serves to burrow or in cephalopods it helps to provide propulsion.
Answer:
Mutations are naturally caused by errors in DNA replication, by physical or chemical methods. The mutations change the genetic makeup of the organism and introduce new alleles or combination of alleles in a population. These random mutations accumulate over time and increase the genetic variation among the population.
Explanation:
Answer:
D.
Explanation:
an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of cyclonic weather systems.
Well I don't know much but I do know that they are different because unicellular can self produce which means they can reproduce without someone else but multicelluar needs someone else to reproduce
