Which organisms demonstrate the well-developed social behavior called eusocial?

Biology

Vesna [10]3 years ago

6 0

Answer:

1. Ants, termites, and bees

Explanation:

Eusocial societies are common in insects. This type of behaviour is characterized by the fact that individuals fall into certain groups with certain behaviours. For example, think of worker bees and the queen bee. These societies are associated with a few features:

the offspring are cared for by individuals other than the parents -many members in the group can cooperate to take care of the young.
labour is divided into reproductive and non-reproductive groups. Only the reproductive individuals are able to have offspring, the others help with parental care, gathering food, and maintaining shelter.
this creates groups, sometimes called 'castes', that animals fall into. They do not deviate from these groups once they are established.

Unsaved Nerve cells called _______________ form networks within the body (like a system of wires), in order to communicate with

Dafna11 [192]

The correct answer is "neurons".
Neurons are nerve cells which connect to each other using synapses and form neural networks. They exhibit high levels of specialization and are the primary components of the central nervous system.

Myofibrils are contractile fibers which form the striated muscle cells. Sarcomeres are the structural unit of the myofibrils.

The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0

devlian [24]

Answer:

volume = 0.285 L

Explanation:

Henry constant is given as

$Henry constant = \frac{C}{P}$

Where C is concentration

P is atmospheric pressure

$Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm$

when atmospheric pressure 4 atm

$solubility = K_H\times P$

$= 0.0007 \times 4 = 0.0028 M$

In 5 litere blood , moles of N_2 $= Molarity \times volume$

$= 0.0028 \times 5 = 0.014$

At surface moles $= 0.0056 \times 5 = 0.0028$

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of $N_2 = 0.0112 \times 28 = 0.314 g$

T = 37 + 273 = 310 K

$VOLUME = \frac{nRT}{P}$

$= \frac{0.0112\times 0.0821\times 310}{1}$

volume = 0.285 L

Which of the following behaviors allows a bird to maintain a constant body temperature in extremely hot weather?

patriot [66]

d. All of the above

These behaviors;

Spreading wings
Flattening feathers
panting

are all evolutionary process to maintain body temperature. Birds are warm-blooded animals. Also known as homeotherms, which is defined as having the constant body temperature. This is a vital function for the survival of the specie.

----

c. are hollow

The bones of most birds are hollow in order for the weight of the birds to be light for them to fly.
