Self-awareness can be demonstrated by both humans and animals if they:.
AlladinOne [14]

Answer:

Appear to be aware of life and death, understand it, and can understand the effects of their actions.

Explanation:

Most animals are aware that they will die, however certain animals, such as elephants, seem to be more aware of the permanence of death, resorting to violence towards other animals typically only when absolutely necessary. The understanding of the effects of their actions is often seen through caring for young and ending fights before a death occurs, which is often seen in big cat species, where, when fighting for dominance, makes will often roll over to signify forfeit.

Can someone help me with a biology related question? I'm offering good points!!!!! Help me out please.
miss Akunina [59]
First, write out all combinations for the parents:
<u>SsBB</u>:
SB
sB
SB
sB

<u>ssBb</u>:
sB
sb
sB
sb

So now that you know what to put on as the x and y for the Punnett Square, set it up:

<u>     |    SB   |    sB    |   SB    |  sB     </u>
<u>sB | SsBB |  ssBB |  SsBB |  ssBB </u>
<u>sb | SsBb |  ssBb  |  SsBb |  ssBb </u>
<u>sB | SsBB |  ssBB |  SsBB |  ssBB </u>
<u>sb | SsBb |  ssBb  |  SsBb |  ssBb </u>

Now, listing each possible genotype and the number of times they show up in the square:
SSBB
0 times
SSBb/SSbB
0 times
SSbb
0 times
SsBB/sSBB
4 times
SsBb/SsbB/sSBb/sSbB/
4 times
Ssbb/sSbb
0 times
ssBB
4 times
ssBb/ssbB
4 times
ssbb
0 times

Since there are only 4 genotypes are possible, set up ratios of those four:

SsBB:
4 times/16 total = .25 = 25%

SsBb:
4 times/16 total = .25 = 25%

ssBB:
4 times/16 total = .25 = 25%

ssBb:
4 times/16 total = .25 = 25%

This means that the<em> genotypes</em> have a 25% : 25% : 25% : 25% likelihood.


Now, let's figure out the phenotypes of the 4 genotypes:
SsBB:
Ss = dominant
BB = dominant

SsBb:
Ss = dominant
BB = dominant

ssBB:
ss = recessive
BB = dominant

ssBb:
ss = recessive
Bb = dominant

So we have 2/4 that are S-dominant B-dominant and 2/4 that are S-recessive B-dominant.
This means that the phenotypes are:
2/4 = 50% Thin stripes with black eyes, and
2/4 = 50% Thin stripes with gray eyes.

I hope this helped you out :)

Why have so many bacteria now able to resist antibiotics
bekas [8.4K]

Answer: Because they have built up immunity from past medications.

Explanation: As people get sick and are given antibiotics the 99.9 % are removed but that one percent from the bacteria is able to overcome the antibiotics and make itself stronger and immune to the medicines, then the bacteria evolves and a new person will get infected and will need stronger antibiotics further more the cycle is repeated.
