Is the current rate of species loss 10 times the typical rate of extinction?

Biology
1 answer:
Anika [276]3 years ago
7 0
The natural rate of extinction as assumed by science is about 5 species per year. Currently scientists estimate we are losing species at 1000-10000 times that rate, with multiple species disappearing every day. A note on this idea is that the average extinction rate gives an unrealistic depiction of nature when we consider the catastrophic extinction events that ended the dinosaurs and shaped the ice age.

In sexual reproduction how do the offspring compare to the parents
Diano4ka-milaya [45]
Well, if you want to get scientific about it, when two people have a kid, parts of what make them who they are go to that child, and the kid becomes a part of the parents. Basically, they have similar DNA. 
 A non scientific description of that would be they all have similar personalities because the mom and dad passed on some of them to the child. The child would be most alike to their parents by the subconscious actions they take, for example: how they take a shower. For kids who have step parents (me being one), if they grew up with that parent, they eventually adopt things the parent find interests in. Basically, the answer is in the subconscious actions they take and their personalities. <span />

The correct option is A.
Living organisms depend on their environment to survive, when there are changes in the environment which are not favorable to the living organisms, it will eventually leads to the wiping out of the living organisms. As time goes on and the environment recover, the living organisms that will be found in the new environment are those who will be able to survive in it.

Describe the motion shown in the lines
Bogdan [553]

Answer:

Solution

For figure (a)

During interval AB Velocity is +ve, so the particle is moving in +ve direction, but it is slowing down as acceleration (slope of v-7 curve) is negative.

During interval BC Particle remains at rest as the velocity is zero. Acceleration is also zero.

During interval CD Velocity is -ve, so the particle is moving in -ve direction and is speeding up as acceleration is also negative.

For figure (b),

During interval AB Particle is moving in +ve direction with constant velocity and acceleration is zero.

During interval BC Particle is moving in +ve direction as velocity is +ve, but it slows down until it comes to rest as acceleration is negative.

During interval CD Velocity is -ve so the particle is moving in -ve direction and is speeding up as acceleration is also negatived

Which factor is most likely to have a density-independent influence on population growth? question 6 options:?
Murrr4er [49]
The factor that is most likely to have a density-independent influence on population growth is Extreme weather conditions. 
Density-independent factors such as weather and climate, exert their influences on population size regardless of the population's density. Conversely, the effects of density-dependent factors intensify as the population increases in size.

During cpr, what is the ratio of chest compressions to rescue breaths in adults?
RoseWind [281]
During bag-mask ventilation, giving a breath just until you see the chest rise is recommended to minimize the risk of gastric inflation. The compression-to-ventilation ratio for 1-rescuer adult CPR is 30:2<span>. The compression-to-ventilation (or breaths) ratio for 2-rescuer child/infant CPR is </span>15:2<span>.</span>
