PCR multiplies the DNA in 25 to 75 cycles
Neko [114]3 years ago

This is the chain reaction in the name polymerase chain reaction. PCR is so efficient because it multiplies the DNA exponentially for each of the 25 to 75 cycles. A cycle takes only a minute or so and each new segment of DNA that is made can serve as a template for new ones.

Suppose the rate of plant growth on isle royale supports an equilibrium moose population of 850 moose in this scenario there are
lesya692 [45]

The population of moose will still be around 850 in 30 years.

<h3>What is carring capacity?</h3>

Carrying capacity is the number of individuals that an environment can support without significant negative impacts to the organism and its environment.

With that being said, the moose population size will be same or still 850 after 30 years. Rate of plant growth on isle Royale supported in equilibrium moose population of 850 moose and if there will more 200 mooses arrived then there will be no sufficient plants available to feed those additional mooses. This is the concept of carrying capacity. Carrying capacity is defined as the species average population size in particular habitat. Species population size is restricted by environmental factor like food, shelter, etc. If number of mooses will be increased in particular habitat and plants are limited ,then there will be strong competition between them, which results in survival of the fittest.

So when population size increases on Isle Royale,may be in beginning, for a while there will be sufficient plants to feed those additional 200 mooses, but after some time plant population will reduce and there will be not enough plants to feed all of the mooses. And if needs are not met, population will decreases which allows plants to grow in normal population to feed 850 mooses. So, after 30 years moose population size would be around 850 mooses.

Carrying capacity is the maximum number of individuals an environment can support for a long period of time. What might happen w
nignag [31]

Explanation:

A population's maximum number of individuals which may be supported by an environment or habitat. This occurs after the available resources have been exploited beyond their limit- i.e. the resources have been depleted at a faster rate than they have been renewed. At this stage, the population significantly decreases in size as some individuals die off due to scarcity and competition.

6. species Closely related of orchids never mate in the wild because they bloom at different times. This is an example of ______
Dimas [21]

Answer:

temporal reproductive isolation

Explanation:

The correct answer would be temporal reproductive isolation.

<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.

Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.

Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.

<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>
