The size of stomata to check transpiration
Answer;
Advantages of sexual reproduction:
- It provides genetic variation.
Disadvantages of sexual reproduction:
- Not all mutations are passed on.
- It is time and energy consuming.
- The reproduction process is slow.
Sexual reproduction is a type of reproduction in which genetic information from two genders or sexes combine to produce a offspring. Both the gender produce gametes which fuse to form zygote which develops into an offspring.
There are several advantages and disadvantages associated with sexual reproduction as compared to the asexual reproduction.
The advantages are:
- It provides genetic diversity to the species.
- It naturally increases the levels of diseases resistance throughout the species.
- It can lead to the incorporation of evolutionary advancements in a population.
- It can give a rewarding experience specially in human beings as it releases dopamine in the brain.
- It also helps in improving health, growth of brain cells, relieving pain, can act as anti-depressant etc.
The disadvantages are:
- It is time and energy consuming process.
- Reproduction is uncertain as it is not a 100% successful method for producing offspring.
- Not all favorable variations or mutations are passed on to the next generation.
- Number of offspring produced is usually low.
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Explanation:
The oxygen within the leaf must be expelled to allow the to leaf sink, the level of oxygen within the leaf could correlate to the rate at which the leaf sinks or how far the leaf is able to sink if it is able to sink at all
The advantages of sexual reproduction:
•Produces genetic variation in the offspring
•The species can adapt to new environments due to variation, which gives them a survival advantage
•A disease is less likely to affect all the individuals in a population
