The probability that these deserts plants will reproduce depends on the favorable environmental conditions affecting each seed group.
What are seeds?Seeds are reproductive parts of the plant containing the embryo which will develop into the new plant under favorable environmental conditions.
Xerophytes or desert plants are plants which grow where there is limited water.
In order to adapt to these conditions, some desert plants produce groups of seeds where only a small portion of the group germinates each year.
Therefore, the probability that deserts plants will reproduce depends on the favorable environmental conditions.

Explain why natural selection does not operate on characteristics which affect fitness but are not heritable.
Answer:
Natural selection can only work on heritable traits. Acquired traits are not heritable and are not subject to natural selection. Environmental factors are variable. A trait that is beneficial in one place or time may be detrimental in another place or time.
Define the word ubiquitous, and provide examples showing why this is an appropriate term to use when describing microbes.

Use the data and what you have learned about evolution to explain how mutation is a random process, but natural selection is not random.
The data are not found here, but evolution means 'descendence with modification', which may occur due to natural selection and mutations.
What is evolution?Evolution is descendence with modification, which generally is caused by a process called natural selection.
Natural selection 'selects' the most adaptive variants in the population, which occurs due to the emergence of mutations.
A mutation is any genetic change in the nucleotide sequence of the genome of an individual.

How does primary and secondary succession affect ecosystems? Give examples
Answer:
Explanation:
Primary succession makes an ecosystem virtually start all over. For example a nuclear explosion wipes out anything and everything in its path. This makes the exosystem start all over and rebuild itself. The secondary succession will only partially make the escosystem restart. For example a forest fire may wipe out some trees however there is still soil avalible for the ecosystem to grow back more easily

Choose all correct answers.
The phloem moves the food made in the shoots to all the other parts of the plant.
Vascular plants have leaves that absorb the water and minerals from the air.
The shoots are where the plant makes its food.
Hollow tubes called xylem carry the water and minerals up through the plant to the shoots.
Water and minerals are transported and used in vascular plants through :
A) Phloem moves the food made in the shoots to all the other parts of the plant D) Hollow tubes called xylem carry the water and minerals up through the plant to the shoots C) The shoots are where the plant makes its foodTransportation in Vascular plantsIn vascular plants the root hairs in the root take up water and minerals from the soil and this water and mineral is transported to the shoot and leaves of the plants through a tissue known as Xylem.
