An example for life for an animal and plant are that the both require foods to live. Animals hunt there own food but plants make there own due to photosynthesis. But they are similar because they both require food to continue living. There are many more characteristics but that is just one common one.

The answer is Neogene
Explanation:
It cannot be Cenozoic because that is an era. Not a period. Paleogene, Neogene, and Quaternary (our current period) are all periods within the Cenozoic Era (our current era). On the geologic time scale, there are Eras, Periods, and Epochs (and a few more classifications). Humans first appeared in the Miocene epoch which is an epoch in the Neogene period (in the Cenozoic era).
This is why the answer is Neogene.

Answer and Explanation:
Tracheophyte plants, also known as vascular plants, are those that possess a supportive tissue that can also conduct fluids -The Xileme- and another tissue that conducts nutritious elements produced by photosynthesis -The Phloem-. These plants have a root (basically underground), a stem (aerial), and leaves. All of them together form the corm. And the corm counts with these vascular tissues to which we referred before.
There are different types of Tracheophyte plants, some of them produce seeds to reproduce and disperse -Spermatophyta- and some others reproduce and disperse by spores -Pteridophyta-. This last seedless group corresponds to ferns and other similar plants.
Pteridophytes characterizes for having a sporophyte that has stems with leaves and a root. It also has primitive xylem composed by tracheids and phloem, both of them formed by vascular bundles located in a central cylinder.
Spores are its dispersion units and are responsible for colonizing new areas. They also constitute the resistance units under extremely unfavorable conditions.
Their life cycle is composed of the asexual phase (sporophytic phase) and the sexual phase (gametophytic).
- The <u>sporophyte</u>, the dominant asexual generation, it is a perennial and diploid structure. Its aerial part might disappear during unfavorable seasons, but it reappears during spring or summer. The sporophyte is in charge of asexual reproduction
- The<u> gametophyte</u>, instead, is and haploid structure, ephemeral and must be in the water for its survival, and for sexual reproduction to be successful. In the presence of water, masculine gametophyte -antherozoids- are released and they swim to the archegonium to meet the ovocell. Antherozoids can swim because they have flagella. After fertilization, a new sporophyte is produced.
Answer:
Damage to DNA can render a cell useless, or even harmful to an organism. Apoptosis, or programmed cell death, evolved as a rapid and irreversible process to efficiently eliminate dysfunctional cells. A hallmark of cancer is the ability of malignant cells to evade apoptosis.
