Answer:
The similarity between ferns and humans is that both go through meiosis and mitosis. But ferns are different because they have multicellular, free-living haploid and diploid forms. In humans, the haploid stage exists in the form of single cells—sperm and eggs. Only the diploid stage that begins with a zygote grows mitotically to form a multicellular, free-living human.
Explanation:
Humans and ferns are similar as both of these organisms fertilize to reproduce while differs in the haploid form of life which is present in the ferns and the male and female reproductive parts present in humans.
What is the life cycle of a fern?
The life cycle of fern includes the diploid fern which gives rise to the haploid spores that grows and form a gametophyte plant in which both the male and female reproductive systems are present. The male gamete undergoes fertilization with the female gamete to form a diploid spore (seed) which gives rise to the new fern plant.
Human’s reproductive cycle include diploid animals and the male and female genders which can be distinguished clearly. The male gamete-sperm fertilizes with the female gamete-egg to form the diploid zygote that gives rise to a new human.

Which explains why secondary succession generally occurs more rapidly in an area than does primary succession?
A) Average precipitation is higher
B) Moderate climatic conditions exist
C) Pioneer species are microscopic
D) Soil formation has already occurred
Answer:
Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

25. How do the excretory systems of animals that secrete uric acid differ from those of animals that excrete urine?
34. Explain why maintaining water balance is part of the process of excreting nitrogenous wastes.
thanks!!
Answer:
25.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.
34.The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. In providing these functions, excretion contributes to the body's homeostasis, the maintenance of constancy of the internal environment. When cells break down proteins, they produce nitrogenous wastes, such as urea

Compare the use of hormones as chemical messengers in plants and animals.
Both plants and animals use glands to produce and secrete hormones.
Many of a plant's hormones are secreted into the air, while many of an animal's hormones are secreted into the blood.
Many of a plant's hormones are secreted into intercellular fluid, while many of an animal's hormones are secreted into the blood.
Plants do not use hormones as chemical messengers, but animals do.
Many of a plant's hormones are secreted into intercellular fluid, while many of an animal's hormones are secreted into the blood.
Hormones are those substances which gives an organism the ability to respond to both internal and external stimuli which are necessary for their growth and maintenance.
Plant hormones are also known as plant growth substances which are produced in small amounts within the plant body (intercellular fluid).
They control growth and growth movements by accelerating or inhibiting cell division, elongation and differentiation.
Examples of plant hormones include auxins (produced at the apices of shoots) and gibberellins.
The animal hormones are secreted by endocrine glands directly into the blood stream. There are then transported to where ever they are needed.
Examples of animal hormones include:
