Answer:
C) they lack lignified vascular tissue. (
Since they do not have vascular tissues, they are not able to develop vertically like the trees we know.)
Explanation:
A)
Plants do not have "sperm". They have sporophytes or gametophytes.
B) No specific parasitic bacteria of bryophytes are known.
D) In fact, they have. Although they require water for their reproduction, some species of bryophytes are found in deserts.
E) Rhizoids are not weak, otherwise they would not have the ability to keep bryophytes attached (mosses).
A gamete would correctly be called a SEX CELL.
The cells from the male and female parents which combine to form zygote are called gametes. The male gamete is called sperm while the female gamete is called egg. Both sex cells combine together during fertilization to form the zygote.
So, there's five steps to the scientific method: Identifying the problem, forming a hypothesis, doing research and collecting background data, conducting the experiment, and finally coming to a conclusion. Arya already completed step one and two, because she sees a problem (the dry soil), and then comes up with a hypothesis, which is the water content in the soil in her yard is 2/3 lower due to the slope of her yard. Next, she's going to have to go and collect her data! This may include taking soil samples from her own yard and her other neighbors yard, and then measuring the slope of their yards ect. Then, she's going to take this information and put it into the experiment stage, and then she will come to her final conclusion!
Answer:
b
Explanation:
Evolutionary theory highlights the adaptive value of within-species variability. Optimal biological and behavioral strategies differ depending on the nature of the environmental context as well as the characteristics of the organism such as age, sex, health, or physical size.
