False a watershed is an area of land that contains a common set of streams and rivers that all drain into a single larger body of water
Answer:
The common characteristics of Archaebacteria known to date are these:
(1) the presence of characteristic tRNAs and ribosomal RNAs.
(2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.
(3) the occurrence of ether linked lipids built from phytanyl chains.
Slow reproduction process is a disadvantage of sexual reproduction. So option A is correct.
Sexual reproduction is much slower than asexual form of reproduction and the meiosis process is much longer and complex than mitosis. The process of sexual reproduction depends on the fertilization and zygote formation which are time consuming processes. This longer duration of reproduction process leads to lesser number of individuals in the population. In this case there may be instances of producing only one organism per year and if by chance no offspring is produced for certain number of years can lead to extinction of the species.
Answer:
The answer is B.
Explanation:
I don't have an explanation. Though I'm pretty sure that is the answer to your question.
Answer:
B. a plant cell in the process of cytokinesis
Explanation:
In plant, during the division of parent cell into daughter cells, cell wall becomes hindrance and does not let the inward pinching of membrane, so a cell plate is formed at the middle of the cell, with two nuclei on the either side of the cell plate. Cell plate is formed at the center where the previous metaphase or equatorial plate was present.
