Answer:
They look like X's (X shape)
Explanation:
The X shape are replicated chromosomes and are called the sister chromatids.
Evidence for evolution, in other words evidence of common descent, include fossils, which have shown a (fairly) steady change in morphology over time for some species. An example would be horse hooves: we have fossils that show when they were still three toed, then two toed, then one toe in our present day horses. Another piece of evidence is vestigial organs. An example of vestigial organs is wings in some flightless birds, such as the kiwi. Their ancestors used it in order to fly across the marine barrier into New Zealand, but natural selection and random genetic drift made them quickly lose the ability to fly. Nonetheless, they still have their wings, however small. It can be assumed that eventually, their wings would be reduced to small stubs fused to other nearby bones, as has been observed in their cousins.
Answer:
For the difference of the two: Bacteria contain peptidoglycan in the cell wall; archaea do not. The cell membrane in bacteria is a lipid bilayer; in archaea, it can be a lipid bilayer or a monolayer. Bacteria contain fatty acids on the cell membrane, whereas archaea contain phytanyl.
B the organ that turns into the shell of the animals
Answer:
d) 1-2 reps, 3-5 sets
Explanation:
In training session there is always a progressive set, rep, and loading protocol which is needed to build-up maximum strength.
Now, the range that is set to achieve maximum power when using 55-85% of 1RM is 1-2 reps, 3-5 sets. This is so because most extreme power can happen somewhere getting ready to 55% and 85% of the 1 RM.
When a trainee choose let say for example, 1 repetition maximum (1 RM), to obtain the maximum power, its advisable to:
Cut that # in half
Add 1-2 rep
Perform 3–5 sets of this #
; and
Rest 1–2 minutes between sets.
