Question

Determine whether the statements are true or false

1. The alternation of generations life cycle in protists and plants is a homology.

2. Bacteria flagella and euglenid flagella are homologous structures.

Answer #1

(1) In plants and protists, the reproductive cycles are comprised of the sporophytic and gametophytic generation which occur in a cyclic manner. There are certain traits that are homologous among these phylogenetically close relatives/taxa. So the given statement is true.

(2) The bacterial flagella and euglenid flagella are
non-homologous structures because their structure is totally
different. The bacterial flagella move by rotation while that of
*Euglena* by bending motion. So the given statement is
false.

Compare the life cycle of a human to the life cycle of a plant
(alternation of generations).
Name 2 similarities (2pts) and 3 differences (3pts). Use the
following format:
similarity 1:
similarity 2:
difference 1:
difference 2:
difference 3:

a sporophyte plant? Of the spores?

Determine whether the following statements are true or
false. If the statement is false, then explain why the statement is
false or rewrite the statement so that it is true.
If a scatterplot shows a linear association
between two numerical variables, then a correlation coefficient
that is close to 1 indicates a strong positive trend and a
correlation coefficient that is close to 0 indicates a strong
negative trend.

the
disease cycle and pathogen life cycle are the same thing. true or
false ?

Which of the statements about the life cycle of flowering plants
is false?
the haploid gametophyte produces gametes by mitosis
two sperm fertilize an egg to produce a zygote
the diploid sporophyte produces spores by meiosis
microspores and megaspores go through mitosis to produce
gametophytes
sporophytes are much larger than gametophytes

2) Determine whether the following statements are true
or false regarding the actions at the hip and knees as an
individual begins to elevate himself from a squatting to a standing
position. Justify your answer.
a) The iliopsoas muscle is moving from a “more elongated” to a
“more shortened” position. True or False? Why?
b) The gluteus maximus is concentrically active. True or False?
Why?
c) The hamstrings are likely inactive throughout this portion of
the movement. True or False?...

True or False? Circle whether the following statements are true
or false. Explanations are optional. (a) If f(x) is continuous on
[1, 2], then f(x) attains an absolute maximum on [1, 2]. TRUE FALSE
(b) If f(x) has a local maximum or a local minimum at x = 1, and f
′ (1) exists, then f ′ (1) = 0. TRUE FALSE (c) If f ′ (1) = 0, then
(1, f(1)) is a local maximum or a local minimum...

5. Determine whether the following statements are TRUE or FALSE.
If the statement is TRUE, then explain your reasoning. If the
statement is FALSE, then provide a counter-example. a) The
amplitude of f(x)=−2cos(X- π/2) is -2 b) The period of
g(x)=3tan(π/4 – 3x/4) is 4π/3.
. c) If limx→a f (x) does not
exist, and limx→a g(x) does not exist, then limx→a (f (x) + g(x))
does not exist. Hint: Perhaps consider the case where f and g are
piece-wise...
