B)Meiosis in the sporophyte would cease and the reproductive cycle would stop.
C)The flagellated sperm would not be able to swim to the eggs for fertilization.
D) The flagellated sperm and eggs would go dormant until water was available.

2. Which of the following is true of conifers?
A)The sporophytes grow directly from the gametophyte B)The gametophytes grow directly from the sporophyte C) The spores release from the male cones D)The spores release from the gametophyte

Answers

Answer 1

Answer: For the first question, the answer would be B, that the meiosis in the sporophyte would cease and the reproductive cycle would stop in a drought. This is because many die off in a drought so reproducing is not as common.
Secondly, the next answer would be D, that the spores release from the gametophyte. This is because only females reproduce in these cases.

A circle has a circumference of 615.44615. point, 44 units. What is the radius of the circle?

Answers

Answer:

The radius is 98

Step-by-step explanation:

The circumference of a circle is the distance around the edge of the circle. To find the circumference, we use the formula C = 2πr. You have the circumference so substitute C = 615.44. Then solve for r.

C = 2πr

615.44 = 2πr

98 = r

Answer: 98 units

Does the following graph represent a function?

Answers

Step-by-step explanation:

no.

in a function every x-value has exactly one associated y- value.

but this is clearly violated for x between about -4.5 and -3.5, where every x-value has 3 different associated y-values.

e.g. at x = -3, we get y = 0.5, -2 and -4.25.

Evaluate if x=13.2 and y=4.3 -x-2y

Answers

Lets substitute for each variable, then solve:-

x = 13.2
y = 4.3

x = 13.2
-13.2 - 2y

y = 4.3
-x - 2 · 4.3

Lets solve:-

-13.2 - 2 × 4.3
-13.2 - (2 × 4.3)
-13.2 - 8.6
-21.8

So, when x = 13.2 and y = 4.3, -x - 2y = -21.8
