What does topography show?
Answers
Answer:
I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.
II. The shape of the land.
Explanation:
In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a topographic map is used to graphically describe this features.
A topographic map can be defined as an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of the Earth.
A topographic map is a two-dimensional model that uses contour lines to represent points of equal elevation above sea level such as mountains, hills, plains, valley etc.
The two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.
Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface.
Hence,a topography show two (2) main things and these includes;
I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.
II. The shape of the land.

Describe a control for the above experiment. The factor, the presence of starch (if the process of photosynthesis has taken place or not) needs to be left out. How would you do this?
Answers
During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:
transported to the growing parts of the plant for use in respiration
transformed into cellulose, proteins and oils
turned into starch for storage
Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.
Iodine solution is used to test leaves for the presence of starch. You need to:
heat a plant leaf in boiling water for 30 seconds (this kills the leaf, stopping any chemical reactions)
add the leaf to boiling ethanol in a water bath for a few minutes (the boiling ethanol dissolves the chlorophyll and removes the green colour from the leaf - it turns white so it is easy to see the change in colour)
wash with water to rehydrate and soften the leaf and spread onto a white tile
add iodine solution from a dropping pipette
After a few minutes, the parts of the leaf that contain starch turn the iodine from brown to blue/black.
Hope this helps :)

d. the beating collar cells form a current from osculum to pores; the food is engulfed by amoebocytes in the central cavity of the sponge.
e. water the moves gently through the sponge and the amoebocytes that engulf passing food.
Answers
Answer:
c. the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells.
Explanation:
Sponges contains the unique feeding system that should be with the animals. Rather of mouths they have the tiny pores that we called as the ostia displayed on the outer walls via water is drawn. Here cells in the sponge walls strainer the food from the water because the water is pumped via the body and the little mouth
So as per the given options, the option c is correct as the collar cells would create the current and the food should be absorbed by the collar cells
Mechanical weathering is more rapid in warm, wet climates.
true or false?
Answers
Answer:
false
Explanation:
In cold climates, water freezes and expands as a result, breaking rocks with sheer force. The smaller rocks or sediments are washed away by erosion.
During the warm wet season, rocks expand and contract. As a result, the rocks are weakened and eventually fracture.
Note that the rate of weathering depends on the types of rock and temperature change. Rocks in tropical climates experience the highest rate of weathering because of the combination of high heat and heavy rainfall.

This sea anemone and this ctenophora both have tentacles, which are body structures that help them catch food. However, sea anemone tentacles are short and can sting, while ctenophore tentacles are long for grabbing and cannot sting. What most likely explains why both species have tentacles and why the tentacles are different
Answers
Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.
Explanation:
most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,
Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.

time: 1.122 secondsrange: 10.693 mmaximum height: 1.543 mExplanation:
Given:
runner is launched at 30° angle to horizontal at 11 m/s
acceleration due to gravity is g = -9.8 m/s²
Find:
runner's hang time
runner's distance to the landing point
runner's maximum height
Solution:
The (horizontal, vertical) speed components will be ...
(11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)
The time of flight can be found from the height formula:
h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch
The time we're concerned with is the time when h(t)=0 and t>0.
0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)
The second factor is zero when ...
t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time
__
The distance to the landing point will be the product of horizontal speed and hang time:
d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing
__
The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...
h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.
