What is a similarity between a tulip and a crocodile? A function of both of their outer coverings is to reduce water loss. In both the tulip and crocodile the male reproductive organ is the testes. The tulip and crocodile both have internal skeletons that support them. The outer coverings of the tulip and crocodile both protect the organism.
Answer:
A function of both of their outer coverings is to reduce water loss
Explanation:
Crocodile and Tulips are both distinct species of organisms. Crocodile belongs to Kingdom Animalia while Tulips belong to Kingdom Plantae. However, despite their elaborate differences, they do have one feature in common, which is the function their outer covering performs.
Tulips are temperate plants I.e. like cold regions, hence, their outer covering functions to prevent excessive loss of water. On the other hand, the scaly skin of the crocodiles help them against water loss. This is common between the two different species.
________ is a process that creates genetic variety in cells. (2 points)
Cell fission
Meiosis
Mitosis
Asexual reproduction
Answer:
B
Explanation:
I believe it is meiosis because there are two parts in which it helps to increase genetic variety. In prophase 1, the genes cross over, which increases the variety. Also, the chromosomes are assigned randomly in Metaphase 1.

Limestone is a rock formed from calcite. Calcite can be easily dissolved by acids. Marble is a rock formed from limestone. Therefore, what can be said about marble? Question 4 options: Marble is a metamorphic rock Marble can be dissolved by acids Marble can be dissolved by acids All of these are correct
Answer:
All of these are correct
Explanation:
According to the question, marble is a rock formed from limestone, which in turn is also formed from Calcite. This shows that marble is a kind of metamorphic rock because a metamorphic rock is any rock that is formed by the alteration of other rocks caused by heat, pressure or chemicals etc. These changes that occurs in the previously existing rocks are called METAMORPHOSIS.
Hence, since marble is formed from limestone, it concludes that marble is a metamorphosed rock formed from a previously existing limestone rock. Also, since Calcite, a precursor of limestone that marble is formed from can be degraded by acids, both limestone and marble which are formed from it will also be dissolvable by acids.

In the phosphorous cycle, phosphorous enters the food chain when
A: it is in atom form
B: it is in the form of phosphate and bound in solids
C: it is the form of phosphate ions and dissolved in water
D: it is exposed to the air during weathering
Answer:
The correct answer is option C.
Explanation:
The biogeographical cycle that tells about the movement of the phosphorous in the different spheres such as the lithosphere, geosphere, biosphere, and hydrosphere known as the phosphorous cycle.
In the soil and sediments, the phosphorus is present in the form of ions and dissolved in water, which is move through the roots to the plant and enters in the food chain and biosphere.
Thus, the correct answer is - option C.
Which type of geologic event has to occur to create an angular unconformity
Answer:
folding or tilting of rock layer
hope this answer correct (^^)
The type of geologic event that has to occur to create an angular unconformity is the folding or tilting of rock layers. The correct option is 3.
What is an angular unconformity?An erosional surface that truncates older, tilted sedimentary layers and is covered by younger layers that are oriented parallel to the unconformity is known as an angular unconformity.
Angular unconformity typically occurs when sedimentary rock layers are deposited on top of one another and inclined, with the upper layer being younger than the lower layer. The unconformity might be thought of as the time when there were no preserved sediments in the area.
Tilting of rocks can take many different forms, including forcing the rock upward or folding sedimentary rock.
Therefore, the correct option is 3.) folding or tilting of rock layers.

How does the nervous system work with the circulatory system
Answer:
look at the explanation
Explanation:
the circulatory system also known as the heart, lungs, brain and blood stream are all connected to the brains by nerves, sending small electric currents (commands) to the organs telling them what to do. when the nerves are stimulated, they send signals to the brain giving it information.
Please help me, and only provide with the given answers so I am not confused. The curve on the left shows the height of a population of penguins. The curve on the right shows the population five years later. What has happened to this population? (Available answers are in photo) Will mark best answer BRAINLIEST
Explanation:
DIRECTIONAL SELECTION!!!!!!!!!!!!!!!!!!
The population of penguins has gone through the directional selection.
What is directional selection?It is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes.
This causes the allele frequency to shift over time in the direction of that extreme advantageous phenotype.
How these two graphs shows directional selection?On each graph, the X-axis variable is the type of phenotypic trait (here height) and on the y- axis variable is the number of penguins.
Left graph shows the population before directional selection and right graph shows the population after directional selection.
Here height of the penguins reduces and favored over time due to directional selection.

Plants absorb sunlight through Photosynthesis. Which characteristic of life is this an
example of?
A. Obtains and uses energy
B. Responds to stimuli
C. Grows and develops
D. Homeostasis
Answer:
A. Obtains and uses energy
The characteristic of life shown here is plants obtain and use energy.
What is photosynthesis?By using the energy from sunlight, plants, some bacteria, and some protozoa make sugar, which cellular respiration then transforms into ATP, the "fuel" that all living things use. The green pigment chlorophyll is responsible for the transformation of inefficient solar energy into useful chemical energy. The photosynthetic process makes use of water and emits the oxygen that is vitally necessary for our continued existence.The overall reaction of photosynthesis is:6H₂O + 6CO₂ + light energy → C₆H₁₂O₆+ 6O₂

Which of the following statements describes ways cellulose and starch are similar to and different from each other?
Explanation:
Similarities
Both starches and glycogen are polymers formed from sugar molecules called glucose. Each independent molecule of glucose has the formula C6H12O, and joining these subunits together in a certain way forms the long chains that make up glycogen and starch.
Sucrose, glucose and starch are related because they're all forms of carbohydrate.
Differences
Starch is formed from alpha glucose, while cellulose is made of beta glucose. The difference in the linkages lends to differences in 3-D structure and function. Starch can be straight or branched and is used as energy storage for plants because it can form compact structures and is easily broken down.
Which one of the following statements about the troposphere is
true?
Select one:
a. The troposphere is the atmospheric layer farthest from
the earth's surface.
b. The tropospheric gases move because of convection
currents.
c. The temperature in the troposphere ranges from 100° C
to -150° C.
d. The outer boundary of the troposphere is called the
stratopause.
e. Weather does not occur in the troposphere.
Answer:
B. The tropospheric gases move becuase of convection currents.
Explanation:
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. In the Northern and Southern hemispheres, air rises along the equator and subpolar ( latitude about 50 to about 70 north and south ) climatic regions and sinks in the polar and subtropical regions. Air is deflected by the Earth's rotation as it moves between the poles and equator, creating belts of surface winds moving from east to west ( easterly winds ) in tropical and polar regions, the winds moving from west to east ( westerly winds ) in the middle latitudes. This global circulation is disrupted by the circular wind patterns of migrating high and low air pressure areas, plus locally abrupt changes in wind speed and direction known as turbulence.
