There is more water that enters the water cycle from the tropical region than from the desert regions.
What is the water cycle?Water does move from one point to the other in the eco system and this crosses all of the spheres of life. The water cycle involves the evaporation of water both from the surface waters and from plants and the condensation of the same to fall back to the earth as rain.
Given the fact that there is abundant rain fall in the topics than we have in the desert, there is a greater availability of water in the tropical region than in the desert regions. This makes it only natural that we expect that more water would evaporate into the water cycle from the tropical region than it does from the desert regions.
Thus means that the region that would ultimately contribute to the water cycle is the tropical region.

Which of the following is the best example of an adaptation that helps an organism survive in its environment?A. Green coloring on a lizard living one red and brown rocksB. A thick coat of fur on an animal that lives in the desertC. A long root system in a desert plantD. Thin, delicate leaves on a plant that lives in the tundra
An adaptation that helps an organism survive in its environment would be an adaptation that helps this organism get food/water, hide from predators, not loose too many water or nutrients, etc.
A green lizard living in red and brow rocks would cause a great contrast between the colors, putting the lizard in evidence and making it easier for predators to find it. Therefore, A is incorrect.
The adapted leaves of plant from the tundra will be small and waxy, but not too thin as it will try to keep more water inside it than being lost in transpiration. Therefore, D is also incorrect.
An animal that lives in the desert can't have a thick coat of fur because it will make the animal be super heated, causing loss of water that is so important to keep in a desert. So B is incorrect too.
In deserts that are no water easily available, so a plant can have a long root system in order to get water from deep below the surface of the ground. Therefore, the correct answer is C. A long root system in a desert plant
The gray wolf at one point almost caused the extinction of a certain species of rabbits in the Northwest. The initial abundance of rabbits allowed the gray wolves to hunt easily and eat many rabbits. Eventually the rabbit population began to decrease, resulting in a change in the wolf population.
1. The predator in this scenario is Gray Wolf while the prey is the Rabbit population.
2. Since, the rabbit population is the food of gray wolves, the depletion of rabbits will also increase the intraspecific competition among gray wolfs. this will further lead to an imbalance in the ecosystem and the gray wolf population will also decrease.
3. Decreasing the population of gray wolves in the area will automatically reduce the killing of rabbits. In this way, a balance will be maintained. Therefore the extinction of no species will occur in that area.

A cross-country skier travels 5Km due North, makes a right-angled turn, and travels a further 12Km due East. (a) If the distance is covered in 51 min, what is the skier average speed in Km/h? (b) What is the magnitude of the skier's average velocity in Km/h?
The skier's average speed in Km/h is 20 ms⁻¹.
The average speed of the object is multiplied by the time traveled to discover the displacement. The equation x = ½( v + u)t may be manipulated, as proven below, to locate any one of the 4 values if the other 3 are regarded. Speed is the directional speed of an object in motion as an indication of its rate of change in function as observed from a selected body of reference and as measured by means of a particular standard of time.
calculation:-
Average speed = total distance / total time taken
= 5 + 12 / 51 min
= (17 / 51)× 60 hr
= 20 ms⁻¹
total displacement = [tex]\sqrt {5^{2} +12^{2}[/tex]
= 13 m North - East
Magnitude of average velocity = (13/51) x 60
= 15.29 ms⁻¹
The velocity is the time fee at which an item is moving along a direction, even as the pace is the rate and route of an item's motion. speed is the speed at which something moves in a particular route. An example as the speed of an automobile touring north on a toll road, or the velocity a rocket travels after launching. In a scalar way, the absolute price magnitude of the velocity vector is continually the rate of the motion.

In guinea pigs the coat may be rough or smooth. Certain rough-coated guinea pigs when crossed with smooth-coated ones produce all rough- coated offspring. Other rough-coated guinea pigs when crossed with smooth-coated ones produce equal numbers of rough-coated and smooth-coated offspring. Smooth-coated guinea pigs crossed together always produce smooth-coated offspring. Explain these results. Write the genotypes for all animals concerned in the crosses.
The result for this will be:
smooth in 1:1 proportion. 8 rough: 7 smooth is near 1:1.
Smooth-covered parent must be rr. The rough covered parent is either RR or Rr.
In the event that the parent is RR, RR X rr ought to give all Rr progeny in F1s, or as such,

In the event that the parent is Rr, Rr X or ought to give Rr: rr descendants in 1:1 proportion or unpleasant:

River is a freshwater biome is characterized by fast-flowing water that can originate from underground springs or runoff, which carries sediment and organic material. Because of gravity, water flows from a higher height to a lower elevation to produce rivers.
Freshwater biomes include lakes, ponds, rivers, streams, and wetlands; they vary in depth, water movement, and other abiotic elements. When rain falls on land, it either seeps into the ground or transforms into runoff, which travels to the sea by flowing downhill into rivers and lakes as freshwater biomes.
A river is a significant, un-manmade stream of moving freshwater. On practically every type of land and on every continent, rivers can be found. Some flow continuously throughout the year. Others flow sporadically or during wet years.

The statement 'infer the DNA base sequence from the amino acid sequence of insulin' describes a step in the process scientists used to find the gene that makes human insulin (Option A).
What is the insulin gene?The insulin gene encodes for insulin which is a key hormone secreted by the pancreas in order to metabolize glucose and thus maintain this hormone (insulin) in normal levels in the blood.
The insulin gene sequence can be inferred by observing the sequence of amino acids which indicates the most likely codons that may be used to encode this peptide hormone in natural conditions (i.e. within the human body)
Therefore, with this data, we can see that the insulin gene is composed of a linear nucleotide sequence which can be inferred by observing the natural order of codons in mRNA and or the order of amino acids in the insulin hormone.

a. As the population becomes larger, it grows more slowly.
b. When the population reaches carrying capacity, it stops growing (
c. the population grows at a steady rate
d. As the population becomes larger, it grows more and more rapidly
Answer:
- When the population reaches carrying capacity, it stops growing.
- As the population approaches carrying capacity, it grows more slowly.
Logistic growth is the growth showing that the population grows in a curve where it is rapid first and reach the slow rate later on. The correct answer is option A.
What is population ?It is defined a s the mass of people living together who share the features in similarities in the choice of adaptation and habitat in which they reside in.
As the population sizes increases there is scarcity in the resources on which the people live on along with the kind of adaptation and habitat in which they are living.
The slower growth rate means the population is in a big number with the shortage of food this is why the logistic growth curve shows that there is a big increase in the population rate first but later on when the resources number gets slowed down then at that time it will show low population growth rate.
