Mango tree > Caterpillar > Sparrow
The first level in a food chain should be a primary producer which is the mango tree.
The second level in a food chain should be Primary consumer which is the caterpillar.
The third level in a food chain should be the secondary consumer which is the sparrow.
A food chain always starts from left to right. This from the primary producer then to the other levels. np

What is meant by the term "density"? Please provide an example of how
density is determined in air masses.
Answer:
1) density "the degree of compactness of a substance."
2) air masses "More dense, or “heavier” air will slow down objects moving through it more because the object has to, in effect, shove aside more or heavier molecules. Such air resistance is called “drag,” which increases with air density."

what is unequal reproductive success
Unequal reproductive success, also known as differential reproductive success, is a fundamental concept in the theory of evolution proposed by Charles Darwin.
It refers to the variation in the number of offspring produced by individuals within a population based on their inherited traits and adaptations.
Individuals possessing advantageous traits that better suit their environment are more likely to survive, reproduce, and pass on these favorable traits to their offspring.
On the other hand, individuals with less favorable traits may have lower reproductive success.
Over successive generations, the frequency of advantageous traits increases in the population, leading to the process of natural selection and the gradual evolution of species to better adapt to their changing environments.

c. in seperate gametes
d. meiosis II
e. in one gamete
f. law of Segregation
g. depend on
h. independent of
i. law of Independent Assortment
j. meiosis I
1. _____is illustrated by the behavior of two pairs of homologs during_____. The alignment of one homologous pair is_____the alignment of other pairs. 2. _____is illustrated in_____when homologs separate. Alternate alleles of a gene found on homologs segregate from each other and end up_____.
Answer:
1. law of Independent Assortment; metaphase I; independent of.
2. law of Segregation; meiosis I; in separate gametes.
Explanation:
Between 1856 and 1863, Gregor Mendel developed a series of mating experiments using pea plants, which enabled the discovery of some basic principles of inheritance. These principles/laws are stated as:
1) Law of segregation: this principle states that the inheritance pattern of phenotypic traits is characterized by the presence of a gene pair and each gamete carries only one allele for each gene pair so offspring inherit one gene variant (allele) from each parent
2) Law of independent assortment: this principle states that the genes responsible for the inheritance pattern of different traits are independently sorted from one another and thereby different traits are independent one from another.
3) Law of dominance: this principle states that the dominant allele will always be expressed in heterozygous individuals (this law is only applicable in cases of complete dominance).
Who does the mesosphere share a boundary with?
Answer:
The boundaries between layers in the atmosphere have special names.
Explanation:
The mesopause is the boundary between the mesosphere and the thermosphere above it.
The stratopause is the boundary between the mesosphere and the stratosphere below it. Scientists know less about the mesosphere than about other layers of the atmosphere.

i)Which one of the following substances have sour test.a) acid b)base c) salt d) all of these
Answer:
a) acid
Explanation:
Acid is a chemical substance that is capable of donating protons (H+) when in an aqueous solution. This property makes a substance an acid, although the ability to donate completely or partially distinguishes a strong and weak acid.
One of the characteristics of acids is their SOUR TASTE. This characteristic sour taste is attributed to the hydrogen concentrations present in acidic foods or substances e.g unripe fruits.

Answer:
C!!
Explanation:
It's not B because it's located in the great plains. Not D because in 50 years, 70% of the aquifer will be gone. Not A because water use isn't regulated.
Ogallala Aquifer is the rock holding the groundwater in the Great Plains of America. The Ogallala Aquifer is running out of water. Thus, option C is correct.
What is Ogallala Aquifer?Ogallala Aquifer is an underground layer of water that is held by the rocks, pebbles, and gravel that make the water well above the surface. It is not beneath the East Coast but is situated on the Great Plains of the United States.
It has been reported that the water usage of the Ogallala Aquifer is not regulated and hence it does not have enough water to last up to 6,000 years. At approx 70%, the water of the aquifer will be soon gone resulting in the deprivation of the water.
Therefore, option C. the Ogallala Aquifer is running out of water is correct.
