Could you explain the roles and relationships among producers, consumers, and decomposers, and identify the distinguished characteristics of several common relationships among organisms in an ecosystem near you?
Answer:
A consumer may also eat other consumers as food. When producers and consumers die, the Decomposer will come along to decompose (break down) the bodies of the dead producers and consumers into smaller chemicals - in short treating them as a food source
Explanation:
Your welcome have a good day :)
The producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.
What is an Ecosystem?The interaction between the organisms of different species plays their role in a systematic way as decided by natural selection, which is known as the Ecosystem.
Producers use light energy and inorganic matter to produce food. They are always present first in the ecosystem. Consumers take energy from plants known as herbivores, and also from herbivores known as Carnivores. Decomposers convert dead organic matter into inorganic matter. This inorganic matter helps producers perform metabolic activities. And finally, this cycle goes on.
Therefore, the producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.

define atomic number and mass number – describe how they differ
Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.

If an organism inherits 1 dominant allele from one parent and 1 recessive allele from the other parent, what is it called?
Answer:
heterozygous
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. Genotypes are described as heterozygous if the two alleles differ.

Which statements are true?
1 and 2

2.4 and 5
3.4 and 5
Answer: 2, 4 and 5.
Explanation:
Human system are made of various organs which in turn are made up of various tissues which in turn are made up of various cells. Cells are therefore much more numerous than systems.
As already mentioned, organs are made up of tissues which are made up of cells so statement 4 is right.
As systems are made up of various organs working together, they are more complex than the individual organs. For instance, the Muscular system is more complex than the triceps or bicep muscles.

A liver cell has a volume of 5000 μm3. Its total membrane area, including the inner membranes lining organelles as well as the cell membrane, is 110,000 μm2. A cell in the pancreas that manufactures digestive enzymes has a volume of 1000 μm3 and a total membrane area of 13,000 μm2. Which cell is probably more efficient in carrying out activities that require extensive membrane surfaces? Why?
Answer:
The liver cell, since it has a higher surface to volume ratio will be more efficient in carrying out activities that require extensive membrane surfaces such as solute transport.
Explanation:
The cell surface area to volume ratio is important in order to determine the efficiency of the cell in carrying out its metabolic activities. The surface area of a cell is bounded by the cell membrane whose function in addition to many others is to let nutrients into the cell and let waste out of the cell. The rate of activity of a cell depends on its volume. The larger the volume the more the active the cell is. Since volume increases much more when compared to area, the ratio of the surface area of a cell to its volume becomes smaller with increase in volume of the cell.
Considering the liver cell and the pancreas cell in the question, the cell's surface area to volume ratio is given as follows:
Liver cell: volume = 5000 μm³; area = 110000 μm²
surface area to volume ratio = 110000 / 5000 = 22 : 1
Pancreas cell : volume = 1000 μm³ ; area = 13000 μm²
Surface area to volume ratio =13000 / 1000 = 13 : 1
The liver cell, since it has a higher surface to volume ratio will be more efficient in carrying out activities that require extensive membrane surfaces such as solute transport.

Each individual occupied a different ecological niche and so some were unaffected.
Genetic variation in the population allowed some weeds to survive.
The spray caused some individuals to mutate, and they were able to survive and
reproduce.
Answer:
Genetic variation in the population allowed some weeds to survive
Explanation:
Herbicides are substances that are used to destroy unwanted plants. Herbicides are also called weed killers. An herbicide killed 99% of a weed population.
Some weeds were not able to survive as genetic variation in the population allowed some weeds to survive.

Analogy and homology are important concepts used in comparing species. Traits are homologous if they are derived, evolutionarily and developmentally, from the same source structure. Traits are analogous if they have similar functions but are derived, evolutionarily and developmentally, from different source structures. A classic example of analogous structures is insect wings and bat wings. Which of the following pairs of structures are analogous and which are homologous?
a. Dorsal fins of porpoise and a salmon
b. Flippers of porpoise and pectoral fins (front fins) of salmon
c. Joined leg of ladybird beetle and a robin
d. Rhesus monkey's tail and human's coccyx
e. Bright red bracts of poinsettia and green leaves of rose
f. Red bracts on a poinsettia and red petals on rose
Answer:
a. analogous
b. homologous
c. analogous
d. homologous
e. homologous
f. homologous
Explanation:
a. Analogous. Porpoises are mammals while salmon are fish. In this case, fins are analogous structures that evolved separately in both groups.
b. Homologous. Pectoral fins evolved from the forearms of tetrapods, and early tetrapods evolved from fish.
c. Analogous. These structures evolved independently through convergent evolution in both groups.
d. Homologous. They are homologous structures that were inherited from a common ancestor (primates).
e. Homologous. Bright red bracts (modified leaves) of poinsettia and green leaves of rose share a common ancestor (i.e., angiosperms).
f. Homologous. They are homologous structures that were inherited from a common ancestor (i.e., angiosperms).
