What best explains why there's fewer secondary consumers than producers?
Answer:
because of inefficiency
Explanation:
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. ... Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.
Daughter cells formed by mitosis have exact copies of the parent cell's DNA. What process ensures that is possible?
Daughter cells formed by mitosis have exact copies of the parent cell's DNA. The anaphase process ensures that is possible.
What is mitosis?Cell division occurs during mitosis. All eukaryotic cells go through the process. There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
Prophase: This is mitosis's initial phase. At this point, the chromosomes begin to compress and the cell begins to break.
This is the second phase, or metaphase. The chromosomes align in the spindle fiber during this stage, and a checkpoint is also established.
Anaphase: At this time, the sister chromatids separate, align, and the chromosomes divide.
The final phase is known as the telophase. The nuclear membrane developed as the nucleus closed.
Therefore, the process that ensures the daughter cells formed by mitosis have exact copies of the parent cell is the anaphase.

1. At the freezing point, the particles in an object have no kinetic
energy.
2. On the Celsius temperature scale, there are no negative
numbers.
3. The more particles an object has at a given temperature, the
more thermal energy it has.
4. Object A is much larger than Object B, but both are made of
the same material. If both objects are at the same temperature, the thermal energy
of Object A is the same as the thermal energy of Object B.
5. When heat is absorbed by an object, the speed of the particles
in the object is unchanged.
Answer:
true
Explanation:
False. At the freezing point, the particles in an object have some kinetic energy.
False. On the Celsius temperature scale, there are negative numbers.
True. The more particles an object has at a given temperature, the more thermal energy it has.
False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
False. When heat is absorbed by an object, the speed of the particles in the object is changed.
Explanation:
The temperature is defined as the measure of hotness and coldness.It is measured in terms of degrees Celsius, Kelvins, degrees Fahrenheit.There are negative numbers on the Celsius temperature scale and Fahrenheits temperature scale but not on the Kelvin temperature scale.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature. The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.The object with more mass will have more particles and more will be the kinetic energy associated with the particles.When heat is added to an object to raise its temperature the kinetic energy of the particles increases. As kinetic energy is directly linked with speed or velocity.So from this, we can conclude that :
At the freezing point, the particles in an object have some kinetic energy.
On the Celsius temperature scale, there are negative numbers.
The more particles an object has at a given temperature, the more thermal energy it has.
Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
When heat is absorbed by an object, the speed of the particles in the object is changed.

Evolution is any change in the heritable traits within a
A. generation
B. population
C. individual
Answer:
B. population
Explanation:
CORRECT
Evolution is any change in the heritable traits within a population. Therefore, option (B) is correct.
What is evolution?Evolution is the process by which populations of organisms change over time through the gradual accumulation of genetic variations. It is the central concept of modern biology and provides a framework for understanding the diversity of life on Earth.
Evolution occurs through the mechanisms of natural selection, genetic drift, gene flow, and mutation. Over time, genetic variations that confer a survival advantage in a particular environment become more common in a population, while those that are detrimental or neutral are selected against.
This process can lead to the emergence of new species, as well as the extinction of others. The study of evolution has practical applications in fields such as medicine, agriculture, and conservation, and helps us understand our place in the natural world.

How do other organisms benefit from other biotic and abiotic things in tropical rainforest?
Answer:
All of the biotic factors are dependent upon the abiotic factors. ... Water, sunlight, air, and the soil (abiotic factors) create the conditions that allow rain forest vegetation (biotic factors) to live and grow. Organisms like monkeys, bats, and toucans eat the vegetation supported by the abiotic factors.
Explanation:
Biotic things are stuff like sunlight, air, dirt, etc. Plants and animals are abiotic. Abiotics benefit from biotics because they use the air, light, and dirt to function in everyday life.

Which molecules contain only carbon, hydrogen, and oxygen?
Select all that apply.
carbohydrates
glucose
proteins
O nucleic acids
[tex] \huge \purple{\tt{Answer:}} [/tex]
glucose
The molecule here that contains only carbon, hydrogen, and oxygen is Glucose. So the correct option is B.
What is glucose?Glucose is a monosaccharide or simple sugar. It is a kind of sugar found in honey and fruits. Glucose is the major sugar present in our body.
It is the main source of cellular energy utilized in the process of cellular respiration. Thus, it helps in proper cell functioning and metabolism.
Starch molecules are composed of various monomers of glucose. They are the polysaccharides of glucose. The structural formula for glucose is C₆H₁₂O₆. This means that glucose is only composed of carbon hydrogen and oxygen atoms.
Glucose is a type of Carbohydrate but there are other kinds of carbohydrates that contain elements like nitrogen and sulfur. Proteins and nucleic acids also contain other elements like phosphate, nitrogen, and sulfur.
Thus only glucose is composed of oxygen, carbon, and hydrogen.
Therefore the correct option is B.

Which of the following would change the allele frequencies of a population?
A)Lack of mutation in the DNA
B)Mating is random with no selection occurring
C)A population on an island remains isolated and no one leaves or moves on the island
D) All of the answer choices would change allele frequencies of a population.
Answer: option B.
B)Mating is random with no selection occurring
Explanation:
This will cause change in allele frequency because it's a genetic drift which is the change in the frequency gene variant that is common in a population due to random sampling or random mating. When this occur it lead to a change in percentage or incidence of gene variant in a population since there is random sampling without any selection.
Mating is random with no selection occurring, which would change the allele frequencies of a population.
What would increase the allele frequency in a population?Natural selection can drive microevolution, or a difference in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations.
Thus, option"B" mating is random with no selection occurring.
