On a construction site, a worker moves some debris and a bulldozer moves a different pile of debris Which of these best explains how the worker and the bulldozer are alike?
Choose the correct answer
Their physical properties are similar
They are both systems that are performing similar functions
They both use the same kind of fuel to provide them with energy
O They have control centers that are made from the same components
Answer:
The correct answer is - they are both systems that are performing similar functions.
Explanation:
In the given question there are two different entities that do a similar kind of work or perform similar functions, however, the systems are different as one system involves the manpower of a worker whereas the other system involves the high power of a bulldozer.
The work is similar but the amount of the work varies as manual work done by a worker is less in comparison to the bulldozer.

What chemical bond is responsible for the existence of the sugar-phosphate backbone of DNA
Answer:
Phosphodiester bonds
Explanation:
Answer:
The answer is phosphodiester bond.
Explanation:
The sugar phosphate backbone is an important stuctural component of DNA. It consists of 5-carbon deoxyribose sugars and phosphate groups. These sugars are linked together by a phosphodiester bond, between carbon 4 of their chain, and a CH2 group that is attached to a phosphate
where do inherited traits come from and where do acquired traits come from (2 answers) ANSWER GETS BRAINLIEST!!!
Answer:
Inherited traits come from family members and are in your dna and Aquired traits you learn so are from other people.
Explanation:
Answer:
parent to offspring and during life
Explanation:
1. An inherited trait is one that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.
2.Acquired traits develop during life (organism is not born with it) . Animals learn these when they interact with environment. It is not in your DNA. It will not be passed on to next generation.
What is gel electrophoresis? Explain how the length of base pairs flow through the gel.
Answer:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.

List the layers of the Earth in order from least dense to most dense.
Answer:
Crust, mantle, outer core, and inner core
Explanation:

The layers of the Earth from the most dense to the least dense are:
Inner CoreOuter CoreLower MantleUpper MantleCrustDensity is how much mass an object has for each unit of volume. This just means how much space something takes up compared to the amount of matter that it has. When something has a lot of mass compressed into a comparatively small space, we can say that object has a high density or that it is very dense.
The Core of the Earth is divided into an inner core which is the densest, and a slightly less dense outer core. Both of these are made of iron, nickel, sulfur, and oxygen. The mantle is also divided into two parts, an Upper and a much thicker Lower Mantle. The Lower mantle is denser than the upper mantle. These layers are made of silicate rock. The most superficial and least dense layer of the Earth is the Crust.
Therefore the layers of the Earth from most to least dense are the Inner Core, Outer Core, Lower Mantle, Upper Mantle, and Crust.

Two students completed an experiment to determine if pesticide use at local farms was causing fish kills in a local pond. The steps of the experiment are listed below. Select one location to collect water samples in the pond. Collect a 5-mL water sample at 8 am for two days. Measure the amount of pesticide present in each sample using the same measurement tools. After analyzing their data, the students conclude that pesticide runoff from farms is not causing the fish to die in the pond. Which of these statements best describes why their conclusion is not reliable? The pesticide measurements were the dependent variable. The samples were collected at different times. The samples were only collected for two days. The time of sample collection was not an independent variable.
Answer:
The pesticide measurements were the dependent variable
Explanation:
According to this question, an experiment to determine if pesticide used at local farms was causing fish kills in a local pond was conducted by two students. They followed the following steps:
- Select one location to collect water samples in the pond.
- Collect a 5-mL water sample at 8 am for two days.
- Measure the amount of pesticide present in each sample using the same measurement tools
However, after analyzing the data, they concluded that "runoff from farms is not causing the fish to die in the pond". The students' conclusion is not reliable because THE PESTICIDE MEASUREMENTS WERE THE DEPENDENT VARIABLE.
Note that, the dependent variable in an experiment is the measured variable while the independent variable is the manipulated variable. In this case, the students ought to measure the death RATE OF FISH KILLS as the dependent variable instead. The PESTICIDE is the independent variable of the experiment not dependent variable. This was the reason for the unreliability of the conclusion.
predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein
Full Question Attached
Answer:
The substance would be less likely to enter the cell by active transport or might enter more slowly
Explanation:
The information in the question suggests substance L is moving into the cell by active transport. We can tell this because the concentration of substance L inside the cell is 120 mM. However, the substance is still entering the cell from a lower to a high concentration, against its concentration gradient. This requires energy and is therefore active transport.
If there was a large protein attached, the active transport machinery might not be able to move substance L at the same rate. The rate it enters the cell might slow down, or it might stop all together. It might need to enter via another mechanism, such as endocytosis.

what else is needed to make glycine (amino acid) from a molecule of glucose? Where do you think that comes from
Answer:
certain amino acids are made of different things but heres overall carbon hydrogen oxygen and nitrogen
Explanation:
Glycine is a naturally occurring/formed amino acid found in humans, the difference between glycine and other amino acids is that it can be found in parts of protein structures in humans and can also be found in several foods consumed by humans like Sugar Cane, meat , and dairy products. glycine also has a hydrogen side chain which is absent in other amino acids.
Hence we can conclude that To make glycine ( amino acid ) from glucose ; Oxygen, carbon or hydrogen is needed and they come from the consumption of Protein-rich food and from respiration.

As you have observed, animal hairs usually have a large medulla composed of air-filled compartments. These air-filled compartments are present for a reason and can actually help hair do its job better. Describe one reason that might explain why having a hair made of air filled compartments could be helpful to an animal.
PLEASE HELP
Answer:
to provide insulation
Explanation:
The medullary index is the proportion of the diameter of the hair medulla in regard to the diameter of the entire hair: The equation to calculate the medullary index is medulla diameter/hair diameter. In animals, the hair medulla is generally thicker compared to humans (medullary index approximately 0.5 and 0.33, respectively). The thicker the diameter of the hair medulla, the better is the insulation.
