49. A car is parked on a hill. In order to keep the car from rolling downhill, how great must the static friction acting on the car be?a.
equal to the force pulling the car downhill
b.
greater than the force pulling the car downhill
c.
greater than the force pulling the car uphill
d.
smaller than the force pulling the car uphill

Answers

Answer 1

Answer: The answer is (a.) equal to the force pulling the car downhill

As long as the static friction of the car is least equal to the force that pulls the car downhill, the car is a rest. The static frictional force of the car increase to prevent any relative motion.

Why is carbon so abundant in living things when oxygen is the most abundant element on Earth? Carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures. Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gases Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits. Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.

If the heart becomes damaged or weakened, how will this affect the body’s systems? A. The muscular system will strengthen the heart. B. Only the nervous system will be unable to function. C. The circulatory system will not function well, which will affect all other body systems. D. Only the circulatory and respiratory systems will be affected.

Answers

If the heart becomes damaged or weakened, then the circulatory system will not function well, which will affect all other body systems (Option C).

The heart is a fundamental organ that forms part ofthe circulatory system.

This system (circulatory system) consists of blood, blood vessels (i.e., veins, arteries, capillaries), and the heart, which work together to carry out oxygen and nutrients to all body cells.

The heart is an organ responsible for pumping blood through these vessels to all cells of the body.

In conclusion, if the heart becomes damaged or weakened, then the circulatory system will not function well, which will affect all other body systems (Option C).

Photo 51 is a picture of the structure of DNA that was used to create a model of DNA. Who created the photo?James Watson and Francis Crick
Erwin Chargaff
Rosalind Franklin
Friedrich Miescher

Answers

DNA stands for deoxyribonucleicacid. It has a double strand that contains the genes (a hereditary material) ofthe organism. It was discovered by James Watson and Francis Crick. Their double-helixstructure was based on x-ray diffraction image named as Photograph 51 or Photo51. It was taken by Raymond Gosling, a pHD student under the supervision ofRosalind Franklin. They used this photo to determine the chemical and physicalstructure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin

In which sealed container would the organisms be able to continuously cycle O2 and CO2 gases?A. A terrarium with mice and wood shavings
B. An aquarium with fish and plastic plants
C. An aquarium with water plants and a snail
D. A terrarium with a frog and a pool of water

Answers

The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.

Answer:

The correct answer is C. An aquarium with water plants and a snail

Explanation:

In an aquarium with water plants and snail the flow of oxygen and carbon dioxide will be continuous because plants are able to do photosynthesis which release the oxygen as the byproduct and this oxygen will be used by snail and snail during respiration release CO2 which will be used by plants in the process of photosynthesis to make food for itself.

Therefore there will be symbiotic relationship between plants and snail because snail provides carbon dioxide to plant and plant provide oxygen to the snail and support their survival. Therefore in this container organism would be able to continuously cycle O2 and CO2. So the right answer is C.

Which of the following is part of the axial skeleton?arm

pectoral girdle

pelvic girdle

skull

Answers

The bone that is part of the axial skeleton is the skull. Theaxial skeleton refers to the part of the skeleton that consists of the bones ofthe head and the trunk of a vertebrate. In the human body, there are 80 bonesfound in the axial skeleton composed of six parts: the skull bones, theossicles of the middle ear, the hyoid bone, the rib cage, sternum, and thevertebral column.

Final answer:

The axial skeleton includes the skull, vertebral column, sternum, and rib cage. Out of the options, only the skull is a part of it.

Explanation:

The axial skeleton, one of the major parts of the human skeletal system, includes the skull, the vertebral column, the rib cage, and the sternum. Out of the options you've provided, the skull is a part of the axial skeleton. The arm is part of the appendicular skeleton, while the pectoral and pelvic girdle serve as connection points between the axial and appendicular skeletons and thus are not considered part of the axial skeleton.
