Explanation:
if a car is traveling at an average speed of 70 kilometers per hour, how long does it take the car to travel 14 kilometers?
Answer:
12 minutes
Explanation:
60x14 /70
The time it would take a car to travel 14 kilometers if it were traveling at an average speed of 70km/hr is 5 hours.
How to calculate time?The time it takes for a car to travel at a certain speed can be calculated using the following formula:
Distance = speed ÷ time
Hence, time = speed ÷ distance
According to this question, a car is traveling at an average speed of 70 kilometers per hour, the time taken can be calculated as follows:
Time = 70km/hr ÷ 14km
Time = 5hours
Therefore, the time it would take a car to travel 14 kilometers if it were traveling at an average speed of 70km/hr is 5 hours.

Which immune cell is part of acquired immunity?
A. Macrophage
B. Eosinophil
C. Plasma cell
D. Neutrophil
Answer:
C. Plasma cell.
Explanation:
Acquired immunity is developed in the body following a previously encountered infection. The innate immunity by definition, always present in the body and is used to attack all general forms of infection.
The granulocyte cells are considered part of innate immunity and help mediate the immune response against foreign pathogens. These cells include basophils, neutrophils, eosinophils, mast cells, and macrophages (which are differentiated from monocytes).
The adaptive immune response involves the production of antibodies against specific target antigens. Plasma cells are an integral part of the adaptive response and secrete large volumes of antibodies in response to a secondary infection by a previously encountered pathogen. T-cells and B-cells are also part of the adaptive response.

What part of Schwann’s publication was wrong?
Answer:
The CELL THEORY, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin's theory of evolution (1859), Mendel's laws of inheritance (1865), and the establishment of comparative biochemistry (1940).
Ultrastructural research and modern molecular biology have added many tenets to the cell theory, but it remains as the preeminent theory of biology. The Cell Theory is to Biology as Atomic Theory is to Physics.

1. What is the major difference between an animal
cell and a bacterial cell?
Answer:
A bacterial cell is a prokaryotic cell. Animal cells are eukaryotic cells.
Explanation:
ANIMAL CELLS: They are the basic unit of life of organisms which belong to kingdom Animalia. They have a well-defined membrane-bound nucleus, cytoplasm surrounded by plasma membrane and membrane-bound cell organelles in the cytoplasm to perform specific cellular functions necessary for the normal functioning of the cell. They can be of various sizes and shapes. Their size generally ranges between 1 and 100 micrometers.
BACTERERIAL CELLS: It is a simple, unicellular microorganism which means all life processes like feeding, digestion, and reproduction occur in one cell. It lacks the membrane-bound nucleus and organelles like mitochondria, lysosomes and other specialized cellular structures to perform cellular functions like energy production, transport of proteins etc. The cell wall of the bacterial cell is made up of glycoprotein, murein. Its main function is to provide support, mechanical strength and rigidity to the bacterial cell
Answer:

B)waves that move through Earth
C)interactions between living things on Earth
D) diversity of life found on Earth
Geologists study waves that move through the Earth. So the correct option is B.
What is geology?The field of science that includes all the materials that have resulted in the formation of Earth and the interactions between these materials is called geology. It also studies the forces acting upon the earth and the biology of ancestral organisms based on their fossil records.
The study of many other fields of science is not possible without the study of geology. These are climatology, civil engineering, and evolutionary biology brig some of the many.
In geology, the process of the changes of the earth over time is also studied. These changes can be climate change and land formation.
The scientists practising geology are called geologists. Geologists study the processes of the earth like landslides, earthquakes, volcanic eruptions, and floods.
The investigation of earth materials not only includes metals and minerals but also oil, natural gas, water, and the required methods for their extraction.

A. somatosensory
B. visual
C. auditory
D. motor
The primary somatosensory cortex contains a map of the body based on the importance of sensory input from different parts of the body.
The primary somatosensory cortex is responsible for processing sensory information from various parts of the body, including touch, pressure, temperature, and pain.
It is located in the parietal lobe of the brain, specifically in the postcentral gyrus.
The primary somatosensory cortex contains a map of the body known as the somatotopic map. This map represents different body parts based on their relative importance and sensitivity to sensory input.
Areas of the body that require precise and fine sensory discrimination, such as the hands and face, are allocated larger portions of the somatosensory cortex compared to less sensitive areas.

Trapping has severely reduced the population of rabbits in an ecosystem, as shown in the bar graph below. What is the most likely effect this will have on other organisms? A bar graph shows types of populations on the x-axis and percent of balance on the y-axis from 0 to 200 by fifties. Grass = 100. Rabbit = 50.4. Snake = 100. Hawk = 100. a. The snake population will decrease rapidly and the grass population will increase rapidly. b. The hawk population will increase rapidly and the rabbit population will decrease rapidly. c. The grass population will decrease rapidly, and the snake population will increase rapidly. d. The grass, rabbit, snake, and hawk populations will all decrease rapidly.
Answer:D
Explanation
took test
Trapping has severely reduced the population of rabbits in an ecosystem, so the most likely effect this will have on other organisms is that the snake population will decrease rapidly and the grass population will increase rapidly, as in Option A.
What is a predator-prey relationship?Rabbits are prey species, which means they are hunted by predators such as snakes and hawks, and rabbits are also herbivores, which means they eat plants such as grass, so if the rabbit population is significantly reduced due to trapping, it could have several effects on other organisms in the ecosystem such as the predator species, the snake, will decline, but the grass will increase as the rabbit population decreases.
Hence, the most likely effect this will have on other organisms is that the snake population will decrease rapidly and the grass population will increase rapidly, which is option A.
