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.

A poison placed on the tips of darts by natives of the Amazon rainforest paralyzes prey such as small mammals . Which of the prey's cells are most likely affected by the poison ?
muscle cells
epithelial cells
red blood cells
white blood cells
The cells in the prey that are most likely affected by the poison present in the darts are the muscle cells.
What are muscle cells?The muscle cells are a specialized type of cell (one of the four tissues) that is able to contract in order to exert movement.
These cells (muscle cells) can be paralyzed by using different inhibitors of movement such as poisons.In conclusion, the cells in the prey that are most likely affected by the poison present in the darts are the muscle cells.

A constant input of energy from the Sun is necessary to maintain any ecosystem. What contributes to the sustainability (balance) of an ecosystem?
A) Small Population sizes
B) Lack of adaptations
C) Polluted water source
D) Biodiversity (many different species of organisms)
Answer:
D) Biodiversity (many different species of organisms)
Explanation:
The ability to maintain the ecosystem and the surrounding nature is called sustainability. It is very important to for the sustainable development of the planet.
Biodiversity is the main contribution towards the sustainability of the ecosystem or maintaining a balance in the ecosystem. Biodiversity boosts the productivity of the ecosystem where each and every species, no matter however small they are, plays an important role in the ecosystem.

For this activity, you will be researching the Burmese python's impact on the Everglades National Park ecosystem in Southern Florida. These articles are an excellent place to start your research: Python and Impact of Invasive Alien Species.
After completing your research, you will analyze data on the current methods being implemented to control the python population and create a plan to solve the issue. You will then write a letter to the park ranger detailing your plan to control the python population in this ecosystem. Take a look at this student sample letter to see how your letter should be setup.
Burmese pythons are having a significant impact on the ecosystem and biodiversity in the Everglades and surrounding areas. As an invasive species, the python has no natural predator in Florida, making it an apex predator in the area. Therefore, the population of these snakes is not being naturally controlled.
Our innovative solution involves baiting the cages with pheromones, so that the snakes believe they are tracking the scent of the opposite sex. Since Burmese Pythons are usually solitary creatures, these traps will be especially useful during breeding season, to catch male pythons.

Explanation:
Jen and Ori are conducting an experiment to observe how sand and water absorb energy. They obtain two identical 1000-milliliter (mL) beakers, add 500 mL of distilled water to the first beaker, and 500 cubic centimeters (cm3) of sand to the second beaker. They place both beakers on a hot plate that is set to medium heat. Thermometers are placed in each beaker and held with clamps. Both beakers are heated for seven minutes and then removed from the hotplate and cooled for an additional fifteen minutes. Jen and Ori record the temperature of each beaker at one-minute intervals. How could Jen and Ori have increased the reliability of their experiment?
Answer:
I think that the answer should be B-repeated the experiment multiple times to see if they obtained the same results
Explanation:
This should be most reliable. Hope this helps!

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.

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.

The primary __________ cortex contains a map of the body based on the importance of sensory input from different parts of the body.
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.
