Answer:
1.They produce white blood cells.
2.They recognize specific pathogens.
Antibodies protect the diseases by two ways by recognizing specific pathogen and by producing WBCs.
what are antibodies?Antibody, also known as immunoglobulin, is a protective protein generated by the immune system in reaction to the presence of an antigen, which is a foreign material. Antibodies are proteins that identify antigens and latch on to them in order to eliminate them from the body.Antibodies also produce white blood cells.They recognize specific pathogens.Hence the correct option is 1, 2.

List three particles found in blood plasma and give their main purpose.
Answer:
Blood plasma is a 'yellowish liquid' component of blood that holds the blood cells in whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume. It is the intravascular fluid part of extracellular fluid. It is mostly water, and contains important dissolved proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders.

Devegetation affected a number of nutrient reservoirs and processes in the experimental watershed. Note that the rate of decomposition was not affected by devegetation because the decomposers were not affected by the treatments and because the plant remains contributed plenty of organic nutrients to the soil to sustain decomposition for the duration of the experiment. Drag the labels to indicate the change in the size of the reservoir or the change in the rate of the process as a result of devegetation. Labels may be used once, more than once, or not at all.
Answer:
Devegetation affect the nutrient reservoir and watershed due to not using of nutrient and increases soil erosion.
Explanation:
Devegetation refers to no vegetation on a piece of land. If there is no vegetation present on land, the nutrient reservoir remain full because no plant is available for the absorption of nutrients from the reservoir. Devegetation also affect water quality of watershed. Erosion is the main problem of those areas where there is no vegetation and the upper layer of soil is washed by the rainfall.
Which region would likely have the greatest amount of biodiversity?
OA
B.
a mountainous region with two ecosystems, each of which supports a few different species
a grassland region with one ecosystem, which supports very large populations of a few different species
a coastal region with three ecosystems, each of which supports many different species
a cave region with one ecosystem, which supports small populations of many different species
D.
Answer:
A
Explanation:
A coastal region with three ecosystems, each of which supports many different species likely to have the greatest amount of biodiversity. The correct option is C.
The highest level of biodiversity would probably be found in a coastal area with three different habitats.
Because there are so many different habitats and ecological niches along the coast, there is frequently a high biodiversity there.
Sand beaches, rocky shorelines, coral reefs, mangrove forests, and salt marshes are just a few examples of the diverse environmental conditions that can be found in a coastal region due to the interaction of marine, estuarine, and terrestrial ecosystems.
There is a larger total species variety because various species are supported by each ecosystem and are adapted to their own habitats and environmental variables.
Additionally, because they produce intricate and interconnected ecological networks, interactions between different habitats further improve biodiversity.
Thus, the correct option is C.

D) A, B, C, D, E
Explanation:
These are all important factors to consider when judging scientific theories. A scientific theory is not merely an inclination or vague idea a scientist has. Instead, a scientific theory is an explanation that is given to a broad range of phenomena. Scientific theories tend to be concise, coherent, systematic and predictive. However, they also admit modification as new evidence becomes apparent.

Imagine an object launched from Earth as shown in the image. Identify where the object has overcome the gravitational pull of Earth.
Answer:
the object defeats the force of gravity on the arrows on the left where they do not follow the circumference of the earth.
since the force of gravity makes the objects keep rotating near or even on the Earth's surface.
If any object overcomes this force, it will not rotate on the surface of the earth and will not be attracted to the center
Explanation:
this is because the center of the earth works as if it were a magnetic pole that attracts everything close to the earth to its center, if something deviates as in the arrows on the left, it means that the force of attraction towards the center or force of gravity does not act on the objective as it must have a force applied or of its own greater than that written

The bunnies in a forest have different colored fur at different times of the year. The bunnies you see have brown fur in the fall. The bunnies you see in winter have white fur. What is this an example of?
a. Evolution
b. Artificial Selection
c. Natural Selection
d. Selective Breeding
Answer: A) Evolution or B) Natural Selection
Explanation: The fur of these bunnies change color with the seasons in order to better blend into their environment. This is an example of a species evolving to better survive!
However, this could also happen as a result of natural selection. Those who were able to better survive would pass on their genes for fur that changes with the seasons.
Describe what the observations imply about how starlings are affected by flocking behavior in the wild and explain how evidence suggests that flocking behavior provides an advantage to starlings.
Answer:
Explanation:
Starling is a bird from the family sturnidea. It originated from Europes and Asia from where it introduced to other part of the world. They lives in the wild.
Starling birds moves in group or tight flock from a place the other. They usually form a flock called murmuration where they move together in group following each other to avoid predation.
Starling have been able to survive on the wild with this behaviour. They stir above the average height of their neighbor in a coordinated manner preventing them from being caught by preys.

Answer:
Translation- The presence of an organized nucleus inside the cell is characteristic of: a) prokaryotic cell b) eukaryotic cell c) bacteria d) viruses
Explanation:
Eukaryotic.These organim including man, are characterised with a double membrane nucleus, with all its inclusions. Other organisms lack a well organized membrane bounded nucleus. Rather they have orgellells that perform nearly similar functions close to the nucleus lying freely in the cytoplasm.
Nucleus is the control and coordinating centre of the cell.Genetic materials needed for instructions on how to produce other cells organelles are present in the nucleus.
Bacteria, Prokarotes contain Nucleoid, which is just an irregularly shape region, lacking nuclear membrane.
Viruses lack Nucleus.
Do you think it would be possible to construct a pyramid where the number of carnivores was more than the number of herbivores? Why or why not?
Do you think it would be possible to construct a pyramid where the biomass of carnivores was more than the biomass of herbivores? How does this compare to a numbers pyramid.
Please help!
Answer:
Explanation:
Pyramid is the use of graph to represents the flow of energy in each trophic level. There are five trophic level and each has its own energy level pyramid help to show the energy at each level.
Each energy level must have at least One tenth of the energy level of the organisms before itself, this indicates that the energy in the lower tropic level is higher than the trophic level above.
Hence, carnivores cannot be more than herbivores in a biomass they need enough of herbivores to survive in the biomass as the energy level moves from the herbivores to the carnivores.
