How do humoral and cell mediated immunity help each other
Please help me thanks
Humoral immunity protects the body against extracellular pathogens and Cell mediated immunity protects the body from intracellular pathogens .
Humoral immunity: It is the process adaptive immunity manifested by the production of antibodies by B lymphocytes. It develops the bone marrow. B cells may be trigged to proliferate into plasma cells.
Cell mediated immunity: Cell mediated immunity is an immune response that does not involve antibodies but rather involves the activation of macrophages and NK cells.
Humoral immunity and cell mediated immunity works together with assistance from helper T cells, B cells.

30 POINTS
Answer:
number 3 is the central vacuole and its large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell
Explanation:
Answer:
3. Vacuole
Explanation:
Plant vacuole is a membrane (tonoplast) bound space which contains sap, water, excretory products and other materials (which are not useful for plants).
It occupies 90% of the volume of the plant cell. Tonoplast, in plants facilitates transport of ion into the vacuole (against the concentration gradient) which causes higher ionic concentration in vacuole than in the cytoplasm.Some other points:-
Amoeba have contractile vacuole for osmoregulation and excretory purposes. Some protists develop food vacuoles by engulfing food particles.The energy required for organisms to respond to the environment comes from:.
The energy required for organisms to respond to the environment comes from the sun.
What is the importance of the Sun in the ecosystem?Light energy, which also comes from the Sun, is essential for photosynthesis, a process in which green vegetables transform carbon dioxide and water into glucose, lipids, proteins, vitamins, nucleic acids, releasing oxygen into the atmosphere.
The sun is the basis of life, because if we analyze the food chain, its base comes from the photosynthetic beings that provide food for this chain to occur.

A rabbit is eating leafy plants on a sunny day. What is happening to the
carbon in the plants and in the rabbit?
The carbon in the plants and the rabbit is : Moving in and out simultaneously
The carbon cycleThe carbon cycle explains the reusing of carbon atoms which enters the earth from the atmospheres and its movement back to the atmosphere ( reuse ).
As the rabbit eats from the leafy plant the carbon it absorbs from the consumption of the plants enters into the atmosphere simultaneously. while as the leafy plants loses its carbon to the rabbit, carbon is added to the leafy plants from the atmosphere.
Hence we can conclude that The carbon in the plants and the rabbit is : Moving in and out simultaneously

how has climate change over geological time and how may it change in the future?
Answer:
Climate has generally changed from warm to cool globally mostly because of glaciers. Our climate can be changed in the future by the glaciers, also. Think about it this way, glaciers in the south pole melt, and the sea levels rise. Wind currents shift the glaciers and ice shelves, so they break. This will cause the world to overheat, and sea levels to rise. That's how our climate has and will change over time.

Which of the following best describes the state of ecology and environmental science prior to 1960?
It was relatively non-existent, and most scientists in these fields were considered naturalists.
It focused on gathering evidence to support climate change.
It was a fairly popular field that focused on naturalism and conservation of wildlife.
It focused heavily on developed countries, rather than rural areas or wildlife.
The correct option is 'it was relatively non-existent, and most scientists in these fields were considered naturalists' because it describes the state of ecology and environmental science prior to 1960 (option 1).
What is environmental science?Environmental science is a field of study that analyzes the interactions of organisms and abiotic factors in a given ecosystem.
Environmental sciences are fundamental to fight against climate change and global warming.
In conclusion, the statement 'it was relatively non-existent, and most scientists in these fields were considered naturalists' describes the state of ecology and environmental science prior to 1960.

Look at the diagram below.
Ray 1 from the Sun moves through air and falls on the surface of a lake. Ray 2 is a ray which travels from the surface of the lake at the point Ray 1 strikes the lake, and moves towards air. Ray 1 and Ray 2 make the same angle with the surface of the lake. Ray 1 bends towards the vertical when it enters the lake as Ray 3
Which statement is correct about Ray 1?
Ray 1 from the Sun is the incident ray which is first refracted and then is reflected off the water surface as Ray 2.
What are rays of light?Rays of light are packets of light which travel together in a straight line.
Light rays just like other waves can be reflected, refracted, diffracted, and polarized.
The ray of light Ray 1 from the Sun is the incident ray.
Ray 2 that leaves the water surface is the reflected ray..
Therefore, Ray 1 from the Sun is the incident ray which is refracted and then is reflected off the water surface as Ray 2.

what does it mean when a plant photosynthesizes at maximum speed?
Answer:
High stomatal conductance
Explanation:
Plants with a high photosynthetic capacity have a high stomatal conductance, in the absence of environmental stress (Reich et al., 1999, 1997). This enables plants with a high photosynthetic capacity to gain carbon rapidly, at the cost of high rates of water loss.

the owl in this diagram is considered to be a
carnivore
scavenger
omnivore
herbivore
Answer: carnivore
Explanation:
To answer this question, we need to define the given answers and look at what the owl eats via the diagram. Then we will decide what the owl is considered to be.
Here are simple definitions for the given answers:
Carnivore: eats only animals
Scavenger: eats dead organisms
Omnivore: eats both plants and animals
Herbivore: eats only plants
Next, we will look at what the owl eats via the diagram. See attached. The owl eats frogs, snakes, squirrels, rabbits, and mice (these might not be the exact animals, I am assuming based on the picture). All of these are animals that appear to be alive, meaning the owl is a carnivore.
write 7 differences between cell and virus.
Hey there! Here are 7 differences between a cell and a virus:
A cell is a significant structural and functional unit of all living organisms. Instead, a virus is an infectious agent that is considered non-living. The cell is a living component, unlike a virus that is a parasite. Cells are present in a living form, on the other hand, the virus is present in both living and non-livingA virus doesn’t contain any kind of cytoplasm, cell wall, cell membrane, ribosome or mitochondrion, whereas a cell contains all of these (depending on what kind of cell it is). Many viruses do not even have a membrane, often formed of only a protein capsid containing the DNA or RNA based genome. Cells can exist independently like bacteria or can be as a part of larger organisms like our own cells in the body. Viruses on the other hand are non-living infectious particles that are dependant on a living host to reproduce.Cells reproduce through binary fission and mitosis or meiosis. When a virus replicates, it uses lytic fission to do itVirus particles are slightly smaller than a cell.Hope this helped. Explanations and examples are included within the points.
