Answer:
The outer planets are also called gas giants; The outer planets have a high gravity due to their large size; The outer planets formed where temperatures were cooler
Explanation:
All planets in our solar system can be divided into two groups; inner and outer planets. Border between these two groups is the asteroid belt. So, all the planets further from the asteroid belt ( Jupiter, Saturn, Uranus and Saturn) are called outer planets. They all have some characteristics in common:
- they are huge in size, several times bigger than the Earth, and since they are mostly composed of gases they are referred to as "gas giants"
- since the gravity of a planet is directly proportional to its size, these planets have higher gravity, which is why outer planets have multiple moons and rings
- since they are very far from the heat source, the Sun, they were formed in a cold part of space and their temperature is lower
Although Pluto also is further from the asteroid belt, it does not fulfill all the criteria to be a planet; officially, its status is a dwarf planet.
<span>Immunity always needs white blood cells, which can be granulocytes ( neutrophils, basophils, monocytes, macrophages and oesinophils ) , or lymphocytes ( which can be B cells or T cells )
There are two systems : Innate and Adaptive immune response
There are 2 types of immunity : humoral and cellular within the Adaptive immune response
Humoral immunity refers to B lymphocytes. When there is a pathogen circulating in the peripheral blood flow, B lymphocytes recognises their surface antigens ( through the aid of antigen presenting cells like macrophages and dendritic cells) and induce production of plasma cells, which faciliate production of immunoglobulins ( 5 types), which aid to the removal of pathogens ( but not killing them)
Once the pathogens get into tissue or cells, humoral immunity can not be effective anymore. So this is when cellular ( or cell-mediated immunity ) is mobilised. These are T lymphocytes. There are a few types. T CD4 ( or T helper cells), which act as co-stimulation for B cells production of immunoglobulins and fight against certain pathogens. T CD8 cells ( cytotoxic T cells ) are the ones that have major role in killing all cells and tissues that are infected by secreting perforins which basically create pores in the infected cells, leading to cell death ( death by apoptosis). There are also NK cells ( natural killer cells ) which basically are licensed to kill anything that is " not normal " such as malignant cells.
The B and T cells response above belong to the adaptive-immune response.
Another immune reponse system which is short-lived and immediate is the INNATE immune response which include the granulocytes stated at the beginning to this answer. Upon infection, these cells will be immobilised immediately to rush to the site of infection or exposure to seek and destroy any thing that is considered foreign ( neutrophils will fight against bacteria, oesinophils and basophils fight against parasitic infection and induce allergic and hypersensitivy responses ). Note that the innate immune response is for quick response, and they are not involved in long-term protection as is provided by the adaptive-immune response. They are also not likely to be able to fight against viral infections.</span>
When the cells undergo late apoptosis, the membrane structure is destroyed and the nuclear structure can be selectively visualized by Hoechst 33342/PI.

Im not sure but if there was a graph maybe
