Answer:
c. causes cells to swell and burst, whereas apoptotic cells shrink and condense
Explanation:
These two mechanism are responsible for death of cells in multi cellular organisms.Apoptosis is naturally occurring process which is well organised and programmed.It is ensures the automatic death of old and worn out cells, needed for certain cellular developments. This is demonstrated by DNA fragmentation,cell shrinkage,and the break down of the nuclear walls.It can be initiated through two pathways of intrinsic and extrinsic,The latter leads to death from internal factors,while in the former is when external factor causes the death .
However,when cell death is influenced by external factors(toxins) in the cell environments,which lead to unpredictable or unregulated process leading to cell death ,the process is called Necrosis.it is demonstrated with the swelling and busting of the cell.and characterised with inflammation. It is an accidental death which causes injuries to the cells and tissues.

Explanation:
We know that the momentum of a body is defined as the product of mass and velocity of the body.
Let us now obtain the momentum for each item on the list;
Football player = 100 * 10 = 1000 Kgms-1
Skier = 60 * 20 = 1200 Kgms-1
Frog = 0.9 * 12 =10.8 Kgms-1
Meteorite = 0.1 * 1000 = 100Kgms-1
Base ball = 0.14 * 30 = 4.2 Kgms-1
Satellite = 3000 * 8000 = 24000000 Kgms-1
Steel ball = 2.0 * 2.8 = 5.6 Kgms-1
Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.

The different versions of genes are called alleles. Alleles are responsible for determining physical or notable characteristics and traits a specific person has. </span><span>
