Answer:
no. badger vaccination is better
Explanation:
spreading mostly happens cattle to cattle
"killing badgers will not solve the problem. Badgers are not the primary cause of the spread of bTB in cattle: the primary route of infection is cattle-to-cattle contact[2]. The Government's badger cull is flying in the face of science. It should be putting more resources into speeding up the development of an effective cattle vaccine, amongst other measures"

Answer:
<em>Food and shelter are the most likely limiting factors in this case.</em>
Explanation:
In a forest, the huge trees act as a source of shelter for the animals that live in that habitat. It protects the animals from the heat of the Sun and extreme cold conditions.
The tress in the forest are the primary source of food for almost all the organisms that live in the forest. Cutting down trees will lead to food scarcity for the animals which inhabit that forest. As a result, the animals will either have to migrate or they will become die due to lack of food.
Hence, food and shelter are the limiting factors in this case.
He is WRONG
Explanation:
Any atom at the ground state has its orbital levels fill from the bottom (close to the nucleus) – up. The inner orbitals are of lower energy state and fill first because the atoms ‘likes’ to exist in the low energy and more stable state. Only when the atom is in an excited state do some of the electrons in the lower orbital levels shift to higher unfilled orbitals.
Answer:
The need for DNA replication
DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell will inherit an identical copy of the DNA.
Requirements for DNA replication
Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule.
Free DNA nucleotides – needed to form the new strands.
DNA polymerase – an enzyme that adds new nucleotides to a growing strand of DNA.
Primers – A primer is a short strand of nucleotides that will bind to the 3’ end of the template DNA strand allowing DNA polymerase to add free DNA nucleotides.
