The truth about blood buffering is that 1). mantains the ph of blood near to 7.4. 2) utilizes the H2CO3/HCO3– conjugate acid/base pair and 3) is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid. Have in mind that the buffer is written as the following: <span>CO2(aq) + H2O(l) <==> H+(aq) + HCO3^-(aq) </span>
Balamuthia mandrillaris is an amoeba that was discovered in 1986 in the brain of the baboon that dies in San Diego Wild Animal Park. This can be found in the soil and water, therefore it is freely living. It is known to cause the neurological condition known as granulomatous amoebic encephalitis. In a study published by National Center for Biotechnology Information, it has a case fatality rate of >98%. Majority of this case can be found in warmer regions that affects individuals mostly of Hispanic origin. Documented cases had been reported from the Latin Americas in significant number, followed by the United States, Asian regions and some in Europe. However, a specific number of cases worldwide may never be known due to the following factors: lack of awareness, poor diagnosis and a poor public health system.
It is still yet to be known if its a serious public health concern worldwide.
Answer:
The mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.
<h2>Answer </h2>
- Hybridization
- Recombinant DNA
- Selective Breeding
<u>Explanation</u>
1. Cross-breeding; a method that unionizes gametes of differing genes to create a new individual is hybridization. It is the idea of combining atomic orbitals into different hybrid orbitals that is proper for the pairing of electrons to create chemical bonds in valence bond as per the atomic theory.
2. Cultured DNA molecules from different biological sources is recombinant DNA. They are the molecules are DNA molecules determining by laboratory techniques of genetic recombination to take mutually genetic material from various origins.
3. A process of breeding organisms because of their specific traits is selective breeding. It is the method that grants humans practice animal breeding and plant breeding to selectively develop selective over phenotypic traits
Answer:
b) opening calcium pores in the membrane
Explanation:
The opening of calcium ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons to the tip of the post-synaptic membrane. at the <u>neuromuscular junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u> <u>At the tip of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>
The neurotransmitters, diffuse through the neuromuscular junction to bind with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is up to the threshold levels it generate action potential.
Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP generation.
