Scientists have identified a part of the brain that appears to be unique to humans. The brain region, called the lateral frontal pole of the prefrontal cortex, was described on January 28, 2014 in the journal Neuron, and is linked to higher thinking processes. "We tend to think that being able to plan for the future, being flexible in approach and learning from others are things that are particularly impressive about humans," said Matthew Rushworth, experimental psychologist at Oxford University.
This means that you can be "full" even on an empty stomach. Just that your bacteria are already satisfied. A new study in France shows that intestinal bacteria Escherichia coli (E.coli) produce appetite-suppressing proteins 20 minutes after meals. They release proteins from satiety after they have enough nutrients for themselves.
Blood (originated from hemocytopoietic tissue) is a highly specialized tissue made up of some types of cells, which make up the figurative part, dispersed in a liquid medium - the plasma - which corresponds to the amorphous part. Cell constituents are: red blood cells (also called red blood cells or erythrocytes); white blood cells (also called leukocytes).
Each plant and animal is characterized by a set of chromosomes, represented once in haploid cells (eg gametes and spores) and twice in diploid cells. Each species has a specific number of chromosomes. But irregularities sometimes occur in nuclear division, or "accidents" (such as radiation) can occur during interphase so that whole cells or organisms with aberrant genomes can form.
The animals that have cheloma are called cheloma. All chords are chelomated, as are mollusks (slugs, oysters), annelids (earthworms) and echinoderms (starfish, sea urchins). There are triblastic animals in which the mesoderm delimits one part of the cavity, the other part being delimited by the endoderm.
Pinocytosis In this case, the vesicles are small and the cell eats soluble molecules that would otherwise have difficulty penetrating the membrane. The pinocytic mechanism involves energy expenditure and is very selective for certain substances such as salts, amino acids and certain proteins, all of them water soluble.
