Gregor Mendel was an important scientist, considered to be the founder of the science of genetics. His experiments on the crossbreeding of plants and the passing down of favourable traits, led him to establish the laws of Mendelian inheritance. He was using pea plants for his experiments and he was studying seven different pea traits: pea shape and color, pod shape and color, flower color, plant size and position of flowers.
Populations of organisms that have sigmoid growth curves
limited by the carrying capacity are called K-selected.
Species are divided into two selected species, R-selected
species and K-selected species. K-selected
species are <span>also called K-strategist. These are the species whose populations vary at or near the <span>carrying capacity <span>(K) of the </span></span>environment<span> in which they live.</span></span>
The right answer is the first phase of the general adaption syndrome.
The concept of stress was introduced by Hans Selye. He describes the mechanism of the adaptation syndrome, that is to say all the modifications that allow an organism to bear the consequences of a natural or operative trauma.
In fact, it is the double-perception of a state of divergence between a demand for adaptation at a given moment and the ability to cope with it. It is an energy expenditure. It can be positive or negative.
The stress syndrome evolves in three successive stages:
*"Alarm reaction": the defense forces are mobilized
*"Resistance stage": adaptation to the stressor
*"Stage of exhaustion": inexorably reached if the stressor is sufficiently powerful and acts a long time.
Answer:
The concept of population neural coding proposes that a specific object, like a face, is represented across a number of neurons.
Explanation:
Neuron coding is processing the information by neurons, in a way that neurons generate electric impulses for coding. In population coding, the neurons give responses that could combine and that is how the entering information is determined.
Answer:
The first one: HH Hh Hh hh
Explanation:
Those are the genotypes - the phenotypes are the physical attributes the person will have. If there is the dominant gene (capital H) the child will have hitchhikers thumb. There is a 75% chance the child will have hitchhiker thumb and a 25% chance they will not.
