How does natural selection impact a population

Biology
2 answers:
statuscvo [17]2 years ago
7 0

Answer:

People who acquire advantageous features have a greater chance of surviving, whereas individuals who have less useful traits are weeded out by natural selection. The higher the diversity of characteristics in a population, the greater the population's chances of survival.

natural selection is basically where stronger and smarter organisms survive and adapt. when a species changes locations or something happens to their habitat, they have to adapt. those that cant adapt will die off.

What does the guard cell do in photosynthesis?​
pishuonlain [190]
Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis

After researching the possible effects of music, Elaina proposes that if people listen to faster-paced music, their pulse rates
Angelina_Jolie [31]

Answer:

Constant variables

Explanation:

Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:

1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.

2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.

3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.

Damage to a brain area called the _____ would MOST likely interfere with learning a conditioned fear response to the sight of a
ELEN [110]

Answer:

The options

A)hippocampus

B)basal ganglia

C)hypothalamus

D)cerebellum

The CORRECT ANSWER IS D)

D)cerebellum

Explanation:

Apart from the coordinating process, the cerebellum is involved in motor learning, emotional behavior, and fear memory.

Fear learning is widely shown in the variation of autonomic and somatic responses, as in heart rate and freezing, promoted by a neutral stimulus which could have been formally grouped with a painful one.

Variation or changes of the vermis influences these responses, and its reversible inactivation in the period of consolidation which is seen to impair fear memory.

The neural correlate of cerebellar activities in fear consolidation is shown by a behaviorally promoted long-term rise of synaptic effectiveness and efficiencies among parallel fibers and a Purkinje cell.

Likely synaptic variations after fear conditioning are well fully observed in the amygdala and hippocampus, suggesting an interplay among emotional circumstances of scenario and the different variations in neural process.

Furthermore, in hotfoot mice, that shows a basic lack of parallel fiber to Purkinje cell synapse, short- and long-term fear memories are influenced.

All these data gives a foundational background on the concept that the cerebellum is majorly involved in fear learning.

The functional interplay of the vermis with hypothalamus, amygdala, and hippocampus do infer to a more complex activities of the cerebellum as a form of an united network that basically influences emotional behavior.
