Which of the following explains why the likelihood of survival is low for a fetus born before 32 weeks?

I believe the answer would be A) the fetus does not have fully developed lungs. When a baby is born at 32 weeks or less, there is a higher chance of the baby being born with respiratory problems because of the lungs being premature. Hope this helped!

One of the roles of ecological succession is to allow species with different adaptations to interact. Ecological succession occu
KIM [24]

Answer:

D overlap for a variety of species.

Explanation:

During ecological succession, a sequence of changes occurs in a community at a temporal and spatial level. Local colonizations and extinctions occur while ecosystems evolve at a more complex level.  

Ecological succession occurs in <u>stages</u>. The first stages are represented by communities of simple trophic levels and few species. With time, as the communities go through different stages, they transform into more complex ecosystems, that are much richer in diversity, and showing more interaction among the different species that compose it.  The final stage is known as the climax and represents a mature and stable system.

While the community is going through these changes, many species get extinct while many others get to emerge and survive. It occurs overlapping of different taxonomic groups that interact with each other competing or beneficiating other groups.

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.

An organism is discovered that thrives both in the presence and absence of oxygen in the air. Curiously, the consumption of suga
Vinvika [58]

A facultative anaerobe.

Explanation:

Anaerobes are organisms which can produce energy via the process of fermentation in the absence of oxygen. The anaerobes can be classified as facultative anaerobes and obligate anaerobes.

Facultative anaerobes are those which can carry out respiration in presence of oxygen but can choose to follow the fermentation pathway if oxygen is absent. Fermentation also uses glucose.

Aerobic respiration produces 32 molecules of ATP from one  molecules of glucose while fermentation produces only 2 molecules of ATP . Thus when the organism switches to fermentation pathway it utilizes more and more glucose to reach its energy demands.

Considering all the above points we can conclude that observations indicate that the organism is a facultative anaerobe.
