Answer:

B) the fuel for nuclear fusion is often uranium

D) nuclear fusion is used to generate electricity at nuclear power plants

Explanation:

Nuclear fusion is a reaction which involves two or more atomic nuclei being combined to form one or more different atomic nuclei and subatomic particles. The process of Nuclear fusion releases a large amounts of energy.

Nuclear fusion is used to generate electricity at nuclear power plants and it doesn’t require Uranium as its major reactant.

Answer:

B) the fuel for nuclear fusion is often uranium

D) nuclear fusion is used to generate electricity at nuclear power plants

Explanation:

Nuclear fusion is the term used to describe a situation that causes the union of two atoms of light nuclei. This union creates a fusion of these two light nuclei, generating a heavier nucleus. This union of light nuclei releases a large amount of energy and is common to happen in the nuclei of stars, such as the sun, for example.

Even with the strong release of energy, nuclear fusion is not used to generate electricity in nuclear plants, nor does it even need to use uranium as fuel.

The tracing of uterine activity measured with a solid-tipped intrauterine pressure catheter (IUPC) depicts no contractions. Howe
andreyandreev [35.5K]

The tracing of uterine activity measured with a solid-tipped intrauterine pressure catheter (IUPC) depicts no contractions. However, you are palpating contractions that are strong in intensity with a frequency of every 3 minutes and a duration of 60 seconds. A possible cause for this finding is (select an answer): The connections to the system are not connected.

An IUPC counts the number, length, and force of contractions. During palpations peaks of strong intensity is recored.As in this case IUPC seems to be not connected as its near impossible to get no contractions when palpation are high.

And one unit is the amount of pressure required to raise a mercury column by one millimetre. The intensity of the contraction is assessed from the baseline (when the uterus is relaxed) to the rise of the contraction and is recorded in units. According to studies, after spontaneous labour, 200 units of contractions per 10 minutes are typically sufficient for vaginal birth.

Based on the predictions of metapopulation biology, which scenario can be expected to exhibit the largest fraction of occupied h
harkovskaia [24]

Meta-population is the patchiness of population in space and its role is dynamic, population insatiability, coexistence of species, the maintenance of diversity.

Metapopulation is colonization and extinction dynamics. The variable of prime concern is the proportion.As the population largest approaches the environment carrying resources become more scare and growth rate slows.

The m maxima carrying number of species in environment can support indefinitely .A group of spatially separated population of similar organism which interact at some levels.It s population in which multiple populations as butterflies and cool reef fishes.Humans are evolved from multiple interconnected spread out across Africa in large meta-population.

Circadian rhythm refers to
strojnjashka [21]

Answer:

The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.

Explanation:

Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.

Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
