Answer:
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump up.
Explanation:
There are choices for this question namely:
<span>1 Pulse oximetry of 90%
2 Body temperature of 99° F
3 Heart rate of 40 bpm
4 Respiratory rate of 20 breaths per minute
</span>
The correct answer is "heart rate of 40 bpm". A heart rate of 40 bpm is classified as bradycardia. Bradycardia is defined as a slow heart rate below 60 bpm. A heart rate below 50 bpm is more than alarming to the health practitioner and suctioning should be stopped to give way for immediate intervention. A oxygen saturation of 90%, while below normal range of 95%-100%, is still considered safe. A body temperature of 99 degrees F and a respiratory rate of 20 breaths per minute is considered normal.
The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.
Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.
Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.
With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.
Answer:
They both go back and forth, such as the climate going from hot to warm, and the tectonic plates of the earth going from closed 300 million years ago to spreading far apart now.
The right option is; Segregation
The diagram represents the Mendel’s law of segregation.
The law of segregation is one of the principles of heredity discovered by Gregor Mendel. Mendel's law of segregation states that all organisms possess two pairs of alleles for each trait and that these alleles seperate during meiosis in a such a way that each gamete have only one pair of the alleles. The law explains that when an organism produces gametes, one gene copy is distributed to each of the gametes and that the selection of the gene copies is random.
