Long-term survival of any species is possible only if the organisms -
A migrate during cold seasons
B hide from predators
C locate a constant food source
D reproduce successfully
Answer:
D
Explanation:
In order for a species to live on, they must reproduce successfully to have continuing generations. A is not right because not all animals migrate. B is correct, but that does not apply to the long-term. C is also important but it is not correct because it also does not apply to the long term. This makes the answer D.

Many of the factors that led to the end-Permian mass extinction also contributed to the end-Cretaceous mass extinction, with the exception of ______.
Many of the factors that led to the late Permian mass extinction also contributed to the late Cretaceous mass extinction, with the exception of a meteor strike.
Permian-Triassic extinctionThe biggest mass extinction event in Earth's history occurred about 250 million years ago and wiped out 96% of marine life and 70% of land life. Known as "the great death", it was a period of extreme volcanism on the planet, in the region of Siberia.
Cretaceous-Paleogene extinctionOccurred only 66 million years ago, it decimated 75% of species. All non-avian dinosaurs were killed. Unlike the previous ones, this event was caused by an external agent: an asteroid over 13 kilometers wide plunged into Earth at 72,000 kilometers per hour.
Whit this information, we can conclude that many of the factors that led to the late Permian mass extinction also contributed to the late Cretaceous mass extinction, with the exception of a meteor strike.

But one of the models i am playing around with red shift, is that part of the red shift is due to the photons dragging on space, and this causes the photons to loose energy, and move in the red direction. This in turn eliminates the need for a geometric expansion of space, which i am having an awful time getting right.
If photons drag on space, it means there is some kind of proper motion, which we see in the relation of blue-shift v red-shift. Dopler effect is relative to the ether, and the idea that energy changes in frame reference gives some sort of geometric issue.

If an organism's DNA contains 33% adenine nucleotides and 17% guanine nucleotides, what percentage of its DNA is composed of cytosine nucleotides
A DNA with 33% adenine and 17% guanine nucleotides respectively will contain 17% cytosine.
Purine to Pyrimidine ratio in DNAAccording to Chargaff's rule, the ratio of purine to pyrimidine bases in DNA is constant.
Since adenine always pairs with thymine and guanine always pairs with cytosine, adenine to thymine and guanine to cytosine ratios would be constant as well.
Thus, if a DNA contains 17% guanine, it will also contain 17% cytosine.

Add a few toy houses in various places along the riverbank in your model. Your houses should be on top
of the sand, and directly on the river's edge. Describe what happens to the houses over time as the water
flows through the river. Based on your observation, describe the negative impact erosion can have on
human settlements around rivers.
In task 2 I only did part D
answer:
Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.
