As the algae and other plants begin to die, they cause the bacterial population to explode. The bacteria exhaust the supply of dissolved oxygen needed by animals living in the water. What will happen to the minnow population?
Answers
Answer:
The population of these fish will decrease, because they will end up dying from lack of oxygen.
Explanation:
The low concentration of oxygen in the water is very harmful to fish.
Fish, when exposed to a low concentration of oxygen in the water, even for a short period of time, do not face so many problems as long as other water quality parameters such as pH, ammonia, and nitrite are at acceptable levels. However, a permanent value below 60% saturation is intended to cause problems in fish health. Most survive a few days with a saturation of 40%, but if the oxygen concentration drops quickly, the fish will begin to feel the effects of the lack of oxygen and will eventually die.

Which of the following nucleotide base sequences complements the section of DNA modeled above?
5’ UTCGCA 3’
3’ AATCGC 5’
5’ GCGATT 3’
5’ TTUCGC 3’
Answers
The given DNA sequence is 5’ TTAGCG 3’ . According to Chargaff's rules state that Adenine is always pairs with thymine and guanine is always pair with cytosine. So in the given sequence 5’ TTAGCG 3’ the nucleotide base sequences complements the section of DNA is 3’ AATCGC 5’. Hence, option 2 is correct ,because it follows chargaff's rules and complementry strand always read in 3' to 5' as DNA sequence present in 5' to 3'.
Answer:
Option B is correct. The 5' TTAGCG 3' will complement with 3' AATCGC 5'.
Explanation:
In dsDNA one strand is 5'-3' while other is 3'-5'.
According to the complementarity rule
the Adenine(A) always bond with Thymine(T)Guanine(G) always bond with Cytosine(C).Options other than B are 5'-3' same as first strand. Hence Option A,C, and D can be eleminated.
Therefore 5' TTAGCG 3' will complement with 3' AATCGC 5'.

Hello!
For background the plant shown is an orchid. Generally, purple is the dominant color and trait within this species and white the recessive allele.
If we use Mendell's Punnett Square we can actually see that together the pair are codominant with one another.
So the answer to your question would be, c. codominant with the allele for the white flower color.
If only one particular color was showing, we could say that one was dominant over the other. However, due to the fact that both traits show, that means they are codominant ! As recessive genes will not show under the presence of a dominant gene.

Think about the two words that make up the term reproductive isolation. How do you think reproductive isolation affects the evolution of a species?
Answers
Answer:
Reproductive isolation refers to the inability of an organism or species to breed successfully with other organism or species.
It may arise from various factors such as:
Geographical isolation such as river, mountain, etcBehavioral changes such as mating time or season, mating rituals, mating location etc.Physiological differences such as change in shape of sex organs which causes lack of fit between copulatory organs.Genetic differences.Reproductive and geographical isolations between two populations (of same species) inhibit the flow of genes among them. Slowly, these isolations increase the variations in the gene pools of the two populations.
These genetic variations keep on increasing with time. In addition, as an adaptation to their surrounding or habitat the two populations would develop different behavioral and physiological changes
With time, these differences will increase up to such an extent that the two populations would not be able breed with each other. Hence, it would lead to the evolution of one or both the populations into new species.
PLATO:
Reproductive isolation refers to populations of organisms that have become isolated from each other. A geographical barrier or a genetic change can cause this isolation. As a result, the organisms are not able to successfully reproduce with each other. The two populations evolve separately from each other, likely developing different frequencies of genetic mutations and possibly selecting different traits.

List and explain three of the factors that determine how quickly rock is weathered
Answers
So here are some factors:
- Height: the lower to the ground, the more particles wind carries, which is where we'll notice weathering the most.
- Type: there are different types of rocks, each of them with a different hardness, and the harder a rock, the more difficult it'll be to weather.
- Location climate: a rock in a place with weak winds and not that much rain will take longer to weather.
Hope it helped,
BioTeacher101
Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind, and ice.
The factors that determines how quickly are:
CLIMATE: The amount of water in the air and the temperature of an area are both part of an area's climate. Moisture speeds up chemical weathering. Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates.Rainfall and temperature can affect the rate in which rocks weather. Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.Which statements describe Newton and the law of universal gravitation? Check all that apply
Answers
Newton's Universal Law of Gravitation states that each particle in the universe attracts every other particle with a force that is directly proportional to their masses and inversely proportional to the distance squared between them. Newton's formulation is essential for understanding gravitational forces in classical physics and is foundational for calculating planetary orbits and terrestrial gravity.
Understanding Newton's Law of Universal Gravitation
Sir Isaac Newton formulated the Universal Law of Gravitation, which revolutionized our understanding of how objects in the universe interact through gravity. This law states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses. This gravitational force is also inversely proportional to the square of the distance between the particles.
The formula for Newton's universal law of gravitation can be expressed as F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two particles, and r is the distance between them. This law has been key to understanding celestial mechanics and is a cornerstone of classical physics. It is also the fundamental principle understanding the orbits of planets and the behavior of objects under the influence of gravity on Earth.
However, it's important to recognize that Newton's law was later supplemented by Einstein's theory of general relativity, which gives an even more accurate description of gravitational phenomena, especially near very massive objects or at very high velocities. Nonetheless, Newton's law of universal gravitation remains a crucial tool for common gravitational calculations in everyday situations where general relativity has negligible impact.
