aquatic plants do not contain
a) chloroplasts
b)cells
c) lignin
d) nuclei
e) chlorophyll
c) lignin
Explanation;Aquatic plants are plants that live within watery environments, they serve as food and habitat for animals living in the sea and prevent shorelines, ponds and lakes from eroding by providing soil stability.Aquatic plants have less rigid structure since water pressure supports them.The cell walls of all vascular plants contain a polymer called lignin. Lignin is water-resistant polymer which reinforces cell walls, keeping them from collapsing.Aquatic plants lack lignin as they are supported by water pressure which prevents them from collapsing and reinforces the cell walls.How is extra nitrogen getting into the ecosystem
Extra NITROGEN can be leaking into the atmosphere through the NITROGEN cycle. The nitrogen is the most in the air at the moment so the nitrogen cycle takes the nitrogen round and it's leaked back out in different forms
The extra amount of nitrogen get back into the ecosystem by the combustion of fossil fuels and the use of nitrogen-containing fertilizers in the agriculture of crops.
What is Nitrogen cycle?The nitrogen cycle moves nitrogen element back and forth between the atmosphere and the living organisms. Bacteria are responsible for the change of nitrogen gas from the atmosphere to the different nitrogen compounds such as ammonia, nitrate, nitrite which the roots of plant can absorb. Other bacteria which can change nitrogen compounds back to nitrogen gas, helps this gas to re-enter the atmosphere.
In general, human activities release nitrogen into the environment by the two main processes which are combustion of fossil fuels and the use of nitrogen-containing fertilizers in agriculture. Both of these processes increases the level of nitrogen-containing compounds in the atmosphere.

Which layer of the digestive tract contains the effectors for digestive propulsion?
the answer is muscularis externa
Final answer:
The muscularis externa is the layer of the digestive tract that contains the effectors for digestive propulsion.
Explanation:
The layer of the digestive tract that contains the effectors for digestive propulsion is the muscularis externa. The muscularis externa is the third layer of the alimentary canal and is responsible for the contractions that promote mechanical digestion, expose food to digestive chemicals, and move the food along the canal. It consists of smooth muscle layers, including an inner circular layer and an outer longitudinal layer.
Normal blood pressure is 120/80. Which best describes the blood pressure reading?
The first number (120) is the systolic blood pressure. This is the pressure reading once the heart pumps, send a large volume of blood coursing through the artery and causing there to be more pressure in the artery at that moment.
The second number (80) is the diastolic pressure. This is the pressure reading after the heart has pumped and is refilling with blood. The diastolic reading is lower than the systolic reading because there is a lower volume of blood flowing through the artery after that initial pump from the heart, and therefore there is less pressure in the artery.
***see attached pic***
Answer:
The systolic pressure is 120, and the diastolic pressure is 80.

After which checkpoint is the cell first committed to continue the cell cycle through M?
A) G0B) G1C) G2D) SE) previous M
The correct answer is: B) G1
Normal cells (unlike cancer cells), move through the cell cycle in a regulated way in order to make sure that cells don't divide under conditions that are unfavorable for them. Information about their own internal state (nutrients, signal molecules, DNA integrity) is signal to go or not to go through the cell division. Because of that there are few checkpoints in the cell cycle at which the cell examines the signals and makes a “decision”. The major checkpoints are:
• The G1- the first point at which it must choose, once it passes the G1 checkpoint the cell enters S phase
• The G2-the cell checks DNA integrity and checks if replication is done well.
• The spindle checkpoint-at the transition from metaphase to anaphase.
Final answer:
The cell first commits to continue the cell cycle through the M phase after the G₁ checkpoint, where it assesses various conditions favorable for division; hence the correct answer is B) G₁.
Explanation:
The cell is first committed to continue the cell cycle through M phase after the G₁ checkpoint. This checkpoint, also known as the restriction point, determines whether all conditions are favorable for cell division, including adequate reserves, cell size, and DNA integrity. If these conditions are met, the cell commits to the cell division process and passes into the S phase. While the G₂ phase involves a checkpoint to ensure DNA replication was successful and the cell has enough materials for mitosis, the first commitment to proceed with cell division is at the G₁ checkpoint. Therefore, the correct answer to the question is B) G₁.

Answer:
The same reptile known as a river turtle in Illinois is called a cooter in Florida. This language phenomenon is classified as regionalism.
Explanation:
Regionalisms are words, expressions or attributions of meanings whose use is exclusive of a specific geographical area.
In the English language, those words or expressions of a locality or region that are not used in other places because there is an equivalent or they have a different meaning from the original are considered regionalisms.
The language phenomenon where the same reptile is referred to as a "river turtle" in Illinois and a "cooter" in Florida is classified as a dialect (Option C).
Dialects are variations in language specific to particular regions or social groups. They encompass differences in vocabulary, grammar, and pronunciation. In this case, the term "cooter" is a regional variation used in Florida to describe the same type of reptile that is called a "river turtle" in Illinois.
This difference highlights how language evolves and adapts to local cultures and environments, leading to distinct regional expressions for the same objects or concepts. Unlike synonyms, which are different words with similar meanings used within the same dialect, dialectal variations reflect the unique linguistic identity of specific areas, making "dialect" the correct classification for this phenomenon.

what are surfaces with high albedo and low albedo?
Albedo is the measurement of a surfaces ability to diffuse and reflect oncoming radiation, scores range from 0 ( an ideal blackbody that absorbs any and all incident radiation) to 1 ( an ideal white body that completely diffuses and reflects all incident radiation). A simple way to think about this concept is in the terms of sunlight, a black or darkly colored surface will always absorb much more of the heat (radiation) than a white or lighter colored one, for the lighter objects reflect the sun's energy much easier.
Answer:
This effect is nothing other than the reflection of solar radiation when it affects the planet. Light surfaces have more albedo reflecting most of the radiation and dark surfaces less albedo since they absorb radiation.
Explanation:
The albedo of all these combined surfaces is called the planetary albedo. The planetary albedo of the earth is approximately 0.31. That means that about one third of the solar energy that reaches the earth is reflected back into space and only about two thirds is absorbed. The albedo of the moon is 0.07, which means that only 7% of the energy that reaches it is reflected. The albedo of distant planets, so distant that they are difficult to study with telescopes, could be very helpful for scientists trying to determine what a planet is made of.
This effect is much greater the clearer the surface; for example, on snow or ice surfaces, up to 90% of the incident radiation can be reflected and therefore the UV rays would bounce continuously between the snow and the atmosphere. This effect is therefore a source for example of the thaw after glacial times, where with so much white surface the world temperature overheats and the glacier season ends.
The albedo effect is very significant for the human being, and more now when many of the defenders of the theory of global warming, come to their reasoning to explain how if the poles melt and there are less and less glaciers the earth by natural order is It will start to reheat faster.
Which of the following statements about the import of protein to the nucleus is correct? Choose all that apply.
An NLS can be a monopartite or bipartite signal which includes a significant number of basic amino acids.
GTP is required for an importin to bind to an NLS of a protein destined to be localized to the nucleus.
Ribosomal proteins must display an NLS to be localized to the nucleus, and an NES to be localized to the nucleolus.
The recycling of importins back to their original conformation requires GTP hydrolysis in the cytoplasm.
The correct statements are:
•An NLS can be a monopartite or bipartite signal which includes a significant number of basic amino acids.
• The recycling of importins back to their original conformation requires GTP hydrolysis in the cytoplasm.
The other answers are incorrect because GTP is not required for an importin to bind to an NLS but for the release of importin and an NES or nuclear export signal is the sequence in a protein for export from the cell nucleus to the cytoplasm, not to the nucleolus.

The drug AZT was one of the first drugs used to treat HIV. Which of the following drug actions would prevent the spread of HIV without harming the host cell?
prevention of the formation of glycoproteins
inhibition of reverse transcriptase
inhibition of DNA polymerase
destruction of amino acids that are vital to viral protein synthesis
The correct answer is: inhibition of reverse transcriptase
Reverse transcriptase is an enzyme with the ability to produce DNA (complementary DNA-cDNA) form the RNA template. Retroviruses, such as HIV virus after entering the cell, liberates the single-stranded RNA genome from the attached viral proteins and copies it into a cDNA molecule, That cDNA is than incorporated into host’s genome (via an enzyme integrase).
Antriretroviral medications such as AZT are inhibitors of reverse transcriptase, they decrease replication of the virus but not affecting the host.

Cutting down a rainforest and planting agricultural crops, such as coffee plants, would result in:
a decrease in erosion
a decrease in biodiversity
an increase in the amount of energy recycled
an increase in the amount of photosynthesis
Answer:
The correct answer is B a decrease in biodiversity.
Explanation:
Cutting down a rainforest has nothing to do with erosion so A is not correct. Cutting down a rainforest will not increase recycled energy so C is also wrong. Lastly a rainforest will have more photosynthesis being performed than agricultural crops. So D is ruled out. This leaves B because rainforests are filled with biodiversity and cutting one down would lead to a decrease in it.
Cutting down a rainforest generally results in a decrease in biodiversity and overall photosynthesis, and an increase in erosion. The dense vegetation and unique ecosystem of the rainforest play significant roles in nutrient cycling and energy flow, which are disrupted when replaced with agricultural crops.
Explanation:Cutting down a rainforest for agricultural activities like planting coffee plants mostly results in a decrease in biodiversity. Rainforests are home to many unique species of plants and animals, many of which are unable to survive in other habitats. When the rainforest is removed, these species lose their habitat and may become extinct, resulting in decreased biodiversity.
In terms of results on erosion, rainforest removal often causes an increase in erosion. The complex root systems of rainforest trees help to hold the soil in place. When these trees are removed for farming, the soil is more exposed and can be washed away by rain.
On the matters of energy recycling and photosynthesis, the cutting down of rainforests generally leads to a decrease in both. The dense vegetation of the rainforests plays a crucial role in the nutrient cycling and energy flow within the ecosystem. In addition, because rainforest trees perform photosynthesis at a much larger scale than crops, replacing them with agricultural plants actually reduces the overall rate of photosynthesis.

Animals that migrate great distances would obtain the greatest energetic benefit of storing chemical energy as _____.
fats - hope this helps!!
Animals that migrate long distances benefit greater from storing energy as fat. This ensures survival when food availability decreases and allows for a relatively constant body temperature in cold seasons.
Explanation:Animals that migrate great distances would obtain the greatest energetic benefit of storing chemical energy as fat, which is housed in specialized adipose tissues. Fat provides a more efficient long-term energy system, especially for the animals like elk who increase their metabolic activities and thus energy needs in winter. As such, having a threshold level of energy stored as fat in their bodies can ensure survival when the availability of food decreases. Furthermore, the heat generated from metabolism and stored as fat can help in maintaining a relatively constant body temperature, a characteristic of endotherm animals.
