Why are plants unable to grow at the bottom of lakes ?
Answer:
I think its because of the water pressure
Explanation:
Answer:
I'm guessing that it's because there isn't enough sunlight at the bottom of a lake. The water reflects light, and plants need enough sunlight since they use photosynthesis to get their energy.
what chemical substances must be provided for aerobic respiration to take place inside the cell
Answer:
Oxygen
Explanation:
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

Which organelles are found only in plant cells and not in animal cells? cell membrane, vacuole cell wall, chloroplasts cell wall, vacuole cell membrane, chloroplasts
Answer:
Cell wall and Chloroplasts
Explanation:
I just studied hope its correct (～￣▽￣)～
Answer:
Cell wall and chloroplast
Explanation:
Plant cells are the fundamental building blocks of plants and they are eukaryotic because of the membrane bound organelles and nucleus also found in Animal cells.
Plant cells organelles are chloroplast and cellwall which is not found in animals.
Chloroplast is an organelle which contain the green pigment use for photosynthesis.
Cell wall is an organelle found in plant cell which contain cellulose, hemicellulose, liginin, pectin , soluble protein and microfibrils. It provide strength and protect the plant against mechanical or osmotic stress.

Explanation:
Experiment: Water Properties: Why were the results with just water so much different than the trials with the detergent?
Answer:
Explanation:
Water is a universal solvent whose molecule are joined together with a force of attraction. Its surface tension is hidden between bonds. When washing, soap is added for easy penetration of water molecule and to decrease the surface tension. This then allow the water to move freely round the object been washed.
Detergent aid the distribution of water, of water is used alone without the detergent then the surface area of water will not be reduced to all even spread. But, if detergent is added the tension is reduced and a better result is obtained.
Which molecular formula corresponds to this model of a chemical compound? (black = carbon; red = oxygen; white = hydrogen) A ball-and-stick model has two black balls bonded to each other at center, with single-bonded red balls bonded to white balls above left and below right, and double-bonded red balls above right and below left. C2(OH)4 C2H2O4 C2H4O2 C4H2O2
Answer:
C2H2O4
Explanation:
The molecular formula can be derived through the below analysis.
Two black balls (C) bonded to each other at the center = C2
Single-bonded red balls (O) bonded to white balls (H) above left and below right = (OH)2 = O2H2
Double-bonded red balls above right and below left = O2
Adding the three together = C2 + O2H2 + O2 = C2H2O4
The correct answer is C2H2O4

Which of the following can be determined based on this model?
A.
The atmosphere is the only reservoir on Earth that can store carbon in any form.
B.
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration.
C.
Dead organisms and waste products do not play any role within the carbon cycle.
Factories do not emit any amount of carbon dioxide into the atmosphere.
Answer: The answer would be B
Explanation: All plants and animals release at least some amount of co2 into the atmosphere during cellular respiration
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration can be determined based on the Carbon cycle model. So, the correct option is B.
What is Carbon cycle?The exchange and recycling of carbon in the Earth's biosphere, lithosphere, hydrosphere and atmosphere is known as the carbon cycle. All living things contain the element carbon, which is also an important component of many important compounds such as proteins, lipids, and carbohydrates.
Photosynthesis, respiration, combustion and weathering are just a few of the different processes that make up the carbon cycle. Plants use photosynthesis to take up atmospheric carbon dioxide and convert it into organic molecules. Plants and other organisms then use these molecules as a source of energy.
Therefore, the correct option is B.

A plant tissue made of tubular cells stacked to form structures called tubes.
A. xylem
B. cambium
C. phloem
Answer:
C
Explanation:
Xylem are stronger and thicker tubes than the Phloem, and the Xylem are meant to bring nutrients and water from the roots too the leaves!
Phloem are much smaller, and much more brittle than the Xylem, and they also have a different job. These are meant to take the glucose made from photosynthesis and move it to the rest of the plant. These are made up of tubular cells, creating a vascular system.

Explanation:
how has paraquat stopped the algae from making atp nadph and sugars
Answer:
This is by disrupting the mechanisms of photosynthesis.Paraquat is an herbicide. A photosynthesis inhibiting herbicides. In the light dependent reaction, It acts as oxidizing agent by accepting electrons from Photo system I. and lose these electrons to oxygen molecules which becomes oxidized.
Therefore, disrupting the electron transport chain.With the electron transport chain disrupted, PMF is inhibited, electrochemical gradients for generating energy for ATPs synthesis, by ATPase synthase enzyme is blocked.
Therefore, ATPs synthesis is prevented. With this, Calvin Cycle is blocked, so no CHO id formed. With lack of electron transport chain, NADPH will not be formed. .
Explanation:
Explain the unique bonding properties of carbon.
Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements.
What do you mean by valence electrons?A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed.
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table.

The term evolution is best described as. a process of change in a population through time.
Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms. An example of evolution is how cell phones have changed over time.
HOPE IT HELPS : D
Explanation:
Evolution is a very important phenomenon, which is the change in the characteristics of species of organisms over the course of life for the purpose of better survival.
What is evolution?The term “evolution” is best described as the process of gradual and continuous change in the inherited characteristics of a species over many generations.
This change is driven by mechanisms such as natural selection, mutation, and genetic drift, which lead to variation in traits within a population over time.
The theory of evolution by natural selection is widely accepted among scientists as the best explanation for the diversity of life on Earth. In addition to its importance in understanding the development of life on Earth, the concept of evolution has far-reaching implications for many areas of study, including medicine, agriculture, and conservation biology.

An important example of a "positive feedback loop" in the polar climate system is:
a.Scientists in remote places check on each others instruments.
b.Warming ocean water opens new areas for marine species.
c.Warmer winters cause more plant growth, providing more food.
d.Sea ice melt opens more ocean to sunlight, causing more melt.
Answer: D
Explanation:
A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.
In choice D melting of sea ice opens more ocean to sunlight which causes more ice to melt which demonstrated a positive feedback loop.
The significant example of a positive feedback loop in the climate system i.e. polar should be at the time when the ice of the sea should be melt that there should be more ocean that results in more melting.
The following information related to the positive feedback loop is:
If the direction varies so it should result in an extra change in a similar direction.Like if we take an example that if there is an increase in the substance concentration so it results in the feedback that generated the continued increase in the concentration.Therefore we can conclude that option d is correct.
All other options seem incorrect.
