Where does the water in the phloem come from?
Answer:
the leaf
Explanation:
Transpiration draws water from the leaf. Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the phloem. Transpiration draws water from the leaf.
A small piece of black paper was folded in half and used to cover part of the top and bottom portions of a leaf on a living geranium plant. After the plant was kept in sunlight for several days, the paper was removed. The leaf was then boiled in alcohol to remove the chlorophyll and placed in Lugol's iodine solution. Only the part of the leaf that had not been covered turned blue black. This investigation was most likely testing the hypothesis that
Answer: Light is necesarry for photosynthesis to occur
Explanation:
Based on the information given in the question, the investigation was most likely testing the hypothesis that light is necesarry for photosynthesis to occur.
Photosynthesis, simply means the process by which green plants transform light energy into chemical energy. It should be noted that during photosynthesis, light energy is captured which is then used in the convertion of carbon dioxide and water, into oxygen and energy which comes in form of sugar.
Answer: This investigation was most likely testing the hypothesis that SUNLIGHT is necessary for photosynthesis
Explanation:
Photosynthesis can be defined as the process by which plants (green plants) use inorganic compounds such as carbondioxide and water to manufacture their own food. This process is not only important to plants but also to animals which depends on plants for food. The main features of photosynthesis include:
--> it takes place in chlorophyll of plant cells
--> Raw materials needed for this process are inorganic compounds such as carbondioxide and water
--> Final products are organic compounds such as sugar and oxygen as by product.
--> Energy needed for this process is gotten from SUNLIGHT which is absorbed by the chlorophyll.
To show that sunlight is necessary for photosynthesis, an experiment is performed as stated in the question above. Only the part of the leaf that had NOT BEEN covered turned blue black because the exposed part has been actively photosynthesizing due to the presence of SUNLIGHT. While the covered part didn't undergo any photosynthesis as it tested negative for starch when placed in Lugol's iodine solution.

Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects? (1 point) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans, O All these organisms require oxygen to survive. O The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans. O Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.
Answer:
The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans,
Explanation:
It tells you that fish and humans have very similar embryo development (fetus development) while humans and insects develop very differently. Therefore, that supports the argument that humans are more like fish than insects.
Answer:
(Q1) Most people develop wisdom teeth by early adulthood. Wisdom teeth can cause pain or crowd out their other teeth, so many people have these teeth removed. Wisdom teeth in modern humans do not perform a crucial life function.
(Answer)They are vestigial structures that once performed an important function for human ancestors.
(Q2) Which statement is true?
(Answer) Imprints of leaves or footprints in sedimentary rock are fossils.
(Q3) Which statement about these fossils is supported by the evidence in the diagram?
(Answer) Homo erectus is the most recent ancestor to modern humans.
(Q4) Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?
(Answer) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.
(Q5) Human embryos have tails, which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals. Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?
(Answer) a close evolutionary connection between humans and many other mammals

1. Describe the course of the water cycle which formed in Biosphere 2
2. Deduce what would happen if you were to store your “Biosphere X” in the dark for a few weeks.
1) Solution
The sun warms the ocean surface and other surface water, causing liquid water to evaporate and ice to sublime. It turn directly from a solid to a gas. These sun driven processes move water into the atmosphere in the form of water vapor.
2) Solution
If we store the “Biosphere 2” in the dark for a few weeks, the water vapour will condense to form water.
What do the arrows indicate?
Air moves in a direction that creates land breezes.
Air above land warms faster than air above water.
Air blows over long distances in a continual straight path.
Air pressure remains the same while cycling over land and water.
The best answer would be:
The first option.
Air moves in a direction that creates land breezes.
If you'd like to know more about this, you can read on:
The arrows show how air moves as land breezes are created. In coastal areas, land cools much faster than water, so what happens is the air above it gets cooled down. When this happens, it becomes more dense moves downwards towards land. This causes high pressure and cause winds to blow outwards towards water (ocean).
Air moves in a direction that creates land breezes. Therefore, option (A) is correct.
What is land breeze?A land breeze is a type of wind that occurs at night and flows from land towards the nearby body of water, such as a lake or ocean. It is the result of temperature differences between the land and water surfaces during the nighttime hours. Land breezes are typically observed in coastal regions or areas near large bodies of water.
During the day, the land surface heats up more quickly than the water surface. As a result, the air above the land becomes warmer and rises, creating a region of low pressure. Meanwhile, the water retains its temperature more effectively, leading to a cooler air mass above the water and a region of high pressure. This temperature contrast sets the stage for the development of a land breeze.
As the sun sets and the land cools down faster than the water, the pressure gradient reverses. The air over the land becomes cooler and denser, forming a high-pressure area. Simultaneously, the warmer air over the water creates a low-pressure area. The pressure difference drives the wind to flow from the land towards the water, resulting in a land breeze.
Land breezes are typically characterized by gentle and steady winds blowing from the land towards the water. They are often observed during clear and calm nights when the temperature contrast between the land and water surfaces is significant. Land breezes can have localized effects, such as influencing local weather patterns and affecting coastal ecosystems.

A team of researchers are studying natural selection in a population of small marine invertebrates called isopods that live on pink corals. In this population, isopod body color is controlled by one gene with alternate alleles A and a. Isopods can be AA (red), Aa (pink), or aa (white). Isopod body size is controlled by another gene with alternate alleles B and b, and they can be large (BB or Bb) or small (bb). A new predator arrives on the reef that is extremely good at preying on isopods that are large and either red or white because they are easy to see. Over time, which genetic individuals have the best chance to become more abundant in the population with each subsequent generation?
Answer:
Pink and small Individuals with genotype Aabb will become more abundant in the population with each subsequent generation.

Explain how Sodium and Potassium exchange during active transport Write your answer in steps.
Answer:
Three sodium ions are extruded from and two potassium ions are imported into the cell.
Explanation:
Sodium-Potassium pump occurs during active transport in which sodium ions are removed and sent outside the cell while on the other hand, potassium ions are moved inside the cell due to their needs in the cell. Three sodium ions are moves outside the cell whereas two potassium ions are imported into the cell with the use of ATP molecules. The exchange occurs till the equilibrium of inside and outside environment can be achieved.

Why do identical twins have some DIFFERENCES?
A. The same genes are expressed because of their environment.
B. Different genes are expressed due to their environment.
C. Their DNA is different.
Answer:
B. Different genes are expressed due to their environment.
Explanation:
I think it's this one because it makes the most sense, but I'm still not sure sorry
Answer:
B. Different genes are expressed due to their environment.
Explanation:
Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.
