Explain the mechanism of water movement from the roots up the tree to the leaves​

Answers

Answer 1

1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Answers

Answer: D: The distribution of many organisms has already shifted as a result of warming.

Explanation: I just took the quiz on FLVS

The statement that supports the biological predictions as it relates to change in climate is : ( D ) The distribution of many organisms has already shifted as a result of warming

What is climate change ?

Climate change is the long term change in the Average weather conditions of a region, province or territory. Climate change is associated to global warming caused by the activities of man which affects the weather conditions of a given region in the long term.  

As the climate continues to change, many organisms begin to redistribute themselves to regions with favourable weather conditions, and this is the biological prediction/effect of climate change on the environment.

Hence we can conclude that The distribution of many organisms has already shifted as a result of warming  is the correct statement.

12. Cows digest proteins into smaller molecules called peptides through the use of an enzyme called pepsin.
Aqueous solutions taken from the contents of a cow's stomach are found to have many more hydrogen ions
(H+) than hydroxide ions (OH-). A veterinarian is attempting to conduct an experiment that mimics protein
digestion and has the following four test tubes set up. Which would you expect to have the greatest
concentration of peptides?
(A) Test tube 1: protein and pepsin in water at pH 1.4
(B) Test tube 2: protein and pepsin in water at pH 8.2
(C) Test tube 3: protein in water at pH 7.6
(D) Test tube 4: pepsin in water at pH 1.7

Answers

The correct answer would be answer choice A!!!! The reasoning for this is that free H+ ions in a solution DECREASE the pH or in other words make the solution more acidic. So because of that we know that our solution must have a lower pH so we know the correct answer is either A or D because these are acidic solutions. In order for pepsin to catalyze the reaction there must be protein present and because of this we can eliminate answer choice D. So answer choice A is correct.

Plant cells have ribosomes only on the rough ER, while animal cells have ribosomes in the cytoplasm.
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles.
Plant cells have chloroplasts but no mitochondria, while animal cells have mitochondria.

Answers

Plants cells have a large central vacuole, while animals cells have many smaller vacuoles

Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

What are vacuole?

Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole.  The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.

Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.

Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.

Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.

Answers

Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.

The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.

Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.

The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.

should the INDEPENDENT
VARIABLE be placed?
A

B

Answers

Answer:

x-axis

Explanation:

you control those values/variables

On a cartesian plane, the independent variable belongs on the x-axis.

What are coordinates?

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

The independent variable is the variable that is being manipulated or controlled in an experiment, and its values are typically plotted along the horizontal or x-axis.

The dependent variable, which is the variable being measured or observed in response to changes in the independent variable, is usually plotted on the vertical or y-axis.

This convention allows us to easily visualize and analyze the relationship between the two variables.

therefore, The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
