Knowing what you know about how a substance travels in diffusion, in
order for oxygen to leave the alveoli and enter the blood, there would be
concentration of oxygen in the alveoli compared to the
blood. *
A.higher
B.Lower
Answer:
the oxygen should be concentrated in the alveoli
Explanation:
Diffusion: The movement of molecules from a region og higher concentration to a region of lower concentration.
So when the Oxygen is concentrated in the alveoli only then it can move towards the blood
Diffusion is a passive transport system which means it doesnt need energy in the form of atp molecules
if the molecules move from a region of lower concentration to a region of higher concentration it needs atp molecules which is energy and is called active transport system
The answer should be "HIGHER."
A person is admited into the hospital an unknown ailment. The patient is seen by Triage and immediately put on intravenous liquid or more commonly known as an IV by a brand new nurse

What will mostly likely occur to this patient’s red blood cells if the IV dispenses its contents in its totality?
A) The environment in the patient’s blood will be isotonic if the cells and their environment have reached equilibrium, cells will remain the same size.
B) The environment inside and outside the patient’s cells will be isotonic and may cause the cells to burst.
C) The environment around the patients cells will be hypotonic and cause the cells to shrink.
D) The environment inside the patient’s cells will be hypertonic and may cause the cells to burst.

Which of the following is the most likely reason the Moon can NOT support life?
А
It has many craters, indicating that it has an atmosphere too weak to protect life
B
It has many craters, indicating that is has a magnetic field too powerful for life.
С
It has many dark spots, indicating volcanic activity too extreme for life.
D
It has many light spots, indicating frozen ice that is too cold for life.
Answer:
A
Explanation:
B is not true because the amount of craters does not indicate how powerful the magnetic field is, it indicates how much gravity there is.
C is not true because the dark spots are igneous rock, dried lava. That means that there WAS volcanic activity, in the past.
D is not true because the light spots on the moon are not ice, they are simply a lighter colored rock.
A is true because meteors will burn up in the atmosphere of planets because of friction, so not all the meteors will hit said planet. But if there isn't an atmosphere, all of the meteors will hit that planet. (or in this case, moon)

Which correctly lists the three features of Earth that are the main types of landforms?
A. hills, valleys, and plateaus
B. lakes, valleys, and mountains
C. mountains, plains, and plateaus
D. plains, lakes, and hills
Answer:
c
Explanation:
because it has all the types of features of earth
They even impact which military sites are most effective at defending a given area. Thus, option C is correct.
What different landforms on earth that affect function?The four main types of landforms are mountains, hills, plateaus, and plains. Buttes, canyons, valleys, and basins are examples of minor landforms. Mountains and hills can be pushed upward by tectonic plate movement under the Earth.
The various natural sceneries on the world are produced by landforms. They serve as homes for both animals and people. A place's topography is composed of its landforms.
All people's lives depend heavily on landforms. They have an impact on a region's cultural history, societal development, food production, housing options, and architectural and building choices.
Therefore, because it has all the types of features of earth.

Tina-Marie accidentally left her water bottle outside on a freezing, winter night. The next day, the water bottle, which is now filled with ice, ruptured. Based on her observations, Tina-Marie forms a hypothesis about freezing water and volume. Identify a hypothesis Tina-Marie can investigate. Then describe an experimental procedure for investigating the hypothesis.
Answer:
Hypothesis, Ice is less dense then water.
Explanation:
They could test this by attaining the density of ice and water, the density of Water is 1g/ml and if the ice floats that means ice is less then 1 g/ml which means ice is less dense. This is relevant to the water bottle because the Ice expanded due to it being less dense causing the water bottle to rupture
What is a small ecosystem in danger of compared to a large and diverse ecosystem?
Answer:
See the answer below
Explanation:
A small ecosystem is in danger when compared to a large and diverse ecosystem because the genetic variability in a small ecosystem is low and a small disruption can wipe out the populations within the ecosystem. This is unlike in a large ecosystem where this is a high genetic variability that gives the populations within the ecosystem resilience against disturbances.
There are enough alleles within the genetic pool of a large and diverse ecosystem to withstand disturbance regimes unlike in small ecosystems where the alleles are few. Hence, a little disturbance can endanger the entire population in a small ecosystem and put them at the risks of extinction.
What are genetic variations? First answer gets brainliest! Please help
Answer:
Genetic variation refers to differences in the genetic makeup of individuals in a population. Genetic variation is necessary in natural selection. In natural selection, organisms with environmentally selected traits are better able to adapt to the environment and pass on their genes.

What is the blending theory of inheritance? Why did Mendel question this theory?
Answer:
Blending Theory of Inheritance
Mendel noticed plants in his own garden that weren't a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory
The blending theory state that the inheritance of traits from two parents produces offspring with characteristics that are combination of the parents.
What is blending theory of inheritance?Blending theory of inheritance stated that, offspring is combination of characteristics of the traits from two parents. Blending inheritance was discarded after the general acceptance of the modern genetics.
Mendel noticed that plant in his garden were not blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height.
Therefore, Mendel question this theory. He wanted to know if there was different principle that could explain how the characteristics are inherited to the offspring from parents.

Compare and contrast Meiosis and Mitosis, how are they similar and how are they different?
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Answer:
1. meiosis require two nuclear division but mitosis requires only one nuclear division
2. meiosis produces four daughter divisions, and there are four daughters cell following cytokinesis. Mitosis followed by cytokinesis result in two daughter cells
3. in meiosis, the four daughter cells are haploid and have half the chromosome number as the parent cell. In mitosis, the daughter cell have the same chromosome number as the parent cell
4. in meiosis the daughter are genetically dissimilar to each other and to parent but in mitosis, the daughter cells are genetically identical to each other and to the parent.
