HELP!!
What is the correct answer?

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.

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."            

Answer:

A reservoir of energy

Answer:

chemical battery and reservoir of energy

Explanation:

Answer: A desert is defined simply by the amount of rainfall that falls in an area in conjunction with the amount of evaporation. In essence, it's any area that receives on average less than 10 inches of rainfall per year, and where the yearly evaporation is more than 10 inches of rain a year.

Explanation:

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.

Answer:

The cell membrane help to maintaining homeostasis by regulating the flow of substances through it and by recognizing potentially harmful agents to the cell.

Explanation:

Cellular membrane is constituted by a lipidic bilayer, whose characteristics allow it to behave as a semi-permeable membrane to the passage of substances.

The selective permeability of the membrane makes it possible to regulate the passage of water, molecules and ions through it into the cell and from there into the extracellular space, a characteristic that allows the maintenance of homeostasis.

Additionally, the cell surface can identify foreign and potentially harmful agents, which can affect the internal balance, preventing in most cases their passage into the cell.

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.

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.

Answer:

B. Chemical - Cellular - Tissue - Organ - Organ System - Organism

Explanation:

The human body's hierarchical system that builds from smallest to largest units is : Chemical - Cellular - Tissue - Organ - Organ System - Organism.

Chemicals such as oxygen and carbon dioxide are the basic unit of the human body that forms atoms and biomolecules which further undergo chemical reaction to form cell or cellular, which is a basic unit of all life. Cells then form their functional groups called tissues and then different tissues form an organ. Different organs work together and form an organ system such as the digestive system and respiratory system. All the organ systems then form a living organism or human.

Hence, the correct option is "B. Chemical - Cellular - Tissue - Organ - Organ System - Organism".

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.

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.

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)

Answer: answer is down below

Explanation:

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.

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
