pls help ill give brainlist!!!!!!!!!
Answer:
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance
Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself
Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.
A population of birds can have large, heavy beaks or thin, long beaks.
What can we say based on this data?
Select one:
We cannot conclude anything without having more data.
Having heavier beaks is a survival advantage.
Having longer beaks is a slight survival advantage, but having more data would help to confirm.
undo
There is no survival advantage between having heavier beaks and longer beaks.
Answer:
We cannot conclude anything without having more data.
Explanation:
All the statement says it that the birds have different types of beaks. There is no mention of information that the beak difference brings advantage or not. If the question were to say the heavy beaks survive more, then the answer would be those birds have an advantage- because it does not, the answer is we need more data

Which of the following cell membranes is the most fluid?
Membrane A, because it is composed of saturated fatty acids that have one or more cis bonds that form stable aggregations
Membrane A, because it is composed of saturated fatty acids that lack weak hydrogen bonds that continually break and reform to permit macromolecule movement
Membrane B, because is it composed of unsaturated fatty acids that form weak covalent bonds at the site of their cis bonds, which permit easy movement
Membrane B, because it is composed of unsaturated fatty acids that have one or more bends, which prevent tight packing
Answer:
Membrane B, because it is composed of unsaturated fatty acids that have one or more bends, which prevent tight packing.

As compared to the circulatory system of most fishes, the circulatory system of adult amphibians has the advantage of a single circuit. partially-separate circuits for gas exchange and systemic delivery of blood. complete separation between oxygenated and deoxygenated blood. a four-chambered heart. a pocket of the gut that serves as an air bladder.
Answer:
Partially separate circuits for gas exchange and systemic delivery of blood.
Explanation:
Adult amphibians have separate circuits for gas exchange and systemic delivery of blood. Fishes usually breathe through gills and very few have nostrils. The fishes can breathe underwater with the help of their gills.

Can someone please help me I don't understand what I have to do.
Answer:
all you're trying to do is create a histogram of what has happened in the past and what could happen in the future.
Explanation:
for example and AD you feel the first little bar because it's not more than a billion and its last therefore it would be the zero billion
and then for 1850 you feel to bars because they had 1 billion people so therefore you feel the 0 billion and the 1 billion part

Which of the following describes a scenario that could increase the winds of the jet stream?
O Faster global convection currents
O Decreasing radiation from the sun
O Equal heating of the Earth's surface
O Stopping conduction from the ground
Answer:
faster global convection currents!
Fortunately I just took this quiz and received 100%!
The statement that explains scenerio that can bring an increase to winds of the jet stream is A: Faster global convection currents.
Jet streams can be regarded as a fast flowing as well as narrow and meandering, air currents which is found on Earth and other planet. It is a bands of strong wind which moves to east from west in the globe.The wind of jet stream do increase by the action of wind current, because convection current do aid the movement of this this wind from a place to the otherTherefore, option A is correct.

explain how bacteria cam develop resistance to an antibiotic?
Explanation:
Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs become resistant.

1. alveoli, tiny air sacs within the lungs muscle below the lungs used for, 2. bronchi, breathing the two tubes into which the, 3. diaphragm, trachea divides before entering the lung
Answer:
1. Alveoli: tiny air sacs within the lungs.
2. Bronchi: the two tubes into which the trachea divides before entering the lung.
3. Diaphragm: a muscle below the lungs used for breathing.
Explanation:
Living system can be defined as the internal systems of organisms and how materials circulate within organisms.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, metabolism, digestion, etc.
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
1. Alveoli: it comprises tiny air sacs and it's located within the lungs of living organisms.
2. Bronchi: these are the two (2) tubes into which the trachea divides (the right bronchus and the left bronchus) before entering the lung.
3. Diaphragm: it's a muscle located below the lungs and typically used for breathing in all living organisms.
