What is at the center of a red blood cell?
Plasma
Iron
Copper
Carbon
dioxide
Answer: Iron
Explanation:
hemoglobin: The iron-containing substance in RBCs that transports oxygen from the lungs to the rest of the body. It consists of a protein (globulin) and haem (a porphyrin ring with an atom of iron at its center).
Hope This Helps! :P
Answer:
Iron!
Explanation:
There is haemoglobin, an iron complex in the middle of a red blood cell, which helps the red blood cell carry oxygen around the body!
Hope that helps!

Will pigs ever fly?
Support your answer with suitable examples.
Answer:
NO
Explanation:
the pigs will never be able to fly as the birds have:
wings – these enable the force of lift.
lightweight, smooth feathers – this reduces the forces of weight and drag
streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)
light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight
Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.
Answer:yes they might
Explanation:
Birds are able to breed with pigs and pigs might get wings

Plants are living things and they need air, nutrients, water, and sunlight. Other living things are animals, and they need food, water, space, and shelter. Non-living things include things that do not need food, eat, reproduce, or breathe.
How does the energy produced by the sun travel to Earth?
o A. by the convection of heat through particles in space
B. by the magnetic fields between the sun and Earth
0 C. by the radiation of electromagnetic waves through space
D. by the process of conduction of heat between the sun and Earth
Explanation:
Energy is radiated from the sun, through the vacuum of space at the speed of light. When this energy arrives at Earth, some of it is transferred to the gases in our atmosphere.

Explanation:
How are hearing and touch alike and how are they
different?
Explanation:
They both are alike because they both rely on frequencies to determine perception. In hearing, a sounds frequency determines its pitch whereas in TOUCH the frequency of vibrations is used to perceive texture and to sense the environment through hand held tools.
In humans Attached earlobes (A) is dominant to unattached earlobes (a). Write all three possible genotypes and phenotypes below.
Answer: genotype Aa AA aa
Phenotype unattached earlobes, attached ear lobes
Explanation: genotype will be the combination of the genes. you have dominant (AA) recessive (aa) and heterozygous (Aa) the phenotype will be the expression from the genotype so for both dominant and heterozygous the phenotype is attached earlobes and for recessive the phenotype is unattached earlobes

what happens to a cell to specialize as a red blood cell
Answer:
Red blood cells transport oxygen around the body. They are specialised to carry oxygen because they: contain large quantities of a protein called haemoglobin , which can bind oxygen. don't have a nucleus, so there is more room for haemoglobin.

What type of organisms do scientist usually agree that birds are descended from?
A) reptiles
B) fish
C) amphibians
D) mammals
Answer:
A) reptiles
Explanation:
Many scientists are convinced that birds evolved from dinosaurs. Numerous finds in recent years have seemed to support the hypothesis that birds descended from two-legged, running dinosaurs called theropods. So, theropods are reptiles and the correct answer is reptiles.
which of the following is NOT a component that energy from the sun affects?
Answer:
No pictures .......But an educated Guess
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

Answer:
Whats the question
Explanation:
I don’t really get what you’re writing but,
They can’t really pinch together because of the cell wall, instead, a cell plate is laid down between the two nuclei. This structure develops into the new cell walls and cell membranes.

The offspring in binary fission are
identical
different
Answer:
Identical
Explanation:
Binary fission is a form of asexual reproduction. This is when only one parent is involved in creating offspring. Since there is only one parent, two sets of DNA cannot be combined into a new offspring; so, it must be identical.

Forces occur in action-reaction pairs.
A. 1st Law
B. 2nd Law
C. 3rd Law
Answer: C (3rd law)
Explanation:
Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out.
