Answer:
A
Explanation:
The two strongest bonds are ionic and covalent, but generally, ionic is viewed as the stronger bond because of the ion-ion force that occurs within the bond. It does depend on other factors though.
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!

plants are living things true or false
Answer:
True
Explanation:
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.
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.
Explanation:
Anything other than this^^^^^ is wrong.

Explanation:
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

Homologous structures are defined as anatomical structures originating from the
same structure in ancestral form. For instance, a bird's wing and the front flippers of
a seal are examples of homologous structures. Which of the following does the
presence of homologous structures in vertebrates suggest?
Explanation:
An example of homologous structures in vertebrates is
where the wings of bats, front flippers of whales, and forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.
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.
Some factories have started using large tanks of bacteria to remove carbon dioxide from the atmosphere. As more factories start to do this, the amount of carbon dioxide in the atmosphere could decrease over time. If this happens, and if energy coming from the sun and the amount of carbon dioxide being put into the atmosphere otherwise stay the same, what would happen to the total amount of energy in the Earth system and to global average temperature
Answer:
The carbon dioxide in the atmosphere will be reduced if more factories started using bacteria to capture carbon dioxide
Explanation:
There will be more that will reach the Earth System than exited as combustion introduced carbon dioxide to the atmosphere, so the total amount of energy in the system will increase.
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.

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.
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.
what is the geological carbon cycle
Answer:
Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins.
Explanation:
Why do asexually reproducing organisms not benefit from recombination? Explain.
Answer:
Explanation:
While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.The key difference between sexual and asexual reproduction is that sexual reproduction involves two parents of the opposite sex while asexual reproduction involves a single parent.
The ability to reproduce and produce a new generation of the same species is one of the fundamental characteristics of a living organism. It involves the transmission of the genetic material from the parental generation to the offspring generation, ensuring the characteristics of the species and perpetuating the characteristics of parental organisms. Before a new individual reaches its own reproductive stage, it normally has to go through a period of growth and development. Some members of the species will die before they reach reproductive age due to predation, disease and accidental death. So the remaining species will only able to produce more offspring and contribute to the continuation of the species. There are two basic types of reproduction; namely, asexual and sexual reproduction.
Answer:
Recombination only occurs when 1/2 of the strand from each parent is used, in which parts of the strand may be used to create the new strand. Asexually reproducing organisms don't benefit rom recombination, because frankly there is no other strand in which recombination can be used. Instead, the most the recombination can occur is within it's own strand, which means that essentially there is less combinations then if two strands are used. As such, asexually reproducing organisms would look more or less the same.

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.
how are electromagnetic waves and mechanical waves the same?
bots get mass reported, no bad answers bad answers get reported, you get brainlyest if you answer first
Answer:
Both electromagnetic and mechanical waves are the movement of energy. They can be measured in the same ways too. The amplitude, frequency, and wavelength are ways to represent the measurements of waves. Additionally, they both have crests and troughs. Finally, both can be reflected, absorbed, or transmitted.

What must the pea and lettuce plants take up through their roots to perform photosynthesis
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.
Explanation:
