Answer:
it contains iron that gives it the red color when exposed to oxygen
Human blood-red and not blue because Hemoglobin contains iron that gives the blood the red color when exposed to oxygen. The correct option is c.
What is hemoglobin?Hemoglobin is a red color pigment that is present in the blood. It contains a heme group that carries oxygen into the body and carries carbon dioxide outside the blood. It is red and in some animals, it is blue because of copper.
Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin. In turn, our blood is red because of the millions of red blood cells that it contains.
Therefore, the correct option is c. Hemoglobin contains iron that gives the blood a red color when exposed to oxygen.

Answer:
All of our energy and nutrition come by way of the gastrointestinal (GI) tract. It is an amazing machine well designed for digesting and absorbing nutrients and for shielding the rest of the body from microorganisms, viruses and other foreign matter. The GI tract spans from the mouth to the anus, with each separate organ having a role in digestion, absorption or excretion.Lastly, if you would like to learn more about yourself and how you can best reach your own nutritional and fitness goals, we encourage you to take a look at the following home health testing guides and resources:

The connective tissue layer that surrounds an entire muscle is called ______. Multiple choice question. epimysium endomysium perimysium
Answer:
the answer is epimysium
Explanation:
The connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option as it is composed of dense, irregular connective tissue and serves to protect the muscle.
What is epimysium?The epimysium plays a role in transmitting force from the muscle to the surrounding structures and connects to the tendons and other connective tissues that attach the muscle to bone and other structures, and the epimysium is just one of the three connective tissue layers that make up the structure of a skeletal muscle; the other two layers are the perimysium and the endomysium, and together, these three layers of connective tissue provide the necessary structural support for skeletal muscles to function properly.
Hence, the connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option.

Cellular organelles have different structures. Mitochondria, for example, possess highly folded inner membranes in addition to their outer membranes. Vacuoles, on the other hand, are only surrounded by a single-layer membrane; they do not have an inner membrane.
Why do cellular organelles have different structures?
A.
Organelles that are less important to the cell have less sophisticated structures.
B.
All of the organelles in a particular organism are identical, but organelles in different organisms are unique.
C.
The structure of a cellular organelle mimics the appearance of the organism.
D.
The structures of cellular organelles are related to their functions.
Answer:
D
Explanation:
Different oganelles do their own function.
The structures of organelles differ because the structures of organelles are related to their functions.
What are the functions of cell organelles?An organelle is a subcellular structure that has one or more specific functions in a cell, such as an organelle in the body. The most important cell organelles are the nuclei, which store genetic information.
Organelles are small structures in the cytoplasm that perform functions necessary to maintain homeostasis in the cell. They are involved in many processes, such as energy production, the formation of proteins and secretions, the destruction of toxins, and responding to external signals.
Examples of membrane-bound organelles include the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes, and vacuoles.

will you be able to synthesize both strand of the dna helix in a continuous manner?
Answer:
No.
Explanation:
There are two strands in DNA -i)Leading strand
ii)lagging strand.
Replication of the leading DNA strand is continuous, while replication along the lagging strand is discontinuous. After a short length of the DNA has been unwound, synthesis must proceed in the 5' to 3' direction; that is, in the direction opposite that of the unwinding.
No, we will not be able to synthesize both strand of the dna helix in a continuous manner because the lagging strand synthesize in a discontinuous manner.
What is the process of DNA synthesize?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological inheritance.
Continuous DNA synthesis takes place on the leading strand. As the helix unwinds, DNA synthesis on the lagging strand restarts numerous times, resulting in numerous brief pieces known as "Okazaki fragments," which are then joined by DNA ligase to form a single DNA molecule.

Which of the following is associated with plates moving away from each other? a. Rifts b. Subduction zones c. Faults d. All of the above.
Answer:
a. Rifts
Explanation:
A fault (c) happens at all plate boundaries, so while this is true, it is not the most correct. A subudction zone (b) is where Earth's tectonic plates dive down into the mantle, so this does not answer our question. A rift, in general, is a crack, split, or break in something. A rift in plate tectonics is when plates are moving apart from each other, caused be tension, so a is our answer.

The human brain communicates with the rest of the body through networks of what?
Through nerves attached to the brain and to the spinal cord. When an action potential traveling down the axon reaches a terminal button, they secrete a chemical called a neurotransmitter.
The brain communicates with the rest of the body through the spinal cord, which runs from the base of the brain all the way down the back. The spinal cord is made up of lots of nerves, and these nerves branch out into more nerves that travel to every part of the body.

DNA is coded to RNA, which must travel from the nucleus to the cytoplasm to be read. Why does the cell need to transcribe the DNA into RNA rather than copying the DNA directly?(1 point)
DNA requires too much energy to code; building RNA is more efficient.
DNA cannot be copied; it must be translated to RNA and then back to DNA.
DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.
DNA cannot be read by ribosomes; they can only read RNA.
Answer:DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.
Explanation:
DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded. DNA could get damaged because of the osmotic nature of cytoplasm. Therefore, option (C) is correct to mitigate he damage.
What is transcription?The proteins are produced by cells by the transcription and translation of certain genes from their DNA into molecules of messenger RNA (mRNA), chains of amino acids, and finally fully functioning proteins.
The DNA would need to go to the cytoplasm in order to directly make proteins. Because of the osmotic properties of cytoplasm, DNA may become damaged during the translocation process. The cellular machinery does not directly make proteins from DNA in order to reduce the harm.

why did the early atmosphere not have much oxygen?
Answer:
The oxygen did not build up in the atmosphere for a long time, since it was absorbed by rocks that could be easily oxidized (rusted). To this day, most of the oxygen produced over time is locked up in the ancient "banded rock" and "red bed" rock formations found in ancient sedimentary rock.

HELLLP!!!!! Seeds are one way that plants reproduce. What are the reproductive advantages of using seeds to reproduce? What are the two major divisions of seed plants, and how do plants in each of these divisions reproduce?\
Explanation:
1-Seeds provide a protective coat so that the embryo plant can develop when it finds a nice piece of soil.
2-Vascular plants are subdivided into two classes: seedless plants, which probably evolved first (including lycophytes and pterophytes), and seed plants. Seed-producing plants include gymnosperms, which produce “naked” seeds, and angiosperms, which reproduce by flowering.
