What is a common source of proteins within the body (not from food)?
Answer:
I hope this helps
Explanation:
When a cell needs to make proteins, it looks for ribosomes. Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains. Ribosomes are special because they are found in both prokaryotes and eukaryotes.
If the offspring of the cross showed ccdominance, what would the eyes of the offsping look like?
Answer.. the offspring would have one circle eye and one star eye.
Answer:
That is what I would choose
Explanation:
When two different phenotypes of an organism are crossed, a third phenotype is created in which both of the parental traits are present. This is known as codominance.
What are the results of codominance cross?The concept of codominance states that although both phenotypes are dominant, they cannot coexist. Codominance would result in patches rather than merging, with areas of prominent white expression and areas of dominant red expression.
The statements made about codominance are all accurate. The full expression of both alleles is present.
The distinct results of both alleles are present in the heterozygous phenotype. A multiple-allele characteristic has (less than / only / more than) two alleles in the corresponding gene.
Therefore, The offspring would have one circle eye and one-star eye.

Polymer Monomer
1. Polypeptide/protein -----------------------→ Amino acid
2. Polysaccharide ------------------------------→ Monosaccharide
3. Nucleic acid -----------------------------------→ Nucleotide
4. Lipid ----------------------------------------------→ Fatty acid
Explanation:
Monomers are simple molecules that when joined together and form chains become polymers, a process called polymerization, which is mediated by polymerase enzymes.
Monomers are simple molecules that when joined together and form chains become polymers, a process called polymerization, which is mediated by polymerase enzymes.
Peptides and proteins are formed by the addition of specific amino acid sequences. Polysaccharides, or complex sugars, are formed by the addition of monosaccharides, such as glucose. A nucleic acid, such as DNA or RNA, consists of chains or strands that are formed by nucleotide sequences. Lipids are the polymerized form of fatty acids.Is water abiotic or biotic?
Answer:Abiotic
Explanation:
There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.

The purpose of an experiment is to test the hypothesis. Hypotheses are formed based on observations, and an experiment is designed to see if the hypothesis is right.
Francine is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below. Her friend Byron evaluates the model, and suggests that she thicken the arrow leading from fossil fuels to the atmosphere. His reasoning is that fossil fuels are being burned at a much faster rate than natural processes are restoring them. If Francine adopts Byron’s suggestion, how could her model be used to explain a significant change to Earth's systems?
Answer:
After adopting the suggestions of Byron the new or revised model would show that using fossil fuels at a rapid rate would lead to higher inputs of carbon dioxide to the atmosphere which will not be removed by the natural process of removing the excess amount of the carbon dioxide by the process of the photosynthesis and other.
The carbon dioxide would increase due to this and cause trapping of the solar heat in the atmosphere which leads to the greenhouse effect to warm the earth. That ultimately changes the climate of the earth.

In the fluid mosaic model, where would you most likely find the transport proteins?
Attached to the outer portion of the phospholipid bilayer
Embedded within the hydrophobic and hydrophilic regions of the bilayer
Flipping, alternating between the hydrophobic and hydrophilic regions of the bilayer
Roaming within the phospholipid bilayer
thanks so much
Answer:
B: Embedded within the hydrophobic and hydrophillic regions of the bi layer
Explanation:
They are integral protiens and have to be inside
i took a test
This movement aids the cell membrane in preserving its function as a partition separating the interior and exterior cell surroundings. Thus option B is correct.
What is the role of transport protein in fluid mosaic model?Integral proteins protrude from each end of the phospholipid bilayer and are tucked inside. Larger molecules like glucose can be transported through cell membranes with the aid of integral proteins.
They have sections that match the polarity of the phospholipid bilayer, known as "polar" and "nonpolar" regions.
This movement aids the cell membrane in preserving its function as a partition separating the inside from the outside environments of the cell.
Therefore, in the fluid mosaic model, the transport protein is connected to the phospholipid bilayer's outer layer.

List five organelles eukaryotes have that prokaryotes do not have. ( 5pts)
Answer:
Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria, and Cytoskeleton
Explanation:
The characteristics that eukaryotes have are lysosomes, mitochondria, nucleus, ribosomes, and endoplasmic reticulum.
What are eukaryotes?Eukaryotes are lifeforms with nuclei and other membrane-bound organelles. Eukaryotic organisms include all animals, plants, fungi, and protists, as well as the majority of algae.
Prokaryotic organisms are the ones lacking a well developed nucleus. They do not possess lysosomes, mitochondria, nucleus, ribosomes, and endoplasmic reticulum.
Thus, these are five organelles that are present in eukaryotes but are absent in prokaryotes.
