Answer:
Endoplasmic reticulum: Sac filled with digestive chemicals
Ribosomes: Small structure that synthesizes proteins
Golgi body ( Golgi apparatus): Stack of membranes that packages chemicals
Lysosome: Structure that manufactures ribosomes
Mitochondria: Structures that converts nutrients to energy
Cell membrane: Membrane that surrounds and protects the cell.
Explanation:
I'm learning this too in school so I know this is right!
Answer:
Because the have similar limbs.
Because they have similar functions.
Explanation:
(because they have similar limbs)
Homology (evolution) describes a structure that has similar function like limbs on dogs and bears (used for walking) and also have a similar arrangement of bones. The fins on a doplhin might be different from the wings on a bat but they reflect a common origin due to their bone composition e.g carpals and radius bones.
(because they have similar functions)
Analogy (evolution) describes a structure with for example, bird and butterfly wings that have no common ancestor but have the same purpose, in this case flying. They developed independtly as adaptions. This supports natural selection which is a driving force for evolution.
<h2>Answer:</h2><h3>Be skeptical of the results.
</h3><h2>Explanation:</h2>
Scientific skepticism is the method or plan of investigating paranormal and pseudoscientific applications by the spectacles of science and significant research and then bestowing the results with the people. ... "Skepticism is a temporary access to applications.
The purpose of the experimental procedure is to gain factual information regarding the test so that there is no guesswork involved in the result. And as such errors can exist in the experiment or the way it is carried out.
They are genetically and reproductively isolated. For the mule the specific isolation mechanism is termed as "Hybrid Inviability", where the postzygotic isolating mechanism prevents the hybrid from passing on their genes. A zygote may form with the sperm and egg, but the embryo will dies after a few cell divisions. The genetic information from male and female parents is insufficient to carry the organism through morphogenesis. *There are rare documented cases of a mule producing a viable offspring.
Answer:
The functional groups that define the two different ends of a single strand of nucleic acids are:
B. a free hydroxyl group on the 5' carbon a free hydroxyl group on the 3' carbon
G. a free phosphate group on the 5' carbon
Explanation:
A nucleic acid is a polymer formed of nucleotides that are linked with a phosphodiester bond. The structure of a nucleotide consists on a phosphate group linked to a pentose (ribose in RNA and deoxyribose in DNA) that is also attached to a nitrogenous base. The nitrogenous bases are adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA).
DNA and RNA are nucleic acids which can be found in a double or single strand presentation.
Nucleic acids are synthesize in the 5’ to 3’ direction, so that is why the convention is that the sequences are written and read in that direction.
The strand of a nucleic acid is directional with an end-to-end orientation, where the 5’ end has a free hydroxyl or phosphate group on the 5' carbon of the terminal pentose, and the 3’ end has a free hydroxyl group on the 3’ carbon on the terminal pentose (ribose/ deoxyribose).
