Compare the structures of the cat and chicken embryos in the images above. Which characteristics do the species share as embryos that they do not share when they are fully developed? Select all that may apply.
a) Both animals have tails as embryos
b) Both animals have similar upper limb buds as embryos
c) Both animals have feathers as embryos
d) Both animals have structures similar to gill arches as embryos
e) Both animals use their upper limbs for the same function
Answers
Both chicken and the cat begin with a tail, though eventually for the chick, it looses its long tail. Unlike the cat it keeps the tail it had when it was a fetus. That’s a shared characteristic embryo until they are fully developed.

You are curious about the dynamic instability of microtubules and decide to join a lab that works on microtubule polymerization. The people in the lab help you grow some microtubules using conditions that allow you to watch individual microtubules under a microscope. You can see the microtubules growing and shrinking, as you expect. The professor who runs the lab gets in a new piece of equipment, a laser beam that is very fine and can be used to sever microtubules. She is very excited and wants to sever growing microtubules at their middle, using the laser beam.
a. Do you predict that the newly exposed microtubule plus ends will grow or shrink? Explain your answer.
b. What do you expect would happen to the newly exposed plus ends if you were to grow the microtubules in the presence of an analog of GTP that cannot be hydrolyzed, and you then severed the microtubules in the middle with a laser beam?
Answers
Answer:
Follows are the explanation to the given points:
Explanation:
The polymerization of αβ-tubulin ligands costumes the microtubules. Among rising or reducing processes a microtubule may oscillate. Part of the carbon is a polar framework for two separate ends: a rapidly growing, most ending as well as a slow-growing less end.
In point a:
Severing a mitochondrial membrane throughout the media will create new "plus ends" or "minus ends." when mentioned in the question Then microtube is more prone to growth at most by adding GTP sub-units to some of the most open regions, where β-tubulin is activated. Even so, for some time GTP has also been hydrolyzed, keeping only one cap of the newly created, higher-end GTP-carrier subunits together with the remaining GDP-carrying cylindrical cap.
Consequently, a positive end is developed that consists of GDP subunits. Because the GDP sub-units become less strictly connected than that of the GTP sub-units, they eventually separate from one another. This allows a microtubule to be polymerized which causes the microtubule will shrink. But the newly exposed microtubule and sides will shrink if cut throughout the center.
In point b:
Well if the equivalent of GTP with such a microtubule is separated by laser from a non-hydrolyzable one, the newly exposed plus finish will include GTP carries. This GTP was NOT supplied with both the GDP kinase but would still expand the mitochondrial membrane. The unburned GTP plus microtubule will therefore continue to grow once it is cut in the center. The GTP equivalent is not hydrolyzable.
Which element is the basis for all living things and can combine with other elements in many ways?
phosphorus
carbon
oxygen
sulfur
Answers
Answer:
Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
Believe this ITS CARBON NOT OXYGENNNNN
Carbon is the basis for all living things and can combine with other elements in many ways. Hence, option B is correct.
What is the role of carbon in living organisms?Plants employ carbon to create their leaves and stems, which animals then eat and use for cellular growth. Gases like carbon dioxide are among the forms of carbon that are stored in the atmosphere. Additionally, many different marine species catch it and store it in the oceans.
Carbon serves as the fundamental building block for the majority of cells in the human body. The regulation of the body's physiology is another job for carbon. There are important biological activities that involve carbon in both plants and animals.
Thus, carbon is the basis for all living things and can combine with other elements in many ways. Hence, option B is correct.

Explain why methicillin resistant Staphlococcus aureus (MRSA) is more prevalent now than it was only 30 years ago. See Section 1.7 (Page) . Explain why methicillin resistant Staphlococcus aureus (MRSA) is more prevalent now than it was only 30 years ago. See Section 1.7 (Page) . Methicillin resistance causes an infection to spread more rapidly. Antibiotics cause mutations in Staphlococcus aureus that lead to an increase in the number of methicillin-resistant strains. Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus. Diseases like AIDS have made people more vulnerable to infections from Staphlococcus aureus.
Answers
Answer: Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus.
Explanation: The methicillin resistant Staphlococcus aureus is an example of the Theory of Evolution explained by Darwin. He stated that evolution is brought by 3 principles: Variation - the variety of species allows them to adapt better in the environment; Heridity - when those characterists necessary for survival passes on to the next generation; Natural Selection - the organism which is the most adapted to the environment survives to passes on their characteristics;
In a strain of Staphlococcus aureus, there are strains which are resistant to the antibiotics. The constant use of the medicament, and sometimes, the misuse of it, can select those strains which are resistant. As these characteristics are crucial for their survival, they are passed on to the next generation.
This is why the rate of methicillin-resistant Staphlococcus aureus has increased along the years.

Answers
Answer:
The mRNA leaves the nucleus and travels to the ribosome where proteins are synthesized
Explanation:
During transcription, a messenger RNA (mRNA) molecule is synthesized from a specific DNA region which is referred to as a gene. Subsequently, the mRNA leaves the cell nucleus through the nuclear pores of the nuclear membrane and travels to the ribosome, where this sequence serves as template to synthesize a protein, in a process known as translation. Within the ribosomes, triplets of consecutive RNA nucleotides called codons bind to complementary RNA nucleotides (called anticodons) of the transfer ribonucleic acids (tRNAs). Each tRNA attaches a specific amino acid that corresponds to its anticodon sequence, which is then added to the nascent polypeptide chain.
