Answer:
The embryo develops the heart, nervous system and face.
Explanation:
The nervous system is one of the first things to develop, following is the heart and then their face. Physical traits which also develop are the arms, legs and sexual organs.
Answer:
los alimentos están compuestos principalmente por cuatro moléculas básicas -todas ellas consideradas macronutrientes- como son; el agua, las proteínas, los hidratos de carbono y los lípidos, sustancias que al ser cocinadas experimentan una serie de cambios, creando las estructuras y texturas de nuestras
Answer/Explanation:
First, initiator protein unwinds a short stretch of the DNA double helix. <u>The length of the DNA double helix about to be copied must be unwound. </u> In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases. Once the DNA strands have been unwound, they must be held apart to expose the bases so that new nucleotide partners can hydrogen-bond to them. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
B) Endocrine disruptors mimic hormones that regulate critical biological processes
<u>Answer</u>:
Inhibition of host protein synthesis would not be a potential side effect of standard antimicrobial drugs.
<u>Explanation</u>:
Antimicrobial drugs that are specific to inhibit the protein synthesis only target the units of 70S ribosomes. Hence, the ribosomes of eukaryotes remain unaffected. The microbiota present in digestive system is prokaryotic and gets affected by the antibiotics.
Antibiotics can damage the renal tubular cell of the kidney on long term use. As the excretion of toxic drug bi-products and other metabolites takes place from the kidney hence it is highly exposed to these end products.
For example, aminoglycosides have been shown to be nephrotoxic (damaging to kidney), Allergy reactions such as hypersensitivity reactions and anaphylactic reactions such as asthma, coughing, hives are the other side effects of antimicrobial drugs because the cells of immune system recognize these drugs as foreign molecules and attacks them which causes the allergy reactions.
