Reptiles' capacity to deposit amniotic eggs is the main trait that enables them to live exclusively on land. Amniotic eggs have a protective shell around them and include specific membranes that give the growing embryo a self-contained aquatic environment. Amniotic reproduction is the name given to this adaptation.
The amniotic egg has a number of crucial characteristics that let it thrive on land. These qualities consist of:
Shell: By minimizing water loss, the embryo's shell protects it physically and keeps it from desiccating (drying out).
Amnion: The amnion is a membrane that covers the embryo and holds amniotic fluid, which acts as a cushion and source of buoyancy.
The chorion is an additional membrane that encircles the amnion. By facilitating gas exchange, it allows carbon dioxide to leave and oxygen to enter the egg.
The allantois is a sac-like organ that aids in breathing and stores metabolic waste products from the developing embryo.
Egg yolk sac: The yolk sac is a source of proteins, lipids, and minerals that feed the growing embryo.

Which best represents a balanced equation
Answer:
option C is correct answer of this question
hope it helps
it is balanced equation
The example of a balanced chemical equation is 2H₂ + O₂ → 2H₂O. Thus, the correct option is C.
What is a balanced equation?A chemical equation is the symbolic representation of the chemical reaction in the form of symbols and chemical formulas such as H₂O. Chemical equation are generally are unbalanced however, these reactions can be balanced.
Balancing a chemical equation refers to balancing the stoichiometric coefficients on both the reactants and products side of the reaction which is because the chemical equation must obey the law of conservation of mass of the atoms.
2H₂ + O₂ → 2H₂O
This reaction has 4 H and 2 O atoms.
Therefore, the correct option is C.

Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.

Sally, 9-year-old girl, just did an awesome backflip on her trampoline. Instead of landing in a similarly awesome manner, she miscalculated and landed on her neck. Sally stood up with pain in her neck and does not appear to be able to extend her left arm very well. An x-ray shows a fracture of her C6 vertebrae that is compressing down on her C7 vertebrae impacting the spinal nerve located between C6 and C7 vertebrae. Which spinal nerve did Sally likely injure
Answer:
The C7 spinal nerve
Explanation:
The C7 spinal nerve exits on each side through the intervertebral foramen between the C6 and C7 vertebrae. The C7 spinal nerve has both a sensory root which is composed of sensory fibers and a motor root. This nerve is required to control motor functions including shoulder movement (i.e., adduction, abduction and rotation). The C7 dermatome is a region of skin that receives sensory inputs from the C7 spinal nerve.

The role of the RNA-induced silencing complex (RISC) in RNA interference is to cleave tRNAs to slow the rate of translation. disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced. cleave the introduced RNA duplex. disrupt gene expression by interfering with mRNA export to the cytoplasm. create a passenger strand to bind to the mRNA and keep the mRNA from being translated.
Answer:
disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced
Explanation:
The RNA-induced silencing complex (RISC) is a ribonucleoprotein complex composed of proteins that associate with regulatory small non-coding RNAs (sncRNAs) such as, for example, microRNAs (miRNAs) and small interfering RNAs (siRNAs) in order to regulate gene expression by the RNA interference (RNAi) pathway. These sncRNAs (around 18-30 nucleotides in length) are complementary or nearly complementary to messenger RNAs, thereby they can bind to target mRNA sequences in order to trigger RNAi via mRNA degradation, translational repression, etc. The core component of the RISC complex is an evolutionary conserved Argonaute (Ago) protein that cleaves target mRNAs.
mendels law of independent assortment
Answer:
Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. Let's look at a concrete example of the law of independent assortment.
