Answer:

Transcription makes RNA from DNA, translation turns RNA into proteins.

Explanation:

Transcription is the first stage in gene expression in which an RNA molecule is made by copying a gene's DNA sequence. Transcription is carried out by the enzyme RNA polymerase which joins nucleotides together to make an RNA strand, while translation is also a process in gene expression in which messenger RNA (mRNA) is decoded within a ribosome to build a chain of  amino acids which later folds to form an active protein. Translation occurs after the process of transcription.

UNO [17]

Answer:

1000 mM

Explanation:

Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM

So, V = -60 mV㏒₁₀[K/K']

-60  mV = -60 mV㏒₁₀[K/K']

dividing both sides by -60mV, we have

-60  mV/-60 mV = ㏒₁₀[K/K']

㏒₁₀[K/K'] = 1

taking antilogarithm of both sides, we have

[K/K']  = 10¹

multiplying both sides by K', we have

K = 10K'

K = 10 × 100 mM

K = 1000 mM

So, the intracellular Cl- concentration is 1000 mM

Aloiza [94]

Answer:

The correct answer is " two cardiac muscle cells are connected by gap junctions".

Explanation:

Intercalated discs are microscopic features seen in the microscope as cardiac fibers, found between the myocardial cells of the heart. These features correspond of two cardiac muscle cells connected by gap junctions. The intercalated discs allow the interconnection of multiple cardiac cell muscles to work simultaneously as a single functional organ or syncytium.

Answer:

pushing iron out

Explanation:

Excess iron will be push out of the cell to regulate the internal environment of cell, this active transport involve osmosis.

if this type of reaction occur in a plant cell, the plant cell will shrink which may/will leads to death of the plant.

Hope it is helpful

don't mind my grammatical blunders.

Thank you.

Why are so many eggs produced by invertebrates?
klasskru [66]
An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.

Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.
