The correct answer is: The nuclear envelope is continuous with the endoplasmic reticulum
The nuclear envelope or nuclear membrane is composed of two phospholipid bilayers (outer and inner) that surround the nucleus in the eukaryotic cell. The space between the outer and inner membranes is called the perinuclear space. The nuclear envelop has nuclear pores that are responsible for the transport between nucleus and cytoplasm (e.g. transport of mRNA).
Answer:
Explanation:
Membrane bound organelles and eukaryotic
So let’s substitute that into the
third equation and solve for B. B = H + T B = 9 + (9 + 1/2B) B = 18 + 1/2B Then
subtract 1/2B from both sides: 1/2B = 18 Multiply both sides by two: B = 36 Now
we know the value of B and the value of H. Substitute this back into the second
equation and solve for T. T = H + 1/2B T = 9 + (1/2)36 T = 9 + 18 = 27 Step 4:
Plug all values of H, T, and B into the final equation. Total length of fish =
H + T + B Total length of fish = 9 +27 + 36 = 72.
Answer:
Both biotic and abiotic factors affect the survival and reproductive success rate of fishes in an ecosystem.
The number of predators that a particular type of fish will have will influence the survival and reproductive rate of that fish. An increased number of predators will mean that the fishes will not be able to survive in that ecosystem and will be eaten up.
The number of preys will also affect the survival rate of fishes in an environment. The lesser the number of preys, the more the competition for food among species.
Abiotic factors like the concentration of salts in water will also influence the survival and reproduction of fishes. If a fish is not adapted to live in saline water conditions, then accumulation of salts in the ecosystem might destroy the whole fish species in that ecosystem.
Human activities, like the throwing of wastes into the aquatic ecosystem, drainage of fertilizers in the aquatic system can also destroy the survival and reproduction rate of a particular kind of aquatic animal species.
Explanation:
<span>The cells all have different qualities.
A plant cell will have a cell wall (the others don't have these) and so it will be kept in a rigid shape, unlike the others which are free to be blobby. Inside a plant cell, there is also a vacuole containing cell sap. The others don't have this. Plant cells also have chloroplasts, which look similar to mitochondria on a diagram. Chloroplasts contain chlorophyll, and this is used for photosynthesis. </span><span>
