Answer:
The correct answer would be A) ribosomes.
A ribosome is a vesicular structure present in both prokaryotic and eukaryotic cells. They consist of ribosomal RNA and associated proteins.
They are the site of translation in both prokaryotic and eukaryotic cells.
They are made up two units which are called large sub-unit and small sub-unit.
In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.
In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.
Answer:
The given blank can be filed with stasis.
Explanation:
There are various kinds of species that have been discovered in the world and had remained unmodified, that is, right from the start. This has been supported by their fossil records that in the geological strata they were witnessed unchanged. This phenomenon is termed as stasis, in which the species do not exhibit any kind of directional change. The starfish, lungfish, and the tribolates belong to this category, that is, their current time appearance is identical to the fossil records.
Right amount of water is the secret.
The answer is <span>b. Predation and mutualism.
</span>
<span>Mutualism is a relationship between two different species in which both species benefit. In clownfish - sea anemone relationship, the clownfish is protected from predators (butterfly fish) by the sea anemone, so the clownfish benefits from this relationship. The sea anemone gets more prey thanks to a coloration of the clownfish, so the sea anemone also benefits from this relationship. Since both species benefit, their relationship is an example of mutualism.</span>
<span>On the other hand, a relationship between the sea anemone and butterfly fish is an example of predation. Predation is the relationship in which predator hunts and feeds on its prey. In the example, the butterfly fish feeds on the sea anemone, so it must be predation.</span>
Answer:
Explanation:
It includes epidermis and cork. Epidermis : It is usually present in the outermost layer of the plant body such as leaves, flowers, stem and roots. Epidermis is one cell thick and is covered with cuticle. Cuticle is a water proof layer of a waxy substance
