Answer:
The sea urchin population expanded and consumed the kelp and damaged the habitat.
Explanation:
Sea otters prey on sea urchin and keep their population under control. Without sea otters, the sea urchin population cannot be kept in check and they will over consume kelp.
Devastating effects resulted from the excessive sea otter hunting around the Pacific Coast. Because sea otters are a keystone species in the ocean, they have an outsized impact on their surroundings. They eat kelp forests, which in turn eat sea urchins.
What happened without the sea otters ?Without sea otters to control their numbers, the sea urchin population grew and ate up the kelp, harming the environment. Fish depended on the kelp forests for cover, hence this led to a drop in the fish population. The sea otter species came dangerously close to extinction as a result of the rapid population fall.
The government has designated sea otters as a species of special concern in the United States, so this was very alarming.done action to safeguard them. The Pacific Coast environment was affected by the sea otter population collapse, which also had an impact on the fish population and kelp forests.
The overhunting of sea otters has led to the implementation of many conservation initiatives. Reintroducing sea otters to the Pacific Coast is one such initiative.
By lowering the sea urchin population and enabling the kelp to regenerate, this has helped to restore the ecosystem's equilibrium. In order to safeguard the species and assure its survival, the government has also imposed limitations on the hunting of sea otters.

Closed and Open Systems
An open system is one that receives input from
outside the system. For example, your body is an
open system because it receives food and oxygen
from outside the system (your body). What is another
example of an open system?
A rock in a field
An earthworm taking in soil for nutrition
Answer:
earthworm taking soil for nutrition
Explanation:
it's consuming the energy unlike the rock
An earthworm taking in soil for nutrition is another example of an open system, option B is correct.
An open system is characterized by its ability to exchange matter and energy with its external environment. In the case of an earthworm, it actively takes in soil for nutrition, breaking down organic matter and absorbing nutrients through its digestive system. This process allows the earthworm to grow, reproduce, and carry out essential life functions.
The exchange of soil, nutrients, and gases (such as oxygen) occurs continuously, sustaining the earthworm's biological activities. In contrast, a rock in a field does not interact with its environment in the same way. It remains a closed system, passively experiencing natural forces without actively receiving external inputs or engaging in metabolic processes, option B is correct.

A.passive transport
B.active transport
C. Mitosis
D. Replication
Answer:
A.
Explanation:
osmosis and diffusion are both passive transport bc it doesnt require energy and only moves down cocentration gradient, never against concertration gradient. Give me a brainliest if i helped! ♡
When certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.
When diffusion takes place between compartments separated by a membrane permeable to that solute, it is called simple diffusion.
Passive transport does not require any additional energy other than the movement of the molecules, moving these in favor of their concentration gradient.
In other words, simple diffusion does not require ATP expenditure, since it is a spontaneous phenomenon.
The molecules that are mobilized by simple diffusion through the membrane are the nonpolar and small, the fat-soluble and the small polar ones, but without a net electric charge, such as H2O.
In the particular case of H2O, passive transport is called osmosis, the passage of water through the membrane by osmosis always takes place spontaneously and very quickly.
H2O will diffuse from the compartment with the lowest concentration of solutes or hypotonic medium, to the compartment with the highest concentration of solutes or hypertonic medium, in such a way as to equalize the concentrations in both compartments.
Therefore, we can conclude that when certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.

How do the hypothesis of microspheres and the RNA World hypothesis build off of each other?
Answer:
Microspheres are formed of proteins. It has been found that when an amino acid is permitted to get desiccated, then this amino acid produces proteins that in turn give rise to microspheres.
On the basis of the RNA world hypothesis, the first genetic substance was considered to be an RNA, and then later the DNA turned out to be the genetic substance of higher species during the passage of evolution. It was also believed that microspheres comprised encoded information within it, and at the time of the splitting of microspheres, this encrypted information may have got transferred to the upcoming generation.
