Answer:
Virus enters into the host cell through a process called endocytosis.
Explanation:
Endocytosis is a process in which molecule enters into the cell through cell membrane. Virus also enter into the host cell through this process. After entering, the virus starts replication and grow in numbers inside the host cell and take nutrients from it which is used in the process of reproduction. When virus population increases, it cause infection to the neighboring cells.
Answer:
Sarcomere
Explanation:
A sarcomere is the basic contractile unit of muscle fiber. Each sarcomere is composed of two main protein filaments—actin and myosin—which are the active structures responsible for muscular contraction.
An invasive species, such as the trees in your question, could:
- Out compete the native flora for resources, such as nutrients.
- An earlier reproductive and faster growing cycle could quickly surpass native tree growth.
- This alien species taking the place of native trees could disrupt the habitat of animal species that need the native flora instead.
The statement that is correct regarding the troposphere and the stratosphere is The ozone layer is in the stratosphere. The third one is true. The ozone layer acts as a protection layer that prevents UV light.
<h3>What are the layers of the atmosphere?</h3>
The atmosphere is divided into many layers, with the troposphere close to the earth and the thermosphere toward the sun, as shown in the diagram. in between two layers, such as the tropopause, which is present between the troposphere and the stratosphere. In the stratosphere, the ozone layer is present, which prevents the sun's UV rays from falling on the earth, and the troposphere is the region where the clouds are formed.
Hence, the correct answer is the third option, which is "The ozone layer is in the stratosphere."
