why do we need new body cells
Answer:
When we are adults many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often.

Some desert plants respond to darkness by opening their flowers at night to lure in pollinators. In
this situation, a plant's response system is working in conjunction with the —
immune system.
vascular system.
reproductive system.
root system.
Answer:
B
Explanation:
In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.
What is a vascular system?The complex network of conducting tissues known as the plant vascular system connects all organs and carries water, nutrients, organic compounds, and different signaling molecules throughout the body of the plant. The primary transport systems of plants, xylem and phloem, make up vascular tissue. They often coexist in vascular bundles that cross the roots, stems, and leaves of all plant organs. Water and dissolved ions are moved upward through the plant through the xylem, starting at the roots.
Clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms are examples of vascular plants (flowering plants). The group is known by its scientific names, Tracheophyta, and Tracheobionta.

Healthy ecosystems depend on–
Healthy ecosystems depend on a variety of factors working together in balance.
Some key factors include:
1. Biodiversity: Healthy ecosystems have a rich variety of species, including plants, animals, and microorganisms.
2. Nutrient Cycling: Ecosystems rely on the cycling of nutrients, such as carbon, nitrogen, and phosphorus, to support the growth and survival of organisms.
3. Energy Flow: Ecosystems depend on the flow of energy from the sun. Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis.
4. Interactions and Relationships: Healthy ecosystems are characterized by complex interactions and relationships among organisms.

A protein channel in a hydrogen ion pump is shown below. What would happen if the concentration of H+ ions were higher inside the mitochondrion than outside the mitochondrion when the channel opened?
Answer:
The H+ ions moves outside.
Explanation:
The H+ ions moves outside the mitochondria of the cell if the concentration of H ions were higher inside the mitochondrion than outside environment of the mitochondrion in order to equalize the pH or H+ ions concentration of both inner side of mitochondria and outer side environment. This movement of H+ ions from a region of higher concentration to the region of lower through a semi-permeable membrane is known as osmosis which has a positive effect on the cell as well as organelles of the cell.

Answer:
focusing on a single task is the best strategy for change
Explanation:
The career of Jacques Cousteau illustrates that focusing on a single task in life is the best strategy for the change in the social life of an individual as well as in the society. If a person performs many activities at the same time so its focus and concentration divides over the activities which is not more advantageous as compared to that person who focus on the single task until it is completed so focus on the single task in life is necessary for producing big change in life and in the society.
