Answer:
D
Explanation:
Without a host a virus is without key nutrients to survive
prokaryotic cells
cell walls containing cellulose
sexual reproduction
The characteristic that does not apply to plants is prokaryotic cells.
The characteristic that does not apply to plants is prokaryotic cells. Plants have eukaryotic cells, which are more complex and contain a nucleus. Prokaryotic cells, on the other hand, are simpler and do not have a nucleus.
Plants are multicellular organisms with tissues, meaning they are made up of many cells that work together to perform various functions. They also have cell walls containing cellulose, which provide structural support.
Lastly, plants undergo sexual reproduction where male and female gametes combine to form offspring. This allows for genetic diversity and adaptation to different environments.

Heart attacks reduce blood flow to the heart and cause coronary artery disease.
Coronary artery disease can reduce blood flow to the heart and cause heart attacks.
Heart attacks occur when coronary artery disease is treated.
coronary heart diseases occur when the arteries are blocked with fatty deposits
so there is less blood flow to the heart. less oxygen and nutrients to the heart. this leads to heart attack. coronary diseases lead to attacks
Answer: True
Succession is the phenomena in which changes in the biotic and abiotic factors of the environment leads to change in the ecosystem. A succession is a process in which a biological community is replaced by another biological community until a mature ecosystem is formed this process is influence by environmental factors. Primary succession is the primitive environment where no biotic community previously existed it is followed by secondary and subsequent succession were life forms develop and form an ecosystem. Some of the environmental factors are:
Topographical : These are the change in the region or habitat were succession occurs. Landslides, volcanic eruption, glacier melting etc. are the examples , as these topographical changes can bring reformation of the landscape. The disturbance caused by these topographical changes will allow the disturbance tolerant species to repopulate the habitat. This can be a transition from primary to secondary succession.
Soil : It is an abiotic factor.The growth of the plants requires suitable soil conditions. The type of soil will affect which species will inhabit the area. The soil moisture and pH greatly affect the number of plant species in an area.
Climate : It can influence the direction of succession. Climatic factors includes rain, wind etc. For example a region lacking proper rainfall the species will be tolerant to dry and drought conditions. The region with heavy rainfall, the species will be more tolerant to moisture. Wind being a climatic factor can cause wind erosion affect the soil quality. Wind can lead to heavy forest fires can therefore, wiped out community.
Succession takes place when environmental factors affecting an ecosystem change. Therefore, the given statement is true.
Succession refers to the process of ecological change over time in a particular area or habitat. It involves the progressive and predictable sequence of changes in species composition and community structure, leading to the development of a stable and mature ecosystem.
It can occur in both terrestrial and aquatic ecosystems. It is typically categorized into two main types: primary succession and secondary succession. It is a dynamic process.
