Answer:
Charles Darwin
Explanation:
Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.
In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.
Answer:
The cells wouldn't be able to photosynthesize
Explanation:
Chloroplasts absorb light energy, enabling photosynthesis. if they are damaged then the plant can't get light energy.
None: Only those mutations that occur in the germ line and result in gametes will have a chance of being passed on to progeny. An alteration in DNA that occurs after conception.
Somatic mutations can occur in any of the body's cells except germ cells (sperm and egg) and are therefore not passed on to children. These alterations can (but not always) cause cancer or other diseases. Mutations in somatic cells are called somatic mutations. Because they do not occur in the cells that give rise to gametes, the mutation is not transmitted to the next generation sexually. Human somatic cells have 46 chromosomes: 22 pairs and 2 sex chromosomes that may or may not form a pair. This is the 2n or diploid condition. Human gametes have 23 chromosomes, each of 23 unique chromosomes, one of which is a sex chromosome. Somatic cells are the cells in the body other than sperm and eggs (called germ cells). In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one inherited from each parent. Mutations in a somatic cell occur in somatic cells and are transmitted by mitosis, resulting in cancer. However, mutations in a gamete are passed on by meiosis, resulting in mutated offspring. A genetic mutation occurs during DNA replication, and chromosomal mutations occur during meiosis.

Scientific study of life( its structure,processes,etc)
"Bedding is the separation of sediments into layers that differ from one another in texture, composition, color, or weathering characteristics".
Option (b);
<u>EXPLANATION: </u>
Sediments mean the matter that gets accumulated in one place. Sedimentary rocks are the results of the rock due to the accumulation of small particles that get weathered from rocks or erosion over time. They get accumulated either on the bottom of the sea level or earth's surface and thus the sediment rocks are formed.
These layers of sediments that are created based on difference in their shape, size, color and composition results it in bedding.The size of rocks in bedding ranges from several millimetres to centimetres and it sometimes results in a meter thick.
