Answer:
13L:11D
Explanation:
Based on the photoperiod there are two types of plants -
a) Short day plant
b) Long day plant
Here the term short and long day do not mean that the provided length of day are the critical length of day required for reproduction. But opposite to that it means that the length of the day required for reproduction must be
a) Shorter than the defined length of day for short day plant
b) And longer than the defined length of day for long day plant
Chrysanthemums is a short day plant and thus option 1 with 13L:11D will produce fully developed flower buds
Option A is correct 13L:11D
1. respiratory system
sorry i’m not sure about the second one !
I think the correct answer from the choices listed above is the last option. Manure is carried by rain water from land to a river. This is an example of non-point source pollution. This type of pollution <span>is caused by rainfall or snowmelt moving over and through the ground. Hope this answers the question.</span>
Antoni van Leeuwenhoek and Robert Hooke first discovered the presence of the microorganisms in the environment during 1665-1683. Using the microscopes, the discovered that there are many tiny life forms that are not visible to the naked eye. This discovery led to the shattering of the belief that the life forms can appear out of the ruined non-livings forms, and gave rise to the cell theory.
The cell theory states that the cells are the basic unit of the life, and every living organism is composed of these cell(unicellular) or cells(multicellular). The new cells arise from the already existing cells.
Hence, the answer is cell theory.
Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
