Protonema have large surface area to volume ratio you can predict that
Vaselesa [24]

Answer;

-They are absorptive interfaces with the environment.

Explanation;

-The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

-The surface area to volume ratio of an object is the relationship between two measurements. It is the ratio of Surface area to volume. It shows the comparison between the size of the outside of an object and the amount inside. Small or thin objects have a large surface area compared to the volume.

Which of the following describes a properly controlled experiment?
netineya [11]

Answer:

Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.

In a controlled experiment, impact of one independent variable is studied on the dependent variable.  

Here in this study sunlight is the independent variable while the radish plant is dependent variable.  

The researcher wants to study the effect of sunlight on radish plants when they are exposed to it   and compare it to the effect created on radish plants  that are kept in dark.  

Hence option D is correct.

According to the ____________ theory of biological aging, dna in body cells is gradually damaged through spontaneous or external
aliina [53]

The Cross-Linkage Theory or also referred to as the glycosylation theory of aging was discovered or proposed by Johan Bjorksten in the 1940s. According to this theory, the aggregation of cross-linked proteins can damage cells and tissues this slowing down the bodily processes that eventually results to aging. In recent studies, cross-linking is associated with age-related changes in the studied proteins. Furthermore, this theory stresses out that the binding of glucose to proteins can cause various problems. Once the said binding occurs, the protein becomes impaired which leads to its performance inefficiency. Living a longer life would also mean increasing the possibility of oxygen-glucose meeting and protein. Some of the known cross-linking disorders include senile cataract and the appearance of tough, leathery, yellow skin.
