Answer:
Species compete for water when this resource is limited, this limit occurs when there is a shortage of rain, or very high solar radiation. Under these conditions the bodies of water are dried
An example of this competition is when there are 3 species of plants that with their roots suck the water from the ground freatic level, those that have longer and more effective roots can survive.
different alleles.
B. Plants can grow to a wide range of
heights.
C. Humans either have attached
earlobes or detached earlobes.
D. Human body mass is controlled by
many genes.
The Mendelian trait are those controlled at only single gene locus. The Mendelian trait have two alleles (one form each parent), out of which one allele is dominant while the other is recessive. The dominant allele will express in both homozygous and heterozygous conditions while the recessive allele will express itself only in homozygous condition. An example of the human Mendelian trait is the attached or detached earlobes. A human will either have attached earlobe or detached earlobe.
Hence, the correct answer is 'Option C - humans either have attached earlobes or detached earlobes'.
c. Most species are motile.
b. They are plant-like organisms.
d. They have membrane-enclosed nuclei.
Protists belong to the group eukaryotes (having their DNA enclosed inside the nucleus). They are not plants, animals or fungi but they act like one. They can be in general subgroups such as unicellular algae, protozoa and molds. They thrive in environments with little sunlight. But they are not plant-like organisms. The answer is letter B.
We design a model that explains how your experiment demonstrated the transfer of genetic material from father to offspring. In our model, we clearly identify where the transfer of genes from parents to children took place, and in this practical way, we explain heredity.
Heredity is the biological system of transmission of certain characteristics of living beings between generations. For the full functioning of this structure, genes are needed – a piece of DNA (deoxyribonucleic acid) that houses genetic information.
Some properties can remain inactive for generations, which does not represent their extinction, only the forgetting of one or several genes. However, this does not make it impossible for the carrier of the dormant gene to pass it on to their descendants.
In addition, genetic information is capable of disappearing as a result of environmental and climate change. In these cases, natural selection processes directly affect heredity.
With this drawing, it was possible to visualize how gene transfer occurs in a normal situation.

Behavioral cycles that repeat daily are called circadian rhythms.
Circadian rhythms are behavioral, physical and mental changes that occur in living organisms (plants, animals, fungi and cyanobacteria) and follow a 24hours (daily) cycle. Circadian rhythms regulate many physiological processes and they are influenced by external cues such as sunlight and temperature. They determine when to sleep, when to eat or whether an individual feels wide-awake, or feels tired at different times of the day.
