How are thorns and spines related to drought resistance?
Answer:
To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns or spines.

The type of evidence is indicating that eukaryotes are more closely related to archaea than bacteria is BIOINFORMATICS. This field of study compares nucleotides (DNA) sequences.
Bioinformatics is an interdisciplinary discipline that uses computational tools to interpret biological data.
This field of study (bioinformatics) compares nucleotides (DNA) sequences in order to determine the evolutionary level of shared ancestry between species.
For this purpose, bioinformatics uses the linear order of nucleotides in order to compare different species.

An organism that produces offspring identical to the parent when self-fertilized is known as a true-breeding organism. It is also called purebred.
A true-breeding or purebred is a type of organism that always passes specific phenotypic traits to its offspring.
A true-breeding must be homo-zygous (i.e., purebred) to pass certain phenotypic features to offspring.
True breeding organisms are very useful in conventional breeding techniques to pass desirable phenotypic traits to offspring.

Hey mate....
Explanation:
This is ur answer...
Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up. The thick brown or black substance that remains after most of the organic litter has decomposed is called humus.

Which of the following statements about the law of independent assortment is correct?
A. It is the reason that dominant alleles are visible in the organism's phenotype.
B. It is the consequence of having two copies of each chromosome in somatic cells and one copy in gametes.
C. It describes the inheritance of different genes relative to one another.
D. It describes the inheritance of different alleles relative to one another.
The statement about the law of independent assortment which is correct is: C. It describes the inheritance of different genes relative to one another.
Independent assortment can be defined as a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
This ultimately implies that, the inheritance pattern of different genes with respect to another gene is given by the law of independent assortment.
In conclusion, the law of independent assortment describes how different genes separate with respect to another gene during the development of reproductive cells.

According to the text, the main reason that humans are one of the few species to have long, committed relationships is that:
humans think that they need to connect more than animals for animals it's all about survival making love hard. Animals only think about mating and staying alive. but humans have the time to think about love.
The main reason that human beings are one of the few species to have long, committed relationships is that: human babies are born before they are completely advanced and for that reason need a number of care.
What defines a species?Species are characterized by means of the reality that they're reproductively remoted from different organizations, which means that the organisms in a single species are incapable of reproducing with organisms in any other species. The term species also can be described as the maximum fundamental category within the device of taxonomy.
