Novosadov [1.4K]

Answer:

Each biome has a unique set of environmental conditions and plants and animals that have adapted to those conditions. The major land biomes have names like tropical rainforest, grasslands, desert, temperate deciduous forest, taiga (also called coniferous or boreal forest), and tundra.

Explanation:

A biome is different from an ecosystem. An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many ecosystems. For example, an aquatic biome can contain ecosystems such as coral reefs and kelp forests.

Snakes excrete waste products produced from the breakdown of food for energy.
Bingel [31]

The characteristic of life it represents is homeostasis.

<h3>What is homeostasis?</h3>

Homeostasis is the body's attempt to maintain a constant internal environment.

One of the major ways the body achieves homeostasis is through excretion, the process of removing wastes and excess water from the body.

Thus, when the snakes excrete waste products produced from the breakdown of food for energy, the characteristic of life it represents is homeostasis.

In an asexual species, a beneficial allele and a deleterious allele are in linkage disequilibrium. The selection pressure for th
Stella [2.4K]

Answer:

selective interference

 

Explanation:

Natural selection acts on genes that are inherited together, which is the case for species of asexual reproduction (where genes are inherited together by clonal offspring).  In asexual species, linkage disequilibrium (i.e., non-random association of the alleles of different <em>loci</em>), can be understood in a similar mode in terms of population allele frequencies. Selective interference underlies the association between beneficial mutations and surrounding sites which are subject to deleterious mutations. It has been shown that asexual species adapt at a slower rate than species of sexual reproduction. In sexual species, selective interference could be bypassed through the mechanism of recombination during meiosis (although there is not conclusive evidence of this). In asexual species, different deleterious and beneficial mutations are generally fixed, whereas beneficial mutations are generally spread and fixed in species of sexual reproduction.
