Tundra biome has a very harsh winter and a cool summer. It has a very low level of precipitation. Because the ground is permanently frozen, only algae, mosses, and lichens are found as vegetation. Animals that live in this biome must be well equipped to combat the very cold weather like the polar bear, artic fox, and snow owl.
Answer:
C) eukaryote A) bryophyte D) moss B) seedless plant
Explanation:
According to Whittaker five kingdom classification, the most specific classification includes prokaryotes and eukaryotes . Unicellular organisms were placed under Monera whereas Multicellular organisms were placed under Eukaryotes. Based on the cell wall, Eukaryotes were further divided into plantae and animalia. Plantae includes Thallophytes, Bryophytes (lacks differentiation of stem, leaf and root), Pteridophytes (seedless vascular plants), Gymnosperms (naked seeds) and angiosperms (Flowering and non- flowering plants).
Answer:
The genotypes thatwould be considered pure breeds are BB and bb
Explanation:
The genotype of an organism refers to an organism's complete set of genetic material or genes.
Genes are units of DNA that carries information for a particular physical or functional trait or character in an organism. Some genes act as instructions to make proteins while some genes do not code for proteins. The proteins made by a gene expresses the traits and characters of that organisms. Genes for a particular trait may have one or more variants known as alleles.
In Gregor Mendel's research using pea plants, flower colour in a pea plant had two different alleles; one for red flower colour and one for white flower colour. If a plant had the same allele for flower colour, the plant was considered a pure breed.
For example, given B was the allele for red flower colour and b was the allele for white flower colour, a plant having the two alleles for white flower colour bb, is a pure breed. Similarly, a plant having the two alleles for red flower colour, BB is a true breed.
Immature seed cones of conifers are usually green before pollination, and flowers of grasses are inconspicuously colored. What does this indicate about their pollination? they are wind pollinated.
