<span>Rocks can best be identified by their mineral content. This is
because rocks are composed of one or multiple numbers of minerals. Quartz,
calcite, feldspars, and micas are examples of minerals that make rock formations
possible.
Rocks are the basic component of the Earth's crust. Mountains, hills, and
volcanoes are examples of rock formations that occur through time on Earth. One
can find rocks all over the Earth and most are usually under the soil. Rocks
can be further classified as igneous, sedimentary, or metamorphic rocks.</span>
Answer:
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
Explanation:
Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.
<span>This is true. Surveillance can be performed efficiently through both stationary and mobile means. As far as human surveillance goes, people can track other people by tailing them or by using a stationary means such as a stake out. As far as technology goes, there are plenty of mobile devices that can be used for surveillance such as tracking devices. Security cameras can be used for stationary purposes.</span>
Answer:
C. their gametes do not require water for fertilization to occur.
Explanation:
Seed bearing plants are plants that produce seeds. The gametes of seed-bearing plants do no depend on water for fertilization. Fertilization could occur through the transfer of pollen from the male gametophtye to the female gametophyte through animals or wind.
Unlike other plant types like the bryophytes, they rely on water for fertilization. They so have xylem and phloem as well as other plants. They also have stems,roots and leaves like other plants.
Answer: 1) The phenotype of Rr is Pink according to incomplete dominance.
Incomple dominance occurs when none of the alleles is completely dominant over the other, resulting in blending of the phenotype from the parents. When a red (RR) and a white flower (rr) are crossbred, they result in Rr that is a pink phenotype.
2) According to Codominance, the phenotype of Rr is Red and White flower.
Codominance occurs when both the alleles are equally expressed. In this case allele for Red (R) and white (r) phenotype are expressed equally giving Red and White flower.
3) In Codominance, both the alleles are visible in the hybrid and in Incomplete dominance, intermediate (blend of parental) phenotype is visible in the hybrid.
