Answer:
1.5 billion years ago
Explanation:
Protists are a collection formed up of protozoa, unicellular algae, and fungus forms. We will focus on the being part of this society: the protozoa (proto = first, zoa = beings). Protozoa are the earliest discovered collection of heterotrophic living that utilize and modify complicated meal particles into power. Although protozoans are only made up of a single cell, these organisms control to perform all the necessary responsibilities of life. The protozoa are split into four principal associations: the ciliates, the flagellates, the heliozoans, and the amoebas.
Answer:
CGTCATC
Explanation:
In a DNA double helix, the complementary bases of two strands of DNA are paired by hydrogen bonds. Adenine of one DNA strand is paired with the thymine of the other strand. Similarly, the guanine of one DNA strand is paired with the cytosine of the other DNA strand. If a portion of one of the two strands of a DNA molecule has the sequence GCAGTAG. The sequence of the other strand would be as following:
One DNA strand: GCAGTAG
Other DNA strand: CGTCATC
The question is incomplete. The complete question is attached below.
Answer:
1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.
2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.
3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .
4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
Miss Philadelphia. The part of the root that contains transport tubes is the root hair. The primary role of the root hair is to absorb water and nutrients from the soil.
