D. If you have scratch paper and draw it out, it would greatly help you. A different way would be to visualize it in your head. Behind the Earth is Full moon, in front is new moon, above/below is half/gibbous. To the right of below is 3/4. To the left of below is 1/4. To the right of above is also 3/4. To the left of above is 1/4.
That's at least one of his parents are heterozygous
A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.The two strands run in opposite directions, one going in a 3' to 5' direction and the other going in a 5' to 3' direction. The nitrogenous bases are positioned inside the helix structure like "rungs on a ladder," due to the hydrophobic effect, and stabilized by hydrogen bonding.
Uracil is one of the four nucleobases in the nucleic acid of RNA that are represented by the letters A, G, C and U. The others are adenine, cytosine, and guanine. In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleobase is replaced by thymine. Uracil is a demethylated form of thymine.
hope this helps
Answer:
the top 2 from left to right are: petal and stigma(*).
The one that follows from top to bottom is anther(#) and the one below is the filament.(#)
to the right there is the style(*) and below there is the ovary(*)
to the left of that, the last one with no symbol is the sepal
the last 2 sentences in the bottom are pistil and stamen
Answer:
A)All organisms are composed of one or more cells.
B)All cells have membrane-bound structures that have certain functions.
D)The cell is the basic unit of organization on organisms.
Explanation:
Created by Mathias Scheiden and Theodor Schwann, Cell Theory involves the assertion that all living beings are formed by cells and that these cells have functional structures, which was possible as a result of the development of microscopy, being, today, a of the most important generalizations in the field of Biology.
In addition, according to cell theory, the cell is the smallest unit of life, and new cells are formed from the division of cells that already exist, and this process occurs from cell division. Another important pillar of this theory is the fact that the cell is the unit of reproduction and transmission of inherited characteristics, that is, all genetic characters transmitted from parents to children, are transmitted from one cell to another in the process of reproduction.
In summary, cell theory states that:
- All organisms are composed of one or more cells.
- All cells have membrane-bound structures that have certain functions.
- The cell is the basic unit of organization on organisms.
