The two sides of the DNA ladder are connected down the middle by many _______ bonds. *

Answer:

1. metaphase II - 7.3 pg.

2. prophase I - 14.6 pg.

3. G1 - 7.3 pg.

4. after cytokinesis of meiosis II - 3.7 pg.

5. telophase I before cytokinesis - 14.6 pg.

6. G2 - 14.6 pg.

Explanation:

The cell cycle begins at G1, where all cells in humans (except for the gametes) have 23 pairs of chromosomes, 46 in total, and without any part of the DNA being duplicated. This is the stage in which the cell will have 7.3 pg of DNA.

After G1 comes phase S, which is the phase in which the DNA is duplicated to prepare the cell for the oncoming division; so we can infer that the phase that comes after S, G2, will have twice the DNA the cell had initially: 14.6 pg.

With this amount of DNA, the cell enters the first part of meiosis, in which the homologous chromosomes will be separated into two cells that will each carry on with the second part of meiosis. In prophase I, the cell is just beginning the process of meiosis, so it has 14.6 pg of DNA. In telophase I, the cell still has that amount of DNA because cytokinesis hasn't happened yet, and that is the defining step that ends up actually dividing the cell into two.

Meiosis II begins after cytokinesis I, therefore, the homologous chromosomes have already been separated and each cell has now 7.3 pg. In metaphase II the cell has 7.3 pg, but when cytokinesis of meiosis II ends, the cell will be half the size that was just before, because the sister chromatids are separated - this is where the cell will only have 3.7 pg of DNA.

The cells produced by meiotic cells are gametes, having only 23 chromosomes and the lowest amount possible of DNA.

Answer: keeping a detailed record of the procedure and results of a scientific, conducting a experiment to confirm the effects of gravity on earth, solving a expression in steps using the order or operation

Explanation:

Descartes's rules for scientific reasoning include keeping a detailed record of all the procedures and results of a scientific experiment, conducting an experiment to confirm the effects of gravity on Earth, and Solving an expression in steps using the order of operations. Thus, the correct options are A, B, and E.

Descartes described the important rules which he established to make sure that the conclusions made in the experiment are true. These rules are as follows:

1. accepting nothing as true that is not self-evident, and perform experiment to prove anything

2. Divide the problems into their simplest parts, and keeping the detailed records of each and everything

3. Solve problems by proceeding in a stepwise order of operations in a scientific study.

Therefore, the correct options are A, B, and E.

The basic unit of life has to be a living thing, atoms aren't alive yet they make up cells, which are alive. However, atoms are building blocks of everything. Yet cells themselves are living, therefore are the building blocks of all forms of life.

Atoms are smaller than cells. Yet cells are the building blocks of life because atoms are not living, and living organisms are made up of cells because cells are living components.

Cells are the basic components of living organisms. Atoms are the basic and smallest unit of matter that is nonliving.

Since atoms do not have life, they cannot be the fundamental building block of life; nonetheless, they do makeup living cells.

Atoms are the fundamental units of matter, nevertheless. However, because cells are living entities in and of themselves, they serve as the foundation for all life.

Thus, cells are larger than atoms. However, as atoms are not alive, cells are the fundamental unit of life, and since cells are living entities, they are the foundation of all living things.

Kinetic energy depends on the potential energy of an object but they both have similar factors as they are inter-related. Kinetic energy is the motion of the object depending on its potential.

Potential energy is a positional based value, it literally means what it says, the potential or possibility for the creation of energy.

Answer:

Cones, Flowers, Fruit

Explanation:

The parts of plant are either said to be vegetative or reproductive. The vegetative part are those parts of a plant that have nothing to do with reproduction (sexual). The reproductive parts are those parts that have to do with the reproduction. According to this question, the CONES, FLOWERS, AND FRUITS are those parts that have a direct role in the reproduction of plants.

- Cones, also called strobili, are structures on which gymnosperms bear their seeds/reproductive structures. The cones can either be male or female.

- Flowers are reproductive structures unique to a group of plants called ANGIOSPERMS. The flowers can either be male called STAMEN or female called PISTIL.

- Fruits are the matured ovary of a flower, which bears in them, the seed of the plant. They are formed after fertilization has occurred in the ovary. Hence, they are involved in reproduction.

The list that accurately denotes parts of a flower that has a direct role in reproduction is ; ( B ) Cones, Flowers and Fruits

Cones are parts of a plant where gymnosperms bear its seeds, they are found in Non-flowering plants containing the reproductive organs of the plants.

Flowers are unique to flowering plants, they are contain the male and female reproductive gametes in plants ( pollen grains and ovules ).

Fruits contains the seed of plants and they are formed after the pollination of the ovules by the pollen grains contained in the pollen .

Hence we can conclude that the list that accurately denotes parts of a flower that has a direct role in reproduction are;  Cones, Flowers and Fruits.
