Since we now that the change in the first positicion C for a Timine allowed the emergence of lineages A and D, we could say its inverse for the emergence of C and E, that is 1 - T -> C. I attempt that since A and D, are a sister clade with C and E, so we the only change there would be the first base. In the branching point behind A - D; C - E, we could propose a change that precede both clades, of course this is a guess and also it is arbitrary. We could say, 2 - T -> C, that is, in the second position, both couples A - D; C - E have a Citosyne.Therefore we would propose that the branch behind the bifurcation (BBB) following A-D; C-E has in its first two bases -CT-. From this point, we move to the branching point that precedes the clades E-H, and B-G. Let's propose that a change in the third base occurs, that goes from A to G. So we would have in BBB this sequence: -CTA- and in the point we are actually inferring CTG. Then, behind the clade F-H, let's propose a change in the fourth position, that goes from G - A. Following the above procedure, the change behind the B - G clade will be 4 - A to G. So for example in the clade A-D we will have this DNA sequence -TCA. In the clade C-E the DNA sequence will be -CCA-. In the clade F-H -CTGA- while in the clade B-H -CTGG-

Why are sago palms gymnosperm?
How do they achieve fertilization/pollination?
Are they gametophyte dominant, sporophyte dominant, 50/50, or sporophyte only?
Answers
Sago palms or Cycas revoluta is gymnosperms because they reproduces through an exposed ovule or seed.
In gymnosperm Pollen from male cones blows up into upper branches, where it fertilizes female cones. Cycas revoluta is a cycad, not an actual palm. Pollination in gymnosperms involves pollen transfer from the male cone to the female cone. during transfer, the pollen develops to form the pollen tube and the sperm for fertilizing the egg.
In gymnosperm ovaries are absent, double fertilization does not take place, As male and female gametophytes are present on cones rather than flowers, and wind is the main source pollination.

A parent cell from a human starts with 23 pairs of chromosomes; how many pairs of chromosomes will be in each new cell following cytokinesis?
Answers
Answer:
46 I belive! hope this helps
23 pairs of chromosomes, or 46 chromosomes will be present in the new cells formed after cytokinesis.
The DNA is duplicated during interphase. Consequently, one chromosome is present in two copies.
This indicates that the parent cell now contains 46 pairs of chromosomes.
However, the cell divides into two during cytokinesis, leaving each daughter cell with 46 chromosomes or 23 pairs of chromosomes.
What is Cytokinesis?A single eukaryotic split into two daughter cells during the cell division process known as cytokinesis. After the latter phases of mitosis and meiosis' nuclear division, the process of cytoplasmic division starts. As the daughter cells separate during cytokinesis, the spindle apparatus divides and carries duplicated chromatids into the cytoplasm. Thus, it guarantees that the chromosomal number and complement are preserved from one generation to the next and that, barring exceptional circumstances, the daughter cells will be functional duplicates of the parent cell. Each daughter cell starts the cell cycle's interphase after telophase and cytokinesis are finished.To learn more about Cytokinesis, refer to:

A football player kicks a ball with a mass of 0.42 kg. The average acceleration of the football was 14.8 m/s².
How much force did the kicker supply to the football?
Answers
The kicker supply to the football is 6.22 N.
Solution:
F = m*a - A
F = Force = ?
m = mass = 0.42 kg
a = acceleration = 14.8 m/[tex]s^{2}[/tex]
Plug the values in equation A:
F = 0.42 * 14.8
F = 6.216 N
F = 6.22N.
An NFL kicker's foot average force during a kick is about 450 pounds 2002 N and the ball can even deform on contact so kicking is a large power imbalance. A soccer ball is kicked with the power of the leg muscles. Therefore, the forces exerted are muscle forces. Strength is the force produced by using a body part such as an arm or leg. Since there is contact between surfaces, it is the contact force created by muscle activity.

The presence of a basidiomycete is one of the most important features of basidiomycetes. Basidium usually has four called basidiospores but can have two or eight. In typical basidia, each basidiospore is born at the tip of a thin prong or horn called a sterigma and is forced out upon maturity.
The basidium genius serves as the site of nuclear fusion and meiosis the function at which gametes fuse exchange nuclear material, and divide to reproduce basidiospores. The fungi of the phylum Basidiomycota are easily recognized under the light microscope by the swollen end cells of the hyphae, club-shaped fruiting bodies called singular.

Lizards with the longest legs are able to climb in order to reach high sources of food and escape the ground when floods or storms occur. Weather conditions for seven years are shown below.How might natural selection act on the lizard population if this pattern continues over time?
Answers
Solution:
Note that according to the table, the rainfall increased each year, which will endanger organisms that are above ground and cannot climb. Now, because the longer-legged lizards can climb to reach high food sources and escape from the ground when floods or storms occur, then these members of the population have better characteristics, depending on the environment they are adapted to (lots of rain ). Therefore, according to natural selection, these lizards will probably have a higher survival rate and therefore will be more likely to prevail and their genes to be inherited from generation to generation.
