D.The purple-spotted butterflies in your collection have more spots than the purple-spotted butterflies your grandfather collected when he was a child.
E.A giraffe's neck is longer than a deer's neck

Answers

Answer 1

Answer: The examples of species changing over time are statements A, C, and D.

All these changes, such as new types of squash was developed in the garden. weeds evolution to resist chemicals, and the changes in butterflies wing pattern over the years is because of Mutation. Obviously, rabbit's ears are always bigger than mice and Giraffe's neck is always longer than the deer's. In genetics, mutation is the process of permanent alternation of the nucleotide sequence in DNAs.

Why didnt the present shapes of the continents fit perfectly into a supercontinent

Answers

The borders (coastlines) of the continents underwent a number of changes since the split. Often, chunks of land were washed away with water, slowly or in bigger portions. The coast was generally "smoothed" by the ocean currents too, and in some places more land was added with the material that the ocean currents brought.

Then, the tectonic plates continue to move, so this adds to the changes of the shape of the continents.

Answer:

because of erosion and the shifting of tectonics places ver slowly and continuolsy changes the shape of the land

In meiosis II what happens during anaphase?

Answers

Answer:

Pulling apart or separation of sister chromatids

Explanation:

Meiosis is a type of cell division that results in four daughter cells with each having half number of chromosomes as the parent cell. It is the cell division that leads to formation of gametes to enable sexual reproduction. Division occurs twice during meiosis because before the two halves of a duplicated chromosome called sister chromatids separate, it still needs to separate homologous chromosome, which is a similar but non-identical pair of chromosome received from both parents. Hence, meiosis occurs in a two step division process i.e. Meiosis I and Meiosis II.

Meiosis II is the mitotic division of each of the haploid cells produced in meiosis I. Note that, homologous chromosomes separate in anaphase I of meiosis I, and further undergoes cytokinesis (division of cytoplasm) to produce two haploid (reduced number of chromosomes) daughter cells.

During anaphase of meiosis II, the individual chromosomes (sister chromatids) separate at the centromeres (point of attachment between two sister chromatids). The separated chromosomes are pulled apart towards each pole of the cell by the spindle fibres.

Meiosis II the chromosomes are pulled to the center of the cell and line up randomly at the equato
Anaphase II the centromere of each chromosome splits -the sister chromatids separate and move to opposite poles

Which of these statements about animal cells and plant cells is true.?

Answers

A cell is the most basic form oflife. It is what most of the organisms are made off. For the organism tofunction, the cell must also function. It has organelles too that helpsfunctions what the microorganisms need. A leaf cell contains chloroplasts thatanimal cells and animal cells do not have. The chloroplast is where the photosynthesis happens. It needs sunlightfor the process of photosynthesis. Notice that the leaf has a broader surfacearea to enable them to be exposed to the sun.
