indicate the hypothetical evolutionary relationship between two species of their DNA sequences share a 98 percent similarity

1 answer:

6 0

This means that we are virtually certain to share a common ancestor at some point in our evolutionary history. Although this 2 percent difference can manifest itself as huge phenotypical differences between species (such as between humans and chimpanzees), it indicates that our species diverged relatively recently on the evolutionary timeline.

Which of these best explains why Earth’s inner core is solid?

Radda [10]

the temperature at which a phase change takes place depends on pressure. For instance because there is more pressure at low altitudes than at high altitudes, water boils at less than 100 degrees Celsius at high altitudes like mount Everest. In general, the higher the pressure, the higher the melting and boiling points are. Therefore potentially the melting point of iron-nickel alloys is significantly greater in the Earth's core than on the Earth's surface due to an enormous pressure within the Eaerth's core.

Which statement describes what happens during the germination of a pollen grain

Crazy boy [7]

During germination of pollen grains, the pollen grains produce a tube that grows down towards the ovary.

Germination we can term it as the process by which an organism grows from a seed or a similar structure pollen grains are reproductive structures which are also known as pollen tubes that produce male gametophytes. The first step is germination is an emergence of radicle which helps in supply of water to the growing embryo. During germination of pollen grains, it produces a tube that grows down towards the ovary. The growth of a plant which founds with a seed is called germination and it results in the formation of the grain. The companionship of male and female reproductive cells is where the seed of the vascular plant produces. Developed seeds contain an embryo and, where plant species store of food reserves, and wrapped in a seed coat. Different numbers of seeds lack nuclei which are produced by some plants, and they are called dry seeds and they never germinate. Ripe seeds that do not grow are called dormant seeds, and they are subject to external environmental conditions of metabolic processes and cell growth are prevented. Embryonic tissues resume growth, and seed begins to germinate developing towards seedling when given proper conditions.

What type of ion forms when an atom loses electrons

Shkiper50 [21]

The ion becomes an isotope when either it has lost an electron or gained one. The type of ion (the name) would be called "cation". This is because when an electron loses an electron, it becomes positive.
