Tortoises found on the Galapagos Islands can have varied phenotypes. One of the variations in the phenotypes is with regard to
their shells. They can have a domed shell with a hood above the head. The shells without domes lack the hood above the head,
such that the tortoise's neck is always pointing downward. A group of evolutionary biologists studied the tortoise population for
generations on these islands. The study coincided with a severe drought in the area that lasted many years. The data for the
changes in tortoise shell shape is shown here. Evaluate the data and select the statement that is best supported by this data.

Answer:

A

Explanation:

the process involves replication of cell's chromosomes, segregation of the copied DNA and splitting of parent cell's cytoplasm

In order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.

DNA replication is the process by which the genetic contents of a cell, the DNA, are copied which is a crucial process that occurs in all living organisms and is necessary for the maintenance of their genetic information and the transmission of this information to the next generation, it is essential for cell division and growth, as well as for the repair of damaged DNA and plays a central role in animals and plants, as new life can form and cell division takes place due to this process.

Hence, in order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.

Explanation:

Answer: 1. C) increased water temperature upstream. 2. D) introduce new predators to an environment. brainliest??

Explanation:

The change that is an environmental effect of building dams is increased water temperature upstream, which is in Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is in Option A.

Human activities are the primary cause of species endangerment and extinction, so humans must take actions to reduce environmental impacts in order to increase the rate of endangered or extinct species, and by reducing hunting and poaching and restoring degraded ecosystems can help protect endangered species, and reducing carbon emissions and promoting sustainable development can help mitigate the effects of climate change.

Hence, the effect of building dams is increased water temperature upstream, which is Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is Option A.

Answer:

A the movement or organisms or their genetic material from one population to another

Answer: number 1

Explanation:

In population genetics, gene flow is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population.

Explanation:

Answer:

Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

Answer:

The discovery that birds evolved from small carnivorous dinosaurs of the Late Jurassic was made possible by recently discovered fossils from China, South America, and other countries, as well as by looking at old museum specimens from new perspectives and with new methods. The hunt for the ancestors of living birds began with a specimen of Archaeopteryx, the first known bird, discovered in the early 1860s. Like birds, it had feathers along its arms and tail, but unlike living birds, it also had teeth and a long bony tail. Furthermore, many of the bones in Archaeopteryx's hands, shoulder girdles, pelvis, and feet were distinct, not fused and reduced as they are in living birds. Based on these characteristics, Archaeopteryx was recognized as an intermediate between birds and reptiles; but which reptiles

Explanation:

Natural selection will  only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.

Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.

Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.

Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,

These are the conditions that are said to be both necessary and sufficient for natural selection.

Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.

Thus, the correct option is d.

Answer:

The solubilities in water of the three molecules from most to least soluble is in the following order: phosphate > deoxyribose > guanine.

Explanation:

The phosphate group is the most water-soluble due to it being very much negatively charged .

The deoxyribose which has several hydroxyl groups, is the next most water-soluble molecule.

The guanine molecule is hydrophobic, therefore, it is the least soluble in water.

A DNA molecule is composed of the three molecules: deoxyribose sugar, a phosphate group and a nitrogenous base which could either be a purine or a pyrimidine.

The three dimensional structure of DNA is such that the the phosphate groups and deodyribose sugars form the backbone of the structure on the outside of the DNA double helix where they are exposed to the aqueous environment of the nucleus. On the other hand, the hydrophobic nitrogeneous bases are located in the interior of the double helix where they are excluded from excludedthe aqueous environment of the nuclues. This structural arrangement is in accordance with the solubility of the molecules where the water-soluble phosphates and sugars are exposed to water while the water-insoluble bases are away from water.
