Which two conclusions can be made about the animals from their embryo structure?

1 answer:

5 0

The astonishing similarity in the appearance of embryos from different animal species was observed as far back as the 19th century by scientists such as Karl von Baer, Charles Darwin and Ernst Haeckel. Such observations prompted the hypothesis that the individual development of an organism reflects its evolutionary history or phylogeny. Two groups of scientists, including researchers at the Max Planck Institute of Molecular Genetics in Dresden and the Max Planck Institute for Evolutionary Biology in Plön, have now succeeded in demonstrating, for the first time, that parallels exist between individual development and phylogeny on the level of gene expression.

During cellular respiration, electrons are produced. The oxygen molecule accepts these electrons, then combines them with protons to make water. This outputs ATP, which is what the rabbit uses for energy. At the end of the process, carbon dioxide is released. From here, the carbon dioxide travels to one of the rabbit's favorite plants. This helps plants breathe. Sunlight penetrates the leaves of the plant, which are generating into sugar molecules within the chloroplast. The substance is known as chlorophyll. Electrons make the chemical process go more quickly. At the end, the plant releases oxygen back to the rabbit.

How can an excess of nutrients harm organisms in an ecosystem?

Neporo4naja [7]

Answer:

Excessive amounts of nutrients can lead to more serious problems such as low levels of oxygen dissolved in the water. Severe algal growth blocks light that is needed for plants, such as seagrasses, to grow. When the algae and seagrass die, they decay

You have isolated a new mutation in the T4 bacteriophage rII A gene and you map its location within the gene by recombination fr

pantera1 [17]

Answer:

A lethal mutation, thereby the resulting phenotype is not observed .

Explanation:

Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).
