Answer:
los aspectos más relevantes son aquellos destinados a fomentar acciones conjuntas con el objetivo de revertir problemas ambientales y plantear políticas públicas asociadas al desarrollo sostenible en ciertas regiones del planeta
Explanation:
El informe de Brundtland es un documento desarrollado en 1987 con el propósito de abordar el problema del desarrollo económico y social desde una perspectiva medioambiental, planteando así por primera vez el concepto de 'desarrollo sostenible'. El documento analiza con una mirada crítica las políticas de desarrollo económico que se llevan a cabo sin considerar la sustentabilidad medioambiental. El informe lleva el nombre Brundtland en honor a la primera ministra de Noruega durante parte de 1980, Gro Harlem Brundtland. El documento fue revelador para su época ya que visibilizó el problema del desarrollo económico y social en función de la sustentabilidad de nuestro planeta. Un punto importante a tener en cuenta del informe es que a fines de sustentabilidad medioambiental la población mundial no podría seguir creciendo a niveles exponenciales como los observados actualmente o a fines del siglo pasado, prediciendo que este valor se debería estabilizar en un valor entre los 7.700 millones y 14.200 millones de personas.
Answer:
The correct answer would be mitochondria or chloroplast.
Endosymbiosis refers to the evolution theory which explains the origin of eukaryotic cells from prokaryotic cells.
It is believed that cell organelles like chloroplast, mitochondria et cetera were free-living early prokaryotic cells which were taken inside the other cells by the process of endosymbiosis. It led to the origin of eukaryotic cells which were able to perform photosynthesis.
Thus, Keiko should mark chloroplast or mitochondria in the diagram.
Answer:
mitochondria, chloroplast
Explanation:
Answer:
The correct answer would be - Species removal experiment and the DeWitt Replacement experiment.
Explanation:
The competition can be increase for the various resources such as habitat, nutrients, water, and many more due to the territorial behavior of interspecific species.
The influence of the interspecific behavior such as competition influences on the population size of the species, two important tests are used are species removal experiment, and DeWitt Replacement exp commonly eriment.
Thus, the correct answer is - Species removal experiment and the DeWitt Replacement experiment.
Final answer:
When crossing a heterozygous round, tall F1 pea plant with a homozygous wrinkled, short pea plant, the probability of the offspring being wrinkled and tall is 1/4.
Explanation:
In pea plants, we have two traits where round seed shape (R) is dominant to wrinkled seed shape (r), and tall height (T) is dominant to short height (t). When a homozygous round, tall plant (RRTT) is crossed with a homozygous wrinkled, short plant (rrtt), the resulting F1 generation will all have the genotype RrTt (heterozygous for both traits). If these F1 plants are then crossed back to the wrinkled, short strain (rrtt), we need to look at each trait separately to determine the phenotype ratios.
For the seed shape, the F1 plants (Rr) crossed with the wrinkled, short (rr) can produce offspring with either Rr or rr genotype. Therefore, the probability of having a wrinkled (rr) offspring is 1/2. For height, the F1 plants (Tt) crossed with the wrinkled, short (tt) can also produce offspring with either Tt or tt genotype. The probability of having a tall (Tt) offspring is 1/2 as well. To find the proportion of offspring that are wrinkled and tall, we multiply the probabilities of the independent events: 1/2 (chance of being wrinkled) × 1/2 (chance of being tall) which equals 1/4.
Therefore, the proportion of offspring that will be wrinkled and tall from this cross is 1/4.
a. 8n
b. 1n
c. 4n
d. 2n
e. 0n
b.what is the ploidy level at prophase of mitosis
The answer is d. 2n
Drosophila melanogaster have four pairs of chromosomes, so the normal cell would have 4n(four pairs) of chromosome. metaphase is the phase of cell division where the chromosome start to lining up in the middle. In meiosis II, the chromosome is already divided into half, so the total chromosome of the cell would be 2n(half of the 4n)
2) Tetany
3) relaxation
4) repolarization
Answer:
Tetany
Explanation
The refractory period in the heart refers to the shortest interval between consecutive contraction conducted impulses out of the cardiac muscle.
It is important because it allows adjustments to stimuli and limits amount of action potential sent per minute.
Without a plateau extending the refractory period in the cardiac muscles.
Sarcomeres might be stimulated to contract instead of relaxing leading to sustained contraction also called Tetany.
Tetany is an involuntary muscle cramp or contraction caused by overly stimulated nerves.
