Researchers Robert Briggs and Thomas King used ultraviolet radiation to destroy the nuclear DNA of frog eggs. Nuclei from adult skin cells and from tadpole-gut epithelial cells were cultured and then injected into eggs that had their nuclei destroyed. The results were tadpoles. Which conclusion is supported by the data from this investigation?
Answers
Answer:
Nuclei of gametes and somatic cells are similar to each other in its function.
Explanation:
The conclusion of the data is that the nuclei of gametes and somatic cells are similar to each other because both performs same function in the cell i.e. regulates activities of the cell. The nuclei of somatic or skin cells work efficiently in the egg cells due to similar composition and structure of nuclei that performs similar function in the cell so that's why injection of skin cell's nuclei into egg cells results the same i.e. formation of tadpoles.

Which new animal adaptation may be favored if average
temperatures in a temperate forest decreases by 25
degrees C over 1500 years?
Answers
Answer:
If the average temperatures of temperate forests fell by about 25ºC during the period of 1500 years, the natural modification of the animals that would be favored would be that which allows an adaptation to the new climatic circumstances by the fauna of said forests, that is , to the notable drop in temperature. Thus, for example, animals would develop more voluminous furs, which would allow them to heat their bodies in a better way.

Answers
Answer:
Los alimentos son nuestro combustible y sus nutrientes proporcionan a las células del cuerpo la energía y las sustancias que necesitan para funcionar. Pero, antes de que los alimentos puedan hacer eso, los debemos digerir, descomponiéndolos en trozos pequeños para que nuestros cuerpos los puedan absorber y aprovechar.
El primer paso del proceso digestivo tiene lugar antes de que ni tan siquiera probemos la comida. Con solo oler una tarta de manzana casera o pensar en lo delicioso que va a saber un tomate maduro, empezamos a salivar, y el proceso digestivo se inicia preparándonos para ese primer bocado.
Casi todos los animales tienen un sistema digestivo en forma de tubo, donde los alimentos:
entran por la boca
pasan por un largo tubo
salen del cuerpo en forma de heces (caca) a través del ano
A lo largo del camino, se descomponen en moléculas diminutas para que el cuerpo pueda absorber los nutrientes que necesita:
Las proteínas se deben descomponer en aminoácidos.
Los almidones se descomponen en azúcares simples.
Las grasas se descomponen en ácidos grasos y glicerol.
Los residuos que el cuerpo no puede aprovechar son los que salen del cuerpo en forma de heces.

Answers
Answer:
The correct answer is - A. 25%.
Explanation:
In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.
Cross: AB blood type father with an A blood type mother (genotype AO)
Gametes: A, B and A, O

A AA AB
O AO BO
Here, there are 25% chances of AB blood group offspring 50% for the A blood group (AA and AO) and 25% B blood group (BO).

The difference in the climate is because of the latitude.
Explanation:
The climate of a particular region differs from that of another region because of many reasons. One of the reasons is the difference in the latitude of the regions. The difference is in the amount of solar radiation received by the different regions. In the polar region, the temperature is low and it is cold there. While, in the tropical regions, the temperature is high and therefore it is warm in these regions.

the diagram illustrates the three stages of cellular respiration. In which stage is carbon dioxide released?
Answers
Answer:
Kreb's cycle
Explanation:
As depicted in the image of this question, aerobic cellular respiration is made up of three stages namely; glycolysis, Krebs cycle and electron transport chain (ETC). Glycolysis is the first to occur in the cytoplasm of the cell, after which it is followed by Krebs cycle, which uses the products of glycolysis as a starting material.
At the end of Krebs cycle, 2 molecules of carbon dioxide (CO2) are released as waste products. This release of CO2 occurs specifically at stage 3 and 4 of the citric acid cycle or Krebs cycle.

Which of the following is the independent variable for a controlled experiment
investigating how waste production affects a certain person's ecological
footprint?
A. Opinion the person has about environmental impact
B. Measurement of the amount of waste produced
C. Identification of the person
D. Calculation of resulting ecological footprint
Answers
Answer: Measurement of the amount of waste produced.
Explanation:
Measurement of the amount of waste produced is the independent variable for a controlled experiment in this case. Therefore, the correct statement is option B.
What is the independent variable?The independent variable is the variable that can be changed in a controlled experiment. In this case, the researcher can manipulate the amount of waste produced followed by observation of its effect on the ecological footprint.
The researcher can manipulate the amount of waste by changing the factors such as the type of waste produced, recycling facilities available, etc. under controlled conditions.
Once the independent variable is manipulated, the researcher can observe its effect on the dependent variable. In this case, the ecological footprint of the individual is a dependent variable. The dependent variable is the variable that can be affected by the independent variable and is measurable.
Therefore, the measurement of the amount of waste produced is the independent variable for a controlled experiment.

Answer:
C. a distant luminous object travels rapidly away from an observer.
Explanation:
Option C is the correct answer.
Redshift is actually observed when a distant luminous object travels rapidly away from an observer.
In redshift, observers actually see an object that is travelling away from them and it has longer wavelength. The opposite is the blueshift where observers see a light traveling towards them and shifted to shorter wavelength.
In astronomy, redshift takes place when the object's visible light travels towards the red end of the spectrum.
A red shift is observed when a luminous object is moving rapidly away from the observer.
A red shift refers to a shift to a longer wavelength. It is observed when a luminous object is moving away from an observer. This is different from a blue shift where the luminous object is moving towards the observer.
Hence, in astronomy, a red shift is observed when a luminous object is moving rapidly away from the observer.

Answer:
Biodiversity is defined as the variety of life forms existing on the planet and the number of species living within an area. The notion also covers the way diversity changes over time and moves from one location to another (“Facts on biodiversity,” n.d.). There is terrestrial and marine biodiversity that includes species living on Earth and in the sea. A number of species dwelling in a particular area helps to monitor the aspects of biodiversity. Maintaining biodiversity is important for people’s well-being since it plays a significant role in the contribution to human health and provision of raw materials. However, currently people often face the loss of biodiversity. Today this process is happening at a much faster pace than it did 50 years ago (“Facts on biodiversity,” n.d.). As a matter of fact, around 90 percent of all the fish on the planet was exploited within the last 50 years, a quarter of bird kinds were killed, and 70 percent of forests was destroyed. In addition, extinction threatens 18 percent of all mammals, 5 percent of the fish, and 8 percent of plants. Thus, it is possible to assume that the loss of biodiversity on Earth, which takes place nowadays, is directly linked to anthropological factors, including overhunting, overfishing, consumerism, and agricultural practices.
