In at least one paragraph explain your own stance in the debate between nature and nurture. Describe this debate and use evidence from the class or your
life to support your own beliefs about it. Your paragraph must be a minimum of five complete sentences with correct grammar, spelling, and punctuation

Answers

Answer:

There are specific things that us humans experience that are caused by nature and by nurture, but there are also things that they work together on as well. I believe that gender and gender expression is fueled by both nature and nurture. An experiment was conducted in England with toddlers and adults. The adults were to watch over the toddlers and play with them. What the adults didn't know is the toddlers were dressed as the opposite sex. A little girl dressed as a male was handed "boys toys" and a boy dressed as a female was handed "girls toys". But the scientist went even further with her research and went to a zoo. Chimpanzees are our closest relatives and were the target group for the experiment. Different gendered toys were placed about and one by one monkeys began to play with the twos. However, the male chimps played with the "boys toys" and the female with the "girls toys". So it was proven quickly that while it may seem like more nurture than nature, nature does play a role in gender expression.

Explanation:

Los procesos de respiración aerobia celular y fotosíntesis, procesos considerados indispensables para la vida en la tierra, de los que es correcto afirmar que Son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas. La respiración celular sólo la realizan los seres eucariotas del reino de los vegetales. Ambos son realizados por los seres considerados eucariotas. Ambos son realizados por eucariotas pertenecientes al reino de los vegetales

Answers

Respuesta:

Las opciones correctas son: a) son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas; y d) ambos son realizados por eucariotas pertenecientes al reino de los vegetales.

Explicación:

La fotosíntesis y la respiración celular son procesos de carácter antagónico porque la fotosíntesis es anabólica y la respiración celular es catabólica. La fotosíntesis consiste en la producción de moléculas complejas a partir de moléculas simples (proceso anabólico), mientras que en la respiración celular se degradan moléculas complejas y se las convierte en moléculas más simples (proceso catabólico).

Ambos procesos son realizados por los eucariotas del reino de los vegetales, pero los eucariotas del reino animal sólo realizan respiración celular, ya que no tienen cloroplastos. Esta diferencia tan importante existe porque los animales pueden moverse para conseguir comida (heterótrofos), mientras que los vegetales necesitan producir sus propios nutrientes haciendo uso de la fotosíntesis (autótrofos). Más allá de esta diversidad, todos los eucariotas realizan respiración celular para producir energía en forma de ATP.

Answers

The complete question is as follows:

Which characteristics of bacteria help them infect other organisms? Check all of the boxes that apply. Bacteria reproduce quickly. Bacteria have a protective layer called a capsule. Bacteria can evolve quickly because they can pass on genetic information. Bacterial infections cause symptoms that transfer the bacteria to new hosts.

Answer:

The correct answer is - all options are correct.

Explanation:

Bacteria can infect other organisms due to their different type of characteristics. These microorganisms infect the host cell by attacking them and increase their number rapidally. Host cell tries to kill these bacteria but these bacteria cells have a tough protective layer around their body prevent from any chemical or immune response.

Bacteria cells have a great feature to evolve fast in few generations which helps them developing resistance according to the condition for their survival.

Gains energy by eating other living thing

The characteristic that is shared by both primary and secondary consumers is that they gain energy by eating other living things. Therefore, option D is correct.

What are consumers in an ecosystem?

The primary consumers are the organisms that devour the producers. They are numerous and often modest in size. Herbivorous animals are the primary consumers (vegetarians). The organisms known as secondary consumers are carnivores that consume the primary consumers. Secondary consumers are consumed by tertiary consumers.

Herbivores, carnivores, omnivores, and decomposers are the four different categories of consumers in ecology.

Which of the following is true about molecules?
1. Composed of the two same atoms

2. Composed of two different atoms

3. H2O is an example of molecule

4. All of the above is true.

Answers

Answer:

4) All of the above is true.

Why?

When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. This is because they are all made up of different types of molecules. Molecules are not only made up of different types of atoms but also different ratios. Like in the water example above, a water molecule has 2 hydrogen atoms and 1 oxygen atom. This is written as H2O.

Answers

Answer:

c

Explanation:

got it right on edgenu1ty

The student hypothesizes that the green pod color in pea plants is dominant and the yellow pod color is recessive. An observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.

What is the importance of dominance?

The complete dominant allele will express itself in the heterozygous condition because it will suppress the recessive allele and express itself. Here, the green is dominant over the yellow, so the green can be purebred or can have a heterozygous condition, so the green pod having a heterozygous condition can produce both the green and the yellow pods. The yellow pods are recessive, so they can only produce yellow offspring, not green offspring, as they are only expressed in the purebred recessive forms.

Hence, an observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.
