Answer:

the moles of oxygen react only 1.05 moles

Explanation:

because the formula of methane is CH4 so it has 10 molecule so 10.5 ÷10 =1.05

The correct answer to this open question is the following.

Unfortunately, you did not provide the sketch or the photo that shows what Francis is doing. So we do not know what you are talking about.  

However, trying to help you, we did some deep research and can comment on the following.

If the photo shows a plan under the light of a lamp, moving towards the lamp direction, then tropism is Francis most likely investigating is phototropism.

To better understand the concept, Tropism is the movement of a plant towards the direction of an influence exerted on it. This means that an external factor is introduced in order to make the plant grow through an external influence.

So when we use the term phototropism, this means that the plant responds to the direction of the source of light and grows in that direction. That is what Francis is using in his science experiment.

Answer:

phototropism

Explanation:

Answer:

Explanation:

A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.

B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene. 

C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

Lung air sacs are surrounded by small blood veins, and a thin membrane allows for the exchange of gases (option C).

The chemical process that generates energy and powers the metabolisms of most living things, respiration, depends heavily on oxygen. The oxygen in the air that we breathe is essential for the survival of humans and many other animals.

The sole sort of atom in oxygen makes it a chemical element, which is a substance. An oxidizing agent has eight atoms in its nucleus, as indicated by its atomic number of 8, which is represented by the letter O in its official chemical formula. At room temperature, oxygen is a gas that lacks all other flavors, smells, and colors. Molecular oxygen can be found in nature.

Answer:

1. Mr. Shepherd maintain a relative constant body temperature by preventing loss of heat.

2 This process is called HOMEOSTASIS

Explanation:

Homeostasis is the process whereby living organisms maintain a stable internal environment despite changes in conditions to the external environment. It is necessary that the body undergoes this process in order to guarantee survival.

According to this question, Mr. Shepherd is at a football game on a cold day. This means that in order to maintain a stable internal temperature, the body must preserve heat in the body and prevent its loss via sweating.

The regulation of body temperature is maintain fundamentally by the thermoregulatory center located in the preoptic region of the hypothalamus, this process is called homeostasis, which is the balance that occurs in the internal environment.

The main thermoregulatory mechanism is the increase or decrease in blood flow to the skin, through vasodilation and vasoconstriction.

Therefore, we can conclude that the maintenance of body temperature is closely related to another important indicator, the internal environment (homeostasis).
