Biology
1 answer:
suter [353]3 years ago
8 0

1) The first reactant is incomplete.


2) The reaction is a combustion reaction and it is easy to infere that it is the combustion of the alkane with 3 carbons.


3) The general chemical formula of the alkanes is

               C_nH_{2n+2}


4) Hence the equation is:


C_3H_8+O_2->H_2O+CO_2


5) The name of the alkane is propane, so the word equation is:


            propane + oxygen → carbon dioxide + water


6) The equation is unbalanced. This is the balanced equation:


            C_3H_8+5O_2->4H_2O+3CO_2


7) It is, as the combustion of any hydrocarbon, a redox (reduction-oxidation) reaction, where the carbon is oxidized and the oxygen is reduced.


8) This kind of reactions release a lot of energy.

Morgarella [4.7K]

The hypothalamus __________.

a) influences the function of only one lobe of the pituitary gland.

b) synthesizes all of the hormones produced by the pituitary gland.

c) regulates both reproduction and body temperature.

d) produces only inhibitory hormones.

Answer:

C) Regulates both reproduction and body temperature.

Explanation:

The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus.

The hypothalamus’ main role is to keep the body in homeostasis as much as possible.

Homeostasis means a healthful, balanced bodily state.

The hypothalamus acts as the link between the endocrine and nervous systems to achieve this. It plays a part in many essential functions of the body such as: body temperature, thirst, appetite and weight control, emotions, sex drive, blood pressure and heart rate, production of digestive juices and balancing bodily fluids.

How are mean and median alike?how are they different?
Vlada [557]

Answer:

Mean is the average you'll get when you add all your numbers then divide by the number of numbers you have. On the opposite side, median is the middle number within your list of numbers. If there isn't a middle number, take the two middle numbers and add them. Now, for how they are alike, I'm not so sure :'), but my closest guess would be they are fairly close together.

Sorry it's so long, hope I helped you :')

A woman without hemophilia marries a man with hemophilia they have a daughter with hemophilia what is the genotype of the mother
Alecsey [184]

Answer:

Mother- XXH

Father- XHY

Explanation:

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.
