Biology

gulaghasi [49]3 years ago

A difference between female rats and humans is that a rat's vagina connects to the urogenital aperture and humans do not have a urogenital aperture. The vagina is a short, muscular canal located below the urethra. Additionally, the rat's vagina is much shorter in length than the human vagina. In female rats, the ovaries which produces egg cells and female hormones, are small and located just below the kidneys inside the peritoneal membrane. Also the shape of the uterus in rats is different than in humans. In rats it is Y-shaped and in humans it's a pear shaped organ.

Neurons have special proteins in the cell membranes that control the flow of charged ions. Are these proteins most likely produc
Zielflug [23.3K]

The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.

Explanation:

Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.  

These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.  

Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.

The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.

The time that it would take for the population to double is about 7 years.

<h3>What is population?</h3>

The population of an area refers to the number if people that live in that particular area per time. The life expectancy of a population is increased by adequate sanitation. When there is over  population in an area, it can lead to malnutrition and decreased food production.

A density dependent factor that affects population growth is disease transmission. The countries with the highest populations in the world do not necessarily have the fastest population growth. One factor that has led to lower fertility rates in Europe and North America is educational opportunity for women.

The occurrence which is not a potential consequence of Earth reaching its global capacity is less spread of disease.

Using;

P= Poe^rt

P = 74,000

Po = 37,000

r = 0.1

Hence;

74,000 = 37,000e^0.1t

74,000/37,000 = e^0.1t

2 = e^0.1t

ln2 = 0.1t

t = ln2/0.1

t = 7 years
