Answer: The correct answer to the question is option 2
If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.
Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.
Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.
Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.
This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.
The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid
Ligaments connect one bone to another bone. Therefore, they allow a joint to form, because joints are where two or more bones connect.
Take your knee joint for instance (***see attached pic***). The knee joint is formed by the connection of the femur (your thigh bone), the tibia (your shin bone), and the fibula (the other long bone in your lower leg). In order for all of these bones to connect there are many ligaments in the knee joint that keep the bones connected and in place. A well known example of one of these ligaments in the knee joint is the ACL (anterior crucate ligament), which is commonly torn in sports, namely football. Most people have heard of this ligament because it receives a lot of media attention since tearing it can greatly alter or even end professional athletes' careers.
Here is a diagram I found online if it helps!
Answer:
les glandes produisent deux produits essentiels :
-gamètes. les mâles produisent du sperme et les femelles produisent des ovules (œufs). la formation des gamètes dépend d'un type particulier de division cellulaire appelé méiose
-hormones sexuelles. ces hormones stéroïdes - principalement la testostérone chez les hommes, les œstrogènes et la progestérone chez les femmes - jouent un rôle vital à la fois dans le développement et la fonction des organes reproducteurs et dans le comportement et les pulsions sexuelles. ces hormones influencent également la croissance et le développement de nombreux autres organes et tissus du corps
