Lava flows are typically finer grained (i. e. the rock is made up of smaller mineral grains) than intrusive igneous rocks because the extrusive magma cools quickly so the mineral grains do not have time to grow.

When lava comes out of a volcano and solidifies into extrusive igneous rock, the rock cools very quickly. Crystals inside solid volcanic rocks are small because they do not have much time to form until the rock cools all the way, which stops the crystal growth. Magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture.

C, H, O - elements that are common to biomolecules. If the biomolecule in question is a protein these elements also combine with
vivado [14]

Explanation:

In nature, organic compounds may be large chains of monomers form biological macromolecules which carry out many essential functions in the body. These can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P); they are found in essential organic biomolecules include, proteins, nucleic acids, lipids and carbohydrates.

Proteins are structural support molecules comprised of long chains of monomers called amino acids, joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.  Basic makeup: C, H, O, N, S; polar C, O double bonds and N-H bonding .

alexira [117]

Human placental lactogen( hPL) hormone released during fetal development is primarily responsible for preparing breasts for lactation.

  • Human placental lactogen also stimulates milk ,known as human chorionic somatomammotropin. It's made by the placenta. It gives nutrition to the fetus. secretion of milk is called lactation
  • Mother milk contains all the nutrients that an child needs in the first 6 months of life, including fat, carbohydrates, proteins, vitamins, minerals and water. It's fluently digested and efficiently used. secretion of milk is called lactation. bone milk also contains bioactive factors that compound the child's immature vulnerable system, furnishing protection against infection, and other factors that help digestion and immersion of nutrients. mother milk also protect the child from disease.

If the carrynig capacity of an area is 945, and it is carrying 1.100 individuals, what most likely will happen is that we'll see a decrease in the deers population, until it matches the carrying capacity. This will occur because there wont be enough resources available for all individuals.

Answer:

E.

2 -

The biotic and abiotic limitations are what determine the carrying capacity of a population. Which in other words is simply the amount of living and non-living things that can occupy an area.

If you get a wagon, and say the carrying capacity of that wagon is 100 people, you'll be counting the number of seats (number of people that can sit), the number of people that can stand plus non-living factors such as the space occupied by the seats, metal bars, etc.

Answer:

C.

Sort the terms and phrases as to whether they function in or describe primary growth or secondary growth?
Oduvanchick [21]

Answer:

Explanation:

An increase in length of the shoot and the root is termed to as primary growth of a plant. It occurs as a result of cell division in the apical meristem. Secondary growth is identified by an increase in thickness or girth of the plant caused by cell division in the cambia or lateral meristems.

1) apical meristem- primary growth

2) cork cambium - secondary growth

3) elongation - primary growth

4) provides structural support - secondary growth

5) increases exposure to light - primary growth

6) increases vascular flow - secondary growth

7) growth in thickness - secondary growth

8) occurs in plants that live many years - both primary and secondary growth

9) occurs in plants that live only one year - primary growth

10) lateral meristem - secondary growth

11) vascular cambium - secondary growth.
