Answer:

The bone weights more as the bone's thickness is wider for a compacter bone.

Explanation:

Compact, sometimes called cortical bone, thick bone with firm organic soil and inorganic salt in the ossic matrix leaving only narrow gaps in which the osteocytes or bone cells are present. The bone is sometimes called the cortical bone.

Answer:

The bone weighs more as its thickness grows wider, causing a more compact bone.

There is no difference because both potatoes are made of the same type of molecules.

Molecule is a group of two or more atoms that are bound together with the help of some attractive forces. These attractive forces are known as chemical bonds. It is the smallest particle of a substance that has all the physical and chemical properties of that substance.

Atoms have a single nucleus with a positive charge protons surrounded by a cloud of negatively charged electrons. When these come close to each other, the electrons interact with each other and with the nucleus, lowering the total energy of the system, then the atoms bond together to form a molecule.

There are three types of molecules:

1. Molecule of an atom

2. Molecule of an element

3. Molecule of a compound

Thus, there is no difference because both potatoes are made of the same type of molecules.

Explanation:

There are two kinds of water, fresh and salt water. Salt water is found in the ocean, which means that any answer with salt water, or the ocean, in it is not a correct source of freshwater. A, B, and D, all include the ocean as their answer, which means that they all include salt water, so C is the only option left. Lakes, rivers, water vapor, and ice sheets are all examples of sources of freshwater. I hope your sister gets a good grade!

Answer: Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock. rocks that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure.

Explanation:

By correcting genetic flaws, gene therapy aims to prevent or treat hereditary illnesses. The goal of genetic engineering is to alter the genes to give a creature new, enhanced skills. Thus, option D is correct.

The direct altering of an organism's genome through biotechnology is referred to as genetic engineering, sometimes known as genetic modification.

It is a group of scientific techniques used to change the genetic makeup of cells, including the movement of genes within and between species, to produce more advantageous or altogether different creatures.

Applications for genetic engineering include technology, agriculture, and scientific research.

Genetic engineering has been used on plants to enhance the hardiness, nutritive content, and growth rate of crops like potatoes, tomatoes, and rice.

Therefore, innovative best describes genetic engineering.

Answer:

Clear-cutting the rainforest

Explanation:

Density-independent factors of a population are factors that limit the size of a population irrespective of the density of the population.

A limited food source can only be defined by the size of a population, diseases will spread faster in high-density populations, and an increase in the population of a predator will cause a decrease in the population size of the predator's prey.

Clear-cutting of the rainforest means automatic destruction of the habitat of the poison dart frog's population, no matter the population size. Hence, clear-cutting of the rainforest is considered as the density-independent factor in this case.

Answer:

A.) clear cutting the rainforest

Answer:

Everything from the hawk's diet

Explanation:

Mice, rats, shrews, without their main predator, the ecosystem would become unbalanced by the increasing overpopulation of rodents and most likely small snakes that are also on hawks' diet. Another consumer would probably be other animals that eat the hawks' diet. Without a competing consumer, the, let's say snake, population would grow larger.

Answer:

Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion

Answer:

In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The process begins when the enzyme RNA polymerase binds to a region called the promoter.

Explanation:

I took the test lol

Transcription is a particularly important stage in gene expression, since it is the main method by which the cell regulates which proteins are to be created and at what rate.

RNA polymerase, which creates a complementary strand of RNA using a single-stranded DNA template, is the primary enzyme involved in transcription.

Each new nucleotide is added to the 3' end of the strand as RNA polymerase constructs an RNA strand in the 5' to 3' orientation.

The first step in unlocking a cell's genetic code is transcription. Enzymes known as RNA polymerases construct complementary RNA molecules to a section of one strand of the DNA double helix during transcription.

Therefore, In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The RNA polymerase enzyme binds to a region known as the promoter to start the process.

Answer:

Hi There!

Explanation:

1 to 8 km/sec

S-waves are transverse waves. Even though they are slower than P-waves, the S-waves move quickly. Typical S-wave propagation speeds are on the order of 1 to 8 km/sec. The lower value corresponds to the wave speed in loose, unconsolidated sediment, the higher value is near the base of Earth's mantle.

Answer:

Antecubital

Explanation:

In technical anatomical terms, antecubital refers to the area anterior to the elbow—meaning the opposite side. In the human body, the antecubital area is where the humerus (upper arm bone) connects to the radius and ulna bones of the forearm.

The term used to describe the front of the elbow is:  Antecubital  fossa

Antecubital fossa is the term used to describe the front surface of the elbow. this area is important in the human arm because it is the area where the upper arm bone connects with the bones of the forearm ( ulna and radius ).

The name Antecubital fossa is derived from the Latin name Cubitus

During the insertion of IV into the human body or during blood donation, the Antecubital area is very vital because veins can be easily located around the area than any other part of the body.  

Hence in conclusion the term used to describe the front of the elbow is Antecubital.
