How does the cardiovascular system deliver nutrients and oxygen to all cells in the body via the flow of blood?

Answer:

It is a eukaryotic cell

Explanation:

Eukaryotic cells have membrane-bound organelles (in this case the cell has a nuclear membrane with genetic information).

Bacteria, archaea, fungi, plants, and algae have a cell wall

Answer:

Membrane proteins

The cell membrane is selectively permeable . It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all.

Answer:

The phosphate end and OH end of nucleotide in DNA differ from free nucleotides molecules.

Explanation:

5' phosphate group of one nucleotide and 3'-OH group of another nucleotide combine to form phosphodiester bond which holds the nucleotides in DNA molecule.

The phosphate end and OH end of nucleotide in DNA differ from free nucleotides molecules.

Answer:

Twice.

Explanation:

If a soil with 3% moisture has twice the rate of erosion as compared to the soil having 7% moisture if both experience same speed of wind i. e. 15 m/s. This is because moisture held the particles of soil tightly with each other and prevent erosion in the soil so if the moisture becomes half in the soil then the rate of erosion is twice or doubled at constant wind speed.

Answer: The transformation of energy from eating the meal to the five mile run is from

Chemical energy --> kinetic energy--> thermal energy.

Explanation:

In nature, energy exists in various forms. These forms are inter- convertible, that is, one form of energy can be transformed into another form. Such energy transformations are governed by the laws of thermodynamics.

The first law of thermodynamics states that energy cannot be created or destroyed but may be transformed from one form into another.

Living organisms which comprises the biotic components of an ecosystem are energy converters. For example:

--> plants convert solar energy into chemical energy during photosynthesis

--> animals convert chemical energy into kinetic energy when they move about. This in turn is lost as heat energy when highly complex organised food molecules are broken down.

From the question, the student ate a nutritious meal ( CHEMICAL energy) which is converted to KINETIC energy as she took a five miles run ( as she worked). 'Work' here refers not only to physical activities but also to the various metabolic processes necessary to maintain life. And each time work is done, kinetic energy is converted to heat( thermal energy)

C- The sequence (order) of nitrogen bases

Explanation:

Explanation:

The Anaphase stage is the shortest phase of mitosis. During this phase, disjunction occurs, and migration of sister chromatids away from each other to the poles of the cell occurs, leading to the formation of daughter chromosomes. Molecular motors use ATP to shorten the spindle fibers attached to each sister chromatid

Cell division, torso axis formation, tissue and organ development are all part of development, and cell differentiation refers to acquiring a final cell type identity.

The process by which a parent cell divides into two daughter cells is known as cell division.

Cell division is usually part of a larger cell cycle during which the cell grows and replicates its chromosomes before dividing.

Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.

Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.

Multicellular organisms form in a variety of ways, including cell division and the aggregation of many single cells. Colonial organisms form when many identical individuals band together to form a colony.

Thus, this way, organisms with many cell types develop from a single cell.

The form correct pairs can be matched with the parts of fruits as;

The epicarp, which is the outermost layer, the mesocarp, which is the middle layer, and the endocarp, which is the inner layer enclosing the ovaries or the seeds, are the three separate layers that make up the pericarp in fleshy fruits.

The fruit's exterior surface is made up of the exocarp, the fruit's top layer. The tissue between the exocarp and endocarp is called the mesocarp. The innermost layer, called the endocarp, is situated just outside the seed coat.

Answer:

h - height

Explanation:

gravitational potential energy = m * g * h

m stands for mass. Mass doesn't change in physics

g stands for gravitational acceleration. It is a constant.

h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.

In the equation gravitational potential energy = mgh, the variable that is changing as the skater moves up and down the track is the variable h, which represents the height or vertical position of the skater.

As the skater moves up the track, the height increases, resulting in a higher value for h. Conversely, as the skater moves down the track, the height decreases, leading to a lower value for h.

The other variables in the equation, m (mass) and g (acceleration due to gravity), typically remain constant unless specified otherwise. Therefore, the changing variable in this equation as the skater moves up and down the track is the height (h).

Answer:

Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food. Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things.  Without amino acids, plants cannot make the special proteins that the plant cells need to grow. Without enough nitrogen, plant growth is affected negatively.

Answer: C....Convection currents play a role in the movement of Earth’s inner core

The statement which is not correct with regard to convection currents is as follows:

Thus, the correct option for this question is C.

Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.

The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.

Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.

Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.

Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.

Therefore, the correct option for this question is C.
