Answer:

The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.

Explanation:

Answer:

All living things are made up of cells.

The cell theory is a widely accepted principle of biology. Scientists that contributed to the cell theory include; Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.

The cell theory states that;

All living organisms are made up of cells and they may be unicellular or multicellular.

The cell is the basic structural and functional unit of life.

Cells arise from pre-existing cells.  

Answer:

Honey > Water > oil > air

Explanation:

Heavy density will sink and less heavy density will float

So,

Density of honey is highest so, honey will sink

than,

Density of water is higher so, vegetable oil will float

Density of oil is higher so, air will float

Honey > Water > oil > air

Answer:

D. Reflected vs Absorbed

Explanation:

Answer:

The hydrophilic part of the polypeptide chain would be oriented towards the surrounding water while the hydrophobic portion would be arranged away from the water and would make the hydrophobic interior resulting in coiling of the polypeptide chain. The body proteins assume the shapes to organize their hydrophobic parts away from the watery fluid.

Explanation:

Amino acids are the monomers of proteins. Each amino acid, present in proteins, has a central carbon atom. Four functional groups are attached to the central carbon atom of amino acid. These are the carboxyl group (COOH), amino group, a hydrogen atom (H) and a side chain (called R group). Amino acids differ from each other for the side chain present in them. Based on the nature of the side chain, amino acids are hydrophobic or hydrophilic or neutral. Sidechains of some amino acids are charged and have positive or negative charges on them.

The extracellular fluid of the body is a watery medium. Blood also has liquid plasma that is 99% water. The intracellular fluid, called cytosol, is also a water-based liquid.  

The hydrophilic side chains of the amino acids interact with the watery surroundings. They can make hydrogen bonds with the water. The charged hydrophilic R groups make electrostatic interactions with the surrounding medium. The hydrophobic R groups of the amino acids tend to arrange themselves away from the watery medium. This makes the part of the polypeptide chains with hydrophobic amino acids to fold so that these R groups are oriented away from the water.

Similarly, when a long polypeptide chain is dropped in the water, the hydrophobic R groups are arranged away from the water while the hydrophilic ones are arranged towards the surface of the chain facing the water. It is done to adopt a stable shape where maximum attraction forces are established.

Answer:

[tex]\boxed {\tt Golgi \ apparatus}[/tex]

Explanation:

After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.

In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.

So, the correct answer is Golgi apparatus.

Golgi apparatus

The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.

Answer:

The narrator uses that phrase because the pieces of the skin and face feathers have to come together as one to create a human head so they would be fitting together like puzzle pieces.

Explanation:

Answer:

The human face doesn’t form all at once. It requires many divisions of cells. As the cells divide, they eventually piece together to form a human face.

Answer:

Receptors and enzymes are both located in the cell membrane. Receptors and enzymes are both proteins that can cause a reaction or response. Receptors and enzymes both speed up chemical reactions. Receptors and enzymes do not have any similarities.

Explanation:

Enzymes are known as biological catalysts. They speed up a chemical reaction taking place inside the body. Receptors can be defined as the chemical structures that transduce and receive signals.

The similarities between enzymes and receptors are as follows:

Both are proteins and both are crucial for the completion of different functions in the body.

Your welcome

According to the Charles darwin theory of natural selection, genetic diversity best allow a species to survive environmental changes.

Natural selection is the procedure via which populations of living organisms acclimate and modify.

Individuals in a population are naturally variable, indicating that they are all distinct in some manner. This divergence means that some individuals have characteristics better suited to the environment than others.

Natural selection leads to evolution.

Thus, genetic diversity best allow a species to survive environmental changes.

Answer:

Perspiration provides homeostasis to the internal condition of temperature balance.

Explanation:

Perspiration occurs as a consequence of the increase in environmental temperature, which at the same time produces an increase in body temperature.

The high body temperature produces a stimulus that reaches the thermoregulation center of the central nervous system, which produces a response transmitted through the sympathetic nervous system, causing the sweat glands to increase the production of sweat.

The sweat that covers the skin is capable of acting as a physical agent to lower the temperature, a mechanism of thermal regulation that contributes to temperature balance.
