Bulbourethral gland is not part of the secretions that made up the semen.
At the start of the internal section of the male reproductive organ, beneath the prostate gland, is the bulgurethral gland, also known as Cowper's gland. The bulbourethral glands have ducts that drain into the urethra, the tube through which both urine and semen enter. One of the tasks of the gland is to add fluid to semen during the process of ejaculation. They are made up of a network of tiny tubes, or tubules, and between the tubules are sac-like structures made of elastic and muscular fibers that provide the glands their structural support. Mucus, a viscous protein complex, is contained in droplets within the cells of the tubules and sacs. The clear, viscous fluid secreted by these glands serves as a lubricant, a flushing agent that cleans the urethra before to the ejaculation of the semen, and it may also aid to make the semen less watery and offer a proper living habitat for the sperm. The bulbourethral gland serves as a support system for the semen, as seen by the functions listed above.

A red blood cell placed into a container of distilled water will ________ water through the process of ___________.
A red blood cell placed into a container of distilled water will gain water through the process of osmosis.
What is osmosis?Through a cell's partially permeable membrane, water molecules move through osmosis from a solution with a high concentration of water molecules to one with a lower concentration. Red blood cells that are exposed to fresh water swell, and plant root hairs that absorb water are two examples of osmosis. Soak gummy candies in water to see an uncomplicated example of osmosis. A semipermeable membrane is created by the gel in the candies.
When two solutions with different solute concentrations are separated by a semipermeable membrane, osmosis is how the solvent is transported through the membrane. The solvent is transferred from a solution with a lower concentration of solute to a solution with a higher concentration during osmosis.

A traumatic injury to a joint involving the soft tissue (muscles, ligaments, and tendons) is a?
A traumatic injury to a joint involving the soft tissue is called a sprain.
Generally, 'soft tissue' is commonly used to describe muscles, tendons and ligaments. They connect, support and surround the bones. A traumatic injury to the ligament is called a sprain, and a traumatic injury to the muscles and tendons is called a strain.
A sprain or torn ligament occurs when the ligaments in a joint get torn due to a sudden movement so extreme, it exceeds the ligament's normal range of movement. In a joint, ligaments are inelastic, tough collagen fibers that connect two or more bones together.
When a muscle or tendon is overstretched and gets torn, it is called a strain or a pulled muscle. A tendon is a fibrous tissue that connects muscles to bones.
The major difference between a strain and a sprain is that a strain is an injury to the muscles and tendons, while a sprain is an injury to the ligaments. Both injuries are usually mild and can be treated at home using ice, compressions, elevation and rest.

Spirochetes are distinctive in that they have endocellular flagella (axial fibrils, or axial filaments), the number of which varies depending on the species, and ranges from 2 to more than 100 per organism. The axial fibrils wind around the cell body, which is encased in an envelope, each attaching at the opposite end. Typically, spirochetes are found in a watery environment.

If a cell has a relatively high energy need, you would expect it to have _________ mitochondria than a cell with a lower energy need.
If a cell has a relatively high energy need, you would expect it to have more mitochondria than a cell with a lower energy need.
Mitochondrion:- Mitochondrion is a double-membrane-bound organelle, where energy is produced through cellular respiration. It is present in the cytoplasm of a cell and generates adenosine triphosphate (ATP), which is the main energy module of a cell. For this reason, mitochondrion is known as the "Powerhouse of the cell".
If a cell has a higher energy need than others, it is required to have more numbers of mitochondria in that cell, since more mitochondria will produce more energy.
Thus we can conclude that, if a cell has a relatively high energy need, you would expect it to have more mitochondria than a cell with a lower energy need.

C. Theories and laws are the same thing.
D. A theory can never become a law.
The following is TRUE about theories and laws are-
D. A theory can never become law.
All scientific hypotheses are supported by data, are testable, and—most importantly—can be used to forecast the future. Accordingly, ideas never become laws, regardless of how much evidence there is to support them. In actuality, the end purpose of science is the formulation of theories. Any (expressed) law is a theory even though it can contain some truth that can only be derived from facts or another theory.
A theory is something we can only (temporarily) believe in since we are unable to prove it. A law cannot be a fact since it usually has an undefined, universal scope, and we can only collect a limited number of observations, some of which may be nothing more than dreams.
Therefore, I would say that any scientific law is a theory, a conviction, or a hypothesis, and we should anticipate that it will be challenged, improved, or supported by... another (simpler or more compelling) idea.

Compare phasic and tonic contraction in smooth muscles. what tissues and organs are associated with each?
As for comparison, phasic smooth muscle displays rhythmic contractile activity and is associated with gastrointestinal and urogenital systems. While, tonic smooth muscle is continuously contracted and is associated with the large arteries and veins.
Biology routinely distinguishes between smooth muscle tissues that are "tonic" (producing a slow, sustained isometric contraction) and those that are "phasic" (generating a fast transient isometric contraction).
Smooth muscle is divided into tonic and phasic subtypes, but there are some significant functional differences between these muscle types.
The phasic smooth muscles function as unitary muscles, with action potentials spreading from cell to cell, resulting in coordinated phasic contraction, as seen in gut peristalsis.
While,
Tonic smooth muscle behaves as multiple independent units, or motor units, with graded changes in membrane potential of each unit, i.e., without action potential propagation, resulting in graded changes in force (tone).

Sodium reacts explosively with oxygen while iron does not. Which of the following is MOST responsible
for the differences in the chemical reactivity of sodium and iron?
The reason why sodium reacts explosively with oxygen while iron does not is the number of electrons in the outer electron shell.
What is reaction?In a chemical reaction, we have the combination of two substances to form a new substance. Now we have to recall that metals do have an order of reactivity. The metals that are more reactive are found at the top of the activity series and the metals that are less reactive are found below in the series. In this case, sodium is more reactive and is found higher in the series while iron is found lower in the series.
Recall that the activity series is arranged in the order in which the metals are able to loose electrons. The metals that loose electrons more easily occupy the u[per parts of the activity series of metals. Iron lies at the middle position but far below sodium in the activity series of metals.

How do the winds and the ocean distribute heat throughout the biosphere?
a. living planet

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the Sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.
