Answer:
Habitat Destruction
Explanation:
Habitat destruction refers to the act of destruction of natural habitats of other living beings to use the land for human use. A lake is habitat for aquatic organisms and serves as water reservoir. When it is drained to vacate the land and to use it for new housing development, the process is called as habitat destruction.
what chemical compound is crucial to marine life and how it is disappearing
The answer is nitrogen. It is usually regarded as a growth-limiting factor for primary producers such as phytoplankton. It is usually taken up in the ‘fixed’ form of ammonium. It is converted from dissolved nitrogen gas in ocean surface to a ‘fixed’ form by particular microbes. Due to increasing global temperatures, as a result of global warming, the ocean temperatures have increased hence oceans hold less dissolved oxygen than they used to. The low oxygen concentration in the oceans induces the loss of nitrogen from oceans through increased activity of micro-organisms that are significant in denitrification. This rate becomes higher than that of nitrification that fixes nitrogen in the oceans.
In a _____________ wave, vibrations are perpendicular to the direction of the wave motion. In a _____________ wave, vibrations are parallel to the direction of the wave motion.
Answer:
1. Transverse wave
2. Longitudinal wave
Explanation:
In a transverse wave, vibrations are perpendicular to the direction of the wave motion. In a longitudinal wave, vibrations are parallel to the direction of the wave motion.
In the transverse wave, crest and trough are the parts of a wave. The crest is a part where the displacement is maximum. While the trough is the part where the displacement is minimum.
In the longitudinal wave, the compression and the rarefaction are the part of a wave. In compression, the particles are very close to each other. While, in rarefaction, the particles are far apart.
Why are antibiotics frequently added to sabouraud agar for isolating fungi from clinical samples?
Antibiotics such as cycloheximide are frequently added to sabouraud agar for isolating fungi from clinical samples because most fungi grows and multiply slowly at least compared with bacteria that grows rapidly after 24hours. Incorporation of antibiotics into the agar will prevent the growth of bacteria and also other environmental fungal such as Aspergillus spp.

What creates a magnetic field?
A magnetic field is created by moving electrical charges. Thus, the correct option for this question is B.
What do you mean by Magnetic fields?The magnetic field may be defined as a type of vector field that significantly describes the influence of a magnet on moving electric charges, electric currents, and magnetic materials. It involves the force of magnetism across it.
The magnetic field is generally produced by the action of magnet or electric charges in motion. The magnetic field has defined as a region around a magnetic material or moving electric charge through which the force of magnetism significantly acts over it. Magnetic fields are illustrated by utilizing magnetic field lines.
Therefore, a magnetic field is created by moving electrical charges. Thus, the correct option for this question is B.

What does absorption mean?
A - breakdown of molecules
B - enzyme activity on nutrients
C - network of chemical reactions that occur in the body
D - process of assimilating
Absorption is the biological process where digested nutrients are taken into the bloodstream, mainly occurring in the small intestine.
Explanation:Absorption in the context of biology, particularly the digestive system, refers to the process in which substances pass into the bloodstream or lymph system to circulate throughout the body. After food is broken down into small nutrient molecules through mechanical and chemical digestion, the molecules are absorbed by the blood. This process primarily takes place in the small intestine, where nutrients are assimilated into the body to be used for energy, growth, and repair.
Which of the following can be cofactors?
organic molecules
inorganic molecules
anions
cations
Answer:
The correct options are: organic molecules and cations
Explanation:
Cofactors are the non-protein ions or molecules that combine with the inactive enzyme, called the apoenzyme to form the holoenzyme.
Cofactors can be classified into two categories: 1. the inorganic ions or the metal ions and 2. the coenzymes.
Coenzymes are the complex organic molecules that are of two types: 1. the cosubstrate; 2. prosthetic group
Therefore, Cofactors can be either inorganic metal ions or organic molecules.

which of the following is true ? 1. All populations in an ecosystem form the community. 2. A habitat represents all the biotic factors in an ecosystem. 3. The amount of nutrients in soil is an example of a biotic factor. 4. Only one population can live in a habitat at a time
The head of a giraffe is 2.0 m above its heart and the density of the blood is 1.05 103 kg/m3. what is the difference in pressure between the giraffe's heart and head? (fortunately, a giraffe's neck has a special circulatory system to adapt to this neck length, producing an even flow of blood to the head.)
The difference in pressure between the giraffe's heart and head is :
20.58 kPa Position of Giraffe head in relation to its heartGiven that the head of the giraffe head is placed at a higher position the blood pressure in the head will be higher than the blood pressure in the heart. and
Pressure in the Giraffe is directly related to ; density , gravity and height of the giraffe
Therefore pressure = ρ*g*h
= 1.05 * 10³ * 9.8 * 2
= 20580 pa = 20.58 kPa
Hence we can conclude that the difference in pressure between the giraffe's heart and head is 20.58 kPa.

After replication, ____ identical molecules of _____ are produced. A gene is a sequence of _____ in a molecule.
Which other system in the body works closely with the kidneys to regulate arterial blood ph?
The correct answer is the respiratory system.
The pH of the extracellular fluids (blood) can be controlled by separately regulating the partial pressure of CO2, which determines the carbonic acid concentration via respiration and the bicarbonate ion concentration in the extracellular fluids via renal system. Control of the carbonic acid concentration in the blood is achieved by changes in the rate and depth of breathing. Breathing releases or retains CO2 (and thus carbonic acid) in the blood plasma and thus, changes its pH.

In what way do the respiratory and circulatory systems depend on each other
The circulatory system consists of an entire network of blood cells that is being pumped in the entire body throughout and the respiratory system has the main function to exhale carbon dioxide and inhale oxygen for providing energy.
Both circulatory and respiratory systems work together for transportation of oxygen to all the organs and muscles of the body. The heart pumps the oxygen rich blood from lungs and excretes or disposes the waste in the blood to the lungs to breathe and exhale out of the body.

cells that perform a specific function in an organism
Answer:
Cells that perform a specific function:Cell serves as the basic building blocks for building the structure or the body of the living organisms. Now, certain type or specific number of cells come closer and arrange themselves in such a sequence that they need to perform a unique or specific task by making up a whole organ structure.
Explanation:
Example of cells that perform the specific function inside the living organisms body:There are certain cells inside the human body which makes up a single organ and then performs the whole function specifically by themselves, as we have the "myocardial myocytes". These are the specific type of cells which are required for the heart's cardiac muscles to develop or grow in a given pattern. As these cells are specialized for making up or building up of the cardiac muscles which in turns results in the heart structure. And performs the basic function of supply of blood and the required materials i.e nutrients to the different cells and organs.

Coronary heart disease is caused by a buildup of plaque in the arteries that supply blood to the heart. when the flow of blood to the heart is restricted or blocked, the heart can be damaged due to a lack of oxygen. further, if a large piece of plaque buildup gets dislodged from an artery wall, it can get stuck in other arteries throughout the body, including arteries in the brain. for simplicity, let's assume that the artery is cylindrical with a radius of r. the flow rate of a viscous fluid is given by poiseuille's law q=(π/8)(δp/ηl)r4.
