Answer:

B.) water mold

Explanation:

The water mold is a filamentous fungus like organisms that lives in  brackish water, fresh water or wet soils. They are saprophytic, that is, they live on dead organisms. Their reproduction is usually by motile asexual spores (zoospores).The zoospores are of two types namely pear-shaped with apical flagella and kidney-shaped with two flagella on the concave side. Water mold are usually identified by their zoospores.

Answer:

d. the cells in primary cell cultures do not divide.

A key difference between primary cell cultures and secondary cell lines is that the cells in primary cell cultures do not divide.

hope it helped you

Explanation:

The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.

Answer:

Cells enter the G0 phase to stop dividing.

Answer:

Time is a very important variable in geology because the exact timing of spatially separated events allows us to reconstruct the surface and surface conditions of the ancient earth. Geologic time spans are considerably more difficult to comprehend than historical time spans because they are so incredibly long.

One reason is so that we can fully understand how geological processes that seem impossibly slow can produce anything of consequence. For example, we are familiar with the concept of driving from one major city to another: a journey of several hours at around 100 km/h. Continents move toward each other at rates of a fraction of a millimetre per day, or something in the order of 0.00000001 km/h, and yet, at this impossibly slow rate, they can move thousands of kilometres. Sediments typically accumulate at even slower rates — less than a millimetre per year — but still they are thick enough to be thrust up into monumental mountains and carved into breathtaking canyons.

Another reason is that for our survival on this planet, we need to understand issues like extinction of endangered species and anthropogenic (human-caused) climate change. Some people, who don’t understand geological time, are quick to say that the climate has changed in the past, and that what is happening now is no different. And it certainly has changed in the past. For example, from the Eocene (50 Ma) to the present day, Earth’s climate cooled by about 12°C. That’s a huge change that ranks up there with many of the important climate changes of the distant past, and yet the rate of change over that time was only 0.000024°C/century. Anthropogenic climate change has been 1.1°C over the past 100 years, and that is 45,800 times faster than the rate of natural climate change since the Eocene.

Answer:

A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. The sun provides radiant energy for producer (plant) growth.

Explanation:

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. ... A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

Complete question:

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity?

A.  Slow effector pathways

B.  Modulated effector pathways

C.  Rapid effector pathways

D.  NMDA glutamate receptor pathways

Answer:

D.  NMDA glutamate receptor pathways

Explanation:

The NMDA glutamatergic receptor is a cationic channel receptor modulated by a ligand that allows the transport of Na+, K+, and Ca2+. Under certain situations, it exhibits particular permeability to Ca2+. The receptor has different regions that are susceptible to modulation by endogenous and exogenous agents. The receptor can be found at most excitatory synapses, where it responds to the neurotransmitter glutamate. During synapsis, the presynaptic membrane releases L-glutamate, which is received by NMDA glutamatergic receptor. The receptor plays a regulatory role because activates signaling cascades that depend on calcium.

These receptors are involved in normal synaptic transmission, in a diverse physiological phenomenon, and might be responsible for neurodegenerative processes.

The NMDA glutamergic receptor is characterized by ion flux through transmitter-activated channels resulting in membrane potential.

Transmitter-activated channels are channels through cell membranes which are activated by binding of transmitters.

An example of a transmitter-activated channels is the NMDA glutamergic receptor.

The NMDA glutamergic receptor is a ligand-gated cationic channel that allows calcium, potassium and sodium ions through it.

Answer: The Krebs cycle

Explanation:

The solution is hypertonic to a solution containing 100 mM NaCl and 150 mM urea relative to red blood cell.

The term "hypertonic" refers to a solution that has a higher concentration of solutes compared to another solution. In this case, the solution containing 100 mM NaCl and 150 mM urea has a higher concentration of solutes than the intracellular concentration of the red blood cell, which is 300 mOsM of nonpenetrating solute.

The concept of tonicity is important in understanding how solutions affect cells. When a solution is hypertonic to a cell, it means that there is a greater osmotic pressure outside the cell than inside. In this specific scenario, the hypertonic solution has a higher concentration of solutes (NaCl and urea) than the red blood cell's internal nonpenetrating solute concentration.

As a result, water molecules will tend to move from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell) in an attempt to equalize the concentration on both sides of the cell membrane. This movement of water out of the cell can lead to cell shrinkage or crenation, which occurs when the cell's volume decreases due to water loss.

In summary, the solution containing 100 mM NaCl and 150 mM urea is hypertonic to the red blood cell because it has a higher concentration of solutes than the cell's internal nonpenetrating solute concentration, leading to water movement out of the cell and potential cell shrinkage.

Answer:

The correct answer is - a) biochemical separation, identification, and quantification of mixture components.

Explanation:

Most hemoglobin disorders can be diagnosed by molecular diagnostic techniques such as protein-based techniques like electrophoresis and chromatography. Protein-based methods can diagnose early thalassemia disorders and hemoglobinopathies but in the case of α-thalassemia may be masked in the presence of β-thalassemia.

Molecular genetic testing plays a very important role in the biochemical separation of molecules or components, identification, and quantification of individuals carrying thalassemia and hemoglobinopathies traits and other hemoglobin disorders.

B

Explanation:

What is a divergent boundary:

In plate tectonics, a divergent boundary is a linear feature that exists between 2 tectonic plates moving away from each other.

They can produce rifts, which become rift valleys.

Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that magma rises to fill.

Sedimentary rocks form due to deposition, and accumulation

Metamorphic rocks form in a transformation of existing rock to new rock in a process called metamorphism.

Igneous rocks form through the cooling and solidification of magma or lava.

When the filled gaps of magma cool off, it will produce igneous rocks.

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Explanation:

according to wikipedia!

Digestion is nothing but breaking down of substances into simpler forms, which the body can use. We eat many things and they have very complex compounds, our body cannot use these compounds. So, different parts of our digestive system breaks down different compounds to simpler forms, so that our body can use it for different functions.
