Answer:
O True
Explanation:
Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.

Which type of stem supports giant trees?
A. herbaceous
B. gummy
C. woody
D. leafy
The type of stem that supports giant trees is woody, which is option C. Woody stems are the type of stems that support giant trees, so the correct option is option c.
Woody stems are characterized by their hardness and rigidity, which are due to the presence of wood tissue. This wood tissue provides structural support and allows the stem to grow thicker and stronger over time. Giant trees, such as oak, maple, pine, and redwood trees, have woody stems that enable them to reach great heights and support their extensive branching systems. Herbaceous stems, on the other hand, are softer and more flexible. So the correct option is option C.

Group the following into the appropriate range of measurement.
a. atomic
b. ultramicroscopic
c. microscopic
d. macroscopic
Match each of the options above to the items below.
1. roundworm, algae
2. protozoan, rickettsia
3. herpesvirus, DNA
4. hydrogen atom, glucose molecule
Answer:
Hydrogen atom & glucose molecule --- atomic.
Herpesvirus, DNA --- ultramicroscopic.
Protozoan, Rickettsia - microscopic.
Roundworm and algae --- macroscopic
Explanation:
1) Hydrogen atom & glucose molecule --- atomic.
The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.
2) Herpesvirus, DNA --- ultramicroscopic.
Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.
3) Protozoan, Rickettsia - microscopic.
Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is [tex]( 10^3 \ \ to \ \ 10^{10})[/tex], which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).
4) Roundworm and algae --- macroscopic
Naked eyes can see macroscopic organisms; for example, several types of circular worms and algae can be seen by them.

In humans, nearly 80% of proteins are acetylated on their N-terminal residue, a modification known to be recognized by a specific E3 enzyme, which directs the ubiquitylation of the protein for rapid degradation. Does this mean that all of these proteins would be actively degraded at the same time
Answer:
Yes
Explanation:
Yes this means that all of these proteins will be actively degraded and this is due to the high turnover rate which will ensure that their activity will be under tight control.
The acetylation of the N-terminal of the protein, with the Ubiquitylation of the protein by an E3 enzyme, helps in the maintenance of the homeostasis of protein activity.

As Maria continued to read about common conditions of the nervous system, she realized there was a category of cells called neuroglia that allowed neurons and the nervous system as a whole to properly function. Some of her symptoms seemed to fit with a condition that resulted from a slow destruction of some of these cells.
Correctly match the cell type with the sentence that describes it.
_______are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.
Cell bodies of unipolar neurons are insulated from adjacent cell bodies by .
The ventricles of the brain are lined with _______, which form an epithelial layer that is permeable to cerebrospinal fluid.
The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called_______ .
The myelin sheath of the Central Nervous System is formed by________ .
Axons of unipolar neurons are insulated by_________ , which increase the speed of the electrical impulse.
Mlorogla
Answer:
Astrocytes are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.
Cell bodies of unipolar neurons are insulated from adjacent cell bodies by satellite cells.
The ventricles of the brain are lined with ependymal cells, which form an epithelial layer that is permeable to cerebrospinal fluid.
The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called microglia.
The myelin sheath of the Central Nervous System is formed by oligodendrocytes.
Axons of unipolar neurons are insulated by Schwann cells, which increase the speed of the electrical impulse.
Explanation:
The neuroglia cells are a group of specialized cells that are in the Central and Peripheral Nervous System.
Astrocytes are star-shaped cells that maintain homeostasis in the nervous tissue. They also are part of the blood-brain barrier controlling what can enter the brain and whatnot.
Satellite cells are in the Peripheric Nervous System. They are around neurons and provide nutrients and insulation to neurons.
Ependymal cells are in the Central Nervous System. They line the ventricles and spinal cord's central canal. They are the ones that help in the production and circulation of the cerebrospinal fluid (CSF). They are part of the blood-cerebrospinal fluid barrier, keeping the cerebrospinal fluid clean, and they also absorb the CSF.
The microglia are the macrophages of the Central Nervous System. They phagocytize any pathogen that they detect in the CNS, protecting the neurons.
The myelin sheath is formed by the oligodendrocytes in the CNS and by the Schwann cells in the PNS. Their function is to insulate the axons so that the electrical impulse can travel through them.

A person is taken to the emergency room at Baptist Hospital vomiting, bleeding and with severe diarrhea. He complained of a headache, shortness of breath and body aches. The doctor quickly checked the composition of the patient’s blood plasma, the light-yellow liquid that carries salts and enzymes, and determined he was severely dehydrated. Thus, causing a severe loss of fluid in the blood and an increase of blood cell concentration. The doctor prescribed intravenous liquids (IV) and rest.
Based on the patient’s symptoms and doctor’s initial prognosis, how does dehydration affect a person’s blood flow and blood pressure? SC.912. L.14.36
The patient’s blood viscosity would increase, causing blood flow to increase and blood pressure to decrease
The patient’s blood viscosity would decrease, causing the blood flow and blood pressure to remain at a stable rhythm
The patient’s blood viscosity would decrease, causing the blood flow to decrease and the blood pressure to also decrease
The patient’s blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase
Answer:
The answer is "The patients blood viscosity would decrease, causing the blood flow to decrease in the blood pressure to also decrease".
The correct answer is: The patient’s blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase.
What is Dehydration?When the body loses more fluid than it takes in, dehydration develops. It occurs when the quantity of water and electrolytes (such as sodium, potassium, and chloride) that the body need to operate correctly are out of balance.
Numerous internal processes, such as controlling body temperature, lubricating joints, transferring nutrients, and getting rid of waste, depend on water.
Dehydration causes the amount of fluid in the blood to decrease, which causes the concentration of blood cells and other components to rise.
Blood gets thicker and flows more slowly as a result of this rise in blood viscosity, which is caused by an increase in blood cell concentration.
As a result, the blood flow decreases, and the resistance to blood flow increases, leading to an increase in blood pressure.
Therefore, in the given scenario, the patient's severe dehydration would cause an increase in blood viscosity, leading to a decrease in blood flow and an increase in blood pressure.

A pyramid of biomass shows the mass of all of the organisms in each trophic level of an ecosystem. Look at the biomass pyramid to the right. Based on the data shown, how many kilograms of plant matter would be needed to support the other trophic levels in this ecosystem?
Answer:
90,000
Explanation:
A pyramid of biomass shows the mass of all of the organisms in each trophic level of an ecosystem. From the biomass pyramid to the upright ladder, the kilograms of plant matter needed to support the other tropic levels in this ecosystem is 9000 kg.
In ecology, the biomass pyramid is a graphical representation designed to show the quantity of biological or organic matter observed in an organism.
The ecological biomass pyramid starts with the primary producer which is usually a green plant.
Followed by the herbivores(animals that feed) on the green plants. They are the primary consumers. The carnivores are secondary consumers that feed on herbivores. Then the peak of the pyramid is the tertiary consumers which are called omnivores. (i.e animals that feed on plants & animals).The amount of mass consumed by the primary consumer is equivalent to the total amount of mass in the primary consumer. However, as we go up the pyramid, the mass depreciates.
Therefore, we can conclude that the amount of kilograms of plant matter needed to support the other tropic levels in this ecosystem is 9000 kg.

Answer:
characters
offsprings.
Explanation:
During meiosis, all various genes are separated. The inherited alleles constitute the genotype of the individual.
The transfer of parental to offspring characteristics is called heredity and the heritable features can be predicted.
In the ELISA procedure, first a protein sample is immobilized to a plastic well. Then, the antibody to the protein of interest is added, incubated, and the excess is washed out. Next, the detection antibody (which binds to the primary antibody) is added, incubated, and the excess is washed out. The last step is to add the detection dye (which binds to the detection antibody) to the wells and allow it to incubate. What do you predict the result would look like if you added the detection antibody first, then the antibody to the protein of interest
Answer:
In this ELISA procedure, a sample of protein is immobilized in the plastic well and then antibody for this protein added and incubated, and cleared out. In the given setting detection, the antibody is conjugated with the protein of interest and if the substrate molecule added to the reaction it will produce a colored product by reacting with the enzyme.
No reaction will take place in the well in case of not adding secondary antibody or detection antibody to the reaction and no colored product will be received.
