What is the reason for the increased number of drug resistant bacteria being found in hospitals?
Answer: This rise is related to their natural resistance to most commonly used antibiotics and their capacity to acquire resistance to other antibiotics either by mutation (penicillins) or by transfer of resistance genes on plasmids and transposons (aminoglycosides and glycopeptides).
Explanation:
Multiple sclerosis (MS) is a disease that affects the nerve cells of the brain and the spinal cord. Some of the symptoms of MS are chronic pain, pins-and-needles sensations, muscle weakness, and visual disturbances. Study the image, and then explain the cause for these symptoms.
Answer:
Nerve cells and axons are the way we transmit motor and sensory signals. The cells and axons are coated with myelin a.k.a.(myelin sheath) Myelin allows smooth transition of signals to and from motor and sensory pathways. In multiple sclerosis the myelin sheath is irreversibly damaged. The damage to the myelin interrupts the normally smooth transmission of signals. The damage leads to pins and needles sensations(paresthesias), muscle weakness secondary to poor motor signal transmission, vision is no different as the sensory signal is impeded from transmission secondary to lack of myelin sheath
Explanation:
Answer:
According to the image, the myelin sheath in a person with multiple sclerosis wears away. This damage hampers the ability of the nerve cells to transmit impulses as fast as they can. This inability results in symptoms such as visual disturbances. It also causes chronic, dull pain. These symptoms wouldn’t exist if the myelin sheath were intact. (this is the sample answer they gave me)
Explanation:
suggest two factors other than the rate of nitrogen fixation that may affect the avality of nitrogen in the marine ecosystem
Answer: run off from land/rivers and phytoplankton blooms
Explanation:
Nitrogen, particularly as nitrate is easily leached from soil. Human agriculture relies on fertilisers with significant nitrate content that applied at levels higher than it can be used. The balance end up as runoff, much of which ends up in
The two factors that are other than the rate of nitrogen fixation that fit the marine ecosystem are runoff from the land or rivers and the phytoplankton blooms
Waht is nitrogen fixation ?Nitrogen fixation refers to the chemical process by which molecule N2 has a strong Tripple covalent bond and in the air, it gets coveted into NH3 or a related nitrogenous compound that is typically in soil or aquatic system.
The fixation is essential for life as inorganic nitrogen compounds are needed for the biosynthesis of nitgen-containing organic compounds like amino acids.
As nitrogen is easily found in soil and can be added by fertilizers it ends as runoff and damages the ecosystem.

Why does the body produce carbon dioxide if it is harmful to the human
body?
Answer:
Carbon monoxide can kill. The gas forms when there is not enough oxygen to produce carbon dioxide -- essentially when the carbon in fuel is not burned completely. Carbon monoxide prevents oxygen in the blood from being carried throughout the body, causing asphyxiation.

Cytotoxic T cells recognize and kill host cells infected by viruses. They recognize these cells by the foreign antigen displayed on the host cell’s:_________.
A. MHC I molecules
B. MHCII molecules
C. toll like receptors
Answer:
The correct answer is - A. MHC I molecules
Explanation:
Major histocompatibility complexes (MHCs) are presented to different T cells to identify the antigen on the host or infected cell. There are two MHCs - class I and class II. The class I MHC presents to cytotoxic T cells while MHC II to helper T cells.
A cytotoxic T cell only binds to the infected cell displays the foreign antigen such as viruses on the infected cell surface in order to recognize and kill the cells.

The correct chronological sequence of how the endocrine glands are activated during the alarm reaction stage is
Answer:
The correct sequence is: Hypothalamus, Pituitary, Adrenal
Explanation:
The endocrine system comprises of cells, tissues, and organs that discharge hormones as an essential or auxiliary capacity. The endocrine gland is the significant part in this system. The essential capacity of these ductless glands is to discharge their hormones straightforwardly into the encompassing liquid. The interstitial liquid and the veins at that point transport the hormones all through the body. The endocrine system incorporates the pituitary, thyroid, parathyroid, adrenal, and pineal organs

Ground tissue
stores extra food
supports the plant
is found in plants and animals
Omakes up the majority of a plant
Dis responsible for photosynthesis
Answer:
stores extra food
is responsible for photosynthesis
supports the plant
makes up the majority of a plant
Explanation:
Ground tissues are one of the three types of plant tissues (others being dermal and vascular). They are composed of cells as follows: parenchyma, collenchyma, and sclerenchyma. These three cells that make up the ground tissues perform different functions in the plant cell.
- Parenchyma functions in photosynthesis and storage of extra food (carbohydrates) in the cell.
- Collenchyma functions in the support of young regions of the plant
- Sclerenchyma, which has the thickest cell wall, functions mainly in the strengthening/support of the plant cell.
Also, among the three tissue types in a plant, ground tissues make up majority of the plant cell.

A.
Unequal heating creates a pressure difference.
B. Air flows from a high-pressure area to a low-pressure area.
C. Cooled air sinks toward the surface, creating a low-pressure area
D. Warmed air sinks, creating a high-pressure area as it falls.
above it.
Answer:
D. Warmed air sinks is not a normal convection cycle outcome
Explanation:
Warm air is buoyant and rises. Cold air is dense and sinks.
Think of fog in the air. Fog forms in low/cool areas, as the sun comes out and warms up the atmosphere the upper atmosphere, heat flows to cold so upper atmosphere air displaces the fog.
Space heating, the steam or hot water radiators are placed along the floor typically causing convection of warm air to rise up over windows and cold walls, breaking up cold air drafts.

What is a ribososme?Ribosomes, also called Palad granules (after their discoverer George Palade, for their granular structure), are macromolecular machinery found in all cells that perform biological protein synthesis (mRNA translation).Ribosomes join amino acids in an order determined by the codons of the messenger RNA (mRNA) molecule to form a polypeptide chain. Ribosomes are composed of two major components, the large and small ribosomal subunits.Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).Ribosomes and related molecules are also known as the translational apparatus.The ribosome is a ribonucleoprotein complex because it is composed of a complex of RNA and protein.Each ribosome is composed of smaller (30S) and larger (50S) building blocks called subunits.
