Answer:
MYCOBACTERIA. Mycobacteria are classified as Gram-positive bacteria, but they have features of both Gram-positive and Gram-negative organisms. Pathogenic mycobacteria include the organisms that cause tuberculosis and leprosy and are intracellular parasites, replicating within modified phagosomes of macrophages.
Explanation:
Answer:
As the spores germinate, they produce neurotoxins which, if ingested, leads to paralysis and either respiratory or cardiac failure. A very important disease-causing bacterium in the Western Cape is Mycobacterium tuberculosis, the bacterium that causes TB.

A car goes 65 km/h for 4.5 hours. give the distance covered by the car.
Answer:
292.5 km
Explanation:
In order to solve this problem, we will simply need to multiply the amount of miles driven in an hour, and how many hours.
The formula is: Distance=Speed x Time
In this case:
Speed: 65 km/h
Time: 4.5 hrs
Now, we will just need to multiply. 65 x 4.5 = 292.5
The answer is 292.5 km.

Which of the following factors is most directly responsible for determining stroke volume? 1. Heart rate 2. Venous return 3. Arterial pressure 4. Cardiac contractility
Stroke volume is most directly influenced by cardiac contractility. Stroke volume (SV) refers to the volume of blood that is ejected by the heart from each ventricle with every heartbeat. During systole, this occurs. The formula for calculating stroke volume (SV) is given below: SV = EDV - ESV, where EDV represents end-diastolic volume and ESV represents end-systolic volume.
Factors that determine stroke volume: Stroke volume (SV) is influenced by three key factors:
1. Preload: Preload is the pressure that is exerted on the ventricular walls by the volume of blood in the ventricles at the end of diastole.
2. Afterload: Afterload is the pressure that must be overcome by the left ventricle before it can eject blood into the aorta.
3. Contractility: The ability of the cardiac muscle to contract is referred to as contractility. Contractility can be defined as the intrinsic ability of myocardial cells to generate force and contract against an afterload.
Therefore, from the given options, the most direct factor that is responsible for determining stroke volume is cardiac contractility.

Generally, for fast-dividing mammalian cells, the length of the cycle is approximately 24 hours. G1 is typically the longest phase of the cell cycle. Cells usually remain in G1 for about 1o hours of the 24 hours of the cell cycle. Usually, cells will take between 5 to 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 to 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.
From the given figure, mitosis takes 15 % of the 24 hours cell cycle. Plese see solution below:
24 hours x 15 / 100 = 3.6 hours
when is absent, an anaerobic process called occurs instead, producing atp molecules overall.
When oxygen is absent, an anaerobic process called fermentation occurs instead, producing ATP molecules overall.
During fermentation, cells break down glucose into two ATP molecules and either lactic acid or ethanol, depending on the organism. This process is less efficient than aerobic respiration, which produces up to 38 ATP molecules, but is still necessary in situations where oxygen is not available.
Fermentation is used by organisms such as yeast and bacteria to produce energy and is also used in the food industry to create products like bread, wine, and cheese.

How does the human immune system destroy a pathogen in the body?A. B cells release antibodies that neutralize the pathogen.B. Antibiotics are released by B cells to destroy the pathogen.C. Lymphocytes recognizes pathogens as antigens in the body.D. T cells build immunity to the pathogen by releasing antibodies.
T cells are important to our immune system, but they do not release antibodies. They activate B cells and cytotoxic T lymphocytes to kill cells that are infected. Therefore, D is incorrect.
Antibiotics are not produced by our immune system. They can be found in nature or synthesized in labs. Therefore, B is incorrect too.
Lymphocytes are divided into T and B cells. B lymphocytes release antibodies that will recognize pathogens and bind to them, but T cells doesn't work like that. Lymphocyts does not recognize pathogens and C is incorrect as well.
B cells create antibodies, release them and they will bind to pathogens to neutralize them. Therefore, the correct answer is A. B cells release antibodies that neutralize the pathogen.

The quiver tree grows in desert areas in southern Africa. In recent decades average
temperatures have been rising in southern Africa. Scientists predict that this
warming trend will continue. Quiver trees in the hottest parts of their range near
the equator are dying, but quiver trees at high elevations or in parts of the range
that are farther from the equator are growing and reproducing.
which of these best explains what is happening to the quiver tree population in southern africa oop
Answer: A- Individual quiver trees are unable to adjust to the rising temperatures, and only those in cooler parts of the range will survive
Explanation: the ones that are farther away from the equator are in the coolest parts, but the ones close to it decrease because of them being close to the equator and the heat.
The plants that are found in the quiver tree's cooler climate have a tendency to develop, but they are unable to adapt to the warmer climate.
What is the effect of climate on trees?Some plants reproduce in the warmer regions of the world, like the quiver tree near the equator, where they live and develop. However, after a certain point, they are unable to reproduce because the enzymes are ineffective.
These quiver trees prefer to develop farther from the equator because the cooler temperatures there offer the best conditions for growth.
In light of this, the quiver tree explains why plants that are present in the cooler climate tend to grow but cannot adapt to the more warm-weathered climate.
Therefore, they are unable to adapt to the warmer climate.

Please answer both parts of this question and include a model.
1. Describe this mode of propagation, and draw a model to supplement your description. 2. Explain how it differs from the mode of propagation along the neuron.
1. In passive propagation, as the action potential goes from the start to the end of an axon, it decays or becomes weaker, and it is the most common method of transmitting electrical signals in neurons. 2. It differs from the mode of propagation along the neuron, the action potential is actively propagated along the axon without decay.
A passive signal can be generated by a receptor or by a spike in the membrane potential of an adjacent neuron. In the neuron, an electrical current flows from the dendrite to the cell body, down the axon and into the terminal, causing a change in the potential across the membrane. The current also generates an electrical field that spreads throughout the surrounding tissue, this electrical field, known as the extracellular potential, decays with distance and is much smaller than the intracellular potential. So therefore a passive signal can be detected by electrodes placed outside the neuron.
An action potential is initiated at the axon hillock, propagated along the axon, and terminates at the presynaptic terminal. In the neuron, an electrical current flows from the dendrite to the cell body, down the axon and into the terminal, causing a change in the potential across the membrane.

What process is being used by the cell to move the molecules
The process that is being used by the cell to move the molecules is known as diffusion.
Diffusion is a method that has to do with the movement of substances within cells. It is also a method that's used for small molecules so that they'll be able to cross the cell membrane. It should be noted that the exchange of gas in the lungs of human beings operates through diffusion. For diffusion to take place, gaseous substances will have to go through the cell membrane in order to be able to go into a cell or out of the cell.Diffusion also takes place where there is a spread in particles. Diffusion is a movement from the region of a higher concentration to a low concentration.
