Answer:
Out of all the objects I found I think a car represents a cell the best.
Explanation:
The structure a cars body provides makes it comparable to a cell wall and the car's metal body is also represents a cell wall because it maintains its shape even when it travels at high speeds. The windshield and windows can be compared to plasma membranes, since they protect the inside of the car from invaders (like insects). The gas tank represents the vacuole because it holds the energy source for the car, and the engine represents the mitochondria because it is the power house of the car

During the match, the heartbeat rate of the football fans and players increases. Explain the relationship between the heartbeat rate and the activities of the football fans and the players. (10 marks]
Answer:
Adrenaline
Explanation:
The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.
Which cell type undergoes terminal differentiation?
Stem cells are the only form of cell that can differentiate into more specialized cell types. Therefore, they undergo terminal differentiation.
What is terminal differentiation?As cells migrate to the surface and fully differentiate, i.e., as they keratinize and eventually die, this process is known as terminal differentiation. Terminal differentiation is a method of describing that the cells change their phenotypic traits.
During the process of terminal differentiation, several cell types (such as neurons, skeletal and cardiac myocytes, adipocytes, and keratinocytes) acquire specific tasks and ultimately exit the cell cycle. This process may be observed in neurons, adipocytes, and keratinocytes.

Compare and contrast the immune system and nervous systems
similarities:
The immune system and the nervous system maintain extensive communication, including 'hardwiring' of sympathetic and parasympathetic nerves to lymphoid organs. Neurotransmitters such as acetylcholine, norepinephrine, vasoactive intestinal peptide, substance P and histamine modulate immune activity.

the nerve impulse is an electrical current that travels along dendrites or axons.
Answer:
i think your answer is true! :)
Explanation:
The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.
Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.
A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.
This electrical signal then travels along the axon of the neuron, where it can be transmitted to other neurons or to muscle cells or glands. The speed at which the nerve impulse travels can be influenced by factors such as the diameter of the axon, the presence of myelin sheaths, and the concentration of ions inside and outside of the neuron.Therefore, the mentioned statement about the nerve impulse is true.

1. A rapidly increasing human population is the primary driver behind what
LEADING cause of the loss of biodiversity? (SEV5.a) *
O a. Extinction
O b. Habitat Loss
O c. Pollution
O d. Overexploitation
Answer:
your answer is B. Habitat Loss
Explanation:
What is the #1 cause for the loss of biodiversity?
Habitat destruction
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before.

Answer:
434234
Explanation:
You have recently identified a new toxin. It is produced by a gram-negative bacterium. It is composed mostly of protein, has high toxicity, and is not heat stable. You also discover that it targets liver cells. Based on these characteristics, how would you classify this toxin
Based on the characteristics above, this toxin can be categorized as EXOTOXIN. These toxins (exotoxins) are produced by different types of bacteria.
Exotoxins are a broad category of proteins produced by bacteria that enter host cells in order to alter their physiological properties.
These toxins (exotoxins) can be secreted by Gram-negative bacteria and Gram-positive bacteria.
Examples of exotoxins include botulinum toxin secreted by Clostridium botulinum bacteria, tetanospasmin toxin secreted by Clostridium tetani bacteria, etc.

How do differences between the peaks and valleys of the two graphs demonstrate interactions between these populations?
Answer:
peaks and valleys show population increase and decrease between 2 species or more.
Explanation:
the peaks and valleys are used to show predation hence if there is an increase in prey there will be an increase in the predators and if there is a decrease in prey there will be a decrease in predators therefore creating peaks and valleys in that graph hence demonstrating population interactions between the two species.

How were ozone levels monitored in 1920?
Answer:
I don't know
Explanation:
Sorry.. I really don't know

Help you later
Ozone levels in 1920 were primarily monitored using chemical methods, such as the use of chemical indicators and colorimetric analysis.
Potassium iodide-starch paper was used to detect ozone. When exposed to ozone, these indicators changed colour, letting researchers visually monitor ozone concentration.
Colorimetric analysis was also used. Chemical reagents reacting with ozone changed colour. Ozone concentration connected with colour change intensity. Chemical approaches measured ozone qualitatively or semi-quantitatively. They were easy to use but less precise than modern monitoring approaches.
In the following decades, spectrophotometry and ozone analyzers improved the systematic monitoring and quantitative measurement of ozone levels. These improvements made atmospheric ozone monitoring more precise.

what is Soil erosion..?
Explanation: Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. ... The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related.
