Answer:

In the adult organism, mitosis plays a role in cell replacement, wound healing and tumour formation. Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.

Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

Pick one of anna's illnesses and explain all of the ways the illness affected three different body systems.

Rudik [331]

Heart disease affects the cardiovascular system by plaque building up on the artery walls narrowing them making it harder for blood to flow through which could lead to heart attack or probably stroke if the plaque blocks it entirely or maybe almost entirely.

Heart disease may also affect our nervous system for there is higher risk to stroke and it is due to limited flow of blood to the brain and may lead to heart failure which may happen with heart disease that puts the stress on the brain and nerves.

The digestive system is affected by heart disease that causes the system to not get the right amount of oxygen and the nutrients that it needs from the blood.

What is the definition of the length constant? What does the length constant tell you in terms of the electrical signal? Neurons

Furkat [3]

Answer:

The overview of the given problem is outlined in the following section mostly on explanation.

Explanation:

The constant length seems to be a constant value which used to measure the distance between the grade electron density and the neurite through passive electron flow. The larger the quality of the distance constant, the faster the potential goes, throughout consideration of the electronic current.

The electronic replacement through one potential from neighboring areas including its cell will lead with the spatial description by a broad constant of length.
This length decreases with either the size of that same neuron rising.
The length constant, means of characterizing how much continuous current that flows extends until it bursts out from the axon, despite constants of limited period meaning leakier axons.
The resistance of that same membranes should be just as efficient as possible as well as the tolerance of its axoplasm or extracellular media must be weak to enhance the efficient movement of current via an axon.

A student designed an experiment to determine if air temperature had an effect on the rate of photosynthesis in corn plants. Whi

Gnom [1K]

The provided question was incomplete as it lacks the options. However, the correct option for this question is as follows:

an electronic balance to measure the volume of soil in which each corn plant is grown

a graduated cylinder to measure 30 mL of water for each plant daily

a metric ruler to determine the mass of each plant each week

a Celsius thermometer to determine the pH of the soil

Answer:

The correct answer is - a graduated cylinder to measure 30 mL of water for each plant daily

Explanation:

The basic knowledge requires to answer this question, as it is not asking about the photosynthesis or temperature of the air but the tool which is correctly matched, so let's get the answer from the options:

the first option is talking about the electric balance and measuring the volume of soil with it, as wee know electric balance measures mass or force on the pan downwards which is the mass of the substance. so it is an incorrect match.

Graduated cylinder to measure the 30 ml water which is correct as this tool measure volume of liquid or substance.

A metric scale measures distance or length of an object, not the mass thus, it is an incorrect match.

A thermometer measures the temperature, not the pH of a substance so it is also an incorrect match.

What is the endoplasmic reticulum?

Jet001 [13]

Endoplasmic Reticulum is a long piece of membrane inside of the cytoplasm in a Eukaryotic cell. It connects to the Nuclear Membrane as well. It has numerous ribosomes attached as it helps with protein and lipid synthesis. It has both smooth and rough forms, each which do different things inside the cell.
