A long note about Artificial Pacemaker (I WILL MARK YOU AS BRAINLIST PLS HELP)
Answer:
A cardiac pacemaker is a medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chamber to contract and therefore pump blood by doing so this device replaces and/or regulates the function of the electrical conduction system of the heart. The primary purpose of the pacemaker is to maintain an adequate heart rate, either because the heart’s natural pacemaker is not fast enough or because there is a block in the heart’s electrical conduction system.

There are about 4 million red blood cells (RBCs)
in a microliter of human blood. An adult human
has around 5 liters of blood in their body. Based
on these numbers, roughly how many red blood
cells are in the body in scientific notation?
Answer:
20,000,000,000
Explanation:
Adult humans have roughly 20–30 trillion red blood cells at any given time, constituting approximately 70% of all cells by number. Women have about 4–5 million red blood cells per microliter (cubic millimeter) of blood and men about 5–6 million; people living at high altitudes with low oxygen tension will have more.
Smooth muscle contractions are typically characterized as:
O voluntary
O somatic
O motor based.
O involuntary
Voluntary Muscles.
[tex] hope \: it \: helps \: please \: mark \: \\ me \: as \: brainliest[/tex]Smooth muscle contractions are typically: Involuntary ( option 1 )
Smooth muscle contractions are made possible when myosin and actin filaments slide over each other and the hydrolysis of ATP provides the energy for this action. smooth muscle contractions occur without the interference of an individual hence is it an involuntary action.
Muscle that can be said to be voluntary is the skeletal muscle while Cardiac muscles are also classified as involuntary muscles

In this module you will learn to identify the plant parts and their functions. Why do you think plants are important in our life?
Answer:
: Green Plants are the sources of energy for all oraganism. They trap the solar energy and convert it into chemical energy in the form of food(starch)and they give off oxygen. if all green plants would not be there then all the herbivores will die due to starvation and so will the carnivores.
:Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe.
Also many plants are very useful in field medicine.
:Roots of plants and trees reduce soil erosion by holding the soil firmly.

Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).
Biological macromolecules are organized into four (4) main categories and these includes;
I. Nucleic acid: it comprises of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which are the genetic codes (blueprints) for living organisms.
II. Carbohydrates: it is contained in energy-giving foods and it aids the functioning of the muscles, nervous system and other organs found in the body.
III. Proteins: it contains amino acids and it is responsible for maintaining the functioning of the body system.
IV. Lipids: these categories of biological molecules is mainly made up of fats and it is responsible for providing the body with long-term energy.
In Biology, lipolysis is a process which typically involves the breakdown of fat into glycerol and fatty acids, so as to produce the energy required by a living organism. Thus, the fatty acid that are produced during these process are released into the bloodstream of the living organism and transported to the tissue that uses the energy.
Generally, the breakdown of fat produces more than twice the amount of energy than the breakdown of carbohydrates because it provides long-term energy that is required by the body of living organisms to function properly.

Excretion in flowering plant and excretion
humans in a table form.
Answer:
Four differences between excretion in flowering plants and excretion in human are as follows.
(1) In a plant, oxygen is a by-product of excretion whereas, in animals, urea is produced.
(2) Plants do not have exclusive excretory organs while humans do have them.
(3) Plants tend to shed their parts while excreting while humans do not tend to shed their organs for the process.
(4) Some solid waste products of plants are stored in their dead cells whereas, in humans, all excretion product gets passed out of the body.

What are ketones?
How can you tell if there are ketones in urine?
Under what conditions would the body make excess ketones that appear in the urine?
Answer:
if your cells don't get enough glucose, your body burns fat for energy instead. This produces a substance called ketones, which can show up in your blood and urine. High ketone levels in urine may indicate diabetic ketoacidosis (DKA), a complication of diabetes that can lead to a coma or even death.

Una galleta con chispas de chocolate y un helado con fresas, son ejemplos de:
A. Sustancia
B. Compuesto
C. Mezcla homogénea
D. Mezcla heterogénea
Una galleta con chispas de chocolate y un helado con fresas, son ejemplos de mezclas heterogéneas.
Una mezcla heterogénea está compuesta por dos o más sustancias diferentes, en donde es posible distinguirlas fácilmente ya que es una composición no uniforme. Las sustancias que lo forman no son representadas por ninguna fórmula química pero a su vez tienen sus propiedades particulares.
No se trata de una mezcla homogénea ya que la misma se trata de una mezcla uniforme en donde sus componentes no se pueden distinguir fácilmente. Esto significa que toda la mezcla posee las mismas propiedades. Unos ejemplos de mezcla homogénea son el agua de mar, café con azúcar, cerveza, etc.
Tampoco se trata de una sustancia ya que la misma se trata de cualquier componente que posee ciertas propiedades físicas y químicas estables que pueden detectarse fácilmente. Está compuesto de moléculas o átomos iguales, siendo ejemplos de sustancias: oxígeno, nitrógeno, etc. Además, no es posible separar una sustancia mediante ningún método.
Por último, tampoco se trata de un compuesto ya que el mismo se trata de una mezcla de distintos elementos que se combinan en una reacción, que pueden representarse mediante una fórmula química y que no pueden separarse o romperse salvo por procesos químicos puntuales. Es decir, está formado por moléculas con átomos distintos pero en la misma proporción, y siempre se trata del mismo tipo de molécula. Por ejemplo, el agua, que está formada por un átomo de oxígeno y dos de hidrógeno (H2O).
Para concluir, podemos decir que un elemento está formado por un solo tipo de átomo. Una sustancia se encuentra formada por mas de un elemento unido mediante un enlace químico. Un compuesto está formado por elementos distintos unidos, y una mezcla está formada por sustancias que pueden ser iguales o no, pero en cantidades aleatorias y que pueden separarse. En una mezcla homogénea, la composición es la misma en cualquier parte, y en la mezcla heterogénea la composición es variante.
