Do viruses qualify as a living organism?
Answer:
Viruses are a type of infectious agent that can replicate only inside the living cells of an organism. They are classified as non-living because they do not have many of the characteristics that are typically associated with living organisms, such as the ability to independently carry out metabolic processes such as metabolism and respiration. Unlike cells, viruses do not have a cell membrane or any cellular organelles, and they do not have a true nucleus or any genetic material of their own. Instead, they rely on the cellular machinery of their host to replicate and produce new viruses.However, viruses do exhibit some characteristics that are similar to those of living organisms. They can evolve and adapt to their environment through the process of natural selection, and they can reproduce and pass their genetic material on to their offspring. For these reasons, some scientists consider viruses to be a type of quasi-living entity that exists on the border between the living and non-living worlds.

What is a Pathogen? 4 Types and How They Spread Disease
Pathogen - An organism that causes illness is referred to as a pathogen.
Your body is already teeming with bacteria. However, these organisms only become an issue if your immune system is compromised or if they are able to get into an area of your body that is typically sterile.
Once they enter the body, various pathogens have the power to cause harm.
A host is all that a pathogen requires to live and grow. Once the virus has established a base in the host's body, it avoids the host's immune reactions and makes use of the body's resources to reproduce before leaving and moving on to a new victim.
Depending on the type, there are various ways to transfer pathogens. They can be spread by touching a surface, feces, body fluids, airborne particles, and skin contact.
Pathogen Types -
Pathogens come in a variety of forms, but we'll concentrate on the four most prevalent: viruses, bacteria, fungi, and parasites.
viruses - A segment of genetic code, such as DNA or RNA, makes up viruses, which are further protected by a protein covering. Once you are infected, viruses enter your body through host cells. After that, they replicate by using the elements of the host cell to create new viruses.bacteria - Microorganisms made up of just one cell are called bacteria. They are incredibly diverse, come in a wide range of forms and characteristics, and may exist in almost any setting, including inside of and on top of your body. Bacteria do not always lead to illnesses. Pathogenic bacteria are those that can cause disease.fungi - On Earth, there are countless varieties of fungi. There are just about 300Trusted Source that are recognized to be unhealthy. Almost everywhere in the environment, including indoors, outdoors, and on human skin, is home to fungi.

describe the conclusions mendel reached about inherited traits, using the terms dominant and recessive
Mendel reached at conclusion about inherited trait is when a pair of alleles is heterozygous, the dominant allele expresses itself while the recessive allele does not.
The essential concepts of inheritance were discovered by Gregor Mendel through his study of pea plants. He came to the idea that genes are passed down from each parent as unique, paired units. Mendel looked into how parental genes changed and whether they were expressed as dominant or recessive features in the children. He was aware of the transmission of mathematical patterns from one generation to the next. Typically, Mendel's Laws of Heredity are phrased as follows:
1) The Law of Segregation: A gene pair controls each inherited trait. Only one of each pair of parental genes is present in each gamete as a result of the random distribution of parental genes to the gamete.
2) The Law of Independent Assortment: Different traits are inherited independently of one another because genes for those traits are grouped into distinct groups.
3) The Law of Dominance states that if a gene has two potential variants, the dominant version will be expressed by the organism.

The microtubules of the spindle originate during mitosis in both plant and animal cells from centrosome.
Chromosome separation occurs during mitosis on microtubule-based structures called mitotic spindles. Spindle microtubules originate from centrosomes or spindle pole bodies in the majority of animal and fungal cells.
The pericentriolar material, which is made up of two centrioles and an electron-dense matrix, is the centrosome, the main microtubule-organizing centre (MTOC) in eukaryotic cells (PCM). The centrosome's ability to nucleate, anchor, and release microtubules (MTs) is what allows it to organize MT arrays, like the mitotic spindle.
The duplication of centrioles makes sure that each daughter cell receives two centrioles. It happens in four stages that follow one another: the centrioles are disengaged at the conclusion of mitosis, the daughter centrioles are nucleated in G1-S before they reach their full centriolar length, the daughter centrioles are lengthened in S and G2, and the centrosomes are separated (G2–M).

The circulatory system then transports those nutrients to their intended locations after the digestive system transfers any beneficial nutrients from meals to the blood.

Blood is pumped by the heart through an intricate web of blood vessels. For instance, your blood picks up nutrients your body received from your most recent meal as it travels through your digestive system. Oxygen inhaled by the lungs is also carried by your blood.
The heart relies on the digestive system
The digestive system is in charge of the ingestion, breakdown, absorption, and excretion of nutrients and minerals, whereas the circulatory system ensures that blood flows throughout the body and, in doing so, guarantees that each portion of the body receives the essentials for function. Both systems work together to provide nourishment to the many body sections.
When food is consumed, the transaction starts in the digestive system. In order to be absorbed into the bloodstream, this meal travels through the mouth, oesophagus, stomach, and small intestine, undergoing both chemical and physical digestion.
The mouth is where the ingested nutrients undergo chemical and physical digestion. The teeth and saliva break down the meal and produce a bolus, which is subsequently moved through peristalsis down the oesophagus and into the stomach. By churning the food and hydrolyzing components with the aid of stomach acids and enzymes, physical and chemical digestion take place once more in the stomach. Once the gastric juices and partially digested food are created in the pulpy acidic fluid that travels from the stomach to the small intestine, the nutrients move to the organ where the villi that line its inner wall absorb the nutrients and send them into the circulation.
Villi have capillary networks that correspond to the capillaries that surround the digestive organs. These capillaries take nutrients from the blood and transfer them to the liver through the hepatic portal system. The liver then processes the blood that is mineral-rich and releases various nutrients to serve other tissues of the body that require nourishing. This blood is transported by the circulatory system, so it may be transferred to the heart and circulated throughout the body, but it may also be distributed to other tissues and cells prior to the heart.
Specifically designed for carrying nutrients throughout the body, platelets are a type of blood cell that are in charge of carrying nutrients across the bloodstream and delivering them to the appropriate bodily tissues.
The digestive and circulatory systems are essential components of the body's systems and must cooperate to keep the body in a state of homeostasis and enable appropriate operation.

The typical American newborn weighs around 7.5 pounds and is around 20 inches in length. Infants normally lose about 5% of their body weight during the first few days of life as they get acclimated to feeding and removing waste. Most parents seem to miss this, but those who have tiny infants may find it worrying. However, this loss of weight is just momentary, as a quick period of growth follows.
