Why scientist believe that virus are not living organisms?

Scientists consider viruses non-living because they lack essential features of living organisms, such as the ability to replicate on their own or carry out metabolic processes. Viruses can only replicate by infecting host cells and hijacking their machinery. Additionally, viruses do not display characteristics of cellular life, like growth and energy production.

Why daughter is similar to dad?

If you mean physical traits like appearance, these are passed genetically to children by both mother and father. Some genetic traits are dominant and some are recessive. If the father has dominant traits, such as brown eyes, while the mother has recessive traits, like blue eyes, it is more likely that brown eyes will be passed to either a son or daughter.

If you decided to have a child one day and are given the opportunity to select for special traits would you do so explain?

Well, honey, if I were in the market for a mini-me, I'd just take whatever the universe throws at me. I don't need to play genetic bingo to create a masterpiece. Kids are like a box of chocolates, you never know what you're gonna get, and that's the fun of it.

What is the utility of tissues in multi-cellular organisms?

1>fomation of tissue has brought about division of labour in multicellular organism

2>tissue become organised to from organs and organs into organ system

3>workhood of individual cell has decreased

4>due to improved organisationand higher efficiency multicellular organism have higher survials

Is DNA used to identify genetic disorders?

Yes, DNA is commonly used to identify genetic disorders. By analyzing an individual's DNA, genetic mutations or variations that are associated with specific disorders can be identified. This information can help with diagnosing, predicting risk, and providing personalized treatment options for individuals with genetic disorders.

Which molecules make up the horizontal rungs of a DNA ladder?

The horizontal rungs of a DNA ladder are made up of nitrogenous bases, specifically adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up in a complementary manner (A with T, and G with C) to form the base pairs in the DNA double helix.

If DNA is ladder like which two molecules of a nucleotide form the sides or upright portion of the ladder?

Oh, dude, it's like the nucleotides are the building blocks of DNA, right? So, the sides of the DNA ladder are made up of sugar and phosphate molecules bonded together. It's like the backbone of the whole DNA structure, holding it all together.

How can interlocking wall blocks be used to create a sturdy and durable structure?

Interlocking wall blocks can be used to create a sturdy and durable structure by fitting together tightly, creating a strong bond that can withstand pressure and weight. The interlocking design helps distribute the load evenly, making the structure more stable and less prone to shifting or collapsing. Additionally, the blocks can be reinforced with concrete or rebar for added strength and durability.

How can I safely transport a ladder up and down stairs?

To safely transport a ladder up and down stairs, make sure the ladder is the right size for the stairs and is in good condition. Use a ladder stabilizer or have a helper assist you. Carry the ladder parallel to the ground and use proper lifting techniques. Take your time and be cautious to avoid accidents.

How can I safely secure an extension ladder with a rope?

To safely secure an extension ladder with a rope, follow these steps: First, extend the ladder to the desired height and lean it against a stable surface. Then, tie a rope around the top rung of the ladder and secure it to a sturdy anchor point, such as a tree or a heavy object. Make sure the rope is tight and the ladder is stable before climbing.

How can I prevent the f2 error on my oven?

To prevent the F2 error on your oven, you should check and clean the oven temperature sensor, ensure proper ventilation around the oven, and avoid overloading the oven with heavy cookware.

How can I learn how to build a ladder?

You can learn how to build a ladder by researching online tutorials, watching instructional videos, or taking a woodworking class. Practice using the right tools and materials to construct a safe and sturdy ladder.

What best describes covering and lining epithelium?

Covering and lining epithelium is a type of tissue that forms the outer covering of the body and lines organs and cavities. It is made up of closely packed cells that protect underlying tissues and organs, as well as aiding in absorption and secretion. These epithelial cells have specialized structures that allow them to perform their specific functions.

In which form is the DNA present in a cell when the cell is not dividing?

During the interphase stage of the cell cycle when the cell is not dividing, DNA is present in the form of chromatin. Chromatin is a complex of DNA and proteins, mainly histones, that condenses to form chromosomes during cell division. In its chromatin form, DNA is loosely packed and allows for gene expression and various cellular processes to occur.

What is the difference between a chemical formula and chemical equation?

A chemical formula is just one molecule. For example, the chemical formula for water is H2O. The chemical formula for ammonia is NH3

A chemical equation contains reactants and products, which are molecules or groups of molecules. For example, what is the chemical equation for the formation of water.

2H2 + O2 ---> 2H2O

Is nuru gel safe if swallowed?

Well, honey, let me break it down for you. Nuru gel is typically made from natural ingredients, so it's probably not going to kill you if you accidentally swallow a little bit. However, it's not meant to be ingested, so I wouldn't recommend making a habit out of it. Just stick to using it for its intended purposes and keep it out of your mouth.

When a chromosome has been duplicated it consists of two identical pieces attached together called?

A chromosome is a long, highly coiled strand of DNA. When the cell is undergoing replication, the DNA strand will replicate to form two identical copies, one copy goes to each daughter cell.

However, a human cell consists of 23 paired homologus chromosomes to give 46 chromosomes in total.

What did the experiments of griffith Avery and Hershey and chase show?

The first major experiment that led the discovery of DNA as the genetic material was performed by Griffith and Avery. They studied 2 strains of bacteria "Streptococcus Pneumonia, which causes pneumonia. They found that one strain could be transformed into other forms of bacteria and germs.

What are examples of harmless mutations?

A neutral mutation has no benefit to the organism. It is neither helpful or harmful. One of the best examples are ear lobes or even ear shapes in general. Some people have attached ear lobes, some do not. Another is finger length. Most humans have similar finger lengths but there is a variation in these. One doesn't seem to give a benefit to the owner or harm that same owner.

What are the two faults which exist in a simple cell?

The two main faults that can occur in a simple cell are an open circuit fault, which disrupts the flow of current by breaking the circuit path, and a short circuit fault, which causes a direct path between the positive and negative terminals, leading to excessive current flow. Both faults can impair the cell's ability to function properly.

How many cells does a giraffe have?

they have to about 1,000,000 cells in there body

Why do all babies in a mothers womb start off as a girl?

All babies do not start off as a girl in the mother's womb.

Here's why:

Women only produce X chromosomes. Men produce both X and Y chromosomes. XX = female and XY = male. When a woman's egg (X) is fertilized by a man's Y sperm a boy baby is conceived. When a woman's egg (X) is fertilized by a man's X sperm a girl baby is conceived.

So the man makes a son or a daughter. The woman is unable to determine the gender of the baby. During conception there is a 50% chance of creating a boy and a 50% chance of creating a girl but either way it all depends on whether a Y sperm gets to the egg first to fertilize it OR an X sperm reaches the egg first.

Gender is complete at the moment of fertilization (conception) and then the baby (whether male or female) continues to grow and develop in the mother's uterus (womb).

-----

^That's not fully correct

All babies do have a set gender but they do all start off with female sex organs. This is because the male organs form from chemical stimulation of the female organs. We don't know why this is.

And in cases of pregnancies at an older age, there is more chance of chromosomal abnormalities, which means the mother could be the one to create the male baby (and not the dad like normal pregnancies).

What color will the baby be with a black mum and white dad?

Your Baby will most likely be born a pasty sort of white and then will be totally cute a few days later! Congrats!

Actually, if you are wanting an honest true answer, your baby can range from rather light white to a dark black. It just depends what genes get passed to the child. Whatever color the baby is I'm sure it will be beautiful!
