Hi! Thanks for asking your question here on Brainly!

Answer:

Chemicals in the body of a living organism is one of the many factors determined in gene expression.

Explanation:

The presence of drugs and/or chemicals in a living organism's environment, this can also influence gene expression in the organism.

Hope this helps :D Happy Holidays!

Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous chemical substances, other environmental effects, and age.

What are the factors that affect gene expression?

The level of transcription is where the majority of control over gene expression is exerted, and this is mostly due to the fact that proteins bind to certain locations on DNA.

It is possible for environmental elements such as nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens to have an effect on which of an animal's genes are expressed, which in turn has an effect on the animal's phenotype.

Define negative feedback in biology

Answers

Answer:

A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. In this way, a negative feedback loop brings a system closer to a target of stability or homeostasis

Explanation:

Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances

How many seconds would it take DNA polymerase to replicate one set of human chromosomes (6,000,000,000 bytes long)

Answers

The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second. At that speed of DNA replication, it would take the cell over a month to copy a chromosome.

What is chromosome ?

A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.

A-When exercising, your body releases more energy to your muscles.
B-On a hot summer day, you produce sweat.
C-When you get a virus, your body systems react to fight it.
D-When you see a piece of cake, your mouth waters.

Answers

Answer:

D. When you see a piece of cake, your mouth waters.

That’s between A & B because maintaining homeostasis is dealing with temperature and how your body reacts to it so I’ll most likely say B because that’s your body reacting on a hot summer day which is homeostasis so you sweat because you hot and also I’m also talking about maintaining homeostasis in school!

Although the water cycle can be divided and subdivided into various processes, we can simplify it into four simple steps:

EvaporationCondensationPrecipitation Collection

The one saw in the biome and one of the most essential parts of the cycle is condensation. It is the collection of water molecules into a single group that, when dense enough, fall back onto the earth as rainfall. In nature these take the form of clouds, meanwhile, in the biome, they appear as water on the sides of the container.

what is true of a fossil that is classified as a transitional form?

Answers

Given our understanding of the situation, we can confirm that a fossil classified as a transitional form, will show characteristics both of its ancestors and of the descendants that derived from it.

Transitional fossils are just that, fossilized remains of a transitional phase of evolution. What this means is that as species evolve, there will always be a point in time where a species is at a halfway point in between the species from which it comes, and the species that it will become.

These fossils, due to being a halfway point, will have characteristics that belong to their ancestors, but also characteristics that belong to their descendants, which is only logical considering that evolution is a process that spans many generations, not something instant.

The bonds of the substrate were breaking.

The enzyme bonded with the substrate.

The enzyme denatured and changed shape.

The activation energy was increasing.

Answers

Answer:

The enzyme denatured and changed shape

Explanation:

Enzymes are proteins, which can only function properly within a certain range of temperatures- when things get too hot, proteins undergo a structural change and are considered to be 'denatured'. This means that enzymes will not be able to function properly under those high temperatures, because the substrate bonding site would no longer be the right shape for said substrate.

The statement best explains the decrease in reaction rate is the enzyme denatured and changed shape. Thus option 3 is correct.

What are enzymes?

Enzymes are defined as a material that functions as a catalyst in living things, controlling the pace at which chemical processes take place without changing the substance itself.

There are six types of enzymes.

The functions of enzymes are:

In human bodies, enzymes facilitate metabolic reactions. From breathing to digestion, they support.Health issues might result from having a too amount or too little of a certain enzyme. To help their bodies function as they should, certain persons with chronic diseases may need to take enzyme supplements.
