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 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.

The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second.

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.

Which of these is not an example your body maintaining homeostasis?

A-When exercising, your body releases more energy to your muscles.

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!

A student is conducting an experiment with biochemical reactions and notices that at high temperatures, the reaction rate decreases significantly.

Which statement best explains the decrease in reaction rate?


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.

HydrolysesOxidoreductaseLyasesTransferaseLigasesIsomerase

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.

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

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.
