Answer:
What are centrioles and centrosome?
Within the cell, a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM. They also enable movement of other organelles within the cytoplasm

Answer:
a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM.
Centrioles are made up of short lengths of microtubules “arranged around a central cavity.” Each centriole is around 500 nm long and 200 nm in diameter. The function of centrioles in animal cells is to organize the PCM to aid in microtubule formation.

What is the main difference between mitosis and cytokinesis?
Answer:
Mitosis refers to a cell centre division into two, whereas cytokinesis refers to the further breakdown of the cell cytoplasm that forms two girl cells.
Specific cell organelles and cytoplasms are cytokinesis, whereas mitosis is only inherited through heritage.
Organelle division is not essentially equal during cytokinesis.

Enzymes are described as catalysts, which means that they __________. View Available Hint(s)for Part A increase the free energy of the reactants to make the reaction go faster provide activation energy for the reactions they facilitate can alter the free energy change (ΔG) for a chemical reaction are proteins increase the rate of a reaction without being consumed by the reaction
Answer:
Enzymes are proteins that are able to increase the rate of a reaction without being consumed by the reaction. They are also called natural catalysts.
Explanation:
Enzymes increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed.

Do you think one gene controls human hair color? Explain your answer.
Do you think one gene controls human hair color?
No, this is false. Not only one gene is responsible for the colour of your hair, at least 2 gene pairs control human hair colour. Therefore, this is wrong since each parent contributes multiple hair-colour genes .
Hope this helped you, have a good day bro cya)
Answer:
There are many different phenotypes for hair color among humans. Therefore, multiple genes control hair color.

How is coal and petroleum formed
Answer:
Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.

The property that is shared by the cells of all living things the cells contain DNA composed of adenine, thymine, guanine, and cytosine. The correct option is A.
What are living things?Living things are those things that are alive, The main property of a living thing can distinguish them from non-living things. These properties are growth and reproduction.
The living cells are those cells that made all the living matter. The living cell is composed of macromolecules. The cell is composed of DNA and different cell organelles.
DNA is present in every living organism. It determines the genetic difference of every organism. It is the same in every cell.
Thus, the correct option is A. The cells contain DNA composed of adenine, thymine, guanine, and cytosine.

Hox genes are regulatory genes in multicellular animals that code for transcription factors that determine the basic body plan in a developing embryo. They act as switches that turn other genes on and off. Scientists have found that a mutation in a fruit fly hox
gene produces flies with legs instead of antennae sticking out of their heads. Another hox gene mutation results in fruit flies with
two pairs of wings instead of one pair. Hox genes affect body plans by controlling the expression of many other genes
Many multicellular animals have the same hox genes. Which statement is evidence for this claim?
(1 point)
O There is a wide variety of body plans in complex animals.
o The body plans of complex animals are very similar to one another
The body plans of complex animals change over generations
The body plans of complex animals typically have a large number of mutations.
Hi! Welcome to Brainly! Thanks for asking a question!
So, based on the options provided in the question above, the correct option would be 'the body plans of complex animals are very similar to one another' or in other words Option B or 2.
Hope this helped! Happy holidays!
The correct option is The body plans of complex animals change over generations.
What are hox genes?
Hox genes are important regulators of how the animal body plan is organized. They contain transcription factors that when combined can give instructions to cells at various body levels on their potential morphological contributions.
In addition to its historical role in the anterior-to-posterior (AP) axis, HOX proteins also help to organize secondary axes and a number of different organs and tissues. Hox genes are grouped together in the genomes of many species that exhibit bilateral symmetry.
Because the sequence of genes in cis inside the cluster corresponds to the order of their expression domains along the various axes, this specific genomic architecture has functional significance.
Therefore, The correct option is The body plans of complex animals change over generations.
