Chromosomes are composed of two types of biomolecules. One of the biomolecules in chromosomes is called DNA, which functions as the genetic code. The other biomolecules in chromosomes are called histones, which bind the DNA tightly for cell division. Genes in DNA have the code for making histones. Based on the information above, which types of biomolecules are in chromosomes?
F Carbohydrates and lipids
G Proteins and nucleic acids
H Proteins and carbohydrates
J Nucleic acids and carbohydrates cationTM Inc
Answer:
proteins and nucleic acids
histones are proteins and DNA is made up of nucleic acids (these are the macromolecules made up of nucleotides)
Explanation:
Chromosomes are thread like structure found in nucleus of cells. It contains several biomolecules in it. DNA is nucleic acid whereas histones are protein. Hence, option “ G” is correct.
What are biomolecules?Molecules that are produced by living organisms are called biomolecules.
Example of biomolecules are Carbohydrates, Proteins, Nucleic acids and Lipids.
Carbohydrates are sugar molecules such as Glucose, Galactose Maltose, Fructose, Sucrose, Lactose, and Starch.Protein structures are of four types primary, secondary, tertiary, and quaternary structure. Histone is a kind of a protein. Nucleic acids include DNA and RNA.Biomolecules present in chromosomes are nucleic acid (DNA and RNA) and Histone protein. Hence option “G” is correct.

Question 8(Multiple Choice Worth 1 points) (06.04 MC) Which statement best explains how arteries and veins help maintain homeostasis? The carbon dioxide exhaled by the lungs is carried by the veins and arteries to the different parts of the body. Arteries carry oxygen-rich blood to the different parts of the body, and veins carry carbon dioxide-rich blood to the heart. Veins carry oxygen-rich blood to the different parts of the body, and arteries carry carbon dioxide-rich blood to the heart. The oxygen inhaled during respiration is carried around the body through blood by veins and arteries to maintain homeostasis.
Answer:
Explanation:
Arteries carry oxygen-rich blood to the different parts of the body, and veins carry carbon dioxide-rich blood to the heart. The oxygen inhaled during respiration is carried around the body through blood by veins and arteries to maintain homeostasis.

What are gas giants?
A gas giant is a giant planet which is composed mainly of hydrogen and helium gases. Gas giants are also known as failed stars because they contain the same basic elements which are present in the stars. Jupiter and Saturn are the gas giants of the Solar System. The gas giants can also be called as giant planets.
The four gas giants in the solar system are Neptune, Uranus, Saturn, and Jupiter.

Explain homeostasis and why it’s important to the body
Answer:
Homeostasis regulates your body. When you are too hot, your body produces sweat to cool you down. When you're cold, you muscles shiver to generate warmth. When you have high glucose levels in your blood, your pancreas excretes insulin, and when blood glucose is too low, then it excretes glycogen. Homeostasis basically keeps your body from losing control and it helps you survive.

Answer:
MOST FLOWERS ARE STANDING STRAIGHT UP. FLOWERS ARE MOST LIKLEY TO REPRDUCE THROUGH THE WIND. SINCE THE FLOWER IS STANDING STRAIGHT UP IT WILL CATCH MORE.
Explanation:
im d u m b and left caps lock on.
The the structures in flowers increase their odds for reproduction and most flower are standing straight up and flower are most likely to reproduce through the wind. Since the flower is standing the straight up it will catch more.
What is pollination?The term pollination has been defined as the act of the exchanging the pollen grain from the anther which is male part of the flower to the stigma female part of the flower. This is the main objective of each and every living organisms.
Reproduction has been defined as the process carried out by the living organisms and during the process of the reproduction the living organisms produces their own young ones and feed them. Reproduction has been the supreme quality of living things.
There has been two types of the reproduction and these are the sexual and asexual reproduction. The process of the reproduction in which two parents are involved has been said to be sexual mode of the reproduction and the process of reproduction in which only the single parent has been involved is known as the asexual mode of the reproduction. The example of the asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, The the structures in flowers increase their odds for reproduction and most flower are standing straight up and flower are most likely to reproduce through the wind. Since the flower is standing the straight up it will catch more.

What is an example of how anatomical homologies (similar bone structure) are used to
show evidence of common ancestry among groups of organisms?
(1) Use complete sentences to explain the advantage of using binomial nomenclature in the system of classification. Also explain what kind of information you can get about the organism from its scientific name.
(2) The diagram below shows the branching tree diagram for humans. The text box below it shows the set of derived shared characteristics for the branching tree.
A slanting, horizontal line is shown. On the extreme left, there is a label that says Common Ancestor. Along the slanting, horizontal line there are five dots labeled from left to right as 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right, Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. From the text box, select a shared derived characteristic that frogs and pigeons have. Explain why you think frogs and pigeons share this characteristic.
Answer:
The advantage of using a binormal nomenclature in the system of classification is it formally names animals of a species of living things by giving a two-part name which either is based on Latin or other languages. One Part is used to classify the genus and the second part of the specific name. An example of this would be ( for humans ).

Availability of waterTemperatureNatural DisasterWhat is Natural Selection?
Natural selection is a set of characters that deal with the most favorable variations that are promoted by nature.
As predators, the height of legs, fur, the color of the body, size of the body, and size of the beak is not related with environmental changes. It can also be said that these characteristics lead to natural selection depending on the conditions, such characteristics are not linked with environmental changes directly.
Therefore, the three examples of environmental changes that can influence natural selection are the availability of water, temperature, and natural disasters.

Temperature can affect density in certain ways. If the temperature decreases, what effect can that have on the density of a substance?
Liquid water at 25 deg is so rapidly breaking bonds between H2O units and reforming them that extra water molecules get trapped inside the water lattice. This is the reason why liquid water is more dense than solid water.
The bonds in water break more slowly as temperature decreases and the structure tend to trap fewer extra water molecules. At low temperature, more of the water has the same lattice as ice.
Wikipedia, Water Density
It is possible to have liquid water at temperatures well below 0 deg C. Molecules in this supercooled water are free to move. Bonds are made and broken. The long range structure is not perfect but the short range structure of supercooled water is very much like ice. Adding a crystal to supercooled water causes instantaneous ice formation.
