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.

The atoms and molecules that make up substances are always in motion. What happens when heat or thermal energy is added to a substance?
the particles move faster
the particle movement doesn't change
the particles move slower
the particles stop moving
Answer:
the particles move faster
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Answer:
the particles move faster
Explanation:
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.

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.

a. Evolution is an example of the major mechanism by which natural selection occurs.
b. Natural selection is an example of the major mechanism by which evolution occurs
c. Natural selection occurs separately from any involvement with the process of evolution.
d. Evolution occurs separately from any involvement with the process of natural selection.
Answer:
B
Explanation:
i got B because in the question it says
Natural selection is an example of the major mechanism by which evolution occurs. So, the correct option is (B).
What is an Evolution?Evolution is defined as the change in the genetic characteristics of a biological population over successive generations, where these characteristics are expressions of genes, which are passed from parent to offspring during reproduction.
Evolution in organisms occurs through changes in genetic properties such as inherited characteristics of an organism. In humans, for instance, eye color is an inherited trait and a person can inherit the "brown-eye trait" from either of their parents.
It involves changes in the heritable properties of a population of organisms as successive generations replace each other which is a population of organisms that evolves, not individual organisms. Example of Evolution is Natural selection.
Thus, Natural selection is an example of the major mechanism by which evolution occurs. So, the correct option is (B).

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.

include those that occur in a burning bonfire and a wind turbine.
• Do research to find out about an energy transformation that affects your daily life.
• Find out what the starting types of energy are and what the ending types of energy are.
• Decide how many steps in the process your poster will show.
• Create bar graphs or pie charts to show the relationship between the different types of
energy at different steps in the transformation process.

Energy can only be changed from one form to another; it cannot be created or destroyed. The law of energy conversion or the law of energy conservation are other names for this.
Explain about the Energy transformation?Energy transformation is the process by which plants transform solar light energy into a more useful form using photosynthesis. Energy transformations are also used by people. The body transforms the stored energy in meals into a form that may be utilised by the body. It is known as cellular respiration.
The cell transforms this chemical energy into a number of other forms over the course of several stages with minimal heat loss, including the energy of the chemical bonds in its own substance's molecules, the mechanical energy of muscle contraction, and the electrical energy of nerve impulses.

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.

Term: Chromosphere. Convective zone. Core. Radiative zon.
Definition: A.) Layer of the sun where energy is transferred by thermal conduction.
B.) The central and hottest section of the sun.
C.) Layer of the sun where energy is transferred by convection.
D.) Layer of the sun that is known for its red color and can only be seen during eclipses.
Answer: The answer is the layer of the sun that radiates energy outwards from the sun core
Explanation: the reason why that is becuase the convection zone is a layers which is unstable to convection. And energy is primarily or partially transported by convection
The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core. The layer of the sun where energy is transferred by convection is the convective zone and the layer of the sun known for its red colour that can only be seen during eclipses is the chromosphere.
What is the Sun?It is the central star of our solar system around which the planets and other planetary bodies revolve. Ninety-nine per cent of the mass of the entire solar system is constituted by the sun.
The sun produces a tremendous amount of energy. A part of this energy reaches the earth. The perfect distance of the earth from the sun ensures that this energy supports life on earth.
The sun is considered to be a 'dwarf' star among the other stars studied and observed in the observable universe. The sun has been formed from the material which had been processed inside of a supernova and is present in the outer regions of our milky way galaxy. The sun is made of several layers and each has its own role.
Therefore, The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core. The layer of the sun where energy is transferred by convection is the convective zone and the layer of the sun known for its red colour that can only be seen during eclipses is the chromosphere.
