Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
Answer:
Crossing-over
Can light cause changes to metal
Answer:
yes it can cause changes to metal
Answer:
No.
Explanation:
The metal can't change because light is not a physical thing. the metal can change by getting warm and/or changing color, because different types of light can cause different changes to a material when they are absorbed.

In the previous activity, you chose an animal that interested you and listed three examples of innate behavior and three examples of learned behavior for that animal. Now research what, if any, courtship and mating rituals this animal has. Explain why you think it has or doesn’t have these behaviors.
Answer:
what grade
Explanation:
Courtship and mating rituals are diverse and can vary greatly among different animal species. They are typically involved in attracting mates, establishing pair bonds, and ensuring successful reproduction.
1. Courtship and Mating Rituals Exist: Many animal species have elaborate courtship and mating rituals. These behaviors can serve various purposes, such as displaying fitness and attractiveness to potential mates, establishing territory, or demonstrating parental abilities.
2. Absence of Courtship and Mating Rituals: Some animal species may not exhibit elaborate courtship or mating rituals. This can occur in species where mating opportunities are abundant or where the reproductive process is straightforward without the need for elaborate displays.
The presence or absence of courtship and mating rituals can depend on various factors, including ecological pressures, social structure, reproductive strategies, and evolutionary history of the species. Different species have evolved different strategies to maximize their reproductive success, and these strategies can manifest as complex courtship rituals or simpler methods of attracting mates.

Which process is shown in the plant cell below?
A= cell growth
B= cell reproduction
C= metamorphosis
D= photosynthesis
The given process shown in the image is cell reproduction. Cell reproduction takes place by mitosis and meiosis.
What is cell reproduction?Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis.
Meiosis, the second sort of cell division, makes sure that each generation of people has the same number of chromosomes.
Therefore, The given process shown in the image is cell reproduction. Cell reproduction takes place by mitosis and meiosis.

All cells share four common components:
a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment
cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found
DNA, the genetic material of the cell
ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.
What are the four main types of carbon based molecules.
Answer:
Lipids, proteins, nucleic acids, and carbohydrates.
Explanation:
These carbon-based molecules make up all organisms and living things. These 4 molecules are the four major types of carbon based molecules
Lipids, proteins, nucleic acids, and carbohydrates are the four main types of carbon based biomolecules.
What are biomolecules ?Biomolecules can be defined as the basic component of all living cell and it is the primary building blocks like Carbohydrates, Proteins, Fats, Nucleic Acids.
Carbohydrates or sugars are the primary energy source of body which are composed of polyhydroxy aldehydes or ketones formed by hydrolysis reaction; It can be monosaccharide, oligosaccharide and polysaccharides.
Proteins are the structural unit and it express character of a gene and synthesized by translation from RNA; It is a polymers of amino acids, can be up primary, secondary, tertiary and quaternary protein.
Nucleic acids are the house of all genetic material of the cell which are up two types namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Lipids are insoluble substance as it can not dissolve in water, soluble in only in non-polar solvents, include sterols, fat-soluble vitamins, mono-, di- or triglycerides, phospholipids, etc.

Answer: The answer would be B
Explanation: All plants and animals release at least some amount of co2 into the atmosphere during cellular respiration
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration can be determined based on the Carbon cycle model. So, the correct option is B.
What is Carbon cycle?The exchange and recycling of carbon in the Earth's biosphere, lithosphere, hydrosphere and atmosphere is known as the carbon cycle. All living things contain the element carbon, which is also an important component of many important compounds such as proteins, lipids, and carbohydrates.
Photosynthesis, respiration, combustion and weathering are just a few of the different processes that make up the carbon cycle. Plants use photosynthesis to take up atmospheric carbon dioxide and convert it into organic molecules. Plants and other organisms then use these molecules as a source of energy.
Therefore, the correct option is B.
