Explanation:
it occurs during meiosis. Its the exchange of chromosome pieces between the non-sister chromatids during the production of gametes.
Answer:
Crossing-Over is a DNA segment on each chromosome section may code for eye color, although one chromosome may code for brown eyes and the other for blue eyes. Crossing over occurs most often between different alleles coding for the same gene.

What does the water molecule do in the Lithosphere during the Water Cycle.
Answer:It's a process that happens on a molecular level when the molecules of water are really energized and rise into the air.
Explanation:

Water moves from the ground or oceans into the atmosphere through a process called evaporation.
10. What is the structure of chromatin and how does it affect gene regulation?
Answer:
Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Chromatin structure plays a key role in regulating gene expression by allowing DNA accessibility to transcriptional machinery and transcription factors.

Explanation:
Which one of the following requires the highest degree of metamorphism?
a. gneiss
b. shale
c. slate
d. schist
Answer: a. gneiss
Explanation:
Metamorphism can be defined as the synthesis or formation of minerals or rocks from the pre-existing rocks. This involves various physical and chemical processes. The physical processes include the application of heat and pressure. The chemical processes include the oxidation, reduction and other chemical reactions occurring within the rock. Gneiss is one of the highest grade of metamorphic rock. As it exhibit the coarsest grain size. Quartz, mica, and feldspar are the examples of gneiss.

Explain, using a named example, why many sex-linked diseases occur more frequently in men than women
Answer:
Because men have Y-chromosomes.
Explanation:
In women, the final chromosome is XX, but in men, it is XY. Because this Y gene is different, genetic disorders are typically linked to this chromosome. A mutation in the X chromosome is equally prevalent in the population, meaning that the Y chromosome makes a male more likely to have a disease because they are more likely to have a genetic disorder, due to having both an X and Y chromosome.

These devices generally use some sort of transmitted energy such as radar waves or infrared beams to detect vehicles passing over the roadway.
Explanation:
how does an organism use the information in dna
Explanation:
DNA's instructions are used to make proteins in a two step process.
1st- Enzynes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid (mRNA).
2nd- Information contained in the mRNA molecule is translated into amino acids, which are the building blocks of proteins.
plz help!!A biologist claims that during lake succession, fish such as trout are slowly replaced by fish such as bluegills. How must these fish be different for this claim to be TRUE?
A. Bluegills must be larger than trout.
B. Bluegills must require less oxygen than trout.
C. Bluegills must require less nitrogen than trout.
D. Bluegills must have a greater population size.
Answer:
D. Bluegills must have a greater population size.
Explanation:
Hope this helps!
Trout fish are slowly replaced by Bluegills fish because Bluegills must have a greater population size.
What is Lake Succession?
Lake succession is a term used to describe the process of continuous aging in a lake in terms of its physical and biological properties.
As the population size of Trout fish is lesser, and the process of succession happens, it is replaced by the species that have greater population size.
Therefore, Trout fish are slowly replaced by Bluegills fish because Bluegills must have a greater population size.

Transpiration is the process of water movement through a plant and its evaporation from plant parts, such as the leaves, stems and flowers. Water is necessary for plants, but only a small amount of water is taken up by the roots and is used for growth. Why must plants transpire most of water if they only need a small amount of it for development? pls answer the question fast.
Answer:
Plants absorb water in a large amount because water is the only medium which is present in a plant for the transportation of minerals. So, the plant absorbs a lot of water even if it is lose by transpiration.

The study of the connection of the roles of different animal systems is called
The connection between different animal systems is a part of ecology study, in which every animal plays a different role to balance the ecosystem.
What is ecology?In the ecology study of the interaction between organisms and their abiotic environment, different animal systems play different roles.
In a particular ecosystem, every organism is dependent on others to maintain a balanced life which affects its surrounding environment.
An animal system is a group of animals in a particular habitat that describe a particular species interaction in which an organism interacts with its surrounding environment.
Therefore ecology is the study of connections between different animal systems.
