Answer:
Uranus, like Earth, has four seasons. ... For starters, the length of Uranus' seasons are different from ours. It takes Earth 365 days to orbit around the sun, but it takes Uranus 84 Earth-years, more or less. So Uranus' year is 84 Earth-years along, and each season on Uranus lasts 21 earthly years.

3. What does the salt do?
4. What was the purpose of cooling the mixture?
5. What does the cold ethanol do?
6. Why can't we use room temperature ethanol?
7. Why are strawberries classified as octoploids?
Answer:
3.You might think this should mean you need to cut out salt completely, but salt is actually an important nutrient for the human body. Your body uses salt to balance fluids in the blood and maintain healthy blood pressure, and it is also essential for nerve and muscle function.
4.Cooling the mixture is to prevent the DNA from being degraded by the heating.
5.The ethanol pulls water from the DNA molecule so that it then collapses in on itself and precipitates. The DNA will become visible as white mucous strands that can be spooled with the wooden applicator stick.
6.The colder the ethanol is the greater the amount of DNA that is precipitated. (You could try having some of the students use room temperature ethanol and see if the amount of DNA they can spool is the same or less than that for the groups using the ice-cold ethanol.
7.The reason is every strawberry seed contains different genetic material, the product of a myriad of potential gene combinations. Because the genetics of strawberries are so diverse (humans are diploid, strawberries are octoploid)

What is the process by which new oceanic crust is?
Explanation:
Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth's mantle. Seafloor spreading creates new crust.

Which of the following is true regarding the process shown below?
A. This process is cloning and involves the production of RNA from protein molecules.
B. This process is replication and involves the production of DNA from RNA.
C. This process is translation and involves the production of proteins from RNA.
D. This process is transcription and involves the production of proteins from DNA.
Answer:
C. This process is translation and involves the production of proteins from RNA.
Explanation:
- In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids.
Answer:
Translation

Species can change over time and adapt to their environment.
A. True
B. False
Answer:
True
Explanation:
This statement is true. A species can always change over time and adapt to their environment.
What are species?A species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. It is a class of plants or animals whose members have the same main characteristics and are able to breed with each other.
Moreover, it is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behavior or ecological niche.
Hence, species can change over time and adapt the conditions according to their environment.

Desiccation resistant spores, protective and complex reproductive organs, and embryos nourished by parental tissues enable land plants to ______.
Answer:
to adapt to dryland conditions
Explanation:
The main groups of land plants are vascular plants and they have developed diverse adaptations to survive on land, especially in climatic zones where drought and high temperatures are common. Some of the most important plant adaptations to land ecosystems include, among others, the development of a cuticle to prevent water loss, stomata capable of regulating water evaporation, desiccation-resistant spores coated in sporopollenium polymer, etc. Moreover, in seed plants, which are considered to be the most evolved vascular plants, the endosperm tissue produced inside the seeds is nourished by the parent sporophyte during the first stages of plant development.
Desiccation resistant spores, protective and complex
reproductive organs, and embryos nourished by parental
tissues enable land plants to adapt to dry conditions.
What is Dessication?
This is the process in which a substance dries up as a result of
loss of moisture.
In plants, resistant spores, protective and complex
reproductive organs, and embryos nourished by parental
tissues which helps to prevent desiccation and ensure that the

Differentiate between cell mass and cell number
Answer:
Measurement (Count) of Cell Numbers:
1. Breed Method:
A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.
Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.
Answer:
cell mass: The total mass of all the cellular elements in the body which constitute all the metabolically active tissue of the body
Cell number: The sequence of numbers or characters, that when dialed, connects to a particular cellular telephone

give two reasons that a particular molecule may be unable to cross the plasma membrane
Answer:
The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.

How can you use genetics to study human inheritance?
Answer:
by analyzing how genes influence the development of phenotypic traits, i.e., by determining the association between phenotypic traits and changes in DNA sequence
Explanation:
Genetics is a discipline that studies how genetic variation, i.e., the variation in the Deoxiriibunicleinc acid (DNA) molecule, is associated with the transmission of heredity, and how the environment influences this process. The DNA is a molecule that carries the instructions to perform all metabolic functions (eg., reproduction, development, growth, etc). Thus, advancements in genetics enabled us to decipher how phenotypic traits pass from parents/ancestors to their offspring/descendence. Genes are segments of DNA that carry the information (genetic information) to determine each phenotypic trait. During reproduction, genes are passed from one generation to the next, thereby transmitting this information across generations.
