Answer:
A gene is a section of a double-stranded molecule known as DNA. This molecule is found within the nucleus of the cell, contained in threadlike structures called chromatin. The two strands form a double helix linked by a series of paired bases. The base adenine is always linked to thymine and the base cytosine is always linked to guanine.

Form a hypothesis that explains your choice. You will be able to revise your hypothesis after performing experiments.
Hello. You have not informed the experiments to which the question refers, which makes it impossible for hypotheses to be formed. However, I will try to help you in the best possible way.
A hypothesis is an assumption, that is, it is a statement that the researcher believes to be true in relation to the research results, which can be proven or denied when the experiment is finished and the conclusions are established. Therefore, you must make assumptions about the results of the experiment, based on your primary visualization of them.

answer:
this is the cell theory, which was proposed by Theodor Schwann in 1839
explanation:
in biology, cell theory is the historic scientific theory it states that living organisms are made up of cells, they are the basic structural/organizational unit of all organisms and all cells come from pre-existing cells.Answer:
This is called cell theory. This was first proposed by Theodor Schwann and became an important part of science today.
The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.

A murder occurs in a nursing home during a night full of thunderstorms and pouring rain. The victim is discovered lying on the plush carpet of the rec room, bleeding from a wound to the head. The staff assures investigators that there must have been a break-in because no one who lived or worked at the facility would do something like that. Considering the Principles of Trace Evidence, what would investigators be looking for to prove that someone entered from outside the facility?
Muddy or wet footprints in the carpet
The discovery of a murder weapon
Letters to the victim from a sick relative
Blood spatter from the victim's head wound

A
Explanation:
he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigmented phenotype. However, feeding silver salts to larvae results in adult flies that phenocopy the yellow phenotype. You are conducting epistasis experiments in fruit flies to understand the genetics of pigmentation. A rival research lab sends you a vial of yellow-bodied flies for your experiments. How can you tell whether these flies are mutants instead of phenocopies
Answer:
We could feed them with another type of food free of silver salts.
Explanation:
When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.
If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

Some minerals are evenly distributed around the planet, while other minerals are quite rare. Why are some minerals so rare and unevenly distributed?
A. Certain minerals form only under high heat and pressure that develop near volcanoes.
B. Certain minerals form only in Earth's crust, so they are difficult to locate.
C. Certain minerals form only in specific climates, and not all climates, are the same around the world.
D. Certain minerals form only in the extreme heat found at the bottom of lakes and rivers.
Please answer with an explanation THAT ISNT a browser answer you just copied pls
Answer:
A.
Explanation:
certain minerals form only under high heat and oressure that develop near volcano. That is why minerals vary among areas.
The option (C) is correct. Certain minerals form only in specific climates, and not all climates, are the same around the world.
What are minerals?A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.
Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.
