Explanation:
Which base is found only in DNA?
O adenine
O guanine
O cytosine
othymine
Thymine is the base that is found only in DNA. Adenine, guanine, and cytosine are also present in both DNA and RNA, but thymine is exclusive to DNA. In RNA, uracil replaces thymine.
What are nucleotide bases?Nucleotide bases are the building blocks of DNA and RNA, the genetic material in all living organisms. There are four nucleotide bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, uracil (U) replaces thymine. These bases pair with each other to form the "rungs" of the DNA ladder, with A always pairing with T (or U in RNA) and C always pairing with G.
The sequence of nucleotide bases in DNA determines the genetic information carried by an organism. DNA replication, the process of copying DNA before cell division, relies on the complementary base pairing of nucleotide bases to ensure that each new strand of DNA has the same sequence as the original.
Mutations, or changes, in the sequence of nucleotide bases can occur naturally or as a result of external factors such as radiation or chemical exposure. These mutations can lead to genetic variations and may have consequences for the organism.

0.25 recessive alleles are present in your overall population.
What are recessive alleles?In terms of genetics, the term "recessive" describes the connection between an observed trait and the two inherited forms of a gene associated with that feature.
Each gene has two alleles that an individual inherits from each parent. When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest. When there is only one copy of an allele, it has no effect at all.
This is in contrast to a dominant trait, which can only be expressed when one of the two alleles is present.
Therefore, 0.25 recessive alleles are present in your overall population.

Weight measures the _____ of gravity pulling in an object.
Weight measures the downward force of gravity pulling in an object.
Explanation:Weight measures the downward force of gravity that is generated on an object. The weight of an object changes depending on its location. For example, an object located on Earth weighs heavier than when it is on the moon because the Earth exhibits a stronger gravitational force.

Why is the birth of modern science (c.1500-1700) important to how we understand knowledge and disciplinary divisions today
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The birth of modern science (c.1500-1700) was important to how we understand the knowledge and disciplinary divisions today because the scientific method was established to get proper validation to the things in nature that in the past were attributed only to dive concepts expressed by the Church.
That old fashion way of thinking, validated by the church during the dark ages of Medieval Times, only created fear and fostered ignorance in people.
The advent of modern science changed this thing, basing its theories and answers on proper research that could be proven. That is how the human mind expanded and grew. No more myths and distorted religious beliefs that were so wrong.
Changes to _______ can be ascribed to glacial melting. a. Earth’s surface b. CO2 levels c. coral reefs d. water pollution
Answer:
a. Earth’s surface
Explanation:
The glacial process is a geomorphological process caused by the action of ice, snow, and frost.
When the water flows away from the glacier melting of the sea, it goes to the ocean, so the amount of water in the ocean provokes the changes on the coasts. This is happening slowly and, in the end, we are starting to see changes in the Earth's surface
Answer:
Earth’s surface

In the compound microscope, If you see bacteria move to the right,
this bacteria on the slide, really move to:
O a. Left
b. Downward
on
c. Upward
O d. Right
Clear my choice
Answer:
a
Explanation:
In a compound microscope, if a bacterium moves to the right, the bacterium on the slide, in reality, moved to the left.
This is because the optical system of the compound microscope is designed in such a way that the lenses change the orientation of the image of objects when viewed.
The system of two lenses - the objective and the eyepiece - produce inverted images of objects on slides. Hence, when an object on the slide under the compound microscope moves to the right, it is seen as moving to the left to the viewer and when it moves up, it is seen as moving down by the viewer.
The correct option is, therefore, a.

What does the forward arrow in a chemical equation mean? (1 point)
O The reaction is reversible.
O The reaction proceeds slowly.
O The reaction proceeds quickly.
O The reaction yields something.
Answer:
D.) The reaction yields something.
Explanation:
A.) is incorrect. A forward arrow means a reaction only occurs in the forward direction (reactants to products). If the reaction were reversible, there would be double arrows, one pointed forward and another pointed backwards. This would symbolize that the reaction can take place in both directions.
B.) and C.) are incorrect. The direction of the arrow in a reaction gives no information regarding the rate of the reaction.
D.) is correct. In the case of chemical reactions, to yield something means to create something. A forward arrow indicates that reactants are undergoing a chemical reaction to form/yield new products.

apply chargaffs decide how many guanine bases and length of DNA will have if it has 26 cytosine bases. explain.
Answer:
According to Chargaff's rule, if a DNA molecule has 26 cytosine base molecules it will also have 26 guanine molecules.
Explanation:
DNA is formed by the bases adenine guanine, thymine and cytosine, distributed in its two strands whose proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff found that in a DNA molecule the ratio of purine:pyrimidine is 1:1, so there should be the same amount of thymine as adenine and a similar amount of guanine for cytosine, according to the complementarity of the bases.
According to Chargaff, if a DNA molecule contains 26 cytosine bases —one pyrimidine— then it also contains 26 guanine molecules, one purine.
In the case that the molecule has a total of 100 nitrogenous bases, the amount of the other bases can also be known:
Cytosine 26 Guanine 26 Adenine 24 Thymine 24 Total 100What new details are you able to see on the slide when the magnification is increased to 10x that you could not see at 4x? What about 40x?
As the magnification increases, more specific information, such as the nucleus of cells on the slide, is seen.
What is magnification?
The majority of compound microscopes include objective lenses, which are replaceable lenses. The most popular magnification powers for objective lenses are 4x, 10x, 40x, and 100x, commonly referred to as scanning, low power, high power, and (usually) oil immersion objectives.
More minute characteristics of the cells and the form of the stained nuclei may be seen at a magnification of 40 times. You can see a smaller area of the specimen because of the reduced field of view at higher magnifications. Furthermore, keep in mind that although appearing to be incredibly thin, the item on the slide actually has a thickness.

3. Sketch a before and an after diagram of an animal cell placed in a hypotonic
solution
If an animal cell is placed in a hypotonic solution significantly for some period of time, it will eventually swell and finally burst. This process is known as cytolysis.
What is a Hypotonic solution?A hypotonic solution may be defined as a type of solution that typically contains a lower amount of solute as compared to the solute concentration in other solutions, across a semipermeable membrane.
According to the context of this question, when a cell is placed into a hypotonic solution, it will absorb the water content from outside and due to water consumption, it will swell and expand until it eventually bursts. This process of swelling and bursting of cells due to water consumption or absorption is known as cytolysis.
Therefore, if an animal cell is placed in a hypotonic solution significantly for some period of time, it will eventually swell and finally burst.

Lava lizards and the sea lion has a symbiotic relationship called commensalism.
When Sea lion take a nap, they attract flies and lava lizards feed on those flies and the sea lions apparently get rid of flies. In this act, flies does not harm sea lion and lava lizard get benefit.
Commensalism is defined as a symbiotic relationship between two organism in which one organism get benefit from other organism while causes no harm to the second organism.
