Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.

Answer:
B
Explanation:
I got it right :D
An important clue to the structure of DNA was provided by an X-ray diffraction photograph of DNA. Thus, the correct option is B.
What is X-ray diffraction?X-ray diffraction (XRD) is a widely used technique to assess the crystallinity and structure of the solid samples such as biomolecules like DNA and proteins. The crystal X-ray diffraction phenomenon results from the scattering process in which the X-rays are scattered by the electrons of the atoms which are present in the sample without any change in the wavelength.
Rosalind Franklin's X-ray diffraction method patterns of the DNA molecules rendered the important clue from which DNA has the structure of a double helical structure. The most famous X-ray photograph, the Photo 51 is still printed in most of the Biology textbooks.
Therefore, the correct option is B.

Explanation:
A botanist observes a large population of a particular type of beetle eating the leaves of one tree but not the leaves of a nearby tree. What should the botanist do first to study the interaction of these organisms in the ecosystem?
A. Remove the beetle population from the tree, and study them in the lab.
B. Identify the species of the beetle and the species of both trees.
C. Determine why the beetle is eating one tree but not the other.
D. Recommend a treatment that will keep the beetles from eating the trees.
ANSWER: B. identify the species of the beetle and the species of both trees (quizlet)
Answer: It's B,
"Identify the species of the beetle and the species of both trees."
The botanist should firstly study the interaction of these organisms in the ecosystem by identifying the species of the beetle and the species of both the trees. Therefore, the correct option is B.
What are species?A species is a group or organisms that can interbreed and produce viable offspring. The concept of species is used to define a unique type of organism, and it is the basic unit of biological classification.
Species are considered to be different from one another if they are unable to interbreed and produce offspring that can survive and reproduce. This definition of species is known as biological species concept.
In the case given in the question, the botanist should first identify the species of both the beetles and the trees. Then try to deduce a relationship between them which could clarify that the reason of the beetles feeding on those specific trees. Hence, the correct option is B.

Astronomers have two ways of measuring the brightness of a star, apparent magnitude and absolute brightness. Which statement best explains the difference between apparent magnitude and absolute brightness?
Answer:
Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs. (A light-year is the distance light travels in one year — about 6 trillion miles, or 10 trillion kilometers.) Astronomers also measure luminosity — the amount of energy (light) that a star emits from its surface.

Explain how an individual DNA mutation can become an adaptation in a population
Answer:
Explanation: Genetic variations that alter gene activity or protein function can introduce different traits in an organism. ... Over time, as generations of individuals with the trait continue to reproduce, the advantageous trait becomes increasingly common in a population, making the population different than an ancestral one.

At which part of the cell are electrical signals transmitted between nerve cells?
soma
axon
myelin sheath
dendrite
Dendrite is regarded as the part of the cell in which electrical signals are
transmitted between nerve cells.
Dendrites receive signals or communication from other cells and help to
transport the electrochemical charge from other neurons to the cell body or
axons which conduct them to the central nervous system for processing.
Dendrites have also been found to release neurotransmitters which makes
their study more complex and diverse.

What is point mutation?
what is silent mutation?
what is misssense mutation?
What is nonsense mutation?what is chromosomal mutation?
what is frameshift mutation?what is duplication?
what is insertion?
what is gene mutation?
what is deletion?
Answer:
Explanation:
A point (substition) mutation is when one base is substituted for another. A silent mutation is a type of point mutation. It is when one base is substituted for another but the amino acid does not change. The new codon that is made from the substitution still codes for the same amino acid as the original codon was suppose to. The protein made is still functional. A missense mutation is also a type of point mutation. It is when a one base is substituted for another causing the amino acid to change. It creates a nonfunctional, truncated protein. A nonsense mutation is the last kind of point mutation. It is when one base is substituted for another and the new codon made codes for a STOP amino acid. This makes a nonfunctional, truncated protein. A frame shift mutation is when the entire reading frame if the DNA sequence is changed. The two types of frame shift mutations are deletion and insertion. Deletion is when one nucleotide is taken away, or deleted from the DNA sequence. This will make a nonfunctional protein. Insertion is when a nucleotide is added to the DNA sequence. It makes a nonfunctional protein. Missense and nonsense mutations can also be frameshift mutations, but never silent. A chromosomal mutation occurs when the sister chromatids or homologous chromosomes fail to separate. Duplication is a type of chromosomal mutation where one chromosome have two copies of a gene or genes and the other no copies.
If all cells in your body contain the same set of DNA, why is it that some cells become muscles calls, some become skin, or nerve cells?
Answer:
This is due to CELL DIFFERENTIATION
Explanation:
All living cells are made up of the genetic material called DNA, which are exactly of the same sequence across all cells. However, the cells that contain the same DNA sequence are different in function.
This is as a result of a process called CELL DIFFERENTIATION, which is the process whereby cells specialize or become specific in function as a result of the expresssion or not of certain genes in the DNA sequence of each cell. In other words, cells might contain same DNA sequence but the genes are not all expressed at the same time, leading to the different function. Therefore, some cells become muscle cells, skin, or nerve cells with different functions.
