DNA is an example of a nuclei case acid true or false
Answer:
The term nucleic acid is the overall name for DNA and RNA.
Explanation:
They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base. ... The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

The golden-cheeked warbler and the black-throated green warbler look nearly identical to each other. What type of information could be used to determine if the birds are separate species? Select all that apply. The birds breed with each other where their territories overlap. The birds breed with each other where their territories overlap. The birds show differences in mating songs and behaviors. The birds show differences in mating songs and behaviors. The birds do not breed with each other where their territories overlap. The birds do not breed with each other where their territories overlap. The birds compete for food and nesting sites. The birds compete for food and nesting sites.
Answer:
The birds do not breed with each other where their territories overlap.
Explanation:
The correct answer would be that the birds do not breed with each other where their territories overlap.
A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.
Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid.
Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.
When we talk about soil depletion, which soil horizon are we talking about? Thank you
Answer:
Surface Horizon (A)
Nutrient depletion of soils is a widespread soil degradation phenomenon that occurs as a consequence of soil erosion (it is the topsoil in which generally most soil nutrients are present that erodes fastest) but also because of poor management practices, such as slash and burn and other subsistence agricultural.

how does cell division help in growth and development of somatic cells and in gamete formation?
════════ ∘◦❁◦∘ ════════
[tex] \mathbb{CELL\:DIVISION\:(MITOSIS)} [/tex]
════════════════════
Well, im not sure what somatic cell is. But, the reason why cell division help in growth and development is because the main goal of cell division is to make more cells right? This is also why we keep growing (like taller/bigger) because more cells in our body because of that cell division.
#see pic of how cells in our body divide during mitosis
#sorry i borrow this ans for my latex experiment :v
════════════════════
Mitosis occurs in somatic cells this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

List the four steps of mitosis in order. Describe what is happening during each phase.
Answer:
The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we'll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis. During the four phases of mitosis, nuclear division occurs in order for one cell to split into two.
Explanation:
1. DNA 2. Helicase 3. DNA Polymerase 4. DNA Replication 5. Pyrimidine a. Double stranded molecule that has a deoxyribose sugar. b. The end-product of this process are two identical copies of DNA. c. Enzyme that breaks hydrogen bonds to unwind and unzip DNA. d. Nitrogen containing base that has a single ring as its molecular structure. Thymine and Cytosine are an example of this type of molecule. e. Enzyme that covalently bonds sugars and phosphates during DNA replication.
Answer:
1. DNA-A.Double stranded molecule that has a deoxyribose sugar.
2. Helicase- C. Enzyme that breaks hydrogen bonds to unwind and unzip DNA
3.DNA Polymerase- E. Enzyme that covalently bonds sugars and phosphates during DNA replication
4.DNA Replication-B. The end-product of this process are two identical copies of DNA.

Explanation:
What is the the process responsible for the synthesis of proteins and mention the cellular structure where the genetic program responsible for this synthesis is located.
Answer: Translation
Explanation:
During the transcription the double stranded DNA act as a separate template strand to produce mRNA molecule. The mRNA molecule encode for amino acid chain that collectively forms the protein. The ribosomes are the sites of protein synthesis the mRNA get attached to the ribosome. Within the ribosome the rRNA molecule instruct the catalytic steps for the synthesis of protein. The amino acid sequence or chain gets stitched together to form the protein.
What epigenetic marker changes cause chromatin to open up?
Answer Several lifestyle factors have been identified that might modify epigenetic patterns, such as diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress, and working on night shifts.:changes to the histone tails act indirectly on the DNA. For example, lysine acetylation may create a binding site for chromatin-modifying enzymes (or transcription machinery as well). This chromatin remodeler can then cause changes to the state of the chromatin. hope this helps ❤️❤️❤️
Explanation:
The changes with respect to the epigenetic marker should result to the chromatin at the time of opening up because When transcription factors could access the DNA binding sites.
Reasons of chromatin:It is the material that comprises of the chromosome that involved the DNA and protein. The major protein is called as the histones. It should be acted as the packaging elements with respect to the DNA.
Therefore, The changes with respect to the epigenetic marker should result to the chromatin at the time of opening up because When transcription factors could access the DNA binding sites and the gene expression is not be blocked.

The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced round seeds. However, in the fifth generation, the plant produced to two plants with wrinkled seeds. Can that be possible? Explain your answer using your pedigree chart.
Answer:
Explanation:
This happened because two fully recessive plants where introduced into the lineage. these plants where paired with the dominate verison. this would make all of the offspring have the two traits. this being said it would make it possible for the offspring to be Wrinkled Seeds.
When two heter0zyg0us individuals are crossed -simple d0minant inheritance-, or a heter0zyg0us individual is crossed with a h0m0zyg0us recessive one, they can produce h0m0zyg0us recessive subjects among the progeny. Heter0zyg0us individuals among the fourth generation got crossed with another plant (h0m0zyg0us recessive or heter0zyg0us) and produced two h0m0zyg0us recessive plants expressing wrinkle seeds.
---------------------------
The first step is to understand the given information. So,
The first four generations produced round seedsPlants that fertilized these plants also produced round seeds (see generation II) Among the fifth generation there are two plants with wrinkled seedsLet us assume that a diallelic gene determines the shape of seeds.
D0minant allele R codes for round seedsRecessive allele r codes for wrinkle seedsNow, let us analyze the pedigree. According to the information provided here, we can tell that
black figures represent h0m0zyg0us d0minant individuals, grey figures represent heter0zyg0us individualsempty figures represent h0m0zyg0us recessive individualsRemember that Generations are represented with roman numbers.
We will name the plants with numbers from 1 to 26.
According to the information in the statement and the information in the pedigree, we can say that grey individuals from the fourth generation are heter0zyg0us expressing round seeds. They can produce wrinkle seeds, if they are fertilized by another heter0zyg0us plant or a h0m0zygous recessive one.
Option 1:
Two heter0zyg0us plants are crossed, and their offspring have wrinkled seeds.
Option 2:
One heter0zyg0us plant is crossed with a h0m0zyg0us recessive one, and their offspring have wrinkled seeds. Let us see the cross

When a plant or animal is no longer found anywhere on Earth, it is described as
being
locally extinct
geographically extinct
biologically threatened
biologically extinct
Answer:
B. Geographically extinct
Explanation:
Lets take a moment to look at the words provided. Geographical means physical features of an area, or relating to geography. It can also relate to when we are talking about information on the Earth's surface. Extinct means that the organism is no longer alive, and that there are none left of its species. So, putting the two words together, geographically extinct means that the organism is no longer found on Earth.

A family business had bred dogs for over 250 years. During this time, 125 generations of dogs were bred for a single trait: protective instincts. Immediately after
birth, the puppies are sorted based on whether or not they have a white patch of fur on their chests. Those without this trait, are no longer bred for their
business and instead are adopted to pet stores and not private sales for people requesting the desired trait of protective instincts.
How could the breeders know these other dogs will not have the traits they are looking for when they are just new-born puppies?
Answer:
They can know if the trait has been carried on by looking at the bred dogs that have the trait and determining if the trait has been passed down by similar characteristics between the parent with the trait and the puppy that could have the trait.

Photosynthesis-
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ... In like manner, carbon dioxide passes from blood to the alveoli and exhaled after
