A. organelle
B. organ
C. endoplasmic reticulum
D. flagella
Answer:
A structure within a cell that performs a specific function is an organelle.
Explanation:
An organelle is a structure inside the cell that preforms functions that are necessary for the cell.
Examples of organelles are the ER, the Golgi Apparatus, and the Mitochondria.
Hope this helps.
A structure within a cell that performs a specific function is an organelle. An organelle is a subcomponent of a cell.
What are cell organelles?Cell organelles are the ultrastructure's present in the cell and they show division of labor.
These organelles perform specific function for the cell and thus constitute the framework of all living organisms.
The basic structure of cell contains a plasma membrane, nucleus and cytoplasm. However, ultra-microscopic structures are embedded in the cell cytoplasm and they are designated as organelles in a cell.
Endoplasmic reticulum, Golgi apparatus, mitochondria, ribosomes, microtubules, lysosomes etc. are the specialized organelles present in cell.
Each of these organelles perform specific function. For instance, mitochondria help in energy production, Golgi helps in protein modification and packaging.
Cell organelles are thus important structural and functional elements of a cell.

Which conditions are required for natural selection? Select three options. Populations have genetic variation.Organisms overproduce offspring.Environmental conditions remain stable.Traits are passed on to only some of the offspring.Nature selects favorable adaptations.
The conditions required for natural selection are populations have genetic variation, organisms overproduce offspring and nature selects favorable adaptations.
What is natural selection?"Natural selection is the process through which populations of living organisms adapt and change."In order to adapt and survive in a changing environmental conditions, the organisms undergo into some changes (changes in traits) over time which leads to genetic variation among them. The best adapted characters/traits of organisms will survive and will creates its progeny (having new traits). It means that nature selects the most favorable adaptations.What do you mean by genetic variation?"It is a term used to describe the variation in the DNA sequence in each of our genomes."What is adaptation?"It is the biological mechanism by which organisms adjust to new environments or to changes in their current environment."Example: To reduce transpiration leaves of some plans are modified into spines.Hence, the correct options are: 1. Populations have genetic variation. 2. Organisms overproduce offspring. 5. Nature selects favorable adaptations.

Which best explains the genetic similarities between species? A. More closely related species will have identical dna B. More closely related species will have fewer dna similarities C. More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna
Answer:
C
Explanation:
The correct answer would be that more closely related species will have more similarities in DNA.
The DNA stores the genetic information of organisms and contains a set of instructions that defines how organisms look. It is usually used to delimit species with closely related species of organisms having similar DNA. The more related species are, the more similar their DNA would be and vice versa because the similarity in the DNA of organisms is often used as an indication of descending from a common ancestor.
The correct option is, therefore, C.
Genes are the hereditary unit of life, which carries the information from parent to daughter cells. The organisms belonging to the same species will have the same genetic sequence.
The correct answer is:
Option C. More closely related species will have more similarities in DNA
The DNA stores the genetic information of the organisms and codes for the traits of the organism.
The genes delimit the species' relativity of the organisms. The species that are closely related will have more similarities in the genetic sequence.
The similarity of the genes or DNA is often used as an indication of descending of species from a common ancestor.
Therefore, option C is correct.

____________ polymerase is used to add new RNA nucleotides to make RNA.
RNA polymerase is used to add new RNA nucleotides to produce RNA.
RNA polymeraseIt is the enzyme responsible for copying the sequence of DNA into the sequence of RNA during the process of transcription.
The information encoded in DNA is used to produce RNA during the process of transcription.
The production of RNA takes place by the enzyme RNA polymerase, by using the antisense strand of the DNA as the template by supplementing the complementary RNA nucleotides to the 3 prime terminal of the developing strand.
The enzyme RNA polymerase combines with the DNA at a sequence known as the promoter at the time of the beginning of transcription.
Thus, the given blank can be filled with RNA.

ASAP IMAGE IS ATTACHED THIS IS NOT DIFFICULT
There are only 4 types of nucleotides in mRNA and 20 types of amino acids in proteins. This figure shows how 4 types of nucleotides can provide a unique code for each of the 20 types of amino acids.
6a. The mRNA code for each type of amino acid is a
sequence of _______ nucleotides, called a codon.
(2 / 3 / 4)
6b. In the figure, which mRNA codon codes for the amino acid Phe?
Answer:
The mRNA code for each type of amino acid is a sequence of three nucleotides, called a codon.mRNA codon that codes for the amino acid Phe es UUU.Explanation:
The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:
An amino acid can be encoded by more than one codon. From these combinations the three STOP codons are obtained.A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.
Phenylalanine (Phe), according to the image, is formed with the UUU codon.

Answer:
The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

What height in meters must the student climb in order to reach the top of the hill?
Answer: 256 or 300 sorry if i was incorrect
Explanation:
The student must reach the top of the hill, and this is entirely dependent on the hill's elevation, which varies from one area to the next and is not constant in any particular area.
What is the significance of the hill in the ecosystem?The hill is the highest point on Earth and plays an important role in ecosystems because it can provide a variety of different habitats for plants and animals as well as act as barriers that separate different ecosystems, such as the forest ecosystem present on one side of the hill from the grassland ecosystem present on the other side of the hill, and it is also a depositary of minerals and other resources.
