Answer:
mitochondria
Explanation:
Aerobic respiration is characteristic of eukaryotic cells when they have sufficient oxygen and most of it takes place in the mitochondria.
In eukaryotes, cellular respiration takes place in the mitochondria.
WHAT IS CELLULAR RESPIRATION:Cellular respiration is the process whereby living organisms obtain energy in form of ATP by breaking down food molecules in their cells. Cellular respiration occurs in the mitochondria of eukaryotic cells but in the cytoplasm of prokaryotic cells. The mitochondria is a double membrane organelle commonly termed the power house of the cell because of the supply of ATP.Therefore, in eukaryotes, cellular respiration takes place in the mitochondria.

These genes ___ from each other when ___ are formed. Alleles for different genes usually segregate ___ of each other.
Answer:
genes, alleles, dominant, sexually reproducing, two copies, segregate, gametes, independently
Explanation:
The inheritance of biological characteristics is determined by individual units called *genes*, which are passed from parents to offspring. Where two or more *alleles* of the gene for a single trait exist, some alleles may be *dominant* and others may be recessive. In most *sexually reproducing* organisms, each adult has *two copies* of each gene. These genes *segregate* from each other when *gametes* are formed. Alleles for different genes usually segregate *independently* of each other.

Which statement correctly describes an interaction between organelles in the model?
A
Letter U and letter S control the collection and release of waste from the cell.
В.
Letter T and letter R store the genetic material necessary for replication of the cell.
ОООО
C
Letter Q and letter S are responsible for creating and delivering nutrients throughout the cell.
D
Letter U and letter R are involved with the processes of transcription and translation for the cell.
Answer:
B) letter T and letter R store the genetic material necessary for replication of the cell
T-nucleus and R-mitochondria
The statement that correctly describes an interaction between organelles is : ( D ) Letter U and Letter R are involved with the processes of transcription and translation for the cell.
Letter U represents the Nucleus of the plant cell model attached while the Letter R represents the cytoplasm of the cell model.
The nucleus of a cell contains the genetic material ( DNA ) of the cell while the cytoplasm fills up the cell and is enclosed by the plasma cell membrane of the cell. Transcription involves the synthesis of RNA from a DNA template contained in the Nucleus and this process involves, The nucleus and cytoplasm of a cell.
Hence we can conclude that The statement that correctly describes an interaction between organelles is : ( D ) Letter U and Letter R are involved with the processes of transcription and translation for the cell.

Howmanychromosomes would be present in the sperm cells of a mosquito?
Answer:
23
Explanation:
Answer:
3
Explanation:
The only exception to the six chromosomes per cell rule for mosquitoes would be the gametes, or sex cells. When cells in the ovary or teste undergo meiosis, the result is egg or sperm cells which are haploid, meaning that they have just one copy of each chromosome, for a total of three chromosomes
The driving force presented by Wegener for his hypothesis was that continents ploughed through ocean crust.
Answer:
"Alfred Wegener suggested that continental drift occurred as continents cut through the ocean floor, in the same way as this icebreaker plows through sea ice. ... The supercontinent later broke apart and the continents having been moving into their current positions ever since. He called his hypothesis continental drift."

Could you explain the roles and relationships among producers, consumers, and decomposers, and identify the distinguished characteristics of several common relationships among organisms in an ecosystem near you?
Answer:
A consumer may also eat other consumers as food. When producers and consumers die, the Decomposer will come along to decompose (break down) the bodies of the dead producers and consumers into smaller chemicals - in short treating them as a food source
Explanation:
Your welcome have a good day :)
The producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.
What is an Ecosystem?The interaction between the organisms of different species plays their role in a systematic way as decided by natural selection, which is known as the Ecosystem.
Producers use light energy and inorganic matter to produce food. They are always present first in the ecosystem. Consumers take energy from plants known as herbivores, and also from herbivores known as Carnivores. Decomposers convert dead organic matter into inorganic matter. This inorganic matter helps producers perform metabolic activities. And finally, this cycle goes on.
Therefore, the producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.

Explanation:
Antibiotics interfere with prokaryotic cell functions. Streptomycin is an antibiotic that interferes with the proper binding of tRNA to mRNA in prokaryotic ribosomes. Which of the following best predicts the most direct effect of exposing prokaryotic cells to streptomycin?
A. Amino acid synthesis will be inhibited.
B. No mRNA will be transcribed from DNA
C. Posttranslational modifications will be prevented.
D. Synthesis of polypeptides will be inhibited.
Answer:
The correct answer is D. Synthesis of polypeptides will be inhibited.
Explanation:
Streptomycin is an aminoglycoside antibiotic. Aminoglycosides are actively transported across the bacterial membrane, irreversibly bind to one or more receptor proteins specific to the 30S subunit of bacterial ribosomes, and interfere with the initiation complex between messenger RNA and the 30S subunit. DNA can be misread, leading to the production of non-functional proteins; polyribosomes separate and are unable to synthesize proteins. This results in accelerated transport of aminoglycosides, thereby increasing the breakdown of the cytoplasmic membranes of the bacteria and consequent cell death. Streptomycin specifically binds and inhibits the ribosomes of bacteria because the ribosomes of prokaryotic cells are not the same as those of eukaryotic cells. Specifically, it blocks the normal activity of the initiation complex, thereby halting protein synthesis and, on the other, it causes the incorporation of other amino acid different than the one encoded.
A medicine or substance that inhibits the growth and infection of bacteria and other agents are called antibiotics. They treat and prevent microbial or bacterial infections.
On direct exposing of prokaryotic cells to streptomycin, the option D. synthesis of polypeptides will be inhibited.
The mechanism of antibiotics can be explained as:Streptomycin is a type of antibiotic that is aminoglycoside in nature which binds to the protein receptors and interferes with the initiation complex present between the ribosomal unit and mRNA.The interference can cause misleading information read by the DNA and as a result producing non-functional proteins or no synthesis of proteins.This misleading information will result in an increased amount of aminoglycosides transportation across the membrane of bacteria and its degradation.It binds to the ribosomal unit of bacteria as they are unique to them and not eukaryotes so that they do not harm eukaryotic organisms.Therefore, antibiotics block polypeptide synthesis.
