A. It is a mammal.
B. It is an invertebrate.
C. It goes through complete metamorphosis.
D. It goes through incomplete metamorphosis.
Answers
Answer:
D. It goes through incomplete metamorphosis.
Explanation:
Damselflies do not hide away inside a pupa to transform into their adult form. Instead, they shed their skin several times as they grow, changing shape a little each time. This process is called incomplete metamorphosis.
Recall in class the example of incorporating heavy or light nitrogen labels into DNA to investigate how DNA is replicated. Imagine if, instead of labeling DNA, the experiment used heavy labeled RNA bases. What would be the outcome if you examined the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases?
Answers
Answer: You would not notice any difference or any labeled base, because RNA is not used to make DNA.
Explanation:
DNA is a molecule that contains the genetic information in all living things. The molecule consists of two strands that wind around each other to form a double helix structure where the strands are joined by hydrogen bonds. It is a nucleotide polymer where each nucleotide consists of a sugar called deoxyribose, a nitrogenous base (which can be adenine, thymine, cytosine or guanine) and a phosphate group (derived from phosphoric acid). What distinguishes one polynucleotide from another, is the nitrogenous base and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information.
Consider that DNA replication is semi-conservative, which means that each strand of the DNA double helix functions as a template for the synthesis of a new complementary strand. This process leads from one starting molecule to two "daughter" molecules, in which each new double helix contains one new and one old strand. Then, if nitrogen tags are incorporated into the DNA, they will register on the old strand of the new DNA molecule.
On the other hand, RNA (ribonucleic acid) is a molecule similar to DNA but has only one strand and consists of a sugar (ribose) and alternating phosphate groups. Attached to each sugar is one of the four bases adenine, uracil, cytosine or guanine. The process of RNA synthesis, called transcription, consists of making a complementary copy of a piece of DNA. During this process, an enzyme called ARN polymerase, adds nucleotides that are complementary to the DNA strand. Then, this new RNA strand has new nucleotides. Thereby, if you examine the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases, you would not notice any difference or any labeled base, because RNA is not used to make DNA.
For each - choose either peroxisome or lysosome, both or neither Group of answer choices uses hydrolases lysosome uses the enzyme catalase peroxisome is one of the main sites of fatty acid breakdown peroxisome combines with endosomes to digest ingested matter lysosome capable of converting hydrogen peroxide to water and oxygen peroxisome destroys engulfed bacteria both lysosome and peroxisome main role is metabolism both lysosome and peroxisome digestive interior is acidic lysosome proteins are derived from the endoplasmic reticulum
Answers
Answer:
Uses hydrolases -lysosome
Uses the enzyme catalase- peroxisome
Is one of the main sites of fatty acid breakdown- peroxisome
Combines with endosomes to digest ingested matter- lysosome
Capable of converting hydrogen peroxide to water and oxygen- peroxisome
Destroys engulfed bacteria- lysosome
Main role is metabolism- both lysosome and peroxisome
Digestive interior is acidic- lysosome
Proteins are derived from the endoplasmic reticulum- Peroxisome
Explanation:
The lysosome is a membrane-bound organelle found within a cell whose main function is to ensure the break down of biological polymers, such as proteins and polysaccharides. It is comprised of enzymes that are degradative in nature that can degrade biological polymers such as proteins, nucleic acids, lipids, etc. They contain various types of hydrolytic enzymes such as proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatase. These enzymes are acid hydrolases as they function in the acidic environment of the lysosome. Lysosomes are also used by the cell to destroy invading viruses and bacteria.
Peroxisomes are membrane-bound organelles found within the cytoplasm of a cell. They are derived from the edoplasmic reticulum. Peroxisomes are involved in lipid biosynthesis, for example, cholesterol and dolichol are synthesized in peroxisomes. Peroxisomes are also involved in the synthesis of bile acids from cholesterol.
Peroxisomes contain enzymes that oxidize fatty acids and amino acids. Peroxisomes also contain enzymes such as catalase that convert hydrogen peroxide to water and oxygen preventing oxidative damage by these reactive oxygen species.
What influences other than humans affect genetic drift in populations?
Answers
Answer:
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.
Explanation:
How did NASA help to uncover the adaptations that are made due to living in extreme environments?
By analyzing changes in one twin on Earth and the other in space.
By introducing animals and other organisms that could be studied in space.

Answers
Answer:
A) A = ATP
B) B = CO2 + H2O
D) D = O2 + C6H12O6
Explanation:
The process of photosynthesis and cellular respiration mutually depends on one another. In this diagram, A represents ATP, B represents C[tex]O_2[/tex] + [tex]H_2O[/tex], C represents sunlight, and D represents [tex]C_6H_1_2O_6 + O_2[/tex].
What do you mean by Photosynthesis?Photosynthesis may be defined as a process through which plants synthesize their own food with the help of carbon dioxide and water in the presence of sunlight.
Mitochondria release energy in form of ATP, while carbon dioxide and water serve as the reactant for photosynthesis. In presence of sunlight, they convert into glucose and oxygen which is the product of photosynthesis.
Both photosynthesis and cellular respiration mediate the cycling of matter like oxygen, glucose, carbon dioxide, etc.

Answers
Complete question:
The offspring produced between two given types of plants can be any of the three genotypes, denoted by A, B and C. A theoretical model of gene inheritance suggests that the offspring of types A, B and C should be in a 1:2:1 ratio (meaning 25% A, 50% B, and 25% C). For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded in the table below.
Genotype Observed frequency
A → 18 individuals
B → 55 individuals
C → 27 individuals
Do these contradict the genetic model?
Use a 0.05 level of significance.
Determine the chi-square test statistic.
Answer:
Do these contradict the genetic model? No, according to the chi-square test, there is not enough evidence to reject the null hypothesis of the population being in equilibrium.
Explanation:
Available data:
Crossed genotypes: twoGenotypes among the offspring; Three → A, B, and CExpected phenotypic ratio → 1:2:1Total number of individuals, N = 100A = 18 individualsB = 55 individualsC = 27 individualsSo, let us first state the hypothesis:
H₀= the population is equilibrium for this locus → F(A) = 25%, F(B) = 50%, F(C) = 25% H₁ = the population is not in equilibriumNow, let us calculate the number of expected individuals, according to their expected ratio.
4 -------------- 100% -------------100 individuals
1 --------------- 25% -------------X = 25 individuals A
2 -------------- 50% -------------X = 50 individuals B
1----------------- 25%--------------X = 25 individuals C
A B C
Observed 18 55 27 Expected 25 50 25 (Obs-Exp)²/Exp 1.96 0.5 0.16(Obs-Exp)²/Exp
A) (18 - 25)²/25 = 49/25 = 1.96
B) (55 - 50)² / 50 = 25/50 = 0.5
C) (27 - 25)²/25 = 4/25 = 0.16
Chi square = X² = Σ(Obs-Exp)²/Exp
∑ is the sum of the terms O are the Observed individuals: 2 in chamber B, and 18 in chamber A. E are the Expected individuals: 10 in each chamberX² = ∑ ((O-E)²/E) = 1.96 + 0.5 + 0.16 = 2.62
Freedom degrees = 2
Significance level, 5% = 0.05
Table value/Critical value = 5.99
X² < Critical value
2.62 < 5.99
These results suggest that there is not enough evidence to reject the null hypothesis. We can assume that the locus under study in this population is in equilibrium H-W.

The CDC has categorized several infectious agents based on the seriousness of their antibiotic resistance. Neisseria gonorrhoeae, the causative agent of gonorrhea, is one of several agents in the "Urgent Threat" category. Gonorrhea is also the second most common reportable disease in the United States. This makes gonorrhea a significant public health concern. Please locate this article through an online search engine: Kirkcaldy RD, Harvey A Papp JR. et al.

Explanation:
Neisseria gonorrhoeae is a gram negative bacteria known to cause the sexually transmitted infection called Gonorrhea. Gonorrhea is easily treated with antibiotics, as long as the patient seeks early care and discovers the disease early on, as it can be asymptomatic, especially in women. When left untreated, Neisseria gonorrhoeae can infect the nervous system, causing many problems and even leading to death.
Despite being known to attack the urogenital system, this bacteria can attack the eyes generating gonococcal conjunctivitis, which is also sexually transmitted.
Neisseria gonorrhoeae is a fastidious bacteria, which means that it only grows in specific, selective and enriched culture media.

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period of time.
In the primary succession, species like algae, fungi, and lichens are preset. In the secondary succession, the pioneer species present, that already existed in the environment.
What are primary and secondary succession?One of two types of biological and ecological succession of plant life. They are primary succession that takes place in environments where fresh substrate is deposited that is devoid of plants and other species that typically lack soil, such as lava flows or areas left behind from glaciers that have receded.
