Match the following terms and definitions.
1. cross-breeding; a method that unionizes gametes of differing genes to create a new individual
recombinant DNA
2. cultured DNA molecules from different biological sources
hybridization
3. a process of breeding organisms because of their specific traits
selective breeding
Answer:
Hybridization - a method that unionizes gametes of differing genes to create a new individual
Recombinant DNA - cultured DNA molecules from different biological sources
Selective breeding - a process of breeding organisms because of their specific traits
Explanation:
In biology, hybridization is the process of creating a hybrid by combining gametes of different species or varieties. An example of a hybrid is a liger - an offspring of a lion and a tiger.
Recombinant DNA is DNA created in the process of genetic recombination. Genetic material from multiple sources is combined, creating sequences that do not occur in the genome naturally.
Selective breeding is the process of breeding organisms with desirable characteristics. For example, a good dog breeder will breed only two completely healthy dogs in order to make sure that the puppies don't have any health issues often associated with the breed.

which of the following is not a difference between DNA and RNA ?
Group of answer choices
they have different phosphate groups in their backbones
They have different sugars in their backbones
DNA is a double strand and RNA is a single strand
RNA replaces thymine with uricel
Answer:
I believe the answer is:
They both have different phosphate groups in their backbones
Option A is correct. DNA and RNA have the same phosphate groups in their backbones.
DNA is deoxyribonucleic acid. DNA contains deoxyribose sugar. DNA is usually found in double strands. In DNA thymine is present.
RNA is ribonucleic acid. RNA contains ribose sugar. RNA is usually found in single strands. In RNA thymine is replaced by Uracil.
Nucleic acid is made up of phosphate group, ribose sugar, and nitrogenous bases.
Hence, options B, C, and D are incorrect.
Therefore, Option A is correct. DNA and RNA have the same phosphate groups in their backbones.

Scientists studied reproduction in the New Zealand mud snail to answer the question, “Are there benefits to reproducing sexually or asexually?” Which of these hypotheses would least likely aid the scientists as they worked to answer the question?
Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.
Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.
Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.
Answer:
Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
Explanation:
The main advantage of sexual reproduction is that it increases the genetic variation in the species by creating new combinations of alleles.
However, asexual reproduction produces more offspring, as it is usually a quicker method of reproduction. It also does not require the organisms to socialise to mate.
Sexual reproduction does not reduce the rate of mutation, which is influenced by environmental factors as well as the genome itself.
Answer:
Ur answer is D or Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

For many generations, a forest has been the home of a single species of bird; these birds primarily eat insects off the forest floor. One year, humans living in the area accidentally introduce a new
species of bird to the forest. This new species has the same diet as the existing species. Which description predicts what will most likely result from these two species of bird living in the same
ecosystem? (5 points)
O Both bird species cannot occupy the same niche and, therefore, one species will die off.
Both bird species would share the forest and have plenty of food and resources.
One bird species will adapt and feed on different organisms in the forest.

The established species will battle the introduced species of bird until death.
Answer:
Both bird species cannot occupy the same niche and, therefore, one species will die off.
Explanation:
Introducing a new species of bird will lead to competition among the organism. The food source will not be adequate for both species and competition will set in leading to survival of the fittest.
The population that best compete will most likely to chase away the other species who do not have food because hunger and starvation will lead to death of the other species and the species that is able to find food will survive and reproduce and remain in the niche.

strong winds.
severe lightning.
coastal flooding.
Answer:
A storm surge is characterized by coastal flooding.
Explanation:
A storm surge is a rise in sea level that occurs during tropical cyclones, intense storms also known as typhoons or hurricanes. The storms produce strong winds that push the water into shore, which can lead to flooding. This makes storm surges very dangerous for coastal regions.

Krusty was told that a certain itching powder was the newest best thing on the market; it even claims to cause 50 % longer lasting itches. Interested in this product, he buys the itching powder and compares it to his usual produce. One test subject (A) is sprinkled with the original itching powder, and another test subject (B) is sprinkled with the Experimental itching power. Subject A reported having itches for 30 minutes, Subject B reported to have itches for 10 hours.
Hi, you've asked an incomplete question. The full question reads;
1. Identify the:
Control GroupIndependent VariableDependent Variable2. Explain whether the data supports the advertisement's claims about its product.
Answer:
Subject AThe "certain itch powder"The time of itchinessExplanation:
1. Remember, the Control group in research often refers to the group in a research experiment that who are not subjected to any treatment, rather they are used as a comparison scale to see how other tested subjects perform.
We also need to note here that the independent variable here refers to a variable or factor that does not change (ie it is independent), but which results in changes in other variables. From the study, the "certain itch powder.""The time of itchiness" is a dependent variable because it does change, or can be affected by the independent variable.2. Remember, the advertisement of the "certain itching" "claims to cause 50% longer lasting itches". Hence, we can conclude that the data support the advertisement claims since subject B did itch over 50% longer than subject A. In fact, we are subject B itched for 10 hours, not the 30 minutes subjet A itched.

what is DNA fingerprinting
Answer: DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA
Explanation:
Answer:
DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.
Explanation:
A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect. Conversely, if the two DNA profiles do not match, then the evidence cannot have come from the suspect. DNA fingerprinting is also used to establish paternity.

The cell should be eukaryotic cell, as it is 5 micrometer in diameter.
What is eukaryotic cell?A nucleus, mitochondria, and an endoplasmic reticulum are membrane-bound organelles found in eukaryotic cells.
The nucleus of most eukaryotic cells contains the majority of the cell's DNA. The nucleus is the largest organelle in eukaryotes, measuring about 5 micrometers in diameter.
Eukaryotes are thought to have emerged from prokaryotes around 2.7 billion years ago, according to scientists.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells do not.
A nuclear membrane is found in eukaryotic cells. It contains mitochondria, Golgi bodies, and a cell wall.
It also has locomotory organs like cilia and flagella. The nucleus contains DNA, which contains all of the genetic information.
Thus, the cell is eukaryotic cell.

How does natural selection lead to the development of antibiotic-resistant bacteria?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
Survival of the Fittest (Natural Selection):
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
Answer:
This is super easy. In every population you have differences between the individuals in that population. If you apply a selection pressure to that population (like antibiotics to bacteria), you will kill all the bacteria that do not have the ability to withstand the drug. Thus, you have selected for those bacteria that happen to have a better ability to withstand it.

Chloroplasts are double membrane organelles with a smooth outer membrane and an inner membrane that is folded into disc-shaped sacs called the thylakoid. Thylakoids contain chlorophyll and other pigments (red, orange, yellow, brown) and are found in stacks
called granum (grana, plural.)
This organelle is used to:
A. perform the process of cellular respiration.
B. expell O2.
C. create ATP.
D. covert solar energy into chemical energy.
Answer:
D. convert solar energy into chemical energy.
Explanation:
Chloroplasts are the organelles that carry out photosynthesis. They contain chlorophyll, which traps light energy from sunlight to power chemical reactions that produce glucose.
The solar energy is converted into chemical energy, which is used to synthesise glucose, along with carbon dioxide and water. The reactions produce glucose and release oxygen as a byproduct.
Only ___________ cells can be viewed under an electron microscope because of the radiation it sends out.

What are the reactants for photosynthesis?
Explanation:
I think the equation shows that the “ingredients” for photosynthesis are carbon dioxide, water, and light energy.
Plants, algae, and photosynthetic bacteria take in light from the sun, molecules of carbon dioxide from the air, and water molecules from their environment and combine these reactants to produce food (glucose).

The______ of water molecules to each other helps transport water from the roots to the leaves in plants. When water warms or cools, either break or form. Thus, water absorbs or releases a great deal of_______ , helping to moderate temperatures. Because_______ is less dense than liquid water, it floats and protects lakes and oceans from freezing solid. Water is a versatile . Blood and other biological fluids are aqueous solutions with a diversity of dissolved .
Answer:
The correct words that film in the blanks are;
Polarity
Cohesion
Hydrogen bonds
Heat
Ice
Solvent
Solutes
Explanation:
Water is a highly polar molecule. Its polarity allows it to form strong intermolecular hydrogen bonds which accounts for the forces of cohesion in the water.
The hydrogen bonds form and break with evolution of heat hence accounting for the role of water in temperature regulation.
Ice is less dense than water due to spaces in the solid. Water is regarded as a universal solvent for polar solutes. Blood and other aqueous body clouds usually contains many dissolved solutes.
