Answers
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.

How does natural selection lead to the development of antibiotic-resistant bacteria?
Answers
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.

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
Answers
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.

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 might the digestive system and the immune system interact to help protect the body?
Please i need a correct and accurate answer. ++ giving brainliest
Answers
Answer:
Around 70% of our immune system dwells in our digestive tract in the form of gut-associated lymphoid tissue (GALT). An important component of our immune system called plasma cells (which give rise to invader-defending antibodies) also reside within the GALT. Our gut is the major channel between the external environment and the internal systems of our body. It is exposed to plenty of germs and harmful invaders such as bacteria and viruses present in food particles on a daily basis. [1] These toxic agents are perceived by the immune system in the gut as being harmful to our body and attacked. That being said, our body does not reject everything we put into it. This process is known as tolerance. When our immune system rejects an otherwise harmless substance, we are labeled as being sensitive or allergic to that food/food ingredient.

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.

The established species will battle the introduced species of bird until death.
Answers
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.

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.

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.
Answers
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.
