Answer:
C. Some bacteria possess a gene for bacterial resistance. These Bacteria are likely to survive a course or antibiotics and reproduce.
D. Bacteria contianing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce.
E. When someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. The bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce.
Explanation:
Genes that confer resistance to antibiotics provide a selective advantage to organism that are exposed to antibiotics. So, the correct option is B.
What is Antibiotic resistance?Antimicrobial resistance occurs when microbes develop mechanisms that protect them from the effects of antimicrobials, while all classes of microbes can develop resistance. Fungi develop antifungal resistance where as viruses develop antiviral resistance.
Antimicrobial resistance mechanisms is divided into four main categories:
(1) Limiting uptake of a drug
(2) Modifying a drug target
(3) Inactivating a drug
(4) Active drug efflux.
Thus, genes that confer resistance to antibiotics provide a selective advantage to organism that are exposed to antibiotics. So, the correct option is B.

Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism's genetic code—the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth. ... Proteins themselves are major structural elements of cells.
Bio molecules are related to the cell cycle such that they partake in the
numerous activities such as cell division that occur in cell cycle.
Bio molecules such as DNA and RNA store the genetic traits of the
organism. These traits are usually passed to the offspring during cell division
in the cell cycle. DNA contains other bio molecules such as protein which
forms the base pairs.
Cell division such as meiosis gives rise to four unique daughter cells and
mitosis gives rise to two identical cells. The bio molecules basically assist in
the passing of traits to their offspring.

B. Nastic responses are independent of the direction of the stimulus.
C. Tropisms require a stronger stimulus than nastic responses do.
D. Tropisms are independent of the direction of the stimulus.
Answer:
I think the answer is B hopefully this will help you
The difference between a tropism and a nastic response is the nastic responses are independent of the direction of the stimulus.
What do you mean by tropism?Tropism is a process in biology that denotes the expansion or rotation of an organism, typically a plant, in response to an environmental stimulation.
The presence of cellular receptors that allow for viral entry, the availability of transcription factors involved in viral replication, the molecular make-up of the viral tropogen, and the presence of cellular receptors.
Tropism is the growth toward or away from a stimulus. Plants tend to slant toward the light, as you may have seen. This is an illustration of a phototropism, a tropism in which light serves as the stimulus.

What animals have been dominant in the Cenozoic era
Explanation:
Cave lions, sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic era.
The Quaternary period was dominated by cave lions, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths. Plant life had a chance to thrive during the Cenozoic era without the dinosaurs.
What are the characteristics of Cenozoic era?From the Cenozoic period nearly 66 million years ago to the present day, life is considered recent.
Plants and animals look the one most like they do today during this time period.
The Cenozoic Era is divided into even smaller periods known as Epochs, so there will be even more guideposts in this Era.
Because of the extinction of many groups of giant mammals during the Cenozoic era, smaller species were able to thrive and diversify because their predators no longer existed.
Thus, big cats, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths monopolized the Quaternary period.
Plant life had a chance to thrive without the dinosaurs during the Cenozoic era.

Which statement correctly describes the flow of energy in photosynthesis?
Answer:
DPhotosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water. The passage describes a condition that is inherited.
Energy from the Sun flows into plants through photosynthesis, which is also known as “putting together with light,” and eventually into humankind. In the end, humans are powered by the Sun's energy to eat and survive. Thus, option D is correct.
What describes the flow of energy in photosynthesis?Solar energy is converted into chemical energy during photosynthesis, which produces glucose from water and carbon dioxide. The by-product is the emission of oxygen. In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.
Photosynthesis is the tremendous energy flow that underlies electricity and is the foundation of all life. Whether we are vegetarians or not, we joyfully devour our food without giving the basic mechanism that provides us with this gift even the least thought.
Therefore, Because energy is released when glucose is created from carbon dioxide and water, photosynthesis saves energy. The paragraph mentions a hereditary ailment.

Select
groups.
Between three and eight carbon atoms can be found in a monosaccharide, although only those with five (pentoses) and six (hexoses) are typically seen in nature.
What are the monosaccharides?The most prevalent monosaccharide is glucose, often known as dextrose or blood sugar. However, glucose accounts for a very minor portion of the total carbohydrates in a regular diet.
The majority of the time, glucose is only consumed when it is joined with other sugars to form a poly- or disaccharide.
The three monosaccharides that are most prevalent are glucose, fructose, and galactose. The monosaccharide category also comprises sugar alcohols and pentoses in addition to these three sugars.
Therefore, monosaccharides have a backbone of five or six carbon atoms.

a. 1/6
b. 1/9
c. 1/18
d. 1/36
e. none of these choices
Answer:
e. none of these choices
Explanation:
Remember, someone with an h.o.m.o.z.y.g.o.u.s gene basically inherits two identical alleles; one from their biological mother and the other their biological father.
In this scenario, the real concern should be to determine the probability that the girl child inherits a dominant allele that contains the gene that causes albinism. Hence, since there's little information about the gene type of the parents, a concise assumption can be made, thus rendering the listed options unlikely.
1. What other process can you think of that is similar to the journey of a signal through the neuron? For
example, a relay race can be similar to a neuron passing the baton to another neuron. Think of another
example and explain how.
Neurons are similar to other cells in body because: Neurons are surrounded by cell membrane. Neurons have nucleus that contains genes. It contain cytoplasm, mitochondria and other organelles.
what are neural signals?
Information from one neuron flows to another neuron across small gap called a synapse (SIN-aps). At synapse, electrical signals are translated into chemical signals in order to cross the gap. Once on other side, the signal becomes electrical again.
The transfer of information from neuron to neuron takes place through release of chemical substances into the space between axon and the dendrites. These chemicals are called neurotransmitters, and process is called neurotransmission. The space between the axon and dendrites is called the synapse
Neurotransmitter release from presynaptic terminal consists of a series of intricate steps:
1) depolarization of the terminal membrane
2) activation of voltage-gated Ca2+ channels
3) Ca2+ entry
4) a change in conformation of docking proteins
5) fusion of the vesicle to the plasma membrane
