How would you describe the process of genetic information being passed from parent to offspring in organisms like bacteria?
A. The organism undergoes mitosis and creates genetically diverse offspring
B. The organism undergoes meiosis and creates genetically diverse offspring
C. The organism undergoes binary fission and creates genetically identical offspring
D. The organism undergoes sexual reproduction and creates genetically identical offspring
Answer:
C. The organism undergoes binary fission and creates genetically identical offspring
Explanation:
This because binary fission is the means of reproduction in prokaryotic organisms like bacteria. This refer to the process where a single cell divided into two or more and each looking more exactly like the parent cell..
the process of binary fission, a particular parent cell replicate its genetic material or DNA and then divides into two parts by a process called cytokinesis and each new organism produced then receive one copy of DNA. This occur in bacteria

in VDJ recombination occurs in the Group of answer choices variable region of the heavy chain. constant region of the light chain. variable region of the light chain. Both the light and heavy chain.
Answer:
constant region of the light chain.
Explanation:
The VDJ recombination is defined as the process where the T cells as well as the B cells are randomly assembled from the different gene segments. These are mainly known as the variables (V), the diversity (D) and the gene (G). This is done in order to generate the unique receptors which is also called as the antigen receptors so that they can collectively recognize the different types of the molecules. It mainly occurs in the constant region of the light chain.
A ________ is a unicellular or multicellular organism that is heterotropic; feeding off dead organic matter or a parasite, feeding off living organisms; reproduces through spores.
Answer:
A fungi is a unicellular or multicellular organism that is heterotropic; feeding off dead organic matter or a parasite, feeding off living organisms; reproduces through spores.
Explanation:
FUNGI -: Fungi can be single-celled organisms or multicellular organisms with a great deal of complexity. They can be found in almost any habitat, but the majority of them reside on land, primarily in soil or plant material, rather than in the sea or fresh water. Decomposers are organisms that live in the soil or on dead plant materials and play a vital part in carbon and other element cycling. Some are plant parasites that cause illnesses such mildews, rusts, scabs, and canker. Fungal diseases in crops can cause a farmer to lose a lot of money. Animals are afflicted by a small number of fungus. Athletes' foot, ringworm, and thrush are examples of human skin diseases.
Fungi play an important part in the breakdown of organic materials and in the cycling and exchange of nutrients in the environment. They've long been utilized as a direct source of human food in the form of mushrooms and truffles, as a bread leavening agent, and in the fermentation of a variety of foods like wine, beer, and soy sauce.
Hence , the answer is fungi.

A newly developed drug causes users to lose some muscle control and slur their words, The drug also results in a slowing of central nervous system activity. Depressants slow the central nervous system.
What is Nervous system?Signals are sent from the brain to the rest of the body, including the internal organs, via the nervous system. Thus, the nervous system's activity regulates a variety of functions, including the capacity to move, breathe, see, and think.
The nerve cell, or neuron, is the building block of the neurological system. There are around 100 billion neurons in the human brain. A neuron has a cell body, which contains the cell nucleus, as well as distinct extensions known as axons and dendrites.
Different neuronal types control or carry out various functions. For instance, motor neurons help the brain send signals to the muscles that cause movement.
Therefore, A newly developed drug causes users to lose some muscle control and slur their words, The drug also results in a slowing of central nervous system activity. Depressants slow the central nervous system.

A rare orchid has been found in the mountains in China.
The orchid has pale yellow flowers.
DNA analysis of the genome shows that it is an ancestral species.
All other present day orchids evolved from this ancestral species millions of
years ago.
One present day species has bright purple flowers.
Describe how an orchid with bright purple flowers may have evolved from the
ancestral species which has pale yellow flowers.
[4 marks]
Answer:
a mutation in the germinal line changed the phenotype to bright flowers which were capable of attracting more pollinators compared to yellow flowers. Subsequently, this mutation was selected by natural selection, thereby increasing its frequency in the population
Explanation:
A mutation is any change in the nucleotide DNA sequence of the genome of a particular organism. Mutations can be divided into 1-germinal mutations (i.e., mutations that occurred in the gamete cells) which can be passed on to offspring, and 2-somatic mutations (i.e., mutations that occurred in the somatic cells), which cannot be inherited. Moreover, mutations can be neutral, deleterious or beneficial depending on the environment in which the organism lives. When a germinal mutation is beneficial, the organism carrying the mutation will have more chances to survive and reproduce (i.e., a higher adaptive fitness), thereby the organism will have more chance to pass this mutation to the next generation and the mutation will increase its frequency in the population.

Hemophilia is a rare recessive genetic disorder in which the recessive version of the gene does not produce blood-clotting factors. A woman whose father had hemophilia marries a normal man. They have two children: a boy and a girl. What are the chances of the boy being a hemophiliac? _________ What are the chances of the girl being a hemophiliac? _________ Show your work with a Punnett Square.
Answer:25 , 0
Explanation:
XX©(mother being the carrier as her father was hemophilia- females can only be carrier of hemophilia ) when crossed with normal father produces offspring XX©, XY, XY©, XY. Therefore chances of boy being hemophilia=(1/4)*100=25.
Chances of girl being hemophilia= 0.

Answer:
Both earthquake and volcanoes are concentrated in specific regions.
Explanation:
The distribution of earthquake on earth is concentrated in specific zones where the plate tectonic meets or fuse with each other. Volcanoes are also concentrated in specific regions on the earth. Most volcanoes are concentrated on the edges of continents, on island chains, or long mountain ranges beneath the sea. There is a great relationship between earthquake and volcanoes because volcanic eruptions is the cause of earthquake in a region.

not sure but hope it helps
Mt. Mayon examples is NOT classified as composite volcano.
What is Composite volcano?Cone-shaped composite volcanoes, also known as stratovolcanoes, are formed from numerous layers of lava, pumice, ash, and tephra. Composite volcanoes typically generate tall peaks rather than rounded cones because they are composed of layers of viscous material rather than fluid lava.
Calderas are occasionally created when the peak crater collapses. The most destructive volcanic eruptions in recorded history have been caused by composite volcanoes.
Apart from Earth, Mars is the only known location in the solar system with stratovolcanoes.
Therefore, Mt. Mayon examples is NOT classified as composite volcano.
