The organism will be unable to replace cells through mitosis
The organism will not produce the protein coded by the gene
The organism will have fewer chromosomes.
The organism will create more daughter cells from meiosis.
Answer: The organism will not produce the protein coded by the gene.
Explanation:
The effect that will the mutation have on the organism is the organism will not produce the protein coded by the gene. Thus, the correct option for this question is B.
What is Mutation?A Mutation may be defined as the sudden, stable, and inheritable changes in the genetic material of organisms. The organism which undergoes mutation is known as a mutant. The agents of mutation are known as mutagens.
The Mutation leads to alterations in the genomic sequences of an organism. Due to this, the proteins formed are different compared to normal. The function of the previous protein is blocked and a new function is visualized.
So, if an organism has a mutation in a gene that blocks its function, the organism will definitely not be able to the protein coded by that gene.
Therefore, the organism will not produce the protein coded by the gene is the effect that will the mutation have on the organism. Thus, the correct option for this question is B.

The products of the glycolysis of one molecule of glucose can drive the citric acid cycle
Answer:
Since glycolysis of one glucose molecule generates two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, 10 NADH molecules, and two FADH2 molecules per glucose molecule
The products of glycolysis alone are not sufficient to directly drive the citric acid cycle (also known as the Krebs cycle or the tricarboxylic acid cycle).
However, the output of glycolysis, specifically pyruvate, is a crucial substrate that enters the mitochondria, where it undergoes further processing before entering the citric acid cycle.
The energy carriers, specifically NADH and FADH2, play a crucial role in driving the electron transport chain, the final step of cellular respiration.
The electron transport chain uses the energy from NADH and FADH2 to generate a large amount of ATP through oxidative phosphorylation.
Thus, while the products of glycolysis do not directly drive the citric acid cycle, they contribute to the overall energy production and supply the necessary substrates, such as acetyl-CoA, which is essential for the initiation of the citric acid cycle.

Darwin had seen these birds on a visit in the 1830s to the Galápagos Islands, a collection of islands in the Pacific Ocean to the west of South America.
What is Artificial selection?Artificial selection is the process of identifying desirable qualities in plants and animals and then taking action to strengthen and pass those traits on to succeeding generations.
Artificial selection operates in a similar manner to natural selection, with the exception that in natural selection, these judgments are made by nature without human intervention.
The physical characteristics and behaviors of many kinds of birds known as finches were highlighted by British naturalist and biologist Charles Darwin in his 1859 book On the Origin of kinds, which outlined the evidence for his hypothesis of evolution by natural selection.

After many years of normal function, a cell begins producing different proteins than it produced before. Propose two different explanations for this change.
Answer:
Explanation:
In order to produce different proteins, mutations must occur in the genetic material of the cell. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations: deletion, duplication, inversion, and translocation.
Cells are the functional unit that has a specific activity to perform. The alteration of the cell function can be due to gene or chromosomal mutations.
What are gene and chromosomal mutations?A change in the sequence of the DNA of the gene causes gene mutation and affects the gene or the part of the DNA of the chromosome. They occur in a single place and are called point mutations.
The point mutation is the alteration, addition, deletion or inversion of the single nucleotide base pair of the gene.
The chromosomal mutation affects the whole chromosome and alters the shape and size of the chromosomes. It leads to the increase or the decrease of the ploidy and structural shape.
Chromosomal mutation can be due to translocation, deletion, inversion and duplication of the chromosomes. Their increase or decrease affects the genome as a whole.
Therefore, alteration of the cell can be due to chromosomal or gene mutation.

Answer:
b. Altered chromosomes.
c. Changes in cell surface molecules.
e. Integration of viral deoxyribonucleic acid (DNA) into host chromosome.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
Transformed cells refer to cells that have undergone genetic alterations and as such do not experience normal cell processes or characteristics such as differentiation, division, and growth.
The characteristics which are typically associated with transformed cells include the following;
I. Altered chromosomes. Chromosomes are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
II. Changes in cell surface molecules.
III. Integration of viral deoxyribonucleic acid (DNA) into host chromosome.

Roger Sperry's chemoaffinity hypothesis Group of answer choices is supported by the orderly reinnervation of the frog optic tectum by regenerating retinal ganglion cells. was based upon his discovery of cell adhesion molecules in the optic tectum. relies on the random innervation of the optic tectum by retinal neurons correctly predicted that each optic tectal neuron-retinal axon pair would have a unique molecular lock-and-key recognition signal.
Answer:
is supported by the orderly reinnervation of the frog optic tectum by regenerating retinal ganglion cells
Explanation:
In vertebrates, the optic tectum represents the major part of the midbrain (mesencephalon), which is involved in the development of motor skills such as body movement, eye movement, vision, hearing, etc. In lower vertebrates such as, for example, frogs, the primary target of the optic nerve fibers (i.e., retinal ganglion cells) is the optic tectum, which is responsible for the visually guided behavior. Roger Sperry was a neurobiologist and pioneer brain researcher who won the Nobel Prize in Medicine for his investigations in neuroscience and experimental neurology. In 1940, R. Sperry made different experiments involving the visual system of frogs and he observed that when optic fibers are damaged they grow back to their original localization in the optic tectum in order to re-establish the original set of neural networks. From this observation, R. Sperry proposed his chemoaffinity hypothesis, which states that neurons have individual identification tags that specify synaptic networks.
Which of the following is NOT a place that releases enzymes for digestion?
Answer: D. esophagus
Explanation: Because esophagus uses muscles and does not use enzymes to digest. It only transports food to the stomach and then goes further into the digestive system.
Why not your mouth because it uses the enzyme Amylase, which helps break down complex carbohydrates. It is also produced by the mouth. Lipase, which breaks down fats. Protease is a protein-breaking enzyme that breaks down proteins.
Your stomach also uses enzymes as your intestine.

If a scientist wanted to follow Mendel’s experiment with a different kind of plant, which type of plant would she examine?
Answer: Pure line plant
Explanation:
Pure line plants are those plants that are used for breeding and selecting organisms with a desire trait to a number of generations until the wanted trait is established. Mendel had chosen pea plant for his experiments and that was a pure line species. It was bred to many generations so as to obtain the desired trait in successive generation. The plants were utilized to study the laws of inheritance. Also it was noticed that one trait being recessive in one generation will be expressive in other generation.

An unusually cold winter causes the squirrel population to decrease. This is an example of temperature as a
A. Carrying capacity
B. Limiting factor
C. Climax community
D. Pattern in space
Please and answer thank you!
Answer:
Most likely B
Explanation:
A - Carrying capacity is the amount of a species that can live in a given area with the given resources, weather does not apply.
B - Limiting factors are things such as food, mates, and competition with other organisms for resources, which can limit the maximum population. Temperature can be applied here, it is the best option.
C - Climax community is when an area's ecosystem is stable, so the term makes no sense used here.
D - To be honest I have no clue what this is. But making an assumption from the term, the winter being "unusually cold" does not make it a "pattern". So I don't think it's this option. I could be wrong, but I assume this is not the right choice.

When two gametes combine during fertilization to produce children with distinct DNA combinations, this variety is amplified even more, hence a, b, d is the correct option.
What is genetic variation?Crossing over and independent segregation occurs during meiosis I, DNA is exchanged between homologous chromosomes during prophase I when cells cross over.
New allele combinations are produced as a result, chromosomes can arrange themselves in a variety of ways on the metaphase plate, and this process is known as independent segregation.
In metaphase I, this happens, independent segregation but not crossing across occurs during meiosis II.
Therefore meiosis creates variation in the organism which leads to changes during evolution, hence a,b,d is the correct option.
