A chromosome is a cellular DNA molecule that typically encodes thousands of genes. In order for the information encoded within a specific gene to be transcribed to make RNA, RNA polymerase begins to transcribe the DNA, using one DNA strand as a template to make a complementary RNA molecule that is later used for protein synthesis during translation. A scientist is studying two mutant bacterial strains that do not produce a functional form of amylase, an enzyme that the organisms use to break down starch polymers. The scientist is using a third bacterial strain capable of normal amylase production (called the wild type) for comparison. Upon sequence analysis of the DNA region around and including the amylase gene in all three bacterial strains, the scientist locates the mutations as shown. Which statement BEST explains how these mutations affect gene expression and amylase enzyme functionality in the mutant bacterial strains?
A. Only mutant #1 transcribes the amylase gene and translate the resulting mRNA, but the resulting enzyme is non-functional
B. Only mutant #2 transcribes the amylase gene and translates the resulting mRNA, but resulting enzyme is non functional
C. Neither mutant #1 nor mutant #2 transcribes the amylase gene nor complete translation, so neither make functional enzymes
D. Both mutant #1 and mutant #2 transcribe the amylase gene and translate the resulting mRNA, but both resulting enzymes are non- functional.
Answer:
B. Only mutant #2 transcribes the amylase gene and translates the resulting mRNA, but resulting enzyme is non functional

In your own words , describe how genetic drift , bottlenecks , and the founders' effect csn result in speciation:
Answer:
- Genetic drift: speciation by the accumulation of mutations
- Bottlenecks: the emergence of subpopulations genetically distinct to the original species may contribute to speciation
- Founders' effects: new environments contribute to the emergence of genetic changes and therefore drive evolutionary processes such as speciation
Explanation:
Genetic drift is an evolutionary mechanism in which the allele frequencies in the population change by chance over time. This mechanism can facilitate the emergence of new species due to the accumulation of mutations and population subdivision. Moreover, a bottleneck is a genetic phenomenon associated with a drastic reduction in the size of a population. A genetic bottleneck may lead to the loss of genetic variation and consequently also speciation through population subdivision. Finally, a founder-effect can be defined as an event associated with the colonization of a new environment, which may lead to rapid genetic changes and thus favor evolution (speciation).

Describe the roles of DNA and genes in inheritance and genetic variation.
Answer:
First, there is only one type of DNA! ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made. There is a complication that some amino acids have more than one code which specifies it - there are plenty of examples where a change of codes (eg a mutation) can result in NO CHANGE in the amino acid which is specified. Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit.

Use the drop-down menus to complete the statements. In the first step of meiosis I, DNA condenses to form chromosomes . In the second step, ✔ Each pair of chromosomes lines up in the center of the cell . In the third step, . In the final step of meiosis I, .
Answer:
Prophase I, metaphase I, anaphase I and telophase I.
Explanation:
Prophase I is the phase of meiosis I in which DNA condenses to form chromosomes whereas in metaphase I, each pair of chromosomes lines up in the center of the cell. In anaphase I, each pair of chromosomes is separated from one another which is pulled by the spindle to opposite poles of the cell. In telophase I, the duplicated genetic material is separated that leads to two identical daughter cells.
How do autotrophs and heterotrophs benefit one another within an ecosystem?
A. Autotrophs produce oxygen and carbon dioxide for heterotrophs, which produce chemical energy for autotrophs.
B. Autotrophs synthesize ATP and other nutrients for heterotrophs, which produce oxygen for autotrophs.
C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
D. Autotrophs transform chemical energy into radiant energy for heterotrophs, which fix carbon for autotrophs.
Answer: The answer is A,
Explanation:
Answer:
C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
Explanation:
Autotrophs are organisms that conduct photosynthesis. One of the products of photosynthesis is oxygen, which is released into the air. Heterotrophs then take in this oxygen and give out carbon, which then the plants take in and use. This cycle goes endlessly on and on.

The strangler fig is a vine that starts out as a seed in the tree canopy of the rain forest. It drops its roots down from the canopy to the forest floor. By sprouting in the rain-forest canopy, the strangler fig seedling is exposed to more-
The strangler fig plant shows an aggressive growth habit as an adaptation that allowed its growth. It drops to the forest floor and develops its seeds by exposure to sunlight. Thus, option A is correct.
What are adaptations?Adaptations are a crucial part of the evolutionary process that allows the organism to fit and survive in altered environmental conditions. It has been due to the process of natural selection that gets inherited.
The aggressive growth habit of the strangler fig vine is to ensure its survival in the rainforest covered in canopies. The seed of the plants uses sunlight and nutrients to grow at a faster rate and hangs their roots on the first floor. The sunlight increases its rate of germination.
Therefore, option A. sunlight is used for germinating the fig seeds.

Answer:
jjejwjejejjeejejjdj
Cellulase enzyme is needed for the breakdown of cellulose molecule.
The bacteria present in the digestive system of cow produces cellulase which is a very important enzyme responsible for the breakdown of cellulose. This cellulase enzyme attached to the cellulose molecules and speed up the breakdown which results in the production of glucose molecules.
This glucose is further used by the cell for the generation of energy which is used in different activities. Glucose is the monomer from which cellulose is formed. The cellulase enzyme detached from the cellulose molecule after the completion of the chemical reaction so we can conclude that cellulase enzyme is needed for the breakdown of cellulose molecule.

serves as a minor reflex center
B)
conducts motor information from the brain to various
effectors
C)
processes sensory inputs and initiates appropriate motor outputs
D)
conducts sensory information from the peripheral nervous system to the
brain
Answer:
c)
Explanation:
The central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.
What is the central nervous system?The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.
It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.
Thus, the central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.
