A pair of identical twins develop leukemias, where immature white blood cells proliferate uncontrollably. In each case, the cancer cells analyzed from identical twins displayed an identical chromosomal mutation and this critical mutation was not found in the twins normal cells. The twins developed leukemia at different times in their lives. What is the best explanation for the origin of this chromosomal mutation
Answer:
The chromosomal rearrangement resulted from a rare somatic mutational event that occurred in utero
Explanation:
Leukemia is a progressive type of cancer where immature white blood cells (leukocytes) proliferate uncontrollably. Next-generation sequencing (NGS) technologies have shown that somatic mutations are relatively common in different types of leukemia such as, for example, acute myeloid leukemia (AML). Moreover, identical twins are developed from one fertilized egg (ovum) that splits and develops into two identical individuals that share all of their genes (i.e., they have exactly the same genetic information). In this case, it is expected that leukemogenesis was initiated in the utero by the occurrence of a chromosomal rearrangement and proceeded early during development as distinct clonalities. In addition, the fact that identical twins developed leukemia at different times in their lives also indicates that this malignancy wasn't caused by only one mutation, but instead it was triggered by multiple mutational events (i.e., leukemia is a multistep cancer caused by secondary genetic changes).

Why is it more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain?
the trophic pyramid is the reason
what the trophic pyramid is: Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers
- predators get little energy from the prey they eat so they must consume multiple prey
It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.
The trophic levels of food chainThe food chain is defined as a feeding pathway that consists of similar organisms that are placed in the same trophic levels.
Trophic levels in a food chain are those levels that is occupied by a group of organisms that have a similar feeding mode.
The plants which are the producers are at the lower trophic level while the carnivores are at the higher trophic levels.
The carnivores eats meat from other animals but not plant or plant products which obtain direct energy from sunlight.
Therefore, It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

identify two other physical factors and explain their effect on the organism living in the lake?
Answer:
The correct answer is - light level and temperature.
Explanation:
The structure and function of lakes are determined by various factors such as temperature, light level, wind turbulence, water flow rate, dissolved oxygen, acidity (pH), salinity, habitat size, hydrology, and water depth. Stratification and water circulations are influenced by temperature and wind turbulence.
Light level is an important abiotic factor in lake ecosystems. Light is an essential part for plants to perform photosynthesis. Light can directly affect how much life you find in a given area depends on the production of energy and food by the aquatic plants by photosynthesis.
Temperature is a similarly important factor for lakes or other aquatic organisms as it is for land animals. each organism is able to survive in specific temperature ranges and their metabolic activity also depends on the specific temperature range.

Which statement best describes the relationship between protein, amino acids, and DNA? (1 point)
O DNA codes for proteins. Proteins are made up of amino acids.
O Amino acids code for DNA. DNA is made up of protein.
O DNA codes for amino acids Amino acids are made up of proteins.
O Amino acids code for protein. Protein is made up of DNA.
Answer:
Explanation:
The major relationship between protein and nucleic acid is the reproduction of DNA which contains the information on how cells are used together with RNA which helps to make protein. Both nucleic acid and protein they have four biomolecules which are common in both of them.
Short answer: Using a binary code, genes (DNA) specify how proteins (among other things) are to be synthesized.
Analogy: If DNA is a cooking book, genes are recipes, and proteins the dishes resulting from processing the recipe ingredients.
The relationship between protein, amino acids, and DNA is defined by the DNA codes for proteins. Proteins are made up of amino acids.As DNA codes for proteins.
DNA, RNA, and protein are all intently related. DNA carries the records vital for encoding proteins, even though it does now no longer produce proteins directly. RNA includes the records from the DNA and transforms that records into proteins that carry out maximum cell functions.
What is DNA function?The essential process of DNA is to make the proteins that residing matters want to grow.

what describes skeletal muscles
"Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."
