Genetically identical armadillos were kept in the same controlled environment from birth and provided the same diet. Even though the animals were genetically identical and shared the same mother, they showed variations in their phenotypes that were beyond the normal range in expression.
Based upon today’s knowledge of genetics, which explanation describes the most likely cause of the phenotypic variations?
Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.
MutationThis refers to a sudden change to the DNA sequence of living organisms.
When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.
For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.
In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.

A major environmental problem caused by using the agricultural practice of tilling is a compaction of soil from adding compost b intercropping by traditional farmers c eutrophication from excessive fertilizer use d ozone depletion from fossil fuel use
Compaction of soil is a major environmental problem caused by Tillage.
What is Tillage?Tillage refer to mechanical turning or manipulation of soil for the purpose of planting. it is done use tractors, harrow and plough.
Tillage lead to compaction of soil.
Compaction of soil occur when soil particles are pressed together or form clods which make it to have small pores or reduction of pore space thereby reducing infiltration of water and soil aeration.Therefore, Compaction of soil is a major environmental problem caused by Tillage.

Phloem delivers the sugar made during photosynthesis to various parts of a
plant. Some food energy is converted into ATP for uses during plant activities such
as phototropism. Which two plant systems are interacting in this scenario?
A:Transport and response.
B:Reproductive and transport.
C:Reproductive and response.
D:No plant systems are interacting.
The two systems in plants that are interacting when sugars are delivered to different parts and when plants respond to light would be transport and response.
Transportation and tropism in plantsSynthesized foods in the form of carbohydrates are transported from sources to sinks in plants through the phloem. This form parts of the material's transportation system in plants generally.
The transported foods are used to generate ATP during respiration. ATP is spent when plants respond to external stimuli such as water, light, objects, etc. Response to external stimuli in plants is known as tropism.

Gene flow, a mechanism of evolution, works in populations not separated by ______
Due to the antiparallel nature of the dna double helix, _________.
The antiparallel nature of the DNA double helix is responsible for the opposing direction of replication.
DNA replicationThe DNA is made up of two strands that are antiparallel to each other. One is in a 5' to 3' direction while the other is in a 3' to 5' direction.
The replication process can only proceed in 5' to 3' direction only.
Consequently, one strand at a replication fork is synthesized in the direction of the fork, while the other is synthesized in the opposite direction away from the fork.

Which two systems are most likely interacting when a person experiences itching caused by a skin irritant?
Answer:
circulatory and excretory
Explanation:
The two systems that are most likely to interact when a person feels itchy from a skin irritant are the nervous system and the immune system.
What is the physiological explanation of itching?
In general, itching is a signal sent by nerves from the skin to the brain after the immune system releases substances - such as histamine - in response to irritation.
With this information, we can conclude that the two systems that are most likely to interact when a person feels itchy from a skin irritant are the nervous system and the immune system.

Occurs when the radicle of the seed becomes the root, and the hypocotyl becomes the stem and the leaves
Answer:
Monocots, such as corn (right), have one cotyledon, called the scutellum; it channels nutrition to the growing embryo. Both monocot and dicot embryos have a plumule that forms the leaves, a hypocotyl that forms the stem, and a radicle that forms the root.
Which is an example of natural selection in action?
Answer:
the third one
Explanation:
The definition for natural selection is "the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution. Compare with survival of the fittest (see survival)."
The third question shows us natural selection. Because the population of black mice went up and the tan mice went down. this is an example of natural selection because the black mice have adapted to their environment and reproduced while the tan mice have not.

Which of the following organs does a dog not have? spleen appendix gallbladder large intestine.
Answer:
Surprisingly, dog don't have an Appendix
Explanation:
Does this help?
The cecum, a part of the large intestine, is attached to the appendix, which is a small, finger-like pouch. Dogs, along with many other animals, do not have an appendix, although humans do.
In humans, the appendix is thought to have some minor immune system activities and may help with digestion. It is a vestigial organ, meaning that it has lost or reduced its original role over evolution, and its specific function is not fully understood. Dogs do not have an appendix because their digestive systems have different adaptations. Dogs have a digestive system that is relatively short and designed to break down animal proteins.
Therefore, the correct option is B.
