The two characteristics that distinguish primates from mammals are specialized behavior and unspecialized structure.
Primates are characterized by opposable thumbs, forward-facing eyes, and a low sense of smell. Primates have opposable thumbs because they adapted to tree living. All common ancestors of primates have opposable thumbs.
Primates have larger brains (in proportion to their body weight) than other mammals. They also rely more on visual perception at the cost of olfactory perception (which is the primary sense of smell in most mammals).
These characteristics are more prominent in monkeys, and much less so in Loris and Lemurs.

Which of the following best describes a feature of the Kingdom Animalia that differentiates it from Fungi? Animalia have cell walls and Fungi do not. Animalia are heterotrophs and Fungi are not. Animalia are eukaryotes and Fungi are not. Animalia have complex organ systems and Fungi do not.
Animalia has complex organ systems and Fungi do not.
Fungi are heterotrophic organisms with a chitinous cell wall. The fungal frame is fabricated from thread-like lengthy systems referred to as hyphae. Many hyphae collectively make an entangled shape referred to as mycelium.
Hence, fungi showcase the tissue stage of frame organization animals are heterotrophic organisms and do not use a cell wall around their cells. They showcase the organ machine stage of frame organization, this is to say, that they have got numerous organ structures of their frame to carry out distinct functions.

Explanation:
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.

What is the main component of the thin filaments in muscle fibers and is responsible for muscle contraction? actin myosin atp dna
The main component of the thin filaments in muscle fibres that is responsible for muscle contraction is Actin.
What are actin and myosin filament and how they are responsible for muscle contraction?Actin and Myosin both are proteins that are found in muscle tissue. Myosin protein is the thick filaments whereas actin protein is the thin filaments that work together to generate muscle contraction and movement.
Along with the actin, there are some other proteins such as troponin and tropomyosin that forms the thin filament. However, actin plays an important role in the contraction of muscles as each actin molecule consists of a single myosin-binding site.
All actin molecules join together to form a chain twisted into a helix configuration which is important for the contraction mechanism in muscles.
However, actin is the thin filament that plays an important role in the contraction of muscles.

How do muscles generally create movement
A) constant contraction of muscle groups
B)constant relaxation of muscle groups
C)Uncoordinated contraction and relaxation of muscle groups
D)Coordinated contraction and relaxation of muscle groups
Answer:
D) Coordinated contraction and relaxation of muscle groups
Explanation:
In order for muscles to properly work, the muscle groups have to contract and then relax in coordination.
If muscles were to constantly contract, then the muscles would get overworked and fail to function correctly.
If muscles were to constantly relax, then the muscles wouldn't be able to work at all.
If the contraction and relaxation of muscle groups were uncoordinated, then the organism wouldn't be able to have muscle control, which is needed.
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.
