Hello!
The answer is D, The U.S Public Health Service Policy. Its main purpose was providing protection for human subjects for research work which was conducted by federal agencies. You can read more about it on HHS.gov, as it is a very interesting regulation.
I hope this helps! :)
Issued in 1974, 45 CFR 46 raised to regulatory status US Public Health Service Policy. Option D
What is the regulatory status?The restrictions known as the Common Rule for the protection of human subjects in research done by or supported by federal agencies are outlined in Title 45 of the Code of Federal restrictions, Part 46. These laws define moral principles and requirements for the protection of research subjects who are being used as human subjects.
The US Public Health Service (PHS) published the policy that would eventually become 45 CFR 46 in 1974. This policy established standards for the examination and approval of research involving human subjects as well as the legal foundation for the protection of those individuals. Informed consent, weighing risks and benefits, and the creation of Institutional Review Boards (IRBs) to regulate research techniques were all adopted.

Can you use evidence of evolution found in individuals of a population?
Answer:
Individual organisms don't evolve. Populations evolve.
Explanation:
Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions

The diagram shows an ocean food web. Which organism is a primary consumer? krill elephant seal Killer whale Elephant seal O squid O penguin Penguin Leopard seal Squid Cod Krill Zooplankton Phytoplankton
Answer:
Krill
Explanation:
If you look at the diagram for this assignment, you can see the main organism that produces its own food is the phytoplankton. The animal that eats that organism is called a primary consumer. So, if you were to follow the arrow from the phytoplankton (or the producer), it would lead you to the zooplankton, krill, and cod. Since there are only one of these primary consumers as the choices, you would pick the only one available for the multiple choice, which would be krill :D
Answer:
A. krill
Explanation:
None of the other organisms are primary consumers.
Describe the rock layers shown in Diagram A and any forces acting on the rock.
The rock in diagram A has three horizons and no force acts on it.
What is a rock?A rock is a geological term that refers to solid materials, made up of crystals or grains of one or more minerals. Rock is the main material in the Earth's crust.
Four diagrams of the Earth's crust are shown in the image. All four have three horizons and different forces influence them except A. These forces are caused by the movements of the Earth's lithosphere and are represented by arrows in the direction of movement.
In the case of diagram A, having no arrow means that no force acts on it. Additionally, you can see the three horizons or layers that make up this sample of land.

describe why rocks found at the bottom of the river are smooth and flat.Please in your own words,My teacher would get mad
The rocks found at the bottom of a river smooth and flat because those are collides with each other.
Explanation:
At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.
This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.
Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.
What is Abrasion?Abrasion is the process of rubbing or scraping away a material, by rubbing against a rough surface or causing friction. This type of mechanical weathering can be brought about by a variety of things, including wind, water, snow, and human action. Rock, metal, plastic and wood are some of the materials that may be subject to abrasion.
This may result in material loss and modification of the appearance and texture of the surface. Natural features such as the smoothness of river boulders or the roundness of pebbles on a beach can also be the result of friction. Sandblasting, grinding and polishing are some examples of industrial abrasive applications.
Therefore, Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

If an invasive species emigrated from a continent to a small island near the continent, what would most likely occur on the island
Answer:
Organisms on the island would migrate to a larger island.
Invasive species can cause extinctions, reduce biodiversity, compete for resources, and modify environments.
What is an invasive species?An invasive species is a category of non-native species that has overtaken the habitat to which it was initially introduced.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Preventative measures are the most practical and secure method of managing invasive species. It is far more effective to deal with invasive species early on and quickly than to try and contain an extensive infestation. The invasive species may be the target of control and management measures if eradication is not achievable.

If each parent has two sets of genes and chromosomes why do their offspring receive only one set from each parent
Answer:
Because we are diploid humans, and we have 2 chromosomes per set. We get one set from our mother, and one from out father. Each of the sets from our parents are haploid (1 ), so together they are a diploid(2) set. I can go into depth more with meiosis if you need.

Which of the following is a correct association?
Answer:
The first one
Explanation:
because it has the most words on their.
The correct association is option a.The cell synthesises proteins and organelles in the G2 phase (also known as the "Gap 2 phase") of the cell cycle in order to prepare for cell division.
The cell enters the G2 phase following DNA replication, which takes place during the S phase. In order to manufacture the elements required for cell division, the cell continues to expand and goes through further protein synthesis during this phase. These proteins play a role in the development of the mitotic spindle, control of cell cycle checkpoints, and cytoskeleton organisation.
The cell also creates organelles like the mitochondria and endoplasmic reticulum to make sure there will be enough energy and cellular building blocks for the impending division in the phase.

What are the types of energy ?The energy can be defined as ability to work or produce action and / or movement and manifests itself in many different ways, such as body movement, heat, electricity, etc.
The different types of energy include Kinetic energy which is associated with the movement of bodies. Potential energy which is stored by virtue of a body's position relative to its surface is also called gravitational potential energy.
Thermal Energy or Heat can be defined as the energy associated with the kinetic energy of the molecules that make up an element, it can be manifested if there is a temperature difference between two bodies.
Chemical energy released or formed from chemical reactions, Solar energy from sunlight. This form of energy is used to generate electricity through photovoltaic plates, for example.

How does myelin increase the speed of the action potential?
It insulates the axon and assembles specialized molecular structure at the nodes of Ranvier. In unmyelinated axons, the action potential travels continuously along the axons.
For example, in unmyelinated C fibers that conduct pain or temperature (0.4–1.2 μm in diameter), conduction velocity along the axon is 0.5–2.0 m/s (as fast as you walk or jog).

The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
Synthetic theory of Evolution The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.
