Explanation:
From when we are very little, we are taught to know the difference between right and wrong and how to follow rules. As we get older, rather than the rules that we followed as children, we learn to follow laws that allow us to function as adults in today’s society.
We are all probably familiar with traffic laws or laws about stealing or committing crimes, but did you know that there are laws and public policies written specifically for and about families?
If you didn’t already know about these particular laws, now is your chance to find out!
For this activity, you will be researching the various laws and public policies related to families. In addition, you will be creating several scenarios where these laws might come into play.
Activity Guidelines:
You will start by researching various laws and public policies that pertain to families. You can really take this research in any direction that you like, while keeping in mind that the ultimate goal will be to write five short scenarios and connecting each one to a different family law or policy. For example, you could write a scenario that involves a parent who is intentionally hurting their child and connect this scenario to a child abuse law.
Each scenario description should be no more than about one paragraph in length. You are welcome to include dialogue in your scenario or simply summarize and explain your scenario idea. After each scenario, you will write the specific family law or policy being broken in the scenario or how it otherwise pertains to the scenario. The name of the law or policy and a brief explanation of its connection to the scenario is all that you need to include.
WILL MARK BRAINLY-IST
A basic template is included below. Feel free to use it or create your own in a word processing or slideshow program.
Your grade will be based on creating all five scenarios and your ability to connect each one to a different family law or policy. For further details on how you will be graded, see the rubric below.

explain what a species is and how resources lead to species biodiversity.
Species are organisms which have similar characteristics and are capable
of interbreeding. A common example is we human beings.
Resources leads to species biodiversity as a result of organisms moving
from one place to another in search of food for its survival. The availability
of resources will lead to an increase in reproduction and species
biodiversity as more organisms will be present in the area.
Scarcity of resources on the other hand results to lower species biodiversity
and decreased reproduction rate.

Active transport moves molecules from and to which concentration?
A: high to low
B: low to high
C: low to lower
Option (B) low to high is right Answer
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
We know that, Active transport moves ions and molecules across a membrane against the concentration gradient. It requires energy.
The characteristic features of active transport are:
-The movement of molecules in case of active transport is from lower concentration to higher concentration so it shows uphill transport.
-These have carrier proteins that are highly specific like enzymes for the substances to be carried across the membrane.
-The process of active transport can be inhibited by inhibitors that react with the protein side chains.
-The transport rate reaches its maximum when all the protein carriers are in use or get saturated with the substances to be carried.
The various types of processes that depend on active transport are:
-Absorption of amino acids from the gut.
-Absorption of mineral ions by plant roots.
-Excretion of urea and hydrogen ions by the mammalian kidney.
-Exchange of sodium and potassium ions in nerve cells.
-Filling of the contractile vacuole in amoeba.
The phloem in the leaves of a plant is rich in sugars because of the high rate of active transport.
Additional information :- Some intrinsic protein molecules function as molecular pumps. These permit the cell to go for active transport to accumulate glucose or ions against the concentration gradient. Cells that undergo active transport have abundant mitochondria that provide ATP needed to power active transport.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

How is the flow of energy within food webs interconnected with the cycling of
matter?
Answer:
Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat.

Which part of a cell is used by a virus to produce its protective protein coat?
A ribosome is the part of a cell is used by a virus to produce its protective
protein coat.
Virus produces a protective protein coat known as capsids which serves as
a means of protection for the organism. The capsids are produced through
the organelle known as ribosome.,
The ribosome acts as a site for protein synthesis in organisms and the
capsids being made up of protein means the ribosome was used to
produce its protective protein coat.

Explain the idea of Nature vs. Nurture in your own words.
Nature vs. Nurture both influence the observed traits of an organism.
The controversy between nature and nurture have been an ongoing discourse for many years. It is believed that the traits of an organism are dependent on genes inherited from the parents. Another school of thought believes that environment alone has the sole influence over the traits of an organism.
However, most scientists today are of the opinion that the influence of nature and nurture are intertwined and they both work together to influence the traits exhibited by any organism.

what does the author mean when she describes easter island as ""a destination with solitude built into its dna""?
A destiny with loneliness built into its DNA why, the DNA of the peoples of Easter Island is unique, there is a theory that suggests that long before Europeans discovered the island (in 1722), it served as a meeting place for the Polynesian people and Native Americans. Thus, the Rapa Nui would have in their DNA a mixture of these peoples. That theory was driven by an article published in 2014 that showed that today's Rapa Nui have 8% Native American DNA in their genome.
The why of solitary DNA
The Rapanui, who populated Easter Island,
Had no contact with the Native Americans until the arrival of the Europeans. Or if they did, it left no trace in their genes. That's what a study that analyzed ancient DNA of the island's inhabitants claims.These results call into question previous research that claims that there was contact and that it may have occurred several centuries earlier.
This is the first time Rapa Nui's ancestral DNA has been sequenced. It's the result? None of the five samples showed DNA from Native American ancestors.
What is right so far? It doesn't seem like much... the mysteries of Easter Island continue...
In this way, the author wanted to say that the DNA of the peoples of Easter Island is unique.

Why do you have to determine the total magnification when observing a specimen under the compound microscope?
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.

To test a new drug that has the potential of curing people of the common
cold a company asked human volunteers who were coughing and sneezing
to participate in a clinical study. The objective of the experiment was to test
whether the new drug could cure the volunteers in the experimental group of
the common cold. But instead of two groups, these volunteers were randomly
divided into three groups and treated as follows:
Group
Experimental
Group
Yes
Control
Group 1
NO
Control
Group 2
No
New ONS
Orange
Bedre
Yes
No
Yes
Yes
Which of the following is the best explanation of why a second control group
was included in this experiment?
O A To prove that the common cold cannot be cured
B. To provide the volunteers in the study with something to drink
O C. To help researchers conclude that results are related to the new
drug and not to the orange juice
O D. To confuse anyone who is trying to steal their new drug and sell it
as their own invention
Answer: C
Explanation: A good experiment does everything it can to eliminate confounding, or the influence of external sources on the data being measured. Orange juice could be a factor that plays a role in curing the symptoms, so provide a group with and without orange juice gives you the ability to show that the influence of orange juices didn’t have an effect on the cold, or did, but it gives you a baseline to show the effects of the medicine with and without orange juices.
