Analyzing Relationships Describe how environmental science helped the Trust decide that some dams should be removed.
Answer:Environmental servers build dams to keep water out of areas were animals safe.
Explanation:i just did this one and got it right!
Environmental science helped the trust decide that some dams should be removed dams reduces the complete ecological benefits that can be derived from the free-flowing rivers.
What are Dams?Dams may be defined as a type of barrier that is significantly constructed in order to hold back water and enhance its level that forms a reservoir that is utilized to generate electricity or as a water supply.
Environmental science believed that dams tend to synthesize numerous environmental impacts like alteration in wildlife patterns, destruction of wildlife habituation, interference with the natural flow of water, etc. Dams are also associated with the mechanism of ecological restoration and remarkably interfere with the natural characteristics of water and deteriorate it.
Therefore, environmental science fundamentally supports the trust decide that some dams should be removed.

Explain why parents and children don't look exactly alike by posting on the discussion board. Use the vocabulary words: chromosomes, DNA, inherited traits, and mutations in your explanation.
Answer:
Explanation:
Deoxyibonucliec acid(DNA) contains the genetic constituent of an individual for a child or an individual he inherits equal proportion of genetic make up or traits from both mother and father hence, the genetic constituent of a child is never 100% mother or 100% father but a blend of the two to give a new genetic makeup that have never existed before and cannot be entirely identical with either parents but 50% identical with each parent.
Mutation is a sudden change in genome of an organism that is heritable, mutation alters the genetic constituent making it different from the original plan hence, if mutation should occur an individual could have a look that is not identical with the parent because the physical expression is the function of the genetic make up.
Chromosome crossing over effect could also alter the make up of an individual making it different from parental gene.

If a bullet were to penetrate a lung, which three anterior thoracic body cavities would it enter, and which layer of the serous membrane would it encounter first?
Answer:
First of all is ventral: cavity that makes up the thoracic and abdominopelvic cavity ventral: cavity that makes up the thoracic and abdominopelvic cavity
Secondly it is thoracic: chest cavity
And thirdly it is pleural cavities: which consist of ths lung cavity
That is it will encounter tbe parietal layer of the serous membrane first :lines cavity
Explanation:
The organs in the body are safely guarded by the membrane, cavities and sheaths(which has different compartment). They act to protect the organs in the body like lungs.
A person who was shot with a gun, the bullet must pass the body cavities when moving to the lungs. It must first pass through the 3 cavities before it arrives at the lungs that is the ventral cavity, thoracic cavity and the pleural cavity. The serous membrane is usually found within the walls of the thoracic cavity.
If all your organs are components in the human body system, what body part act as the boundary?

What nutrients, or matter, must pass through the cytoplasm to reach the cell structures that make up a cell?
Answer:
The correct answer is - amino acid, sugars and fats molecules are major nutrients.
Explanation:
Cell nutrients come in numerous structures, including amino acids, sugars and fats. So as to provide energy to the cell and provide structures, these particles need to go over the cell membrane, which capacities as a barrier that can be pass through different means like endocytosis, diffusion, facilitated diffusion and many more.
plasma membrane is semi-permeable layer which allows specific molecules and substances to pass through the cell and make celular structure and provide energy.

Explanation:
Assume that you found an object that looks like a dead twig. You wonder if it might be a stick insect. How could you determine if it is a living thing?
Answer:
I determine if the object is a living thing by checking to see if it responds to the environment
Could determine if it is a living being by checking if it responds to stimuli
Living beings or organisms are all complex structures that are characterized by carrying out activities such as:
feeding.development.reproduction.interaction with other organisms.respond to the environment.Some of the most common classifications of living organisms are:
animals.plants.fungi.According to the above, to know if that object is a living organism the best option would be to activate stimuli in it such as vision, touch, smell, hearing, or taste to see if it has any reaction to these stimuli.
For example, you can touch the object and if it moves it shows a response and therefore it is alive.
According to the above, the correct answer is checking if it responds to stimuli

What can be concluded from the result? A. Both bacteria A and bacteria B cells are competent. B. Competence in bacteria A is constitutively expressed C. Competence in bacteria B is dependent on the phase of growth D. Neither bacteria A nor bacteria B cells are competence
Answer:
The correct option is C: "Competence in bacteria B is dependent on the phase of growth"
Explanation:
Since this set of cells produced fluorescent bacterial colonies, it means it took up the foreign strain of DNA and integrated in into its own plasmid. Since the other strain of cells was not able to present fluorescent bacterial colonies, something might have gone wrong or mishandled while preparing the competent cells.

What is physical change?Physical changes are changes which affecting the form of chemical substances but not it's chemical composition. Physical change are the processes in which we can separate mixture from compound, but can't usually be used to separate compound into chemical elements or simplest compound.
Physical change takes place when mixture are can't separate by chemical changes then we separate by the help of physical change. In general a physical change is reversible using Physical means.
A physical change involves a change in physical properties. Example- physical properties including melting, freezing, sublimation etc.

Why do ecosystems that are part of the same biome tend to be similar?
A major disturbance that almost caused a total collapse, but that the ecosystem was able to recover from eventually.
The provided question is incomplete, the correct question is attached with the answer:
Answer:
The correct answer is - the grasses which is diseased.
Explanation:
In the event that the grasses were diseased, the environment will recoup itself from this sort of disturbance. On the off chance that the number of inhabitants in snakes and hawks of prey increments so the biological system will recoup itself from this disturbance since snakes are the food of hawks.
So, if the number of inhabitants in snakes increments so more food is accessible for birds of prey as snakes and that is the reason populace of birds of prey likewise increments and the number of inhabitants in snakes is controlled.
An ecosystem is a system where an organism lives collectively and socialise with their surroundings. A robust ecosystem is necessary to keep the control nutrient cycle and food cycle.
A major disturbance from which the ecosystem overcame was when both the grasses and snakes got infected. The explanation for this is:
Increasing the number of snakes affected the size of the grass and decreased the number of rabbits as they were getting eaten by the snakes and hawks.Increasing the number of snakes also increased the number of their prey hawks.Increased hawks population controls the population of snakes and in this way, the biological food cycle will be maintained.Therefore, disease in grasses and snakes caused a major disturbance that almost caused a total collapse, but the ecosystem was able to recover.
