how can toxic chemicals affect human immune, nervous, and endocrine systems?
Answer:Some toxic chemicals can make the body shut down and not function properly.
Explanation: Some gasses alter your cellular membrane like carbon monoxide or cyanide which affects your brain functions
Answer:
The toxins reduce the amount of cells which are capable of suppressing the immune response. So multi-resistant strains, which produce very high levels of enterotoxin, becomes even more dangerous.
For endocrine system the chemicals are linked with developmental, reproductive, brain, immune, etc...

eye color trait is a trait determined by polygenic inheritance explain whether using a pedigree chart would work to trace this trait in family
Answer:
Yes
Explanation:
The pedigree chart would go as far back as it is needed to which would show who has a certain eye color and who would get a certain trait.
Eye color trait is a trait determined by polygenic inheritance using a pedigree chart would work to trace this trait in family.
What is pedigree chart?A pedigree chart is a diagram that depicts the occurrence and appearance of phenotypes of a specific gene or organism and its ancestors from generation to generation, most commonly in humans, show dogs, and race horses.
Pedigree analysis is used to determine whether the inheritance mode is recessive, dominant, partial dominant, autosomal, or mitochondrial.
Furthermore, it determines the likelihood of an individual or offspring being affected in the given cross.
We can determine genotypes, identify phenotypes, and predict how a trait will be passed down in the future by analyzing a pedigree.
A pedigree's information can be used to determine how certain alleles are inherited: whether they are dominant, recessive, or autosomal.
Thus, it is sure that using a pedigree chart would work to trace this trait in family.

In an oil spill, why does the oil not mix with the sea water
Which of the following statements is INCORRECT?
a. The most common way to determine the size of a population is to count or estimate the number of individuals in a number of samples.
b. A transect consists of a long triangle and a line of a certain length. The occurrence of any individual within a certain distance of the line is recorded.
c. Ecologists tend to use quadrats to sample a stationary population.
d. The density of a population is determined by determining the size of the quadrat and then dividing this by the average number of individuals in the quadrat.
Answer:
I think A. is the right answer.
Explanation:
I searched up on how to determine population size and here here are some things I found. ¨The number of individuals in a specific area¨, ¨The most obvious way to determine the size of a population is to count, one by one.¨, but one thing I´m kinda sure is right is this one. It´s determining population size. ¨Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies¨ But just see for yourself.

In the Galapagos Islands, Charles Darwin found many different species of finches (a type of bird) that seemed closely related. He proposed that the birds had all evolved from a common ancestor. Match the bird beaks below to the most likely food source. Explain in the chart below how the five finches pictured above most likely came to have different beaks than each other and the extinct finch.
Answer: the beaks of the finches are adapted to the way the bird usually gets food. :) good luck!

Ben wants to know how a toy car's initial speed affects the distance that it is able to travel before it is stopped by friction, so he sets up the following experiment. In Ben's experiment, he places a toy car on a smooth, flat surface. Then, Ben applies varying amounts of force to the back of the car and measures the car's initial speed using a radar gun. The toy car is allowed to decelerate on its own until it stops. Finally, Ben measures the total distance that the car traveled. What is the outcome variable (dependent variable) in Ben's experiment?
A. the initial speed of the toy car
B. the friction between the car and the surface
C. the total distance that the car traveled
D. the type of car that was used
Answer:
the total distance that the car traveled
Explanation:
Answer:

Explain how science uses fossil evidence to support the theory of evolution.
Answer:
A: LAYER
Explanation:
simple i took the test
Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms are in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

Which of the following biomolecules is best represented by this formula?
A.
nucleic acid
B.
protein
C.
carbohydrate
D.
lipid
Answer:
The correct answer is option D. "lipid".
Explanation:
Lipids, known also as fats or oils, are organic compounds that are insoluble in water and are made up of carbon, hydrogen, and oxygen. The formula of this question shows a biomolecule that is made up of this three atoms, and even though carbohydrate are made up of this three atoms as well, we can determine that it belongs to a lipid because it contains many more hydrogen atoms than oxygen atoms. Other characteristic of lipids is their long chains of carbon and hydrogen atoms, which are represented by the lines shown in blue. I attached the missing formula.
Answer:
it is carbohydrate

Folded mountains form only at divergent plate boundaries, whereas shield volcanoes form only at convergent plate boundaries.
Folded mountains form only at convergent plate boundaries, whereas shield volcanoes form only at divergent plate boundaries.
Folded mountains form when hot, fluid rock rises through thin spots in Earth's crust, whereas shield volcanoes form when segments of Earth's crust are bent and doubled over.
Folded mountains form when segments of Earth's crust are bent and doubled over, whereas shield volcanoes form when hot, fluid rock rises through thin spots in Earth's crust.
Answer:
Folded mountains form when segments of Earth's crust are bent and doubled over, whereas shield volcanoes form when hot, fluid rock rises through thin spots in Earth's crust.
Explanation:
Folded mountain (Himalayas, Rockies, Alpha) refers to all the large mountains on planet earth.It is made up of sedimentary rocks.They are formed when two plates collide into each another, folding up:hence the name folded mountain.They are characterised with large granitic intrusion extending to many kilometers through the length, reaching the mountain edges.
This results from high magma supply rates ,which occurs during long term effusive eruptions.
They are recognised as broad, dome shaped structure, flowing downwards just like a shied used in battles,
