b) they can contaminate bodies of water
c) they can contain contaminants that can enter the air during storms or high winds
d) fertilizer use does not impact respiratory health
Answer: C) They can contain contaminants that can enter the air during storms or high winds.
Explanation: A is wrong because I got it wrong (Sorry, can't give much explanation there).
B is wrong because water contamination does not directly relate to respiratory health.
D is wrong because fertilizers can impact respiratory health (Explanation seems lack-luster, but I feel like this is common sense).
Hope this helps :)

Explanation:
They can contain contaminants that can enter the air during storms or high winds.
In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.

100 meters
200 meters
300 meters
Answer: 100 meters
Explanation:
The thermocline begins at 100 meters of depth. Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth. From the given graph it cam be seen that at 100 meters the thermocline begins such that the temperature drops from to.

Describe the ways mutations can affect DNA and chromosomes.
The mutation affects DNA and chromosomes by changes in the sequence of DNA or changes in the gene present on the chromosome.
What is mutation?The mutation is a sudden change in the structure of chromosomes or DNA. The smaller mutation affects the nucleotide base in DNA, while the larger mutation affects the genes present on the chromosomes.
The substance which causes mutation is known as mutagens. Mutation can cause problems in growth and development and affects the functioning of the body. When changes occur in chromosomes or DNA, they cause changes in the protein. Due to this, a different kind of protein is produced.
The mutation is caused by the insertion, duplication, deletion, and substitutions of a DNA sequence. Thus, mutation can affect DNA and chromosome in many ways.

You want to determine what vehicle will get you to school in the fastest amount of time. Each day at 6:30am, you drive a different vehicle: a Ferrari, a
Nissan 350ZX, a Mazda RX8, and a Neon SRT4. Your results state that the Ferrari takes you the least time to get to school. The dependent variable in
this experimentis
A.the time that you leave each day (6:30am)
B.the type of vehicle
C.the time that it takes you to get to school
D.the route that you take each day
Answer:
The correct answer would be - option C. the time that it takes you to get to the school.
Explanation:
The dependent variable is the factor or variable in any research or experiment is the variable that depends on the independent variable which means it changes with the change in the independent variable.
Here the time the different vehicle takes to get to the school is a dependent variable as it depends on the fact that which vehicle is using and changes with the change in the type of vehicle.
I understand what earth outer layer is made of underneath the water and soil on the surface
Yes
Or
Not yet
Explain
The planet earth being a terrestrial planet is made up of rocks and hard rigid slabs of rocks called plates. These plates float on the flexible (asthenosphere) Mantel.
I understand that earth is a rocks planet and is made up of rocks and these rocks are called plates.
This uppermost layer or the crust of the lithosphere is composed of SIAL that is rocks made from aluminum and silicon, oxygen components. The layer lying below this is made from the semi-fluid matter called as upper mantel that is the asthenosphere which is partly molten and is said as molten rock. Due to the less dynamicity of this layer the above crust floats or drifts.Hence the water and soil in the lithosphere are characteristic of the crustal rocks.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

PLEASE HELP!!!!! Describe in detail the process of dna replication
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
