Which impact of global warming has the greatest effect on drinking water supplies?
A.melting mountain glaciers
B.rising sea level
C.higher acid levels in the ocean
D.early spring blooming of flowers
Global warming is mainly caused by an increase in the temperature of atmosphere. The main impact of global warming has the greatest effect on drinking water supplies is melting mountain glaciers.
Which gas is responsible for global warming?The gases that leads to greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor, and fluorinated gases.
These gases increases the temperature of the atmosphere and results in global warming.
This leads to the melting of mountain glaciers which makes a great reduction in the availability of drinking water.
Thus, the correct option is A.

What is the reason water has so many special properties?
Answer: Water has many unusual properties
Explanation: Water has many unusual properties because of its polar covalent bonds. Oxygen has a larger electronegativity than hydrogen, so the electron pairs are pulled in closer to the oxygen atom, giving it a partial negative charge. Subsequently, both of the hydrogen atoms take on a partial positive charge.

Criminal profiling has some differences to
other forensic science methods. As you've
seen, there are differing opinions about the
use of scientific and non-scientific techniques
in forensic science. Considering what you've
learned, identify what is science, what clearly
is not science, and what resembles science
(but doesn't meet the criteria for science). For
each of these, make sure to give real world
examples and explain why it is either a
science, not science, or resembles science.
Answer:
Knowledge gain through observation and experimentation.
Explanation:
Science is the systematic study of the structure and behaviour of the physical and natural world through observation and experiment. That knowledge which can be gain through observation and experimentations is considered as scientific knowledge and those knowledge which can be attain through other sources not observation and experiments is known as non-scientific knowledge so we can say that observation and experiments provide scientific knowledge.
18. Brayden is trying to figure out how petal shape is determined in two different roses. In the pink
rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are
different from each other. How does this affect how many types of proteins there are in each petal
cell?
a
The pink rose has one type of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
b
The pink rose has one type of protein for the petal shape feature. The yellow rose has one
type of protein for the petal shape feature.
с
The pink rose has two types of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
d
It is impossible to say anything about proteins from the given information.
Answer:
c
Explanation:
they would have diffrent gene versions and protines to get their colors
In the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.
What is the petal shape dependent on?Generally, the characters are dependent on the genes that are present in the DNA; either the gene variants, such as the alleles, show pure dominance or they combine to produce the effect, and here the pink rose petal has the same alleles so they will express the single protein while the yellow has different alleles so it has the chance of the two proteins.
Hence, in the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

This genus of microbes breaks down dietary fibers and phytonutrients (like polyphenols) which have beneficial effects for your health. What's more, Lactobacillus even helps to feed other bacteria in your gut, such as the ones that produce butyrate (which the cells in your gut lining need for energy).

The diagram below shows the cell cycle. Which type of cell division is indicated by the processes happening in C and D?
Answer:
This process is mitosis
maybe this will help
It might not be exactly what you are looking for but this is what I have done
The type of cell division indicated by the processes happening in C and D would be mitosis.
Mitosis is the division of vegetative cells and results in the production of 2 genetically identical daughter cells.
During mitosis, sister chromatids separate into opposite poles and each group of chromatids forms the genetic materials for daughter cells that will become independent when the parent cell undergoes cytokinesis - the division of the cytoplasm.
C in the image represents the metaphase of mitosis where chromosomes align at the center of the cell and get engaged by spindle fibers. D represents the anaphase where sister chromatids have been pulled apart and begin to migrate to opposite poles through the contraction of spindle fibers.
After completing their migration to the poles, the chromatids decondense, and a nuclear envelope appears around each of them. The cytoplasm then divides into two for new independent daughter cells to be formed.

How do these equations explain why the total amount of O2 and CO2 remains the same?
Answer:
They cancel each other out. There are 12 Carbon molecules on each of the equation and 54 Oxygen on each side So their carbons cancel each other out on each side of the equations as the oxygen.
