a group of students tested to see if the acidity of water affected pea plant growth
Answer:
I would say C because in number one, the tests were never repeated
Explanation:
do you mean
this question??
Experiment 1: A group of students tested to see if the acidity of water affected pea plant growth. The students followed a logical method and performed their experiment once, using control and experimental groups. Their results supported their hypothesis.
Experiment 2: A group of students tested to see if bacteria growth in water was affected by acidity. The students used control and experimental groups. They repeated their experiment several times and found the results were the same.
Which experiment most likely has greater reliability?
A. Number 1 because it follows a logical method
B. Number 2 because the experiment was repeated
C. Number 2 because the experiment was repeated and the results were always the same
D. Number 1 because it has control groups

which of the following best explains the purpose of photosynthesis?
In photosynthesis, oxygen is used to make sugar.
In photosynthesis, sunlight is used to make ATP
in photosynthesis, sunlight is used to make sure
in photosynthesis glucose is used to make energy
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

outward to form the universe.
Answer:
the answer is C
Explanation:
scientists believe that a ball of matter (the size of a pin head) exploded and created the universe! this is the big bang theory ♡

Explanation:
When DNA replicates, each strand of the original DNA molecule is used as a template for the synthesis of a second, complementary strand. Compare and contrast the replication of the two new strands, listing and explaining at least one similarity and one difference in the methods of synthesis.
Answer:
See the answer below
Explanation:
A typical double-stranded DNA consists of a leading and a lagging strand with 5' to 3' direction and 3' to 5' direction respectively. During replication, a RNA primer binds to each strand at the replication origin and DNA polymerase enzyme adds complementary nucleotides to the primer to elongate the new strand until the end of each strand is reached.
The replication process of the two strands are similar such that:
Both require RNA primer bindingBoth require DNA polymerase to add nucleotides in 5' to 3' directionThe replication of the two strands are different in a certain way:
The enzyme responsible for adding nucleotide bases to the growing DNA strand during replication can only add in 5' to 3' direction. Consequently, the leading strand is synthesized in a continuous manner while the lagging strand is synthesized discontinuously in short nucleotide sequences known as the Okazaki fragments. The fragments are later joined together by an enzyme known as DNA ligase.This means that the RNA primer only binds at a single location on the leading strand while multiple primers bind at multiple locations on the lagging strand. The replication of the twoWhat life process builds large complex substances from smaller, simpler substances?
A. Regulation
B. Growth
C. Synthesis
D. Excretion

Which discovery supported the endosymbiotic theory?
The discovery of independent DNA (from the host) in mitochondria and chloroplasts supports the endosymbiotic theory.
The endosymbiotic theory is the theory that mitochondria and chloroplasts, two important organelles found in eukaryotic cells, originated from bacteria that were engulfed by larger cells.
What is this theory?The presence of DNA in mitochondria and chloroplasts. Mitochondria and chloroplasts have their own DNA, which is separate from the DNA in the nucleus of the cell. This suggests that they were once independent organisms.
The similarity of mitochondrial and chloroplast DNA to bacterial DNA. The DNA in mitochondria and chloroplasts is similar to the DNA of bacteria. This suggests that they share a common ancestor.
The presence of ribosomes in mitochondria and chloroplasts. Mitochondria and chloroplasts have ribosomes, which are structures that are used to make proteins. Ribosomes are also found in bacteria.

explain how punnett squares predict the outcomes of heredity
Answer:
It is a tabular summary of every possible combination of one maternal allele with one paternal allele for each gene being studied in the cross. How are ratios and percentages alike? They both can be figured the same way.
Answer:
Punnett squares predict the outcomes of heredity because they show how parent alleles may be passed on to the offspring. It shows the different combinations to expect.

maple trees lose their leaves in fall. which part of carbon cycle comes next
On falling to the ground they mix with the soil with the help of bacteria. The carbon is released from the leaves in the air and is added to the carbon cycle.
What is the carbon cycle. ?The maple tree is a shrub that is commonly called maple. They are 132 species, that are native to Asia, appear in Europe, Africa and north and south America.
The carbon cycle is a process by which the carbon is returned back to the air and it continuously travels back to earth. After the fall the leaves fall down to the ground and re-merged to the soil as humus. The bacteria converts the energy that is again taken up by the plants.

how do waves affect landforms
the pressure and the force of waves produce more rocks
pressure and force of ways can break Cliffs Apart
waves can cause rocks to change it what it is made of
Answer:
Waves erode the bedrock along the coast largely by abrasion. The suspended sediment particles in waves, especially pebbles and larger rock debris, have much the same effect on a surface as sandpaper does. Waves have considerable force and so may break up bedrock simply by impact.
