Elodea is a plant that lives in water. Like all plants, elodea can make its own food through
process called photosynthesis. Oxygen gas is also produced during photosynthesis.
Photosynthesis can only happen in the presence of light. To measure the rate of
photosynthesis, a piece of elodea can be placed in an inverted test tube filled with a
sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the
top of the test tube.
A student has designed an experiment using elodea plants. The experimental setup is
shown in Figure 1-4
Which of the setups would serve as the control of the experiment?
Bucket
Lamp
Flashlight High
Natural
Elodea
Sodium
bicarbonate
solution
The controlled variable is kept constant during the whole experiment in all the different study groups. In this experiment, Sodium bicarbonate solution is the controlled variable.
------------------------
During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In this experiment,
The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variable → Sodium bicarbonate solution. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.-----------------------

Genetic variation is more commonly found in sexually reproducing organisms, as compared to asexually reproducing organisms, because
1 point
in asexual reproduction gametes fuse to lead to new genetic combinations
in sexual reproduction the gametes formed are all genetically identical
in asexual reproduction the gametes formed are genetically different
in sexual reproduction gametes fuse to lead to new genetic combinations
Answer:
In sexual reproduction gametes fuse to lead to new genetic combinations
Explanation:
In sexually reproducing organisms, there are two parents who create genetically diverse offspring.
This occurs because the gametes of the two parents combine to create very unique genetic combinations, which lead to increased genetic variation.
On the other hand, asexually reproducing organisms reproduce without a partner.
Their offspring are identical clones to the parent, so they have much less genetic variation.
So, the correct answer is that In sexual reproduction gametes fuse to lead to new genetic combinations.

According to https://open.oregonstate.education/aandp/chapter/13-1-sensory-receptors/
- "A major role of sensory receptors is to help us learn about the environment around us, or about the state of our internal environment. Different types of stimuli from varying sources are received and changed into the electrochemical signals of the nervous system. This process is called sensory transduction."

The muscle that originates on the sacrum and transverse process of each vertebra and inserts on the spinous process of the third or fourth more superior vertebra is the ________ muscle. Group of answer choices quadratus lumborum interspinalis semispinalis
Answer:
multifidus muscle
Explanation:
Multifidus is a group of smaller muscles located near the spine (anteriorly among cervical paraspinal muscles) that extend, flex and rotate the spine. This muscle (multifidus) is an important stabilizer of the spine by stabilizing the joints at each segmental level. The multifidus muscle controls the erection of the spine and stabilization during its movements and the movement of the extremities.

A particular pea plant has one allele for a tall stem (T) and one allele for a short stem (t). By observing it, you can see that it has a tall stem as well as many other different traits. Using this example, explain the difference between phenotype and genotype. Which one can be observed? Which one helps to determine the other?
Answer:
phenotype is the physical make up of an organism. it is controlled by alleles found in the cells of an organism. dominant alleles overshadow the recessive alleles. the allele for tallness for example, is dominant to that for shortness. since alleles occur in pairs, this plant which is tall can either be genotype TT or Tt , two dominant alleles or one dominant allele and the recessive allele which overpowers the recessive allele hence making the plant appear tall. genotype is the genetic make up of an organism. this determines how an organism appears to look externally.
hence genotype determines phenotype.

Group of answer choices
protein.
nucleic acid.
retinal.
carbohydrate.
When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.
What are Nucleotides?Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:
A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.
Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.

A projectile is fired vertically upward at an initial velocity of 100 m/s. How high will it rise? How long will it take to reach that height?
The question is solved using the equations of motion
According to the equations of motion:
[tex]v^2 = u^2 -2gh[/tex]
v = final velocity
u = initial velocity
g = acceleration due to gravity
h = height
Note that at the maximum height, the final velocity (v) = 0 m/s
so we can write:
[tex]u^2 = 2gh[/tex]
[tex]h = \frac{u^2}{2gh}[/tex][tex]h= \frac{100^2}{2 * 10}[/tex]
h = 500 m
The time taken is obtained from:
[tex]v= u - gt[/tex]
since v= 0 at maximum height
[tex]u = gt\\\\t= u/g\\\\t= 100/10\\t = 10 s[/tex]
