A scientist wants to determine whether a certain type of yeast is able to perform anaerobic respiration. Describe a test the scientist could perform to see if the organism is capable of this.
Answer:
Follow these steps if you are unsure of the freshness of your yeast (or just want to give it a ‘good start’). See a How-to video of this test. Using a one-cup liquid measuring cup, dissolve 1 teaspoon of granulated sugar in 1/2 cup warm tap water at 110°F-115°F. Using a thermometer is the most accurate way to determine the correct liquid ...

Answer:
He could lock the plant in a room with no oxygen at all, if it survives it's anaerobic, if it doesn't then it's aerobic.
Explanation:
An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if free oxygen is present.

Use the library and other reference materials to research lupus. Then, write a 400-word report on what you have learned. Be sure to include symptoms, causes, and treatments.
Answer:
The one I chose is very interesting I think you will enjoy it.
Lupus is a multisystem disease in which autoantibody production can lead to inflammation and tissue
damage in any part of the body. The pathogenesis of lupus is thought to be a combination of
predisposing genetic factors and environmental factors such as medication, or infectious agents that
trigger an abnormal immune response. This occurs when Suppressor T cells fail to suppress, in other words there are defects in cell signaling

Answer:
[See Below]
Explanation:
A gene in DNA that codes for a trait or a characteristic.
Different versions of that gene are called alleles.
For example, a gene in DNA codes for a person's eye color, but the alleles depend on how they appear.
Brown and blue eyes would be alleles for a gene that codes for eye color.

which of the following best describes Mendel's idea of segregation?
A. Male offspring receive traits only from the male parent.
B. Female offspring receive only form the male parent.
C. Each parent has two copies of each gene and passes on only one copy to its offspring.
D. Each parent has one copy of each gene. each offspring receives half of its genes from each parent.
Answer:
C
Explanation:
Since we know about mitosis and sexual reproduction, each parent passes on only one copy of the gene because they got a copy of a gene from each of their parent before, and the new child will end up with two genes, one from each parent.
How dose the process of photosynthesis create food
Answer:
Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.

of a cloud.
C. Electrons flow from an outlet into a toaster, causing it to heat a
slice of bread.
D. A person rubs a shoe on a rug, causing extra electrons to be
transferred to the shoe.
Answer:
The correct example of current electricity is C. Electrons flow from an outlet into a toaster, causing it to heat a slice of bread.
Explanation:
Current electricity refers to the flux of charged particles through a conductor material per unit of time. In general, when we refer to electric current we are talking about the electron flux. Electric energy originates from the difference of electrical potential between two points when they get in contact through a conductor. This contact provokes an electrical current that consists of the transmission of negative charges called electrons through conductor materials such as metals from the source of generation to the point of consumption.
In the exposed example, the source of electrons is the outlet, while the point of electron consumption is the toaster. In this last artifact, electrical energy is transformed into heat to toast the bread.

The four types of most important organic molecules to structure and function are carbohydrates, lipids, proteins, and nucleotides for many organisms including humans.
Proteins are
biological organic molecules that are the most essential and versatile of all the organic molecules.it forms many cellular structures and molecules and performs various functions within the cell of organisms.They form tissues and muscles, speed up chemical reactions as enzymes, and perform many other cellular functions.Proteins are made up of amino acids form by nucleic acids that include DNA and RNA.

4. Discuss the sense organs of cnidarians
Answer:
To tell the truth I don't know what none of this stuff so I searched it up.
Explanation:
Cnidarian sense organs are thought to be exclusive to the medusa, a point we dispute subsequently. Nevertheless, the sense organs of the medusa are highly developed and distributed across Scyphozoa, Hydrozoa, and Cubazoa. In those hydrozoans with a medusa stage, many have eyes associated with the tentacle base.
Hope that is what you are looking for.
Answer:
he rhopalium, the sense organ bearing structure of Scyphozoa, as well as the Cubozoa (a modified group within the scyphozoans), contains the statocyst and eyes. It is borne on the margin of the bell in the medusa. The rhopalia of cubozoan medusae contain eyes with lenses, the most dramatic of cnidarian sense organs.

Atoms of carbon-14 are radioactive. They decay into atoms of the element nitrogen. Suppose that a sample of rock is taken from a fossil. The sample has 500 atoms of carbon-14 and 1500 atoms of nitrogen. If carbon-14 has a half-life of 5700 years, how old is the fossil? 5700 years old 11,400 years old 17,100 years old 2850 years old
Answer:
11,400 years old
Explanation:
The total number of atoms present at the beginning = number of C-14 + number of N-14 atoms.
Hence;
1500 + 500 = 2000 atoms = No
At time t, N = 500 atoms of C-14 remains
Since the half life of C-14 (t1/2) = 5700 years
N/No = (1/2)^t/t1/2
500/2000 = (1/2)^t/5700
1/4 = (1/2)^t/5700
(1/2)^2 =(1/2)^t/5700
2 = t/5700
t = 2 * 5700
t = 11,400 years old

Which of the following does not describe hormones in the body? I’ll mark the correct answer a brainliest
A. they are mediator molecules released in one part of the body but regulating the activity of cells in other parts of the body
B. most hormones enter interstitial fluid and then the bloodstream
C. hormones acts on muscles and glands only
D. hormones exert their effects by binding to receptors on or in the "target" cells
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
If an organism has a diploid number of 50, and one of its cells undergoes meiosis, what is
the number of daughter cells and how many chromosomes will each one have?
Answer:
for me
Explanation:
it's 25
because di is 2 and ha is 1
If an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.
What is Diploid?Diploid may be defined as a condition that determines the existence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.
On contrary, haploid cells generally contain only a single set of chromosomes. These types of cells are formed due to the process of meiosis, while diploid cells are formed by the activity of mitosis.
According to the question, if a diploid number of an organism = 50.
This means that 2n = 50,
n = 25.
As we all know that when a cell undergoes meiosis, it will definitely have half the amount of genetic content in its daughter cells.
Therefore, if an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.
