Answer:
cc × cc
Explanation:
This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).
In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.
Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).

Which is the smallest division of geologic time?
O A. Eon
O B. Period
O C. Era
O D. Epoch
Answer: Epoch
Explanation: An epoch is the smallest unit of time on the scale, but still encompasses a period of millions of years. Chronologically, epochs are grouped together into larger units called periods. Periods are combined to make a subdivision called an era. An eon is the largest division of geological time.
The smallest division of geologic time is an epoch. Thus, the correct option is D.
What is an Epoch?The geologic time scale is a representation of the time based on the rock record of the Earth. It is a system of chronological dating which uses the process of relating strata to time and the scientific branch of geology that aims to determine the age of rocks.
An epoch or reference epoch is an instant in time which is chosen as the origin of a particular calendar era. The epoch serves as a reference point from which the time is measured.
An epoch is a division of the geologic period and it is the smallest division of geologic time which lasts for over several million years.
Therefore, the correct option is D.

Which of the following statements best describes the behavior of DNA during electrophoresis?
Longer DNA fragments migrate farther than shorter fragments
Migration distance is inversely proportional to the fragment size,
ОО
Uncut DNA migrates farther than DNA cut with restriction enzymes
O Positively charged DNA migrates more rapidly than negatively charged DNA.
Answer:
Migration distance is inversely proportional to the fragment size,
Explanation:
Gel electrophoresis is a technique used in molecular biology that uses electricity to separate biological molecules based on size (DNA) or charge (proteins). For the DNA molecule, different sizes are separated from one another based on how fast they can migrate through the gel matrix.
In this technique, small fragments or sizes of DNA migrates farther than long sizes of DNA due to low friction in the matrix. In other words, the smaller the size of the DNA fragment, the farther the migration distance and vice versa. This shows that an INVERSE RELATIONSHIP exists between the migration distance and the fragment size in the electrophoresis procedure.

a constant net forced of 150 N is exerted to accelerate a cart from rest to velocity of 45 m/s in 8 seconds.what is the mass of the cart?
Answer:
The mass of the cart is 26.7 kg.
Explanation:
To find this answer use the formula for acceleration first to find how fast the object had to be acccelerating to gain a velocity of 45m/s in 8 seconds flat.
Here's the formula for acceleration:
a = V- V₀ ÷ T (Wher V = final velocity; V₀ = Initial velocity, and T = time)
Plug all known values into the equation and you get -
a = (45m/s - 0m/s) ÷ 8 , which works out to 5.625 m/s²
Once you have this value then you place it into the equation for finding an object's mass, and that formula is:
M = [tex]\frac{F}{a}[/tex] or M = [tex]\frac{150N}{5.625m/s^{2} }[/tex]
This works out to 26.6667 kg or approx. 26.7 kg if you are asked to round it to three significant figures.
which sensory receptors are involved in hearing
Answer:
The cochlea is filled with two fluids (endolymph and perilymph), and inside the cochlea is the sensory receptor, the Organ of Corti, which contains hair cells, or the nerve receptors for hearing.
Have a good day
Mechanoreceptors are involved in hearing, which transmits the signals from external stimuli through mechanical ion-gated channels.
What is the structure of the ear?The organ of the Corti on the basilar membrane has hair cells that are involved in the sensory mechanism for hearing.
In the inner ear, there are six receptors (cochlea, two otolith organs, and three semicircular canals) which make a transduction unit consisting of hair cells.
In these receptors, external stimuli transmit the signal through the mechanically gated channel, external stimuli are touch, pressure, and hearing.
This processed signal to the brain by the neurons to hear the sound, and all the signal accumulate through the primary sensory receptors which are hair cells in the ear.
Therefore, mechanoreceptors are involved in hearing.

Answer:
[tex]\boxed {\boxed {\sf Desert}}[/tex]
Explanation:
Let's evaluate the information given.
Large ears
This feature allows more heat to escape from the animal. A large ear=greater surface area= more blood vessels to release heat.Obtains water from food
In certain biomes, water is scarce. Animals can't obtain their water from drinking, so they turn to their food as a water source.Burrows underground during the day
Animals will hide underground to stay cool. It limits their exposure to the sun and heat.Based on this information, we can assume this is a desert animal. In the desert it is very hot (adaptations of large ears and undergrounds burrows) and there is little water (gets water from food).

Answer:
C The correct sequence of the transfer of information in most organisms is DNA to RNA to protein.
Explanation:
Gene expression involves the flow of information from DNA molecules to the formation of proteins. Information first flows from DNA molecules to RNA through a process called transcription. Transcription is the first step of gene expression in which an RNA especially the mRNA is synthesized from a DNA molecule by RNA polymerase enzyme. Then the synthesized mRNA is taken to the cytoplasm where it undergoes the translation process to form proteins.

Why does having low glucose or oxygen in your cells make it difficult to walk up steps
Answer:
Oxygen and glucose are both essential for energy production.
Explanation:
Glycolysis is the break down of sugar with or without the presence of oxygen to provide energy to our cells. The energy for the cell is in the form of ATP. In the presence of oxygen the process is much more efficient and is the last step in oxidative phosphorylation. In this process the Oxygen will pick up the protons that have driven the proton motif force that was used to turn the ATPase that was used to make ATP. The oxygen picks up these protons and keeps the cell pH stable and this is called metabolic water. The Dr should check the blood for the presence of both glucose and oxygen.

Why is meiosis important in maintaining genetic diversity?
Question 6 options:
A Meiosis creates diversity by cutting each chromosome exactly in half.
B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.
D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.
Answer:
We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Explanation:
Brainliest please?
Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.
Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
Other options-
A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.
C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.
D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.
