Which chamber of the heart receives blood back from the body that's low in oxygen
Answer:
superior vena cava
Explanation:
Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.

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.

Group 3 has valency +3
Group 4 has valency ±4
Group 5 has valency -3
Group 6 has valency -2
Group 7 has valency -1

The valency refers to how many bonds an atom will make in forming a molecule/compound;
This is also referred to as the combining power of an atom.
Which information can be determined using half-life?
Answer : In radioactive decay, the half-life is the length of time after which there is a 50% chance that an atom will have undergone nuclear decay. It varies depending on the atom type and isotope, and is usually determined experimentally.

If 35% of the bases in a region of the mouse genome are cytosine, what percentage in that region are adenine?
A. 15%
B. 20%
C. 30%
D. 35%
E. 40%
Answer:
A. 15%
Explanation:
DNA is composed of four nitrogen bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Chargaff's rule of base pairing states that A always pairs with T, while G always pairs with C. The total distributed percentage of the four 4 nitrogen bases must be equal to 100%. In this case, the C content is 35%, thereby G=35% (i.e., equal to C content), while the remaining 30% must be equally divided between T=15% and A=15%.

Your answer:
Answer:
Captive breeding program
Explanation:
A captive breeding program can be defined as the process of collecting wild specimen and allowing them to reproduce in an environment away from predation. This is an important part of saving endangered species. Specimens of such species are bred in zoos and similar facilities in order to build a healthy population. Sometimes, these species are successfully reintroduced back into the wild. Examples of animals that were successfully saved like this are the California condor, black-footed ferret, golden lion tamarin, and red wolf.
Question 4 of 10
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.

Explanation:
the sun plays a big part
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).
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.

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:
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.

Answer:
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.
