Answers
Complete question: The image shows the skulls of three different organisms. The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Based on the structure of the skulls, which two statements can you infer?
a) All three organisms share a common evolutionary lineage
b) Wolves do not share any common ancestors with humans and chimpanzees.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
d) Chimpanzees share more common ancestors with wolves than they do with humans.
Note: The skull figures are shown in the attached file
Answer:
a) All three organisms share a common evolutionary lineage
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
Explanation:
Although controversial, there is a theory that states that the foramen magnum is associated with bipedalism and human beings´ evolution. According to different studies, the foramen magnum moved from the posterior part of the skull to a central and ventral position. This displacement occurred as mammals began to move in two legs - bipedalism-.
When comparing different mammals skulls it seems evident that bipedalism and foramen magnum position and orientation are highly related. Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals.
In the exposed example, when comparing these three skulls, the two statements that might be inferred are:
a) All three organisms share a common evolutionary lineage. This is true because they are all mammals, and as a group, they share a common ancestor in evolution.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves. This is true because by analyzing the foramen position, we can see that both the chimpanzee and the human´s foramen is located on the ventral side of the skull. Chimpanzees´ hole is more posteriorly and humans´ hole is more anteriorly or centrally located, but in both cases, they are in ventral position. Wolves´ hole, on the other hand, is located posteriorly. As we said before, Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals. And groups closer to human beings (in this case is chimpanzee) show their foramen magnum in a similar place than those mammal groups that are further in evolution (wolves).

For example; _____is a general-purpose, non-selective growth media, _____is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and _____are selective agar for Gram positive organisms and ______agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, and _____is an example of a liquid that supports growth of a variety of organisms.
Answers
Answer:
Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; Nutrient agar is a general-purpose, non-selective growth media, Chocolate agar is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and Mannitol Salt agar are selective agar for Gram positive organisms and MacConkey agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, Nutrient broth is an example of a liquid that supports growth of a variety of organisms.
Explanation:
Growth media are classified based on their composition as:
1. General Purpose Media: These type of media support the growth of non-fastidious organisms, that do not require special nutrients for growth, and they also serve as a base for certain modified media. An example is the nutrient agar
2. enriched media: these media, like the name implies, is one that has been modified by the addition of special growth factors and nutrients called enrichment. An example is chocolate agar where lysed blood is added to nutrient base agar, when the blood cells are lysed slowly at 80°C, nicotinamide adenine dinucleotide (factor V or NAD) and hemin (factor X), are released into the medium, and these support growth of certain fastidious organisms like Haemophilus influenza bacteria.
3. Selective media: These kinds of media contain substances that support the growth of certain organisms while in turn preventing the growth of others due to the presence of certain inhibitory factors. Examples are: Mannitol Salt Agar, which supports growth of Gram-positive organisms and MacConkey agar, which supports the growth of Gram-positive organisms
4. Non Selective media: These type of media have no biases against the growth of certain organisms, that is, they do not contain certain inhibitory factors that impede the growth of certain organisms.
5. Differential media: These media contain chromogenic agents that change colour and helps to differentiate one organism from the other, making for ease of identification especially for organisms with similar properties.
Finally, a broth is a growth medium that fo not contain agar, hence, it is liquid and not solid.
You are comparing two samples of the octopus genome, one from an octopus that can make ink (sample 1), and one from an Octopus that can't
make ink (sample 2). You notice the one who can't make ink has a mutation Sample 1: ATTACAGTACTGGCA Sample 2: ATTACAATACTGGCA
Looking at the sequences carefully you determine it is a
mutation
A. Insertion
B. Substitution
C. Deletion
D. Inversion
Answers
Substitution Mutation
Explanation:
It can’t be deletion or addition as the base pairs of DNA haven’t shifted to the right or left.
If they had the second sequence would have an extra/one less base pair which isn’t the case.
It can’t be an inversion, as that’s where the base pairs from the opposite DNA strands are inverted/switched.
If it was inversion, you would have had a C instead of an A for Sample 2.
This is due to complementary base pairing where guanine bind with cytosine and adenine binds with thymine.
Therefore, this only leaves substitution as a viable answer.
The unusual patterns on a silk moths wings are one of the most stunning examples of mimicry in the wild,mimicry can protect the moth?
Answers
The question is incomplete. The complete question is as follows:
The unusual patterns on a silk moth’s wings are one of the most stunning examples of mimicry in the wild. Mimicry occurs when an organism develops a physical characteristic or behavior similar to a protective trait in another species. What do you think these moth wings mimic? Why do you think this kind of mimicry can protect the moth?
Answer:
The silk moth's mimic the physical characteristics such as changes in wings pattern that resemble another moth species that is dangerous or unpalatable to predators.
This unusual change in wings pattern provide camouflage to the silk moths and prevent predators. Predators get confuse because of the mimic spcies and consider them as toxic or untasty and won’t attack.

Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron?
Answers
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.
This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.

Answers
Answer:
its D
Explanation:
because conduction happens through solids and the others are obviously conventional current
The wax covering an iron rod melts when the rod is heated ( D ) is not a result of convection current
Convection is the transfer of heat energy from an area of higher concentration to an area of lower concentration and it occurs in fluids and gases. while conduction is the transfer of heat energy from one object to another through the direct contact of the objects and this occurs between solids.
The transfer of heat from the heated rod to the wax covering occurs because of the direct contact the wax has with the heated rod therefore it is conduction and not a convection current.
Hence we can conclude that The wax covering an iron rod melts when the rod is heated is not a result of convection current

A female had tubular pregnancy and had to remove her oviducts. Will this affect her in anyway with respect to reproduction ? justify?
Answers
Reproduction will be highly affected.
Since there are two oviducts one will be removed as a result of the ectopic pregnancy.
Hence, there will be a defect in the carrying of the ovum from the ovary to the uterus. There will be delivery of the ovum only in the the unaffected oviduct. This can lead to non-fertility.
Ectopic pregnancy is a condition in which there is an implantation of the zygote in a location other than the the uterus.
