Answer:
Since Skull is the most complete fossil, the features of the skull that reflects Humans as bipedal omnivores are: The teeth and the foramen magnum.
Explanation:
Humans are bipedal because they can move with their two legs, and they are omnivores because of their ability to eat both meat and plants.
The teeth on a skull are the most important indicators of what an animal eats, and it even shows if an animal is a predator or prey. Humans have different sets and shapes of teeth for different purposes making them an example of heterodont dentition.
The pelvis, knee, and foot bones should be the best to tell us about how an animal moves, however, the foramen magnum which opens for the spinal cord to pass to the brain, could also show whether how the animal moved.

If two balls have the same mass, but ball P is twice as large as ball Q, which one will have the greater density?
If ball X is twice as big as ball Y and weighs only half as much as ball Y, then which one will have the greater
density?
mious Activity
Answer:
Ball A has more density.
Explanation:
Density is found using mass divided by volume. Let's say ball A has a mass of 6 grams, and ball B has a mass of 3 grams. If the volume for both is 1 mL, then ball A has more density.
The protein salmon has an isoelectric point of 12.1. Suppose you did a pH titration of a solution containing salmon. At what pH will the protein aggregate
Answer:
The correct answer is - 12.1.
Explanation:
In the case of the same isoelectric point of protein and the pH value of the solution, it is the only condition when aggregation of proteins takes place.
When there is intrinsically disordered proteins or misfolded proteins aggregates known as the protein aggregate. So for the first aggregation takes place at pH= 12.1.

The categories are based on the types of reactions that they catalyze. What type of enzyme can join together two molecules to make a larger molecule such as a long strand of DNA
Answer:
DNA ligase.
Explanation:
DNA ligase is a type of enzyme that is responsible for join together of two molecules to make a larger molecule such as a long strand of DNA. This enzyme joins the end of two DNA molecules making it a long strand of DNA. In DNA cloning process, restriction enzymes and DNA ligase enzymes are used to incorporate genes and other pieces of DNA into plasmids so we can say that DNA ligase is responsible for long strand of DNA.

d. medulla oblongata
e. choroid plexus
f. pons; medulla oblongata; midbrain
g. hypothalamus
h. cerebrum
i. epithalamus
j. cerebrum
k. cerebellum
Explanation:
The brainstem is the posterior part of the brain that connects the cerebrum with the spinal cord. The brainstem can be divided into three parts: midbrain (i.e., mesencephalon), the pons (i.e., metencephalon), and the medulla oblongata (i.e., myelencephalon). The mesencephalon is a region of the brain composed of the tectum and tegmentum, which play fundamental roles in motor movement, auditory and visual processing. The corpora quadrigemina is found at the tectum region of the midbrain. The diencephalon is a small part of the brain located above the brainstem (between cerebral hemispheres); which contains the thalamus, hypothalamus, subthalamus, and epithalamus. In turn, the epithalamus is composed of the habenular nuclei, pineal gland, and the stria medullaris thalami. The cerebral aqueduct is a narrow channel (approx. 15 mm) in which the cerebrospinal fluid flows between the third ventricle and the fourth ventricle. The medulla oblongata is a long stem-like structure located in the brainstem of the brain, just in the place where the brainstem connects the brain to the spinal cord. The choroid plexus is a complex network of capillaries located at the cerebral ventricles of the brain, which serve to produce cerebrospinal fluid through ependymal cells that line the ventricles of the brain. The cerebellum is a major structure of the hindbrain and consists of the cerebellar cortex and a core of white matter having the cerebellar nuclei.

a. reaction sequences carry out electron transfer phosphorylations.
b. processes generate ATP.
c. processes involve electron flow.
d. systems are lodged along and within a membrane surface.
e. all of the above.
Answer:
e. all of the above
Explanation:
Photosynthesis and respiration are two complementary processes.
Photosynthesis occurs in chloroplasts. The electron transport chain is placed in the thylakoid membrane, where it occurs light-dependent reactions.Respiration occurs in mitochondria, in the internal membrane, where is the electron transport chain.Photosynthesis needs solar radiation to produce organic compounds.The respiration process needs organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compoundsRespiration transforms organic compounds into CO₂.In the photosynthesis process occurs a release of oxygen, which is used during the respiration process. Both processes are part of the carbon biological cycle.Both processes use electron transport chains to capture energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products of light-dependent reactions are oxygen, ATP, and NADPH.which statement correctly describes cell differentiation

In this task, you’ll record the direction of a compass as it’s placed at different points around a magnet. The investigation will try to answer the question, Do two magnets create magnetic force fields that allow them to interact without touching?
Part D :
How might someone dispute the results of this investigation? How might you counter the argument?
Answer:
It could be argued that there is a separate force acting upon the investigation. Or that the room is invalidating the results for some reason. Or that an error was made in measurement.
There are a thousand and one ways to try to dispute an investigation like this. However, for every argument that can oppose it, a counterargument can easily be made.
For instance, controlling the variables invalidates about 90% of any possible claims to the contrary. The majority of arguments would stem from the fact that it is nearly impossible to completely prove something in fear of external factors. The solution? Control the external factors.
So, in conclusion, a person could dispute the results of the investigation by claiming that something invisible like magnetics could not possibly be proven to exist, because there are all sorts of things that could be influencing the investigation. The way to counter the argument would be to prove yourself that the environment is controlled, and that nothing could be influencing the investigation.

What is NOT an effect of growth hormone?
a. Growth hormone directly stimulates osteoblasts in the periosteum to promote appositional growth.
b. Growth hormone increases the rate of mitosis in the epiphyseal plate of growing bones.
c. Growth hormone promotes the closure of the epiphyseal plate.
d. Growth hormone increases the activity of osteogenic cells.
C. Growth hormone promotes the closure of the epiphyseal plate.
The closure of the epiphyseal plate is NOT an effect of growth hormone (option c).
The epiphyseal plate is a layer of hyaline cartilage between the epiphyses and metaphyses at the ends of long bones.
The epiphyseal plate is completely closed when bone growth is completed (around age 18 to 21 years).
Different hormones (i.e., testosterone and estrogen) released at puberty initiate the closure of epiphyseal plates.
In conclusion, the closure of the epiphyseal plate is NOT an effect of growth hormone (option c).

Recall that one approach to the study of cell cycle regulation has been to fuse cultured cells that are at different stages of the cell cycle and observe the effect of the fusion on the nuclei of the fused cells (heterokaryons). When cells in Gl are fused with cells in S, the nuclei from the Gl cells begin DNA replication earlier than they would have if they had not been fused. In fusions of cells in G2 and S, however, nuclei continue their previous activities, apparently uninfluenced by the fusion. Fusions between mitotic cells and interphase cells always lead to chromatin condensation in the nonmitotic nuclei. Based on these results, identify each of the following statements about cell cycle regulation as probably true (T), probably false (F), or not possible to conclude from the data (NP). Sort each statement into the appropriate bin.
1. The transition from mitosis to G1 appears to result from the disappearance or inactivation of a cytoplasmic factor present during M-phase.
2. The activation of DNA synthesis may result from the stimulatory of one or more cytoplasmic factors.
3. Gl is not an obligatory phase of all cell cycles
4. The transition from G2 to mitosis may result from the presence in the G2 cytoplasm of one or more factors that induce chromatin formation.
5. The transition from S to G2 may result from the presence of a cytoplasmic factor that inhibits DNA synthesis.

Explanation:
In somatic cells, the cell cycle can be divided into 1-the interphase, 2-the mitotic phase or M phase, and 3-the G₀ phase. In turn, the interphase of the cell cycle can be divided into three phases: 1-the gap 1 (G1) phase or growth 1 phase, 2-the S phase (DNA replication or DNA synthesis), and 3-the gap 2 (G2) phase or growth 2 phase. During the G1 phase, the cell synthesizes key enzymes which are required during DNA replication (S phase) and cell division (M phase). Cytoplasmic factors are proteins and messenger RNAs (mRNAs) that control cell functions during the cell cycle. This cycle is modulated by proteins known as control factors, i.e., cyclins and cyclin-dependent kinases (Cdks) that work together to control the progression through different phases of the cell cycle. The transition from S to G2 occurs after DNA replication. This transition (S to G2) is controlled by a DNA damage checkpoint orchestrated by the ATM (Ataxia telangiectasia mutated) and ATR (Ataxia Telangiectasia and Rad3 related) kinases which are recruited to DNA damage sites. Moreover, the transition from G2 to M phase is mediated by the accumulation of mitotic inducers, which lead to an increase in the activity of mitotic kinase and finally trigger mitotic entry.
in order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many ___ bonds
Answer:
In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many hydrogen bonds
Explanation:
In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.
