Answer:
Cerebral hemispheres: The cerebrum's outer layer, it is split into two hemispheres and is highly folded. These two hemispheres make up the cerebral cortex. This controls most of our senses, intelligence, personality, conscious thought and high-level functions, such as language and verbal memory.
Cerebellum: Controls balance, co-ordination of movement and muscular activity.
Medulla oblongata: Controls unconscious activities such as heart rate and breathing rate.
Hypothalamus: Regulates temperature and water balance within the body.

there are 525600 minutes in a year. when you divide that by 11,680 you get 45 minutes. I could be wrong, but I believe the answer is 0.4280821
Assuming you started with a saturated hemoglobin molecule, how many molecules of oxygen would need to be released in order for the hemoglobin to be 75% saturated
Answer:
only one oxygen molecule
Explanation:
Hemoglobin (Hb) is an iron-containing oxygen-transport protein localized in vertebrate red blood cells (i.e., erythrocytes). Moreover, the heme group is a component of the Hb protein which is capable of binding or releasing molecular oxygen. Hb consists of four globular protein subunits, and each subunit contains a heme group. This group (heme) binds to an oxygen molecule in a manner that each Hb protein can bind to four oxygen molecules in order to transport them throughout the bloodstream.

Which type of joints allows movement
Answer:
The correct answer would be - synovial joints.
Explanation:
Synovial joints are the joints that allow bones to move as these joints are able to great movement freely of the three structural joints. These joints have synovial fluid which helps and enabling the structures of the joints to move smoothly against each other.
They also called diarthroses which means freely movable. Ball and socket joints is a type of synovial joint that allows movements in all direction with help of muscles attached to it. Hip joint and Shouder joint are examples of such joint.
Answer:
Synovial joints
Explanation:
Synovial joints achieve movement at the point of contact of the articulating bones.
Synovial joints allow bones to slide past each other or to rotate around each other. This produces movements called abduction (away), adduction (towards), extension (open), flexion (close), and rotation.

why does the addition of phosphate compounds to aquatic areas have a dramatic effect on biological productivity
Answer:
Explanation:
The presence of the phosphates compound here act as limiting factors for plant growth in aquatic ecosystems, because they do not dissolve easily in water . Then eutrophication( this is the gradual rise in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem.) starts acting wherever there is too much phosphate, it promotes excessive amount of algae and it will exhaust the oxygen.

The inflammatory response does not: Question 15 options: Replaces damaged tissue with healthy tissue Prevents the spread of disease to surrounding tissues Starts the repair process of the tissue Disposes of the cellular debris The inflammatory response does all of the above.
Answer:
The correct option is Replaces damaged tissue with healthy tissue
Explanation:
This is because inflammatory response refer to series of occurrences that happens when tge body tissues suffer injury from chemicals, toxins, heat,trauma or other things. Tge damaged cells releases chemicals like histamine and make the blood vessels to accumulate fluid and then swell. The chemicals then separate the foreign substances from the normal one. These chemicals attracts white blood cells called phagocytes which swallow up the dead damaged cells

All you need is on the photo
Answer: B
Explanation:
When immigration into an area is higher than emigration out and with other factors kept constant, you will have a situation where population will increase.
This is the case in the point of the graph labelled B. We can see a rise in population so immigration must be more than emigration. In the other points, the population is reducing which means that more orca whales are leaving than coming in.

If a paramecium swims from a hypotonic to an isotonic environment, will its contractilevacuole become more active or less?
Answer:
Less.
Explanation:
Its contractile vacuole become less active because of the same concentration of water in both the body and outside environment. Contractile vacuole is responsible for the removal of excess liquid with the help of contraction. In isotonic environment, there is no flow water occur inside or outside of the cell due to the presence of equal amount water in both the environment i. e. cell and outside environment so due to equal amount of water, contractile vacuole become less active.
You are solving a density problem, where density = mass/volume. Your volume of liquid is 2.1 milliliters. Your mass of the liquid is 2.811 grams. What is the density of the liquid using the correct number of sig figs?
Answer:
Density = 1.3386kg/m³
Explanation:
Given the following data;
Volume = 2.1 millimeters to meters = 2.1/1000 = 0.0021 meters
Mass = 2.811 grams to kilograms = 2.811/1000 = 0.002811 kilograms
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Substituting into the equation, we have;
[tex] Density = \frac {0.002811}{0.0021} [/tex]
Density = 1.3386kg/m³

Which explanation describes why males are more likely to exhibit sex-linked disorders than females? Males have two X chromosomes that amplify all sex-linked disorders. Males have one X chromosome on which most sex-linked disorders are located. Males have only one functional sex chromosome on which all gender traits are located. Males have multiple sex chromosomes that mutate causing sex-linked disorders to become visible.
Answer:
males have one X chromosome
Explanation:
The explanation that describes why M are more likely to have linked disorders than W is that M have an X chromosome on which most linked disorders are located.
InheritanceLinked inheritance refers to genes located on chromosomes that are involved in trait determination.
In humans, the male chromosome Y has few genes. On the other hand, the female chromosome X has a large number of genes involved in the determination of various characteristics.
XY chromosomes have small homologous regions at their ends. Thus, there is practically no recombination between their genes.
When the altered gene is on the X chromosome. This type of inheritance has a recessive pattern.
It is the maternal inheritance. In this case, sons inherit X chromosome genes only from their mother. Meanwhile, F daughters inherit one from the father and one from the mother.
The manifestations will be present because they have only one X chromosome, that is, they do not have any normal gene for that characteristic.
With this information, we can conclude that the manifestations will be present in men, as they have only one X chromosome.

Food production and food availability affect millions of people worldwide. What are supporting arguments that it is not to the advantage of any group to provide food to others?
Answer:If increases in supply do not keep pace with growth in demand, food prices rise, attracting resources into food production. If supply grows faster, food prices and farm incomes fall, driving resources out of agriculture. Resources may not move fast enough to correct imbalances.
Explanation:
Answer:
Food production and availability is a problem for many people throughout the world. Many people try to help this problem by trying to provide food for those in need, but this isn't a real advantage to anyone. When people buy more of one a product to donate, it causes an increase in demand that the supply may not be keep up with causing the prices to increase, making it harder for everyone to afford it Even if the supply increases but then produces more than demanded the prices for the particular product will drop, resulting in the farmers not being paid enough, or growing more could lead to the land losing resources faster than normally.

Which phylogenetic tree shows that lactation--the production of milk to feed young--is a homologous trait in humans, dogs, and bats (but not in birds and lizards)
Answer:
The correct answer is - choice 1 in the image.
Explanation:
In this given question there are four phylogenetic trees are given among these four trees one tree shows the milk production to feed young ones which is mologous case in humans, bats, and dogs as they show lactation whereas lizards and birds do not show lactation.
In these four the first option shows the homologous condition at the second branch where milk production is divided from lizard and birds.
Genes A and B are 10 map units apart and genes B and C are 20 map units apart, with gene B located between genes A and C. What would be the expected amount of double crossovers for a trihybrid test cross
Answer:
2% of the progeny will be double crossovers for the trihybrid test cross
Explanation:
By knowing the positions of genes, we can estimate the distances in MU between them per region.
Genes A and B are 10 map units apart (Region I)Genes B and C are 20 map units apart (Region II)Genes A and C are 30 map units apart----A-------10MU--------B-------------20MU-------------C---
Region I Region II
We can estimate the recombination frequencies by dividing each distance by 100.
• recombination frequency of A-B region = 10MU / 100 = 0.10
• recombination frequency of B-C region = 20MU / 100 = 0.20
Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:
EDRF = recombination frequency in region I x recombination frequency in region II.
EDRF = 0.10 x 0.20 = 0.02
2% of the progeny will be double crossovers for the trihybrid test cross
