Answer:
increases; protein denaturation occurs
Explanation:
One of the characteristic of enzymes is the sensitivity to temperature .
Enzymes are sensitive to the changes in the environmental temperature.The enzymatic activities increases with increase in temperature,up to the optimum of 37 degrees in most animals.
However,once the optimum temperature has been exceeded,enzyme activities drops.This is because below optimum the rate of collision between the enzyme active sites and substrate molecules is very high,therefore more products are formed which increases the rate of reactions.
At temperature above the optimum,the high temperature breaks the bonds,especially the hydrogen bonds holding the 3D structure of the active sites.Therefore,substrate molecules can not fit into the active site,and therefore enzymatic actives of the enzyme is affected,and the enzyme is said to be denatured

Hemophilia is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree. Who has hemophilia in the pedigree that is shown? A)John and Ann B)Fred and Luke C)John, Charles, Jack, and Irene D)Ann and Marie
Answer:
B)Fred and Luke
Explanation:
On the pedigree, it is obvious that they suffer from hemophilia because they appear colored, but males(XY) need only one allele for hemophilia to be sufferers.
In hemophilia, it is x linked recessive disorder in males having X and Y chromosomes, so he need only one x chromosome in recessive manner, hence in pedigree analysis Fred and luke having has hemophilia, hence option b is correct
What is hemophilia?Hemophilia is a hereditary bleeding disorder in which the blood lacks to clot properly. This can occur for both spontaneous and post-injury or operative bleeding.
On the pedigree, it is observed that they suffer from hemophilia because it is x linked recessive disorder, they appear colored, but males (XY) need only one allele for hemophilia to be sufferers.
Blood contains several proteins known as coagulation factors that can assist in the prevention of bleeding. Although its rare, acquired hemophilia is a serious illness.

Jenna began making a model to show the processes which resulted in the formation of oceans. Art shows three boxes connected with arrows. The label on the first box is 'Water fills the basins', second box is 'Segments of Earth's crust move',and the third box is labeled with a question mark. Which of the following would be the next step in the process? Crust is broken down Earth’s crust moves Earth’s plates meet Sea floor spreading
Answer:
Crust is broken down
Explanation:
In the formation os oceans, at first water fills the basins, in the second step segments of Earth's crust move and in the third step crust is broken down.
In the oceans when water fills the basin, it allows the Earth's crust to move which makes it folded or break apart. When the crust is broken down along with deep cracks, it is filled with water from streams and rainfall flowing in the ocean.
Hence, the correct option is "Crust is broken down".
Answer:
Earth's plates meet
Explanation: After Earth's crust formed, and water filled the basins, giant segments of the crust began to move. These segments are known as lithospheric plates or tectonic plates. The plates float on Earth's molten interior like rafts of rock. The plates move around, driven by convection currents from the Earth's mantle. The plates move over and under and past each other. Where the plates meet, Earth's crust is constantly formed and re-formed.
Areas on the moon called maria Select one: a. are seas of water. b. consist of basaltic lava. c. formed a million years ago. Clear my choice
Areas on the moon called maria consists of basaltic lava. Option B is correct.
The areas on the moon called maria are not actually seas of water, as option a suggests. Instead, they are large, dark, flat areas on the moon's surface. These areas were formed by ancient volcanic activity.
Maria are made up of basaltic lava, which is a type of lava that is low in viscosity and can flow easily. When volcanic eruptions occurred on the moon in the past, this lava flowed out onto the surface and covered large areas, creating the maria.
These volcanic eruptions and the formation of the maria took place billions of years ago, not just a million years ago as option c suggests. They are remnants of the moon's early history when volcanic activity was more prevalent.

Answer:
The medication label should be checked by comparing it with the MAR (Medication Administration Records or therapeutic documentation care plan TDCP).That is the label printed on the medication should be compare with the Medication Administrations records
Explanation:
Ideally this should be done three times, when it is removed from the medication cart,and before and after it was removed form the medication cart.
Besides,the date of expiration should be checked,and the regulations concerning administrations of multi-does vial should be taken into considerations.
The medications mode of storage should be taken into confederation,proper storage must be ensured.
Generally the application of medication through injection into the muscles for faster absorption into the blood streams for fast distribution is called IM. This is aided by the rich blood supply to the muscles.Therefore it is a faster mode of blood application than the subcutaneous routes.

omosexuality is seen only in humans. has been documented for only a few hundred years in only a few societies. likely reflects the input of a number of genes and environmental factors. is inherited from a mutation on the X chromosome. is only the result of environmental influences.
Answer:
Homosexuality likely reflects the input of a number of genes and environmental factors
Explanation:
Sexual orientation can be defined as the attraction that experiments an individual self-identified with a particular gender (either male or female) to other persons according to their sex, this orientation may be classified into three categories: heterosexual (attraction for people of opposite sex), homosexual (same-sex) and bisexual (either sex). In the last years, the mechanisms involved in sexual orientation have been subject to intense research. In this regard, the main part of the scientific community agrees that sexual orientation is the result of the complex interaction between genetic and environmental factors. This hypothesis is supported by the fact that genes whose expression is associated with particular human behaviors, including sexual orientation, have been recently identified and mapped. Moreover, it has been shown that environmental factors such as, for example, hormone exposure before birth (i.e., during fetal programming) may also determine sexual orientation.
In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

c. irreversibly inhibiting critical enzymes.
d. destroying enzymes by proteolytic cleavage when they are needed in biosynthetic pathways.
e. accumulating unnecessary proteins.
Answer:
b. making products that are not needed by inhibiting the activity of enzymes in biosynthetic pathways allosterically.
Explanation:
The feedback inhibition is a method of cellular control were the active cellular enzymes is inhabited and it allows the cells to regulate how enzymes are needed to produce at the end. This feedback acts as a first enzyme amino acid production and is usually complete through the allosteric site. It changes the shapes and behavior of the active cell.explain what is meant by emergent properties when explaining how a beaker full of chemicals is different than an animal made of that same mix of chemicals
