Answer:
b
Explanation:
The correct answer as to the ocean process that exposes the coastal organisms to land-based predators would be the daily tidal patterns that leave the coastal area exposed to the land for a part of the day.
Some parts of the coastal areas become exposed to land during certain periods of the day as a result of tidal waves. When this happens, the aquatic organisms occupying these coastal areas become temporarily exposed to land predators who hunt and kill them for food.
Therefore, the correct option is b.
if a person who is blood type O marries a person who is blood type A, what are the possible blood types their children could have
Answer:
The possible blood types their children could have are A or 0.
Explanation:
The I gene determines the blood type of a person. I is the dominant allele, while i is the recessive allele.
IA dominant over i. The person presents A type of antigens. IB dominant over i. The person presents B type of antigens. IA and IB are codominant. The person presents both types of antigens, A and B. i is the recessive allele. The person does not present any antigen.Cross: a person who is blood type O with a person who is blood type A
Parental) ii x IA-
Gametes) i i IA -
Punnet Square) IA -
i IAi -i
i IAi -i
The - symbol represents the possibility of either IA allele or i allele. This is, the parental with blood type A might have the genotype IAIA or IAi
F1) 2/4 = 1/2 IAi
2/4 = 1/2 -i (-i could be either IAi or ii, depending on the genotype of the parental with blood type A)
Option 1: ii x IAIAF1) 100% IAi (The whole progeny will have blood type A)
Option 2: ii x IAiF1) 50% IAi (Half of the progeny will have blood type A)
50% ii (Halfa of the progeny will have blood type 0)
The possible blood types their children could have are A or 0.

Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.
Answer: Option E.
All of these are used by parietal cells.
Explanation:
Parietal cells are found in the stomach and they produced gastric acid(Hcl)..
HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.
Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).
Therefore it uses channels, pumps, antiporter.

Where does that air go as a result?
Answer:
Air go from one place to another due to difference in temperature of land and sea.
Explanation:
Air go as a result of wind from one place to another. Air moves from land to sea is called land breeze and from sea to land is known as sea breeze. This will occur when there is difference in temperature between sea and land. Sea breeze occurs at afternoon while land breeze occurs at night till morning. Warm air produces low pressure and cold air produces high pressure so when warm air rises, cold air takes its place and this cycle continues.
Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.
Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

A couple has just learned their neonate is diagnosed with osteogenesis imperfecta, and they
ask, "What caused our child to get this disease?" What should the health care provider teach
the couple about their neonate's condition?
Answer:
osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.
Explanation:
Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.
The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it
from either of the parent because it's a genetic disorder. The health care
provider should teach the parent about how to prevent the effect of having
such disease such as bone fractures.
Osteogenesis imperfecta is a genetic disorder inherited by offspring from
their parent. The disease involves individuals having very brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

O causes the body to produce abnormally shaped red blood cells due to the body's inability to form fibrin proteins.
o prevents the body from absorbing vitamin B12 due to the body's inability to form fibrin proteins.
Answer:
prevents blood from clotting normally due to the body's inability to form fibrin proteins.
Explanation:
Haemophilia is a genetic disorder which could be inherited and it is characterized by constant bleeding and loss of blood when injuries occur. This is as a result of the inability of the body to form fibril proteins. The fibril proteins are responsible for the production of platelets . The platelets are responsible for the clotting of blood.
This validates haemophilia being a disorder which prevent blood from clotting normally due to the body's inability to form fibrin proteins.

Predict what will happen to the following lung volumes and capacities during strenuous exercise. Assume that you are comparing from a baseline of normal resting respiration.
Lung Volume or Capacity Predicted change from resting baseline : Use Increase, Decrease or No Change
TLC (total lung capacity)
No change
VC (Vital capacity)
IC (Inspiratory capacity)
FRC (Functional residual capacity
TV (Tidal volume)
IRV (Inspiratory reserve volume)
ERV (Expiratory reserve volume)
RV (Residual volume)
Answer:
During intense exercise:
lung capacity increases
vital capacity increases
respiratory capacity increases
functional residual capacity increases
tidal volume increases
the inspiratory and expiratory reserve volumes decrease as does the residual volume.
Explanation:
Residual volumes decrease because having better lung capacity, better development of the secondary skeletal muscles that collaborate in expiration and inspiration, these are given in a better way, and more effectively.
If these processes take place more efficiently, their potentiality increases and expiration and inspiration move a large current of air into the lungs, thus leaving less reserve airs.
Those people who have increased exhalation or inspiration reserve, have a weak activity of the musculature in the processes and function as "stagnant air" which is synonymous with a lack of physical activity or aerobic capacity.
It is important to clarify that all the above processes are accompanied by an increase in the size of the chest cage

fur color in mice is affected by a single gene the gene for fur color has two alleles: b that causes dark brown fur and b that causes light brown fur. What is or could be the genotyes of a mouse with dark brown fur
Answer:
(BB) or (Bb)
Explanation:
Given that (B) allele , is responsible for fur that is dark brown, and (b) allele is responsible for fur color that is light brown, the dominant allele is (B) allele for dark brown fur. Dark brown fur allele would always express itself over the recessive allele, (b).
For a mouse that has dark brown fur, the possible genotype it could have is either (BB) => 2 dominant allele, or (Bb) => 1 dominant allele and a recessive allele. The dominant allele would always express itself even in the presence of the recessive allele.
If bacteria transformed with a recombinant pUC18 plasmid produce white colonies when grown on plates containing ampicillin and Xgal, which of the following is least likely?
a. They produce β-lactamase that provides resistance to ampicillin.
b. They carry a vector that contains a DNA fragment inserted into the multiple cloning site.
c. They produce functional β-galactosidase that cleaves X-gal.
d. They carry a vector with a lacZ gene that has been disrupted and rendered nonfunctional.
e. They carry a vector with the bla gene used as the selectable marker.
Answer:
c. They produce functional β-galactosidase that cleaves X-gal.
Explanation:
β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.

Xylem is found towards the center of the stele and phloem towards the outside of the stele. 18) How does this compare to their arrangement in the stem? 19) The meristematic region is protected in the root by the presence of a root cap. How is the meristematic region protected in the stem tip? 20) In which of these regions would you expect to find the specialized cells of vascular tissue? 21) In which of these regions are the cells genetically identical? 22) Why?
Answer:
Epidermis layer is responsible for the protection of meristematic region.
Explanation:
Meristematic region is protected in the stem tip by epidermis which consist of dead layer of cells. Epidermis is the outer layer of stems, leaves, flowers and fruits which is responsible for the protection of inner part from damage. Vascular bundle such as phloem present near the boundary of the stem while the xylem is present in the inside of the stem. In the inside layer of the stem, all the xylem cells are genetically identical while the layer that is present at the edge of the stem is phloem in which all the cells are genetically identical to each other.

How does the movement of particles of matter change when temperature increases?
Decreases
Increases
Increases then decreases
Does not change
Answer:
Increases
Explanation:
The movement of particles of the matter increases with the increase in temperature.
The particles gain kinetic energy with increasing temperature and move in faster rate.
For example: When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.
Hence, the correct answer is "increases".

A) The repressor will no longer bind to the operator.
B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.
Answer:
D) The lac operon will function normally.
Explanation:
The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.
If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.
Promotor:
It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.
