Answer:
A gene is a short section of DNA. your genes contain instructions that tell your cells to make molecules called protein
Answer:
Basically gene produces a functional product such as a protein which regulates the functioning of our cells via carrying out different processess.
Explanation:
Genes are short segments of our DNA that code for functional products such as proteins. Proteins basically do everything in your cells and your phenotype (what you look like and how you cells behave) everything is controlled by these functional products that a gene makes.

Here is a hypothetical situation: An area of the country has received a record amount of rainfall this year coupled with a mild winter and a warm spring and summer. As a result the mosquito population is exceptionally high. Mosquitoes are not pathogens to humans. However, mosquitoes can greatly affect the rate of infection for several types of human pathogens. Pick and describe two pathogens that you should expect to see at higher frequency because of this booming mosquito population.
Answer:
Zika virus and West Nile virus are the two pathogens which causes more diseases due to increase the population of mosquito.
Explanation:
Zika virus belongs to the family of Flaviviridae. Aedes mosquitoes which are active at day time are the carrier of this virus. West Nile virus is also spread through the bite of mosquito. The infected mosquito is the main cause of spreading of this disease. This virus is spreading too fast in the United States of America in the summer season where the population of mosquitoes increases.
Relaxation of the diaphragm muscle plays a major role in expanding the lungs.
True
False
Answer:
False
Explanation:
You relax the diaphragm muscle by exhaling. When the diaphragm muscle is relaxed, the lungs contract. When the diaphragm muscle expands, the lungs also expand. Therefore, relaxation of the diaphragm muscle does NOT play a major role in expanding the lungs.

Cells must maintain an appropriate level of fluidity across their membranes. Hot temperatures lead to greater membrane fluidity. What might you then expect to find regarding the membrane composition of bacteria from very hot environments
Answer:
Thermophilic bacterial are rich in large quantity of thermophilic lipids in the cell membranes. This components made the membrane to be impermeable at high temperature, and therefore a good adaptation for the hot environment.
At high temperature,proton permeability increase, sodium permeability also increases but to a ;lesser extent, but Lipid is independent of this temperature rise.
Hence, these organisms rely on the less permeable Na+ for the maintenance of high sodium motive force.it is the energy derived from this that the cell membrane needs to maintain stability, coupe with the lipid content.

is heat involved in producing all three classes of rock.
Answer: yes. metamorphic, sedimentary, and igneous
Explanation:
Sedimentary and igneous rock is transformed into metamorphic rock inside the Earth by heat, pressure, and melting, so heat is involved in producing all three classes of rock.
What are the classes of rock?From eroding parent material, sedimentary rock is created. The source material may be sedimentary, metamorphic, or igneous in origin.
Strong heating causes hot liquid rock (magma) to break through the Earth's surface and solidify as igneous rock. This rock is worn and eroded throughout time, restarting the cycle.
The existing rock must stay solid and not melt in order to produce metamorphic rock. The rock will melt and turn into the lava if there is too much heat or pressure. An igneous rock, not a metamorphic rock, will develop as a result of this. Think about the shape changes in granite.
Therefore, sedimentary and igneous rock is transformed into metamorphic rock inside the Earth by heat, pressure, and melting.

c. magnify 1000x
d. concentrate light coming from the bulb
e. none of the above
Answer:
1. Condenser
2. None of the above
3. Magnify 1000x
Explanation:
1. Illuminators provides the stable light source in the microscope. It can be reflected using a mirror for a built in microscope. Condenser is made up of two lenses which helps collect and concentrate light. The light beams passes through the centre of the lenses.
Total magnification is objective magnification × Ocular magnification
It makes the object appear bigger than it is. Any of the objective magnification can be uses to achieve the specific size. Objective ranges from 10-100
Oil immersion makes image appears brighter, they increase the refractive index. It is used with 100x objects to achieve a clearer image.

if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is 147 years what is the age difference between the oldest and the youngest
Answer:
The age difference between the oldest and the youngest is 48.
Explanation:
Given the following data;
The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.
The ratio of the ages of Esinam (E) and Larry (L) is 3:5.
The sum of the ages of all three is 147.
Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);
LCM of 3,5 = 15.
Hence, the ratio of the three ages is now;
K:E:L = 9:15:25
Let their ages be denoted by x;
[tex]K:E:L = 9x:15x:25x[/tex]
The sum of all three ages is;
9x + 15x + 25x = 147
49x = 147
x = 147/49
x = 3.
To find the age difference between the oldest and the youngest;
The oldest is Esinam = 25x
The youngest is Kisii = 9x
Therefore, 25x - 9x = 16x
Substituting the value of x, we have;
x = 3; 16x = 16(3) = 48.
The age difference between the oldest and the youngest is 48.
The stimulus interval has a profound effect on the contraction force of the muscle. In your own words explain what happened when the muscle was stimulated in rapid succession. At which interval did the volunteer's muscle twitches begin to merge together (summate)
Answer:
The skeletal muscle is stimulated by means of action potentials that are caused by the neuromotor plate. These action potentials are one after the other and can become cumulative once the muscle fibers pass the refractory phase of the action potential.
The refractory stage is that stage in which action potentials are not admitted, therefore where the muscle fibers do not accept stimuli to contract.
Once this refractory stage is over, more action potentials can be admitted, which would be summative and the muscle fiber would contract with greater power.
Explanation:
If a muscle is repeatedly stimulated, the contraction will be weaker or the muscle will fatigue more easily, triggering muscle failure.
If the muscle is stimulated with a longer pause between contraction and contraction, the action will be performed with more power.
What physiological alterations occur at both the vasculature and heart functioning level? (really stuck on this one, please help.)
Answer:
Most physiological alterations during aging and it is usually characterized by the deposition of a pigment called liposfuscin.
The valves of the heart also becomes stiff and thickened as a result of the pigment mentioned above. This makes the flow of blood slower than normal and contributes to cardiovascular diseases such as Stroke, high blood pressure etc.
Which of the following are true?

III. Crossing over and independent assortment do NOT affect the diversity of offspring produced
by random fertilization.
Select one:
o
a. I and III
b. II and III
c. I, II, and III
d. I and II
Answer:
1 and 2
Explanation: Random Fertilization means that any one sperm may fertilize any one egg as a chance event.
Random fertilization allows for a lot of diversity in offspring.
Random Fertilization means that any one sperm may fertilize any one egg as a chance event and allows for a lot of diversity in offspring. So, the correct option is (D).
What is Random Fertilization?Random fertilization refers to random mating. In this, during sexual reproduction, male gametes and female gametes which fuse to produce offspring are randomly selected from the pool of male and female gametes.
Random fertilization increases genetic diversity. When a male gamete and a female gamete finally meet which results in a large number of genetic possibilities built up during independent assortment and crossing over.
The example of Random Fertilization is when the two individuals mate, where each is capable of producing more than 8 million potential gametes, then the random probability of any one sperm and egg coming together showing 70 trillion different combinations.
Thus, Random Fertilization means that any one sperm may fertilize any one egg as a chance event and allows for a lot of diversity in offspring. So, the correct option is (D).

Name the mandibular motion resulting from the following combinations of muscle contractions: ________
a) B Masseter, B Temporalis, B Medial Pterygoid
b) L Lateral Pterygoid, R Masseter
c) B Lateral Pterygoid, B Medial Pterygoid
d) B Lateral Pterygoid, B Digastric
Answer:
c) B Lateral Pterygoid, B Medial Pterygoid
Mandibular motion is by combinations of B Lateral Pterygoid, and B Medial Pterygoid contraction which controls the mandible's closure, hence option c is correct.
What are muscle contractions?There are several of these, including the masseter and temporalis muscles, which control the mandible's closure; the medial pterygoid muscle, which controls the mandible's closure and lateral movements.
The lateral pterygoid muscle, controls the mandible's opening, deviation to either side, and anterior movement.
The lateral pterygoid muscles on the side that is contralateral to the excursion are contracted to move the jaw to one side (laterotrusion), with the help of the posterior temporalis muscle on the same side (ipsilateral).
Therefore the combination of B Lateral Pterygoid, and B Medial Pterygoid creates mandibular motion, hence option c is correct.

Amanda hates her new student ID photo. Her hair looks dry, the extra weight she's gained shows, and her neck looks fat. Amanda's also been feeling very tired and mentally dull. Amanda goes to the clinic where you are working. You draw her blood. The test results show her T4 levels are low and her TSH levels are low. Later she is given a TSH stimulation test in which TSH is injected and the T4 levels are monitored. After TSH injection her 14 levels rise. A) Does Amanda have problems with her pituitary or with her thyroid gland? B) How did you come to your conclusion?
Answer:
A) Pituitary Gland B)By analysing the given observations in the question.
Explanation:
THS, thyroid stimulating hormone, is an hormone produced by the pituitary gland and in return it stimulates the thyroid gland that produces hormones such as T3 and T4.
We can conclude from the given information that Amanda's thyroid gland does not have a problem with producing and secreting the T3 and T4 hormones when THS is present in her body.
But the low THS levels show that the problem is with her pituitary gland causing her to have low levels of THS.
We can reach this decision by analysing the given information.

True or False: Cells will generally divide when they're too large
Answer:
true
Explanation:
the cell becomes two
Yes, this statement is TRUE cells will generally divide when they're too large
Why do cells divide when they get too big?The larger a cell becomes, the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane.
When cells will generally divide?The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.
