Answer:
there is less fluctuation in abiotic factor such as temperature.
Explanation:
Organisms with a narrow range of temperature tolerance would most likely be found where there is less fluctuation of temperature or variation in temperature because the organisms are tolerant to less variation in abiotic factor such as temperature so if the temperature goes very high or low, then the organism is not able to tolerate and die. So we can say that less variation in temperature are the regions where organisms with a narrow range of temperature tolerance can be found.

Explanation:
Glucose is present in blood plasma at a concentration of approximately 80 mg/dL. A typical 70 kg human has approximately 5 L blood, which is 55% plasma. Using the glucose concentration of Sprite that you calculated in the previous question, how many mL of Sprite does a human need to drink to reach a plasma glucose concentration of 80 mg/dL, assuming none is mobilized?
Answer: 48.93 mL of sprite
Volume of blood in 7 Kg human = 5 L
Percentage of plasma in blood = 55%
Volume of plasma in 5 L blood = (1 L = 10 dL)
Concentration of glucose in plasma = 80 mg/dL
Amount of glucose present in 27.5 dL : 80 mg /dL × 27.5 dL= 2200 mg
Let the volume of sprite with 2200 mg glucose be x
Concentration of glucose in sprite = 44.96 mg/mL
Explanation:
What might happen to biodiversity in area 1 if the new bird species moved into the area
Answer:
New bird species may alter the ecosystem and modify the trophic chain when they become invasive, leading consequently to the loss of biodiversity
Explanation:
Invasive (also known as alien) species are non-native species capable of spreading into a new area where they have a drastic impact on the ecosystem. An invasive species may cause an important loss of biodiversity and modify the food web in an ecosystem by replacing native species. Examples of invasive bird species include the house sparrow, European starling, cattle egret, rock pigeon, etc. Nonetheless, it is important to highlight that not necessarily new bird species will become invasive (it will depend on their effects on the ecosystem).
The cheek smear slide is made by taking a q-tip or toothpick, rubbing it on the inside of your mouth (to remove cells) and then wiping or smearing it onto a blank slide. A stain is used on the cells so that you can see them, otherwise, they would be see-through. Look at the cheek smear slide using the 10x objective (total magnification of 100x). Approximately how many cells do you see inside the red circle
Answer:
The number of cells that will be viewed will depend on the size of the cells and the size of the red circle on the slide.
Explanation:
The cells have different sizes and this influences the number of cells that you will be able to view under a microscope.
The intensity with which the smear was made will also influence the number of cells viewed, as well as the quality and quantity of dye you used on the slide.
In summary, we can say that the number of cells that you will be able to visualize is relative and only the experience, in itself, will be able to determine a number.

Which options describe the structure of a water molecule? Select all that apply. 1. the molecule has an overall straight shape 2. the hydrogen atoms are attached to the oxygen atom at an angle 3. the molecule has an overall bent shape 4. the hydrogen atoms are attached at opposite ends of the oxygen atom
Answer:3 and 2
Explanation:
For water molecule all options are correct here.
What is the structure of a water molecule ?
Water occupy around 70% of the earth’s surface, it make up about 95% of the living organisms.
Each water molecule is composed up of one molecule of oxygen and two molecules of hydrogen by forming a covalent bond .
A strong bond of attraction between nucleus of the oxygen nucleus and electrons of hydrogen has been seen which form an angle 105° between hydrogen atoms
Due to this asymmetry in shape water has a strong property of strong dipole movement that is highly polarized molecule with both positive and negative charges.
It is very cohesive in nature by developing a strong bonding with itself, and also adhesive in nature.
It shows high boiling point as hydrogen- oxygen bond highly polar and
Hydrogen atoms are present at two corners with a tetrahedron shaped which gives water a high polarity.

Which of the following pairs of hormones are secreted by the posterior pituitary gland?
A) Prolactin and growth hormone
B) Melatonin-stimulating hormone and oxytocin
C) Oxytocin and antidiuretic hormone
D) Follicle-stimulating hormone and thyroid-stimulating hormone
E) Prolactin and ACTH
The pairs of hormones secreted by the posterior pituitary gland are C. Oxytocin and antidiuretic hormone.
What is pituitary gland?The posterior pituitary gland is a small, pea-sized endocrine gland located at the base of the brain. It is connected to the hypothalamus by a stalk. The hypothalamus produces two hormones, oxytocin and antidiuretic hormone (ADH), which are stored in the posterior pituitary gland and released into the bloodstream when needed.
Oxytocin is a hormone that is involved in childbirth, breastfeeding, and social bonding. ADH is a hormone that is involved in regulating water balance and blood pressure.

You encounter a new compound that is bright purple and smells of violets. It sticks to surfaces in a way similar to water and can replace water in the running of living cells. You might expect that this new molecule will make
A. hydrophobic bonds.
B. ionic bonds.
C. peptide bonds.
D. covalent bonds.
E. hydrogen bonds.
One encounters a new compound that is bright purple and smells of violets, it sticks to surfaces in a way similar to water, so the new substance might be making the hydrogen bonds that are present in Option E.
What is hydrogen bonding?Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom is covalently bonded to an electronegative atom, and this type of bonding is relatively weak compared to covalent bonds, but it can play an important role in stabilizing the structures of molecules as the new compound sticks to surfaces in a way similar to water, and it is polar and makes the dipole-dipole interaction possible, so the new substance would make the hydrogen bond.
Hence, the new substance might be making the hydrogen bonds that are present in Option E.

If influenza acquired by sharing a drinking glass, then the glass was acting as a:____.
a. vector.
b. reservoir.
c. vehicle.
d. fomite.
Answer: Option C.
Vehicle
Explanation:
It is vehicle because, vehicle is a non living source that serve as an agents or carrier if infectious diseases and that infect or affect many people.
In this case a drinking glass of water is a non living source because it is does not have life and the pathogens that causes influenza are in it and as people begin to share the drinking glass of water, the pathogens are transmitted and they have influenza.

The subunits from which ATP is made are ADP and phosphate.
ATP, meaning Adenosine triphosphate, is a biological molecule responsible for the storage and release of energy in living cells. ATP is structurally made up of three phosphate groups, adenine base and a ribose sugar. However, ATP stores energy for living cells when one phosphate group is added to adenosine diphosphate (ADP) i.e. ADP + Pi = ATP.
