Answer:
light intensity, carbon dioxide, and temperature
Explanation:
light Intensity because it depends how much sunlight the plants absorb
carbon dioxide because plants need a lot of CO2 to produce photosynthesis
temperature because it shouldn't be too cold or too hot, it should be room temperature

convention cells hbnmb,
Answer:
convention cells
Explanation:
In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.

Please explain how shade-adapted plants tend to differ from sun-adapted plants, using the terms: specific leaf area, dark respiration, root mass fraction, leaf lifespan.
Answer:
Thickness and number of chlorophyll.
Explanation:
Shade-adapted plants differ from sun-adapted plants due to many characteristics such as thickness and number of chlorophyll. Sun leaves are more in thickness than shade leaves because they develop longer palisade cells. Shade leaves generally have more chlorophyll as compared to sun-adapted plants. Specific leaf area and root mass fraction of Shade-adapted plants are higher as compared sun-adapted plants due to large number of chlorophyll to harvest more sunlight for photosynthesis. Dark respiration is higher in sun-adapted plants when there is darkness as compared to shade-adapted plants which produce food in no direct sunlight.
5 The systolic blood pressure reading of 140-159 the systolic blood pressure reading of 140 - 159 is what stage of Hypertension?
A Stage 2
B Stage 1
C Stage 3
D High Normal
Answer:
B. Stage 1
Explanation:
Systolic blood pressure is less than 120 mm Hg and Diastolic less than 80 mm Hg so it is considered as normal. Pre-Hypertension occurs when the Systolic blood pressure is 120 - 139 and Diastolic pressure is 80 - 89. Stage 1 Hypertension is considered when the Systolic blood pressure is 140 - 159 and Diastolic blood pressure is 90- 99. If the Systolic blood pressure is greater than 160 it is considered as Stage 2 Hypertension.

Two polypeptides, X and Y, have similar tertiary structures. X normally exists as a monomer while Y exists as a tetramer, Y4. What differences might be expected in the amino acid composition of X versus Y
Answer:
Due to number of amino acids.
Explanation:
The main differences might be expected in the amino acid composition of X versus Y because the X polypeptide is made up of one smaller unit of amino acid while on the other hand, Y polypeptide is made up of four smaller units of amino acids. The name of X is monomer which means composed of one amino acids while Y exists as a tetramer which means it has four amino acids. So we can conclude that the main difference between X and Y is the presence of number of amino acids.
Amino acids are organic compounds that are formed of amino, carboxylic and a side group. They bond to form protein structures.
The amino acids fold in various structures like primary, secondary, tertiary etc. The basic contrast in an amino acid arrangement of polypeptide X and Y is that the X is made of small units while Y is made of larger units.
X polypeptide is a monomer that is it only has one unit of amino acid while Y is a tetramer that is it has four-unit of amino acids.
Therefore, the number of amino acids is the main distinction between X and Y tertiary structures.

Answer:
I believe the answer would be B because if I'm sure the bottom is grain which has higher levels in grain and glucose I believe and that doesn't produce energy . The second level is meat and that has protein which give us strength.
What does the flagella do in a euglenoid?
Answer:
Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir.
In fruit flies, the phenotype for eye color is determined by a certain locus. E indicates the dominant allele and e indicates the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit fly produced the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F1 Generation 0 45 55 0 1
The wild-type and white-eyed individuals from the F1 generation were then crossed to produce the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F2 Generation 23 31 22 24 0
Required:
a. Determine the genotypes of the original parents (P generation) and explain your reasoning.
b. Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes.
Answer:
The genotypes of the original parents are
Male: X⁺Y Female: X⁻X⁻The Chi-square analysis leads us to accept the prediction of the parental genotypes.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
(a) The genotypes for the original parents (P generation) are
Male: X⁺Y
Female: X⁻X⁻
(b) The prediction of the parental genotype is accepted by the Chi-squared test analysis.
What is the eye color pattern in fruit flies?Drosophila Melanogaster is a fruit fly with abnormally big, brightly colored eyes.
The range in color from red to sepia to white reveals a lot about the genetic makeup of the fly.
(a) E = + ⇒ Dominant allele coding for wild-type eyes
e = - ⇒ Recessive allele coding for white eyes
Now, Crossing the : male wild-type with a female white-eyed
(Parental) = X⁺Y x X⁻X⁻
(Phenotype) = wild white
(Gametes) = X⁺ Y X⁻ X⁻
(Punnett square) = X⁺ Y
X⁻ = X⁺X⁻ X⁻Y
X⁻ = X⁺X⁻ X⁻Y
In (F1)generation = 2/4 = 1/2 = 50% of the progeny are expected to be wild-type females.
And 2/4 = 1/2 = 50% of the progeny are expected to be white-eyed males.
Thus, the percentages are almost 50:50, as the expected ones.
So, the genotypes of the original parents are
Male: X⁺Y
Female: X⁻X⁻
(b) Using Chi-squared test :
Observed fruit fly type:
Wild Type Male - 25
Wild Type Female - 31
White-eyed Male - 22
White-eyed Female - 24
Expected fruit fly type:
Wild Type Male - 25
Wild Type Female - 25
White-eyed Male - 25
White-eyed Female - 25
Now, chi square [tex]= \sum\dfrac{(O- E)^2 }{E}[/tex]
By putting numbers in the formula, we are getting
Wild Type Male - 0.16
Wild Type Female - 1.44
White-eyed Male - 0.36
White-eyed Female - 0.04
Now, X² = 0.16 + 1.44 + 0.36 + 0.04 = 2
Critical value = 7.82
X² (2) < critical value (7.82)
Thus, this is the evidence to accept the given hypothesis.
