Answer:
The correct answer is ''C. Renin-angiotensin system activation causes decreased glomerular filtration rate and fluid retention, which results in increased preload.''
Explanation:
In states of low cardiac output, the renin-angiotensin-aldosterone pathway is activated as a compensatory mechanism, whose objective is to fundamentally modify the peripheral circulation, which operates in conjunction with the activation of the medullary neuro-adrenal system, to maintain blood pressure. These two mechanisms, which are totally different, are closely linked; thus, stimulation of beta-1 adrenoreceptors in the juxtaglomerular apparatus, as a consequence of a high adrenergic output, causes renin output in heart failure. On the other hand, the activation of baroreceptors in the renal vascular bed caused by a reduction in renal blood flow, is also responsible for the release of renin, it occurs in patients with severe heart failure managed with diuretics and salt restriction.
Artesian springs bring pressurized groundwater to the surface through which feature of Karst topography?
streams
caves
fissures
igneous rock
Answer:
The correct answer is D) Fissures
Explanation:
Karst is a topography or landform that is created by the dissolution of soluble rocks beneath the surface by waters from the surface or below.
Fissures are formed when because of earth movements there is the occurrence of a long, narrow opening, in the earth.
Artesian springs refer to the water coming out through these cracks or openings in the earth onto the surface of the Karst topography.

Consider two pure-breeding lines of grapes, P1 and P2. The average diameter of P1 grapes is 1.2 cm and the variance is 0.30 cm2. The average diameter of P2 grapes is 1.6 cm and the variance is 0.56 cm2. The two pure-breeding lines are crossed to produce F1 progeny. Based on this description, which of the following statements is false?
a) VG for F1 is > 0
b) VP for P1 < VG for P2
c) VE for F1 is > 0
d) VG for P1 = 0
e) VG for P2 = 0
Answer:
a)
Explanation:
From the given information:
The avg diameters:
For P1 grapes =1.2 cm
For P2 grapes = 1.6 cm
Their vairance is also given as follows:
For P1 = 0.30 cm²
For P2 = 0.56 cm²
Recall that:
the phenotypic variance VP = genetic variance (VG) + environmental variance VE
As stated that P1 and P2 lines are pure breeding lines, which means that the diameter of the seed in F1 was around halfway between the two parents' and the difference in the F1 was close to the parents'.
This implies that, provided the parent lines exist as pure breeding;
The genetic variation would be absent, indicating that VG is zero.
∴
VP = VE and VG = 0
Now, averaging the results of two pure breeding lines, we have:
[tex]V_E = \Big (\dfrac{0.30 + 0.56}{2} \Big) \\ \\ V_E = \dfrac{0.86}{2} \\ \\ V_E = 0.43 \ cm^2[/tex]
The formula used in estimating F1 genetic variance can be expressed as:
VP = VG + VE
Recall that
VE = VP = 0.43 cm²
∴
0.43 = VG + 0.43
VG = 0.43 - 0.43
VG = 0
Thus, The statement that is false is in Option a.
VG for F1 is > 0

In cats, coat color is an X-linked trait with incomplete dominance. Yellow coat is caused by the allele XT and black coat by the allele Xt. A tortoise cost is caused by the heterozygous condition. What is the correct way to represent the genotype of a male cat with a black coat
Answer:
The genotype of a black male is XtY
Explanation:
Available data:
coat color is an X-linked trait with incomplete dominance.Yellow coat is caused by the allele XTBlack coat by the allele Xt.Tortoise coat is caused by the heterozygous conditionSo,
females genotypes females phenotype
XTXT → Yellow coat XtXt → Black coat XTXt → Tortoise coatmales genotype males phenotype
XTY → Yellow coat XtY → Black coatMales only carry one X chromosome, so they can only be either black - XtY- or yellow -XTY-.
Females are the only ones that can express the tortoise coat.
The correct way to represent the genotype of a male cat with a black coat - XtY
We know that,
In cats, coat color is an X-linked trait - it means it is influenced by the X allele onlyIn cats, coat color is shows incomplete dominance - it means if corresponding alleles present together they will show an intermediate coat color.the allele XT - Yellow coatthe allele Xt - black coatXTXt (heterozygous) - tortoise coat (incomplete dominance)In X linked traits heterozygous conditions are not possible in males as they have only one X allele and the other is Y allele.So,
Female cats genotype would be:
XTXT - female cat with yellow coatXTXt - female cat with a black coatXtXt - female cat with tortoise coatMale cats genotype:
1. XtY - black coat male cat
2. XTY - yellow coat male cat.
Thus, The correct way to represent the genotype of a male cat with a black coat - XtY

why the solute can't move from higher concentration to lower concentration?
Answer:
yes, so when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.

Rain cannot occur until ____?
A. the air becomes saturated with water vapor
B. the water vapor exceeds an absolute humidity of 80 ppm
C. a warm front meets a cold front
D. clouds reach an altitude of 1000 ft
Answer:
A. the air becomes saturated with water vapor
Explanation:
The saturated water vapor air forms clouds ( nimbus clouds ) which hold that vapour at a low pressure
Answer:
A. The air becomes saturated with water vapor
Explanation:
Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew point is the temperature at which condensation happens.

Capillaries are very thin, narrow blood vessels that allow for the transfer of oxygen, carbon dioxide, and nutrients. The image shows
how normal red blood cells and sickle-shaped red blood cells flow through a capillary,
Use information in the image to describe two ways that the sickle cell gene mutation affects the ability of red blood cells to perform
their normal function
Answer:
less packaging of oxygen
Explanation:
normal RBC (red blood cells) have a large surface area for oxygen packaging due to its biconcave shape but when mutation occurs the RBC being produced by the short bones is sickle shaped reducing surface area of haemoglobin exposed, responsible for packaging oxygen so tissues don't get right amount of oxygen

Answer: soil type
Explanation:
All of the following affect groundwater contamination except Soil type.
What is Soil type?In soil science, a soil type is a taxonomic unit. A distinctive soil type is made up of all soils that have a certain set of well-defined features in common.
The phrase "soil type" refers to the study of soil classification, which is concerned with the orderly classification of soils. Every soil on the planet is a particular soil type.
The majority of soil types in hierarchical soil classification schemes are in the higher or intermediate level. Typically, a soil type can be further broken down into subtypes, and in many systems, multiple soil types can be joined to form higher category entities.
Therefore, All of the following affect groundwater contamination except Soil type.

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPa, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl
Answer: hello your question is in complete below is the complete question
A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa
answer : 5.88 GPa
Explanation:
Fiber reinforced composite containing e-glass fibers
E for the glass ( Ei ) = 72 GPa
E for the epoxy ( Em ) = 2.4 GPa
Determine the Elastic modulus of a composite containing 5% fibers
percentage of glass = 5% = Vi = 0.05
∴ percentage of epoxy = 95% ; Vm = 0.95
using the relation included in the question
Ecl = Ei Vi + Em Vm
= ( 72 * 0.05 ) + ( 2.4 * 0.95 )
= 3.6 + 2.28 = 5.88 GPa

Explanation:
One conclusion drawn from the experiment was that life span differences were independent of reproductive investment. If that is the case, then which of the following statements is true? Females that exhibited catch-up growth and produced many eggs had longer life spans than females that exhibited catch-up growth and produced few eggs. Females that exhibited catch-up growth and produced few eggs had longer life spans than females that exhibited catch-up growth and produced many eggs. Females that exhibited slowed growth and produced many eggs had longer life spans than females that exhibited slowed growth and produced few eggs. Females that exhibited slowed growth and produced few eggs had longer life spans than females that exhibited slowed growth and produced many eggs. Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Answer:
The correct answer is - Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Explanation:
According to the question, the life span differences were independent of reproductive investment, on the basis of this experiment, it is clear that the sexual gametes or egg which is a reproductive investment are independent of the lifespan of a female.
The life span of females could be slow growing or not but it will not affect the production of the gametes or eggs. Eggs production is dependent upon hormones produced.
