A) Grass and ferns are the producer. Rabbits, Grasshoppers and caterpillars are the primary consumers. The robin, foxes and hawks are the secondary consumers. B) If the hawks died, the rabbits and foxes would over-populate the area. The rabbits would over graze the ferns and make it harder for the caterpillars to feed. The foxes would over graze on the robins, potentially wiping them out. This would allow the grasshopper to grow out-of-control leading to the loss of the second food source for the caterpillars. Eventually, the ecosystem would crash. C) The higher up the food pyramid you go, the smaller the population has to be. Foxes are higher up than caterpillars so they have to have a smaller population. D) The hawks has to have the smallest population.

Assume that the left ventricle of a child's heart has an EDV=90mL, and ESV=60mL, and a cardiac output of 2,400 mL/min. His SV is
Sliva [168]

Answer:

SV = 30 ml/ beat.

HR = 80.

Explanation:

The formula to calculate SV is as follows:

SV = EDV- ESV.

Here EDV = 90ml (end diastolic volume), ESV = 60ml (end systolic volume) ans SV is stroke volume.

SV = 90-60

SV = 30ml/beat.

The formula to calculate HR is as follows:

HR = CO/SV

Here, HR is heart rate, CO is cardiac output = 2,400 ml/min and SV is stroke volume = 30ml/beat

HR = 2,400/30

HR = 80.

Thus, the SV is 30ml/best and HR is 80.

In humans, pigmented skin is dominant to non-pigmented skin (albinism). What is the genotype of an individual of albinism?
Rom4ik [11]
I had to look for the options and the answer for this would be HOMOZYGOUS RECESSIVE. Basing on the description above regarding pigmented skin called albinism, the genotype of this kind of individual is homozygous recessive. Hope this answers your question.

What are cones in the eye
Varvara68 [4.7K]

They are a type of photoreceptor in the retina responsible for color vision. There are three types of cones; blue, green and red mainly packed in the fovea.  The other type of photoreceptor is the rods responsible for black and white vision and are mainly located in the peripherals of the retina.  Rods can perceive dim light, unlike cones.

What is BMPER? Did its discovery come from basic or applied science? Explain your reasoning fully.
Mekhanik [1.2K]

BMPER  can be described as a kind of protein that can be found in some organism and there are  BMPER gene present in it as a result of encoding.

The answer to the second question is Yes, this is because the discovery come from basic or applied science since we know that science is based on evidence after many research, and  BMPER can be proved with evidence.

<h3>What is BMPER?</h3>

It should be noted that Bone morphogenetic proteins which is been known as the BMPER  can be seen in   embryonic  which is very common in adult blood vessel formation   and this is been studied alot by the researcher.

BMPER  serves as a  differentially expressed protein  that can be found in the  embryonic endothelial precursor cells.

It should be noted that there can be some interaction between  BMPER and BMPs.

In conclusion, BMPER is also seen as a protein and this can as well be seen in  humans which is been encoded through the  BMPER gene.
