Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

Connell’s results led him to conclude that Chthamalus’ realized niche is smaller than its fundamental niche because of interspecific competition with Balanus. But what if competitive exclusion were not the explanation? What if Chthamalus’ and Balanus’ respective niches were a result of niche differentiation instead? Niche differentiation occurs when two species with overlapping niches change over time in a way that reduces their niche overlap, and thus reduces their competition for resources.
Answer:
Both realized niche and fundamental niche are similar in size.
Explanation:
If Chthamalus’ and Balanus’ respective niches were a result of niche differentiation so we can say that Chthamalus’ realized niche is not smaller than its fundamental niche. It will be of the same size because of no interspecific competition with Balanus. The whole fundamental niche is considered the niche of the Chthamalus' alone due to no competition with Balanus' for resources present in the ecosystem.

In a population of 100 people, 30 have brown hair and 70 have black hair. What is the Relative Frequency for Black hair?
Answer:
0.7
Explanation:
Given that in statistics, the Relative Frequency is the Frequency of the class divided by Total.
Hence, in this case, the Relative Frequency of black hair is the Frequency of black hair divided by the Total.
Hence, we have 70 ÷ 100
=> 0.7
Therefore, the correct answer is 0.7 Relative frequency.

When graphing data, what will make it
more precise?
A. using larger units
B. making it cover most of the graph
C. using a bar graph
D. connecting all the points plotted
Answer:
A. using larger units
Explanation:
Graphs can be used to display large amounts of numerical data and to portray the relationships between numerical values of different variables
When graphing data, what will make it more precise would be to ensure that it covers most of the space on the graph sheet. The correct option would, therefore, be B.
Using larger units may result in inaccurate plotting of small variablesNot all data can be represented as a bar graphConnecting all the points plotted has no bearing on the precision of a graphMaking your graph to cover, at least, 2/3 of the graph space will ensure that your plots are visible and lead to a more precise graph.

does this an suggest evolutionary relationship? explain how these embryos can be used as evidence of a common ancestor between each of these six organism
Answer:
Examination of vertebrate embryos reveals that during corresponding stages of early development,
the embryos appear to be very similar. For example, all vertebrate embryos pass through stages in
which they have gill pouches. The pouches eventually develop into the gill apparatus in fish; in laterevolving vertebrates that do not have gills, the gill pouches undergo further refinement and develop
into structures associated with the head and neck. Similarly, all early vertebrate embryos have tails,
which persist in some animals but regress during the later stages of development of humans. Thus,
the individual development of an animal occurs through a series of stages that paint a broad picture
of the evolutionary stages (phylogeny) of the species to which it belongs.
"Ontogeny recapitulates Phylogeny", Haeckel
Explanation:
sure po ito
Examination of vertebrate embryos well-known shows that in corresponding levels of early improvement, the embryos appear very similar.
For example, all vertebrate embryos by skip thru levels in which they have got gill pouches. The pouches subsequently turn into the gill equipment in fish; in later evolving vertebrates that don't have gills, the gill pouches go through similar refinement and develop into systems related to the pinnacle and neck. Similarly, all early vertebrate embryos have tails, which persist in a few animals however regress at some point in the later levels of improvement of humans.What is ontogeny recapitulates phylogeny?These scientists claimed that ontogeny recapitulates phylogeny (ORP). This word shows that an organism's improvement will take it thru every one of the personal levels of its evolutionary history, or its phylogeny.
Thus, the man or woman improvement of an animal happens thru a chain of levels that paint an extensive picture of the evolutionary levels (phylogeny) of the species to which it belongs.

A small creek runs through a mature forest, keeping the soil around the creek damp all year. A variety of ferns and several flowering plants thrive in this shady, moist area. Along the higher ground above the creek, many species of flowering plants that need less water grow. If a farmer diverted the creek to water his fields, causing the creek to dry up, what would be the most likely long-term consequence for the ferns and angiosperms in the forest?
The ferns would outcompete the angiosperms in the forest since they can tolerate a wider range of moisture conditions than angiosperms.
The angiosperms and the ferns would not be affected since their thick, waxy cuticle coverings would protect them from drying out.
The angiosperms would outcompete the ferns since their sperm do not need moist conditions to get to their eggs as ferns do.
The ferns and angiosperms would begin to produce spores instead of seeds since the spores are better able to survive dry conditions.
Answer:
The ferns would outcompete the angiosperms in the forest since they can tolerate a wider range of moisture conditions than angiosperms.

Explain and illustrate using chemical pathways how excessive alcohol intake can lead to; 1.Hypoglycemia
Answer: Alcohol can influence the blood sugar levels causing hypoglycemia.
Explanation:
Hypoglycemia is a condition in which the body experiences low blood sugar levels. Alcohol abuse can be one of the reasons for hypoglycemia. The occasional drinkers are affected negatively by this. It increases the secretion of insulin hormone which is a hormone necessary for keeping a balance of blood sugar levels in the body. The excess secretion of insulin can lead to decrease in blood sugar concentration and resulting in hypoglycemia. This can lead to type 1 diabetes.
