The carrying capacity for a population of frogs in a rainforest ecosystem is 840 frogs, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for 212 frogs?
4 frogs per year
29 frogs per year
158 frogs per year
314 frogs per year
Answer:
4 frogs per year is the answer
In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K).
Formula used: dN/dT= rN{1-N/K}
Given: k= 840 frogs
N= 212, r= 1 year
To find: r=?
Solution:
putting value in equation:
dN/dT= rN{1-N/K}
dN/dT = 1 x 212 {1-212/840}
so, dN/dT= 158.57 ( approx)
Final answer: The correct option is (c)
158 frogs per year
Thus, we can conclude that 158 frogs per year will be the population of frogs.

Answer:
because the precaution is skin shade by the patient should be burned away and not be directly test
Answer:
People suffering from chickenpox should not be in sunlight because the skin is more susceptible to heatstroke. The virus stays for a long time in the body, even after the symptoms are gone. Hence, it is recommended to burn it.

What is the structure of a Triglyceride?
A. A glycerol head with 3 fatty acid tails
B. 3 Glycogen heads connected to a Hydroxyl tail
C. 3 Hydroxyls connected to a glyceride
D. A glycerol head with 2 fatty acid tails
Answer:
A. A glycerol head with 3 fatty acid tails
Explanation:
One glycerol attached to 3 fatty acids each
The structure of a Triglyceride is a glycerol head with 3 fatty acid tails. Hence the correct option is A.
The structure of a triglyceride consists of a glycerol molecule bonded to three fatty acid tails. Glycerol is a three-carbon alcohol with a hydroxyl group attached to each carbon, while fatty acids are long hydrocarbon chains with a carboxyl group at one end. Through a condensation reaction, the hydroxyl group of each glycerol molecule combines with the carboxyl group of a fatty acid, resulting in the formation of an ester bond.
This process is repeated three times, with each fatty acid binding to a different carbon of the glycerol molecule, thus forming a triglyceride. The three fatty acid tails provide energy storage and insulation properties, while the glycerol molecule serves as a backbone for their attachment. Triglycerides are the main storage form of fat in animals and plants.
Hence the correct option is A.

Maintaining a rich variety of genetic material that can lead to discoveries useful for humans can be ensured by preserving biodiversity. Explanation: Options for this question are: Preserving biodiversity .Hope this is fine for youThis Roman snail, this cuttlefish, and this mussel have similarities and differences in their body structures. What does the information about these structures tell you about the ancestors of these species
Complete question:
This Roman snail, this cuttlefish, and this mussel have similarities and
differences in their body structures. What does the information about these
structures tell you about the ancestors of these species?
a) None share an ancestor population because different species cannot share an ancestor population. It is a coincidence that these species have some of the same body structures.
b) The Roman snail and the cuttlefish share an ancestor population, but they must not share an ancestor with mussels because mussels have no radula.
c) All three species share an ancestor population, but Roman snails and
cuttlefish share a more recent ancestor population. This is why they share
the radula structure.
d) We cannot make observations of ancestor populations from the past. It is
impossible to explain ancestors with only the information about the body
structures of different species.
Answer:
The correct answer is option C. All three species share an ancestor population, but Roman snails and cuttlefish share a more recent ancestor population. This is why they share the radula structure.
Explanation:
The three species belong to the mollusk phylum, and to the placophore group.
Each of them belongs to a different class.
The Roman snail belongs to the Gasteropod class, The cuttlefish belongs to the Cephalopod class, The mussel belongs to the Bivalve class.The tree classes share a common ancestor from which all the placophores evolved. Among them, we can mention the monoplacophore, gasteropod, cephalopod, bivalve, and scaphopods. Three branches diverged from this common ancestor. The first one originated the monoplacophore. The second one originated the common ancestor of gastropods and cephalopods. And the third one originated the common ancestor of bivalves and scaphopods. The tree-mentioned species inherited the mantle and the radula from their foreign common ancestor. But later in time, individuals that originated bivalves lost the radulla. This is why the three species have a mantle, but only gastropods and cephalopods have a radula. When each of these classes evolved, they developed their own traits,
Gastropods → muscular foot used for moving Cephalopods → pallial cavity for swimmingBivalves → byssal threads to attach to the rocksYou will find an image in the attached files that will help you understand this explanation.

El efisema pulmonar,provocado princioalmente por el consumo de cigarro, es una lesion que genera destruccion de los alveolos y, por lo tanto, zonas en las que no se produce el intercambio de gases ¿que consecuencias puede tener esta lesion en el organismo?
Answer:
El enfisema pulmonar disminuye la cantidad de tejido pulmonar, disminuyendo de este modo la cantidad de oxígeno que llega a la sangre (hipoxemia). El enfisema está asociado a diferentes trastornos incluyendo infecciones respiratorias recurrentes, pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores.
Explanation:
El enfisema pulmonar es una enfermedad causada por la destrucción de los alvéolos pulmonares la cual está asociada a un aumento en la dificultad para respirar. Las principales causas de esta enfermedad son la exposición continua al humo del cigarrillo y otras sustancias nocivas para la salud, como así también a contaminantes presentes en la atmósfera. El enfisema pulmonar va progresivamente destruyendo las paredes alveolares pulmonares y los vasos sanguíneos que las recorren, disminuyendo así la elasticidad pulmonar, aumentando la proporción de aire que recorre los pulmones y de este modo también aumentando la distensibilidad pulmonar. Esta enfermedad disminuye la capacidad de oxigenar la sangre, generando una sensación constante de falta de aire (disnea) y cuadros progresivamente más severos de hipoxemia. Cuando el enfisema pulmonar se encuentra en grado avanzado, la única opción viable es el reemplazo del órgano dañado mediante un trasplante pulmonar. El enfisema puede estar asociado a infecciones respiratorias recurrentes (resfriados, gripe), pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores (tobillos, pies y piernas).

gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answer:
wind generated power plants. they have the lowest efficiency because it is not always windy and the wind varies everyday, thus the wind turbines will generate different amounts of electricity each day. They also can be very noisy and cause noise pollution. Wind Plants need good land place and these are mainly found in rural areas far from the city that the electricity is needed.

Can someone please help me with these two:
1. Blood is at it's highest pressure just when it leaves the heart. Why do you think so?
2. The blood in an artery flows faster and at higher pressure than blood in veins. Why so?
Answer:
1.Blood pressure can be defined as the pressure of blood on the walls of the arteries as it circulates through the body. Blood pressure is highest as its leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries).
2. The more rounded the lumen, the less surface area the blood encounters, and the less resistance the vessel offers. Vasoconstriction increases pressure within a vein as it does in an artery, but in veins, the increased pressure increases flow.
