Which is a density dependent factor?

Answers

Answer 1
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

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

Answers

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 rocks

Fatty acids and lipids

Fatty acids are a component of lipids. Lipids are a diverse group of macromolecules that include fats, oils, phospholipids, and sterols. Fatty acids are the building blocks of lipids.

They are long hydrocarbon chains with a carboxyl group at one end. Fatty acids can be saturated (no double bonds) or unsaturated (one or more double bonds).

When combined with glycerol, fatty acids form triglycerides, the most common type of lipid used for energy storage in organisms.

What is an imbalance in the food chain?

Ecological imbalance occurs when some element (animal or plant) of an ecosystem is reduced in

quantityadded or subtracted.

This change can give rise to chain reactions and directly affect the functioning of the ecosystem.

ou have isolated a previously unstudied protein, identified its complete structure in detail, and determined that it catalyzes the breakdown of a large substrate. You notice it has two binding sites. One of these is large, apparently the bonding site for the large substrate; the other is small, possibly a binding site for a regulatory molecule. What do these findings tell you about the mechanism of this protein

Answers

Answer:

These findings tell us that possibly this protein has an enzymatic function, that is, it is an enzyme.

Its function can be catalytic as well as analytical.

The substrate binding site should be the largest, while the other regulatory site is the smallest.

Explanation:

This happens since hormones regulate their enzymatic activity through inhibitory sites.

They have another smaller binding site, where when an inhibitory molecule binds, it deforms the morphology of the protein causing it to no longer bind to its substrate at the binding site, therefore they inhibit the chemical reaction that is happening within the enzyme. both catalytic and analytical.

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

Answers

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.

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?

Answers

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).

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?

Answers

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.
