Question 3 of 10
The surface area of a sphere can be approximated as follows:
Surface area = 411/2;
where ris the radius of the sphere;
Ti is a constant that is roughly equal to 3.
Using the simple approximation above, calculate the surface area of a sphere
with a radius of 5 meters.
A. 500 m2
B. 900 m2
C. 3,600 m2
D. 300 m2

Answers

Answer 1

Answer:

D. 300 m²

Explanation:

A sphere is a three dimensional object with a surface which as like that of a ball. A sphere is a set of points that are all at the same distance r from a given point in a three-dimensional space.

The surface area of a sphere is:

Surface area = 4πr²

where r is the radius of the sphere, π is a constant = 3

Given that r = 5 meters, hence substituting into the area equation:

Surface area = 4π(5)² = 4(3)(5)² = 300 m²

B. lichens, trees, hearty shrubs
C. lichens, hearty shrubs, trees

Answers

Answer:

lichens, hearty shrubs, trees

Explanation:

Order:

I-bare rocks,

II-pioneers (mosses, lichen, algae, fungi)

III-annual herbaceous plants

IV-perennial herbaceous plants and grasses

V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.

(please mark me brainliest) :)

Lichens, hearty shrubs, and trees is the correct order in which the organisms return to an ecosystem during primary succession after an area's ecosystem has been wiped out. Thus, the correct option is C.

What is Primary Succession?

Primary succession is the ecological succession which begins in essentially the lifeless areas, such as the regions in which there is no soil or where the soil is incapable of sustaining life where no life form ever existed because of recent volcanic eruption, newly formed sand dunes, or rocks that are left from a retreating glaciers.

The correct order of the Primary Succession is:

Stage I- Bare rocks,

Stage II- Pioneer species such as mosses, lichen, algae, and fungi

Stage III- Annual herbaceous plants

Stage IV- Perennial herbaceous plants and grasses

Stage V- Shrubs, shade intolerant trees, and shade tolerant trees.

Therefore, the correct option is C.

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

Answer:

the Lacey Act

Explanation:

Answer:

> The answer to your query is the Second Answer Choice, or “The Lacey Act”

Explanation:

> The National Park System Act installed the National Park System agency, and ensures that they keep the National Parks safe and as they are intended.

> The Lacey Act prohibits the transportation, trade, selling, or simply possessing, any illegally caught or killed wildlife.

> The EPA (Environmental Protection Agency) makes sure that people and the environment are kept safe from health risks (Pollution, etc). They also enforce regulations on things that may cause harm to people and the environment.

> CITES (Convention on International Trade in Endangered Species) makes sure that there is no INTERNATIONAL trade on endangered species. This is between other countries, and with species that are becoming (or at risk of becoming) exctinct.

> We can match our story to the descriptions and find that it matches up with the second one, or the Lacey Act. Since he had killed a wolf on National Park Territory, and transported and possessed it, he is responsible for breaking the law prohibiting just that.

> Once again, the correct answer is the Second Answer Choice (The Lacey Act).

Geomorphology studies landforms and their evolution. Qualitatively, landforms have been described, and numerically, forces acting on Earth's surface to create landforms and change them. Therefore, it's false.

What is geomorphology?

The scientific study of the formation and development of topographic and bathymetric features formed by physical, chemical, or biological processes occurring at or near the surface of the Earth is called geomorphology.

Geomorphic processes are those that alter the way the earth's surface is arranged and are responsible for the field of study known as geomorphology. Endogenic geomorphic processes include both continental drift and volcanic activity. The processes of mass wasting, weathering, erosion, and deposition fall under the category of exogenic geomorphic processes.

When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants What type of inheritance is it?

Answers

Answer:

Complete dominance

Explanation:

Gregor Mendel (1822 - 1884) was regarded as the "FATHER OF GENETICS" due to his immense contribution to discovering the principles that govern inheritance in organisms. In one of his several experiments, he performed a cross between true-breeding tall plants (TT) and true-breeding short plants (tt).

From this cross, Mendel found out that the F1 generation were all tall. He self-crossed the F1 generation and obtained F2 offsprings in a ratio 3 tall: 1 short. This shows that the tall phenotype allele (T) is dominant over the short phenotype/allele (t), which was being masked in the F1 generation i.e. Tt. This inheritance pattern is called COMPLETE DOMINANCE.

6. What happens when food reaches the stomach?
A. No digestion occurs in the stomach
B. The food moves quickly into the small intestine
C. Juices mix with the food and stomach muscles squeeze it
D. The food is completely digested and is absorbed by tiny blood vessels in the
walls of the stomach​

Answers

Answer:

C) Juices mix with the food and stomach muscles squeeze it.

Explanation:

Gastric juices are added in your stomach to turn your food into small particles that can be gobbled up by cells. Your body contains dangerous level of acids such as HCl but your cell lining in your inner cavities of your stomach prevent acid from burning you form within! Fun :D

So technically the answer is C.

After the food enters your stomach the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents called chyme into your small intestine

¿Cuál de las siguientes opciones son adaptaciones de las plantas al desierto? a) Las raíces superficiales y extensas. b) Las hojas de color amarillas c) El cuerpo carnoso de las plantas d) Las hojas modificadas en forma de espina

Answers

Answer:

a) Las raíces superficiales y extensas

c) El cuerpo carnoso de las plantas

d) Las hojas modificadas en forma de espina

Explanation:

En biología, una adaptación refiere al proceso de cambio evolutivo mediante el cual los organismos de una especie/taxón hacen frente a determinadas condiciones ambientales. Las plantas han desarrollado diferentes adaptaciones en ambientes desérticos a fin de evitar al máximo la pérdida de agua, el factor más limitante en este tipo de ambientes. Las plantas capaces de soportar largos periodos de sequías se denominan xerófitas. En primer lugar, además de servir como una buena defensa contra herbívoros, las hojas en forma de espina le permiten a una planta almacenar agua durante los períodos de precipitaciones. En segundo lugar, las raíces de plantas desérticas pueden disponerse superficialmente con el objetivo de absorber la mayor cantidad de agua posible. En tercer lugar, las plantas suculentas o crasas son aquellas que tienen tejidos carnosos los cuales pueden almacenar agua en sus hojas, tallos o raíces. Durante los periodos de lluvia leve, las suculentas almacenan grandes cantidades de agua para sobrevivir durante la temporada seca (incluso existen especies vegetales que sobreviven solamente durante la temporada húmeda y producen semillas que toleran la temporada seca).
