2. Why is an amniotic egg an evolutionary leap for reptiles? 1It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. 2 It allowed for many offspring to be made at the same time. 3 It allowed female reptiles to lay their eggs and leave the young to fend for themselves. 4It allowed for asexual reproduction by females only.​

Answers

Answer 1

It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. Option 1.

Evolutionary advantage of the amniotic egg

The amniotic egg enables organisms to live their lives entirely away from water.

Prior to the evolution of the amniotic egg, the egg being laid by animals cannot survive on land. Also, the fertilization of the eggs requires water.

The amniotic egg is equipped with features that enable it to survive conditions on land.  The external shell and the amniotic fluid protect the embryo from mechanical damage and dehydration. Gaseous exchange and waste excretion of the embryo are taken care of by the allantois and the chorion.

What do Doodle’s repeated pleas of “Don’t leave me” foreshadow?

What type of character is Doodle?

He is a rounded character because as the narrative progresses and he ages, he picks up numerous flexible and eccentric traits including tenacity, frailty, being underestimated, imagination, and dependency. Because she is only identified by a few characteristics, Aunt Nicey has a flat personality.

Scarlet ibis and Doodle are similar. He is despised by his family because he is clumsy. They anticipated that he wouldn't survive. The scarlet ibis, which likewise exhibits extreme weakness like Doodle, serves as a metaphor for him.

3 Describe two pieces of evidence that show that plants cannot make their own food without light.
4 Starch tests show where photosynthesis has taken place. What can you conclude using the evidence from test 1?.
à5 What does the evidence from test 3 show? ​

Answers

1. Animals depend on plants to keep them alive is Plants are producers  they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.

They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.

2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata

3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.

The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.

How are leaves tested for starch?

The rate of cellular respiration and photosynthesis can increase or decrease because of different factors.

Explain how either the rate of cellular respiration or the rate of photosynthesis can be increased and decreased. Be sure to include details of specific reactions in your answer.

Answers

The main environmental factors that affect photosynthesis are: light, CO2 and temperature. Also, the availability of water and nutrients are important factors.

How to increase the rate of photosynthesis?

Plants kept under ideal conditions of luminosity and carbon dioxide concentration increase the rate of photosynthesis as the ambient temperature increases, up to close to 40°C. Above this temperature limit, there will be a drastic reduction not only in photosynthesis, but also in most vital reactions.

The photosynthetic rate, that is, the intensity of photosynthesis that the plant performs, can be changed by the amount of light it receives. The greater this light radiation, the greater the photosynthetic rate, if there is no other factor such as temperature or water availability limiting the process.

What do we call Earth's orbit around the Sun?
intergalactic movement
Earth's revolution

Answers

Answer:

Earth's revolution

How do we know that the earth orbits the sun?

If you study the stars and know where all the planets on the solar system are, you will notice that those stars alternate their motion in the sky, which means they do not orbit the Earth. In fact, the word "planet" originally means tricky star, suggesting that those "stars" did not behave like other normal stars.

The theory of universal gravity cannot be denied, since we are able to send satellites to outer space and have them orbit our plant. In fact, we are able to derive equations to figure out how fast the satellite need to orbit around the earth in relation to how high above the surface of the earth it is. The same mathematics that derived said information had also been used to derive the geosynchronous height from the Earth, which is the height at which a satellite orbiting the Earth, with the necessary speed to stay in circular orbit (not elliptical orbit), matches the Earth's rotation about its axis. Geosynchronous satellites are used for T.V. broadcasting and many other applications.

The formula for universal gravitation is GMm/r2, which means that the force of gravity on an object by another object are proportional to the masses of both objects, and inversely proportional to the square of the distance between them, and this proportion is multiplied by a constant G. It makes greater sense that the Earth revolves around the Sun, and not the other way around, because the mass of the Earth is way too small to apply a force strong enough to create a large enough acceleration on the sun to keep it in orbit around the Earth. If the Earth had enough mass to cause that huge of a gravitational force, then the moon will not remain in orbit around the Earth, but will fall closer the Earth and hit the Earth.

What is the revolution of a planet?

The process through which a planet, let's say the earth, revolves around a huge mass that is significantly larger than the planet, such as the sun or any star. And the gravity between the two bodies is what causes this process to occur.

It is expressed as mass per unit volume.  

Density (abbreviated D or ρ) is a mathematical concept.

ρ=m/V, where

ρ is the density, m is the object's mass, and V is the object's volume.

Given the above, what is the density of the solid?

From the above information:

ρ = 25/50ρ

ρ= 0.5

One of an object's most significant and practicable physical characteristics is density.

Densities are frequently used to distinguish between pure materials as well as to describe and infer the composition of various types of mixes.
