Answers

Answer:

Cuando la célula madre se divide varias veces de forma consecutiva y los núcleos se rodean del citoplasma dentro de ella, es una reproducción tipo: esporulación.

Explanation:

En la reproducción asexual, un solo ser origina nuevos individuos iguales entre si e iguales a su progenitor. Este tipo de reproducción es común en ciertos invertebrados, en las bacterias y en los protozoarios. La esporulación es uno de los tipos de reproducción asexual, esta consiste en varias divisiones del núcleo que se envuelve de fragmentos citoplasmáticos, originando muchos descendientes genéricamente idénticos. Dicha reproducción permite la formación de esporas y la liberación de las mismas cuando las paredes de la célula se rompen. Se observa en ciertas especies de protozoarios.

Which particle, protons, neutrons, or electrons, has the LEAST mass?

Answers

Answer:

Electrons are much smaller in mass

Explanation:

Although similar in mass, protons are positively charged, while neutrons have no charge. Therefore, the number of neutrons in an atom contributes significantly to its mass, but not to its charge. Electrons are much smaller in mass than protons, weighing only 9.11 × 10−28 grams, or about 1/1800 of an atomic mass unit.

Luis created a clay model of Earth. He used a toothpick to represent Earth's axis. The toothpick was stuck horizontally through the center of the Earth model, slightly to the side of each pole. He then used a flashlight to shine light on part of the Earth. Finally, he used the toothpick to spin the model Earth. What do you think Luis is trying to model?

Answers

Answer: Earth's rotation

Explanation:

Luis was most trying to model the Earth's rotation. As you know the earth rotates around it's axis once every 24 hours and this is why we have different times in the day because the sun shines on different parts of the Earth as it rotates.

Luis used the flashlight as the sun and when he used the toothpick to spin the model of earth, the model would represent earth rotating around its axis.

Answer:I think it’s earths day and night

Explanation: it says that he is flashing a light to one side of earth so I think he’s trying to show the day and night cycle

it affects the weather.

Answers

Answer: Water cycle is a complex cycle of water in which the water is changed into various forms like solid, liquid, and gases.

Explanation:

In the higher atmosphere the water vapors condense to form clouds and they club to form the ice crystals. These ice crystals when strikes on the ground as precipitate or ice pellets again changes its form from solid to liquid rain. The precipitation can be in the form of rain or wet snow. The rain stops when the concentration of water vapors in the higher atmosphere reduces and sun may come out.

The water cycle is a complex cycle of water in which the water is changed into various forms like solid, liquid, and gases.

Define the water cycle?

The water cycle illustrates the continuous action of water within the Earth and atmosphere. It is a complicated system that has many different processes.

Liquid water evaporates into water vapour, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Thus, water is changed into various forms like solid, liquid, and gases.

What is the complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT?
A. TAC CCG GTA
B. UAC CCG GUA
C. ATG GGC CAT
D. CGA AAT AGC

Answers

The answer to this is A. The complementary strands are A-T, T-A, G-C, C-G, and U-A

The complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT is TAC CCG GTA. Thus, the correct option for this question is A.

What is DNA replication?

DNA replication may be defined as a type of biological process through which two identical replicas of DNA form from one original DNA molecule. This process makes a copy of the DNA in a cell is made before the cell divides.

When it comes to the complementary strand of DNA, either of the two chains makes up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.

For example, if Adenine A is present in the parental DNA, then it should be complementarily bounded to the thymine and vice versa. Similarly, if Cytosine is present in the parental strand of DNA, then it should be complementarily bounded by guanine and vice versa.

Therefore, the correct option for this question is A.

How is the age distribution pattern of the Hawaiian Islands - Emperor Seamount chain explained by the position of the Hawaiian hotspot? Explain using evidence and reasoning.

Answers

Answer:

Find the explanation below.

Explanation:

The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.

This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.

In camellia plants, flower color is controlled by a single gene with codominant alleles. A camellia plants with red flowers (RR) is crossed with a camellia plant with white flowers (WW). What are the expected phenotypes of the offspring of this cross?
A.
All will have red flowers.
B.
Half will have red flowers and half will have white flowers.
C.
All will have both red and white flowers.
D.
All will have pink flowers.

Answers

Answer:

The answer is; c

It is important to distinguish between codominance and incomplete dominance.

In incomplete dominance, the two alleles blend with each other in phenotype  giving offspring with intermediate phenotypes, hence offspring would produce pink flowers, in this case.

In codominance, both alleles are simultaneously expressed in phenotype in the offspring. Therefore flowers, in this case, would exhibit both red and white colors.

At 1 the time, the hundreds of millions who watched this historic event likely thought it marked the beginningof a bold new kind of exploration. Perhaps they thought they would soon hear more messages from outer space. Maybe they envisioned that by the turn of the century someone would walk on the surface of Mars. Now, though, more than 40 years later, its robotsnot astronautswho are making most of the voyages beyond Earths atmosphere. Robotic space exploration does have some advantages. However, there are many reasons why we should make sending more people into space a priority.-Beyond the Program-The capabilities of the space probes and rovers we now use would have been the stuff of science fiction 2 just a few short decades ago. Like any other machines, though, they have one major weakness. Theycan do only what they are programmed to do. They cannot make a distinction between unusual and expected observations. They cannot reason. They cannot think. A human scientist who identified a curious specimen on Mars would likely concentrate on finding out everything possible about it. The unthinking robot would probably treat it as just another sample.-Efforts Yield Results-One of the arguments in favor of using robots to explore space is that machines can go places humans cannot. This may be true, but lets consider the other side. Maybe the reason astronauts are not able to go to these places yet is that we arent putting enough effort into figuring out how to meet their complex needs during prolonged space missions. Humans have proven time and again that they are able to solve problems that may have seemed impossible at first. There is no reason to assume that the challenge of sending people to Mars, Jupiter, or Neptune and getting them back home safely would be any different.-Costs and Benefits-Humans, as living things, have many needs that robots do not. Giving astronauts what they require to stay 4 healthy in space naturally makes these kinds of missions more expensive than ones that use robots. Its vital to weigh these increased costs against the benefits. If sending one human crew to Venus could advance our knowledge of the universe as much as three robotic space missions could, even a much higher cost would be justified.Keeping the Dream Alive It is said that the idea of traveling into space captures the imagination. For most, though, its not an image 5 of a small vehicle rolling across the surface of Mars that inspires awe and wonder. Its the notion thatone daypeople from Earth will explore distant worlds that are literally millions of miles away from our home planet. true or false? all elements are compounds What are some of the postmodern elements in play, Killing Time?the use of formal language, pop culture references, ambiguous endingthe use of slang, pop culture references, ambiguous endingthe use of formal language, nontraditional gender roles, ambiguous endingthe use of slang, traditional gender roles, ambiguous ending How did the United States government limit peoples freedoms during World War I?
