DNA replicates twice during meiosis
true or false?
Answer:
Meiosis consists of one round of DNA replication and two rounds of chromosome segregation.
Explanation:
DNA replicates twice during meiosis. Meiosis consists of one round of DNA replication and two rounds of chromosome segregation. Therefore, this statement in false.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

To what extent were the middle ages a time of globalization?
Answer:
The Middle Ages had processes similar to globalization, but in truth, they were more of a regionalization.
Explanation:
The Middle Ages were a period where there were several attempts for globalization, with varying success. Now on one side, we can say globalization because of the amount of knowledge the people had about the world, but in reality, it was more of a regionalization.
We can see these processes occurring in both the Old World and the New World. In the Old World, it was more prominent. The biggest impact of some form of globalization had the Mongol Empire, as it occupied the most territory, resurrected the Silk Road, and prompted trade and exchange of ideas and technology over most of Eurasia, but also Northern Africa.
In the New World, there was something similar going on with the rise of the Incan Empire. It connected both sides of the Andes and prompted trade between the interior of the continent and the Pacific coast. Also, it seems that there has been some connection with Mesoamerica as well, which will make it on an even large scale, but still only regionally.
what is plasmid? How is a plasmid used in gene splicing?
Answer:
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
A gene is spliced by assembling different gene segments and DNA sequences into a product called a chimera. Scientists join these snippets in a circular piece of DNA called a plasmid. Scientists use a complex process to clone genes from an organism's DNA.

what is the difference between phototropism , gravitropism , hydrotropism , and thigmotropism
Answer:
https://brainly.in/question/6314438
Geo- means earth, tropism is movement. Geotropism is what makes roots grow toward gravity and shoots grow away from gravity, so that plants are oriented correctly in the ground.
The response of plants or animals towards light is called phototropism.
When the response is towards the light, it is called positive phototropism.
And when the response is away from the source of light, it is called negative phototropism.
For example, we see plants bending towards sunlight. It is actually their response towards light and is called positive phototropism.
Thigmotropism is the directional response of a plant organ to touch or physical contact with a solid object. This directional response is generally caused by the induction of some pattern of differential growth. This phenomenon is clearly illustrated by the climbing tendrils of some plants, such as the sweet pea

list three reasons why phytoplankton cannot survive at a hydrothermal vent
Answer:
1. phytoplankton and other organisms harness sunlight , to create photosynthesis , near hydrothermal vent there is no sunlight
2. Phytoplankton need nutrients to grow, so when there's none at the surface they can't thrive, and there's no surface in hydrothermal vent
3. The ocean's increasing acidity will most likely kill them.
Hope that helps
Explanation:
Algae called phytoplankton need sunshine to perform photosynthesis.Additionally, they need particular minerals like nitrates, phosphates, and silicates, which come from the upwelling of nutrient-rich deep waters.The varying of the seasons has an impact on both of these variables.
Why are phytoplankton cells found close to the ocean's surface?
Similar to plants on land, phytoplankton use photosynthesis to absorb energy from the sun's rays, turn it into fuel, and make oxygen from carbon dioxide.Phytoplankton are found close to the water's surface since they require the sun's energy. Similar to terrestrial plants, phytoplankton uses photosynthesis to convert solar energy into chemical energy by using chlorophyll to absorb light.They exhale oxygen while consuming carbon dioxide. Photosynthesis, the process of generating energy from chlorophyll and sunlight, is how phytoplankton obtains its energy.Phytoplankton absorb carbon dioxide and expel oxygen, just like other plants. The winter phytoplankton blooms are caused by the northeast monsoon's upwelling of subsurface water rich in nutrients to the surface layer. The phytoplankton is then moved northward by the surface flow, which displaces the center of the bloom from the upwelling centerFor photosynthesis, phytoplankton needs sunshine in addition to nutrients and a suitable environment.Only the topmost ocean layers, known as the epipelagic or euphotic zone, allow light to pass through.Few phytoplankton below this zone receive the requisite sunlight for photosynthesis.To learn more about phytoplankton refer

Answer:
Replication

Replication is the process of making copies of dna
It's obviously not respiration or diffusion, they are both completely different processes that have nothing to do with cell division
Mutation is also the wrong answer because it's a process that results a new/different type of dna

The ability to develop and use tools was first seen in early hominids. Which of the following characteristics was the main factor that contributed to this ability?
small jaw
bipedalism
compact skull
language skills
Answer:
A is incorrect, the correct answer is B bipedalism
Explanation:
The ability to develop and use tools was first seen in early hominids. The main factor that contributed to this ability is bipedalism. Therefore, option B is correct.
What is bipedalism ?When an organism uses its two back limbs or legs to travel on land, this is known as bipedalism. The term "biped" refers to an organism or device that typically travels on two feet. Bipedal motion includes hopping, running, and walking.
Hominids were able to produce and utilize tools more effectively, reach for fruit in trees, and use their hands for social interaction and display when they became bipedal.
The only bipedal animals are humans, birds, and (rarely) apes. Bipedal runners include people, some birds, many lizards, and (at their fastest speeds) cockroaches. Many birds, including jerboas and crows, as well as some rodents and kangaroos, hop while walking on two legs.
Thus, option B is correct.
