When we place a teabag in hot water, the water takes on a brownish colour. Explain which process has taken place.
Answer:
diffusion
Explanation:
the particles form the tea are moving from an area of high concentration of tea to a low concentration of tea. If you want to be even more speficic this is osmosis; the diuffuion of partcles in water

Which of the following represents a possible chromosome number of a species that uses sexual reproduction, and why?
A
62, because this number will create a diploid cell, the result of both female and male gametes combined.
B
62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
С
23, because this number will create a diploid cell, the result of both female and male gametes combined.
o
D
23, because this number will create a haploid cell, allowing both female and male gametes to be combined
Answer:
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Explanation:
Sexual reproduction involves two organisms to come together (male and female). Sexually-reproducing organisms make use of a process called MEIOSIS to produce gametes or sex cells, which have a reduced number of chromosomes as the parent cells producing them.
A sexually reproducing organism must contain a complete diploid chromosome number (2n) that allows it to produce cells with a haploid chromosome number via meiosis. The haploid gamete cells that result from each meiotic divisions of male and female parents can combine to form a whole diploid organism.
The number of a species should be uses se-xual reproduction,
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Se-xual reproduction:It includes the two organisms for come together i.e. male and female. It make use of a process known as MEIOSIS to generate gametes. A se-xually reproducing organism should contain a complete diploid chromosome number (2n) that permits it to generate cells with a haploid chromosome number via meiosis.

In your letter, you need to explain how the theory of evolution is supported by evidence. Be sure to include the 4 pieces of evidence for evolution as well as an example of each.
The evidence of evolution was posited by Charles Darwin. The theory of evolution states that all species are related and that they change over time
The different postulates of Drawin support the natural selection phenomenon. Darwin stated that the organisms that are fit and are able to change according to evolution are able to survive. This was known as the survival of the fittest.
The evidence of the evolution can be studied by fossil record , comparative embryology , molecular biology , and comparative anatomy.

Compared to the Sun, the star Betelgeuse is
A. Less luminous and warmer
B. Less luminous and cooler
C. More luminous and warmer
D. More luminous and cooler
Red supergiant star Betelgeuse is around 764 times as massive as the Sun. To put that into perspective, the diameter of Mars' orbit around the Sun is 328 times that of the Sun. Thus, option A is correct.
What is the comparison of Sun and star Betelgeuse?Betelgeuse is 640 light years away from the sun. Given that the star is only 10 million years old, it will die young like earlier supergiants.
The sun, in contrast, is only approximately halfway through its life and is nearly 4.6 billion years old.
Betelgeuse is one of the gleaming stars in the night sky and can be seen clearly on the right shoulder of the constellation Orion.
Betelgeuse is a red supergiant that is 1,400 times bigger than our Sun and thousands of times brighter.
Therefore, Compared to the Sun, the star Betelgeuse is Less luminous and warmer.

A company wants to build a new store. After reviewing the piece of land it is determined that a threatened woodpecker nests in that area .If the company is granted permission to build , what is the most environmentally responsible action by the company
Answer:
Explanation:
If the piece of land is forested or covered with many trees, the company can decide not to bring down all the trees (leaving some trees standing) and move as many as possible nests to the available trees within it's land. This will prevent emigration of the woodpeckers and can ultimately help conserve the woodpeckers in that land and indeed the area in which the land is situated.
This is most environmentally friendly because killing or scaring away of the birds by destroying there homes could lead to imbalance in the environment and even cause gradual extinction of the birds in the environment/area.
According to natural selection theory, Different species occupying the same habitat will adapt to that habitat by undergoing the same genetic changes Adaptations beneficial at one time should generally be beneficial during all other times Well-adapted individuals have more offspring, and thus contribute more to the next generation's gene pool, than do poorly adapted individuals. Adaptations beneficial in one habitat should generally be beneficial in all other habitats
Answer:
The most correct statement is - Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.
Explanation:
Adaption in natural selection is a species, time-specific, and habitat-specific process. So, it means if a species is adapted to genetic changes in a particular habitat, it is not necessary that all other species also adapt to similar genetic changes.
Similarly, if a species has beneficial adaption for a particular habitat, it is not necessary it will be beneficial for the other habitat as well.
Thus, natural selection leads to the well-adapted individual that leave more offspring and contribute more to the gene pool.

They have been hand-pollinated and are patented, often sterile, and genetically identical within food types. These plants are usually grown in a monocultural environment and are cultivated for mass production and sale. They must be sturdy to withstand mechanical picking and cross-country shipping. They do not compare to the quality and taste of heirloom plants, but they do produce large, healthy fruit that appeals to most shoppers. Unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again.

Answer:
vascular plants have a top and bottom ,a trunk and branches ,leaves or needles the bottom is a system of roots. Xylem and phloem make up transportation system of vascular plants. Xylem is made of vessels that are connected end to end to move water around.
Open and closed circulatory systems are found in animals. blood vessels transport all guilds into a cavity. when the animal moves the blood inside the cavity moves around the body in all directions. most invertebrates like crabs, insects, snails etc...have an open circulatory system.

Explanation:
A shipwrecked sailor is stranded on a small desert with not fresh water to drink. He knows he could last without food up to a month, but if he didnt have water to drink he would be dead within a week. Hoping to postpone the inevitable, his thirst drove him to drink the salty seawater. He was dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all?
Answer: The salt dried and dehydrated him even further.
Explanation: When we become dehydrated, the sodium concentration in the body is already elevated. Adding salt only aggravates the condition by forcing the kidneys to excrete more water in order to eliminate the extra salt.
