Answer:
Because they are hydrophobic
Explanation:
The image shows a cell membrane, which is made up a phospholipid bilayer. The phospholipid bilayer is made up of a phosphate head, which is hydrophillic, and fatty acid tail, which is hydrophobic. That means they are repelled by water.
Because the tails are hydrophobic, they are repelled by the water towards one another, while the heads remain facing outwards,

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.

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.

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?
Answers
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.

Explanation:
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
Answers
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.

Answers
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.

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
Answers
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.
