Basic Biology Question Help

Please help with 3 basic biology questions plz!?

I even have been blocked additionally. an identical guy or woman who blocked @secretsauce additionally blocked me. She would not like it while her idiotic statements approximately evolution are refuted. I even have additionally been stated and my answer deleted a number of instances using fact those reporting me do no longer like it when I disclose the lies they use approximately evolution. And it form of feels that that's impossible to get Y!A to opposite the deletion. for example, in a pair of situations the reporter had used hyperlinks to internet web content that used despicable arguments against evolution and that i uncovered them for being despicable. i attempted to get my answer reinstated yet curiously the hypocrisy of the deletion did no longer propose something. via ways, evidently that my punishment for being stated is to have my avatar label as a real Contributor additionally deleted. added: @im: "you're able to be blocked from conversing with an solutions member, yet you won't be in a position to be blocked from answering the question of any solutions member. " incorrect! If the member blocks you, the question would not arise once you click on it. fairly there's a message saying you may't get right of entry to the question immediately. added: @Mithroramir: "the massive bang concept is the scientific advent tale, even with the undeniable fact that it claims that mild can't age (relativity concept) and yet it does age via distinctive characteristic of the backround microwave radiation stumbled on via Penzias and Wilson. So which of those 2 together unique propositions is real? " you don't comprehend what the cosmic microwave history is. the enlargement of area from the time of the massive bang has stretched the unique radiation to a plenty decrease frequency. massive Bang concept held that the unique radiation would have stretched via a undeniable quantity and that quantity grew to become into what grew to become into measured. That length provided confirmation of the massive Bang. you will desire to get your the help of good sources (or is what you stated merely something which you erroneously got here up with on your guy or woman concepts).

Basic biology science questions help.?

In biology, a skeleton is a rigid framework that provides protection and structure in many types of animal, particularly those of the phylum Chordata and of the superphylum Ecdysozoa. Exoskeletons are external, as is typical of many invertebrates; they enclose the soft tissues and organs of the body. Exoskeletons may undergo periodic moulting as the animal grows. Endoskeletons are internal, as is typical of many vertebrates; they are usually surrounded by skin and musculature, though they often enclose vital organs. Endoskeletons are attachment points for musculature and act as leverage for movement, and in many animals contain marrow, which produces blood cells. Skeletons may or may not be mineralized - human skeletons are calcified, while shark skeletons are cartilaginous - and may be jointed for flexibility and motility or rigid for structural strength. The average adult human skeleton has around 206 bones. [1] These bones meet at joints, the majority of which are freely movable. The skeleton also contains cartilage for elasticity. Ligaments are strong strips of fibrous connective tissue that hold bones together at joints, thereby stabilizing the skeleton during movement.

Hi!
1. A cell is the basic unit of life. It is the smallest unit (or building block) of a living organism that is capable of life and it carries out various processes. Its composition enables to carry out various activities like transporting materials throughout the cell, making food, releasing energy for cell to use.
2. Nucleus protects DNA and organizes replication, transcription and RNA processing. The nuclear membrane allows m-RNA and ribosomes to go through it when needed. Ribosomes are mainly responsible in protein synthesis, consists of rRNA and protein molecules, which make up two subunits; 30S subunit binds mRNA in initiation and holds growing peptide (protein) chain while the 50S subunit accepts charged tRNAs.
Hope this helps! ^_^

Biology question help! thanks?

E, polarity.

Polarity pulls the negative charge partially toward the oxygen, which gives the molecule dipoles. With a slightly positive and slightly negative end, the molecules attract--but don't bond to--other atoms with dipoles, such as other water molecules. This hydrogen bonding (again, as a RESULT OF the polarity) is what causes the "stickiness" of water molecules, and creates adhesion and cohesion.

As a polar substance, water can dissolve other polar substances with ease. This is why water dissolves many things, especially biologically--ions tend to have dipoles.

Also, the strength of the covalent bonds in water, and its weaker but relatively strong hydrogen "bonds" between other molecules, makes it harder for water to evaporate than other molecules, and gives it a high specific heat.

Help with Basic Biology Multiple Choice Questions?!?

Answers:
1: B - Sugars. Photosynthetic organisms trap the energy from the sun and turn it into sugar (food!).

2: B - Provided by carbon dioxide. Photosynthetic organisms use the carbon from carbon dioxide to form sugars, then give off the remaining oxygen. This is why plants, like trees, are so important to the planet - without them, we wouldn't have oxygen to breathe!

3: B - energy is released. ATP is the most important energy molecule in the cell and is necessary for almost every activity that the cell can perform. Once the organism makes sugars during photosynthesis, it breaks down those sugars to make ATP. Humans also break down sugars to make ATP, but we get our sugar by eating food, not by using the sun's energy.

Basic Biology Questions (Evolution)?

Hey guys I need help on some of these thank you!!!

Which of the following lists events in the proper order to reflect how natural selection works in a population of lice that could originally be controlled by permethrin?

A). Permethrin resistance is common in lice; permethrin is used to kill lice; most lice become sensitive to permethrin.

B). Permethrin is used to kill lice; individual lice change in order to survive exposure to permethrin; most lice become resistant to permethrin.

C).Some lice are resistant to permethrin; permethrin is used to kill lice; lice resistant to permethrin become the most common type.

D). A louse population evolves resistance to permethrin; permethrin is used to kill lice; lice become more common in schoolchildren.


Which of the following is an example of microevolution?
HIV evolved resistance to antiviral medications.
Birds evolved from dinosaurs.
Lions and cheetahs evolved from a common cat-like ancestor.
Land plants evolved from algae.


The most important reason that one can see evolution in a population of mosquitoes more easily than one can see evolution in a population of squirrels is because mosquitoes *
have a higher mutation rate.
have a shorter generation time.
lay eggs rather than bear live young.
feed on blood.

1. In plant cells, since they have a cell wall, you just see a cell wall formation and then they separate.

3. Cancer cells no longer undergo mitosis because they lack the check points. They are permanently in interphase, which is the reproductive phase and that's why they are a problem. They are damaged cells that never get checked and fixed and reproduce like crazy!
