Answer:
Grande em tamanho, estrutura mais complexa e especialização celular.
Explicação:
As principais vantagens de um organismo multicelular em relação a uma única célula são seu grande tamanho, estrutura mais complexa e especialização celular. Os organismos multicelulares têm grande tamanho devido à presença de um maior número de células em comparação com o organismo unicelular, que é composto por apenas uma célula. Eles têm uma estrutura corporal complexa que é organizada para formar tecidos, órgãos e vários sistemas de órgãos do corpo. Eles também têm a habilidade de especialização celular, na qual células específicas têm que realizar tarefas específicas no corpo.

What is the grizzly bear?
The grizzly bear is a North American subspecies of the brown bear. Grizzlies are typically brown, though their fur can appear to be white-tipped, or grizzled, lending them their name. Grizzly bears are protected by law in the continental United States—not in Alaska—though there have been some controversial attempts to remove those protections in recent years.

Scientists have noticed that the entire DNA molecule has the same width, despite the fact that the four nucleotides are NOT the same width Now that you’ve created a model, explain why this makes sense (hint: it has to do with the number of rings for each nitrogen base)
I don't have access to your model, although I'm sure it's beautiful. Fortunately, this question can be answered without one.
A strand of DNA is a polymer consisting of monomeric nucleotide units. The nucleotides that are found in DNA are distinguished by their nucleobases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each nucleotide in DNA is made up of a single nucleobase, a sugar (deoxyribose), and a phosphate group. These nucleotides form extremely long chains comprising phosphate-sugar linkages (covalent, phosphodiester bonds).
In native, double-stranded DNA, you have of these chains (or strands) arranged side-by-side such that the nucleobases on one chain are faced directly across corresponding nucleobases on the other chain, which enables hydrogen bonding between the bases.
There is a "rule" regarding which bases form hydrogen bonds with one another (Chargaff's rule): adenine with thymine and guanine with cytosine.
What does this have to do with the width of the DNA molecule?
The four nucleotides can be structurally classified into two categories: pyrimidines and purines. For our purposes, we only need to know that pyrimidines are six-membered rings and purines are a fusion of a six- and five-membered ring (basically, purines are pyrimidines attached to a five-membered ring). Thymine and cytosine are pyrimidines, and adenine and guanine are purines.
So, geometrically, adenine and guanine are larger (and, thus, "wider") than thymine and cytosine since adenine and guanine contain an extra ring. But remember our base-pairing rules: In native DNA, adenine (two rings) on one strand pairs up with thymine (one ring) on the other strand, and guanine (two rings) pairs up with cytosine (one ring) on the other strand.
Because there's a 1:1 ratio between A:T and G:C in double-stranded DNA, the DNA molecule consists of complementary base pairs that, in any given composition of, has equivalent widths. Put simply, the A=T pair has the same width as a G≡C pair because both base pairs are between one pyrimidine and one purine.
DNA (Deoxyribonucleic acid) is composed of four nucleotides, namely, adenine, guanine, cytosine, and thymine.
Adenine and guanine are purines while Cytosine and thymine are pyrimidines.Purines are composed of two rings while pyrimidines are composed of only one ring.Purine forms bond with pyrimidine, i.e Adenine binds with thymine and guanine binds with cytosine.Adenine and thymine form two hydrogen bonds while guanine and cytosine form three hydrogen bonds.Thus, the relative pairing of the purine and pyrimidine with each other keeps the width of the DNA constant.

Humans depend on ecosystems for ecosystem services and
resources. For example, this river ecosystem provides water, fish,
and a place to swim. The forest ecosystem provides wood, shade,
and erosion control. Choose a resource and describe the possible
effects of its use on society and on ecosystems throughout its life
cycle.
Answer:
Oil.
Explanation:
Oil is a resource which has a great impact on our society because it is widely used in our daily life in the engine of vehicles. It is very necessary in the transportation sector but also adversely affected the ecosystem and the animals and plants living in that ecosystem due to production of harmful gases such as carbondioxide and carbonmonoxide gases that polluted the environment and affect the health of people.

Conclude: An organism that breaks down organic matter into simpler materials (like carbon dioxide) is called a decomposer. Decomposers absorb nutrients from living things or the organic matter they leave behind. They do not need to kill to get their food.
Do your results suggest bears are decomposers? Explain your reasoning.
Answer:
No, because bears kill to get their food. They eat fish and they kill the fish to get them. If they left the fish carcass, decomposers would eat it. The bear makes the food for the decomposers, but it is not a decomposer itself... Does that make sense?
Some bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. These drugs act as inhibitors to the bacterial enzymes but they target enzymes we don't have. Now, imagine you overhear your friend saying "antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!" Kindly explain to your friend (who has very little science background) how it is possible to target bacteria based on enzyme specificity. Be sure to include how targeting these enzymes is effective at stopping the infection.
Answer: This statement ("antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!") is wrong and can be proven to be so in the following explanation about the mode of actions of antibiotics.
Explanation:
Antibiotics are drugs which are used for the treatment of diseases caused by bacteria microorganisms. According to their mode of action, they can either be bactericidal or bacteriostatic.
Bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. Atypical example is the antibiotics, sulfonamide. This drug acts by inhibiting a critical enzyme called dihydropteroate synthase which are specific to the metabolic pathway of the bacteria cells for the synthesis of folic acid. This causes the bacteria to stop growing. Together with the actions of the immune system, the bacteriostatic actions of the antibiotics can effectively stop am infection without affecting the host cells.

How does meiosis play a role in the evolution of a species
A. It increases the reproduction rate of the species
B.it increases the amount of genetic variation in the species
C. It reduces the amount of competition between members of the species
D. It increases the ability of individuals in the species to obtain resources
Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.

Photosynthetic organisms produce oxygen based on whether light is available for photosynthesis. These organisms also consume oxygen for cellular respiration in both light and dark environments. In three to five sentences, explain how these conditions relate to gross and net
productivity. (4 points)
Answer:
Gross productivity refers to the amount of carbon fixed.
Explanation:
Gross productivity refers to the amount of carbon fixed during the process of photosynthesis by all producers such as plants and algae etc in the ecosystem. A large part of the energy that is produced in the process of photosynthesis is used by the plants in the metabolic processes of the producers such as respiration. The net productivity indicates that carbon dioxide plants that is used during the photosynthesis process substracted from carbon dioxide the plants releases during the process of respiration.

Which scientist would agree with this statement: Giraffes all had short necks originally. Individual giraffes stretched their necks for food. The "acquired" long necks from stretching were then passed on to the offspring. The giraffe population became long-necked please help I need to figure out which scientist it is
Answer:
Jean-Baptiste de Lamarck
Explanation:
His two principles were "use and disuse" and "inheritance of acquired characteristics." The latter is what the statement is referring to.
Answer:
Lamarck
In the case of a giraffe, Lamarck believed that giraffes once had short necks that got progressively longer as members of each subsequent generation stretched their necks as long as they could. In doing so, Lamarck believed that each generation would grow slightly longer necks and pass that trait onto their offspring.Jan. 16, 2018
