Answers
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.
The dandelion is a successful weed. Explain why its adaptations make it a better competitor than many other plants on a school field or a garden lawn.
Answers
Answer:
The correct answer is - dandelion weeds adapted many tricks to reduce all other competitors as it is invasive species.
Explanation:
The dandelion is a successful weed. It's got a lot of adaption to eliminate or dominate other plants and weeds, such as ethylene gas released by its rosette of leaves that prevent other plants from growing near dandelion.
Seeds of dandelion also adapted seed dispersion tactic by seed-parachutes into the wind. Dandelion weed does not require to be pollinated and rapidly increases their numbers. Dandelion has a taproot that goes deep into the soil, up to three feet down for water and nutrients.

For a certain plant, purple flowers (allele: P) are dominant and white flowers (allele: p) are recessive. A heterozygous purple plant is crossed with a true-breeding (purebred) white plant. What are the possible genotypes (allele pairs) of the offspring?
Answers
The possible genotype of all the offspring will be PP, and Pp as per the given situation.
What is genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.
The term "genotype" broadly refers to an organism's genetic make-up; in other words, it characterizes an organism's whole gene pool.
The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
In the Punnett square attached, the genotype of the organism is PP and Pp, which means the generation will be having purple flower.
Thus, the possible genotype will be 50% PP and 50% Pp.

Random mutations may occur because a change in the order of nitrogen bases in a codon. One type of mutation involves a substitution of one of the nitrogen bases in a codon. What amino acid is called for by GGA codon?
Answers
Answer:
Alanine
Explanation:
Using the codon chart (see the attached image), that is, a chart of triplet codes and the corresponding amino acids that they represent, the amino acid called for by GCA codon is alanine.
There are 64 possible codons in nature from 4 nitrogen bases - adenine (A), guanine (G), cytosine (C), and uracil (U). The codes are degenerates because they represent only 20 naturally occurring amino acids. Hence, more than one codons codes for each amino acid. Apart from GCA, other codons that translate as alanine include GCU, GCC, and GCG.

D) Evaporation and precipitation
Answers
Answer:
D
Explanation:
I took the test for flvs, it was correct.
The process that directly connect the ocean to the water cycle is evaporation and precipitation. The correct option is D.
What is water cycle?The water cycle is a biogeochemical cycle that describes the continuous movement of water on, above, and below the Earth's surface. It is also known as the hydrologic cycle or the hydrological cycle.
The water cycle depicts the continuous movement of water within the Earth's and atmosphere's atmosphere.
It is a complicated system with numerous processes. Liquid water evaporates into water vapour, condenses into clouds, and falls back to earth as rain and snow.
The water cycle describes the exchange (cycling) of water through Earth's land, ocean, and atmosphere. Evaporation and precipitation are the processes that directly connect the ocean to the water cycle.
Thus, the correct option is D.

The instructions, or 'code', in our DNA is dependent upon the order of the _____ in the DNA
-phosphates
-proteins
-bases
- sugars
Answers
Answer:
C. Bases
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the a type of nucleic acid that serves as the genetic material in living organisms. DNA holds information or instructions needed for the synthesis of useful products like proteins that is responsible for growth, reproduction, and general survival of organisms. Hence, it is referred to as the "BLUEPRINT OF LIFE".
However, in the structure the of the DNA molecule, it contains certain monomeric building blocks called NUCLEOTIDES. These nucleotide bases are of four types namely: Adenine, Thymine, Guanine and Cytosine. It is upon these order of nucleotide bases that instructions, or 'code', in our DNA is dependent upon.

The hours of daylight can vary greatly because of latitude. How would being near the equator shape the amount of sunlight per day in those countries? Explain your answer.
Answers
Answer:
Explanation:
The amount of daylight that is received is directly proportional to how close the sun is to each hemisphere. This happens due to Earth's inclined axis which changes as the Earth rotates and causes more daylight in the Northern or Southern hemispheres which is when summer starts in each. That being said the Equator is the only location that has an even amount of sunshine all year round. This is why it is always hot and Equator cultures only recognize dry and wet seasons but still consider it summer all year round.
