The strangler fig is a vine that starts out as a seed in the tree canopy of the rain forest. It drops its roots down from the canopy to the forest floor. By sprouting in the rain-forest canopy, the strangler fig seedling is exposed to more-
The strangler fig plant shows an aggressive growth habit as an adaptation that allowed its growth. It drops to the forest floor and develops its seeds by exposure to sunlight. Thus, option A is correct.
What are adaptations?Adaptations are a crucial part of the evolutionary process that allows the organism to fit and survive in altered environmental conditions. It has been due to the process of natural selection that gets inherited.
The aggressive growth habit of the strangler fig vine is to ensure its survival in the rainforest covered in canopies. The seed of the plants uses sunlight and nutrients to grow at a faster rate and hangs their roots on the first floor. The sunlight increases its rate of germination.
Therefore, option A. sunlight is used for germinating the fig seeds.

Muchas especies animales son territoriales al menos durante una parte del año. Eso significa que defienden un territorio más o menos amplio en el que no dejan entrar a otros individuos de su especie. A veces, el territorio es individual, otras es de una pareja y, en otros casos, corresponde a un grupo. Explica qué distribución origina cada uno de estos comportamientos.
Answer:
Por dependencia de otros organismos y competencia.
Explicación:
Estos diferentes tipos de comportamiento se deben a la dependencia de los organismos entre sí. Algunos organismos tienen la capacidad de vivir solos y cumplir con sus requisitos de vida por lo que no permiten que otros organismos ingresen a su espacio, algunos viven en parejas y algunos organismos viven en grupos o colonias porque no pueden sobrevivir solos en ese ambiente por lo que nosotros Se puede decir que algunos organismos dependen de otros organismos y algunos pueden sobrevivir solos.
Hierarchy is a theme of biology that we see in several different topics Genetics
is one such area. Which sequence has the terms in the correct sequence from
LARGEST to SMALLEST in terms of molecular size?
A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
B. Chromosome, Nucleotide, Genome, Gene, Deoxyribose
C. Deoxyribose, Nucleotide, Gene, Chromosome, Genome
D. Genome, Gene, Chromosome, Nucleotide, Deoxyribose
Answer:
A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
Explanation:
According to this question, genetics as a branch of Biology is not exclusive of hierarchical basis. The following is an orderly sequence from LARGEST to SMALLEST in terms of molecular size:
Genome - Chromosome - Gene - Nucleotide - Deoxyribose
- The GENOME constitutes the whole genetic make up of an organism. This includes all the chromosomes contained in that organism.
- CHROMOSOME is the structure on which the inheritable unit called GENE is found.
- GENE is the molecular unit of inheritance which is made up of nucleotides.
- NUCLEOTIDES are monomers of nucleic acids made up of pentose sugar (dexyribose or ribose), nitrogenous base, phosphate group.
- DEOXYRIBOSE is a five carbon sugar that forms part of the structure of a nucleotide.

Element (maximum 2) (maximum 8) (maximum 18) -----------
Carbon- ________ ________ ________ _______
i think its
carbon- 2 (there are two in the n=1 level) 4 (there are four in the n=2 level)
i might be wrong, but hope this helps :)
Electrons in atoms are arranged in energy levels. The electrons in the energy levels of carbon are;
n= 1 ------ 2 electrons
n = 2 ----- 4 electrons
n =3 ----- 0 electrons
n = 4 ----- 0 electrons
Carbon has the electronic configuration; 1s2 2s2 2p2.
This means that there are only two electrons in the n-1 level and there are four electrons in the n=2 level.
This makes a total of six electrons in carbon as shown.

What steps are involved when a planarian needs to generate new cells
Answer:
Using this technique, which they termed 'chemical amputation', the team induced lesions in planaria and investigated which genes were activated over the course of the regeneration process. The pharynx lacks neoblasts, but cells near the wound quickly start dividing and regenerate the amputated organ.
The steps which are involved when a planarian needs to generate new cells include the different stages of regeneration.
What is Regeneration?Regeneration in the planarians depends on the presence of stem cells called as neoblasts. These newly formed cells are distributed throughout the body and, when part of the worm has been amputated, these parts are activated to reform the tissues which have been removed.
Planarians also use this extraordinary regenerative ability to reproduce asexually. Through the process of transverse fissions, planarians which anchor their tails and also essentially pull themselves apart from each other, resulting in two fragments which include one head and one tail that will regenerate into two genetically identical worms.

ChloroplastsCell wallsAutotrophicWhat are protists?Protists are a diverse group of eukaryotic organisms that are not animals, plants, or fungi. They are typically unicellular but can also be multicellular or colonial. Protists can be found in a variety of environments, including freshwater, marine, and soil, and can be free-living or symbiotic. They are an ancient group of organisms, and some of the earliest eukaryotes were likely protists.
The diversity of protists is immense, and they exhibit a wide range of characteristics and behaviors. Some protists are photosynthetic, using pigments like chlorophyll to capture sunlight and convert it into energy. Others are heterotrophic, consuming other organisms or organic matter. Some protists are capable of moving through their environment, using structures like flagella, cilia, or pseudopodia to propel themselves. Because of their diversity and importance in many ecosystems, protists are an important area of study in biology.

The activation of complement is effective at initiating pathogen engulfment and destruction. This immune-protective process is made possible by:
Answer:
phagocytes that have receptors for the C3b component in order to engulf and destroy pathogens
Explanation:
The complement system refers to an immune mechanism by which plasma proteins are activated by pathogens and their binding to antibodies, triggering reactions on the pathogen surface that active components with effector functions. The complement system is an essential component of the innate immune response. Phagocytic cells have receptors for the C3b component in order to bind to C3b-coated cells/particles preparatory to phagocytosis. The C3b receptor is a glycoprotein that serves to regulate the complement system by inhibiting the activation of C3 and C5 convertases which cleave C3 and C5 and thus mediate complement effector functions.
Many eukaryotic cells can be grown in tissue culture in the laboratory. Suppose you have two tissue cultures, one in G1 phase and one in S
phase. How would you determine which culture was in G, and which was in S?
I could look for growth and synthesis of proteins and other macromolecules as well as increase in organelles, which would show a culture in G1. DNA being synthesized would show in cells in the S phase.
The best way to determine if the cell is the G or S phase is by looking at the state of the DNA molecule, and the presence of histones, centrioles, and spindle fibers.
What is the interphase?
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage.During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.To determine which culture was in G stage, and which was in S stage, I would look at DNA molecule. The only stage in which DNA duplicates is during the S phase, so
If organelles are duplicated but not DNA, it is G1 stageIf organelles are duplicated as well as DNA, but the molecule is still lax, it is S phase. At this point there are also histones.If organelles are duplicated and DNA molecule began to condensate it is G2 phase. At this point there are also centrioles and spindle fibers.You can learn more about the interphase at
