Answer:
Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.
Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.
Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

of the stone.
Question 2. Did the particle of the stone change in shape?
Question 3. Explain the properties of solid based on the particle nature of matter?
Answer:
No.
Explanation:
No, the stone did not take the shape of the glass because stone is not a liquid, it is a solid. Taking the shape of the container in which it is placed is the property of liquid matter whereas the solid maintain its shape and structure when placed in any container. No, the stone did not change the shape and structure when it is placed in the pail due to its solid matter. The properties of matter are the following: It is composed of tightly packed particles which make the matter solid. It maintains its shape and its particles can't move freely like gas and liquid particles.
State 8 differences between sexual and asexual reproduction
➩Reproduction:
Reproduction is a process by which living organism produce new organisms of same species (of their own kind)
Reproduction is neccessary for the survival and increase in population of species. It ensures continuity of various species on earth. In simple words if organisms will not reproduce there population will decrease and species will become extinct.
➽Mainly there are two types of Reproduction
(i) Sexual reproduction
(ii) Asexual reproduction
➩Sexual Reproduction
→ In sexual reproduction two individuals are involved to produce a new individual (male and female)
→The entire reproduction process takes longer time and more energy.
→ Population increases relatively slowly.
→ It involves more variations.
→ Species can adapt to an environment which changes.
→This leads to evolution.
→ For example:Homosapiens(Human beings)

The Group of choices associated with the question is as follows:
A) As the embryo develops, it reveals the expression of genes.
B) The growth of the embryo is achieved by the differentiation of cells.
C) A developing embryo exhibits structures not present in the adult animal.
D) The development of embryos of a certain species is consistent
Answer:
The correct answer is - C) A developing embryo exhibits structures not present in the adult animal.
Explanation:
The study of the development of anatomy to the adult form of an organism is embryology that helps in giving an idea about the evolutionary development and considered as embryological evidence which lost after developing into adult such as analogous structures.
Embryos are the structure that conserves the development pattern of widely divergent groups of organisms and therefore, used as evidence of evolutionary development.

does this an suggest evolutionary relationship? explain how these embryos can be used as evidence of a common ancestor between each of these six organism
Answer:
Examination of vertebrate embryos reveals that during corresponding stages of early development,
the embryos appear to be very similar. For example, all vertebrate embryos pass through stages in
which they have gill pouches. The pouches eventually develop into the gill apparatus in fish; in laterevolving vertebrates that do not have gills, the gill pouches undergo further refinement and develop
into structures associated with the head and neck. Similarly, all early vertebrate embryos have tails,
which persist in some animals but regress during the later stages of development of humans. Thus,
the individual development of an animal occurs through a series of stages that paint a broad picture
of the evolutionary stages (phylogeny) of the species to which it belongs.
"Ontogeny recapitulates Phylogeny", Haeckel
Explanation:
sure po ito
Examination of vertebrate embryos well-known shows that in corresponding levels of early improvement, the embryos appear very similar.
For example, all vertebrate embryos by skip thru levels in which they have got gill pouches. The pouches subsequently turn into the gill equipment in fish; in later evolving vertebrates that don't have gills, the gill pouches go through similar refinement and develop into systems related to the pinnacle and neck. Similarly, all early vertebrate embryos have tails, which persist in a few animals however regress at some point in the later levels of improvement of humans.What is ontogeny recapitulates phylogeny?These scientists claimed that ontogeny recapitulates phylogeny (ORP). This word shows that an organism's improvement will take it thru every one of the personal levels of its evolutionary history, or its phylogeny.
Thus, the man or woman improvement of an animal happens thru a chain of levels that paint an extensive picture of the evolutionary levels (phylogeny) of the species to which it belongs.

Name 3 stages of cell division, and give a brief description of what happens in each stage? please help I really need some help with this much appreciated
Answer:
Prophase
- Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process
Metaphase
- Next, chromosomes assume their most compacted state during metaphase, when the centromeres of all the cell's chromosomes line up at the equator of the spindle
Anaphase
- The progression of cells from metaphase into anaphase is marked by the abrupt separation of sister chromatids. Two separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other
Answer:
the 3 stages are: Interphase, Mitosis, Cytokinesis
Explanation:
Interphase is the phase of the cell cycle in which a typical cell spends most of its life. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions.
Mitosis: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Cytokinesis: The cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
