Texto donde se desarrolle la definicion de seleccion natural. Además, empleem los siguientes terminos: Variabilidad, mecanismo selectivo y Darwin.
Answer:
la selección natural es el mecanismo principal por el cual la evolución ocurre
Explanation:
Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.
Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
a. They would have half chromosomes as much as the plants body cells.
b. Meiosis
Explanation:
Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.
Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.
In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.

what is chemical weathering? what are some facts?
Answer:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Explanation:
1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.

In 1989, a tanker carrying oil struck a reef and spilled 11 million gallons of oil in an
Alaskan bay. The oil not only spilled into the harbor, but also washed up on the
shoreline. The spill killed millions of fish, birds that lived on the shore, sea otters,
porpoises, seal lions and many whales. Every form of life in the area was affected.
Scientists have carefully studied the area and its species since the initial spill to
determine both short-term and long-term effects.
Which of the following was affected the least by this catastrophic event? A: Plants along the shoreline B: Fishermen in the area C: Migratory sea birds D: Crustaceans that lived on the bottom of the bay
Answer:
The answer is C: Migratory sea birds.
Explanation:
Sea birds that are migrating would not only just fly above the spill and nestle on the trees, but they could eat crabs and other animals that scurry around on the shore as a food source due to the death of their primary source of food, fish.
explain why aerobic respiration occurs before lactic acid fermentation in most muscles.
Aerobic respiration occurs when there is insufficient oxygen is present in respiration. If the body does not respire enough, the cells respire anaerobically. During vigorous exercise, muscle cramp occurs due to the production of lactic acid by anaerobic respiration.
Aerobic respiration:Aerobic respiration occurs in the cell of the body.It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food.Water and carbon dioxide are produced as end products.Thus, we can conclude that aerobic respiration occurs when there is insufficient oxygen present for respiration. if the body does not respire enough, the cells respire anaerobically. During vigorous exercise, muscle cramp occurs due to the production of lactic acid by anaerobic respiration. The acid wears away muscles and causes cramps.

The bone cell of a goat contains 60 chromosomes.How many chromosomes will be in each daughter cell after mitosis
The bone cell of a goat contains 60 chromosomes, so there will be 60 chromosomes in each daughter cell after mitosis, as mitosis is the cell division that will produce daughter cells with the same genetic contents.
What exactly is mitotic cell division?The cell divides during mitosis, and the daughter cells formed have the same genetic content as the parents, here, two daughter cells are formed, with the bone cell having genetic content same as original bone cell. Because the duplicated chromosomes are separated equally by the spindle fibers without crossing over or recombination, 60 chromosomes will form that is the same number of chromosomes after mitosis.
Hence, the bone cell of a goat contains 60 chromosomes, so there will be 60 chromosomes in each daughter cell after mitosis, as mitosis is the cell division that will produce daughter cells with the same genetic contents.

A. True
B. False
Answer:
False
Explanation:
Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
Why is the water cycle important for ecosystems?(1 point) The water cycle helps recycle and transport carbon around the planet. The cycle replenishes the carbon supply of ecosystems. The water cycle uses photosynthesis to make clouds. These clouds make surface water that animals drink to survive in their ecosystem. The water cycle permanently removes water from underground and large bodies of water and transports it to terrestrial ecosystems that need water. The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems
Answer: The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems
Explanation:
The water cycle simply refers to how water continuously move within the Earth. It is also called the hydrological circle. Water cycle depicts many processes such as how water evaorates into vapor, how clouds are formed through condensation and then sent back to the Earth as either rain or snow.

I need URGENT help with 16 through 18 pls!!!
Answer:
16. Directional Selection
17. Disruptive Selection
18. Stabilizing Selection
19. Natural Selection
20. Adaptation
Explanation:
In population genetics, directional selection/positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes.
Disruptive Selection would show phenotypes (individuals with groups of traits) of both extremes but have very few individuals in the middle.
Stabilizing Selection. Occurs when individuals at the extremes of the range of characteristic are selected against. This means that the "average" individuals are selected for.
WILLL GIVE BRAINLIST!!! Suppose mechanical weathering breaks a rock into pieces. How would this affect the rate at which the rock weathers chemically? How do chemical and physical weathering differ? Explain your answer in at least 3 sentences.
Answer:
Explanation:
Mechanical weathering increases the rate of chemical weathering.
As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more surfaces on which chemical weathering can occur.
Chemical weathering is different from mechanical weathering(physical weathering ) because the rock changes, not just in size of pieces, but in composition.
That is, one type of mineral changes into a different mineral.
Chemical weathering works through chemical reactions that cause changes in the minerals.
Which statement best describes the relationship between ocean co2 and ph
Acidity rises and pH falls as carbon dioxide levels rise. The correct option is C.
What is ocean pH?A change in the characteristics of ocean water known as ocean acidification may be detrimental to plants and animals.
Scientists have noticed that the ocean's acidity is rising as a result of the water's absorption of atmospheric carbon dioxide.
Ocean acidification is the decrease in the ocean's pH level. The average pH of the ocean's surface fell from about 8.25 to 8.14 between 1751 and 2021.
Ocean water is more basic than drinking water because it is resistant to pH fluctuations due to the presence of various weak acids and their corresponding bases, or buffers.
The ocean is regarded as having a pH that is slightly alkaline. Acidity and pH both drop when carbon dioxide levels rise.
Thus, the correct option is C.

2. Which explanation for the increase in genetic diversity of this red panda population is supported by this data?
(1 point)
Red pandas in this population have encountered new predators due to the increase in deforested land, and this new predation pressure has selected for different adaptations.
Red pandas in this population have increased the number of cubs birthed by each mother every year, and this increase in population has resulted in more genetic diversity.
Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
Red pandas in this population have started eating a new diet due to the increase in deforested land, and the new dietary conditions have selected for different adaptations.
5. Which of the following scenarios would reduce the number of inheritable traits in a population, causing the individuals in that population to remain very similar to one another?(1 point)
A swamp that is being drained in order to build houses.
A forest that is being converted into farmland.
A lake that is drying up due to shifts in river flow.
A desert that has existed for millennia.
Answer:
2. C - Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
5. D - A desert that has existed for millennia.
Explanation:
2. Predation (A) and fertility (B) are easy scratch-off answers -- given the situation of deforestation, these factors will not influence genetic diversity. Although eating patterns can lead to new adaptations, the best answer is C because it results directly from the issue at hand: deforestation.
5. To limit the amount of population diversity, you would have to maintain the same environment as much as possible. In other words, migration and isolation lead to the creation of new species per Darwin's theory of Natural Selection. For that reason, the only plausible answer here is D.

Identify how information for specifying the traits of an organism is carried in the DNA.
Answer: DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
Explanation:
The traits or characters are present in the DNA in the form of genes. Genes are short stretches of nucleotides present in DNA and represent the encoded message that is present in the individual.
What is a gene?Genes are present in the DNA. It carries information about the traits that are expressed in an individual. Genes come from parents to offspring, so they are hereditary and pass from one generation to the next. From DNA, mRNA is formed from the gene by the process of transcription.
This mRNA is again converted to proteins or polypeptides by the process of translation. This product is the result of the message that is present in the gene. Example: melanin pigment and skin color variation. As different persons have variations in their genes, the production of this melanin protein synthesis varies, and as a result, skin color among individuals varies.
Hence, the information for specifying the traits is carried by genes present in DNA.
