Pregunta de ecología: ¿Cuáles factores ecológicos afectan a los ecosistemas acuaticos? - Describe cómo afecta cada uno de estos factores, a los ecosistemas acuáticos.
Answer:
Salinidad, acidez, oxígeno, niveles de luz y temperatura.
Explicación:
Los factores ecológicos como la salinidad, la acidez, el oxígeno, los niveles de luz, la profundidad y la temperatura son los factores que afectan en gran medida a los ecosistemas acuáticos porque estos factores proporcionan ambiente a los organismos que viven en el ecosistema. La salinidad y acidez tiene un efecto directo sobre las plantas acuáticas, si la salinidad y acidez es muy alta los organismos de ese ecosistema morirán. Los niveles de oxígeno y luz también tienen un gran impacto en los animales acuáticos, si se reducen los niveles de oxígeno y luz, los organismos morirán por asfixia y las plantas no pueden producir alimentos si los niveles de luz son bajos. La temperatura del agua ayuda a la supervivencia de los organismos porque muchos organismos son sensibles a la temperatura.
What is Mitochondria
Mitochondria was the powerhouse of the cell it contain oxidative enzymes that are needed for the stepwise oxydation of food by co2 and water. later on it converts the glucose into Atp and provide energy to body for doing activities
Hope it helps
Answer:
Mitochondria are like the power plants of the cell, similar to the engine of a car.
Mitochondria are organelles and they convert chemical energy (from food) into ATP, the main energy source for cellular work. Mitochondria suck and take in nutrients, break them down, and use it to make energy through the process of cellular respiration. One single cell has many mitochondria (1000 - 2000). This number really depends on the function of the cell.
For example, a nerve cell needs less energy than a muscle cell, and therefore will have fewer mitochondria. Kind of like a fast car needs a bigger engine than a slower car.
Also,
The mitochondria are closed in by two membranes. The outer membrane is the one that covers the organelle, and the inner membrane forms a special compartment with a fluid called the mitochondrial matrix. The inner membrane contains many folds called cristae, which increase the surface area inside the organelle. This increases the efficiency of the chemical reactions, allowing the mitochondria to create more ATP.

the answer is calculated to "Cell Wall"
Explanation:
I'm pretty sure that it's cell wall!
the members of these kingdoms all have cell walls. Which kingdoms are they?
Answer:
kingdom plantae
Explanation:
members of this kingdom have a cell wall that gives their cells a box like structure
Organisms that belong to Kingdom Monera, Protista, Fungi, and Plantae all have cell walls.
What is a cell wall?The cell wall is the outermost covering of the cell which provides the cell with a rigid structure and protects it from the outside environment. It is present outside the plasma membrane.
The composition of the cell wall differs in different organisms. The cell wall in plants is composed of cellulose, hemicellulose, and pectin. In algae, the cell wall is composed of glycoproteins and polysaccharides.
Bacteria that belong to Kingdom Monera possess a cell wall composed of peptidoglycan while the organisms of Kingdom Fungi have a cell wall made up of chitin.
Therefore, organisms of the four kingdoms Monera, Protista, Fungi, and Plantae all possess a cell wall.

Explanation:
Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. Select the steps below that describe how to construct Punnett squares.
Question:
I failed to find the options, but I will post the way by which you can construct Punnett squares.
Answer and Explanation:
First, you need to know both parental individuals´ genotypes. From these genotypes, you will get all the possible gametes for each parent, following the principle of simple segregation.
Then, by using a simple square, you will make the crosses. This is:
You will locate all the possible gametes of one parent on the top of the squareYou will place all the possible gametes of the other parent on the left edge of the square.Once you have done that, you will perform the crosses. You will look for the intersection between each parent´s gametes and place all the involved alleles in the intersection-box. These are the possible genotypes, and they will be written within the square.In the attached files, you will find an example of the cross between two pure-breeding plants.

How does human activity impact Earth's systems such as deforestation
urbanisation desertification, erosion, air and water quality, and
allemating the flow of water?**Please use full sentences ****
Answer: Land, Water,Urbanization, and smog and acid rain.
Explanation:
Smog and acid rain are produced through similar sources, primarily vehicle and industry emissions. Though both result from human-caused air pollutants, there are chemical distinctions between the two. Though there are regulations in effect to reduce both types of pollution, they remain a threat to both human health and the environment.Smog Causes A combination of three components -- nitrogen oxides, volatile organic compounds (VOCs) and sunlight -- causes smog. Nitrogen dioxide interacts with sunlight to create nitrogen oxide and a free oxygen molecule. This interaction produces ozone, which typically turns back into nitrogen dioxide, and the cycle repeats. The addition of VOCs interrupts the cycle, however. VOCs are produced by various sources, such as paint, cleaning products and refrigerants. The VOCs prevent the breakdown of ozone, allowing it to gather near the surface of the Earth, where even more nitric oxides are produced by vehicle and industry emissions, creating the dense smog seen in large cities such as Los Angeles and Beijing.Smog Hazards The presence of ozone in the form of smog can have several negative health effects. Respiratory systems can be irritated, reducing overall lung function and triggering asthma attacks. Evidence reported by the Environmental Protection Agency also suggests exposure to ozone reduces immune system responses, especially in the lungs. These effects subside over time, but little is known about the long-term effects of repeated exposure. Vegetation also suffers from smog, as plants that take up too much ozone can be damaged in ways such as discoloration and a loss of leaves that cuts photosynthesis efficiency by up to 50 percent.

During meiosis, a process known as crossing over occurs. Which statement below summarizes the results of crossing over?
O Homologous chromosomes make copies of each other.
Genetic information is removed from both chromosomes.
O DNA winds up into chromosomes and genetic information is deleted.
O DNA is exchanged between homologous chromosomes, resulting in genetic variation.
Answer:the answers is B
Explanation:
Because reproduction occurs between homologous a chromosome
During meiosis, a process known as crossing over occurs. Genetic information is removed from both chromosomes.
What is meiosis ?Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

According to the Mendel's Law of Segregation. Since, a male and a female, both with dimples, have a son without dimples which mean both the parents are heterozygous (Aa). since both are Aa × Aa there will be Aa, Aa, AA, aa. in which AA is dominant and aa is recessive thus the chance that a daughter of these parents would have dimple is 3/4.
What is Mendel's law of segregation?
Mendel's Law of Segregation states that a diploid organism passes a randomly selected allele for a trait to its offspring, such that the offspring receives one allele from each parent.
Thus, the chance that a daughter of these parents would have dimple is 3/4.

what is this data saying?
Answer:
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.
The atom shown below is
A. likely to form a covalent bond
o B. likely to form an ionic bond
C. not likely to form any bonds
OD. likely to form double bonds
Answer:
C. Not Likely to form any bonds
Explanation:
Assuming this atom is of neutral charge, it would be neon. We can tell as it has 10 electrons total. 2 in the first shell, 8 in the second. Noble gasses do not form bonds, generally speaking.
Furthermore, any atom, ion or not, that has a full valance (outermost shell) is generally not likely to form bonds.
Describe the relationship between the respiratory and circulatory systems and ATP. Use the term reactants in your response.
Answer:
Cellular respiration, which generates ATP in your cells, requires oxygen to take place, also, it generates CO2 as a waste product. The respiratory system allows oxygen to diffuse into your blood, and carbon dioxide to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.
