What is a biome?A biome is an ecological unit that depicts the occurrence of a biological community in response to the particular climate and the environment.
Biomes support variety of habitats across the different continents. Various biomes together constitute a biosphere.
A biome is identified on the basis of temperature and precipitation it receives annually. The presence or existence of organisms is dependent on these two factors.
Based on topography, biomes can be classified into terrestrial, fresh water and marine biomes.
Some of the well known examples of biomes include tundra region, taiga region, grasslands, desserts and forests.
There are also special types of biomes known as ecotones where the two biomes merge. Salt marshes are the example of ecotone.
Thus, biome is the life supporting unit in ecology.

Students observe several slides of tissue cross-sections under the microscope. They are asked to develop a key system to classify the slides as coming from either monocot or dicots. What key system should the students develop
As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the vascular bundles.
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain randomly scattered bundles located throughout the stem. On the other hand, dicots have their vascular bundles more neatly organized in concentric circles. These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.

Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

What is the empirical formula of a compound that contains 4.03 g of hydrogen per mole, 64.14 g of sulfur per mole, and 128.00 g of oxygen per mole?
Answer:
Oct 27, 2015 · CH_4 For this kind of problem, you can assume that the weight of the unknown sample is 100g ( since 75% C + 25% H = 100%). Thus, weight of C = 75g weight of H = 25g Since chemical formulas deal with number of moles rather than weight in grams, you need to convert each element by multiplying it to their respective atomic masses.
Explanation:
The empirical formular i H₂SO₄
The first step is to calculate the compound by the molar mass
Hydrogen, Sulphur, Oxygen
4.03/1 , 64.14/32 , 128/16
4.03 , 2 , 8
Divide by the lowest value
4.03/2 , 2/2 , 8/2

The Process of Cellular Respiration
Cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat. How does cellular respiration happen inside of the cell? Cellular respiration is a three step process. Briefly:
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis.
In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells (Figure below). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle. Notice that mitochondria have an inner membrane with many folds, called cristae. These cristae greatly increase the membrane surface area where many of the cellular respiration reactions take place.
In stage three, the energy in the energy carriers enters an electron transport chain. During this step, this energy is used to produce ATP.
Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose. The later steps release much more ATP.
The process is of cellular respiration. Cellular respiration is the process through which the glucose in the food you eat is converted into ATP, which is then converted into energy.
What is cellular respiration?
In the first stage, a procedure known as glycolysis breaks down glucose in the cell's cytoplasm.
The pyruvate molecules are delivered to the mitochondria in stage two. The organelles known as the cellular "powerhouses" of energy are called mitochondria
Pyruvate enters the Krebs cycle in the mitochondria after being transformed into a 2-carbon molecule. These cristae significantly expand the area of the membrane where most cellular respiration occurs.
Therefore, The process is of cellular respiration. Cellular respiration is the process through which the glucose in the food you eat is converted into ATP, which is then converted into energy.

.
Answer : 0.0001
Explanation:
Since males only have 1 X chromosome, the number of males with h alleles should be equal to number of males with Haemophilia and therefore the frequency of males with Haemophilia must be equal to the frequency of h alleles on X chromosome.
