What is Down syndrome
Explanation:
i found this on internet...
Answer:
Down syndrome is a congenital condition characterized by a distinctive pattern of physical characteristics including a flattened skull, pronounced folds of skin in the inner corners of the eyes, a large tongue, and short stature, and by some degree of limitation of intellectual ability and social and practical skills. It usually arises from a defect involving chromosome 21, usually an extra copy.

1. ¿La Meiosis es la división propia de células?
Answer:
Explanation:
Al igual que la mitosis, la meiosis es una forma de división celular eucariota. Sin embargo, estos dos procesos distribuyen el material genético entre las células hijas resultantes de formas muy diferentes. La mitosis crea dos células hijas idénticas, cada una de las cuales contiene el mismo número de cromosomas que su célula madre.

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.

Hemophilia is an X-linked trait caused by the allele h. About 1 in 10,000 males (0.0001) has hemophilia. The frequency of the h allele in males is therefore
.
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.

The star in the diagram represents which of these? A. origin of replication B. replication fork C. replication bubble D. Okazaki fragment
Given what we know about the process of DNA replication, we can confirm that the star shown in the diagram represents the replication fork.
During the replication of DNA in the cellular process of multiplication, a structure known as the replication fork is formed. This fork is a structure that forms by helicases, which tear the hydrogen bonds that hold together two DNA strands in the form of a double helix.
The resulting structure contains two prongs, which are branches of the original DNA strand which are no longer doble or in the form of a helix. This area where the strands are separating into prongs is the replication fork which is being marked in the diagram by the star.

Which statement contains inaccurate information about stem cells?
Stem cells are undifferentiated.
Stem cells are specialized.
Stem cells can make more cells of the same type through cell division (potentially indefinitely).
Answer:
The incorrect statement is stem cells are specialized.

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.

The presence of a cholesterol in the plasma membrane of some animals
Answer:
The amount of cholesterol in animal plasma membranes regulates the fluidity of the membrane and changes based on the temperature of the cell's environment. In other words, cholesterol acts as antifreeze in the cell membrane and is more abundant in animals that live in cold climates.

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.

Which is the better soil amendment: compost, vermiculite, and manure? Why?
Answer:
All of them are great, but compost and manure are probably best because they still have protiens and energy stored in them.
Have an awesome day friend! :D
Explanation:
Compost: (permeability, water retention, nutrients) Well-rotted compost is one of the best soil amendments you can add to your garden, and it’s impossible to use too much! Compost is highly fertile and lightens heavy soils while providing structure to loose soils. It also possesses the amazing ability to help soil retain much needed water while improving drainage – making compost great for both clay and sandy soils. Compost lasts about six months but has a long-term impact on soil microbes and overall fertility. Continue to add compost, and watch your soil get better and better.
Greensand: (provides permeability, nutrients) This powdered rock material provides slow release nutrients, such as potassium and other trace minerals. It also helps loosen compacted soil.
Sand soil amendment
Sand soil amendment.
Gypsum: (permeability for saline soils) While powdered gypsum is considered an amendment for clay soil, it’s actually more important for saline soils where it loosens the clay by reacting chemically with the salts.
Leaf Mold: (water retention, texture, nutrients) Made from shredded, composted leaves, leaf mold holds moisture, loosens soil, provides organic matter, and breaks down slowly to improve overall soil texture. Leaf mold also encourages beneficial microbes that help transfer nutrients to plant roots.
Manures: (texture, nutrients) Composted manures are affordable, readily available soil amendments. Like other forms of compost, manure provides the right balance of drainage and water retention. Manures are high in nitrogen and other nutrients, so they’re particularly useful as slow release fertilizers. Manures can add salt to the soil, so they may not be suitable if your soil is already saline. Use only well rotted manure to prevent burning due to high nitrogen content.
