En los seres vivos acuaticos el oxigeno es tomado del __________ y penetra a la celula por el fenomeno de ___________
Answer:
En los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.
Explanation:
La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno. Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.
La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.
El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.
Es decir, en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.
. Some people taste the chemical phenylthiocarbamide (PTC) as intensely bitter, while others cannot taste it at all. PTC is similar to chemicals in broccoli, Brussels sprouts, and cabbage, among other plants. Tasting PTC is a dominant trait; non-tasting is recessive. About 51% of people of European descent are tasters. If all of the assumptions of Hardy-Weinberg equilibrium are met, then among people of European descent... a) What is the frequency of the non-taster phenotype
Answer:
The frequency of the non-taster phenotype among people of European descent is 49% or 0.49
Explanation:
Let us assume that the allele for tasting PTC is T, while that for not tasting PTC is t.
According to the Hardy-Weinberg equation : p² + 2pq + q² = 1
Also p + q = 1
Where p² is the frequency of individuals with the TT genotype for tasting PTC,; wow is the frequency of individuals with the heterozygous allele for tasting PTC, while q² is the frequency of the individuals with tt genotype expressed as the non-taster phenotype since the allele for tasting is dominant over that of the non-taster.
From the information provided 51% of people of European descent are tasters. Also, tasting PTC is dominant over non-tasting. This implies that individuals with TT genotype and Tt genotype will be phenotypically expressed as tasters.
Therefore p² + 2pq = 51% or 0.51
q² = 1 - p² + 2pq
q² = 1 - 0.51
q² = 0.49 or 49%
The frequency of the non-taster phenotype among people of European descent is 49% or 0.49
how are karyotypes made?
Answer: A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope.
Explanation:
Karyotypes are prepared from mitotic cells that have been arrested in the metaphase or prometaphase portion of the cell cycle when chromosomes assume their most condensed conformations. A variety of tissue types can be used as a source of these cells.

What happens to water (H2O) and carbon dioxide (CO2) during photosynthesis?
Answer:
Carbon dioxide turns into glucose and water turns into oxygen
Explanation:
carbon dioxide is combined wih hydrogen atoms in the presence of ATP molecules to form glucose
water molecules split by sunlight energy to form oxygen gas and hydrogen atoms . the oxygen obtained from water is released by the leaf as a by- product
What is photosynthesis, and what is it's main goal?
Answer: Photosynthesis is the process of when a plant makes it's own food, and the main goal is to convert solar energy to chemical energy.
Explanation: Plants use photosynthesis by taking the sunlight, to synthesize foods from carbon dioxide and water. Since plants can't move and consume other organisms, they use photosynthesis. The formula is: [tex]6CO_2+6H_2O=C_6H_1_2O_6+6O_2[/tex].
Like I said, the main goal is converting solar energy to chemical energy then store the chemical energy for future use, for example it can be used for Chemical batteries, Natural gas, Heat, Food, etc.
what is formed during photosynthesis
Answer:
Glucose and oxygen is produced
Explanation:
oxygen is usually released as a by-product and the glucose made is converted to starch and stored in leaves
plus ATP molecules are formed from excess light energy and is converted to a high energy chemical compound

Describe the importance of a hypothesis in scientific inquiry.
Answer:
The fundamental concept of a theory is that there is no predetermined conclusion. A main feature of this phase of the experimental process is deriving conclusions from theories regarding the outcomes of possible studies and then conducting certain experiments to see if the predictions are supported.
Explanation:
A hypothesis is crucial in scientific inquiry as it serves as a testable and falsifiable explanation or prediction for a specific phenomenon or observation.
It provides a structured approach to investigating a research question and guides the design of experiments and data collection.
By formulating a hypothesis, researchers set a clear direction for their study and establish a basis for drawing conclusions based on evidence.
If the hypothesis is supported by data, it strengthens the understanding of the subject matter.
Alternatively, if the data refute the hypothesis, it encourages further exploration and refinement of scientific knowledge, promoting the advancement of understanding and discoveries in various fields.

1. A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). If they had two children, a son and a daughter, what would the completed Punnett square look like (i.e., would the son have the trait, would the daughter have the trait)?
A. Both children would not inherit the trait.
B.Both children would inherit the trait.
C. Each child has a 50% chance of inheriting the trait.
D. One child would inherit the trait and one child would not.
Answer:
C
Explanation:
autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait
Using the punnet square
X x
x Xx xx
x Xx xx
there is 2 X which means there is a 50% change that their child will get the trait
In the punnett square analysis, each child has a 50% chance of inheriting the trait.
The mother Xx has the trait and the father xx doesn't.
Using the punnet square
Xx xx
Xx Xx xx xx
There are just two traits which are Xx and xx which are in equal frequency
and proportion.
This therefore means that the children have a 50% chance of getting the trait.

What conditions are necessary for rocks to melt?
Answer:
In explanation.
Explanation:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.
What is the effect of temperature on different substances?Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.
Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.
