Answer:
They did not try to do this.
Bird flu, when it first crossed over to humans, was not human to human transmissible.
But as a virus evolves, we expect sooner or later that it would get that ability.
Researchers do not need to try to get evolution what evolution would do all by itself anyway.
I know that very often the people that say that the Chinese created a virus in a lab are also people that say that they do not believe in evolution.
Stop being a hypocrite about it.
No one was researching how to do this, no one needed to research how to do this because this is done naturally by natural evolution, and no one would want to do this for any reason.
When you accuse “researchers” of trying to do something that has no benefit to science then you accuse all science researchers when you lie about it.

What kind of virus caused the 1918 pandemic?
Answer:
The answer is Spanish flu
Answer:
H1N1 virus with genes of avian origin
Explanation:
The outbreak was caused by an influenza type, where the subtype of it is know as H1N1 virus.(. Characterization of five of the eight RNA segments of the 1918 influenza virus indicates that it was the common ancestor of both subsequent human and swine H1N1 lineages, and experiments testing models of virulence using reverse genetics approaches with 1918 influenza genes have begun in hopes of identifying genetic features that confer virulence in humans.....

Un tanque cilindrico de gasolina tiene 3 m de altura y 1.2 m de diámetro. ¿Cuántos kilogramos de gasolina es capaz de almacenar el tanque?
Plan: Para calcular la masa, primero debemos determinar el volumen del cilindro circular
derecho (V = irr2h), donde r = jD = 0.60 m. Por tanto, la masa se determina a partir de
la ecuación (15.1).
Solución: El volumen es
V = 7rr2h = 7t(0.6 m)2(3 m); V = 3.39 m3
Al resolver la ecuación de la densidad para m tenemos
m = pV = (680 kg/m3)(3.39 m3); m = 2310 kg
Otro método para indicar las densidades de las sustancias es la comparación su densidad
con la densidad del agua. La relación de la densidad de la sustancia con respecto a la del agua
se vuelve entonces la gravedad específica, la cual es una cantidad sin dimensiones. Si un
objeto tiene el doble de densidad que el agua, su gravedad específica es 2; un objeto que tiene
una tercera parte de densidad que el agua tiene una densidad relativa de 1/3.
La gravedad específica de una sustancia se define como la razón de su densidad con respecto a la densidad del agua a 4°C (1 000 k g /m 3).
Un mejor nombre para esta cantidad es densidad relativa, pero el término gravedad específica
se usa más ampliamente.

If fertilization occurs which layer does the egg burrow into
a.myometrium
b.perimetrium
c.endometium
According to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.
What is endometium?It is the tissue that covers or upholsters the uterine cavity whose function is to receive the fertilized egg when pregnancy occurs, that is, it allows the implantation of a fertilized egg, which will later transform into a new being.
For the endometrium to carry out its function, it has to undergo a series of morphological and functional modifications linked to the secretion of hormones by the ovaries so that at the time of greatest receptivity, the endometrium has the thickness and the nutrients necessary for a correct interaction with the embryo.
Therefore, we can conclude that according to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.

Speculate on how an increase of carbon dioxide and a decrease of oxygen might affect the pond ecosystem.
Answer:
There will be a reduction in the number of species in the pond
Explanation:
Oxygen is a very pivotal substance needed for the growth and metabolism of living organisms as it is a requirement for the process of cellular respiration that generates energy in cells.
If oxygen begins to reduce, there will also be a reduction in the number of organisms in the pond ecosystem because every cell undergoes cellular respiration.
Use a Punnett Square of a Bb x Bb cross. B is the factor for brown eyes and bis factor for blue eyes. What color eyes do the parents have:
Answer:
The parents would have brown eyes.
Explanation:
Given Bb x Bb, this tells you that both parents have brown eyes and are carriers for a reccessive trait (blue eyes). Remember that the uppercase letters are considered dominant and the lower case letters are considered recessive. In order for the blue eye allele to show, you would need to have the genotype: bb.
C. Brown
The parents would have brown eyes.
Given Bb x Bb,
This tells you that both parents have brown eyes and are carriers for a recessive trait (blue eyes).

Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.

Through the process of cellular respiration, organisms mix oxygen with food molecules.
What is cellular Respiration?Directing the chemical energy contained in these substances toward life-sustaining processes, while excreting carbon dioxide and water as waste.
Utilizing sunlight, carbon dioxide, and water, plants use the process of photosynthesis to produce glucose and oxygen.
The conversion of glucose into cellular energy takes place during cellular respiration. They are polar opposites that feed off one another in a never-ending loop.
Therefore, both Photosynthesis and cellular Respiration are considered opposite reactions and oxygen is the products of one reaction are the reactants of the other reaction.

Explanation:
Yes , after conducting research, conclusion need revision. After the research is conducted the results are discussed with the peers to get their affirmation on the same and in case if they feel that there are some issues with the result obtained in practical sense, they ask the researcher to confirm his/her experiment once again and in lieu to revision there are chances that the results need to be revised once again.

and genotypes in blood group
genes.
In the blood group systems, the phenotypes largely depend on the genotype.
A phenotype is an observable trait of an organism, which depends on the genotype, environment, or both.For example, the blood group system ABO is dependent on the presence of certain antigens on the surface of blood cells.In this system, A and B are codominant alleles, whereas O is recessive and therefore it is not expressed in heterozygous individuals.In conclusion, in the blood group systems, the phenotypes largely depend on the genotype.

In the blood group system, the concept of Co-dominance is applied, where the phenotypes depend on the genotypes.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or the manifestation of characters. Phenotypes are also known as traits.
Co-dominance is a condition where both alleles in heterozygous conditions give visible expression. ABO blood group system in humans depends on certain antigens on the surface of blood cells. Alleles A and B are co-dominant while allele O is recessive.
Therefore, in the blood group system, the concept of Co-dominance is applied, where the phenotypes depend on the genotypes.
