En un cultivo de células vegetales se introdujo una mutación genética que produjo como consecuencia la incapacidad de estas células para polimerizar todo tipo de moléculas de glucosa. ¿Que consecuencias podrían haber para estas células?
Explanation:
Aun cuando los procesos de replicación del material genético son muy precisos, no son perfectos, por lo que pueden producirse errores que generan cambios. Una mutación es una variación espontánea o inducida del genoma, un cambio permanente y heredable en la secuencia del ADN, en nucleótidos, o bien en la disposición del ADN en el genoma.
Estos cambios o mutaciones se deben a alteraciones de la información genética. Las consecuencias dependen entonces del nivel de afectación: desde cambios en la secuencia nucleotídica, en los genes o los productos génicos, hasta en los tipos celulares involucrados.
Todos los seres vivos cuentan con sistemas de verificación y reparación de los procesos celulares. En el caso de la replicación del ADN existen sistemas de reparación específicos y bien coordinados, pero en ocasiones las lesiones del ADN que escapan a esta verificación serán las causantes de ocasionar mutaciones; por lo tanto, la efectividad de la lesión dependerá tanto de la tasa de división celular, como de la eficiencia de los mecanismos de reparación contra el aumento en las lesiones al ADN. Cuando ambos factores están incrementados, el resultado será una mayor generación de mutaciones o mutagénesis (y carcinogénesis).
Plants have low energy needs as compared to animals. Explain.
➜ Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search or food. So, they require more energy.
➥ Plants have low energy needs as compared to animals because they do not move. Moreover, in a large plant there are many dead cells like sclerenchyma because of which they also need less energy.

5 How does the presence of coal on Antarctica indicate a climate change?
The discovery of a new coal deposit means people will be able to use this found fuel longer.
Coal forms from the remains of plants that lived in tropical swamps millions of years ago, Coal deposits can tell scientists what the composition of the atmosphere was in the past.
Coal is burned for fuel and it releases carbon dioxide into the atmosphere.
Answer:
The discovery of a new coal deposit means people will be able to use this fossil fuel longer.
Coal is burned for a fuel and releases carbon dioxide into the atmosphere.

Iron is with one kind of atom that combines with oxygen from the air to form rust (iron oxide). Rust contains two types of atoms, which means it is .
Answer:
A compound
Explanation:
A compound is a substance (pure) that contains two or more different types of atoms chemically combined together. In other words, a compound is formed from the chemical combination of two or more elements.
According to this question, iron (Fe) is an element with one type of atom that combined with oxygen in the atmosphere to form iron oxide known as RUST. This is primarily what happens when a ironic substance is said to RUST. Rust is a combination (chemical) of two different kind of atoms i.e. iron and oxygen, hence, it is a COMPOUND.

Theories are put into action once large amounts of research and evidence can be provided to prove a theory. Scientists especially need lots of evidence in order to prove a point and their theory.
In watermelons, the gene for green fruit (G) is dominant to the gene for striped fruit, and the gene for round shape (R) is dominant to the gene for oval shape. Suppose a plant with genotype GGrr, is crossed with a plant with genotype ggRr. What would be the expected phenotypes among the offspring?
F. 100% green and oval.
G. 50% striped and round; 50% striped and oval.
H. 100 % green and round.
J. 50% green and oval; 50% green and round.

Explanation:
Distinguish between breathing and respiration.
As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
➜ Breathing:
The process of obtaining oxygen and releasing carbon dioxide is called breathing.It is a physical process.It takes place in the lungs.It utilises energy from the food.Respiration:
The process of releasing energy from food is called respiration.Heterotrophs are directly or indirectly dependent on autotrophs.It takes place in the lungs as well as in mitochondria.It releases energy from the oxidation of simple food.The dangers of electrical shock can vary depending on the situation. Which of
the following would be the most dangerous (most likely to get a nasty shock!) ...

Explanation:
The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?
Answer:
because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements
Explanation:
The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.
Noble gases refer to elements in group 18. These elements are renowned for being inert.
As a result of their inertness and because they are all gases, they are sometimes called "inert gases".
This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

What is Female reproductive organ?One ovary is located on either side of the uterus in the majority of females. They have two primary functions: generating hormones and releasing eggs. They are roughly the size and shape of an almond.
At birth, two ovaries each hold about 700,000 immature eggs, or oocytes (Trusted Source). These eggs start to grow and mature inside the ovary follicles after a person reaches puberty.
A developed egg is released by the ovaries around once every month. The menstrual cycle includes a process called ovulation, which is what gives rise to eggs.

b)recessive
c)It cannot be determined
d)It varies depending on whether an individual has one or two copies of the allele
In cats, the allele (B) produces black color but (b) produces a yellow color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell color. The alleles (B) and (b) are sex-linked as well. Cross a tortoise shell female with a yellow male.
A.vWhat percent of their offspring will be yellow?

C. What percent of their offspring will be tortoise shell?
D. Why is it impossible to have a tortoise shell male offspring?
Answer:
a. 50%
b.25%
c. 25%
d. Why is it impossible to have a tortoise shell male offspring? the x chromosome, a male can only have one copy of the allele - either B. orb, not both!
Explanation:
Alleles can be referred to as alternate forms of a gene. Incomplete dominance refers to two true-breeding parents crossed to give an intermediate phenotype.
The allele (B) produces black color but (b) produces a yellow color. A heterozygote produces a tortoise shell color (Bb)
Cross a tortoise shell female with a yellow male.
Bb x bb
Bb Bb bb bb
c. Bb --- 50% tortoise shell color
a. bb --- 50% yellow color.
b. No black -- 0%.
d. The males offspring cannot be tortoise shell because they have just the one X chromosome on which this gene resides. So they are either black or yellow.
