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).
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?
B. What percent of their offspring will be black?
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.

Your stomach pH is about 2. Would you expect starch
digestion to take place in the stomach?
Answer:
The correct answer would be - no or very less.
Explanation:
Digestion of the carbohydrates including starch begins within the mouth with the help of amylase into maltose. Most of the starch digestion takes place in the small intestine.
The significant digestion of starch does not take place in the stomach due to the acidity of the stomach as at low pH, amylase denatured or stay inactivated. Once the starch fragments reach the small intestines pancreatic amylase digest starch.
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.

How does the support structure of echinoderms differ from that of arthropods?
will give brainliest
Answer:
I would say the main difference is their covering. Arthropods have an exoskeleton, which protect their soft bodies while echinoderms have living endoskeletons. Overall, arthropods are more closely related to nematodes than echinoderms.

which led to the development of Penicillina??
Answer:
Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens. Fleming's student Cecil George Paine was the first to successfully use penicillin to treat eye infection (ophthalmia neonatorum) in 1930.

Explanation:
Biologists refer to the number of chromosomes with an "#n". For example, 1n for one copy of chromosomes and 2n for two copies. How else can this be expressed?
Answer:
haploid/diploid
Explanation:
The number of chromosomes can also be expressed as haploid or diploid, instead of 1n for one copy and 2n for two copies.
The haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms while the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms.
So, in other words: n = haploid and 2n - diploid.

Answer:
Because the duplicated chromatids remain joined during meiosis I, each daughter cell receives only one chromosome of each homologous pair. ... By shuffling the genetic deck in this way, the gametes resulting from meiosis II have new combinations of maternal and paternal chromosomes, increasing genetic diversity.

Most Swiss starlings produce four to five eggs in each clutch. Starlings producing fewer or more than this have reduced fitness. Which of the following terms best describes this situation? (3 points)
The bottleneck effect will result in a small gene pool with little genetic diversity.
Directional selection will happen because the population individuals will be unable to adapt, leading to extinction.
Disruptive selection will result in the population of birds' risk decline, due to reduced number of eggs.
Genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection. I think is D
Answer:
D: genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection.
Explanation:
Genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection. The correct option is D.
What is genetic diversity?The spectrum of various inherited traits inside a species is referred to as genetic diversity.
There would be many individuals with a wide range of different traits in a species with high genetic diversity. For a group of related species to adapt to changing environments, genetic diversity is mandatory.
Genetic diversity aids the populations to adapt to altering environments. More variation boosts the likelihood that some individuals in a population will have allele variations that are suited to the environment. Those people are more likely to survive and have children with that allele.
Birds can produce an optimal number of eggs due to genetic diversity, which leads to stabilizing selection.
Thus, the correct option is D.
