In Drosophila, the genes r and s are linked. Flies of genotype r s/r s and rs /rs are crossed and an F1 obtained. The F1 allele arrangement is called:

Answers

Answer 1

Answer:

repulsion (trans)

Explanation:

Repulsion refers to the phenomenon by which each homologous chromosome contains one dominant and one recessive allele from two different linked genes. A trans arrangement occurs when an individual is heterozygous for two linked genes, where the recessive allele for one particular gene is located on the same chromosome as the dominant allele for the other linked gene, thereby dominant and recessive alleles are said to be “in repulsion”. Conversely, a cis arrangement occurs when both dominant alleles are located on one chromosome and both recessive alleles on the other.

atmosphere is a present around the surface of the earth but it is not present around the surface of the Moon why​

Answers

Answer:

tmosphere is a present around the surface of the earth but it is not present around the surface of the Moon because

This reduces the amount of gravity on the moon. Strong gravity is needed to hold an atmosphere into place. With weak gravity, gases that are emitted from the surface quickly are lost to outer space. Another reason is because the moon does not currently experience plate tectonics and geologic upwelling. Plate tectonics allows for a recycling of crust and convergence and divergence of plates occurs and this leads to volcanoes and gases escaping at the boundaries. The moon is said to be geologically dead.

Hemochromatosis is an inherited disease caused by recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability of all three children having a normal phenotype

Answers

Answer:

27⁄64

Explanation:

A recessive disease is expressed only when an individual carries two copies of the recessive allele (i.e., individuals must be recessive homo-zygous to suffer from the disease). In this case, both parents are carriers for hemochromatosis, i.e., both are heterozygotes carrying the defective allele, thereby the probability of having a child with a normal 'dominant' phenotype is 3/4, i.e., 3/4 individuals are expected to have an A_ genotype (1/2 AA + 1/4 Aa = 3/4), and 1/4 individuals are expected to have an aa genotype (where 'A' is the dominant allele and 'a' is the recessive allele associated with hemochromatosis). In consequence, the probability of having three children with the normal phenotype is 3/4 x 3/4 x 3/4 = 27/64.

what impact are these practices expected to have on soil pH and why?​

Answers

Inherent factors that affect soil pH include climate, mineral content, and soil texture. Natural soil pH reflects the combined effects of the soil-forming factors (parent material, time, relief or topography, climate, and organisms). The pH of newly formed soils is determined by the minerals in the parent material.

In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used for specific purposes when studying cells and tissues, and even whole organisms. This microscope is called a scanning electron microscope (SEM). Use your lab manual, its support resources, and/or the Internet to investigate the use of scanning electron microscopy for biological applications. After gathering this information, please answer the following question. When would it be appropriate to use the SEM rather than the TEM

Answers

Answer:

The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.

SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.

Explanation:

The laryngeal reflex occurs and it is present in babies after birth. When water occupies or enters the mouth, the laryngeal reaction is triggered. While your infant is underwater, the glottis and epiglottis shut, keeping water from penetrating the throat(larynx and pharynx) and establishing a watertight barrier to the lungs. This is so to prevent the aspiration of water into the lungs.

Answers

Answer:

VII. Anaphase II

Explanation:

During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach Anaphase II, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole

The Metamorphosisby Franz Kafka (excerpt)The flight of the chief clerk seemed, unfortunately, to put Gregor's father into a panic as well. Until then he had been relatively self controlled, but now, instead of running after the chief clerk himself, or at least not impeding Gregor as he ran after him, Gregor's father seized the chief clerk's stick in his right hand (the chief clerk had left it behind on a chair, along with his hat and overcoat), picked up a large newspaper from the table with his left, and used them to drive Gregor back into his room, stamping his foot at him as he went. Gregor's appeals to his father were of no help, his appeals were simply not understood, however much he humbly turned his head his father merely stamped his foot all the harder. Across the room, despite the chilly weather, Gregor's mother had pulled open a window, leant far out of it and pressed her hands to her face. A strong draught of air flew in from the street towards the stairway, the curtains flew up, the newspapers on the table fluttered and some of them were blown onto the floor. Nothing would stop Gregors father as he drove him back, making hissing noises at him like a wild man. Gregor had never had any practice in moving backwards and was only able to go very slowly. If Gregor had only been allowed to turn round he would have been back in his room straight away, but he was afraid that if he took the time to do that his father would become impatient, and there was the threat of a lethal blow to his back or head from the stick in his father's hand any moment.14Select all the correct answers.Based on the passage, which of the following best describes how Gregor feels now that he has become a giant insect?Gregor needs to be left alone now that he is no longer human.Gregor finds it difficult to adjust to his new insect body.Gregor feels the needs to be accepted by his family as he is.Gregor is scared of his father and unable to communicate with his family.Gregor is sad because he is unable to transform back to human form. pls help asap if your good at history the currency of cuba isthe capital of cuba isCuban national anthem iscuba is the largest______in the Caribbean seawhat dances are the passion of cubans verify that csc cos tan =1 A screening test for a disease shows a positive result in 91% of all cases when the disease is actually present and in 7% of all cases when it is not.
