When a red flowered pea plant was crossed with a white flowered pea plant, it was found that all plants in the F1generation carried only red flowers. If these plants are self crossed, i) Find the genotypic ratio that we can expect in F2 generation ii) What is the phenotype and genotype of F1 generation. Draw Punnett square for F2
Answers
Answer:
The correct answer is -
i) genotype of F2 - 1:2:1 = dominant:heterozygous:recessive
ii) genotype of F1 - all heterozygous dominant
phenotype - all red
Explanation:
In the cross of red- flowered plant and white flowered plant the offspring produces red flowers that s only possible if the parent red flower plant has both alleles in dominant condition.
For the F1 the gametes will be R, R and r, r
from the Punnett square, we can see all the offspring are heterozygous (Rr) in genotype and red in phenotype
For F2 the gametes will be - R, r, and R, r
From the punnet square, the genotype we get is 1:2:1 = dominant:heterozygous:recessive

There was a nearly intact fossil of a hadrosaur called Dakota. How did this find change our knowledge of the hadrosaur? List three specific ways.
Answers
Answer: Environment, skin coating, and perhaps seasonal migration.
Explanation: The hadrosaur has become an unmistakable species due to its unusual bill, and bipedal legs. However this new fossil could change many studies. First off, environmental hazards. Due to the amount of carnivorous fossils found in the Dakota area, finding a nearly intact fossil of any sort should be quite impossible. This brings paleontologists to believe hadrosaurs may have had some sort of defense against predators, which brings us to skin coating. To be found in such an arctic area must have meant it would be difficult for anything herbivorous to live in the area, unless feathers, or fur was involved. This could change every theory about the so called scaly beasts we refer to as dinosaurs. This brings us to our final topic, migration. Every winter if you were to go outside, it would be highly unlikely to hear birds. This is known as migration, a period when certain animals of multiple species, typically birds, move to warmer areas for the winter. Consider if the birds descending from dinosaurs theory was correct. This could in fact be how birds somehow get this preconceived notion to migrate. This, just as wild dogs are naturally aggressive, could be instinct.
4. The two major threats of burns are?
a. Loss of skin and infection
b. Dehydration and Discoloration
c. Discoloration and Loss of Skin
d. Infection and Dehydration
Answers
Answer:
A
Explanation:
Id say A because dehydration has to do with the lack of water, and we are talking about burns. Discoloration might make sense in context such as the skin around the burn was dark and discolored. But actually loosing your skin and getting an infection in that open wound sounds much worse
Why is there variation (differences) between the phenotypes of our protein pals?
*Use the following terms in your answer: Nitrogen Bases, DNA, Protein*
Answers
Answer:
Explanation:
Proteins are large molecules made from amino acid. During protein synthesis, a sequence of three DNA or mRNA nucleotides (that are usually denoted with the nitrogenous bases of the nucleotides) correspond to different amino acids. These sequence of three are called codons which eventually code for different amino acids and the amino acid sequence, on its own, forms proteins. Different amino acid sequence forms different proteins thus leading to phenotypic variation of our protein as said in the question

John observed that left over pineapple kept at 15 oC in the refrigerator tastes sweater than pineapple consumed just after being peeled (at room temperature). He thinks that this occurs because of an enzyme which acts at the lower temperature to hydrolyze the stored sucrose to glucose and sucrose
Answers
Answer:
No, John is wrong.
Explanation:
Pineapples are one of the popular fruits among people and people eat pineapple when they are ripen. It tastes sweet and juicy. But unlike most of the other fruits, pineapple does not ripe once it is plucked. It tastes very sweet when it is properly ripen.
In the context, John kept the left over pineapple in the fridge at about 15 degree Celsius and he found that the pineapple tastes sweeter the, This is because the sugary juices from the parts that is ripen trickles and spreads to all the parts of the fruit. So it tastes sweeter. It is not because of any enzymes.

How would you difference between pollen cells and algae cells?
Answers
Answer:
The difference between the given terms is summarized below.
Explanation:
Pollen cells:
Single or perhaps even more vegetative cell lines as well as a reproductive cell come in the form of pollen. The masculine gamete is not a pollen crop on its own.Algae cells:
There will only be a singular nucleus throughout many of these algal cells, whereas other cells have become multi-nucleate. Furthermore, several other algae were indeed saponaceous, which means that cell walls aren't differentiated from one of the several nuclei.The differentiation between pollen cells and algae cells can be seen from the habitat in which they thrive and their structural characteristics.
The pollen cells are reproductive structures in a plant that gives rise to the male gametophyte that houses the male reproductive cell of a plant. During pollination, they are being transferred to the stigma by to the presence of spikes around the pollen cells which attaches to the bees (an agent of pollination).
The algae cells are single or multinucleate eukaryotic cells, that live in swampy and wet habitats. The presence of the tail in the cells helps in the locomotion of the cells to the area where their fertilization takes place.

b. they would look like Y chromosomes
c. the distribution of genetic material into separate daughter cells may not occur equitably
d. it would not take as long for mitosis and meiosis to occur
Answers
Answer:
c. the distribution of genetic material into separate daughter cells may not occur equitably
Explanation:
Deoxyribonucleic acid, also known as DNA, is the genetic material in living organisms. It is found in the nucleus of eukaryotic cells. The DNA is, however, found to be wrapped around certain proteins to form an X-shaped CHROMOSOME structure during the process of cell division (mitosis and meiosis).
The purpose of this shape is to ensure that the daughter cells that results from cellular division processes receives an equal copy of the DNA in each chromosome. Hence, If DNA were not packed into X-shaped chromosomes, the distribution of genetic material (DNA) into separate daughter cells may not occur equitably/equally.

Infiltration is the process in which the water seeps into the soil surface. Thus, option B is correct.
What is Infiltration?Infiltration is an important phenomenon that defines percolation of water in the soil. It is important for maintaining the ground water level.
The water seeps down into the soil gradually through capillary action. Infiltration is mostly observed during a rainfall.
Infiltration takes place till the soil accomodates maximum water. Beyond that, infiltration will stop as the soil is said to be saturated with water.
Infiltration is measured in inches per hour. It is the depth of water enters into the soil in an hour.
Infiltration rate is determined by various factors. Soil porosity and texture of the soil is one such important factor for water infiltration.
Porosity of the soil can be deteriorated through human activities. Large pores hinder percolation of water.
Infiltration is also determined by the intensity and duration of precipitation.
Therefore, infiltration is important for increasing the water table for further water storage.

С

D insects, myriapods, nematodes
Answers
Answer:
Arachnids, crustaceans, myriapods.
Explanation:
Arthropods are animals that form the phylum Euarthropoda. This phylum includes the arachnids, crustaceans, myriapods, and insects. The defining characteristic for an animal to be considered an arthropod is that it has to have an exoskeleton, meaning that the skeleton of the animal is acting as a shell to the body, covering it from the outside.
At present, all of the species of arthropods are small in size, though in the distant past there were speciemens that can be considered as medium-sized or even large. The exoskeleton has its advantages and disadvantages. An advantage is that it is very hard and it covers fully the internal organs, thus protecting them. A disadvantage is that it limits the size to which these animals can grow as the exoskeleton cannot support the weight of the body after certain point.
