A pure-breeding, tall pea plant with white flowers is crossed with a pure-breeding, short plant with red flowers. The F1 plants are tall, with red flowers. When allowed to fertilize themselves, these produce the following F2: 326 tall, red; 104 tall, white; 117 short, red; and 29 short, white. You are conducting a Chi-Square analysis and what is the null hypothesis?
Answers
Answer:
Null Hypothesis -
The observed frequency is approximately equal to the expected frequency of phenotype.
Explanation:
Pure Breeding Cross - TTww x ttWW
Genotype of offspring in F2 generation - TtWw
Null Hypothesis -
The observed frequency is approximately equal to the expected frequency of phenotype.
The chi square analysis is attached
The degree of freedom for this question is 3
The p value for X^2 estimated through chi square test is 0.5
Hence the null hypothesis is accepted.

If an organism inherits 1 dominant allele from one parent and 1 recessive allele from the other parent, what is it called?
Answers
Answer:
heterozygous
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. Genotypes are described as heterozygous if the two alleles differ.
Which location has the warmer air temperature: Tarapoto or Neuquén? Why?
view the pic below.
Answers
Answer:
Palmas is closer to the equator than Neuquén. Which location has a warmer air temperature.Neuquén, because more energy is transferred from the sun directly to the air. Neuquén, because more energy is transferred from the sun directly to the surface, and then from the surface to the air.
Answer:
The climate in Tarapoto is hot, muggy, and mostly cloudy. Over the course of the year, the temperature typically varies from 70°F to 94°F and is rarely below 67°F or above 98°F.
And that is why the neuquen has the warmer air temperature!

whooping crane
3.How are Burmese pythons and whooping cranes similar?(1 point)
Both species were relocated to new environments as pets.
Both species’ populations were affected by human actions that caused environmental changes.
Both species’ populations were almost wiped out because of a variety of environmental changes.
Both species became top predators in their new environments.
4.A student is conducting research on the impact of humans on whooping crane populations in the North America. Which statement best supports the student’s claim that animals have been positively impacted by human intervention?(1 point)
Captive-bred whooping cranes have been introduced to natural environments.
In the 1800s, North America was home to over 1,000 whooping cranes.
In the early 1900s, the U.S. and Canada jointly signed a migratory bird treaty.
Although the hunting of whooping cranes was criminalized, their numbers continued to decline.
Answers
Explanation:
1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g dramatically increasing turtle population.
2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.
3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.
Climate change leads to salinity, the python is responsible, the populations were affected due to human actions that caused environmental changes. In the early 19th, America and Canada signed a migratory bird treaty.
What is the explanation of the above answers. ?The Everglades is a wetland preserve of southern Florida and is made up of coastal mangroves. Due to the impacts of the climate the region is under threat from the rising seawater and hence salinity is also one of the factors that are due to climate change.
The python is a species that is responsible for the 99% for drop in the level of the possum population of the everglades. The native Burmese's python is a cause of animal decline they are similar to the cranes because both of them are wiped by the environmental changes made by man.
As per the research of the student the impact of human whooping cranes in North America is due to the early 19th century both the US and Canada signed the migratory bird treaty.

Hemoglobin is the protein that transports oxygen in mammals. Different species of mammals have slightly different forms of hemoglobin. One form of hemoglobin is 0.324% Fe by mass, and each hemoglobin molecule contains four iron atoms. Calculate the molar mass of this form of hemoglobin. Make sure to include units of g/mol. Enter your answer in Scientific notation with three significant figures. The Scientific notation for 2 x 10-4 would be written as 2E-4.
Answers
Answer:
The correct answer is - 6.8950.61 gm per mole
Explanation:
Given:
One form of hemoglobin is 0.324% Fe by mass
1 hemoglobin = 4 Fe
Solution:
Molar Mass of iron = 55.85
mass of 4 iron atom = 55.85 * 4 = 223.4 gms
0.324 % correspond to 223.4 gms
100 % correspond to = 223.4 *100/0.324
= 68950.61 gm
MM of haemoglobin = 68950.61 gms = 6.8 E4 gms

Human DNA DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA RNA GGU GLY Amino acid Cow DNA DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC RNA Amino acid
Answers
Answer:
Please find the complete table attached as an image
Explanation:
This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).
- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.
- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.
The table has been completed and attached below. Note that in the amino acids row;
GLY means Glycine
ILE means Isoleucine
VAL means Valine
GLN means Glutamine
CYS means Cysteine
THR means Threonine
SER means Serine
PHE means Phenylalanine
ALA means Alanine
LEU means Leucine

Explain why siblings may share similarities but are not identical.
Answers
Answer:
recombination
Explanation:
Since of recombination, kin as it were share approximately 50 percent of the same DNA, on normal. So whereas organic kin have the same family tree, their hereditary code can be distinctive in at slightest one of the zones looked at in a given test. That's genuine indeed for intimate twins.
Siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.
What is the reason behind a non-identical sibling?Siblings are not identical because each parent can contribute different variations of genes to each child, resulting in unique combinations of genetic material. Moreover, the process of meiosis, which is the formation of reproductive cells, is a random process, meaning that the chromosomes from each parent can mix in different ways during the formation of the offspring's cells. Therefore, each sibling inherits a unique combination of genetic material, leading to individual differences in physical and behavioral traits.
Hence, siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.
