The arctic fox has a diploid number of 50 an arctic fox was forming gametes by meiosis, how many chromosomes would be visible in prophase 17 Are the chromosomes replicated or non-replicated?
a. 2. 50; unreplicated
b. 28; replicated
c. 100, replicated
d. 25: unreplicated
e. 6.50; Replicated

Answers

Answer:

50 visible chromosomes and replicated.

Explanation:

Diploid number 50Haploid number 25

When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).

Interphase is composed of stages G1, S, and G2. During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.

Meiosis occurs after the interphase is over.

Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.

At the beginning of prophase 1, DNI is condensed in a well-defined chromosome formed by two sister chromatids joined by a centromere. Each chromosome carefully pairs with its homologous chromosome. Homologous chromosomes aline together to make the crossing-over possible, the stage where they interchange their parts.

The whole set of chromosomes is present in prophase 1. The reduction occurs later.

So if the germ cell has 50 chromosomes, the same 50 will be visible during prophase 1. DNA has already been replicated during the S stage of interphase.

What is the process in the cell can be disturbed by the destruction of the mitochondria?


a.
nuclear fission

b.
photosynthesis

c.
oxidation of substances organic

d.
crossing-ove

Answers

Answer:

The correct answer is - C. oxidation of substances organic.

Explanation:

The major function of the mitochondria is to perform cellular respiration and produce energy in the form of ATP by oxidating organic molecules. All the process requires energy to be processed, however, the main and primary process that would disturb if by the destruction of the mitochondria occur which is the oxidation of glucose to convert it to pyruvic acid to generate energy.

The Krebs cycle that takes place in mitochondria and performs oxidation of organic molecules will also be disturbed and there will be no energy for any process.

olecular diagnostic techniques that can help diagnose hemoglobin disorders such as hemoglobinopathies and thalassemias include a) biochemical separation, identification, and quantification of mixture components b) separation of macromolecules and their fragments, based on their size and charge c) DNA amplification, hybridization, and nucleotide sequencing d) The use of specific monoclonal antibodies

Answers

Answer:

The correct answer is - a) biochemical separation, identification, and quantification of mixture components.

Explanation:

Most hemoglobin disorders can be diagnosed by molecular diagnostic techniques such as protein-based techniques like electrophoresis and chromatography. Protein-based methods can diagnose early thalassemia disorders and hemoglobinopathies but in the case of α-thalassemia may be masked in the presence of β-thalassemia.

Molecular genetic testing plays a very important role in the biochemical separation of molecules or components, identification, and quantification of individuals carrying thalassemia and hemoglobinopathies traits and other hemoglobin disorders.

Her eyes are wide-set and slightly slanted. Her nose is short and flat, and she keeps her mouth slightly open. There is a straight crease across her palm, and her fifth digit is unusually short. The doctor tells her parents she has an inherited disorder. If you were the doctor what would you diagnosis Kate with? Discuss the etiology of Kate’s disorder? What is the biggest risk factor for this disorder? How can or will this disorder affect Kate? What test could have been completed to diagnosis this disorder before Kate’s birth?

Answers

Answer:

- These morphological features belong to Down syndrome.

- Diagnosis: Down syndrome (Trisomy Extra chromosome 21).

- Etiology: the presence of three copies of the autosomal chromosome 21 instead of two copies in body (somatic) cells.

- Most important health problem: Down syndrome increases the risk of developing Alzheimer's disease (other health problems include heart congenital defects, vision problems, hearing loss, hypothyroidism)

- Diagnostic test: Amniocentesis

Explanation:

Down syndrome (DS) is the most frequent chromosomal abnormality which is generally caused by the presence of an extra copy of autosomal chromosome 21, thereby it is an autosomal trisomy (trisomy 21). DS is often associated with intellectual disability and increased risk of developing Alzheimer's, as well as health problems including, among others, heart congenital defects, vision problems, hypothyroidism, blood disorders, hypotonia, endocrine problems, dental problems, seizures, etc. Amniocentesis is the most common invasive prenatal diagnostic procedure which is used to identify chromosomal abnormalities such as trisomy 21 (Down syndrome). Amniocentesis is done between 15 weeks and 20 weeks of pregnancy.

DDT is an insecticide that accumulates in the fatty tissues of animals whose concentration increases with each link of the food chain. Which group of organisms is most likely to accumulate the highest concentration of DDT?

Answers

The question is incomplete, the complete question is shown in the image attached

Answer:

D

Explanation:

Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.

Also, tend to increase in the fatty tissues of organisms at each trophic level.

Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.

Estimate the sum of the masses: 56.9kg, 43.9kg, 60.5kg, 29.8kg​

Answers

Answer:

191.1 kg.

Explanation:

The total mass of all these objects can be determined by adding all the masses present in the question. 191.1 kg is the value of total masses when the given masses such as 56.9kg, 43.9kg, 60.5kg and 29.8kg​ are added with each other. This value is considered as the total sum of all masses so we can say that the total value is obtained after all the masses are combine or added together.

How does carbon dioxide travel in blood via dissolved form

Answers

Answer:

carbon dioxide is more soluble in water than oxygen and hence is mostly transported in the dissolved form in our blood.

Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.

The majority of carbon dioxide is transported as part of the bicarbonate system.
