Answer:

“Hard limits” to population growth are things like food, water, energy, technology, living space, other basic needs and economic factors which limit people’s ability to access these things.

“Soft limits” to population growth are things like education, birth control, the desire for a better life individually and a better global future for humanity, religious celibacy or chastity or abstinence, female empowerment and economic participation, the suffering already caused by overpopulation and the desire to avoid further suffering, malnutrition or non-lethal starvation which reduces sexual libido, pollution and other man made causes of involuntary sterility or low sperm count or low fertility, desire to save the environment, aversion to pain and suffering when understood that population growth causes both.

Countries with better quality of life and access to food and basic needs often have lower birth rates and lower population growth. This shows that soft limits can actually be more effective than hard limits to stop population growth. You have plenty of countries in Africa running into hard limits and having some of the highest fertility and population growth rates at the same time. They also suffer massive problems like war, poverty, disease and low standard of living. This goes to show that running into the hard limits will pretty much let things get as bad as they can get before it stops population growth. The hard limits won’t stop all the suffering caused by overpopulation but will make enough people suffer TO DEATH that the population doesn’t grow. People fear pain, thus the soft limits are more effective when they understand that population growth was responsible for pain or suffering and avoid it.

A student is given a list of traits and is asked to organize them in a Venn diagram as shown below.

Which traits should the student put in section II (Both)?
1 a scar and blood type
2 tiger's stripes and wolf's social status
3 musical talent and wolf's social status
4 musical talent and skin color

Answers

Answer: The correct answer is option B) a scar and wolf's social status.

The acquired traits can be defined as the traits, which are only influenced by the environment of the organism. The acquired trait cannot be passed down to the offspring, as they are not genetically determined. A scar and the social status of any organism is dependent on the behavior of the organism to the environment, no genes code for both of these characters. So, scars and Wolf's social status is an acquired trait.

The cell cycle is the life of the cell from the time it is first formed from a dividing parent cell until its own division into two cells

Answers

Explanation:

cell cycle is made up of three main parts: interphase, mitosis, and cytokinesis. Most biologists agree that interphase makes up the period of time that a cell would be preparing for cell division. Cells spend the majority of their lives in this stage. During interphase a cell is going to be growing, replicating its genetic material and essentials to carry out cell division, and proofreading the genetic material to ensure replication has occurred correctly. This doesn’t sound like much, but it’s actually the longest part of the cell cycle. Once this is complete, the cell will then go through cell division and, theoretically, split into two new cells (cytokinesis).

How cytokinesis works will depend upon the type of cell that is dividing. Here is an image that summarizes the differences in cytokinesis in plant cells and animal cells, which is the classic example used in many introductory biology courses:

A. Chromatin, DNA, Chromatin, nucleosomes
B. Chromosomes,DNA, Chromatin, nucleosomes
C.DNA, nucleosomes, chromatin, chromosomes
D. Nucleosomes, DNA, chromatin, chromosomes

3. In a triploid organism, how many alleles are present for each gene per cell?
A. 1
B. 3
C. 6
D. 9

Answers

I) Independent assortment.

II) Nucleosomes, DNA, chromatin, chromosomes.

III) 3.

EXPLANATION:

Recombination scrambles pieces of maternal and paternal genes, which ensures that genes assort independently from one another.

➻ We know that Chromatin is a complex of DNA and proteins that forms chromosomes. Chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA.

Triploids with three different alleles can easily be detected because they have a unique phenotype.

The process involved in genetic recombination is INDEPENDENT ASSORTMENT. The correct order from smallest to largest is DNA, nucleosomes, chromatin, chromosomes. In a triploid organism, there are 3 ALLELES for each gene.

In independent assortment, different gene variants or 'alleles' are independently and randomly assorted into daughter cells, which allows genetic recombination.

In eukaryotic organisms, DNA is associated with histone proteins in order to form nucleosomes, which arrange in higher organization structures called chromatin fibers.

Subsequently, chromatin fibers condense to form structures called chromosomes.

A triploid organism (3n) contains three sets of homo-logous chromosomes, each one containing one allele for a given locus.

In conclusion, the process involved in genetic recombination is INDEPENDENT ASSORTMENT. The correct order from smallest to largest is DNA, nucleosomes, chromatin, chromosomes. In a triploid organism, there are 3 ALLELES for each gene per cell.

What is Cell wall?

Cell walls are a specific type of extracellular matrix that cover every plant cell. Many of the traits that set plant cells apart from animal cells are caused by the cell wall.

The cell wall serves a variety of activities that are essential to plant life, despite being frequently thought of as an inert product used only for mechanical and structural purposes.

These include:  giving the living cell mechanical defense and a chemically insulated environment; offering a porous medium for the circulation and distribution of water, minerals, and other small nutrient molecules.

Organisms of either extreme characteristic dying out while organisms with the medium characteristic have a higher fitness is identified as?

Answers

Answer: Stabilization selection

Explanation:

Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.

El intestino delgado es el organi mas largo del tubo digestivo, pudiendo medir 7 metros de longitud y 3 cm de diametro. Se caracteriza por estar sumamente plegado sobre si mismo. La primera porcion, llamada duodeno, recibe secresiones de glándulas biliar y pancreática, y las mezcla con enzimas digestivas. Esta mezcla se encarga de degradar la comida y transformarla en sustancias solubles, como amino ácidos.

Es en el intestino delgado donde ocurre la absorción de nutrientes.  Las paredes intestinales estas cubiertas por microvellosidades que aumentan la superficie de absorción.  

Las microvellosidades son células que componene el epitelio columnar, y que extienden proyecciones hacia el lumen del organo.

A 38-year-old mother of three presents to her primary care office with complaints of fatigue. She feels that her energy level has been low for the past 3 months. She was previously healthy and taking no medications. She does report that she has gained about 10 lb and has severe constipation, for which she has been taking a number of laxatives. A TSH is elevated at 25 mU/L. Free T4 is low. She is wondering why she has hypothyroidism. Which of the following tests is most likely to diagnose the etiology?
A. Antithyroid peroxidase antibody
B. Antithyroglobulin antibody
C. Radioiodine uptake scan
D. Serum thyroglobulin level
E. Thyroid ultrasound

Answers

Answer:

A. Antithyroid peroxidase antibody

Explanation:

The most common cause of hypothyroidism is autoimmune thyroiditis, also known as chronic lymphocytic thyroiditis or Hashimoto's disease. This condition (autoimmune thyroiditis) is caused by damage of the thyroid gland, which occurs when antibodies of the immune system attack this gland. The thyroid peroxidase test is an enzyme immunoassay widely used to measure the level of autoantibodies against thyroid peroxidase. Patients with chronic thyroiditis often display a positive thyroid peroxidase test. On the other hand, thyroid ultrasound is useful for the initial evaluation of painless thyroiditis in order to distinguish nodules or multinodular goiter. Antithyroid peroxidase antibodies are commonly observed in individuals suffering autoimmune thyroiditis, whereas antithyroglobulin antibodies are observed in different thyroid disorders and autoimmune diseases. Finally, a radioiodine uptake scan measures the amount of radioactive iodine accumulated in the thyroid gland, which is useful only for diagnosing early‐stage of Hashimoto's thyroiditis.
