Part B - Relationship between population size and growth rate
A population of animals in a specific environment with a K of 2500 has rmax of 1.0 per individual per year and exhibits logistic growth as follows:
dN/dt}=rmax.N.(K-N)/K
Arrange the following population sizes in order of decreasing growth rate.
Rank the population sizes(N)from fastest to slowest growth rate. If two population sizes have the same growth rate, overlap them. (For help calculating growth rate, see Hint 1.)

Answers

Answer 1

Arrangement of the population sizes in the order of decreasing growth rate 1250> 1000 = 1500(same growth rate) > 750> 500> 250.

More and more of the offspring will survive if the rate of growth increases. As a result, there is a cumulative effect in which the slope gets steeper as the growth rate increases.

growth rate is given by as dN/dt=rmax.N.(K-N)/K

where r = 1.0 and K = 2500 are constant

at N = 750  

dN/dt = 0.1 × 750 × (2500-750)/2500

= 52.5

at N = 500

dN/dt = 0.1 × 500 × (2500-500)/2500

= 40

at N = 1000

dN/dt = 0.1 × 1000 × (2500-1000)/2500

= 60.0

at N = 1250

dN/dt = 0.1 × 1250 × (2500-1250)/2500

= 62.5

at N = 250

dN/dt = 0.1 × 250 × (2500-250)/2500

= 22.5

at N = 1500

dN/dt = 0.1 × 1500 × (2500-1500)/2500

= 60

the more value of dN/dt, the more will be the growth rate.

hence, 1250> 1000 = 1500(same growth rate) > 750> 500> 250.

A. He crossed true-breeding pea plants.
B. He allowed eggs to be fertilized only by self-pollination.
C. He analyzed his data mathematically.
D. He controlled variables by studying one or two traits at a time.

Answers

A. He crossed true-breeding pea plants

The research practices Mendel used is applies including A, B and C.

What is Mendel's experiment?

Mendel studied inheritance in peas (Pisum sativum). He chose peas because pea plant are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and can usually self-pollinate.

Mendel studied the inheritance of 7 traits in pea plants including height, flower color, seed color, and seed shape and each trait had 2 forms. He identified pure-breeding pea plants that consistently showed 1 form of a trait after generations of self-pollination.

Mendel proposed a theory of inheritance, based upon the observed data during his experiments, and a mathematical analysis of his results,

Thus, from above, the correct options include A, B and C whereas D doesnt apply because Mendel studied 7 traits at a time.

Answers

Answer:

The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: thyroid gland.

The largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.

What do you mean by Endocrine Gland?

An endocrine gland may be defined as a type of gland which consists of several organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body. These hormones control many important functions in the body, including growth and development, metabolism, and reproduction.

The pancreas is the largest endocrine gland that significantly makes three hormones namely, Insulin, Glucagon, and Somatostatin. These hormones are actively involved in the regulation of metabolism by numerous mechanisms.

For example, insulin lowers the level of sugar in the blood, while glucagon increases the level of sugar by transforming its storage form.

Therefore, the largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.

Identify the true statements regarding liver glycogen phosphorylase a. Protein phosphatase 1 is abbreviated PP1. The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form to the inactive form. Liver phosphorylase a concentration decreases when glucose enters the blood. As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. Liver phosphorylase a is regulated by AMP, adenosine monophosphate. When PP1 is bound to phosphorylase a, both PP1 and phosphorylase a are active.

Answers

Answer:

Liver phosphorylase a concentration decreases when glucose enters the blood.

The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form

As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form

Explanation:

Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase a is converted (and inactivated) into the b form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase a, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase a.

a. recombination is never observed because coral and cherry are in the same complementation group
b. recombination is impossible because they are in the same gene (white)
c. recombination is never observed because coral and cherry display the same phenotype
d. recombination is possible and can generate a wild-type allele and a double mutant allele

Answers

Answer:

Recombination is possible and can generate a wild-type allele and a double mutant allele ( D )

Explanation:

The true statement regarding the recombination between the alleles is : Recombination is possible and can generate a wild-type allele and a double mutant allele.

The recombination process involves the breaking and recombination of pieces of DNA in order to produce new alleles. this recombination ( crossover ) results to the offspring possessing different combination of genes ( wild -type allele and double mutant allele ).  hence option D is the correct answer.

tRNA

Explanation:

The given sequence is RNA sequence as it contains uracil in the sequence instead of thymine. In this sequence, there are nucleotides under 100 so it's comparatively small for mRNA molecules.

Therefore it is a single-stranded RNA molecule with a distinctive cloverleaf structure which is a characteristic feature of the tRNA molecule that is used to make amino acids sequences with the help of mRNA during translation.

Explanation:

Hence, abiotic elements determine how organisms survive in an ecosystem. The main difference between biotic and abiotic is that biotic refers to all living things of an ecosystem while abiotic refers to all the non-living, physical and chemical things of an ecosystem.

Sunlight, rocks, and soil are all non-living.

The only biotic component mentioned is bacteria. Living things or their impacts are referred to as biotic factors. Single-celled creatures known as bacteria can live alone or in colonies.

They may be found almost anywhere, including the soil and the human body. All three kingdoms of life, Archaea, Bacteria, and Eukarya, contain bacteria that can reproduce. The terms "soil," "sunlight," and "rocks" all refer to abiotic elements, or nonliving parts of the environment.

Minerals, organic substances, gases, liquids, and living things all make up soil. Photosynthesis and other biological activities require sunlight, a type of energy that the sun radiates. Rocks are unbreakable, inorganic objects made of minerals.

e) make eggs or sperm, and only germ-line cells do it

Answers

Answer:

A) make new cells(somatic cells)and only germ-line cells do it(meiosis)

Explanation:

Meiosis is the process through which germ cells that produce gametes such as sperm and eggs are formed. It is an equatorial division that involves the parental cell dividing into daughter cells each containing similar genetic material as the parents cell and this can be passed on to successive generation.

While Somatic cells are cells that form the building blocks of the body, they are the actively divided body part and only divide by mitosis.

Meiosis produces germ cells while mitosis produces somatic cells.

They write so that their work can be portrayed on the theatrical stage and can be seen by an audience. For many writers, having their work shown on the Broadway or London stage is a triumph. However, success on the stage can be fleeting for some playwrights. On Broadway, plays and musicals sometimes only last for a few weeks. Harsh critics can damage the play's reputation and make it difficult for the play to find an audience. But, for the lucky few playwrights, their work can last for years. Neil Simon is one of the fortunate playwrights to achieve major success on Broadway. In 1961, Come Blow Your Horn was Simon's first play to open on Broadway. It ran for 678 performances at the Brooks Atkinson Theatre. Following this achievement, Simon had four shows running simultaneously in 1966. The shows were Sweet Charity, The Odd Couple, The Star-Spangled Girl, and Barefoot in the Park. Simon's writing for Lost in Yonkers even gave him the Pulitzer Prize for Drama in 1991. The play focused on the dynamics of a family living in Yonkers, New York. It also showed how the family members negatively affected each other. In addition, to Simon's success on Broadway, he also was a notable screenwriter. He adapted many of his plays into film. Simon's The Odd Couple was one of his winning adaptations. The storyline has become a part of popular culture. It was a hit on Broadway because the story focused on two mismatched roommates, who live with each other after their divorces. They were originally played by Art Carney and Walter Matthau. Following that, Simon wrote the script so that the play could be translated onto the big screen. Because of its popularity, the play's concept also became a television series, which lasted five years. The show aired on ABC with minor changes from the play. The television scripts were not written by Simon himself. There are still few revivals of The Odd Couple on the stage and in television.Which detail from the passage supports the claim that Neil Simon achieved success in different media? A.
