In an experiment, Tony placed a potted plant under a bell jar, completely sealing the jar to the table top. After placing a box over the bell jar for 24 hours, he measured the concentrations of oxygen and carbon dioxide in the gas in the jar. Which statement BEST describes the measurements he would find in the jar, compared with the concentrations of oxygen and carbon dioxide in the classroom air?

A. Oxygen concentration increased, carbon dioxide concentration decreased.
B. Dioxide concentration increased; oxygen concentration decreased.
C. Concentrations of both carbon dioxide and oxygen decreased.
D. Concentrations of both carbon dioxide and oxygen increased.

Answers

Answer 1
Final answer:

In Tony's experiment, the plant was undergoing respiration in the dark for 24 hours, absorbing oxygen and releasing carbon dioxide. This would lead to a decrease in oxygen concentration and an increase in carbon dioxide concentration in the jar.

Explanation:

In Tony's experiment, the potted plant enclosed inside a bell jar was subject to a process called photosynthesis during the day and respiration during the evening. During photosynthesis, plants absorb carbon dioxide (CO2) and release oxygen (O2) to the environment. In contrast, during the respiration process, plants absorb O2 and release CO2, a process which continues even during the night. Considering the setup of Tony's experiment, the plant was in darkness for 24 hours, which means it was only undergoing respiration.

Based on these factors, the correct statement describing the measurements Tony would find in the jar is: Oxygen concentration decreased, carbon dioxide concentration increased. This is simply because, during respiration, the plant would be using up the available oxygen and releasing more carbon dioxide in the sealed jar, leading to a decrease in oxygen concentration and an increase in carbon dioxide concentration. This change would be relative to the initial measurements in the classroom environment.

If the concentration of a sugar solution is lower outside the cell than inside the cell, which will happen by osmosis?

Answers

The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. ... On the other extreme, a red blood cell that is hypotonic (lower concentration outside the cell) will result in more water flowing into the cell than out.

Answer:

Water molecules will move out of the cell

Explanation:

We are given that the concentration of a sugar solution is lower outside the cell than inside the cell. This means that a concentration gradient of water now exists across the membrane.

In Osmosis, we know that water molecules move from a less concentrated solution into a more concentrated one.

So in this case, water molecules will move out of the cell.

8) What are the differences between asexual reproduction and sexual reproduction?
A) Offspring are produced only by sexual reproduction.
B) An exchange of genetic material only occurs with asexual reproduction. C) Sexual reproduction involves one parent organism, while asexual involves two parent organisms.
D) Asexual reproduction produces offspring identical to the parents, while sexual reproduction produces offspring different from the parents.

Answers

Answer:Option D

Explanation:

The continuity of organism on Earth is maintained by the process of reproduction.There are two modes of reproduction. One is sexual reproduction and other is a sexual reproduction.

The asexual reproduction is the process by which identical progeny is produced by single parent. There is no need for two parent.

In case of sexual reproduction the offspring produced is not the exact copy of the parents they show variation. This variation in the offspring provides stability to the organism.

Example of sex linked traits

Answers

male tesosterone can affect facial hair, voice deepness, testicle size, muscle mass, agressiveness, etc

Final answer:

Sex-linked traits are determined by genes located on sex chromosomes. In humans, examples of sex-linked traits include certain conditions such as color blindness, hemophilia, and muscular dystrophy. These traits are more common in males because they receive one X chromosome from their mother, which if contains the recessive X-linked trait, it's expressed in males.

Explanation:

Sex-linked traits are characteristics determined by genes located on the sex chromosomes. These traits tend to express differently in males and females due to the difference in the sex chromosome composition, XY in males and XX in females.

Examples of sex-linked traits can be seen in human genetics, where the alleles for certain conditions such as color blindness, hemophilia, and muscular dystrophy are X-linked. When a female parent who is homozygous for a recessive X-linked trait, she will pass the trait on to 100 percent of her male offspring, as they inherit their father's Y chromosome.

In addition, females who are heterozygous for these diseases are referred to as carriers, may not show any phenotypic effects, but will pass the disease to half of their sons and carrier status to half of their daughters. Thus, recessive X-linked traits tend to appear more frequently in males than females.

Facilitated Diffusion

Facilitated diffusion is the type of diffusion in which the molecules are transported across the channels with the help of transport molecules. Facilitated diffusion is the answer.

What  are  types of facilitated diffusion ?

The  types of facilitated diffusion are carrier protein transport and the ion channel transport proteins.

In  the  process of the facilitated diffusion various molecules are  diffused across plasma membrane with help from  the membrane proteins such as the  channels with carriers. A concentration's  gradient lives for these molecules such that they all  have potential in order to diffuse  in (or out of) cell by just  moving down it.

Facilitated diffusion thus allows polar with the charged molecules such as the  carbohydrates,  amino acids , nucleoside and the  ions for  crossing  the plasma membrane.  Two main  classes of  the proteins that helps facilitated diffusion are generally described as : carrier proteins and  the channel proteins.

In the pea plant, the allele for green pod color (G) dominates the allele for the yellow pod color (g). The Punnet square illustrates a cross for this trait. Which offspring can be described by these genotypes and phenotypes?

Answers

the color of the pea pods will be have a more of a chance to be green due to the fact that there is 75% of the square, because the big G means that it will be that color and if it has (gg) then it will be yellow.

Answer:

a) Homozygous offspring with yellow pod color - gg

b) Homozygous offspring with green pod color - GG

c) Heterozygous offspring with yellow pod color - None

Explanation:

It is given that green pod color (G) is dominant over yellow pod color (g).

Thus, an offspring will have green pod color, when its has heterozygous genotype (Gg) and homozygous dominant genotype (gg). While an offspring will have yellow pod color, only when it has homozygous recessive genotype (gg).

Thus, the offspring with under given phenotypes will have following genotypes -

a) Homozygous offspring with yellow pod color - gg

b) Homozygous offspring with green pod color - GG

c) Heterozygous offspring with yellow pod color - None , a heterogygous offspring will be green in color as green pod color is dominant over yellow pod color.

Answers

In most cases, the dominant form of the trait shows.

Answer:

Option C, The dominant form of the trait shows

Explanation:

In  simple dominance the trait associated with the dominant allele is expressed while the trait associated with the recessive allele is  oppressed. For example –

Let’s assume a flower in which the dominant allele trait is red color and the recessive allele trait is white color. When an offspring of this flower is produced containing one dominant allele and one recessive allele, the color of it would be red only  because only the dominant allele expresses its trait.

The given diagram correspond to the lining of the heart ventricle. The pulmonary circulation of the heart to the lungs occur through the right ventricle. The wall of the ventricles are thicker than atria.

Thus, the correct answer is option (3).

Muscle A is found in the lining of a heart ventricle.

What are the characteristics of heart muscles?The human heart contains cardiac muscle, often known as the myocardium.  Cardiovascular muscle is controlled by an involuntary force.There are three layers that make up the heart: the pericardium, myocardium, and endocardium. Heart muscle is not found in the endocardium. The inner lining of the heart chambers and valves is made up of simple squamous epithelial cells. The epicardium, pericardial space, parietal pericardium, and fibrous pericardium are all components of the pericardium, a fibrous sac that surrounds the heart.The contractility of the heart and consequent pumping motion is caused by the cardiac muscle. The heart muscle must contract with sufficient force and blood flow to meet the body's metabolic needs. The formula for this idea, known as cardiac output, is heart rate x stroke volume.It is based on the heart muscle's ability to contract and how frequently that ability is used. The metabolic demand changes along with the heart's ability to contract.
