Differentiate between sub-cellular and acellular particles with examples

Answers

Answer:

Explanation:

Sub-cellular particles are particles smaller than the living cell and are found suspended in the cytosol (of a cell) like the nucleus, golgi complex and the mitochondria.

While acellular particles/organisms are particles that do not have a cell like the virsues, viroids and prions. They are not alive/inactive outside a living environment but become active immediately they are inside a living environment (like a cell).

Sub-cellular particles are structures that are found within a cell. These structures perform specific functions and are essential for the cell to carry out its biological processes.

Examples of sub-cellular particles include organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These structures are composed of both proteins and lipids and are enclosed by a membrane.

Acellular particles, on the other hand, are particles that do not possess a cellular structure and are not alive. These particles are much smaller than cells and are unable to carry out any metabolic processes.

Examples of acellular particles include viruses, prions, and viroids. These particles are composed of either DNA or RNA and can replicate themselves only within a host cell. They do not have their own metabolism and rely on the host cell for replication and survival.

Only ------ percent of the food eaten is turned into its own body. ​

Answers

Answer:

10%

Explanation:

there is a the rule that only 10% of the energy is transferred from one trophic level to the other.

this means that only 10% of the food an organism eats  is passed onto the next organism. eg only 10% of the energy in a plant is transferred to a rabbit that eats the plant. After that if  a wolf eats the rabbit only 10% of the energy of food will pass on to the wolf.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything

Answers

The question is incomplete,below is the complete question.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"

You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."

QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?

Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.

Answer:

A Detritivore

Explanation:

A Detritivore is a heterotrophic organism that feeds on dead plant and animal materials. They could also feed through coprophagy which is nutrition obtained by feeding on feces. Worms that dwell on the soil, insects, and mollusks are examples of detritivores. Detritivores can also be found residing in aquatic environments. Crabs and Lobsters are examples of these organisms.

Detritivores have no teeth. So, they tend to suck in their food, and this food, through peristaltic actions, moves directly into the digestive tract where it is acted upon by digestive enzymes. From the observations, I made about the organism at the mudflat at the ocean, I can conclude that it is a detritivore.

Algae in the genus Caulerpa typically grow to a length of over half a meter and have structures similar to stems,leaves,and roots.Reproduction occurs when adults produce sperm and eggs that fuse to form offspring.Each adult Caulerpa consists of just a single cell,however.Which of the following statements is true?
A) Caulerpa violate the pattern component of the cell theory that all organisms consist of cells.
B) Caulerpa violate the process component of the cell theory that all cells come from preexisting cells.
C) Caulerpa violate both the pattern and process components of the cell theory.
D) The existence of Caulerpa is consistent with the cell theory.

Answers

Answer:

D) The existence of Caulerpa is consistent with the cell theory.

Explanation:

This question describes species of algae in the genus, Caulerpa, which is a unicellular organism that possesses structures similar to leaves, stems and roots in plants. It also grows to a length of about 0.5metres. it reproduces sexually by fertilization of gametes (sperm and egg).

According to all these described characteristics of Caulerpa, it's existence is in conformity or accordance with the unified cell theory, which was proposed by three scientists namely: Matthias Scleiden, Theodor Schwann, and Rudolf Virchow in the 1830's. The three components of the cell theory states that:

1. Cell is the fundamental and basic unit of life existence.

2. All living organisms are composed of one (unicellular) or more cells (multicellular).

3. All cells come from already preexisting cells.

Hence, based on the components of the cell theory and the life pattern of Caulerpa i.e. Caulerpa is made up of one cell, it is made from the fusion of preexisting parental cells etc. It is consistent with the cell theory.

Consider the following chromosomes and if they are affected by hemophilia.

X = unaffected X chromosome, x = X chromosome affected by hemophilia, and Y = Y chromosome.

If an Xx female and XY male have children, what fraction of their offspring will have an affected chromosome, and what fraction is likely to be affected by hemophilia?

(1 point)
A. 1/4 and 1/2
B. 1/2 and 1/4
C. 1/2 and 1/3
D. 1/4 and 1/4

I've been stuck on this question for a while, may someone please assist?

Answers

Answer:

B. 1/2 and 1/4

Explanation:

Hemophilia is a rare disease that has to do with the inability for blood to clot. It is inherited on the X chromosome, hence, it is said to be X-linked. It is usually passed from mother to son. According to this question;

X - unaffected X chromosome

x = X chromosome affected by hemophilia

Y = Y chromosome

Therefore, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:

Xx- X and x gametes

XY- X and Y gametes

Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY will be possibly produced.

XX (1) - unaffected female

Xx (1) - unaffected but carrier female

XY (1) - unaffected male

xY (1) - affected male (have hemophilia)

Based on the questions;

- 2 out of the possible 4 children will have the affected chromosomes i.e. both xY son and Xx daughter have the affected (x) chromosome. Hence, the fraction is 1/2

- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

ISCHEMIC HEART DISEASE.

Explanation: To answer the question effectively, let us look at the options given,what they are and how they affect the heart.

Endothelial cells play a crucial role in the regulating vascular tone,They do so by secreting variable amounts of constricting and relaxing factors inorder to control tissue perfusion.

Hypertension on the other hand occurs as a result of factors that varies distinctively and not all related to vascular tone.

Dysrhythmias on it's own will affect the function and conduction of heart chambers but not necessarily vascular tones.

other. Describe an action that would best improve the reliability of their results?

Answers

Answer:

To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.

Second, the experiment should be carried out under greenhouse conditions.

The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.

By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.

Jenna published the results of her latest experiment for the public to see.Elena keeps complete records of all her experiment results.Neal shared the results of his field study even though they didn't support his hypothesis.

Irresponsible behavior

Malcolm altered an experiment to be able to reach his desired conclusion

Responsible behaviors are those that support responsible scientific practices and do not jeopardize the objective nature of research. Every data during experiments must be well kept and after thorough analysis, results must be published fro the public to see irrespective of whether it agrees or disagrees with the original hypothesis.

Altering an experiment in order to achieve the desired result is grossly irresponsible, as this eliminates the objectivity that should be the main goal of every experiment. Bias must be eliminated from every scientific experiment.

Natural selection states that complex organisms evolved through random mutations alone. True or False?

Answers

Answer:

False.

Explanation:

This statement is false because organisms don't evolve - populations do. New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population. However, because mutation rates are low relative to population growth in most species, mutation alone doesn't have much of an effect on evolution.
