•oxytocin
•follicle-stimulating hormone
•estrogen
•gonadotropin-releasing hormone

Answers

Answer: Stimulates the contraction of the uterus during childbirth - OXYTOCIN

Stimulates sperm production and growth of ovarian follicles - FOLLICLE STIMULATING HORMONE

Initiates the Secretion of leutinizing hormone and follicle stimulating hormone - GONADOTROPIN RELEASING HORMONE

Initiates the development of secondary sex characteristics in females - ESTROGEN

Initiates the development of secondary sex characteristics in males - TESTOSTERONE

Initiates cell production of testosterone and estradiol by cells in the gonads - LUTEINIZING HORMONE.

The correct match for hormone and their functions are- 1- Oxytocin, 2- follicle-stimulating hormone, 3- a gonadotropin-releasing hormone, 4- estrogen, 5- testosterone, and 6- luteinizing hormone.

Oxytocin is a naturally occurring hormone that plays a vital role in the reproductive system of both men and women, including labor, delivery, and breastfeeding, as well as in human behavior.

FSH is produced by the pituitary, which is a small gland just below the brain. The pituitary plays a vital role in the development and regulation of sexual function.

Gonadotropin-releasing hormone stimulates the brain’s pituitary gland to produce and release the hormones LH and FSH.

Estrogen is a family of hormones that play a vital role in the reproductive and sexual development of women.

Testosterone is a male sex hormone. It is responsible for spermatogenesis and fertility in males.

Luteinizing hormones (LH) are hormones in the body that stimulate the reproductive system. Luteinizing hormone stimulates ovulation and stimulates the production of the hormones needed for pregnancy

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.

Scientists are able to reproduce certain plants and animals by cloning them in laboratories. The diagram shows the steps of cloning using tissue cultures. Do you think cloning is a form of asexual reproduction? Explain your answer using evidence from the diagram

Answers

Answer:

Yes.

Explanation:

Yes, cloning is a form of asexual reproduction because there is no fusion of sperm and eggs takes place. the animal which is formed from this process is identical of that organism because it is produced from the tissue of that single animal. in 1996, first mammal is produced from cloning was sheep named dolly at the Roslin Institute in Scotland. In cloning, the egg is taken from female organism and remove the nucleus from the egg then the desired organism cell is taken and fuse with the nucleus with the help of electricity. Then implant this embryo in the body of first organism from where egg is taken and after that the embryo turns into a baby, this process is called cloning.

Answer:

Yes, cloning is a form of asexual reproduction. The diagram shows that new plants form from a single parent plant, which means that the offspring are genetically identical to the parent.

The immune response of a host against an invading bacterium is often triggered by surface components on the bacterium that are recognized as "non-self" or "foreign" by the host. These non-self components, often protein or polysaccharide in nature, are referred to as antigens. The host responds to these antigens by making antibodies that will react with invading bacteria and mark them or tag them for destruction by phagocytes.

Indicate the bacterial structures that are likely to be antigens, to which host antibodies bind, marking the invader for phagocytosis

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.

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.

Answers

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.

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.

When objects of two different temperature are in contact, what happens?

Answers

Answer:

The answer is C.

Explanation:

This is because the objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.

Energy is transferred from a warmer to a cooler object through the phenomenon of heat. For instance, a large pan of lukewarm water will gain heat from a lit match (a higher temperature object) (lower temperature object). Thus, option C is correct.

What change in temperature when object are in contact?

It feels warmer in your hands to hold a hot cup. The heat is moving from one object to another, which is what you are feeling. Your hands receive the hot chocolate's thermal energy.

Heat is exchanged when two objects are at different temperatures. Up until the two items are at the same temperature, the cooler object warms up. Always, heat energy moves from a hot object to a cooler one.

The colder end will get energy from the hot end as it passes through the rod. The temperature will eventually equalize across the entire rod. Wearing gloves is crucial when working with hot metal, for this reason.

Therefore, The warmer object transfer heat energy to the cooler object.
