While the ovum is on its way to the uterus, a successful mating results in the presence of sperm cells in the fallopian tube. One of these sperm cells fertilizes the ovum. How does this event affect the corpus luteum?

Answers

Answer 1
If the sperm cell fertilises the ovum, and implantation does not occur, then the corpus luteum degenerates and it turns into corpus albicans, stopping progesterone secretion. If fertilisation occurs and implantation also, the syncytiotrophoblast, the "root part" of the blastocyst (one of the early structures originated from the zygote), produces a hormone that is called human chorionic gonadotropin (hCG). The hCG is what makes the corpus luteum keep secreting progesterone and maintain itself. The progesterone will then help keep the endometrium and, therefore, allow the development of the embryo to happen.

Answers

Answer:

The correct answer is option A More cropland

Explanation:

As the human population will increase, their demand for resources will also increase specifically for the three essentials namely  air, water and food. In order to cater the need of increased food demand, more food is needed to be produced and thus more land is required. Apart from agricultural produce, even dairy farms, aquaculture or any other  method of production of non vegetarian/other food sources,  also require large amount of pasture land or crop land.

The two biomes that are the most similar with regard to rainfall is Tundra and Desert

For better understanding let's explain what Tundra and Desert biomes are

Tundra is simply known as a type of biome that is characterized by plains having no tress. They are the coldest of all the biomes as well as they are occur in the arctic and Antarctica. Lichens, mosses, sedges, and dwarfed shrubs etc are found in this biome.

Desert can be hot and cold. A hot desert is a biome characterized by low moisture levels, daily and seasonal temperatures fluctuate due to the fact they receive little rainfall that it supports only little and widely spaced vegetation or no vegetation at all.

Cold Deserts sometimes has a lower freezing for some periods of time. e.g. Great Basin Desert

The two biome receive little or no rainfall that more of the reason they are similar

From the above we can therefore say that the answer the two biomes that are the most similar with regard to rainfall is Tundra and Desert is correct

What is the main difference between a reflex and a habit?

Answers

A reflex is a built in operation that performs without orders from your mind.
A habit is something you as a person forms and we can train our minds to stop the habit.

The main difference between a habit and a reflex is that a habit is based on a reflex, but it is completely separated from the original stimulus.

What is a Reflex and habit?

Reflexes (reflex action) are relatively simple motor responses organized by the brainstem and enables the body to adjust rapidly to sudden changes in the external environment.

A reflex, or reflex action, is an involuntary, unplanned action. It is an almost instantaneous movement in response to a stimulus. A reflex action takes place by neural pathways called reflex arcs which can act on an impulse before the impulse even reaches the brain.

A habit is a behavior that is repeated regularly and occurs subconsciously. The habit is defined from the standpoint of psychology, as a more or less fixed way of thinking, willing, or feeling acquired through previous repetition of a mental experience.

Which populations would benefit the most from the presence of decomposers?

Answers

I'm guessing there was answer choices to this problem? regardless I think I know the answer to it. Plant populations would benefit the most of the presence of decomposers due to the fact that decomposers release nutrients into the soil when they break down things.

Answer:

Producers (plants) would benefit most from the presence of decomposers.

Explanation:

The act of recycling practiced by decomposing beings plays an important role in the ecological balance of the planet, because in addition to putting an end to the organic remains of dead beings, they produce nutrients. These nutrients are essential for the continuity of life within ecosystems. Plants, for example, are extremely dependent on this process as they need to absorb nutrients in the soil to grow. As the plants represent the producer population, it can be said that the producers will benefit most from the presence of decomposers.

Which foods, mentioned in the text, help digestion?

Answers

Final answer:

Although no specific foods are mentioned, the text implies that foods rich in proteins, carbohydrates, and lipids are essential for digestion, beginning in the mouth and finishing in the small intestines.

Explanation:

The question doesn't directly specify any foods from the provided text that aid in digestion. However, the student can infer from the text on digestion that foods rich in proteins, carbohydrates, and lipids are essential as they begin chemical digestion starting in the mouth that is then completed in the small intestines. For instance, the process of lipid digestion begins in the intestine, facilitated by bile and the enzyme pancreatic lipase. Proteins and carbohydrates, on the other hand, start their initial digestion process in the stomach and are subsequently broken down in the small intestine with the aid of intestinal and pancreatic juices.

Why do different people make different decisions about how a technology should be used?

Answers

people are greedy, and use technology to their advantage in the best way to obtain profits, or to boost their knowledge.
Final answer:

People make different decisions on technology use based on personal values, experiences, and societal norms. Access to technology can lead to greater opportunities, though experiences may differ, and the rapid pace of technological advancement poses challenges for societal adaptation. Regulations and societal norms vary globally, affecting how technology is used and controlled.

Explanation:

Different people make different decisions about how a technology should be used due to a variety of factors including their personal values, experiences, knowledge level, and the cultural and societal norms they adhere to. For example, one person might see a smartphone as a tool for enhancing productivity and connecting with others, while another might view it as a distraction or a risk to privacy. Additionally, the rapid pace at which technology evolves often outstrips the ability of societies to evaluate and integrate new tools in a considered way, resulting in disparate opinions and uses.

Indeed, people bring their own perspectives to the debate on whether access to technology correlates with greater opportunities. In my own life, I know individuals who have leveraged technology to build successful careers and enhance their education, supporting the idea that technology use often opens doors. Conversely, others may challenge this notion, citing technological divides or negative impacts of technology on certain aspects of life, like communication and well-being.

An educational leader facing contradictory research on technology's impact might approach the situation by integrating diverse findings, remaining open to varying evidence, and seeking a balanced understanding that can inform a nuanced approach to technology integration in educational settings.

The use of technology in society also raises complex questions about its regulation. In democratic societies like the United States, these issues are often resolved through the court system, reflecting a balance between personal freedoms and societal protections. However, this process and the outcomes can vary significantly around the world, influenced by differing governmental structures and cultural values.

Answers

Answer:

The answer is sensory neurons

Explanation:

i just got it right on my test

Final answer:

Salma's retinas receive visual information from the impressionist painting and transmit it to her brain. Retinas are crucial for visual perception, which is influenced by cultural background and emotional responses.

Explanation:

As Salma views a famous impressionist painting that is hung on a wall, her retinas receive visual information about the art and carry this information to her brain. The retina is a part of the eye that contains cells sensitive to light, which convert light into electrical signals that are transmitted to the brain through the optic nerve. This biological process is at the core of visual perception, allowing Salma to experience the painting's colors, shapes, and composition.

The personal perception of art is highly subjective and varies among individuals. Our cultural background and individual experiences influence how we 'read' a piece of art. This includes not only where we begin to look at an image but also the types of information we perceive and process.

In addition to sight and cognitive processes, our emotional responses also contribute to how we appreciate art. Emotions, similar to physiological reactions such as a quickened heartbeat or widened eyes, can potentially guide or reinforce our artistic judgments.

Which are specific to just prokaryotes, or just plants, or just animals? drag the appropriate items to their respective bins. helpreset vacuoleslack a cell walllysosomesmagnetite-containing structureschloroplaststhe nucleoidphotosynthetic membranesflagella and fimbriae?

Answers

Answer:

Prokaryotes: Prokaryote are simple, single-celled organism that lacks a well defined nucleus and membrane-bound organelles.

Photosynthetic membranes: Some of the prokaryotes have photosynthetic membrane to capture sunlight energy which facilitates the process of photosynthesis.

Flagella and fimbriae: Flagella and fimbriae are simple, fibrous structures which facilitates the movement in simple prokaryotes.

The nucleoid: The nucleoid is the organelle in the prokaryotes in which the genome of the prokaryotic organism is stored.

Magnetite-containing structures: These are organelles specific to prokaryotes.

Just plants: Plants are autotrophic organisms that are capable of making their own food by the process of photosynthesis. All plants belongs to the kingdom Plantae.

Vacuoles: Vacuoles are organelles not just but mainly found in plants. They functions as discharge of cellular or metabolic waste from plants.

Chloroplasts: It is an organelle that is found in plants that exhibit chlorophyll  pigment, which traps the sunlight necessary for photosynthesis.

Just animal: Animals are hetrotrophic organisms that derive their food from other organisms such as plants and animals. They belong to the kingdom Animalia.

Lysosomes: These are specialized cell organelles, which are also called as suicidal bags. Found mainly in animals. These organelles traps cellular waste and facilitate it's discharge from the body.

Lack a cell wall: Animals lack a cell wall, which is found mainly in plants.



The cell organelles that are only present in prokaryotes are flagella and fimbriae. The cell organelles that are only present in animals are lysosomes and cytoskeleton. The cell organelles that are only present in plants are photosynthetic organelles, cell wall, and vacuoles.

Further explanation:

Kingdom Animalia contains all the animals. These are multicellular organisms that acquire food from the phototrophic plants either directly or indirectly (heterotrophs). The cell wall is absent in a typical animal cell, but structures like cytoskeleton that gives rigidity to the cell and lysosomes that are known as suicidal bags are present.

A plant is an autotrophic organism that is the primary producer. The stem, roots, leaves and sometimes fruits are the typical parts of a plant. A typical plant cell contains photosynthetic organelles that help in the preparation of the food, a cell wall that gives rigidity, and vacuoles that contain cell sap.

Prokaryotes are the simplest cells on the earth. A typical prokaryote is a unicellular cell containing mitochondria and some organelles.

Bacteria and archaea are the two types of prokaryotes. The bacteria contain the peptidoglycan layer which is absent in the archaea. The archaea contain ether-linked lipids while the bacteria contain ester-linked lipids. Flagella are structures that is used by all the prokaryotes for movement. The fimbriae in the prokaryotes help in the attachment of the bacterial cell to the animal cell or even the inanimate objects.

Explain how the two main theories of color perception, initially appearing to contradict each other, are, in fact, complementary perspectives.

Answers

Final answer:

The trichromatic theory and the opponent-process theory are the two main theories of color perception. They seem contradictory at first glance, but in fact, they complement each other and explain different stages of color perception.

Explanation:

The two main theories of color perception, which initially appear contradictory, are, in fact, complementary when examined closely. These are the trichromatic theory and the opponent-process theory.

The trichromatic theory explains that our color perception is a product of the relative outputs of the three types of cone receptors in our eyes which are sensitive to different parts of the light spectrum, approximating red, green, and blue light. When all three are equally stimulated, we perceive white light.

On the other hand, the opponent-process theory suggests that we perceive colors in contrasting pairs - black-white, red-green, and yellow-blue. This theory explains the phenomenon of afterimages and color constancy, where the eye and brain compensate for changes in lighting conditions to maintain a stable color perception.

Seemingly contradictory, these theories are, however, quite complementary. Trichromatic theory describes color perception at the level of the photoreceptors in the eye, while the opponent-process theory explains how signals from these receptors are processed in the brain.
