As you open the door you realize you cannot breathe. You quickly shut the door, realizing you are in the _____.
1) Archaean eon
2) Cambrian period
3) Cenozoic era
4) Mesozoic era

Answers

Answer 1

Answer: Option 1 is the correct answer

Archaean eon

Explanation:

You are in the Archean Eon era because the it was early in the Archean that life first appeared on Earth. The most two earlier of the formal divisions of Precambrian time (about 4.6 billion to 541 million years ago) and the period when life first formed on Earth It began about 4 billion years ago with the formation of Earth’s crust and enlongated to the begining of the Proterozoic Eon 2.5 billion years ago; the latter is the second formal division of Precambrian time.

In the Archean eon there are unsual landscapes no rocks are preserved from this stage. The earliest terrestrial materials are not rocks but minerals.

Throughout the Archean, oceanic and island arc crust was produced semi-half way.

You cannot breathe because there was no oxygen on the Earth. Oxygen was only present in compounds such as water and chemical reactions change to carbon containing molecules that form simple living cells that does not require oxygen.

Endometriosis occurs when endometrial tissue, which normally grows inside the uterus, grows outside the uterus. Based on the model, what effects would you expect these growths to have on the female reproductive system and on fertility?

Answers

Answer:

Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.

In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.

Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.

Explanation:

Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.

The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.

Answer:

abnormal tissue growing on the ovaries might affect ovulation, making it harder or impossible for women to get pregnant. The extra tissue may cause pain, since the tissue is growing in places it is not meant to be growing

What happens when volcanoes release greenhouse gases into the atmosphere?

Answers

Answer:

a. the climate gets warmer...

Explanation:

When volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.

What do you mean by the Greenhouse effect?

The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere.

Greenhouse gases like carbon dioxide, Methane, and Nitrous oxide allow the solar radiations to enter but prevent the escape of heat radiations of longer wavelength.

Due to this, the gradual and continuous increase in the average temperature of the earth's surface occurs, a phenomenon known as global warming.

Therefore, when volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.

Which characteristic does a virus have in common with a eukaryotic cell?

Answers

Viruses are not cells; they are a strand of genetic material within a protective protein coat called a capsid. They infect a wide variety of organisms, including both eukaryotes and prokaryotes. Once inside the cell, they use the cell's ATP, ribosomes, enzymes, and other cellular parts to replicate.

The characteristics that a virus cell possess with eukaryotic cell is that they both possess a genetic material.

What is an eukaryotic cell?

An eukaryotic cell is a cell that has a genetic material bound by membrane-bound nucleus.

A virus cell, on the other hand, is a cell that is incapable of replicating itself without a living host.

However, one similarity between the eukaryotic cell and viral cell is that they both possess a genetic material that stores their genetic information.

B. could destroy the hypothasis of continental drift

C. could not provide a mechanism for moving continents

D. could explain how the seafloor was being destroyed

Answers

Answer:

C. could not provide a mechanism for moving continents

Explanation:

Magnetic reversals have the habit of causing geological displacements, since they are directly linked to the movements and distribution of tectonic plates on the planet, which are responsible for the movements of the continents. In this case,

if the discovery of magnetic reversals recorded on the ocean floor were not carried out, it would be impossible to establish its relationship with the movement of the tectonic plates, making it impossible to provide a mechanism for moving continents.

Shivering and vasoconstriction would be signaled to cause a: A. increase in pH. B. decrease in temperature. C. decrease in pH. D. increase in temperature.

Answers

Answer:D

Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body

Vasoconstriction is the narrowing of the blood vessels that hinders blood flow. Vasoconstriction and shivering will lead to an increase in the temperature through thermoregulation. Thus, option d is correct.

What is thermoregulation?

Thermoregulation is the maintenance and balancing of the temperature and heat in the body. They are regulated by many factors including shivering and vasoconstriction.

During the vasoconstriction, the blood vessels close to the skin surface close and the body shivers as a result of cold or decreased temperature. This signals the body to increase the temperature so that shivering can be stopped.

Therefore, vasoconstriction and shivering signal the body to increase the temperature.

Answers

Answer:

The correct answer is option : d. evolution.

Explanation:

Change in the heritable traits or characteristics of population of a organism over time by the adaption or changes in genes of such population over successive generation is known as the evolution.

These changes that cause the evolution of the biological population is caused by the process of adaption through natural selection that is the ability of the passing beneficial genes from parent to offspring.

Thus, the correct answer is option D. evolution.

Drag each label to the correct location. Classify the interactions as being direct or indirect competition. Two eagles fight over a salmon carcass.

Answers

Answer:

Two eagles fight over a salmon carcass- DIRECT

All the gray foxes in a habitat prey primarily on penguins- INDIRECT

Two colonies of black ants clash over a wasp- DIRECT

Gray squirrels in an area rely on nuts for food- INDIRECT

Explanation:

Living organisms of same or different species tend to interact with one another in their natural habitat. One of those interactions is competition, which occurs when living organisms share the same limited resources or occupy the same niche in their habitat.

However, competitive interaction between organisms can either be direct or indirect. Direct interaction is that which involves a physical interaction between the organisms i.e. a confrontation. A struggling for the limited resource is evident. For example, two eagles fighting over a salmon carcass and two colonies of black ants clashing over a wasp shows the form of physical confrontation for the limited resource between the organisms involved. Hence, they are examples of direct competition.

On the other hand, indirect competition involves the competition for a limited resource without a physical confrontation or struggle. Organisms make use of the limited resource until it becomes unavailable to competitors. For example, gray foxes in a habitat that prey primarily on penguins and gray squirrels in an area relying on nuts for food shows a competition for a scarce resource without any physical interaction between them. Hence, they are examples of indirect competition.
