How are your coping mechanisms for feeling stressed
related to cellular homeostasis?
When a cell has too much of one thing, homeostasis gets rid of some of it and balances the cell out. Just like when you have too much stress, you find ways (coping mechanisms) to get rid of some of it.

1. The spores on a fern are found:
in the fruit
in the roots
under the leaves
inside the flowers
2. Fern spores usually form during:
spring
winter
summer
fall
3. Why must the plant which grows directly from the fern spore be wet?
in order to produce a seed
so that the egg can be fertilized
so that it can grow
4. Spores are formed in:
ovaries
spore cases
anthers
5. Ferns grow by:
photosynthesis
reproduction
mitosis
6. How do spores help sustain the population of ferns?
Spores do not have any natural predators.
There are million of spores that are made by a single plant to help keep its population.
Spores can hide under rocks for long time before maturing into an adult plant.
Spores can live for a long time without maturing into an adult plant.
7. Choose all the right answers.
When the leaf of a fern touches the ground, it may produce a new plant:
by planting a spore
by vegetative reproduction
by growing roots at the point of contact
by budding from its stem
Answer:
1: C. They are found contained in a casing, called sporangia, and grouped into bunches, called sori, on the underside of the leaves.
2: C. The sporophyte generally releases spores in the summer. Spores must land on a suitable surface, such as a moist protected area to germinate and grow into gametophytes.
3: B: Moisture is needed for germination, growth and fertilization and high humidity for prothalli and young developing ferns after fertilization.
4: B. In ferns, spores are contained within cases called sporangia that are located on the underside of leaves.
5: C. Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis. Because mitosis maintains the number of chromosomes, each cell in the prothallus is haploid.
6: D. the reason why that's the answer is because I read a national geographic paper and it said that spores can live for over a million years without maturing into an adult plant .
7: A and B. Walking fern also has another, asexual, way of reproducing. If the long extended leaf tip touches soil, a new plantlet can form at the tip, produce roots, and become a new plant. The new plant can then grow a long leaf which touches the ground and sprouts another plantlet. In this way the colony gets larger and larger.

Answer:
1. Global warming (as we pass a threshold, it may be irreversible)
2. Reduce the emission of greenhouse gases
Explanation:
Climate change is a general phenomenon associated with the effects of global warming caused by anthropological activities, especially the emission of greenhouse gases (e.g., carbon dioxide, methane, nitrous oxide, etc). It has been shown that global warming is causing an increase in the temperature on the planet at a speed unprecedented since the beginning of the Industrial Revolution. The increase in greenhouse gases in the atmosphere is a direct consequence of human activities, especially from the use of fossil fuels in electricity, heating, transportation, etc. In consequence, it is possible to reduce the impact of global warming by using renewables climate-friendly energy resources, for example, by using solar panels for electricity, solar water for heating and eolic energy for industry (electricity). In this context, it should be taken into account that global warming may be irreversible, and we have the tools to stop it before it is too late.
Which of these is true about energy? A Can be destroyed B Cannot be created C Cannot be transformed D Can be increased in a closed system
Answer:
B
Explanation:
The total amount of energy in the cosmos has never changed and will never change since it cannot be generated or destroyed, hence option B is correct.
What is energy?This does not imply that energy cannot change forms or even move between objects though it does. Energy may transform from more useful forms into less useful forms, but it cannot be generated or destroyed.
Energy gaining or loss is one of two things that can happen to a substance when it loses or gains energy, either its temperature changes or its condition changes.
Therefore, It turns out that some energy gets transformed into a useless form in every real-world energy transfer or transformation (unavailable to do work), hence option B is correct.

PLEASE HELPPP I WILL GIVE BRAINLIEST What effect does starvation or suffocation have on the process of cellular respiration and how would this affect the organism as a whole. include these words: carbon dioxide, glucose, oxygen, water, ATP, reactant, product, food, fermentation, and anaerobic respiration. Please helppp
Answer:
Explanation:
This question seeks to test the knowledge of anaerobic respiration during the process of glycolysis. During intense exercise (or suffocation) the energy/ATP produced (for the short period of about 2 minutes) is as a result of the breakdown of glucose in the absence of oxygen (known as anaerobic glycolysis).
When an individual is fasting or experiencing starvation, the glycogen storage is quickly converted to glucose and then released into the body for cellular breakdown or respiration for the production of energy or ATP. Glycolysis leads to the formation of pyruvate; during suffocation/exercise, the pyruvate (serves as reactant) undergoes fermentation to either produce lactate in humans or ethanol and carbon dioxide in yeast cells (where lactate, ethanol and carbon dioxide serve as products).
Hence, starvation can be said to deplete glycogen storage while suffocation or anaerobic respiration (breathing in the absence of oxygen) causes the cellular breakdown of glucose (glycolysis) to be anaerobic. However, when the glycogen storage starts getting depleted, stored lipids starts getting converted to energy also in the presence of water in body.
It should be noted that the glucose (which is stored as glycogen) is synthesized/obtained from the food we eat.

1. A study was created to test the effects of jazz on people's sleep patterns. The hypothesis of the
experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer
periods of time. For the experiment, 2 groups of people were created. One group was placed in a
quiet room where they went to sleep and they were timed on how long they slept. The other
group was placed in a room where jazz music played softly as they began to sleep and played
throughout the night. As each group awoke, their sleep times were monitored.
What is the dependent variable in this experiment?
Answer:
The correct answer is -
The dependent variable - Sleeping time or amount of both test groups.
Explanation:
In this experiment where the effect of jazz music on the sleeping pattern of people is being tested. For this study, there are two test groups, a control group with a quiet room and an experiment group with slow jazz music during their sleeping and monitored the time when both groups of people sleep.
So, the independent variable is slow jazz music here which is affecting the sleeping amount of time people sleeping, so the dependent variable is the time people sleep

A cell membrane is mostly made of phospholipids and
______
Answer:
Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. Phospholipids are the most abundant type of lipid found in the membrane. Phospholipids are made up of two layers, the outer and inner layers.
So, a cell membrane is mostly made of phospholipids and proteins.
A cell membrane is mostly made of phospholipids and protein and they have their specific functions.
Cell membrane comprises of phosholipid bilayer which lipid and cholesterol and is useful in the selective passage of molecules in and out of the cell of the organism.

The nucleus is surrounded by a membrane. This membrane has pores that enable the nucleus to carry out one of its functions. What do these pores allow to happen?
A) nutrients that are stored in the nucleus to enter the cytoplasm
B) proteins that are made in the nucleus to pass into the cytoplasm
C) waste substances to enter the nucleus
D) genetic information to pass from the nucleus to the cytoplasm
Answer:
D
Explanation:
The nucleus contains the genetic information of the cell. When the cell needs instruction to make protiens, Rna carries those instructions out of the cell because DNA is too large to fit through the pores. Proteins are made in the ribosomes.
