Answer: 5
Explanation:
The number of mass extinctions that have occurred on Earth in the last 4.6 billion years is five. Thus, the correct option for this question is C.
What do you mean by Mass extinction?Mass extinction may be defined as a type of event in which a large number of species undergo extinction within a relatively short period of geological time, due to some factors such as catastrophic global consequences, volcanic activity, asteroid explosion, etc.
Mass extinction is also known as mass diversity loss. The first mass extinction occurred in the Ordovician period, the second occurred in the Devonian period, the third occurred in the Permian period, the fourth occurred in the Triassic period, and the fifth occurred in the Cretaceous period.
The third mass extinction is the biggest mass extinction in which 90% of life forms were lost. In which 90-96% of species are extinct.

How do molecules move into and out of most animal cells?
Answers
Answer:
The simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. Passive diffusion is thus a nonselective process by which any molecule able to dissolve in the phospholipid bilayer is able to cross the plasma membrane and equilibrate between the inside and outside of the cell.

D. They would not be able to take water up into their roots.What would happen to plants if bacteria were completely removed from soil?The removal of bacteria from the soil could have a drastic effect on the growth and survival chances of plants.
Bacteria serve a vital purpose in the soil, as they decompose organic matter into nutrients that plants can be easily absorbend through their roots.
Furthermore, some kinds of bacteria even establish a symbiotic relationship with them, participating in an exchange of nutrients between organism and plant. If all bacteria were to be absent from the soil however, vegetation would not have access to these essential nourishments nor be able to take in water adequately, both of which are requisite for its survival. Accordingly, option D is the right solution.

Answers
In the chamber, we turn the carbon dioxide valve all the way up. in chamber b we only provide half as much carbon dioxide as the first chamber plants.
Carbon dioxide is an odorless, colorless fuel. it's miles a waste product that your body makes whilst it makes use of food for energy. Your blood consists of carbon dioxide in your lungs. when you exhale, you breathe out carbon dioxide. Having too much or too little carbon dioxide in your blood can be a signal of a health problem.
Natural resources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that cause carbon dioxide emissions come primarily from energy production, along with burning coal, oil, or natural fuel.
Hypercapnia, or hypercarbia, is when you have an excessive amount of carbon dioxide (CO2) in your bloodstream. It generally occurs because of hypoventilation or no longer being able to breathe properly and get oxygen into your lungs.

Tree pollen is a common hay fever trigger. It’s the first pollen to be released during hay fever season, and levels are typically highest from late March to mid-May.
Around 95% of people’s hay fever is triggered by grass pollen, which tends to be highest between mid-May and July. In fact, there’s strong evidence that when grass pollen levels are high, people with asthma are more likely to need hospital treatment.
Hay fever can also be triggered by weed pollen, which is highest from the end of June until September.
Know your pollen triggers
You can be allergic to more than one kind of pollen across the year. Different pollens are released at different times, but our changeable weather makes it hard to predict exactly when. If you have hay fever symptoms all year round you might have non-allergic rhinitis.
If you regularly get hay fever and take antihistamines, start taking them up to four weeks before you normally get symptoms. Starting them early means that when pollen starts being released, the medication has already built up in your bloodstream so you may be less likely to react.
If you usually use a steroid nasal spray, it can take up to two weeks to start working, so again, start using it before your personal pollen trigger is released.

Which organelle plays a role in intracellular digestion? lysosome chloroplast ribosome golgi apparatus plasmodesma
Answers
Lysosome organelle plays a role in intracellular digestion.
What is intracellular digestion?To function, all living things need energy. Cells must not only take molecules from their surroundings but also disassemble them in order to get energy from their external environment. Internal digestion is the term for this process.
Intracellular digestion refers to the process of food digestion that occurs directly inside the cells. Species with only one cell, such as amoebas, experience it.
When food is digested intracellularly, food components are broken down into smaller molecules inside of the cell's food vacuoles. When food is broken down into small molecules through extracellular digestion, it happens outside of the cell, either on decomposing organic matter or in the alimentary canal lumen.

Passive transport refers to the movement of molecules across a cell membrane without the need for energy input from the cell, while ATP is a molecule that provides energy for cellular processes. The driving forces for passive transport include concentration differences, electrical gradients, and osmotic pressure.
ATP (adenosine triphosphate) is a molecule that provides energy for cellular processes in living organisms.

natural selection is the phenomenon in which certain phenotypes have than other phenotypes. multiple choice question. greater reproductive success more success in gathering nutrients perfect adaptations to the environment longer lifetimes
Answers
The correct answer to your multiple-choice question is "greater reproductive success".
Natural selection is the process by which organisms with advantageous traits or characteristics that allow them to survive and reproduce in their environment have a higher likelihood of passing those traits on to their offspring. This leads to an increase in the frequency of those traits within a population over time. Therefore, individuals with greater reproductive success have a higher chance of passing on their advantageous traits to the next generation, leading to the evolution of a population. Reproductive success is a crucial component of natural selection as it determines which traits are passed on and which ones are not. To summarize, natural selection favors traits that increase an organism's chances of reproductive success and passing on its genes to future generations.
