What would happen if the mitochondria were missing from a cell?

Answers

Answer:

We'd be in big trouble...

Explanation:

The mitochondria is the powerhouse of the cell, without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.

The absence of mitochondria would have a profound effect on cellular function, including the cell's ability to produce energy, regulate ROS levels, and control important signaling and metabolic pathways. Such a cell would likely be unable to survive for very long.

What is the effect of mitochondrial removal?

Without mitochondria, the cell would not be able to generate ATP through aerobic respiration, which takes place in the mitochondria. Instead, the cell would have to rely on other, less efficient metabolic pathways to produce energy. Mitochondria are also important for regulating the levels of reactive oxygen species (ROS) in the cell. Without mitochondria, the levels of ROS would likely increase, leading to oxidative damage to the cell's proteins, lipids, and DNA. Mitochondria play important roles in cell signaling pathways, including those involved in apoptosis (programmed cell death) and calcium signaling. Without mitochondria, these pathways would likely be altered, which could have profound effects on cellular function and survival.

Hence, such a cell would likely be unable to survive for very long.

What information is not given in this equation.

A)It does not show if the reaction is reversible or not reversible.

B)It does not show the reactants needed for the reaction.

C)It does not show that photosynthesis consists of many separate steps.

D)It does not show the number of molecules required to produce glucose.

Answers

Answer:

C

Explanation:

C appears to be the best answer but I think a better answer would be that it didn't include another product which is oxygen. So unless it is late and my brain is not function, I would say that should be the answer. But otherwise, since it is not there, C is the best one I think.

The chemical reaction equation of photosynthesis is shown here:

6CO2 + 6H2O → C6H12O6, C)It does not show that photosynthesis consists of many separate steps. Thus option "C" is correct.

What is photosynthesis?

The chemical reaction of photosynthesis is given as follows;

6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)

Therefore, six molecules of gaseous carbon dioxide (CO₂) combine with six molecules of liquid water (H₂O) in the presence of energy from Sunlight  to produce  one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)

The 6O₂ is the gaseous oxygen produced as a byproduct of photosynthesis

Explanation:

The property of water in "Large, circular lily pads are able to float on the water's surface" is cohesion.

What is cohesion?

Cohesion refers to the attraction of one water to another. This force will cause the water in the lake to develop surface tension. The large and thin leaf of the water lily gives it a low force per area.

The leaf will float above the water if the force acting on the surface is not greater than surface tension. The ability of water spiders to walk on the surface tension of the water.

The leaves of lotus float on the water because the bottom of the leaves have edges and thick ribs that capture air between them, which helps them to float on the water.

Answer: If a land fertilizer were used on the algae it would severely damage the plant and suffocate it.

Explanation: Fertilizers are used by homeowners to maintain and improve landscape beauty and quality. In recent years, increased use of home lawn and garden fertilizers has caused concern about pollution of lakes and groundwater. Proper fertilizer application can enhance plant growth without polluting the environment. Yet, misuse of fertilizer may not only harm the environment—especially ground and surface water—but may in fact result in injury to landscape plants as well. The nutrient phosphorus harms clear, free water by creating algal blooms. This process, known as eutrophication, turns the water green, clouds the water, causes odor problems, and depletes the oxygen for fish and other species, effectively suffocating them.

Answer:

Well knowing that most fertilizers help algae grow, my prediction is that the algae expectantly grow at a high rate. The rain would also help the growth and might even get the algae in the water systems.

What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?

Answers

Answer:

Please mark as brainliest!!!

Explanation:

Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.

It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.

Which pair of properties apply to both mechanical and electromagnetic waves?

B.
Both waves are longitudinal and refract

C.
Both waves are transverse and carry matter from one place to another

D.
Both waves carry energy and do not need a medium to travel through

Answers

Answer:

A. Both waves carry energy and refract

Explanation:

There are two major types of waves viz; mechanical waves and electromagnetic eaves. Mechanical waves such as sound waves are waves that require a medium or matter to pass/travel through while electromagnetic waves like light waves do not strictly require a medium to travel i.e through vacuum.

Electromagnetic waves are transverse waves i.e their particles move perpendicularly to the direction of the wave while mechanical waves can either be transverse or longitudinal. All waves carry energy from one medium to another and are capable of refraction i.e. change of direction.

Therefore, both mechanical and electromagnetic waves carry energy and refract.

If an H is for tall trait which is dominant and h is the recessive trait for short,
which of the following crosses will result in 1:1 tall:short progeny (offspring).

A) HH Xhh
B) hh X hh
C) Hh X hh
D) Hh X Hh

Answers

Answer:

The cross that guarantees a height trait ratio in the offspring of 1 : 1 high/low is Hh X hh (option C).

Explanation:

For a characteristic such as size, where tall (H) is the dominant trait and short (h) is the recessive, the crossing of a tall heterozygous (Hh) individual with a short one will have a probability that half of the offspring will be tall and the other half short.

This can be demonstrated with a Punnett square:

Cross Hh X hh

Alleles      H      h

h              Hh    hh

h              Hh    hh

Based on this result, half of the offspring will be tall, with genotype Hh, and the other half short, with genotype hh, which corresponds to a tall : short ratio of 1 : 1.

In the other options is not possible to obtain this result:

A) HH Xhh  = 100% Hh.

B) hh X hh  =  100% hh.

D) Hh X Hh = 50% Hh, 25% HH and 25% hh.

Dr. Kettlewelll predicted that clean forests would have _____________ colored moths, and polluted forests would have _________ colored moths.

Answers

Answer:

Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.

Dr. Kettlewall predicted that clean forests would have light-colored moths and polluted forests would have dark-colored moths. This is an example of natural selection.

What is natural selection?

Natural selection is a phenomenon in which the fittest individual is chosen by nature. The animal can live and reproduce in that particular environment. An example is the peppered moth population.

The light-colored moths were found on the light-coloured bark, but their population started to decline after the pollution. In the polluted environment, they were easily chosen by predators. So only dark moths survived because they blended in with the polluted environment.

Following the end of the pollution, light colored moth increased again. Predators had a difficult time identifying the light moth because it blended in with the unpolluted environment. Hence, their population increases in unpolluted areas.

Hence, Dr. Kettlewall predicted that a clean forest would have a light-colored moth and a polluted forest would have a dark-colored moth.

Why are there fewer tuskless elephants born after the war (ages 10-20 years old)?

Answers

Evolution of the elephants

Elephant tusks are either present or absent due to genetics, specifically the existence of key genes that regulate tusk growth. Environmental elements, however, can also affect the proportion of tuskless elephants in a population.

Elephants are frequently hunted down during conflicts or wars for their ivory tusks, which are highly sought-after on the illicit market. Over time, the population of elephants with tusks may decline as a result of this selective hunting of those with them.

The age range of 10 to 20 years old is essential because it coincides with the period of time when elephants usually begin to grow their tusks. Around the age of 6 to 8 years, young elephants may start developing their tusks, and by the time they are 10 to 20 years old, their tusks should typically be more noticeable and developed.

It is possible that many young elephants with developing tusks will be killed if a conflict or a period of rampant poaching takes place during this crucial time, which will reduce the number of tusked elephants in the population. After such a conflict or a period of heavy poaching, there can be a larger percentage of tuskless elephants between the ages of 10 and 20.

This theory makes the assumption that there was greater poaching or selective hunting occurring during the conflict, which would have a disproportionately negative effect on elephants with tusks. In order to provide a more comprehensive knowledge of the issue, additional examination of local conditions and data would be required. The individual situations and variables affecting elephant populations can differ.
