What is the cell structure in a eukaryotic cell where aerobic respiration occurs

Answers

aerobic respiration takes place in the mitochondrion

The correct answer is mitochondria.

Aerobic respiration requires oxygen to function. The majority of the chemical activities taking part in the procedure occur in tiny objects within the cell cytoplasm, known as mitochondria. The energy discharged by respiration is utilized to produce big molecules from smaller ones.

More specifically, the process of aerobic respiration in eukaryotes takes place in the mitochondrial matrix or within the inner mitochondrial membrane of mitochondria.

In some ecosystems, succession increases the chance of disturbance. in these ecosystems, __________.

Answers

The answer is that in these ecosystems, climax community may not occur. Ecological succession is the gradual process in which ecosystems change and develop over time, thus nothing remains the same and also the habitats are constantly changing. There are two main types of biological successions;primary succession which is an opening of a pristine habitat and the secondary succession which is a response to a disturbance.
There are ecosystems like cyclic succession that has a concept of community ecology that may result to increase chance of disturbance when climax communities may not occur. This is a pattern of a small number of species that tend to replace each other over time in the absence of large-scale disturbance, long-term physical changes in the environment and an end-state climax community with stable species compositions.

Which of the following epochs was the warmest?

Answers

This question is incomplete. The options are:
a. Oligocene b. Eocenec. Miocened. Pleistocene

Option b is correct. This relates to the Paleocene-Eocene Thermal Maximum (PETM) which occured around 56 million years ago and was similar to modern-day climate change. Warming of more than 5 degrees Celcius occured over 15-20 thousand years because of input of more than 2000 gigatons of carbon into the atmosphere. The PETM resulted in mass deep ocean extinctions and mass terrestrial and shallow ocean diversification.

An 8-ounce glass of low-fat chocolate milk contains 160 kilocalories (kcal) and 8 grams of protein. what percent of the kcal in the milk comes from protein?

Answers

Protein has 4 calories per gram. Since this glass of chocolate milk has 8 grams of protein, it has 32 (4*8) calories which originate from protein. Given that the total amount calories contained in this glass are 160, the percentage of calories coming from protein is (100*32)/160 = 20%.

Final answer:

Protein provides 4 kilocalories per gram. Multiplying the 8 grams of protein in the milk by 4 kcal/g gives 32 kilocalories from protein. This makes up 20% of the total 160 kilocalories in the milk.

Explanation:

To calculate what percent of the kilocalories in the milk come from protein, we need to know how many kilocalories are provided by the protein. Protein provides 4 kilocalories per gram, so if the milk contains 8 grams of protein, the protein contributes:

8 grams of protein x 4 kcal/g = 32 kilocalories from protein.

Next, we'll find the percentage of the total calories that come from protein:

(32 kilocalories from protein / 160 total kilocalories) x 100 = 20%

Therefore, 20% of the kilocalories in the low-fat chocolate milk come from protein.

When a spinning ice skater pulls in his arms, he spins faster because __________?

Answers

I think this is because his angular momentum must be conserved, so reducing his radius must increase his speed of rotation. When a figure skater draws his arms and a leg inwards, he reduces the distance between the axis of rotation and some of his mass, reducing the moment of inertia. Since angular momentum is conserved, his rotational velocity must increase to compensate.

Which sentences describe decomposers in a food chain

Answers

1 and 4. they both state what decomposes do and mean to the food chain

Bacteria, fungus, worms, and snails recycle the waste of dead materials and give back nutrients to the ecosystem, according to the definition of decomposers in a food chain. So, the correct option is D.

What are Decomposers?

Organisms known as decomposers convert decayed organic matter, such as that of dead plants and animals, into more basic substances like nutrients and minerals. Following their release back into the ecosystem, these less complex substances are utilised for growth and development by other organisms.

By dissolving decayed organic debris and returning the nutrients to the soil, which plants can use to thrive, decomposers perform a critical function in the ecosystem. By preventing nutrients from being lost and allowing them to be reused by other living things, this recycling mechanism aids in maintaining ecological equilibrium.

Bacteria, fungus, worms, and snails recycle the waste of dead materials and give back nutrients to the ecosystem, according to the definition of decomposers in a food chain.

Therefore, the correct option is D.

Which is an important part of the endocrine system but is not an endocrine gland?

Answers

The hypothalamus. :)

The pancreas is an important part of the endocrine system but is not an endocrine gland.

The pancreas plays a crucial role in regulating blood sugar levels and is a vital component of the endocrine system. It contains clusters of cells called the Islets of Langerhans, which house two important types of cells: alpha cells that secrete glucagon and beta cells that secrete insulin. These hormones are essential for regulating glucose metabolism and maintaining blood sugar within a healthy range.

When blood sugar levels rise after a meal, beta cells release insulin to help cells absorb glucose for energy. Conversely, when blood sugar levels drop, alpha cells release glucagon to stimulate the release of stored glucose from the liver. While the pancreas primarily functions as an exocrine gland, producing digestive enzymes, its role in regulating blood sugar exemplifies its critical endocrine function.

A succulent plant is grown in a low light situation so that it is very tall. pale, and has few leaves compared to its siblings grown in full sun. Is this an evolutionary change or not, and why?

Answers

This is not an evolutionary change. This is called etiolation which is a process by plants grown in the absence of sunlight. This can manifested by plants through weaker stems, fewer leaves, longer internodes and pale to yellowish color of plants. This is not an optimum condition for plants as they cannot adapt in the changes in the enviroment. 
Not evolution because of no genetic changes or phenotypic change

In a living organism, evolution is growing in the heritable traits of biological communities over succeeding generations. A mutation that is a permanent modification in the DNA chain that makes up a gene, so that the progression varies from what is discovered in maximum plants. On the other hand, phenotypic variation is due to underlying heritable genetic modification. This is a major requirement for development by natural preference which is not found in succulent plant.

what are two major forces that shape and reshape earth? describe how each force works too please?

Answers

The two major forces that shape/reshape the earth are internal forces, i.e.volcanoes and earthquakes and external forces, i.e. weather and the ocean, both of which cause erosion. Volcanoes can add landmass but also can destroy land or cause a winter-like state caused by ash in the atmosphere which can block out the sun and possible killing vast amounts of plant and animal life. Earthquakes can change the land by process of subduction where one plate (land surface or ocean bottom) is forced under another. Erosion wears down geologic formations by the actions of wind and water. Over time water can carve valleys or canyons. Ocean water can erode coastlines by the constant beating of waves on the shore. Wind can carry away particles of land and deposit them elsewhere. Wind and weather combined can be a powerful force for reshaping the earth.

How does the primary transcript in the nucleus of a eukaryotic cell compare to the functional mrna?

Answers

The primary transcript in the nucleus of a eukaryotic cell is a messenger RNA but it is not yet functional. There will still be non-coding parts of the mRNA that needs to be removed (introns) and then coding parts must be spliced together (exons). After which, there is capping of the mRNA (5' or 5 prime capping) with 7-methylguanylate. There will also be adding multiple adenine residues in the 3' end of the mRNA called polyadenylation resulting to a poly-A tail at the 3' end of the mRNA. mRNA with spliced exons, a 5' cap, and a poly-A tail is now a functional RNA.

Which part of the neuron sends messages to other neurons?

Answers

Answer: Axon

An axon is part of neuron with long single fiber that sends messages to the dendrites of other neurons. They transmit information away from the cell body and may have myelin covering to protect the axon and help to fasten the speed of transmission of the signal that deliver the message to other neurons, tissue like the muscles and organs.

Final answer:

The axon of the neuron is responsible for sending messages to other neurons. It transmits electrical signals known as action potentials, which trigger the release of neurotransmitters at the axon terminals. These neurotransmitters then carry the message across the synaptic gap to the next neuron.

Explanation:

In a neuron, the part that sends messages to other neurons is called the axon. The neuron generates an electrical signal known as an action potential, which travels down the axon towards the axon terminals. There, it triggers the release of neurotransmitters, which are chemical messengers that transmit the signal to the next neuron across the synaptic gap.

The typical neuron structure comprises the cell body, dendrites, axon, and axon terminals. Out of these, the axon plays a pivotal role in carrying these messages or impulses from the neuron to other neurons, which could be located in different parts of the body.
