Mitochondria are tiny organelles inside cells that are involved in releasing energy from food.
what's the powerhouse of the cell?The mitochondria, often mark the powerhouse of the cell, are the organelle in control of energy production within the cell. This procedure is known as cellular respiration. It is for this reason that mitochondria are often mentioned as the powerhouses of the cell.
It is known as the powerhouse of cells. It is because the mitochondrion is the area cells of cellular respiration where energy in the form of ATP (Adenosine triphosphate) is generated as a consequence of the oxidation of food constituents. This energy is needed for cells' various chemical activities required for life.
So we can conclude that Mitochondria are known as the powerhouse of cells.

Do some bacteria live symbiotically inside of the nematode? ( heart worm disease) Explain
Nematode-bacterium connections can range from facultative, transient interactions to stably maintained, protracted symbioses. They can also be helpful (mutualistic) or detrimental (pathogenic/parasitic).
Nematodes may be able to obtain nourishment from bacteria (Poinar and Hansen, 1986).
In what way are nematode worms symbiotic?
In general, it is thought that millipedes and nematodes have a commensal symbiotic connection. When millipedes consume nematode eggs while consuming organic waste, nematodes develop in the millipedes' intestines.
Do we coexist well with bacteria?
The human intestine and many of its symbionts have a mutually beneficial relationship: the human intestine feeds nutrition to the resident bacteria, while bacteria aid in food digestion and nutrient absorption, generate vitamins like biotin and vitamin K, and regulate immune system activity.

what role do Peppered Moths play in the FOOD
WEB?
Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and it remains a classic example in the teaching of evolution
What is Peppered Moths?A temperate species of night-flying moth is the peppered moth. In regions like Asia, Europe, and North America, it is primarily found in the northern hemisphere. Population genetics and natural selection are examples of evolution in the peppered moth.
It was eventually discovered that the colour was genetic. Moths bred new generations with their hue. Dark moth eggs became dark adults, while light moth eggs became light adults. All of the moth's offspring carry the mutant gene, which resulted in the dark colour due to a mutation in the moth's DNA.
Charles Darwin's theory of natural selection underwent its first test with the industrial melanism in the peppered moth, and it continues to serve as a model for evolution education today. It was referred to as "the clearest case in which a noticeable evolutionary process has actually witnessed" by Sewall Wright in 1978.

51. After eating breakfast, Nikka threw a ball in the air. What sequence describes the energy changes that occur from
the time she 2 points ate breakfast to the time she threw the ball?
A. electric to chemical to kinetic
B. chemical to kinetic to potential
C. kinetic to potential to chemical
D. potential to electrical to chemical
Chemical to kinetic to potential sequence describes the energy changes.
What is the sequence of energy transformations?
The sequence of energy transformations is the process of converting energy from one form to another. This process starts with the conversion of potential energy, or stored energy, into kinetic energy, or the energy of motion. Kinetic energy is then converted into thermal energy, or heat energy, through friction, and then into electrical energy through the use of generators. Electrical energy is then converted into light, sound, or mechanical energy, depending on the application. Finally, these forms of energy are converted back into potential energy, usually in the form of electricity stored in batteries.
When Nikka ate breakfast, the energy from the food was converted from chemical energy to kinetic energy as it was digested and metabolized. This kinetic energy was then converted to potential energy as Nikka moved around and built up energy before throwing the ball. This potential energy was then converted to kinetic energy as the ball moved through the air.
Therefore, chemical to kinetic to potential is the correct answer.

Plants, such as sunflowers, and animals obtain and process energy...
Answer:
The chloroplasts collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria.
Answer:
Photosynthesis
Explanation:
Plant cells obtain energy through a process called photosynthesis. This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. First, the energy from solar radiation is trapped in the plant. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants. Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction.

Dendrites receive information (chemical signals) from pre-synaptic neurons, then they process this information and transfer it to the soma as electrical impulses
What is dendrites?Appendages called dendrites are created so that cells can communicate with one another. They generate projections that are triggered by other neurons and transmit the electrical charge to the cell body, giving them the appearance of a tree-like structure (or, more rarely, directly to the axons). The cell body's specialized extensions are known as dendrites. They gather knowledge from other cells and transport it to other bodies. From the cell body to other cells, the axon transmits information. Dendrites, which resemble tree-like extensions at the beginning of a neuron, aid in boosting the cell body's surface area. These little protrusions communicate with the soma via electrical stimulation and take in information from neighboring neurons. There are synapses all over the dendrites as well.To learn more about dendrites refer to:

They are organized into long strands and are responsible for the transmission of genetic traits from parents to offspring. Humans have 23 pairs of chromosomes (or 46 total), each of which contains hundreds to thousands of genes.
Option A best matches the outcome because the male kittens only have one X chromosome, and if the recessive gene for deafness is present on that X chromosome, they will be deaf. The female kittens will have two X chromosomes, one from each parent. If the recessive gene for deafness is present on both X chromosomes, then they will be deaf. However, if the recessive gene is only present on one of their X chromosomes, then they will not be deaf. Therefore, half of the female kittens will be deaf.
