How does mitochondria help the cell get the material it needs
Answer:
Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
Compare how the nervous system and endocrine system work to send messages through the human body.
Answer:
Here is Your answer vote me as brainlist.
Explanation:
One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.
The nervous system uses electrical and chemical signals to quickly send messages through the body, while the endocrine system uses hormones to gradually send messages through the bloodstream.
What is nervous and endocrine system?The nervous system uses electrical and chemical signals to transmit information rapidly and directly to specific target cells. This system is composed of neurons, which transmit impulses through the body, and specialized cells called neuroglia, which support and protect the neurons. The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord and the PNS includes the nerves that extend out to the rest of the body.
The endocrine system, on the other hand, uses hormones to transmit information more slowly and diffusely throughout the body. Hormones are chemical messengers that are secreted by glands and travel through the bloodstream to target cells. The endocrine system includes a variety of glands, such as the pituitary gland, thyroid gland, and adrenal gland, that produce hormones that regulate various physiological processes, such as growth, metabolism, and reproduction.

Give two uses of energy transferred by respiration in eukaryotes
Answer:
Most aerobic respiration takes place inside mitochondria. Some of the energy released in respiration is used to make larger molecules from smaller ones, to enable muscles to contract and to keep temperature steady. Some of the energy released in respiration in plants is used to make amino acids and proteins.
Explanation:google said it and i had this question in my science class and got it right
The uses of energy are - energy for metabolic reaction and growth and development of cells.
Cellular respiration provides energy with the series of complex chemical reaction cycles that is used for:
Working your muscles - for movement and physical activities energy is required.Growth and repair of cells - dividing cells, repairing them and development of the cells also require energy.Building larger molecules from smaller ones for instance proteins from amino acids.Allowing chemical reactions to take place.Absorbing molecules in active transport.Thus, The uses of energy are - energy for metabolic reaction and growth and development of cells.

Describe how radiocarbon dating method is used to find the absolute age of a fossil?
Answer:
Radiocarbon dating involves finding the age of an ancient fossil by measuring its carbon-14 content. Carbon-14 (radiocarbon), is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.

What type of protein helps molecules move through a
cell membrane?
Answer:
Gated Channel protein
Explanation:
Answer:
Water channel proteins are helps the molecules move through a cell membrane.
Explanation:
this protein acts like a pore in the membrane that lets water molecules or small ions through quickly. This proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate. Ion channel proteins allow ions to diffuse across the membrane.

why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Answer:
Deletion mutations can affect the entire base sequence.
Explanation:
Answer:
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

How do calcium ions help amplify the signal?
HELP PLEASE!!!
Answer:
Calcium signaling is the use of calcium ions (Ca2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins. Ca2+ can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.

If carbon dioxide was removed from a plant's environment, what would you expect to
happen to the plant's production of sugars?
O fewer sugars will be produced
more sugars will be produced
O carbon dioxide does not affect the production of sugars in plants
o the same number of sugars will be produced but without the carbon dioxide
Answer: Fewer sugars will be made because plants use carbon dioxide in photosynthesis.
Hope this helps
Plants are autotrophs, which prepare their food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.
The carbon dioxide is removed from the plant's environment, then less sugar will be produced.
Photosynthesis is a metabolic process in which plants prepare food in the presence of sunlight, carbon dioxide, and water. The products of photosynthesis are oxygen and sugar molecules.
The carbon dioxide if removed or reduced from the plant's environment, then the plants will be unable to perform photosynthesis properly, and in the limited resources, the products formed will be reduced.
Thus, the correct answer is Option A.

Explanation:
All the facts and observations gathered in an experiment are called data. Therefore, option B is correct.
What is an experiment?An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.
The three primary categories of scientific experiments are quasi-experimental, observational, and experimental (non-experimental). The most rigorous type of scientific investigation is experimental, often known as randomized control. The most control is present, as the name would imply.
Data are the facts and the observations gathered in an experiment. Therefore, option B is correct.
