Answer:
Organisms need to detect and respond to changes in their internal and external environment. This is because the conditions inside our body must be carefully controlled for it to function effectively and survive. The control systems that allow organisms to respond to changes are incredibly important.
All control systems include:
Cells called receptors, which detect stimuli (changes in the environment).
The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the body.
Effectors which bring about responses, and restore optimum levels, such as core body temperature and blood glucose levels. Effectors include muscles and glands, and so responses can include muscle contractions or hormone release
Hi! help here thanks
Answer:
Observations are things that can be directly seen and talked about. Inferences are things that you believe correlate with each other. For instance, the dog wagging its tail must be happy because it is a guess, not a fact. An example of an observation is The girl is wearing a blue shirt with white straps because you can directly see it.

(Please help!!) How does the diagram illustrate the relationship between respiration and photosynthesis? Explain this relationship.
Explanation:
the diagram illustrate the relationship between respiration and photosynthesis by animal need oxygen and throw the carbondioxide and plant need carbondioxide and throw oxygen and plant is grow by decayed things because decayed thing help to soil fertility then their relation ship is very strong
During photosynthesis plants takes carbon dioxide from atmosphere and gives out oxygen which is taken up by animals and releases carbon dioxide during respiration.
What is photosynthesis?"The process by which plants makes their own food in presence of sunlight, chlorophyll and carbon dioxide is known as photosynthesis."The end products of this process are glucose and oxygen.The plants store glucose in the form of starch and releases oxygen into the atmosphere.What is respiration?"The process by which cells use oxygen to break down sugar and obtain energy is called respiration."The animals release carbon dioxide into environment.
Hence, the carbon cycle is maintained between respiration and photosynthesis.

explain why clones can be produced from a single body cell of a adult?
Answer:
To make a clone, scientists transfer the DNA from an animal's somatic cell into an egg cell that has had its nucleus and DNA removed. The egg develops into an embryo that contains the same genes as the cell donor. Then the embryo is implanted into an adult female's uterus to growCloning of human cells is a technology that holds the potential to cure many diseases and provide a source of exactly matched transplant tissues and organs. One cloning technology that has been developed for mammalian and human cells is somatic cell nuclear transfer (SCNT).

Negative feedback results in the inhibition of an enzyme in a biochemical pathway, reducing the activity of earlier enzymes, and stopping the pathway. Positive feedback results in the activation of more enzymes, thus increasing its production of the product.
Describe a phase of mitosis?
Mitosis is the division of a parent cell into two daughter cells which contain the genetic material which is exactly similar to parents. The daughter cells are often called as clones.
What is Mitosis?
Mitosis is also known as Equational division. Mitosis is the process of cell division, in which the nucleus undergoes division in eukaryotic cells that occurs when a parent cell undergoes division to produce two identical daughter cells.
During the process of cell division, the karyokinesis is followed by the cytokinesis. Karyokinesis is the division of nucleus and it is divided into four phases: Prophase, Metaphase, Anaphase, and Telophase. In the prophase of mitosis, the spindle fibers starts attaching to the chromatids of chromosomes and the chromatids becomes distinct which are then arranged on the equatorial plane and later divides into two daughter cells.

A triplet of bases in a template strand of DNA is CAG. What would be the corresponding codon for mRNA?
GTC
GUC
GTU
GUU
Answer:
GUC would be the corresponding codon for mRNA.
The corresponding codon for mRNA is GUC.
The instructions of the cellular process are encoded in the form of triplets of bases called codons.
The process of transcription forms the transcript of the DNA molecule in the form of an RNA called mRNA.The sequence of the mRNA is determined by the sequence of the bases of DNA and the new nucleotides are added in accordance with the Chargaff rule.The Chargaff rule suggests that A will bind T (U in case of RNA) and G will bind C.Since the DNA codon is the 5' CAG 3' the nucleotides added will be in sequence 3' GUC 5'.Thus, A triplet of bases in a template strand of DNA is 5' CAG 3' then the corresponding codon for mRNA- 3' GUC 5'.
