Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
- <em>Negative feedbacks</em>
- <em>Positive feedbacks</em>
Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
Answer:
Mitosis produces all animal and plant cells, tissues, and organs excepts for the gametes ( the eggs and sperm). Since mitosis produces genetic clones of the parent cell when it divides, all animal and plant cells that grow from a fertilized egg (zygote) are more or less genetically identical.
Explanation:
Science
Microorganisms that live in severe habitats, such as very
hot, acidic, or salty environments are called extremophiles, which are
bacteria, archaea and eukaryotes. They are the most successful organisms
because they can adapt in any environment. They can live in oceans, rivers,
soil, and even inside a human’s body.
Answer:
Yes two diffrent genotypes can result in the same phenotype
Explanation:
Remember the recessive phenotype will be expressed only when the dominant allele is absent or when an individual is homzygous recessive
