Scientists have successfully cloned animals, including mammals such as sheep. Which statement provides the most likely reason th

tigry1 [53]

Answer:

4) Some people consider human genetic experiments

unethical.

Explanation:

1) Humans have DNA that is structurally very different from

other mammals.

2) Cloning can only he performed on animals that normally

reproduce asexually.

3) Human genes are made of too many different types of

simple sugars.

4) Some people consider human genetic experiments

unethical.

The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.

Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.

Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.

Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.

The correct option is 4.

Juliette [100K]

Explanation:

This would be an example of secondary homeostasis

During wound healing, which happens after bleeding from a cut, the homeostatic response is clotting; primary homeostasis involves the formation of a platelet plug at the site, from platelets within the blood

Fibrinogen and platelets form a clot, in order to prevent blood loss and infection. Fibrin is formed through the activation of coagulation factors which stabilise the plug.

Further Explanation:

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

[FW.02]Which of these best matches surface features with the processes that are responsible for their formation?

DENIUS [597]

Answer:

O sinkholes, caves, and hot springs chemical and physical actions of groundwater.

Explanation:

Sinkholes, caves, and hot springs are formed from the actions of groundwater. The rock is made up of lime below the surface of sinkholes. These lime react with underground water and dissolve it which soften the rock and causes sinkholes. Caves are also formed when the water dissolve the limestone present in the rocks of the cave and slowly the degradation of rock will occur and caves are formed. Hot springs are formed when the groundwater is heated by the magma of the earth crust.
