For this question they’re referring to just the melting point part of the table. the melting point means they turn into a liquid at that certain point (or past it), so if their melting point is at less than 25 that means they’re liquids at room temp. If they melt at more than 25 then that means they are still solids at room temp.

Explain:<br> - Adult Cell Cloning<br> - Embryo Transplants<br> - Somatic Cell Nuclear Transfer
VikaD [51]

The method for adult cell cloning is: The nucleus is removed from an unfertilised egg cell. The nucleus from an adult body cell, such as a skin cell, is inserted into the egg cell. An electric shock stimulates the egg cell to divide to form an embryo.

An embryo transfer is the final stage in the In Vitro Fertilization (IVF) process where the fertilized egg—now an embryo—is placed in the woman's uterus. The embryo is loaded into a catheter, which is passed through the vagina and cervix and into the uterus where it is deposited.

In genetics and developmental biology, somatic cell nuclear transfer is a laboratory strategy for creating a viable embryo from a body cell and an egg cell. The technique consists of taking an enucleated oocyte and implanting a donor nucleus from a somatic cell. It is used in both therapeutic and reproductive cloning.

Which of these methods that aids in the movement of ions or molecules across a cell membrane requires the use of energy which is
olya-2409 [2.1K]

Answer:

D. Active transport.

Explanation:

Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.

The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.

The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
