tigry1 [53]

Answer:

Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals.

(google)

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).

what is true of intercellular signals that do not go through direct connections between cells such as gap junctions? (A.They eit
adell [148]

The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.

The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.

The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.

Explain how the heliocentric model has been modified with the help of telescopes and probes ?
baherus [9]

Answer:

They collect more information.

Explanation:

The heliocentric model has been modified with the help of telescopes and probes because telescopes and probes collect more accurate information about the solar system and planets. Due to information collected from these instruments, scientists are able to modify the heliocentric model more accurately. So we can conclude that with the help of telescopes and probes, the heliocentric model has been modified.
