Answer:
e) Invertebrates lack a nervous system
Explanation:
One of the main characteristics of invertebrates is that they don't have a backbone. Backbones belong to the skeletal system. A totally different story is the nervous system which runs inside the backbone. Although the more complex nervous systems appear in vertebrates the simply fact of having eyes like crabs or insects implies having a nervous system that can control them.
An organ is a group of tissues working together to perform specific functions. An example of an organ is the heart.
Probably C. For example, you can tell how many amount of organism are in an ecosystem if you just check like a lot of animals live in hot climates while not many animals live in cold types of climates. I’m probably not making sense but I would put C.
The best way to explain the discrepancy between the normal length of prolactin (199 amino acids) and the length of the polypeptide synthesized in the experiment (227 amino acids) is that in the absence of Signal Recognition Particle (SRP) and the Endoplasmic Reticulum membrane,a prolactin precursor molecule is therefore synthesized.
Prolactin also plays a role in the stimulation of the proliferation of oligodendrocyte precursor cells.
Relating to all, The Signal Recognition Particle plays a crucial role in mediating the transport of secretory and membrane protein to the Endoplasmic Reticulum or plasma membrane.
This can occur both in the prokaryotic or eukaryotic cell.
Answer:
b carbon dioxide moves in; oxygen moves out.
Explanation:
- The green leaves of the plant convert the available solar energy into chemical energy by the process of photosynthesis which s responsible for giving green pigment to the leaves.
- The stomata present on the leaves are used for exchanging gases, they give out oxygen and take or absorb carbon gas. As carbon dioxide is exalted by animals and is taken by plants.
